23、re enough to decide what to do about global warming.As arguments over the science behind climate change have cooled, the question of how much nations should be willing to pay has come to dominate the debate. Now Martin Weitzman has developed the first thorough method for including unlikely but extre

24、me events in cost-benefit analyses. When you take into account extreme temperature rises of more than around 6, he says, they dominate all other options and effectively demand that investment aimed at stopping them be made now.Economists say that such events are theoretically possible but are so unl

25、ikely and lie so far in the future that it is not cost-effective to spend money to prevent them. Computer models also suggest that using more renewable energy and reducing emissions in other ways would almost certainly avoid extreme temperature increases. But Weitzmans results are so dramatic that s

26、ome economists, many of whom argued in favour of caution, are shifting their position.Environmental groups argue that the risk of extreme events justifies large investment now, but other groups, notably industry-orientated think tanks and many Republican politicians, have resisted such calls. “In th

27、e United States, cost-benefit analyses have been used to back up questions about whether investment is worth much mow,“ says Grubb. “This throws a pretty fundamental spanner in the works.“The new method also backs up the conclusions of the Stern Review on the Economics of Climate Change, albeit via

28、different methods. Stems cost-benefit analysis, which was published in October 2006, did not consider extreme events. Even so, he found that the benefits of investing now would be enormous: The world could save $2.5 trillion a year if the rise in CO2 was halted at levels around 50 percent greater th

29、an today. But when Stern put a price on the damages that rising temperatures could cause, he valued future costs in todays money. Many economists, including Weitzman, criticized that assumption, arguing that it ignores the fact that investments made now are expected to be worth more in the future.Th

30、e debate remains unresolved, as ethical arguments continue to rage about how to value future generations. But Weitzmans study shows that once extreme evens are included, the argument becomes irrelevant. This is because the potential cost of extreme evens is so great that they come to dominate the as

31、sessment of risk, whatever method is used to compare the value of present and future generations. “Weitzmans work would have received substantial attention in the Stem report. He would have used it as supporting evidence.“ Says Grubb.Weitzman could also create a headache for policy-makers. The analy

32、sis shows that traditional cost-benefit calculations are getting it wrong, but it does so only by providing that extreme events dominate the costs when included in the calculations. It cannot put a figure on how much should be spent now, unlike the old techniques.（分数：5.00）(1).What does Weitzmans new

33、 method suggest?（分数：1.00）A.It is more sophisticated than traditional cost-benefit analysis.B.It takes ethical assumptions into calculating the amount of investment.C.Extreme events should be considered in cost-benefit analysis.D.It tells us that we should take the problem much more seriously.(2).Why

34、 have economists ignored extreme events when doing cost-benefit analysis?（分数：1.00）A.They think Weitzmans assumption deliberately exaggerates the possibility.B.They think increasing investment now will not be worthwhile.C.They believe extreme temperature rise can be avoided.D.They work for industrial

35、 corporations and Republics.(3).What does the last sentence in paragraph 4 mean?（分数：1.00）A.Weitzmans report caused unexpected problem to investment choices.B.Weitzmans report does not concur with industrial think tanks.C.Weitzmans report doesnt support conventional analysis in the United States.D.We

36、itzmans report has successfully convinced many economists.(4).Which statement is right in comparing Weitzman and Stems report?（分数：1.00）A.Stem and Weitzman used different methods but reached similar conclusion.B.Stem valued the damages caused by rising temperature but Weitzman didnt.C.Both Stern and

37、Weitzman valued the money that should be invested now.D.Both Stem and Weitzman valued future generations in their analysis.(5).Why did Weitzmans report cause trouble for policy-making organs?（分数：1.00）A.They didnt like to spend that much money on global warming.B.They were put under pressure by Weitz

When 3.500 individuals professionally devoted to this

39、proposition are gathered under one roof, as happened at the 20th World Congress of Philosophy in Boston this week. the effect may be more of Babel than of 18th-gentury discourse. Modern philosophy speaks a bewildering variety of languages, from analytic logic to existentialism, poststructuralism, se

40、miotics and the wilder shores of ecofeminism, and there is a fair degree of apartheid between its practitioners.Hence the temptation to view the discipline as too rarefied and “academic“ for mere mortals.Britons are notoriously wary of theory; the national prejudice is well captured by Kiplings “If

41、you can think and not make thoughts your master .“ Isaiah Berlin captured British hearts with his tongue-in-cheek remark that he had turned to political thought because “philosophy can only be done by very clever people“. This is one of the few European countries where almost no school teaches philo

42、sophy. Yet in this age of uncertainty, when todays vocational training may be tomorrows passport to redundancy, “dare to think“ should be the motto pinned on the wall of every undergraduate room and recruitment agency. Philosophy is making a modest comeback in British universities, and not before ti

43、me.The great virtue of philosophy is that it teaches not what to think, but how to think. It is the study of meaning, of the principles underlying conduct, thought and knowledge. The skills it hones are the ability to analyse, to question orthodoxies and to express things clearly. However arcane som

44、e philosophical texts may beand not everybody can come to grips with the demands of Austrian logical positivismthe ability to formulate questions and follow arguments is the essence of education.It can also be studied at many levels. In the US, where the number of philosophy graduates has increased

45、by 5 per cent a year during the 1990s, only a very few go on to become philosophers. Their employability, at 98.9 per cent, is impressive by any standard. Philosophy has always been a good training for the law; but it is equally useful for computer scientists. In this country, the Higher Education S

46、tatistics Survey puts philosophy of science right up with medicine in its employment record for graduates.Philosophy is, in commercial jargon, the ultimate “transferable work skill“. That is not the only argument for expanding philosophy departments and encouraging sixth-formers to read Plato, or Jo

Lecturing the Confederation of British Industry on the “sly utilitarianism“ of employers, he defends a liberal education as needing “no justification beyond the satisfaction and enjoyment that it brings“.
