Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health.

In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years.

Passage Two

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.

People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out

of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.

40. We should take good care of our eyes ______.

A. only when we cannot see perfectly

B. only when we can see well

C. even if we can see well

D. only when we realize how important our eyes are

Passage Two

How can a single postage stamp be worth $ 16,800？

Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one in expensive' postage stamp has made the stamp worth a million and a half times its original value.

The mistake was made more than a hundred years ago in the British colony of Mauritius, a small is land in the Indian Ocean. In 1847 an order for stamps was sent to a London printer, and Mauritius was to become the fourth country in the world to issue stamps.

Before the order was filled and delivered, a ball (舞会) was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the de sign for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the sever al hundred stamps that he printed.

Today there are only twenty-six of these misprinted stamps left--fourteen "One Penny Orange-Reds" and twelve "Two Penny Blues". Because of the Two Penny Blue's rareness (罕见) and age, collectors have paid as much as $ 16,800 for it.

36. A postage stamp's value to collectors is raised if ______.

A. there are few others like it

B. there are no errors on the stamps

C. a mistake is made in the ,printing

Passage Two

One day I was at the airport waiting for a ticket to New York and the girl in the ticket office said, "I'm sorry, I can't sell you a ticket. Our computer is down."

"If your computer is down, just write me out a ticket."

"I can't write you out a ticket. The computer is the only one allowed to do so."

I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do？'

"We give the computer the information about your trip, and then it tells us whether you can fly with us or not."

"So when it goes down, you go down with it."

"That's good, sir. '

"How long will the computer be down？" I wanted to know.

"I have no idea. There's no way we can find out without asking the computer."

After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes？ They're still flying, aren't they？"

"I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.

Passage Four

"We're more than halfway (中途) now; it's only two miles farther to the tavern (客栈) ," said the driver.

"I'm glad of that," answered the stranger, in a more sympathetic way. He meant to say more but the east wind blew clear down a man's throat if he tried to speak. The girl's voice was quite attractive; however, later he spoke again.

"You don't feel the cold so much at twenty below zero in the Western country. There isn't such damp chill (潮冷)", he said, and then it seemed as if he had blamed the uncomplaining young driver. She had not even said that it was a bad day, and he began to be conscious of a warm hopefulness of spirit, and sense of pleasant adventure under all the woolen scarves.

"You'll have a cold drive going back," he said anxiously, and put up his hand for the twentieth time to see if his coat collar was as close to the back of his neck as possible.

"I shall not have to go back!" cried the girl, with eager pleasantness. "I'm on my way home now. I drove over early just to meet you at the train. We had word that someone was coming to the tavern."

46. How far was the drive from the train to the tavern？

A. One mile.

B. About four miles.

Passage Two

Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.

In the early years, these schools were much alike. Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers (大臣) or teachers.

In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history.

As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.

Today, there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with (涉及) special fields of learning. There's so much to learn that one kind of school can't offer it all.

36. The oldest university in the US is______.

A. Yale

B. Princeton

C. Harvard

D. Columbia

Passage One

The law says that women should have the chance of doing the same jobs as men and earn the same as them．

The reality is very different．Women lose because, 25 years after the Equal Pay Act,many of them still get paid less than men．

They lose because they do lower-paid jobs which men just won't consider．And they lose because they are the ones who interrupt a career to have children．

All this is reported in an independent study ordered by the Government's Women's Unite．

The biggest problem isn't equal pay in workplaces such as factories．It is a sort of work women do．Make a list of the low-paid jobs, then consider who do them．

Try nurses, secretaries, cleaners, clerks, teachers in primary schools, dinner ladies,and child care helpers． Not a lot of men among that group, are there？

Yet some of those jobs are really important．Surely no one would deny that about nurses and teachers, for a start．

So why do we reward the people who do them so poorly？ There can be only one answer—because they are women．

This is not going to be put right overnight． But the Government which employs a lot of them, and other bosses have to make a start．

It is disgraceful(可耻的) that we have gone into the 21st century but still treat women as second-class citizens．

Women should have the chance of doing the same jobs and be paid equally as Men()．

A． after 25 years

B． according to the law

C． as a result of the Equal Pay Act

D． because women are as strong as men

Passage Two

What is your favorite color？ Do you like yellow, orange or red？ If you do, you must be an optimist (乐观者), a leader, an active person. Do you prefer grays and blues？ Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. At least this is what psychologists (心理学家) tell us. They have been seriously studying the meaning of color preference (爱好), and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

A yellow room makes us feel more cheerful and more comfortable than a dark green one. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.

Remember that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.

36. According to this passage,______.

A. one can choose his color preference

B. one is born with his color preference

C. one's color preference is changeable

D. one has to choose his favorite color as soon as he can see clearly

an object, but it is not really fixed at all. If you could take a one pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound.

Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space？ The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.

If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.

The best title for this passage is______.

A．The Earth Weight

B．Weight in Space

C．Changing Weight on the Earth

D．Weight on and off the Earth
