Passage 2

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our tendency to give and receive support from one another under stressful circumstances. Social support consists of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to cope with major life changes and daily hassles(困难). People with strong social ties live longer and have better health than those without such ties. Studies over a range of illnesses, from depression to heart disease, reveal that the presence of social support helps people fend off (挡开)illness, and the absence of such support makes poor health more likely.

Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others despite our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting (转移…注意力)us from our worries and troubles. Finally, other people may give us instrumental support — financial aid, material resources, and needed services — that reduces stress by helping us resolve and cope with our problems.

 

 

A.C. depends on their ability to deal with daily worries and troubles

 

B.A. relies on the help they get form others

 

C.D. is closely related to their strength for coping with major changes in their lives

 

D.B. has much to do with the amount of support they get from others

 

E.it enables us to eliminate our faults and mistakes

 

F.C. it makes our leisure-time activities more enjoyable

 

G.A. it helps strengthen our ties with relatives

 

H.D. it draws our attention away from our worries and troubles

 

I.A. instrumental support

 

J.D. financial aid

Passage 4

Space is a dangerous place, not only because of meteors(流星)but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food, which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed(畸形的)children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys; the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

 

 

A.?C. Effects of Space Radiation

 

B.Importance Protection against Radiation

 

C.?B. Research on Radiation

 

D.?A. Astronauts in the Outer Space

 

E.A. is insignificant

 

F.B. seems overestimated

 

G.is enormous

 

H.D. remains unknown

 

I.B. the effect of exposure to radiation is slow in coming

 

J.radiation is avoidable in space exploration

 

BA.D. astronauts in spacesuits needn’t worry about radiation damage

 

BB.

A. exposure to even tiny amounts of radiation is fatal

 

BC.astronauts will have deformed children or grandchildren

 

BD.D. radiation is not a threat to well-protected space explorers

 

BE.B. protection from space radiation is no easy job

 

BF.the Apollo mission was very successful

 

BG.it supplies the heat necessary for human survival

 

BH.D. it screens off the falling meteors

 

BI.A. it protects him against the harmful rays from space

 

BJ.it provides sufficient light for plant growth

Passage 3

 

When cars first started appearing on the streets of the world, few people took them seriously. They were toys—play things for grown men who didn’t have much to do. No one thought that the automobile would ever become the world’s most popular form of transportation.

There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.

In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.

What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arctic (北极的)peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.

Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent (进步). The progress from a rattle (拨浪鼓)used by a baby in 3000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.

 

 

A.?A. in toy-making there is a continuity in the sue of materials

 

B.?D. even a simple toy can mirror the artistic tastes of the time

 

C.?B. even the simplest toys can reflect the progress of technology

 

D.it often takes a long time to introduce new technology into toy-making

 

E.D. most girls would like to follow their mothers’ professions

 

F.C. boys like to play with their fathers while girls with their mothers

 

G.B. most boys would like to follow their fathers’ professions

 

H.A. their social roles are rigidly determined

 

I.B. Toys have remained basically the same all through the centuries.

 

J.C. The toy industry has witnessed great leaps in technology in recent years.

 

BA.D. Toys are playing an increasingly important role in shaping a child’s character.

 

BB.A. The craftsmanship in toy-making has remained essentially unchanged.

 

BC.B. also appeal greatly to adults

 

BD.|D. reflect the pace of social progress

 

BE.C. are not characterized by technological progress

 

BF.A. follow a direct line of ascent

 

BG.the basic characteristics of toys are the same the world over

 

BH.A. technological advances have greatly improved the durability of toys

 

BI.B. the improvement of craftsmanship in making toys depends on the efforts of

universities

 

BJ.C. the exploration of the universe had led to the creation of new kinds of toys

 

56.[单选题] Passage 1

The United States covers a large part of the North American continent. Its neighbors are Canada to the north and Mexico to the south. Although the United States is a big country, it is not the largest in the world. In 2000, its population was over 222 million.

When this land first became a nation, after winning its independence from England, it had thirteen states. Each of the states was represented on the American flag by a star. All these states were in the eastern part of the continent. As the nation grew toward the west, new states were added and new stars appeared on the flag. For a long time, there were 48 stars. In 1959, however, two more stars were added to the flag, representing the new states of Alaska and Hawaii.

Indians were the first people of the land which is now the United States. There are still many thousands of Indians now living in all parts of the country. Sometimes it is said that the Indians are “the only real Americans”. Most Americans come from all over the world. Those who came first in greatest numbers to make their homes on the eastern coast of North America were mostly from England. It is for that reason that the language of the United States is English and that its culture and customs are more like those of England than those of any other country in the world.

B.America is the largest country in the world.
