Life in the Universe
Many scientists today are convinced that life exists elsewhere in the universe - life probably much like that on our own planet. They reason in the folio, wing way.
As far as astronomers (天文学家) can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.
Life requires the right amount and kind of atmosphere. This .eliminates all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it.
Life also requires a steady supply of heat and light. This eliminates double stars, or tars that flare up (闪耀) suddenly. Only single stab that are steady sources of heat and light like our sun would qualify.
Finally, life could evolve only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away.
If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next, eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.
This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.

第5题
根据下列材料,请回答 36~40 题:
The great recession may be over, but this era of high joblessness is probably beginning. Before it ends,
It will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics, our culture, and the character of our society for years.
No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways; they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending.
But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U.S. , lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes.
Income inequality usually falls during a recession, but it has not shrunk in this one. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them--- especially for young people. The research of Till Von Wachter, the economist in Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind.
In the internet age, it is particularly easy to see the resentment that has always been hidden within American society. More difficult, in the moment, is discerning precisely how these lean times are affecting society’s character. In many respects, the U.S. was more socially tolerant entering this recession than at any time in its history, and a variety of national polls on social conflict since then have shown mixed results. We will have to wait and see exactly how these hard times will reshape our social fabric. But they certainly it, and all the more so the longer they extend.
第 36 题 By saying “to find silver linings”(Line 1,Para.2)the author suggest that the jobless try to___.
[A]seek subsidies from the government
[B]explore reasons for the unemployment
[C]make profits from the troubled economy
[D]look on the bright side of the recession
