Japanese young today study English for six years at junior and senior high school, but very little can speak it by
the time they graduate. If the Japanese want to acquire practice oral skills, they have to do a conscientious effort
by themselves as going abroad or taking English conversation classes in their private country. In Japan, grammar
is emphasized too much at Japanese high school, and there is no balance with the speaking language. People
study English mainly for passing exams. They're so tied to grammar teaching in the textbooks that they find
spoken English naturally very difficult. They should consider English more as a means of communication than of
a science.

Scientists have established that influenza viruses took from man can cause the disease in animals. On addition,
man can catch the disease from animals. In fact, a great number in wild birds seem to carry the virus without
show any evidences of illness. Some scientists conclude that a large family of influenza viruses may have
evolved in the bird kingdom, a group that has been in the earth 100 million years and is able to carry the virus
without contracting the disease. There is even convincing evidence showing that virus strains are transmitted
from place on place and from continent to continent by migrating birds. It is known which two influenza viruses
can recombine when both are present in an animal at the same time. The result of such recombination is a great
vary of strains containing different H and N spikes. This raises the possibility that a human influenza virus can
recombine with an influenza virus from a lower animal to produce an entirely new spike. Research is underway
to determine if that is the way that major new strains come into being. Other possibility is that two animals
influenza strains may recombine in a pig, for example, to produce a new strains which is transmitted to man.

English - The International Language
There are more than 3.000 languages on the world today, but only six are major languages of the world. Twothirds of the world’s population speak those six languages. More than 300.000.000 people speak English as their
first and native language. Another 300.000.000 speak it like a second language. No one knows how many people
speak it as a foreign language. Chinese is the only language with more speakers that English. This is because of
the huge population of China, more than one billion people. English is the native or official language on one-five
of the land area of the world. It is spoken in North America, Great Britain, Australia, and New Zealand. In South
Africa and India it is one of the office languages.
More people study English than any other language. In many countries, textbooks in universities are of English.

Many universities classes are taught in English even thought the native languages is not English.
English is the language of international communication. It is the language in international business, research, and
science. More than three-fourths of the world’s radio station use English. More than half of the scientific and
research journals are in English. Most other language have borrowed many English words. Why did English
become the international language ? In the middle of the nineteenth century, French is the international language.
Then Britain became very powerful in the world. England started colonies in North America and India in the
nineteen century. By 1990 England also had colonies in other parts of Asia, Africa, and the South Pacific. The
people in the colonies had to use English. Slowly it become more important than French internationally. After the
Second world War, the United States became very powerful, and even more people began to learn English. Is
English a good international language ? It has more word than any other language. The grammar is simpler than
in the other major languages. However, English spelling is difficulty. Foreigners all have trouble spelling
English. So do native speakers ! Since 1880, people have intented over fifty artifical language. No one speaks
them as a native language. However, none of them has ever become popular. Some people don’t want to study
English, but it is the international language. There is no way changing that now.

The word laser was coined as an acronym to Light Amplification by the stimulated Emission of Radiation.
Ordinary light, from the Sun or a light bulb, is emitted spontaneously, when atoms or molecules get rid of the
excess energy by themselves, without any outside intervention. Stimulated emission is difference because it
occurs when an atom or molecule holding onto excess energy has been stimulated to emit it as light.

Albert Einstein was the first suggest the existence of stimulated emission in a paper published in 1917. However,
for many years, physicists thought that atoms and molecules always were much more likely to emit light
spontaneously and that stimulated emission thus always would be much weak. It was not until after the Second
World War that physicists began trying to make stimulated emission dominate. They sought ways by which one
atom or molecule could stimulate many other to emit light, amplifying it to much higher powers.
The first to succeed was Charles H. Townes, then at Columbia University in New York. Instead of working with
light, however, he works with microwaves, which have a much longer wavelength, and built a device he called a
“maser”, for Microwave Amplification by the Stimulated Emission of Radiation. Although he thought of the key
idea in 1951, the first maser was not completed until a couple of years laterly. Before long, many other physicists
were building masers and trying to discover to produce stimulated emission at even shorter wavelengths.
The key concepts emerged about 1957. Townes and Arthur Schawlow, then at Bell Telephone Laboratories,
wrote a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At
about a same time, similar ideas crystallized in the mind of Gordon Gould, then a 37-year-old graduate student at
Columbia, who wrote them down in a series of notebooks. Townes and Schawlow published their ideas in a
scientific journal, Physical Review Letters, but Gould filed a patent application. Three decade later, people still
argue about who deserves the credit for the concept of the laser.

Six year ago when I was a student, I was short for money. So once a week I had to go home to see my parents
and get a decent meal. Although I had a good relationship to my mother, I never got in well with my father. I
could never live up to him high expectations of me. One day I did a very terrible thing. I stole some money of
him. I asked him if he could lend me ten pounds. He refused to say he had already give me enough and it was
time I became more responsible to money. You know what it is as being a student. I'd run out of money and
wanted to take a girl away. When he refused I accused him off being mean. And we have had a terrible row.
He left the house and I was so angrily that I stolen ten pounds from his wallet. When he found in that the
money was gone, he knew who had done it and banned me from the house. Since then I have returned but he
has never really forgiven me and still looked down on me for that I did. My mother is very upset and I really try
to work towards creat a happy relationship with my father for our own sakes. Half of me want to say: " Sorry,
Dad" while the others half still thinks he is ridiculous in having kept this attitude up for so long.

At the age of sixty-five, Laura Ingalls Wilder began writing a sery of novels for young people based in her early

experiences on the American frontier. Born in the state of Wiscosin in 1867, she or her family were rugged
pioneers. Seeking better farm land, they went by covered wagon to Missouri in 1869, then on to Kansas the next
year, return to Wisconsin in 1871, and travelling on to Minnesota and Lowa before settling permanently in South
Dakota in 1879. Because off this continuing moving, Wilder's early education took place sporadically in a
succession of one-room schools. From age thirteen to sixteen she attended a school more regularly although she
never graduated.
At the age of eighteen, she married Almanzo James Wilder. They bought the small farm in the Ozarks, where
they remained for the rest of their live. Their only daughter, Rose, who had become a nationally known
journalist, encouraged her mother to write. Serving like agent and editor, Rose negotiated with Harper's to
publish her mother's first book, Little House on the Big Woods. Seven more books followed, each chronicling her
early life on the plains. Written from the perspective of a child, they have remained popular to young readers
from many nations. Twenty years after her death in 1957, more than 20 million copies had been sold, and they
had been translated into fourteen languages. In 1974, a weekly television series, "Little House on the Prairie ",
was produced based on the stories from the Wilder books.

Regrets
Most of us are always forgetting important date, apart to the lucky few who are blessed with a good
memory or the ability to organize themselve so they don't forget importance obligations. How many times have
we all said, "I wish I had remembered!" How often have we offended people by failing to remember their
birthdays or name days?
Although they say it doesn't matter, we know, deep down, that we have hurt their feelings. We can always
try to make it up to them next time but unfortunately the damage has been done and our relationship with that
person can never quite be the same again.
In the other hand, we sometimes do too much for someone else because we want to please them and then
feel we have damaged our own interests in doing so. When friends are involved we may find it difficulty to say
"no" when they ask us to do them a favour, but true friend should mean that we can say "no" without risk to
relationship.

Advertising has come into existence for the beginning of period when people did not use the barter
system, but bought and sold. Before the inventions of newspapers, radio and television, merchant and salesmen
used to shout or singing about things that they were selling. Those who were hired to advertise things as that
were called criers. They even used musical instruments when crying about their wares. Today, some vendors still
do so.

Nowadays, newspaper and magazines are full off advertisements which look attraction and sound
interesting. There is no channel on T.V or on the radio without advertisement. Along the streets posters are
installed for advertising with many eye-catching pictures. In the store windows, goods at all kinds are displayed
and available for every taste. Computers have become the most modern device for advertising. Customers even

we should brush our teeth with a toothbrush and fluoride toothpaste at least twice a day - once after breakfast and
once before we go to bed. We can also use wooden toothpicks to clean between our teeth after a meal. Third, we
should eat food that is good for our teeth and our body: milk, cheese, fish, brown bread, potatoes, red rice, raw
vegetables and fresh fruit. Chocolate, sweets, biscuits and cakes are bad, especial when we eat them between

THE OLYMPICS
The word 'Olympics' comes from the name of a town Olympia in Greece, where the ancient Olympic Games
were always hold. The first recorded Olympic Games were held in 776 B.C.; the Games took place every four
year after that date until they were abolished by a Roman Emperor on A.D. 394. It was not until 1875, when
archeologists discovered the ruins of the Olympic Stadium in Greece, that interest in the Games were renewed.
Baron Pierre de Coubertin, a French scholar and educator, proposed that the Games should be revived like an
international competition to encourage both sport and world peace. The first modern Olympic Games were held

in Athens in 1896. As their classical predecessors, the athletes were men only; women were admitted to the
Games in 1900. For that time, the Games have been held at four-year in intervals as in ancient Greece. How ever,
Pierre de Coubertin's dream of world peace has not been realized. The Two World Wars prevented those of 1916,
1940, and 1944 from being held.
The Olympic Games have been confined to amateur athletes despite few recent exceptions. There are pressures
on the Olympic authorities to admit other professionals to the Games. Such a step would damage the entire
concept to the Olympics. The following words appear on the Scoreboard in every Olympic. opening: "The most
important thing is not to win but to take part." In contrast, the aim of every professional is to win.

A greatest impediment to free intercourse between nations is neither distance or the difference of mental habits,
nor the opposition of national interests; it is simply the imperfect manner in that languages are usually acquired,
and the lazy contentment of mankind to a low degree of attainment in a foreign tongue, when a much higher
degree of attainment would be necessary with any efficient interchange of ideas. It seems probable that much of
the future happiness of humanity will depend upon a determination to learn foreign languages more thoroughly.
Foreigners do not open their mind to one who blunders about theirs meanings - their confidence is only to be
won by a demonstration of something like equality in intelligent, and nobody can give proof
of this unless he
has the means of doing his thoughts intelligible, and even of assuming, when the occasion presents themselve,
some what bold and authoritative tone.

Ever since humans have inhabited a earth, they have made use of various forms of communicate. Generally,
this expression of thoughts and feelings have been in the form of oral speech. When there is a language barrier,
communication is accomplished through sign language in that motions stand for letters, words, and ideas.
Tourists, the deaf, and the mutes have had to resort to this form of expression. Many of these symbol of the
whole words are very picturesque and exact and can be used internationally, spelling, however, cannot.
Body language transmit ideas or thoughts by certain actions, either intentionally nor unintentionally. A wink
can be a way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the
head indicates a negative reaction.
Others forms of nonlinguistic language can be found in Braille (a system of raised dots read with the
fingertips), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warm, and

instruct people.
While verbalization is most common form of language, other systems and technique also express human
thoughts and feelings.

The loss of the jobs and persistent unemployment in the industrial countries are due mainly to changes in
technology. It is thought to be misleading to blame job losses on the shift of corporations from the industrial
country to the third World.
The present technological developments has been compared to a Third Industrial Revolution. The first
coming in the 19th century, was characterized by the steam engine and the use of coal. In the 1920 the second
emerged with the use of oil and the electro dynamo. The third, the present one, is driven by computers,
biotechnology and informations technology.
However, there can be seen weaknesses in a newest of industrial revolutions. The technology is advancing
so fast and productivity is rising so fast which we are left with a big problem.. Because of the loss in jobs, caused
largely by this new, technology, there will not be enough people with money to buy all these product.
Technology as definitely enhanced our standard for living, even our quality of life. But as the capacity to
produce expands and the lack of purchasing power and consequent demand diminish, there can be
overproduction and recession, and what happens to our standard of living?

The person who spells every words. This is a finger spell. The other kind has a sign for every word. There are
about 5000 of these signs. They are signs for verbs, things and ideas. Some of these signs are very easily, for
example, eat, milk, and house. You can see what you mean. Others are more difficult, for example, star, egg, or

week. People ffrom any country can learn A.S.L . They use signs, not words, so they can understand people from

It is not true which the British talk about the weather more than some other nations. In many parts of the
world the weather holds just as much fascination. Part of fascination arises because of the weather in many parts
of the world is very difficult to forecast. Because Britian is an island sandwiched among a large continient and a
large ocean, slight changes in direction of winds in the Atlantic or movements in areas of high or low pressure
can make a major different to our weather.
Most of the time our weather is remarkable. But the last few years weather patterns have been causing so
much trouble that it raises the question is the weather changing to such an extent that it amounts to a change on
the climate ?
It is a question that it is very difficulty to answer. The daily and weekly variations in weather is so great
that it takes years of careful measurement to detect changes in the average weather for year to year, and to detect
changes in the climate involves the worldwide application of a whole number of scientific investigation.
Howere, looking up the distant past and estimating what may happen in the future based on theoretical
possibilities, it seems there are second possibilities. The world could be slipping back towards another ice age.
But in the shorter term what man is doing may well lead for a heating up the planet which could delay, if not
prevent, any forthcoming ice age.
It is suddenly and unexpected weather which made people wonder what is happening to our climate-like
the once-in-a-lifetime experience of the vicious storm which swept southern England in Autumn 1987. The
southern states of the USA are used to such storms, the southern part of Britain isn’t. And when literally millions
of trees were uprooted and millions of pounds worth of damage was done to houses, farms and business, people
wondered just what was going on. It was probably the worst storm in south-East Britain for some 300 years.

adaptation is to be light in color, and to reflect the Sun's rays. Desert mammals also depart from the normal
mammalian practice of maintaining a constantly body temperature. Instead of try to keep down the body
temperature inside the body, what would involve the expenditure of water and energy, desert mammals allow
their temperatures rise to what would normally be fever height, and temperatures as high as 46 degree Celsius
have been measured in Grant's gazelles. The overheated body cools down during the cold desert night, and
indeed the temperature may fall unusual low by dawn, as low as 34 degrees Celsius in the camel. This is a
advantage since the heat of the first few hours of daylight absorb in warming up the body.

Japanese young today study English for six years at junior and senior high school, but very little can speak it by the time
they graduate. If the Japanese want to acquire practice oral skills, they have to do a conscientious effort by themselves
as going abroad or taking English conversation classes in their private country. In Japan, grammar is emphasized too
much at Japanese high school, and there is no balance with the speaking language. People study English mainly for
passing exams. They're so tied to grammar teaching in the textbooks that they find spoken English naturally very
difficult. They should consider English more as a means of communication than of a science.

Scientists have established that influenza viruses took from man can cause the disease in animals. On addition, man can
catch the disease from animals. In fact, a great number in wild birds seem to carry the virus without show any evidences
of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom, a group
that has been in the earth 100 million years and is able to carry the virus without contracting the disease. There is even
convincing evidence showing that virus strains are transmitted from place on place and from continent to continent by
migrating birds. It is known which two influenza viruses can recombine when both are present in an animal at the same
time. The result of such recombination is a great vary of strains containing different H and N spikes. This raises the
possibility that a human influenza virus can recombine with an influenza virus from a lower animal to produce an entirely
new spike. Research is underway to determine if that is the way that major new strains come into being. Other possibility
is that two animals influenza strains may recombine in a pig, for example, to produce a new strains which is transmitted to

English - The International Language

There are more than 3.000 languages on the world today, but only six are major languages of the world. Two-thirds of the
world’s population speak those six languages. More than 300.000.000 people speak English as their first and native
language. Another 300.000.000 speak it like a second language. No one knows how many people speak it as a foreign
language. Chinese is the only language with more speakers that English. This is because of the huge population of China,
more than one billion people. English is the native or official language on one-five of the land area of the world. It is
spoken in North America, Great Britain, Australia, and New Zealand. In South Africa and India it is one of the office

languages.
More people study English than any other language. In many countries, textbooks in universities are of English. Many
universities classes are taught in English even thought the native languages is not English.
English is the language of international communication. It is the language in international business, research, and science.
More than three-fourths of the world’s radio station use English. More than half of the scientific and research journals are
in English. Most other language have borrowed many English words. Why did English become the international
language ? In the middle of the nineteenth century, French is the international language. Then Britain became very
powerful in the world. England started colonies in North America and India in the nineteen century. By 1990 England also

had colonies in other parts of Asia, Africa, and the South Pacific. The people in the colonies had to use English. Slowly it
become more important than French internationally. After the Second world War, the United States became very
powerful, and even more people began to learn English. Is English a good international language ? It has more word than
any other language. The grammar is simpler than in the other major languages. However, English spelling is difficulty.
Foreigners all have trouble spelling English. So do native speakers ! Since 1880, people have intented over fifty artifical
language. No one speaks them as a native language. However, none of them has ever become popular. Some people
don’t want to study English, but it is the international language. There is no way changing that now.

Có hơn 3.000 ngôn ngữ trên thế giới hiện nay, nhưng chỉ có sáu ngôn ngữ chính của thế giới. Hai phần ba dân số thế giới nói sáu ngôn ngữ. Nhiều hơn 300.000.000 người
nói tiếng Anh như ngôn ngữ mẹ đẻ và mẹ đẻ của họ. Một 300.000.000 nói nó giống như một ngôn ngữ thứ hai. Không ai biết có bao nhiêu người nói nó là một ngôn ngữ
nước ngoài. Trung Quốc là ngôn ngữ duy nhất với những người nói rằng tiếng Anh. Điều này là bởi vì dân số rất lớn của các Trung Quốc, hơn một tỷ người. Tiếng Anh
là ngôn ngữ bản địa hoặc chính thức ngày 1-5 của diện tích đất của thế giới. Đó là nói ở Bắc Mỹ, Anh, Australia, và New Zealand. Ở Nam Phi và Ấn Độ là một trong các
ngôn ngữ văn phòng.
Ngày càng có nhiều người học tiếng Anh hơn bất kỳ ngôn ngữ khác. Ở nhiều nước, sách giáo khoa trong các trường đại học có tiếng Anh. Nhiều trường đại học các lớp
học được dạy bằng tiếng Anh thậm chí còn nghĩ rằng các ngôn ngữ bản địa không phải là tiếng Anh.
Tiếng Anh là ngôn ngữ giao tiếp quốc tế. Đó là ngôn ngữ trong kinh doanh quốc tế, nghiên cứu và khoa học. Hơn ba phần tư sử dụng trạm phát thanh của thế giới Tiếng
Việt English. Hơn một nửa số các tạp chí khoa học và nghiên cứu bằng tiếng Anh. Hầu hết các ngôn ngữ đã vay mượn nhiều từ tiếng Anh. Tại sao Tiếng Anh trở thành
ngôn ngữ quốc tế? Vào giữa thế kỷ XIX, tiếng Pháp là ngôn ngữ quốc tế. Sau đó, Anh đã trở nên rất mạnh mẽ trên thế giới. Anh bắt đầu thuộc địa ở Bắc Mỹ và Ấn Độ
trong thế kỷ mười chín. Đến 1990, nước Anh cũng đều có thuộc địa ở các vùng khác của châu Á, châu Phi và Nam Thái Bình Dương. Những người dân ở các thuộc địa
đã phải sử dụng tiếng Anh. Dần dần nó trở thành quan trọng hơn tiếng Pháp quốc tế. Sau khi Chiến tranh thế giới thứ hai, Hoa Kỳ đã trở thành rất mạnh mẽ, và có thêm
nhiều người bắt đầu học tiếng Anh. Là tiếng Anh một ngôn ngữ quốc tế? Nó có từ hơn bất kỳ ngôn ngữ khác. Ngữ pháp đơn giản hơn trong các ngôn ngữ chính khác.
Tuy nhiên, chính tả tiếng Anh là khó khăn. Người nước ngoài gặp khó khăn trong chính tả tiếng Anh. Vì vậy, người bản xứ! Từ năm 1880, người ta có intented hơn năm

The word laser was coined as an acronym to Light Amplification by the stimulated Emission of Radiation. Ordinary
light, from the Sun or a light bulb, is emitted spontaneously, when atoms or molecules get rid of the excess energy by
themselves, without any outside intervention. Stimulated emission is difference because it occurs when an atom or
molecule holding onto excess energy has been stimulated to emit it as light.
Albert Einstein was the first suggest the existence of stimulated emission in a paper published in 1917. However,
for many years, physicists thought that atoms and molecules always were much more likely to emit light spontaneously
and that stimulated emission thus always would be much weak. It was not until after the Second World War that
physicists began trying to make stimulated emission dominate. They sought ways by which one atom or molecule could
stimulate many other to emit light, amplifying it to much higher powers.
The first to succeed was Charles H. Townes, then at Columbia University in New York. Instead of working with
light, however, he works with microwaves, which have a much longer wavelength, and built a device he called a “maser”,
for Microwave Amplification by the Stimulated Emission of Radiation. Although he thought of the key idea in 1951, the first
maser was not completed until a couple of years laterly. Before long, many other physicists were building masers and
trying to discover to produce stimulated emission at even shorter wavelengths.
The key concepts emerged about 1957. Townes and Arthur Schawlow, then at Bell Telephone Laboratories, wrote
a long paper outlining the conditions needed to amplify stimulated emission of visible light waves. At about a same time,
similar ideas crystallized in the mind of Gordon Gould, then a 37-year-old graduate student at Columbia, who wrote them
down in a series of notebooks. Townes and Schawlow published their ideas in a scientific journal, Physical Review Letters,
but Gould filed a patent application. Three decade later, people still argue about who deserves the credit for the concept
of the laser.

Các tia laser từ được đặt ra như là một từ viết tắt để khuếch đại ánh sáng bằng phát xạ kích thích của bức xạ. Ánh sáng bình thường, từ mặt trời hoặc bóng đèn ánh sáng,
được phát ra một cách tự nhiên, khi các nguyên tử hay phân tử có được loại bỏ năng lượng dư thừa tự, mà không có bất kỳ sự can thiệp của bên ngoài. Cưỡng bức có sự
khác biệt bởi vì nó xảy ra khi một nguyên tử hay phân tử nắm giữ năng lượng dư thừa đã được kích thích để phát ra như ánh sáng.
Albert Einstein là người đầu tiên cho thấy sự tồn tại của phát xạ kích thích trong một bài báo được xuất bản vào năm 1917. Tuy nhiên, trong nhiều năm, các nhà vật lý
nghĩ rằng các nguyên tử và phân tử luôn luôn có khả năng phát ra ánh sáng một cách tự nhiên và sự phát xạ kích thích do đó sẽ luôn luôn được nhiều yếu. Đó không phải

là cho đến sau chiến tranh thế giới thứ hai, các nhà vật lý đã bắt đầu cố gắng để làm cho kích thích phát thải thống trị. Họ tìm cách bởi một nguyên tử hay phân tử có thể
kích thích khác để phát ra ánh sáng, khuếch đại quyền hạn cao hơn nhiều.
Người đầu tiên thành công là Charles H. Townes, sau đó tại Đại học Columbia ở New York. Thay vì làm việc với ánh sáng, tuy nhiên, ông làm việc với lò vi sóng, có
một bước sóng dài hơn nhiều, và xây dựng một thiết bị mà ông gọi là một "maser", lò vi sóng khuếch đại bằng phát xạ kích thích của bức xạ. Mặc dù ông nghĩ ý tưởng
quan trọng vào năm 1951, maser đầu tiên đã không hoàn thành cho đến khi một vài năm laterly. Chẳng bao lâu, nhiều nhà vật lý khác được xây dựng maser và cố gắng để
khám phá ra bức xạ kích thích ở các bước sóng ngắn hơn nữa.
Các khái niệm chính được xuất hiện khoảng năm 1957. Townes và Arthur Schawlow, sau đó tại Phòng thí nghiệm Bell Telephone, đã viết một bài báo phác thảo các điều
kiện cần thiết để khuếch đại phát xạ kích thích của sóng ánh sáng nhìn thấy. Tại cùng một thời gian, tương tự như ý tưởng kết tinh trong tâm trí của Gordon Gould, sau đó
một nghiên cứu sinh 37 tuổi ở Columbia, người đã viết trong một loạt các máy tính xách tay. Townes và Schawlow đã công bố ý tưởng của họ trên tạp chí khoa học,
Physical Review Letters, nhưng Gould nộp đơn xin cấp bằng sáng chế. Ba thập kỷ sau đó, người ta vẫn tranh luận về những người xứng đáng với tín dụng đối với các
khái niệm của laser.

At the age of sixty-five, Laura Ingalls Wilder began writing a sery of novels for young people based in her early
experiences on the American frontier. Born in the state of Wiscosin in 1867, she or her family were rugged pioneers.
Seeking better farm land, they went by covered wagon to Missouri in 1869, then on to Kansas the next year, return to
Wisconsin in 1871, and travelling on to Minnesota and Lowa before settling permanently in South Dakota in 1879. Because
off this continuing moving, Wilder's early education took place sporadically in a succession of one-room schools. From age
thirteen to sixteen she attended a school more regularly although she never graduated.
At the age of eighteen, she married Almanzo James Wilder. They bought the small farm in the Ozarks, where they
remained for the rest of their live. Their only daughter, Rose, who had become a nationally known journalist, encouraged
her mother to write. Serving like agent and editor, Rose negotiated with Harper's to publish her mother's first book, Little
House on the Big Woods. Seven more books followed, each chronicling her early life on the plains. Written from the
perspective of a child, they have remained popular to young readers from many nations. Twenty years after her death in
1957, more than 20 million copies had been sold, and they had been translated into fourteen languages. In 1974, a
weekly television series, "Little House on the Prairie ", was produced based on the stories from the Wilder books.

Regrets

Most of us are always forgetting important date, apart to the lucky few who are blessed with a good memory or
the ability to organize themselve so they don't forget importance obligations. How many times have we all said, "I wish I
had remembered!" How often have we offended people by failing to remember their birthdays or name days?
Although they say it doesn't matter, we know, deep down, that we have hurt their feelings. We can always try to
make it up to them next time but unfortunately the damage has been done and our relationship with that person can
never quite be the same again.
In the other hand, we sometimes do too much for someone else because we want to please them and then feel
we have damaged our own interests in doing so. When friends are involved we may find it difficulty to say "no" when
they ask us to do them a favour, but true friend should mean that we can say "no" without risk to relationship.

Hầu hết chúng ta luôn luôn quên ngày quan trọng, ngoài số ít may mắn, những người được may mắn có một trí nhớ tốt, khả năng tổ chức themselve để họ không quên
nghĩa vụ quan trọng. Đã bao nhiêu lần tất cả chúng ta nói, "tôi muốn tôi đã nhớ!" Thường có những người bị xúc phạm không nhớ ngày sinh nhật của mình hoặc tên?

Mặc dù họ nói rằng nó không quan trọng, chúng ta biết, sâu xuống, mà chúng tôi đã làm tổn thương cảm xúc của mình. Chúng tôi luôn luôn có thể cố gắng để làm cho nó

Advertising has come into existence for the beginning of period when people did not use the barter system, but
bought and sold. Before the inventions of newspapers, radio and television, merchant and salesmen used to shout or
singing about things that they were selling. Those who were hired to advertise things as that were called criers. They
even used musical instruments when crying about their wares. Today, some vendors still do so.
Nowadays, newspaper and magazines are full off advertisements which look attraction and sound interesting.
There is no channel on T.V or on the radio without advertisement. Along the streets posters are installed for advertising
with many eye-catching pictures. In the store windows, goods at all kinds are displayed and available for every taste.
Computers have become the most modern device for advertising. Customers even can buy things on using the internet.

It is very importance to have healthy teeth. Good teeth helps us to chew our food. They also help us to look nice.
How does a teeth go bad? The decay begins in little crack in the enamel covering of the tooth. This happens after germs
and bits of food have collected there then the decay slowly spreads onside the tooth. Eventually, poison goes into the
blood, and we may feel quite ill.
How can we keep our teeth healthy? Firstly, we ought to visit our dentist twice a year. He can fill the small holes in
our teeth before they destroy the teeth. He can examine our teeth checking that they are growing in the right way.
Unfortunately, many people wait until they have toothache before they see the dentist. Secondly, we should brush our
teeth with a toothbrush and fluoride toothpaste at least twice a day - once after breakfast and once before we go to bed.
We can also use wooden toothpicks to clean between our teeth after a meal. Third, we should eat food that is good for our
teeth and our body: milk, cheese, fish, brown bread, potatoes, red rice, raw vegetables and fresh fruit. Chocolate, sweets,
biscuits and cakes are bad, especial when we eat them between meals. They are harmful because they stick to our teeth
and caused decay.

THE OLYMPICS
The word 'Olympics' comes from the name of a town Olympia in Greece, where the ancient Olympic Games were
always hold. The first recorded Olympic Games were held in 776 B.C.; the Games took place every four year after that
date until they were abolished by a Roman Emperor on A.D. 394. It was not until 1875, when archeologists discovered the
ruins of the Olympic Stadium in Greece, that interest in the Games were renewed. Baron Pierre de Coubertin, a French
scholar and educator, proposed that the Games should be revived like an international competition to encourage both
sport and world peace. The first modern Olympic Games were held in Athens in 1896. As their classical predecessors, the
athletes were men only; women were admitted to the Games in 1900. For that time, the Games have been held at fouryear in intervals as in ancient Greece. However, Pierre de Coubertin's dream of world peace has not been realized. The
Two World Wars prevented those of 1916, 1940, and 1944 from being held.
The Olympic Games have been confined to amateur athletes despite few recent exceptions. There are pressures on the
Olympic authorities to admit other professionals to the Games. Such a step would damage the entire concept to the
Olympics. The following words appear on the Scoreboard in every Olympic. opening: "The most important thing is not to
win but to take part." In contrast, the aim of every professional is to win.

A greatest impediment to free intercourse between nations is neither distance or the difference of mental habits, nor the
opposition of national interests; it is simply the imperfect manner in that languages are usually acquired, and the lazy
contentment of mankind to a low degree of attainment in a foreign tongue, when a much higher degree of attainment
would be necessary with any efficient interchange of ideas. It seems probable that much of the future happiness of
humanity will depend upon a determination to learn foreign languages more thoroughly. Foreigners do not open their mind
to one who blunders about theirs meanings - their confidence is only to be won by a demonstration of something like
equality in intelligent, and nobody can give proofof this unless he has the means of doing his thoughts intelligible, and
even of assuming, when the occasion presents themselve, some what bold and authoritative tone.

Ever since humans have inhabited a earth, they have made use of various forms of communicate. Generally, this
expression of thoughts and feelings have been in the form of oral speech. When there is a language barrier,
communication is accomplished through sign language in that motions stand for letters, words, and ideas. Tourists, the
deaf, and the mutes have had to resort to this form of expression. Many of these symbol of the whole words are very
picturesque and exact and can be used internationally, spelling, however, cannot.
Body language transmit ideas or thoughts by certain actions, either intentionally nor unintentionally. A wink can be a
way of flirting or indicating that the party is only joking. A nod signifies approval, while shaking the head indicates a
negative reaction.
Others forms of nonlinguistic language can be found in Braille (a system of raised dots read with the fingertips),
signal flags, Morse code, and smoke signals. Road maps and picture signs also guide, warm, and instruct people.
While verbalization is most common form of language, other systems and technique also express human thoughts
and feelings.

The loss of the jobs and persistent unemployment in the industrial countries are due mainly to changes in technology. It is thought
to be misleading to blame job losses on the shift of corporations from the industrial country to the third World.
The present technological developments has been compared to a Third Industrial Revolution. The first coming in the 19 th century,
was characterized by the steam engine and the use of coal. In the 1920 the second emerged with the use of oil and the electro dynamo.
The third, the present one, is driven by computers, biotechnology and informations technology.
However, there can be seen weaknesses in a newest of industrial revolutions. The technology is advancing so fast and productivity
is rising so fast which we are left with a big problem.. Because of the loss in jobs, caused largely by this new, technology, there will not
be enough people with money to buy all these product.

Technology as definitely enhanced our standard for living, even our quality of life. But as the capacity to produce expands and the
lack of purchasing power and consequent demand diminish, there can be overproduction and recession, and what happens to our
standard of living?

Deaf people can not sounds. How do they “hear” words and talk ? Deaf people use American Sign Language (A.S.L). They talk with their
hand. Sometimes two deaf people talk to each others. They both use A.S.L. Sometimes a person whose can hear interprets for deaf

people. The person listens to someone talk, and then he or she makes hand signs. There are two kind of sign language. One kind has a
sign for every letter in the alphabet. The person who spells every words. This is a finger spell. The other kind has a sign for every word.
There are about 5000 of these signs. They are signs for verbs, things and ideas. Some of these signs are very easily, for example, eat,
milk, and house. You can see what you mean. Others are more difficult, for example, star, egg, or week. People ffrom any country can
learn A.S.L . They use signs, not words, so they can understand people from other country. A.S.L is almost like a dance. The whole body

It is not true which the British talk about the weather more than some other nations. In many parts of the world
the weather holds just as much fascination. Part of fascination arises because of the weather in many parts of the world is
very difficult to forecast. Because Britian is an island sandwiched among a large continient and a large ocean, slight
changes in direction of winds in the Atlantic or movements in areas of high or low pressure can make a major different to
our weather.
Most of the time our weather is remarkable. But the last few years weather patterns have been causing so much
trouble that it raises the question is the weather changing to such an extent that it amounts to a change on the climate ?
It is a question that it is very difficulty to answer. The daily and weekly variations in weather is so great that it
takes years of careful measurement to detect changes in the average weather for year to year, and to detect changes in
the climate involves the worldwide application of a whole number of scientific investigation.
Howere, looking up the distant past and estimating what may happen in the future based on theoretical
possibilities, it seems there are second possibilities. The world could be slipping back towards another ice age. But in the
shorter term what man is doing may well lead for a heating up the planet which could delay, if not prevent, any
forthcoming ice age.
It is suddenly and unexpected weather which made people wonder what is happening to our climate-like the oncein-a-lifetime experience of the vicious storm which swept southern England in Autumn 1987. The southern states of the
USA are used to such storms, the southern part of Britain isn’t. And when literally millions of trees were uprooted and
millions of pounds worth of damage was done to houses, farms and business, people wondered just what was going on. It
was probably the worst storm in south-East Britain for some 300 years.

If you were to stop people on the street and asked them to name a ship which had been sunk, it is likely that nearly all of
them would say the Titanic. For the sinking of the Titanic was, if not the most tragic, certain the most famous sea disaster
in the history of ocean travel.
The Titanic was built like a luxury liner, intended to be the fastest in the world, and a great deal of publicity had
surrounded it. The last point probably explains why so much important people from all walks of the life were on the boat
when it went down.
The Titanic was on its maiden voyage to American in 1912 when it struck an iceberg and sink. Of its 2,300 passengers,
more than two-thirds were drowned. Because of the Titanic was thought to be virtual unsinkable, no one was prepared for
the tragedy. There was total panic as very a few of the passengers had bothered to learn the necessary drill in the event of
trouble. There was severe short of lifeboats and those that were launched were still half-empty. The one point of calm was
to be found in the ballroom which the band carried on playing right to the end.
What makes the sink of the Titanic even more tragic is the fact that warnings of icebergs had been sent, yet the liner was
still continuing at full speed. In addition one ship was only ten miles away but did not received the distress signal.
One good thing did, however, result from disaster. The whole question of safety at sea was looked at, resulting in much
better satety measures, including stricter lifeboat regulations and the establish of an iceberg patrol.

In recent years, scientific and technological developments have drastically changed human life on our planet, as well as
our views both of ourselves as individuals in society and of the universe as a whole. Maybe one of the most profound
developments of the last decate is the discovery of recombinant DNA technology, which allows scientists to introduce
genetic material (or genes) from one organism into another. In its simplest form, the technology requires the isolation of a
piece of DNA, either directly from the DNA of the organism understudy or artificially synthesized from an RNA template, by
using a viral enzyme called reverse transcriptase. The piece of DNA is then ligated to a fragment of bacterial DNA which
has the capacity to replicate itself independently. The recombinant molecule thus produced can be introduced into the
common intestinal bacterium Escherishchia coli, which can be grown in very large amounts in synthetic media. Under
proper conditions, the foreign gene will not only replicate in the bacteria, but also express itself, through the process of
transcription and translation, to give rise to large amounts of the specific protein coded by the foreign gene.
The technology has already been successfully applied to the production of several therapeutically important biomolecules,
such as insulin, interferon, and growth hormones. Many other important applications are under detailed investigation in

laboratories throughout the world.

WILD STORIES
A staple of newspapers everywhere are those stories that run under the "Man Bites Dog" headline. From France comes the
story of an attack on an old man near Calais carried out by a swarm of bees. The scenario might have pleased Hitchcock.
The victim was sunning himself in his garden at the time. The firemen were called but were driven back into their van by
the ferocity of the insects. After 45 minutes someone arrived with protective clothing and insecticide. By then the man
sitting in the deck chair was dead, covered in hundreds of stings, most of them on his eyelids.
The French liked the story from London about grafting a pig's kidneys on to a human patient. They went for the animal
rights angle. They like the idea of putting a security ring round the hospital to repel people who are intent on rescuing the
pig from dismemberment. From London, too, came the story of:the brown paper parcel in London's main parcel sorting
office, a parcel which moved. Packages do not normally move very quickly through the post office at the best of times, but
this one was definitely frisky. A lady customs officer was summoned to X-ray the package. The X-ray revealed a poisonous
reptile called a gila monster wrapped in a sock. The subsequent police trail led to a salesman in Hampshire whose back
bedroom was filled with rattlesnakes, lethal lizards, snapping turtles and a python, most of which he had sent himself
through the post.

CORRECTED MISTAKES
An animal story which made the British papers a couple of years ago was the report that staff at Stockholm's Skansen Park
zoo had raffled the remains of a favourite bear cub, and that the winners had taken home a joint for the pot. "How could
they? How can staff give a cub a name, look after her for a year or two, and then end up sneaking her on to the dinner
table," asked Malin Bergman, 15, winner of a national competition to pick a name for the cub, called Molly. A Swedish
newspaper columnist said she had been swamped with calls from readers in tears. She said: "It sounds bizarre to eat up
an animal that has been given a name and a national identity. Dog meat is popular in China and Korea, but people there
don't eat Oscar the family chow." The superintendent of the zoo was quoted as saying that while people did not like to see
"teddy bears" eaten, "it's worse to destroy meat in a world that hungers."

The whole business of eating dog could be the answer to a crisis in Britain's cities. The country is suffering from half a
million stray dogs. 1,000 are destroyed every day. In one small town alone, £100,000 is spent each year catching stray
dogs. Terry Singh, the local dog-catcher, admits grimly: "Wee are chasing .our tails. In a town of half a million people, we
have 50,000 stray dogs." In Britain, seven million dogs bite a quarter of a million people a year, at a cost of six million for
casualty treatment. They attack 10,000 farm animals, cause 50,000 road accidents, and require three million to be spent
on kennelling and destruction.
Mr Singh says: "In my first year we had 775 complaints. That was 10 years ago. Our recent figures show we are dealing
with six thousand dogs a year. Everywhere you look in the town, on any patch of grass or street corner, you will see at
least one stray dog. We even get packs of dogs loose on housing estates. Dog attacks have increased. The craze of the
moment is for owning Rottweilers and Dobermans."The city has two main dog kennels run by the RSPCA. At one, two and
a half thousand dogs are destroyed every year, put down with an injection of Pentobarbitone.
Considering what has been going on down at the farm, it may be safer to eat British dog rather than British beef. It
appears that British farmers have been feeding their cattle on processed artificial food which includes sheep carcasses
infected with a brain disease called scrapie. This practice was banned in 1988, but it appears that the disease has already
been transmitted to British cattle. The big question has been, if the disease can be transmitted from sheep to cattle, surely
it follows that it can be transmitted from cattle to people.
The infection appears to be present in the immune system and in the brain and nervous system. Evidence shows that there
is a link between brain disease and the eating of sheep's heads in the Middle East. In one instance, there is a high
incidence of Creutzfeldt-Jakob disease, a degenerative disease of the brain, among Libyan Jews, who eat sheep's eyes.
According to one researcher: "Steak has very little nervous tissue in it, and it is very unlikely to pass on disease. But
nothing would induce me to eat other parts of the animal." So it's goodbye to cervelle au beurre noisette and amourettes a
la Tosca. Life gets duller all the time.

A new British medical instrument is about to change dramatically out ability to recognize diseases hidden inside the body.
It is called the magnetic scanner, and it gives information about the body which current machines, such as the brain
scanner and the more recent body scanner, cannot provide. And unlike existing machines, the new machine does not use
X-ray radiation waves, which make it much safer for patients. Unlike existing scanners, a magnetic scanner can show the
side or the back of a suspect part of the body. Used on, for example, a lung with a suspected damage, it can turn the
image of the lung to give a series of different views. The scanner actually examines every side of the lung. When
examining the softer part of the body with existing scanners, doctors fi-equently have to use a contrast medium to make a

muscular organ show up to X-ray waves, the usual ' contrast medium" given to patients before a stomach X- ray scan
takes place is harmless, but for some brain scans so that it passes into the brain, this is unpleasant and painful and it can
be dangerous. The magnetic scanner needs no 'contrast medium". The new machine can also see in greater detail than
ever before. Growths of all kinds show up clearly on tb-e brain and so do the dead patches which are the signs of the
diseases, multiple sclerosis. Until now patients complaining of double vision or inability to control their muscles from time
to time could be suffering from multiple sclerosis or, equally, from some much more easily cured disease and a brain
scanner could not distinguish between these with certainty. The doctor can now definitely say whether or not cancer or
multiple sclerosis is present. Previously, these diseases have been missed and patients have been given false information
about their health. The technique is still improving with great speed: pictures produced a couple of years ago look very
simple compared with those of today

Several hundred million year ago, plants similar modem ferns covered vast stretches of the land. Some were large as trees,
with giant fronds bunched at the top of trunks as straight as pillars. Others were the size of bushes and formed thickets of
undergrowth. Still others lived in the shade of giant club mosses and horsetails along the edges of swampy lagoons where
giant amphibians swam.
A great amount of these plants were true ferns, reproducing themselves without fruits or seeds. Other had only the

appearance of ferns. Their leaves had ogans of sexual reproduction and produced seeds. Although their 'flowers" did not
have corollas, these false ferns (today comletely extinct) ushered in the era of flowering plants. Traces of these flora of the
earliest times have preserved in the form of fossils. So traces are most common found in shale and sandstone rocks
wedged between coal beds.
Today only tropical forests bear living proof of the ancient great of ferns. The species that grow there is no longer those of
the Carboniferous period, but their variety and vast numbers, and the great size of some remind us about the time when
ferns ruled the plant kingdom.

Independence Day in the United States is observed every year on the Fourth of July. Today, for most communities
throughout the nation, the traditional celebration includes parades down the main streets, pinics with Mot dogs and
lemonade, and, of course, a fireworks display at night. In some towns across the country, however, special events are
planned in honor of the annual occasion. In Bristol, Rhode island, fire engine teams from communities throughout New
England compete in a contest to squirt water from the fire hoses. Flagstaff, Arizona hosts a huge three-day powwow,
including a rodeo, for twenty Native American tribes. The annual Eskimo games with traditional kayak races are held in
Kotzebue, Alaska. Two auto races are always scheduled for the Fourth, including a four-hundred-mile stock car event at
the Daytona international Speedway in Daytona, Florida, and an annual auto race up to the fourteen thousand- foot
precipice at Pike's Peak in Colorado.
Several small towns celebrate in other unique ways. Hannibal, Missouri, the hometown of Mark Twain, invites the children
to participate in a fence-painting contest, reenacting a scene from Twain's novel Tom Sawyer. Lititz, Pennsylvania
congregates in the Lititz Springs Park to light thousands of candles and arrange them in various shapes and images. In
Ontario, California, the townspeople combine the traditional with the unusual by setting up tables along Euclid Avenue for
what they describe as ' the biggest pinic table in the world." In this way, every one in town has a front-row seat for the

two-mile parade.

Ever since the first news photo was made 140 years ago - a panoramic view of Hamburg after the big fire of 1842 - photojournalism has
excelled in depicting horrors. The pleasant, the ordinary rarely make the news.
Given the demand for sensational photographs, everyone regards press photographers as an overbearing lot, as mercenaries in the pay
of public curiosity; ever in pursuit, flashgun at the ready, of the unsuspecting victim. Armed to the teeth with the tools of their trade,
they elbow their way through the crowd,.trampling on the gardens of the famous, jamming their feet into half-closed doors and lying in
wait for the widow before the still-open grave. But are press photographers really only cold "glass eyewitnesses"? Certainly, in talking to
top photographers, the dilemma of this profession comes out: how can artistic senskivity be reconciled with the necessarily tough job of
the reporter?
Philip Jones Griffiths, despite having produced the most terrifying book of photographs on the Vietnam War ever seen and having been a
reporter for twenty years, still has difficulty in photographing people in the street: "If you are sensitive enough to see unusual images,
you are also sensitive and shy when you have to stick your lens into some stranger's face." Griffiths now knows instinctively how far he
can go on each occasion. He has learned to interpret the body language of the people around him and achieves what he wants by gentle
persuasion: "So far I have never been attacked. No one has ever thrown me out."
Volker Hinz. on the staff of the magazine Stern, is regarded by his colleagues as a tough nut who never takes no for an answer. Yet he
says for himself, "Deep down, I'm a shy person. It costs me a great deal of psychological effort to have to elbow my way through a

crowd of photographers to get to the front. But what can you do? I have to get the best picture at all costs." Hinz also knows that cold
routine can be dangerous. "I have to work up enthusiasm for each new job. I have to become more open and sensitive. I have to be
prepared for the unexpected."
Being up close - that is the curse but also the strength of the photographic medium. A reporter can do his writing from a safe distance
behind the lines, gather information second hand or even by sorting through files. A photographer has no choice; he can't take photos
from behind a desk, he has to be right where the action is. This requires a special temperament.
"Occasionally photographers are little crazy, and almost always they are obsessed," writes Time magazine in a story on photojournalism.

Good photographers seldom fit the corporate mould. They can be a nuisance; most are emotional. Many of them are politically
motivated and have a soft spot for the downtrodden, since everyday they have to cross the line towards poverty, sickness, mischief or
simply towards the everyday lives of the common mass. Photography is blue collar work. It means dragging heavy equipment around,
rain or shine, in heat and cold; it means hanging out at street comers - certainly not a noble profession.

Although most universities in the United States arre on the semester system, which offers classes on the fall and spring,
some schools observe a quarter system comprised of fall, winter, spring and summer quarters. The academic year,
September to June, is divided into three quarters of eleven weeks each beginning in March, September, January; the
Summer quarter. June to August, is composed of shorter sessions of varying length. There are several advantages and
disadvantages to the quarter system. On the plus side, students who wish to complete their degrees in less than the
customary four years may take advantage of the opportunity to study year round by enrolling in all four quarters. In
addition, although most students begin their programs in the fall quarter, they may enter at the beginning of any other
quarters. Finally, since the physical facilities are kept in operation year round, the resources are used efficiently to serve
the greatest number of students. But there are several disadvantges as well. Many faculties complain that the eleven-week
term is simply not long enough for them to cover the material required by most college courses. Students also find it
difficult to complete the assignements in such a short period of time. In order to combine the advantages of the quarter
system with those of semester system, some colleges and universities have instituted a three-term trimester. In fourteen
weeks, faculties and students have more time to cover material and finish course requirements, but the additional term
provides more options for admission during the year and accelerates rhe degree program for those students who wish to
graduate early.

KEEPING YOUR DISTANCE
Personal space is a term that refers to the distance we like to
keep between ourselves and other people. When someone we do not
know well gets too close that we usually begin to feel uncomfortable.
If such a business colleague comes closer than 1.2 meters, the most
common response is to move away. Some interesting studies have
been done in libraries. If strangers will come too close, many people
get up and leave the building, others use to different methods such as
turning their back on the intruder. Living in cities has made people to
develop new skills for dealing with situations where they are very
close to strangers. Most people on so crowded trains try not to look at
strangers; they avoid skin contract, and apologize if hands touch by a
mistake. People use newspapers as a barrier between themselves and
other people, and if they do not have one, they stare into the distance,
making sure they are not looking into anyone’s eyes.

Large animals inhabit the desert have evolved adaptations for reducing the effects of
extreme hot. One adaptation is to be light in color, and to reflect the Sun's rays. Desert mammals
also depart from the normal mammalian practice of maintaining a constantly body temperature.
Instead of try to keep down the body temperature inside the body, what would involve the
expenditure of water and energy, desert mammals allow their temperatures rise to what would
normally be fever height, and temperatures as high as 46 degree Celsius have been measured in
Grant's gazelles. The overheated body cools down during the cold desert night, and indeed the
temperature may fall unusual low by dawn, as low as 34 degrees Celsius in the camel. This is a
advantage since the heat of the first few hours of daylight absorb in warming up the body.
