Unless we spend money to spot and prevent asteroids（小行星) now, one might crash into Eart

Unless we spend money to spot and prevent asteroids(小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.

Asteroids are bigger versions of the meteoroids(流星) that reace across the night sky. Most orbit the sun far from Earth and don't threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth.

Buy $ 50 million worth of now telescopes right now. Then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we'll have a way to change its course.

Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn't be cheap.

Is it worth it？ Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare— but if one did fall, it would be the end of the world. "If we don't take care of these big asteroids, they'll take care of us," says one scientist. "It' s that simple."

The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth？ "The world has less to fear from doomsday(毁灭性) rocks than from a great nuclear fleet set against them," said a New York Times article.

What does the passage say about asteroids and meteoroids？

A．They are heavenly bodies different in composition.

B．They are heavenly bodies similar in nature.

C．There are more asteroids than meteoroids.

D．Asteroids are more mysterious than meteoroids.

A scientist who wants to predict the way in which consumers （消费者) will spend their mone

A scientist who wants to predict the way in which consumers (消费者) will spend their money must study consumer behavior. He must obtain data both on the resources of consumers and on the motives that tend to encourage or discourage money spending.

If an economist were asked which of three groups borrow most — people with rising incomes, stable incomes, or decreasing incomes—he would probably answer, those with decreasing incomes. Actually in the years 1947 ~ 1950, the answer was: people with rising incomes. People with decreasing incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions (假设) about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true.

The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months, "she said, "we' 11 have pay more for meat and milk; we' 11 have less to spend on other things. "Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be disliked and buyer's resistance may be produced. This is shown by the following typical comment; "I just don't pay these prices; they are too high. " The investigations mentioned above were carried out in America; The condition most helpful to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology (心理学) .

According to the passage, if one wants to predict the way spend their money, he should

A．rely on traditional assumptions about earning and spending

B．try to encourage or discourage consumers to spend money

C．carry out investigations on consumer behavior. and get data on consumers incomes and money spending motives

D．do researches in consumer psychology in a laboratory

第8题

Most of us think that, work is the central, dominating fact of life. We spend more than ha

lf our conscious hours on work, preparing for work, commuting to and from work. What we do there largely determines our standard of living and to a great extent the status we are accorded by our fellow citizens as well. It is sometimes said that because leisure has become more important, the indignities and injustices of work can be pushed into a corner, that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. I desparately reject that. For the foreseeable future the material and psychological rewards which work can provide, and the conditions in which work is done, will continue to play an essential part in determining the satisfaction that life can offer. Yet only a small minority can control the pace at which they work or the conditions in which their work is done; only for a small minority does work offer scope for creativity, imagination, or initiative.

Inequality at work is still one of the cruellest and most glaring forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial life, many of which arise directly or indirectly from the frustrations created by inequality at work, unless we tackle it head-on. Still less can we hope to create a decent and human society.

The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning; they can exercise responsibility; they have a considerable degree of control over their own-and others'-- working lives. The most important thing is that they have opportunity to initiate. By contrast, for most manual workers, and for a growing number of white-collar workers, work is a boring, dull, even painful experience. They spend all their working lives in conditions which would be regarded as intolerable--for themselves--by those who make the decisions which let such conditions continue. The majority have little control over their work; it provides them with no opportunity for personal development. Often production is so designed that workers are simply part of the technology. In offices, many jobs are so routine that workers justifiably feel themselves to be mere cogs in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated from their work and their firm, whether it is in public or in private ownership.

In the writer's opinion, people judge others by ______.

A．the type of work they do

B．the place where they work

C．the time they spend at work

D．the amount of money they earn
