6、 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.

7、e 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 problems do exist, but well have to start thinking ahead and acting globally

8、. 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 fund to help its farmers get fertilizer and seeds with high productivi

9、ty. 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 their policies of paying partly for the change of food into biofuels. T

10、he 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 productsbut theres no case for the government to pay to put the worlds dinne

11、r 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 weathercan make the difference between a good harvest and a bad one. The wo

12、rld 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.

But if you had been around 15,00

17、0 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 until now, no one has reached a satisfying answer. Rainforests like the A

18、mazon 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 UK each year. But how will the Amazon react to future climate change?

19、 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 change in the past. Unfortunately, getting into the Amazon rainforest a

20、nd 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 specialized equipment and heavy machinery . There are very few roads

21、 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 been drilled that go back to the last ice age and none of them provide

22、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，与mopping up并列的是 “helping to slow global warming”，由此可以推断，mop up 就是去除CO

23、2；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”。2. How will the Amazon rainforest react to future climate change?A. Itll get drier and continue to remove C O 2.B.

24、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 collecting information are very difficult.” 和最后一句 “So far, only a handful o

25、f 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 idea of the last paragraph?A. Its important to drill deep down into lake s

26、ediments 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 specialized equipment and machinery to study the past climate.答案为C。从第三段的最后一句话 “So far, only a handful of cores ha
