Australia was settled by Europeans in 1788, mainly to home criminals, but with a little

independent farmers and businessmen. The settlements were not wealthy, and there
was little help available to them in need: the poor, the sick, the unemploy, and the
aged. To begin with, what little help was availably came in the form of charity:
donations of money, acommodation or medical treatment to selected needy. A
second approach that began to emerge in the last nineteenth century was that of
“universalism”. It stresses that all people in society should be entitle to certain
benefits-up to a minimum level and across a restricted range of services. This approach was
eventually used to arguing for the introduction of a pension for the aged poor.

Part III. Read the following passage and choose the correct answer (10 points)
Large animals that inhabit the desert have evolved a number of adaptations for reducing the effects of extreme heat. One
adaptation is to be light in color, and to reflect rather than absorb the Sun's rays. Desert mammals also depart from the normal
mammalian practice of maintaining a constant body temperature. Instead of trying to keep down the body temperature deep inside

the body, which would involve the expenditure of water and energy, desert mammals allow their temperatures to rise to what would
normally be fever height, and temperatures as high as 46 degrees Celsius have been measured in Grant's gazelles. The overheated
body then cools down during the cold desert night, and indeed the temperature may fall unusually low by dawn, as low as 34 degrees
Celsius in the camel. This is an advantage since the heat of the first few hours of daylight is absorbed in warming up the body, and an
excessive build-up of heat does not begin until well into the day.
Another strategy of large desert animals is to tolerate the loss of body water to a point that would be fatal for non-adapted animals.
The camel can lose up to 30 percent of its body weight as water without harm to itself, whereas human beings die after losing only
12 to 13 percent of their body weight. An equally important adaptation is the ability to replenish this water loss at one drink. Desert
animals can drink prodigious volumes in a short time, and camels have been known to imbibe over 100 liters in a few minutes. A very
dehydrated person, on the other hand, cannot drink enough water to rehydrate at one session, because the human stomach is not
sufficiently big and because a too rapid dilution of the body fluids causes death from water intoxication.
The tolerance of water loss is of obvious advantage in the desert, as animals do not have to remain near a water hole but can obtain
food from grazing sparse and far-flung pastures. Desert-adapted mammals have the further ability to feed normally when extremely
dehydrated, it is a common experience in people that appetite is lost even under conditions of moderate thirst.
1. What is the main topic of the passage?
A. Weather variations in the desert
C. Diseased of desert animals

B. Adaptations of desert animals
D. Human use of desert animals.

B. an animal that is not as well adapted as the camel

5. When is the internal temperature of a large desert mammal lower?

Part III. There are 10 mistakes in the passage. Find and correct them. (10 points)
There are numerous reason behind the choice of clothing we make, ranging from the practice to the bizarre, but in every
likelihood humans began wearing clothes in order to shield themselves of the elements.
‘The Iceman’, found mummifying in the ice of a glacier on the Italian-Austrian border in 1991, was still clad with remarkably
well-preserved garments which would obviously have protected him from the rain and cold five thousand years ago.
The clothing worn by people living in warmer climates further illustrates this basic function of clothing. In hot, dry desert
regions, people tend to wear cool, flowing materials which cover much of body, including the head. This helps keep them cool during
the heat of the day and helps to keep the wearer warm at night when temperatures increase dramatically. On the other hand, many
peoples living in tropical regions, with their constant high temperatures and humidity, are sparse clothed.

Not all clothing is functional, moreover, and at different times throughout history people, especially women, have worn
clothes which are impractical – restricting the wearer’s movements and in some cases cause physical discomfort. Examples of such
restrictive clothing can be seen in the hooped and corseted gowns worn by wealthy women in the 18th century, and in the opulent,
heavy robes traditionally worn by royalties. Such customs send a clear message that the wearer does not need to work but occupies
a position in society that others can be commanded to work for them.

D. READING COMPREHENSION
Part I. Read the text below and think of the word which best fits each space. Use only ONE word in each space.

“Nobody plans to fail, they simply fail to plan.” Nowhere is this truer (1)________ in the arena of public speaking. The classic
format for any talk (2)________ a beginning, a middle and an end. Think about how long you want the talk to (3)________ and plan
the content of the talk to fit the right amount of time. Also, think about your audience: make sure your approach to the subject of


your talk is (4)________ too complex nor too simple for them. If you are going to use prompts, small cards are quite good (5)________
they can be discreet and relatively unnoticeable compared (6)________ large sheets of paper.
Wherever possible, make sure you know the venue of your talk and (7)________ that people can see you and any slides or
diagrams you might be using to support your points. When (8)________ to a large group, try to keep very (9)________ to the front

secrecy, telling you things as a stage whisper in order to build this intimacy.
Part II. Choose the best word A, B, C or D to fill in spaces in the following passage.
You've (1)________ heard someone say that the reason you caught a cold was that you were 'run down'. People generally accept that
if you are (2)_______ pressure or run down you are more likely to get ill. But is this really true (3)_______ is it just an old wives' tale?
The problem with old sayings like this is that it's often difficult to (4)_______ whether they are true or not. For example, if you ask
people with colds whether they are feeling run down, they are (5)_______ certain to say yes. People without colds are more likely to
say no. So, how do you (6)_______ if it's the cold that is making them (7)_______ run down or the fact that they are run down that is
making them more likely to catch a cold? Now it seems there is a scientific answer to this question. And answer is yes - if you are run
down or under stress, you are more likely to catch a cold. Scientists at the Common Cold Research Centre ran a series of tests. They
got volunteers without colds to attend the centre, where they were first given a questionnaire to complete. The questions measured
the (8)_______ of stress each volunteer was under. The volunteers were then deliberately infected with a cold virus and left to see
whether they developed a cold. After many people had been tested, the researchers looked for a (9)_______ between the measured
stress level and the chances of catching a cold. They found that the higher the stress, the more likely the person was to catch a cold.
At the moment it is not known why stress makes someone more likely to become ill, but now (10)_______ the link has been found,
researchers might be able to investigate further. They may even find different ways of combating disease.

Part III. Read the following passage and choose the correct answer (20 points)
We are descendants of the ice age. Periods of glaciation have spanned the whole of human existence for the past 2
million years. The rapid melting of the continental glaciers at the end of the last ice age spurred one of the most dramatic climate
changes in the history of the planet. During this interglacial time, people were caught up in a cataclysm of human accomplishment,
including the development of agriculture and animal husbandry. Over the past few thousand years, the Earth’s climate has been
extraordinarily beneficial,and humans have prospered exceedingly well under a benign atmosphere.
Ice ages have dramatically affected life on Earth almost from the very beginning. It is even possible that life itself
significantly changed the climate. All living organisms pull carbon dioxide out of the atmosphere and eventually store it in sedimentary
rocks within the Earth’s crust. If too much carbon dioxide is lost, too much heat escapes out into the atmosphere. This can cause the
Earth too cool enough for glacial ice to spread across the land. In general the reduction of the level of carbon dioxide in the atmosphere
has been equalized by the input of carbon dioxide from such events as volcanic eruptions. Man, however, is upsetting the equation
by burning fossil fuels and destroying tropical rain forests, both of which release stored carbon dioxide. Thisenergizes the greenhouse
effect and causes the Earth to warm. If the warming is significant enough,the polar ice caps eventually melt.
The polar ice caps drive the atmospheric and oceanic circulation systems. Should the ice caps melt, warm tropical waters could circle
the globe and make this a very warm, inhospitableplanet.


Over the past century, the global sea level has apparently risen upwards of 6 inches, mainly because of the melting of glacial ice. If
present warming trends continue, the seas could rise as much as 6 feet by the next century. This could flood coastal cities and fertile
river deltas, where half the human population lives. Delicate wetlands, where many marine species breed, also would be reclaimed
by the sea. In addition, more frequent and severe storms would batter coastal areas, adding to the disaster of the higher seas.
The continued melting of the great ice sheets in polar regions could cause massive amounts of ice to crash into the ocean. This would
further raise the sea level and release more ice, which could more than double the area of sea ice and increase correspondingly the
amount of sunlight reflected back into space. The cycle would then be complete as this could cause global temperatures to drop
enough to initiate another ice age.
