Cultivating a love of movement can help you get beyond the concept of physical fitness as separate from (34) fitness, and toward a lifelong program of good health through mind and body fitness.Whether you choose yoga or another (35) of movement for exercise, remember that our b

21、： 0.00)八、 Text 1(总题数： 1，分数： 5.00)“It doesnt matter what ethical assumptions you use,“ says Michael Grubb, an expert on climate change policy, cold financial arguments are enough to decide what to do about global warming.As arguments over the science behind climate change have cooled, the question of

22、 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 extreme events in cost-benefit analyses. When you take into account extreme temperature rises of more than around 6, he says, they domina

23、te 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 unlikely and lie so far in the future that it is not cost-effective to spend money to prevent them. Computer models also suggest that u

24、sing more renewable energy and reducing emissions in other ways would almost certainly avoid extreme temperature increases. But Weitzmans results are so dramatic that some economists, many of whom argued in favour of caution, are shifting their position.Environmental groups argue that the risk of ex

25、treme events justifies large investment now, but other groups, notably industry-orientated think tanks and many Republican politicians, have resisted such calls. “In the United States, cost-benefit analyses have been used to back up questions about whether investment is worth much mow,“ says Grubb.

26、“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 different methods. Stems cost-benefit analysis, which was published in October 2006, did not consider extreme events. Even so, he fo

27、und 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 than today. But when Stern put a price on the damages that rising temperatures could cause, he valued future costs in todays money. Ma

28、ny 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.The debate remains unresolved, as ethical arguments continue to rage about how to value future generations. But Weitzmans study shows

29、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 assessment of risk, whatever method is used to compare the value of present and future generations. “Weitzmans work would have receive

30、d 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 analysis shows that traditional cost-benefit calculations are getting it wrong, but it does so only by providing that extreme events domi

31、nate 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 method suggest?A It is more sophisticated than traditional cost-benefit analysis.B It takes ethical assumptions into calculating t

32、he 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.（分数： 1.00）A.B.C.D.(2).Why have economists ignored extreme events when doing cost-benefit analysis?A They think Weitzmans assumption deliberately ex

33、aggerates 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 corporations and Republics.（分数： 1.00）A.B.C.D.(3).What does the last sentence in paragraph 4 mean?A Weitzmans report caused unexpec

34、ted 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 Weitzmans report has successfully convinced many economists.（分数： 1.00）A.B.C.D.(4).Which statement is right in comparing Weit

35、zman and Stems report?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 Weitzman valued the money that should be invested now.D Both Stem and Weitzman valued future generations in their

36、 analysis.（分数： 1.00）A.B.C.D.(5).Why did Weitzmans report cause trouble for policy-making organs?A They didnt like to spend that much money on global warming.B They were put under pressure by Weitzmans report.C They still cant decide how much they should invest.D They dont know if they can trust the

37、validity of Weitzmans report.（分数： 1.00）A.B.C.D.九、 Text 2(总题数： 1，分数： 5.00)No people doubt the fundamental importance of mothers in child rearing, but what do fathers do? Much of what they contribute is simply being the second adult in the home. Bringing up children is demanding, stressful and exhaust

38、ing. Two adults can support and make up for each others deficiencies and build on each others strength.As we all know, fathers also bring an array of unique qualities. Some are familiar: protector and role model. Teenage boys without fathers are notoriously prone to trouble. The pathway to adulthood

39、 for daughters is somewhat easier, but they must still learn form their fathers, in ways they cannot from their mothers, such as how to relate to men. They learn from their fathers about heterosexual trust, intimacy and difference. They learn to appreciate their own femininity from the one male who

40、is most special in their lives. Most important, through loving and being loved by their fathers, they learn that they are love-worthy.Current research gives much deeper- and more surprising insight into the fathers role in child rearing. One significantly overlooked dimension of fathering is play. F

41、rom their childrens birth through adolescence, fathers tend to emphasize game more than caretaking. The fathers style of play is likely to be both physically stimulating and exciting. With older children it involves more teamwork, requiring competitive testing of physical and mental skills, ff frequ

42、ently resembles a teaching relationship: come on, let me show you how. Mothers play more at the childs level. They seem willing to let the child directly play.Kids, at least in the early years, seem to prefer to play with daddy. In one study of （分数： 5.00）(1).The first paragraph points out that one o

44、aph 3, one significant difference between the fathers and mothers role in child rearing is _.A. the style of play encouragedB. the amount of time availableC. the strength of emotional tiesD. the emphasis of intellectual development（分数： 1.00）A.B.C.D.(3).Which of the following statements is true?A. Mo

45、thers tend to stress personal safety less than fathers.B. Boys are likely to benefit more from their fathers caring.C. Girls learn to read more quickly with the help of their fathers.D.

46、ement on child rearing show that _.A. this improves kids mathematical and verbal abilitiesB. the more time spend with kids, the better they speakC. the more strict the fathers are, the cleverer the kidsD. girls usually do better than boys academically（分数： 1.00）A.B.C.D.(5).The writers main point in w

47、riting this article is _.A. to warn society of increasing social problemsB. to focus the fathers role in the familyC. to discuss the responsibilities of fathersD. to show sympathy for one-parent families（分数： 1.00）A.B.C.D.十、 Text 3(总题数： 1，分数： 5.00)Letter-writing goes back thousands of years but heated up during the Middle Ages and Renaissance.
