　　No one knows why we sleep, but it's certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days----they think less clearly, and they fall asleep during the working hours; some may have hallucinations(幻觉).

　　There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and half hours each night and probably more than 60 percent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four percent or so find that they want ten hours or more. If you feel all right, you're probably getting enough sleep. The important thing is not to worry how much other people get----their needs may be different. Exercise doesn't seem to increase the need for sleep----office workers, for example, sleep for about as long as people doing physically active work.

　　Children sleep more than grown-ups----perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teen-age. Sleep patterns also tend to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.

[　　]

A．they have hallucinations

B．they feel sleepy during the working hours

C．they don't have enough sleep

A．All grown-ups must have at least eight-hour sleep

B．Most of grown-ups sleep for seven or eight hours

C．Quite a few people need only 5 hours or less for them to sleep

D．No grown-ups sleep more than ten hours

3．Whether you have got enough sleep is judged by ________.

[　　]

A．how many hours you have slept

B．how many hours you need to sleep

C．whether you do exercise and physical work

D．whether you feel fresh and energetic

　　We have just climbed out of a spaceship onto the surface of the moon. Behind us is the ship, half in the sunlight and half in the deep shadow. A few miles ahead is a wall of mountains against the black sky. And there, as though resting on the mountains, is a great ball of light, beautifully coloured in blue and brown with a patch of dazzling white at the top. It is our own far-away world----the earth.

　　We take step and rise like prize jumpers-up, float and down again. Hopping (or jumping ) carefully, we explore the valleys, the sloping crater(火山口) walls, the shadowy crater floors.

As civilization develops in the direction of technology, it's no longer so difficult to supply the human beings with enough food, houses, clothes and warmth. Then we'll be faced with a choice between using technology to meet more needs which have by far been regarded as unnecessary or, on the other hand, using technology to reduce the number of hours of work which a man must do in order to earn a certain standard(标准) of living above what is necessary for comfort and happiness or we leave it at this level and work shorter hours. It seems to be sure that, by that time, mankind will choose to work shorter and shorter hours in their paid jobs. It follows that the housewives will also expect to be able to have more spare time in their life without lowering the standard of living. It also follows that there will be no human servants working for others doing the housework. It is not supposed that housewives will do all the housework themselves----robots will do it instead!

[　　]

A．Technology is important in the development of civilization.

B．To live unnecessary better or to work shorter hours?

2．Which of the following does the writer agree with?

[　　]

A．The higher the standard of living is, the better.

B．The present standard of living is high enough for mankind.

C．Instead of hoping for too high a standard of living, mankind should use technology to help themselves work shorter and shorter hours.

D．Housewives should take servants' place to do the housework

3．As is mentioned in the passage, ________.

[　　]

A．food, houses, clothes and warmth are no longer problems to mankind now

B．mankind will be faced with a choice as civilization develops in the direction of technology

C．a man will be paid less if he works shorter hours.

D．a man will be paid more to work shorter hours.

B．There will be no human servants; non-human servants will take their place.

C．Housewives will have more spare time; they will be free from much housework.

D．Robots will come into our daily life; they will help us enjoy more spare time.

5．Which of the following is the right order of the development of civilization?

[　　]

a．Man begins to work shorter hours.

　　Most people agree that there will be changes in the future. However, many people don't agree on what the changes will be, especially when we look further and further ahead.

　　Changes that may come soon the easier to be predicated (预报). That is because they may have already started. Also, there has not been enough time for great unknowns to start up and affect the changes.

　　One change that most people agree on is that the world will have more people. In part this is because of better health care. Older people will live longer, and fewer babies will die.

　　Another change that many people agree on is that oil and its products will cost more. Oil is a natural resource (资源). We are beginning to use it up. As we use up more oil, there will be less left in the world. That will make the remaining oil worth more money. So the remaining oil will cost its users more.

　　America has built a spaceship. This spaceship will soon travel almost weekly between the earth and space just above Earth's atmosphere. America's spaceship will change the way we view space travel. In the past, only a few highly-trained people went into space. Soon the spaceship will take many kinds of people and things. Room on the spaceship has even been bought for the science students in the Clear Creek School District near Houston, Texas. College students are going too. Businesses are also planning to send workers and machines into space.

　　Out on the road the jeep was already waiting. As I got on beside him, he sat up the town and heading with great speed in the direction of Bacalar. My hat blew away but when I asked him to stop, he refused. We were being followed by spies and it was necessary to drive fast to throw them off.

　　The floors of the ocean contain many riches that can be used by man. Oil and chemicals and minerals are already taken from the sea. By using nuclear (核) energy, ocean water can be turned into fresh water by removing the salt. In the near future, it is possible for human beings to produce food from farms under the sea. Food grown in the sea could help meet the needs of the fast-increasing population all over the world, thousands of which go hungry every day. About 10----15% of the world population don't have enough food. Some scientists believe that someday the sea will be used to make electric power. This would help meet the need for more power for the world's industries. The decreasing supply of coal, oil and gasoline shows the need to find new kinds of power is urgent.

　　Millions of years ago, whales lived on land and walked on four legs. Today whales still have small bones, which can only be seen on the inside of them. No one knows why whales left the land to live in the water. However, scientists can imagine when the whales changed their living conditions, their bodies underwent a change----showing a more fish----like appearance. This new form offered less resistance to the water. And the whales could swim faster.　　Whales are not fish. A whale will die, just as a man will, if it stays under water too long. When a whale is under water it closes its nose and holds is breath. The air in its lungs becomes very hot and its lungs are full of water vapour. A whale rises to the surface and breathes, its hot breath produces a fountain of water that rises high in the air. A man produces the same effect when he breathes warm air on a cold morning.
