单选题In the preceding chapter, economic welfare was taken broadly to consist of that group of satisfactions and dissatisfactions which can be brought into relation with a money measure. We have now to observe that this relation is not a direct one, but is mediated through desires and aversions. That is to say, the money that a person is prepared to offer for a thing measures directly, not the satisfaction he will get from the thing, but the intensity of his desire for it. This distinction, obvious when stated, has been somewhat obscured for English-speaking students by the employment of the term utility——which naturally carries an association with satisfaction——to represent intensity of desire. Thus, when one thing is desired by a person more keenly than another, it is said to possess a greater utility to that person. Several writers have endeavored to get rid of the confusion which this use of words generates by substituting "utility," in the above sense for some other term, such as "desirability". The term "desiredness" seems, however, to be preferable, because, since it cannot be taken to have any ethical implication, it is less ambiguous. I shall myself employ that term. Generally speaking, everybody prefers present pleasures or satisfactions of given magnitude to future pleasures or satisfactions of equal magnitude, even when the latter are perfectly certain to occur. But this preference for present pleasures does not——the idea is serf-contradictory——imply that a present pleasure of given magnitude is any greater than a future pleasure of the same magnitude. It implies only that our telescopic faculty is defective, and that we, therefore, see future pleasures, as it were, on a diminished scale. That this is the right explanation is proved by the fact that exactly the same diminution is experienced when, apart from our tendency to forget ungratifying incidents, we contemplate the past. Our analysis also suggests that economic welfare could be increased by some rightly chosen degree of differentiation in favor of saving. Nobody, of course, holds that the State should force its citizens to act as though so much objective wealth now and in the future were of exactly equal importance. In view of the uncertainty of productive developments, to say nothing of the mortality of nations and eventually of the human race itself, this would not, even in the extremest theory, be sound policy. But there is wide agreement that the State should protect the interests of the future in some degree against the effects of our irrational discounting and of our preference for ourselves over our descendants. The whole movement for "conservation" in the United States is based on this conviction. It is the clear duty of Government, which is the trustee for unborn generations as well as for its pre sent citizens, to watch over, and, if need be, by legislative enactment, to defend, the exhaustible natural resources of the country from rash and reckless spoliation. Plainly, ff we assume adequate competence on the part of governments, there is a valid case for some artificial encouragement to investment, particularly to investments the return from which will only begin to appear after the lapse of many years. It must, however, be remembered that, so long as people are left free to decide for themselves how much work they will do, interference, by fiscal or any other means, with the way they employ the resources that their work yields to them may react to diminish the aggregate amount of this work and so of those resources.

单选题Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn't know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves. There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth's atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel's report: "Science never has all the answer. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions. " Just as on smoking, voice now come from many quarters insisting that the science about global warming is incomplete; that it's OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the time 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now. Fortunately, the White House is starting to pay attention. But it's obvious that a majority of the president's advisers still don't take global warming seriously. They continue to press for more research, a classic of "paralysis by analysis". To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research. But research alone is inadequate. If the Administration won't take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

单选题{{B}}Passage Five{{/B}} A new look at an asteroid orbiting the sun shows it could possibly smash into the Earth with tremendous force. But experts say the potential impact is still 872 years away, time enough for the speeding space rock to alter its course. Named 1950DA, the asteroid--1 kilometer wide--is the most threatening to the Earth of all of the known large asteroids, but the odds are only adout one in 300 that it would impact the planet, researchers said. "One in 300 is pretty long odds," said Jon D. Giorgini, a scientist in Califonia. "I'm not personally going to worry about it. It is so far in the future that lots of things could change." There are approximately 1,000 asteroids bigger than a kilometer that can pass near the Earth in their orbit of the sun. About 580 have been found and their orbits plotted. Of these, only 1950DA represents a possible threat. Scientists continue an effort to identify all the other large asteroids that pass near the Earth, and it is their great hope that they don't find any that are greater threats. If 1950DA did hit the Earth, said Giorgini, it would have planet-wide effects, setting off fires, changing the weather and perhaps creating immense tidal waves. But it would not be a planet killer like the asteroid thought to have snuffed out the dinosaure some 65 millions years ago. Asteroid 1950DA was first discovered in 1950, but then not noted in astronomy logs again for decades. It was rediscovered in the year 2000 and in March 2001 whizzed within about 77 million miles of Earth, giving astronomers an opportunity to gather visual and radar readings. From that, the astronomers projected the orbital path 1950DA would take on its next 15 near passes of the Earth--over a period covering nearly nine centuries. For the 15th near pass, on March 16,2880, the analysis showed it was mathematically possible, though unlikely, that the asteroid could hit the Earth. He said the highest probability is that the asteroid in 2880 will miss the Earth by about 290, 000 kilometers--a distance closer than the 370, 000-kilometer orbit of the Moon around the Earth.
