1、阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。The 2012 London Olympics had enough problems to worry about. But one more has just been addeda communications blackout caused by solar storms.After a period of calm within the Sun,scientists have detected the signs of a fresh cycle of sunspots that could peak in
2、2012,just in time for the arrival of the Olympic torch in London.Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth,causing strong solar storms that could jam the telecommunications satellites and internet
3、 links sending live Olympic broadcast from London.“The Suns activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites,“ said Professor Richard Harrison,head of space physics at the Rutherf
4、ord Appleton Laboratory in Oxfordshire.At the peak of the cycle,violent outbursts calledcoronal mass ejections(日冕物质抛射) occur in the Suns atmosphere,throwing out great quantities of electrically-charged matter. “A coronal mass ejection can carry a billion tons of solar material into space at over a m
5、illion kilometres per hour. Such events can expose astronauts to a deadly amount,can disable satellites,cause power failures on Earth and disturb communications,” Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.Next week in America,
6、NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory(SDO),which will take images of the Sun that are 10 times clearer than the most advanced televisions available.The Rutherford Appleton Laboratory helped to make the high-tech cameras that will
7、capture images of thesolar flares(太阳耀斑) and explosions as they occur.Professor Richard Holdaway,the labs director,said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth. “If we have advance warning,well be able t

12、n into a brick wall. Despite countless warnings in recent years about the need to address a potential hunger crisis in poor countries and an energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the pas
13、t two years. And oil prices have increased more than three times since the start of 2004. These food-price increases, combined with increasing energy costs, will slow if not stop economic growth in many parts of the world and will even affect political stability. Practical solutions to these problem
14、s do exist, but well have to start thinking ahead and acting globally. Here are three steps to ease the current food crisis and avoid the potential for a global crisis. The first is to promote the dramatic success of Malawi, a country in southern Africa, which three years ago established a special f
15、und to help its farmers get fertilizer and seeds with high productivity. Malawis harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion altogether. Second, the U. S. and Europe should abandon th
16、eir policies of paying partly for the change of food into biofuels. The U. S. government gives farmers a taxpayer-financed payment of 51 cents per gallon of ethanol(乙醇) changed from corn. There may be a case for biofuels produced on lands that do not produce foodstree crops, grasses and wood product
17、sbut theres no case for the government to pay to put the worlds dinner into the gas tank. Third, we urgently need to weather-proof the worlds crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pondwhich collects rainwater to be used in dry weathe
18、rcan make the difference between a good harvest and a bad one. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise. 1. An international fu

With the
20、second step, the author expresses the idea that.A. it is not wise to change food crops into gasB. it is misleading to put tree crops into the gas tankC. we should get alternative forms of fuel in any wayD. biofuels should be developed on a large scale3. Which of the following is true according to th
21、e passage? A. A rain-collecting pond is a simple safeguard against by weather.B. A Climate Adaptation Fund has been established to help poor regions.C.

23、 it is steamy, warm, damp and thick. But if you had been around 15,000 years ago, during the last ice age, would it have been the same? For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted（反应）to the cold, dry climates of the ice ages, but unti
24、l now, no one has reached a satisfying answer. Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming. Currently the trees in the Amazon take in around 500 million tones of CO2 each year; equal to the total amount of CO2 giving off in the
25、UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ? Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate ch
26、ange in the past. Unfortunately, getting into the Amazon rainforest and collecting information are very difficult. To study past climate, scientists need to look at fossilized pollen, kept in lake muds. Going back to the last ice age means drilling deep down into lake sediments （沉淀物）, which requires
27、 specialized equipment and heavy machinery . There are very few roads and paths, or places to land helicopters and aeroplanes. Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled（未取样）. So far, only a handful of cores have be
28、en drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change. 1. The underlined phrase “mopping up” in the second paragraph means _.A. cleaning up B. taking in C. wiping out D. giving out 答案解析：答案为B。本题为词义推断题。结合上下文，
29、与mopping up并列的是 “helping to slow global warming”，由此可以推断，mop up 就是去除CO2；并且后面的 “Currently the trees in the Amazon take in around 500 million tones of CO2 each year”中的 “take in” 也对此进行了呼应，故答案为B。“clean up”意为 “清洁”； “wipe out” 意为 “消灭，彻底摧毁”； “give out”意为“分发，散发”。来源:2. How will the Amazon rainforest react to
30、future climate change?A. Itll get drier and continue to remove C O 2.B. Itll remain steamy, warm, damp and thickC. Itll get warmer and then colder and drier.D. There is no exact answer up to present.答案解析：答案为D。本题为细节题。第二段提出问题，第三段进行探索问题。结合第三段首句 “Unfortunately, getting into the Amazon rainforest and col
31、lecting information are very difficult.” 和最后一句 “So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.” 可知，收集信息非常困难，即使目前收集到的一点信息也没有哪一点可以作出证明。故答案为D。3. Whats the main id
32、ea of the last paragraph?A. Its important to drill deep down into lake sediments to collect information.B. Its impossible to prove how climate changes in the Amazon rainforest.C. Its hard to collect information for studies of the past climate in the Amazon rainforest.D. Its necessary to have special
33、ized equipment and machinery to study the past climate. 答案解析：答案为C。从第三段的最后一句话 “So far, only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.” 可知，答案为C。B选项显得绝对。4. The best title
34、 for this passage may probably be_.A. Studies of the Amazon B. Climates of the AmazonC. Secrets of the Rainforests D. Changes of the Rainforests答案解析：答案为C。 本文第一段前两句提出问题，第三句话引入文本的讨论点：热带雨林的变化。下文以亚马逊热带雨林为例进行研究，最终发现很难收集资料去证明热带雨林的变化，热带雨林的秘密有待人们去探索。故答案为C。本文的重心是在讨论如何收集到足够的证据来证明热带雨林的变化，而不是揭示热带雨林有何变化。故排除干扰性最强
