Passage Four "Cool" is a word with many meanings. Its old meaning is used to express

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

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.

听力原文： Did you know that vegetables can be tricked into growing in climates they are not accustomed to？ Cool climate vegetables are now able to be grown in places as hot as Hawaii. In Hawaii, marine engineers have been able to actually convince such vegetables that they're living in cooler climate. That way they grow faster and taste better. What these engineers have been using is very simply cold sea water. How do they use it？ They place pipes hi the mil and the cold water flow in through them cools the air. This stimulates plants growth mid enables gardeners in tropical climates to glow crops from cooler climates. Also some of these pipes m exposed to the air and they con dense moisture and thus litigate the garden. What's especially appealing about this process is that nothing damaging to the natural environment is being used. Another innovative use for cold ocean water is to cool buildings. Engineers believe that, for example, the entire west coast of the United Stales could be air-conditioned using sea water.

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

Directions: There are four passages in this part. Each passage is followed by some questio

ns or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.

Passage 1 Questions I to 5 are based on the following passage:

Thousands of years ago, in the middle of an ocean, miles from the nearest island, an undersea volcano broke out. The hot liquid piled higher and higher and spread wider and wider. In this way, an island rose up in the sea.

As time went on, hot san and cool rains made the rock split and break to pieces, Sea waves dashed against the rock. In this way, soil and sand came into being.to grow taller.

Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch. Insects couldn't stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.

1. The passage centers on _______.

A how an undersea volcano broke out

B how an island rose up in the sea

C how soil was formed on a new island

D how life began on a volcano- produced island

Passage Three Many theories about the origin of the ocean have been proposed by scientis

Passage Three

Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form. a crust of rock that was many miles thick.

Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.

In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.

The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.

41. This passage mainly talks about ______.

A. the origin of the earth

B. the origin of the ocean

C. the history of the earth

D. the forming of the earth's crust

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

Running a fever was once thought to be the prerogative of warm-blooded creatures, whose internal temperatures are independent of the weather. But, as Matthew Kluger reported in "The Importance of Being Feverish" (January 1976), lizards can also develop fevers, even though there is no question that they are cold-blooded. They raise their temperatures by moving into the sun or, in the case of Kluger's experiments, under a sun lamp. And it seems to do them some good. Sick lizards kept in cages at feverish temperatures fare much better than their counterparts in normal and cool environments.

Now, fever has spread to invertebrates(无脊椎动物). Recent studies have shown that crayfish and scorpions can develop fevers. Crayfish injected with bacteria and scorpions injected with prostaglandins(前列腺素) swam and scuttled to hot areas.(Prostaglandins are hormones thought to be instrumental in the development of a fever.)

Evidence is also mounting that moderate fevers have their benefits, which might explain why the fever process is so widespread. Leukocytes, white blood cells that are active in fighting bacterial infections, are more mobile at febrile temperatures. And fevers reduce the amount of iron available to bacteria. That reduction, combined with high temperatures, has been shown to inhibit bacterial growth.

Which of the following best states the main idea of the passage？

A．Cold-blooded animals can develop fevers.

B．There are benefits to developing fevers.

C．Fevers inhibit bacterial growth.

D．Lizards can develop fevers.

Task 1

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.

Walking is the easiest and simplest form. of exercise. By putting one foot in front of the other, you can start to walk your ways towards a healthier lifestyle. Walking is an easy way to challenge the cardiovascular system (心血管系统), while at the same time building muscles. But to achieve these goals, a little more than a gentle walk around the block is required.

Walking actually burns as many calories (卡洛里) as running the same distance —— if done in the correct manner and at a reasonable pace (步伐).

Start with a basic program that you can complete three or four times a week. This should include five main steps:

——A beginning warm-up for about 5 minutes.

——A little bit faster period of 5 minutes at medium level (中等速度)

——A 10-minute “burning” at a high level.

——A 5-minute cool down period at a low level again.

——A suitable walking pace of around 5 kilometers per hour will burn around 80 calories in 30 minutes.

According to the passage, walking is a simple way to______.

A．lose weight

B．avoid heart attacks

C．cure blood diseases

D．strengthen heart functions
