Read the following passage and mark the letter A, B, C or D on your answer
sheet to indicate the correct

answer to each of the following questions
BÀI SỐ 1

Animation traditionally is done by hand-drawing or painting successive frames of an
object, each slightly different than the preceding frame. In computer animation, although
the computer may be the one to draw the different frames, in most cases the artist will
draw the beginning and ending frames and the computer will produce the drawings
between the first and the last drawing. This is generally referred to as computer-assisted
animation, because the computer is more of a helper than an originator.
In full computer animation, complex mathematical formulas are used to produce the
final sequence of pictures. These formulas operate on extensive databases of numbers
that define the objects in the pictures as they exist in mathematical space. The database
consists of endpoints, and color and intensity information. Highly trained professionals
are needed to produce such effects because animation that obtains high degrees of realism
involves computer techniques for three-dimensional transformation, shading, and
curvatures.
High-tech computer animation for film involves very expensive computer systems
along with special color terminals or frame buffers. The frame buffer is nothing more
than a giant image memory for viewing a single frame. It temporarily holds the image for
display on the screen.
A camera can be used to film directly from the computer's display screen, but for the
highest quality images possible, expensive film recorders are used. The computer
computes the positions and colors for the figures in the picture, and sends this
information to the recorder, which captures it on film. Sometimes, however, the images
are stored on a large magnetic disk before being sent to the recorder. Once this process is
completed, it is repeated for the next frame. When the entire sequence has been recorded
on the film, the film must be developed before the animation can be viewed. If the entire
sequence does not seem right, the motions must be corrected, recomputed, redisplayed,

and rerecorded. This approach can be very expensive and time consuming. Often,
computer-animation companies first do motion tests with simple computer-generated line
drawings before selling their computers to the task of calculating the high-resolution,
realistic-looking images.

In the world today, particularly in the two most industrialized areas, North America
and Europe, recycling is big news. People are talking about it, practicing it, and
discovering new ways to be sensitive the environment. Recycling means finding ways
to used products a second time. The motto of the recycling movement is "Reduce,
Reuse, Recycle".
The first step is to reduce garbage. In stores, a shopper has to buy products in
blister packs, boxes and expensive plastic wrappings. A hamburger from a fast food
restaurant comes in lots of packaging: usually paper, a box, and a bag. All that
packaging is wasted resources. People should try to buy things that are wrapped
simply, and to reuse cups and utensils. Another way to reduce waste is to buy
high-quality products. When low quality appliances break, many customers throw
them away and buy new ones - a loss of more resources and more energy. For
example, if a customer buys a high-quality appliance that can be easily repaired, the
manufacturer receives an important message. In the same way, if a customer chooses
a product with less packaging, that customer sends an important message to the
manufacturers. To reduce garbage, the throwaway must stop.
The second step is to reuse. It is better to buy juices and soft drinks in returnable
bottles. After customers empty the bottles, they return them to the store. The
manufacturers of the drinks collect the bottles, wash them, and then fill them again.
The energy that is necessary to make new bottles is saved. In some parts of the world,

returning bottles for money is a common practice. In those places, the garbage dumps
have relatively little glass and plastic from throwaway bottles.
The third step is being environmentally sensitive is to recycle. Spent motor oil can be
cleaned and used again. Aluminum cans are expensive to make. It takes the same
amount of energy to make one aluminum can as it does to run a color TV set for three
hours. When people collect and recycle aluminum (for new cans), they help save one
of the world's precious resources.


Question 8: Which area is considered one of the most industrialized?
A. South America

B. Middle East

C. Europe

D. Asia

Question 9: What does the word “sensitive” in line 2 means?
A. cautious

B. logical

Question 11: It is a waste when customers buy low-quality products because
________
A. they have to be repaired many times.

B. they will soon throw them away

C. customers always change their area

D. they are very cheap

Question 12: What is the topic of the passage?
A. How to live sensitively to the environment.
B. How to reduce garbage disposal.
C. What is involved in the recycling movement.
D. What people understand the term “recycle”
Question 13: People can do the following to reduce waste EXCEPT ________

A survey is a study, generally in the form of an interview or a questionnaire, which
provides information concerning how people think and act. In the United States, the
best-known surveys are the Gallup poll and the Harris poll. As anyone who watches
the news during presidential campaigns knows, these polls have become an important
part of political life in the United States.
North Americans are familiar with the many "person on the street"
interviews on local television news shows. While such interviews can be highly
entertaining, they are not necessarily an accurate indication of public opinion.
First, they reflect the opinions of only those people who appear at a certain location.
Thus, such samples can be biased in favor of commuters, middle-class shoppers, or
factory workers, depending on which area the new people select. Second, television
interviews tend to attract outgoing people who are willing to appear on the air, while
they frighten away others who may feel intimidated by a camera. A survey must be
based on a precise, representative sampling if it is to genuinely reflect a broad range
of the population.
In preparing to conduct a survey, sociologists must exercise great care
in the wording of questions. An effective survey question must be simple and clear
enough for people to understand it. It must also be specific enough so that there are no
problems in interpreting the results. Even questions that are less structured must be
carefully phrased in order to elicit the type of information desired. Surveys can
be indispensable sources of information, but only if the sampling is done properly and
the questions are worded accurately.

There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer
can obtain a high response rate because people find it more difficult to turn down a
personal request for an interview than to throw away a written questionnaire.
In addition, an interviewer can go beyond written questions and probe
for a subject's underlying feelings and reasons. However, questionnaires have the
advantage of being cheaper and more consistent.

Question 15: According to the passage, one advantage of live interviews over
questionnaires is that live interviews _________.


A. minimize the influence of the researcher

B. are easier to interpret

C. costless

D. can produce more information

Question 16: The word “they” refers to ________.
A. interviews

B. opinions

C. news shows

D.

North

Americans
Question 17: Which word is given definition in the text?
A. sampling

B. poll

C. survey

D. interview

Question 18: According to paragraph 3, which of the following is most important for
an effective survey?
A. A sociologist who is able to interpret the results
B. Carefully worded questions
C. An interviewer’s ability to measure respondents’ feelings
D. A high number of respondents
Question 19: What does the passage mainly discuss?
A. The principles of conducting surveys
B. The importance of polls in American political life
C. Problems associated with interpreting surveys

Basic to any understanding of Canada in the 20 years after the Second World War is
the country’s impressive population growth. For every three Canadians in 1945, there
were over five in 1966. In September 1966 Canada’s population passed the 20 million
mark. Most of his surging growth came from natural increase. The depression of the
1930’s and the war had held back marriages, and the catching-up process began after
1945. The baby boom continued through the decade of the 1950s, producing a
population increase of nearly fifteen percent in the five years from 1951 to 1956. This
rate of increase had been exceeded only once before settle. Undoubtedly, the good

economic conditions of the 1950’s supported a growth in the population, but the
expansion also derived from a trend toward earlier marriages and an increase in the
average size of families. In 1957 the Canadian birth rate stood at 28 per thousand, one
of the highest in the world.
After the peak year of 1957, the birth rate in Canada began to decline. It
continued falling until in 1966 it stood at the lowest level in 25 years. Partly this
decline reflected the low level of births during the depression and the war, but it was
also caused by changes in Canadian society. Young people were staying at school
longer; more women were working; young married couples were buying automobiles
or houses before starting families; rising living standards were cutting down the size
of families. It appeared that Canada was once more falling in step with the trend
toward smaller families that had occurred all through the Western world since the
time of the Industrial Revolution.
Although the growth in Canada’s population had slowed down by
1966 (the increase in the first half of the 1960’s was only nine percent), another large
population wave was coming over the horizon. It would be composed of the children
who were born during the period of the high birth rate prior to 1957.
Question 20: What does the passage mainly discuss?
A. Educational changes in Canadian society
War

B. Canada during the Second World

C. Population trends in postwar Canada

D. Standards of

living in Canada.

Question 21: The word “five” in bold refers to
A. Canadians

B. years

C. decades

D. marriages

Question 22: The word “surging” in bold is closest in meaning to
A. new

D. surprising

Question 23: The author suggests that in Canada during the 1950’s
A. the urban population decreased rapidly

B. fewer people married

C. economic conditions were poor

D. the birth rate was very high

Question 24: The word “trend” in bold is closest in meaning to:

A. tendency

B. aim

C. growth

D. directive

Question 25: The author mention all of the following as causes of declines in
population growth after 1957
EXCEPT
A. people being better educated

B. people getting married earlier

C. better standards of living

D. couples buying houses

Question 26: It can be inferred from the passage that before the Industrial Revolution
A. families were larger

Shyness may not seem to be a serious complaint, but for some who suffer from it, it
can become unbearable. Even talking to a small group of people you know can seem
like an ordeal - it can feel as if you’ve been asked to give a speech on a topic you know
very little about to a number of experts. You start to feel hot and shaky, your heart beats
faster, your knees feel weak, you begin to stutter and the whole experience seems to last
forever.
The fact of the matter is that shyness is something we often recognize in others:
blushing is one of the more visible signs, for example. Yet we do not judge someone
harshly because of this. But shyness does mean you are harder to approach, so you
become more isolated. As one shy person put it, “It’s like being in a prison, and it’s very
hard to break out.”
Experts on the subject have come up with various possible solutions, and one has
been singled out as being the key to success, namely, finding an interest in common
with other people. Spending a lot of time on the sidelines watching other people and
envying them because they are much more outgoing doesn’t help; remembering that


some of the people you envy most are probably shy themselves. The secret is how you
deal with it. And experts have come up with four things you can do today to help.
Firstly, you can start by listening to other people. You will find yourself getting
interested in what they’re talking about and asking questions, and before you know it,
you’ll be having a conversation. Secondly, you could try asking neighbors if you can

walk their dog. Like children, pets can be excellent icebreakers for conversations with
passers-by. Thirdly, try joining a class to learn something like tap-dancing or flamenco,
where people are likely to laugh a lot. You’ll feel relaxed, and also you’ll be much too
busy concentrating on what you are doing to feel shy. Lastly, try telling yourself that it
doesn’t matter if you say or do something silly. Most people make a fool of themselves
every so often, and it’s not the end of the world if you do.
Question 28. One of the symptoms of shyness in a stressful situation is ________
A. sweating a lot.

B. an increased heart rate.

C. pain in the knees.

D. excessive talkativeness.

Question 29. Why do shy people become more reserved?
A. Their social unease makes them more difficult to talk to.
B. They see that others are shy too.
C. Other people lack the patience to talk to them.
D. They dread being judged by others.
Question 30. The word “blushing” in paragraph 2 is closest in meaning to ________.
A. going green

B. going red

C. smiling

D. sweating

Question 31. What do experts believe is the most essential measure to be taken?

A. Studying others’ behaviour in social situations.
B. Discovering shared interests with others.
C. Comparing yourself to other people.
D. Finding out what makes other people shy.
Question 32. How can listening to others prove helpful in combating shyness?


A. You develop useful psychological skills.
B. It’s the first step to getting into conversation.
C. People will see you care about their interests.
D. It’s a visible sign of becoming less shy.

Every drop of water in the ocean, even in the deepest parts, responds to the forces
that create the tides. No other force that affects the sea is so strong. Compared with the
tides, the waves created by the wind are surface movements felt no more than a hundred
fathoms below the surface. The currents also seldom involve more than the upper
several hundred fathoms despite their impressive sweep.
The tides are a response of the waters of the ocean to the pull of the Moon and the
more distant Sun. In theory, there is a gravitational attraction between the water and
even the outermost star of the universe. In reality, however, the pull of remote stars is so
slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun.
Just as the Moon rises later each day by fifty minutes, on the average, so, in most
places, the time of high tide is correspondingly later each day. And as the Moon waxes
and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are
strongest when the Moon is a sliver in the sky, and when it is full. These are the highest
flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At
these times the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly
bodies is added together to bring the water high on the beaches, to send its surf upward
against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the
quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular

configuration and the pull of the Sun and Moon are opposed, the moderate tidal
movements called neap tides occur. Then the difference between high and low water is
less than at any other time during the month.
Question 33. What is the main point of the first paragraph?
A. The waves created by ocean currents are very large.
B. Despite the strength of the wind, it only moves surface water.


C. Deep ocean water is seldom affected by forces that move water.
D. The tides are the most powerful force to affect the movement of ocean water.
Question 34. The word “felt” in line 3 is closest in meaning to
A. based

B. dropped

C. detected

D. explored

Question 35. The words “In reality” in line 8 are closest in meaning to
A. surprisingly

B. actually

C. characteristically

D. similarly

Question 36. It can be inferred from the passage that the most important factor in
determining how much gravitational effect one object in space has on the tides is

A. size

B. distance

C. temperature

D. density

Question 37 The word “correspondingly” in line 11 is closest in meaning to
A. unpredictably

B. interestingly

C. similarly

D. unusually

Question 38. What is the cause of spring tides?
A. Seasonal changes in the weather
B. The gravitational pull of the Sun and the Moon when nearly in line with the Earth
C. The Earth's movement around the Sun
D. The triangular arrangement of the Earth, Sun, and Moon

Centuries ago, man discovered that removing moisture from food helped to
preserve it, and that the easiest way to do this was to expose the food to sun and wind.
In this way the North American Indians produced pemmican (dried meat ground into
powder and made into cakes), the Scandinavians made stock fish and the Arabs dried
dates and apricots.
All foods contain water - cabbage and other leaf vegetables contain as much as
93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything

from 80% to 60% depending on how fatty it is. If this water is removed, the activity
of the bacteria which cause food to go bad is checked.


Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean
countries, and also in California, South Africa and Australia. The methods used vary,
but in general the fruit is spread out on trays in drying yards in the hot sun. In order to
prevent darkening, pears, peaches and apricots are exposed to the fumes of burning
sulphur before drying. Plums for making prunes, and certain varieties of grapes for
making raisins and currants, are dipped in an alkaline solution in order to crack the
skins of the fruit slightly and remove their wax coating, so increasing the rate of
drying.
Nowadays most foods are dried mechanically; the conventional method of such
dehydration is to put food in chambers through which hot air is blown at temperatures
of about 110°C at entry to about 45°C at exit. This is the usual method for drying such
things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them
over a heated horizontal steel cylinder or by spraying them into a chamber through
which a current of hot air passes. In the first case, the dried material is scraped off the
roller as a thin film which is then broken up into small, though still relatively coarse
flakes. In the second process it falls to the bottom of the chamber as a fine powder.
Where recognizable pieces of meat and vegetables are required, as in soup, the
ingredients are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans
or frozen, and they do not need to be stored in special conditions. For these reasons
they are invaluable to climbers, explorers and soldiers in battle, who have little
storage space. They are also popular with housewives because it takes so little time to
cook them.
Question 39: What is the main idea of the passage?
A. Mechanization of drying foods

C. Advantages of dried foods

B. Water, the main component of food

D. Different methods of drying foods.

Plants and animals will find it difficult to escape from or adjust to the effect of global
warming. Scientists have already observed shifts in the lifecycles of many plants and
animals, such as flowers blooming earlier and birds hatching earlier in the spring.
Many species have begun shifting where they live or their annual migration patterns
due to warmer temperatures. With further warming, animals will tend to migrate
toward the poles and up mountainsides toward higher elevations. Plants will also
attempt to shift their ranges, seeking new areas as old habitats grow too warm. In
many places, however, human development will prevent these shifts. Species that find
cities or farmland blocking their way north or south may become extinct. Species
living in unique ecosystems, such as those found in polar and mountaintop regions,
are especially at risk because migration to new habitats is not possible. For instance,
polar bears and marine mammals in the Arctic are already threatened by dwindling
sea ice but have nowhere farther to go. Projecting species extinction due to global
warming is extremely difficult. Some scientists have estimated that 20 to 50 percent
of species could be committed to extinction with 2 to 3 Celsius degrees of further

warming. The rate of warming, not just the magnitude, is extremely important for
plants and animals. Some species and even entire ecosystems, such as certain types of


forest, many not be able to adjust quickly enough and may disappear. Ocean
ecosystems, especially fragile ones like coral reefs, will also be affected by global
warming. Warmer ocean temperatures can cause coral to “bleach”, a state which if
prolonged will lead to the death of the coral. Scientists estimate that even 1 Celsius
degree of additional warming could lead to widespread bleaching and death of coral
reefs around the world. Also, increasing carbon dioxide in the atmosphere enters the
ocean and increases the acidity of ocean waters. This acidification further stresses
ocean ecosystems.

Long ago prehistoric man began to domesticate a number of wild plants and
animals for his own use. This not only provided a more abundant food source but also


allowed more people to live on a smaller plot of ground. We tend to forget that all
of our present – day pets, livestock, and food plants were taken from the wild and
developed into the forms we know today.
As centuries passed and human cultures evolved anf blossomed, humans
began to organise their knowledge of nature into the broad field of natural history.
One aspect of early natural history concerned the use of plants for drugs and
medicine. The early herbalists sometimes overworked their imaginations in this
respect. For example, it was widely believed that a plant or part of a plant that
resembles an internal organ would cure ailments of that organ. Thus, an extract made
from a heart-shaped leaf might be prescribled for a person suffering from

heart

problems.
Nevertheless, the overall contributions of these early observers provided the
rudiments of our present knowledge of drugs and their uses.

Question 59: What does this passage mainly discuss?
A. Cures from plants

B. The beginning of natural history

C. Prehistoric man

and Europe, recyling is big news. People are talking about it, practicing it, and

When low quality appliances break, many customers throw them away and buy new

garbage, the throwaway must stop.
The second step is to reuse. It is better to buy juices and soft drinks in returnable

manufacturers of the drinks collect the bottles, wash them, and then fill them again.
The energy that is necessary to make new bottles is saved. In some parts of the word,
returning bottles for money is a common practice. In those places, the garbage dumps

cleaned and used again. Aluminum cans are expensive to make. It takes the same
amount of energy to make one aluminum can as it does to run a color TV set for three
hours. When people collect and recycle aluminum (for new cans), they help save one
of the world’s precious resources.

Telecommuting is some form of computer communication between employees’homes
and offices. For employees whose job involve sitting at a terminal or word processor
entering data or typing reports, the location of the computer is of no consequence. If
the machine can communicate over telephone lines, when the work is completed,
employees can dial the office computer and transmit the material to theiremployer. A
recent survey in USA Today estimates that there are approximately 8,7 million
telecommuters. But although the numbers are rising annually, the trend does not
appear to be as significant as predicted when Business Week published “ The Portable
Executive” as its cover story a few years ago. Why hasn’t telecommuting become
more popular?
Clearly, change simply takes time. But in addition, there has been active
resistance on the part of many managers. These executives claim that supervising the
telecommuters in a large work force scattered across the country would be too
difficult, or, at least, systems for managing them are not yet developed, thereby
complicating the manager’s responsibilities.
It is also true that employees who are given the option of telecommuting are
reluctant to accept the opportunity. Most people feel that they need regular interaction

with a group, and many are concerned that they will not have the same consideration
for advancement if they are not more visible in the office setting. Some people feel
that even when a space in their homes is set aside as a work area, they never really get
away from the office.
Question 69: With which of the following topics is the passage primarly concerned?
A. The advantages of telecommuting.

B. A definition of telecommuting.

C. An overview of telecommuting.

D. The failure of telecommuting.

Question 70: The phrase “ of no consequence” means___________.
A. of no use

B. of no good

C. unimportant

D. . irrelevant


Question 71: The author mentions all of the following as concerns of telecommuting,
EXCEPT_______.
A. the opportunities for advancement.
B. the different system of supervision.
C. the lack of interaction with a group.

Question 72: The reason why telecommuting has not become popular is that the

employees _______.
A. need regular interaction with their families.
B. are worried aboout the promotion if they are not seen at the office.
C. feel that a work area in their home is away from the office.
D. are ignorant of telecommuting.
Question 73: When Busines Week published “ The Portable Executive”, it implied
that_________.

B. there was resistance on the part of many managers about telecommuting.
C. the trend for telecommuting was optimistic.
D. most telecommuters were satisfied with their work.

In addition to providing energy, fats have several other functions in the body.
The fat soluble vitamins, A, D, E, and K, are dissolved in fats, as their name implies.
Good sources of these vitamins have high oil or fat content, and the vitamins are
stored in the body’s fatty tissues. In the diet, fats cause food to remain longer in the
stomach, this increasing the feeling of fullness for some time after a meal is eaten.
Fats add variety, taste and texture to foods, which accounts for the popularity of fried
foods. Fatty deposits in the body have an insulating and protective value. The curves
of the human female body are due mostly to strategically located fat deposits.
Whether a certain amount of fat in the diet is essential to human health is not
definitely known. When rats are fed a fat-free diet, their growth eventually ceases,
their skin becomes inflamed and scaly, and their reproductive systems are damaged.
Two fatty acids, linoleic and acids, prevent these abnormalities and hence are called


essential fatty acids. They also are required by a number of other animals but their
roles in human beings are debatable. Most nutritionists consider linoleic fatty acid an
essential nutrient for humans.
Question 74: This passage probably appeared in which of the following?

A. A diet book

An air pollutant is defined as a compound added directly or indirectly by humans
to the atmosphere in such quantities as to affect humans, animals, vegetation, or
materials adversely. Air pollution requires a very flexible definition that permits
continuous change. When the first air pollution laws were established in England in
the fourteenth century, air pollutants were limited to compounds that could be seen or
smelled - a far cry from the extensive list of harmful substances known today. As
technology has developed and knowledge of the health aspects of various chemicals
has increased, the list of air pollutants has lengthened. In the future, even water vapor
might be considered an air pollutant under certain conditions.
Many of the more important air pollutants, such as sulfur oxides, carbon
monoxide, and nitrogen oxides, are found in nature. As the Earth developed, the
concentration of these pollutants was altered by various chemical reactions; they
became components in biogeochemical cycles. These serve as an air purification
scheme by allowing the compounds to move from the air to the water or soil. On a
global basis, nature's output of these compounds dwarfs that resulting from human
activities.
However, human production usually occurs in a localized area, such as a city. In
such a region, human output may be dominant and may temporarily overload the
natural purification scheme of the cycles. The result is an increased concentration of
noxious chemicals in the air. The concentrations at which the adverse effects appear
will be greater than the concentrations that the pollutants would have in the absence
of human activities. The actual concentration need not be large for a substance to be a
pollutant; in fact, the numerical value tells us little until we know how much of an
increase this represents over the concentration that would occur naturally in the area.
For example, sulfur dioxide has detectable health effects at 0.08 parts per million

(ppm), which is about 400 times its natural level. Carbon monoxide, however, has a
natural level of 0.1 ppm and is not usually a pollutant until its level reaches about 15
ppm.

The history of clinic nutrition, or the study of the relationship between health and how
the body takes in and utilizers food substances, can be divided into four distinct eras:
the first began in the nineteenth century and extended into the early twentieth century
when it was recognized for the first time that food contained constituents that were
essential agents. Near the end of this era, research studies demonstrated that rapid

weight loss was associated with nitrogen imbalance and could only be rectified by
providing adequate protein associate with certain foods.
The second era was initiated in the early decades of the twentieth century and
might be called "the vitamin period". Vitamins came to be recognized in foods, en
