A Sunshade（遮阳伞）for the Planet

Even with the best will in the world,reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time,resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.
Fortunately,if the worst comes to the worst,scientists still have a few tricks up their sleeves.

参考答案

参考解析

解析：题干意思为：通过前两段，作者认为……第一段第一句：Even with the best will in the world , reducing our carbon emissions is not going to prevent global warming．即使怀着世间最美好的愿望，减少碳排放也不会阻止全球变暖。第二段第一句：Fortunately , if the worst comes to the worst , scientists still have a few tricks up their sleeves．幸运的是，如果情况越来越糟，科学家们还有一些应对措施。通过这两句可以明显地看出，作者对限制排放是持反对态度的，认为限排不能解决问题，所以选择B项。
题干意思为：科学家们反对人们对他们的选择进行讨论，因为他们不想让人们知道……第二段第二句：For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem.他们反对人们讨论这些选择的主要原因是担心引起自满情绪，从而使得从根本上解决问题的努力受挫。经过分析，只有C选项正确。
题干意思为：Stephen Schneider提到毒瘾和美沙酮疗法的用意何在？第二段最后一句：If you have a heroin addict , the correct treatment is hospitalization , and a long rehab.But if they absolutely refuse , methadone is better than heroin．如果你有毒瘾，那么最好的方法是住院治疗，进行长时间恢复，但是如果都不管用的话，美沙酮总比海洛因强。显然他是要说明 Methadone is an effective way to treat a hard heroin addict（美沙酮对毒瘾很深的人是有治疗效果的）。因此选项A正确。
题干意思为：Stephen Schneider阻止全球变暖的方法是什么？文中最后一段第一句：Basically the idea is to apply " sunscreen" to the whole planet．这种方法基本上是要为整个地球涂上一层“遮光剂”。经过分析，选项C正确。
题干意思为：根据最后一段，对于遮光剂的有效性的表述，哪一句是错误的？D选项It decreases greenhouse gases in the atmosphere（减少大气层温室气体排放）正好与该方法冲突，所以该项不正确。

考题 EWe already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.Not long age. My wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO2）and other greenhouse gases that are trapping heat in our atmosphere.We decided to try an experiment. For one month we recorded our personal emissions of CO2. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO2 emissions by 80 percent,” he said.Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.72. Why did the author and his wife try a new diet?A. To take special kinds of food B. To respond to climate change.C. To lose weight D. To improve their health

考题 CBusinesses are witnessing a difficult time, which has in turn produced influence on consumers’ edsire to go green . However, shoppers are still laying stress on environmental concerns. Two thirds of customers say that environmental considerations inform. their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy. This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more envitonmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies,with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company’s environmental reputation was not good enough. Harry Morrison, chief executive（主管）of the Carbon Trust, sympathizes：“I understand this situation where survival is very important now. But from environmental considerations, the clocd is ticking—we don’t have much time. In addition, cutting carbon has an immediate effect as costs drop and a mediun-term benefit for the brand.” Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses bo buy carbon allowances to make up for their emissions（排放）. Those that have taken early action will hav e a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers. The Carbon Trust believ es that it can help by informing customers about the good work companies are doing.“When companies are granted（授予）the standard, they can use a logo（标识）in all their marketing which makes it clear that they are working towards cutting emissions,”Mr.Morrison said.64．What’s the main idea of the passage?A．Businesses are finding ways to send their message to the shoppers.B．Companies will soon get information about cutting carbon emissions.C．Firms are making efforts to encourage customers to keep goods at home.D．Firms are urged to cut carbon emissions by shoppers’environmental awareness.
