Passage Four

You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.

There are four basic types of blood; A, B, AB and O. A simple test can indicate a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.

Because of substances contained in each type, the four groups must be transfused carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group, hence it is often called the universal donor. For the opposite reason, AB sometimes called the universal recipient. However, because so many reactions can occur in transfusions, patients usually receive only' salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to avoid any bad reactions to the transfusion.

There is a relationship between your blood type and your nationality. Among Europeans and people of European ancestry, about 42 percent have type A while 45 percent have type O. The rarest is type AB. Other races have different percentages. For example, some American Indian groups have nearly 100 percent type O.

48. A good title for this passage is______.

A. Getting Blood and Plasma

B. Special Blood and Colors

C. Human Blood Types

D. The Blood Bank of a Hospital

Passage Four After a busy day of work and play, the body needs to rest. Sleep is necessary

Passage Four

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!

46. A good title for this passage is ______.

A. Sleep

B. Good Health

C. Dreams

D. Work and Rest

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.

C. Two miles.

D. Less than four miles.

Passage Four If you are like most people, your intelligence varies from season to season

Passage Four

If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of year. A noted scientist, Ells- worth Huntington (1876-1947) concluded from other men's work and his own among peoples in different climates that climate and: temperature have a definite effect on our mental abilities.

He found that cool weather is much more favorable for creative thinking than summer heat is. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that mental, abilities of large numbers of people tend to be lowest in the summer.

Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature.

Fall is the next best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!

46. According to the passage, your mental ability ______.

A. depends on your attitude towards people in different time of the year

B. changes for the worst when you dislike most people in hot season

C. will be best in winter and worst in summer if you want to be creative

D. turns to be more powerful in spring than in any of the other seasons

Passage Four

"Cool" is a word with many meanings. Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings.

"Cool" can be used to express feelings of interest in almost anything. When you see a famous car in the street, maybe you will say, "It's cool. ' You may think, "He's so cool," when you see your favorite football player.

We all maximize (扩大) the meaning of "cool". You can use it instead of many words such as "new" or "surprising". Here's an interesting story we can use to show the way the word is used. A teacher asked her students to write about the waterfall (瀑布) they had visited. On one student's paper was just the one sentence, "It's so cool." Maybe he thought it was the best way to show what he saw and felt.

But the story also shows a scarcity of words. Without "cool", some people have no words to show the same meaning. So it is quite important to keep some credibility (可信性). Can you think of many other words that make your life as colorful as the word "cool"？ I can. And I think they are also very cool.

46. We know that the word "cool" has had______.

A. only one meaning

B. no meanings

C. the same meaning

D. many different meanings

第7题

Because we can feel that things are heavy, we think of weight as being a fixed quality in

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

Ⅳ. Reading Comprehension (75 points)

Directions: There are five reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blacken the corresponding letter on the answer sheet.

Passage One

Are you a good reader？ Good readers know that reading isn't just about knowing words— it's a way of thinking. Here are some tips that may be of some help.

Think before you read. Before you read the text, ask yourself the questions that why you are reading it and what you want to get from it. These will help you choose what words you need to know and what words you can skip or scan.

Think while you are reading. Can you get the meaning of the text without looking up new words in a dictionary？ A text will often give examples that may help you understand some words. For example: Many large Russian cities, such as Chelyabinsk and Irkutsk, have taken steps to protect their culture. The words "Chelyabinsk' and "Irkutsk' may be new to us, but the sentences before and after it tell us what they are.

Think after you read. What is the main idea of the text？ Is the text too easy or too hard for you？

If you practice reading and thinking in this way, you will become a better reader and you will learn better and faster.

31. This passage is probably taken from______.

A. a newspaper for general readers

B. a magazine for language teachers

C. a book for language learners

D. an advertisement for a new book

Passage Four Archimedes was a famous Greek mathematician and scientist. He was born arou

Passage Four

Archimedes was a famous Greek mathematician and scientist. He was born around 287 BC and he died in the year 212 BC.

Archimedes is most well-known for one specific idea that he came up with. "Archimedes's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.

It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.

48. A good title for the selection is______.

A. Archimedes

B. Archimedes's Principle

C. A Gold and Silver Crown

D. The King of Syracuse
