1、【题目】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,灰浆) 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(肮脏)and disease and the spread crime. The city is tackling the situation energetically and enormous blocks of tenements(贫民住宅)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.

1、【题目】Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They drift about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year. The sea’s plankton generates more than twice as much.

Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now marine scientists have at last begun to study this possibility, especially as the sea’s resources loom even more important as a means of feeding an expanding world population.

No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.

One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill. Growing to two or three inches long, krill provide the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Realizing that this whale may grow 100 feet and weigh 150 tons at maturity, it is not surprising that each one devours more than one ton of krill daily.

Krill swim about just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic. Because of their pink color, they often appear as a solid reddish mass when viewed from a ship or from the air. Krill are very high in food value. A pound of these crustaceans contains about 460 calories—about the same as shrimp or lobster, to which they are related.

If the krill can feed such huge creatures as whales, many scientists reason, they must certainly be contenders as new food source for humans.

1.Which of the following best portrays the organization of the passage?

A.The author presents the advantages and disadvantages of plankton as a food source.

B.The author quotes public opinion to support the argument for farming plankton.

C.The author classifies the different food sources according to amount of carbohydrate.

D.The author makes a general statement about plankton as a food source and then moves to a specific example.

2.According to the passage, why is plankton regarded to be more valuable than land grasses?

A.It is easier to cultivate.

B.It produces more carbohydrates.

C.It does not require soil.

D.It is more palatable.

3.Why does the author mention “planktonburgers”?

A.To describe the appearance of one type of plankton.

B.To illustrate how much plankton a whale consumes.

C.To suggest plankton as a possible food sources.

D.To compare the food values of beef and plankton.

4.What is mentioned as one conspicuous feature of krill?

A.They are the smallest marine animals.

B.They are pink in color.

C.They are similar in size to lobsters.

D.They have grass like bodies.

5.The author mentions all of the following as reasons why plankton could be considered a human food source except that it is ___.

A.high in food value.

B.in abundant supply in the oceans.

C.an appropriate food for other animals.

D.free of chemicals and pollutants.

1、【题目】Part I Reading Comprehension

Directions: In this part there are four passages. Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet.

Passage 1

Questions 1 to 5 are based on the following passage:

Ask three people to look the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it.

Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses—in this case our eyes—tell us.

Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.

1. Seeing and perceiving are .

A. the same action

B. two separate actions

C. two actions carried on entirely by eyes

D. several actions that take place at different times

2. Perceiving is an action that takes place .

A. in our eyes

B. only when we think very hard about something

C. only under the direction of a psychologist

D. in every person’s mind

3. People perceive different things about the same scene because .

A. they see different things B. some have better eyesight

C. they cannot agree about things D. none of these

4. Which of the following is implied but not stated in the passage?

A. Psychologists do not yet know people see.

B. The experiments in which all factors are controlled are better.

C. The study of perception is going on now.

D. Perception does not involve psychological factors.

5. The best title for this selection is .

A. How We See

B. Learning about Our Minds through Science
