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

D. both A and C

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 There are two factors which determine an individual's intelligence. The first

Passage Two

There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual the sort of environment in which he is reared (抚养). If an individual is handicapped environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster (收养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

36. This selection can be titled ______.

A. Measuring Your Intelligence

B. Intelligence and Environment

C. The Case of Peter and Mark

D. how the Brain Influences Intelligence

Passage Three

How can we get rid of garbage.9 Do we have enough energy sources to meet our future energy needs？

These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the time it can save the land to hold garbage.

For a long time, people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.

Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs.

44. What two problems can man solve by burning garbage？

A. The shortage of energy and air pollution.

B. The shortage of energy and the land to hold garbage.

C. Air pollution and the shortage of fossil fuel.

D. Air pollution and the shortage of land to hold garbage.

Question 24 to 27 are based on the following passage.

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.

The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years.

The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active. These mice are living longer than the scientists thought —about a year and a half, but they arenot healthy. The are sick more often than the other two groups.

第6题

A moment's drilling by the dentist may make us nervous and upset. Many of us cannot stand

pain.

To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.

Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.

But there is a way to handle pain. Look at the Indian fakir(行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain; This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain.

The big thing in withstanding pain is our attitude toward it. If the dentist says, "This will hurt a little, it helps us to accept the pain. By staying relaxed,' and by treating the pain as an interesting sensation, we' can handle the pain without falling apart. After all; although pain is an unpleasant sensation, it is still a sensation, and sensations are the stuff of life.

26. The passage is mainly about______.

A) how to stiffer pain

B) how to avoid pain

C) how to handle pain

D) how to stop pain

Soldiers and other military people wear uniforms with various other symbols to indicate

their status.But in the business world everyone wears more or less similar suits，and you cannot tell at a glance who ranks higher or lower than another.So how do people in the business world show their superiority？ An attempt to study this was made by two researchers using a series of silent films.They had two actors play the parts of an executive(经理)and a visitor，and switch roles each time.The scene had one man at his desk playing the part of an executive，while the other，playing the part of a visitor，knocks at the door，opens it and approaches the desk to discuss some business matter.

The audience watching the films was asked to rate the executive and the visitor in terms of status.A certain set of rules about status began to emerge from the ratings.The visitor showed the least amount of status when he stopped just inside the door to talk across the room to the seated man.He was considered to have more status when he walked halfway up to the desk，and he had the most status when he walked directly up to the desk and stood right in front Of the seated executive.

Another thing that affected the status of the visitor in the eyes of the observers was the time between knocking and entering.For the seated executive，his status was also affected by the time between hearing the knock and answering.The quicker the visitor entered the room，the more status he had.The longer the executive took to answer，the more status he had.

第10题

Most cities and/or states in the U. S. collect a sales tax on almost everything you buy. Y

ou must ask when you move into a new community how much the local sales tax is, and what items are and are not taxable. Both taxable items and the amount of tax vary considerably from place, from one of two percent in some places up to eight or ten in others. The New York City sales tax, for examples, is currently 8% , so if you buy a pair of $40 shoes you will actually have to pay $43.20. This makes paying and getting correct change much more difficult (not to mention making .everything more expensive). We say in America that only two things in life are unavoidable: one is death and the other taxes.

Another thing that makes money exchanges more complicated is tipping. The Chinese people have happily put an end to tipping, but Westerners are still plagued with this indignity. Waiters and waitresses, cab drivers, hotel bellboys, barbers and hairdressers and all sorts of other people must be tipped. Their employers give them low wages because it is expected that you, the customer, will make up the difference. If you don' t, the service person can' t earn a living. Tipping also varies from place to place, generally in the area of 15% of your bill (before taxes), but again you should ask local residents whom to tip and how much.

There is another kind of tipping as well. You are generally expected to give something (either cash or a bottle of whisky) to the mailman and to your building "super" at Christmas time. You should discuss this also with neighbors and colleagues.

The main idea of this passage is ______.

A．shopping and tipping

B．sales and shopping

C．sales taxes and tipping

D．sales taxes and people
