Passage 2
Questions 6 to 10 are based on the following passage:
When aluminum was first produced about a hundred and fifty years ago, it was
so difficult to separate form the ores in which it was found that its price was
higher than that of gold. The price remained high until a new process was
discovered for refining the metal with the aid of electricity approximately
three quarters of a century later. The new method was so much cheaper that
aluminum because practical for many purposes, one of which was making pots and
pans.
Aluminum is lightweight, rustproof and easily shaped into different forms. By
mixing it with other metals, scientists have been able to produce a variety of
alloys, some of which have the strength of steel but weigh only one third as
much.
Today, the uses of aluminum are innumerable. Perhaps its most important use
is in transportation. Aluminum is found in the engine of automobiles, in the
hulls of boats. It is also used in many parts of airplanes. In fact, the huge
“airbus” planes would probably never have been produced if aluminum did not
exist. By making vehicles lighter in weight aluminum has greatly reduced the
amount of fuel needed to move them, Aluminum is also being used extensively in
the building industry in some countries.
Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite
(鋁土礦), which is one of its chief sources, is also one of the earth’s most
plentiful substances. As the source of aluminum is almost inexhaustible, we can
expect that more and more uses will be found for this versatile metal.
6. The price of aluminum was sharply reduced when people discovered a new
refining process with the aid of .
A. wind B. solar energy C. hydraulic power D. electricity
7. Aluminum is .
A. lightweight, rustproof but not easily shaped into different forms
B. heavyweight, rustproof and easily shaped into different forms
C. lightweight, rustproof and easily shaped into different forms
D. lightweight and easily shaped into different forms but it is easy to
become rusty
8. Which of the following is NOT true?
A. Aluminum is widely used in transportation.
B. Aluminum is also used in many parts of airplanes.
C. Aluminum is being used extensively in the building industry.
D. Aluminum is not used in its pure form.
9. Aluminum is found on earth mostly in the form of .
A. pure metal B. bauxite C. gold D. liquid
10. What is the passage talking about?
A. The features of aluminum and its functions. B. The process of
aluminum.
C. The discovery of aluminum. D. The promising future of aluminum.
What does the future hold for the problem of housing? A good deal depends, of
course, on the meaning of “future”. If one is thinking in terms of science
fiction and the space age, it is at least possible to assume that man will have
solved such trivial and earthly problems as housing. Writers of science fiction,
from H.G. Wells onwards, have had little to say on the subject. They have
conveyed the suggestion that men will live in great comfort, with every
conceivable apparatus to make life smooth, healthy and easy, if not happy. But
they have not said what his house will be made of. Perhaps some new building
material, as yet unimagined, will have been discovered or invented at least. One
may be certain that bricks and mortar(泥灰，灰漿) will long have gone out of
fashion.
But the problems of the next generation or two can more readily be imagined.
Scientists have already pointed out that unless something is done either to
restrict the world’s rapid growth in population or to discover and develop new
sources of food (or both), millions of people will be dying of starvation or at
the best suffering from underfeeding before this century is out. But nobody has
yet worked out any plan for housing these growing populations. Admittedly the
worst situations will occur in the hottest parts of the world, where housing can
be light structure or in backward areas where standards are traditionally low.
But even the minimum shelter requires materials of some kind and in the teeming,
bulging towns the low-standard “housing” of flattened petrol cans and dirty
canvas is far more wasteful of ground space than can be tolerated.
Since the war, Hong Kong has suffered the kind of crisis which is likely to
arise in many other places during the next generation. Literally millions of
refugees arrived to swell the already growing population and emergency steps had
to be taken rapidly to prevent squalor(骯臟)and disease and the spread crime. The
city is tackling the situation energetically and enormous blocks of
tenements(貧民住宅)are rising at an astonishing aped. But Hong Kong is only one
small part of what will certainly become a vast problem and not merely a housing
problem, because when population grows at this rate there are accompanying
problems of education, transport, hospital services, drainage, water supply and
so on. Not every area may give the same resources as Hong Kong to draw upon and
the search for quicker and cheaper methods of construction must never cease.
1.What is the author’s opinion of housing problems in the first
paragraph?
A.They may be completely solved at sometime in the future.
B.They are unimportant and easily dealt with.
C.They will not be solved until a new building material has been
discovered.
D.They have been dealt with in specific detail in books describing the
future.
2.The writer is sure that in the distant future ___.
A.bricks and mortar will be replaced by some other building material.
B.a new building material will have been invented.
C.bricks and mortar will not be used by people who want their house to be
fashionable.
D.a new way of using bricks and mortar will have been discovered.
3.The writer believes that the biggest problem likely to confront the world
before the end of the century ___.
A.is difficult to foresee.
B.will be how to feed the ever growing population.
C.will be how to provide enough houses in the hottest parts of the world.
D.is the question of finding enough ground space.
4.When the writer says that the worst situations will occur in the hottest
parts of the world or in backward areas, he is referring to the fact that in
these parts ___.
A.standards of building are low.
B.only minimum shelter will be possible.
C.there is not enough ground space.
D.the population growth will be the greatest.
5.Which of the following sentences best summarizes Paragraph 3?
A.Hong Kong has faced a serious crisis caused by millions of refugees.
B.Hong Kong has successfully dealt with the emergency caused by millions of
refugees.
C.Hong Kong’s crisis was not only a matter of housing but included a number
of other problems of population growth.
D.Many parts of the world may have to face the kind of problems encountered
by Hong Kong and may find it much harder to deal with them.

Passage 2
Questions 6 to 10 are based on the following passage:
There are two kinds of memory: shot-term and long-term. Information in
long-term memory can be remembered at a later time when it is needed. The
information may be kept for days or weeks. However, information over and over.
The following experiment shows how short-term memory has been studied.
Henning studied how students who are learning English as a second language
remember vocabulary. The subjects in his experiment were 75 college students.
They represented all levels of ability in English: beginning, intermediate, and
native-speaking students.
To begin, the subjects listened to a recording of a native speaker reading a
paragraph in English. Following the recording, the subjects took a 15-question
test to see which words they remembered, each question had four choices. The
subjects had to circle the word they had heard in the recording. Some of the
questions had four choices that sound alike. For example, weather, whether,
wither, and wetter are four words that sound alike. Some of the questions had
four choices that have the same meaning. Method, way, manner, and system would
be four words with the same meaning. Finally the subjects took a language
proficiency test.
Henning found that students with a lower proficiency in English made more of
their mistakes on words that sound alike; students with a higher proficiency
made more of their mistakes on words that have the same meaning. Henning’s
results suggest that beginning students hold the sound of words in their
short-term memory, and advanced students hold the meaning of words in their
short-term memory.
6. Henning made the experiment in order to study .
A. how students remember English vocabulary by short-term memory
B. how students learn English vocabulary
C. how to develop students’ ability in English
D. how long information in short-term memory is kept
7. Which of the following statements is TRUE according to the passage?
A. Information in short-term memory is different from that in long-term
memory.
B. Long-term memory can be achieved only by training.
C. It is easier to test short-term memory than long-term memory.
D. Henning gave a separate test on vocabulary to his students.
8. From Henning’s result we can see that .
A. beginners have difficulty distinguishing the pronunciation of words
B. advanced students remember words by their meaning
C. it is difficult to remember words that sound alike
D. it is difficult to remember words that have the same meaning
9. The word “subjects” in the passage means .
A. memory B. the theme of listening material
C. a branch of knowledge studied D. the students experimented on
