问答题 Look at the topic headings below, marked A, B, C, D E, and F, and match them with the paragraphs in the text below. There is one extra heading which you don’t need to use. Questions 1-5 are based on the following passage. A. Decrease in food yields B. Drop in yield affected by reduction in research C. Pollution mining crops D. Desperate situation for Asia E. Population explosion compounds Asia’s problems F. International commerce threatens Asian agricultureWHY WE CAN’T AFFORD TO LET ASIA STARVE Among the problems afflicting a burgeoning world population, overcrowding, poverty and environmental degradation are combining to put at risk the very essence of our survival-food. “If by the beginning of the next century we have failed to satisfy the very basic needs of the two billion very poor and four billion poor, life for the rest of us could be extremely risky and uncomfortable,” predicts Dr. Klaus Lampe of the International Rice Research Institute (IRRI) in the Philippines. This is a highly threatening, even terrifying prediction for Asia, where 70 per cent of the world’s poor live but where reserves of good quality arable land have practically run out. Although the world regards Asia as the focus of an economic and industrial miracle, without adequate supplies of food, Lampe says, chaos could easily result in many countries. And the impact will be felt widely throughout the region. In the 1990s alone, he says, the cities of Asia will be swollen by a further 500 million people—nearly equal to the population of the United States and European Community combined. “The only growing population in Asia is that of the poor. Prime productive land is being used for city expansion and building roads, while thousands of hectares are being taken out of production each year because of salinity or alkalinity.” From the mid-1960s when the Green Revolution began, Asian food production doubled through a combination of highyielding crops, expanded farming area and greater intensification. From now on, growing enough food will depend almost entirely on increasing yield from the same, or smaller, area of land. However, a mysterious threat is emerging in the noticeably declining yields of rice from areas that have been most intensively farmed. Unless scientists can unravel why this is so, food output in Asia may actually stagnate at a time when population will double.Such issues, Lampe argues, while seen as remote by many countries and international corporations, will strike at their economic base as well. Societies that are too poor or driven by internal strife and civil war will be bad for investment or as markets for goods. Pressure from a rising tide of environmental and political refugees may also be felt. One significant factor undermining the agricultural economies of developing countries has been the farm trade war between the US and the EC. “We talk about environmental degradation and dangerous chemicals, yet spend billions of US dollars and ECUs producing things we don’t want which ruin local production systems and incomes for poor people,” Lampe says. And instead of developed countries helping struggling nations to develop sustainable food production systems, their policies tend to erode and destroy them. When world grain prices are bad, farmers in Asia’s uplands turn from rice to cash crops to supplement failing incomes, or clear larger areas of rainforest with catastrophic environmental consequences within just a few years. Cleared rainforest soils are highly erosive; even where they are not, they rapidly become acid and toxic under intense cultivation and plants die, forcing the clearing of ever-larger areas. Research at the IRRI has indicated that intensive rice production-growing two or three crops a year on the same land is showing signs of yield declines as great as 30 per cent. Evidence for this comes from as far a field as India, The Philippines and Indonesia. At the same time, agricultural research worldwide has been contracting as governments, non-government bodies and private donors reduce funding because of domestic economic pressures. This means, Lampe says, that at risk is the capacity to solve such problems as rice yield decline and research to breed the new generation of superyielding crops. Yet rice will be needed to feed more than half the human population—an estimated 4.5 billion out of 8.3 billion people by 2030. Compared with the building of weapons of mass destruction or the mounting of space missions to Mars, Lampe says, the devising of sustainable farming systems has little political appeal to most governments: “To them I say: I hope you can sleep well at night.”
问答题 In this section, there is one passage followed by a summary. Read the passage carefully, and then complete the summary below by choosing a maximum of three words from the passage to fill in each of the blanks. Remember to write the answers on the answer sheet. Questions 1 to 5 are based on the following passage. Everyone knows about pollution in the environment. Water, air, and land are all polluted. This means that pollution is everywhere. Now, scientists are looking inside our bodies to find out about internal pollution. In 2003, the Environmental Working Group studied nine people to measure the chemicals in their bodies. These nine people had an average of 53 cancer-causing chemicals in their bodies. They also had an average of 62 chemicals that can damage the brain, and 55 that can harm babies in pregnant women. Even though a lot of chemicals were found in human bodies, the chemicals were found in small amounts. The amounts were small enough that they were probably not hurting the people. However, scientists are worried because most of these chemicals were created by humans. Most of these chemicals did not exist 75 years ago. This proves that we have not only polluted the world—we have polluted our own bodies! How does this pollution get into our bodies? We come into contact with many chemicals every day. For example, everyone uses soap, skin lotion, and shampoo. However, few people know that these products contain harmful chemicals, some of which may cause memory loss. Chemicals known as DEA (diethanolamine) and TEA (triethanolamine) may seep into the skin and stop us from absorbing a helpful nutrient called “choline”. Choline is a nutrient that plays a crucial role in the memory cell making process in the developing brain. Some people worry that every time we wash our hair, we are decreasing our memories. Everyone knows they should brush their teeth regularly, but recent research has shown that some toothpastes can cause cancer. Fluoride is a key ingredient in many toothpastes. However, studies show that fluoride does not really protect our teeth. In fact, fluoride has been connected with bone cancer and other diseases. While we are trying to save our smiles, we could be damaging our health. Women are probably exposed to more chemicals than men because they use more beauty products. Recently, harmful chemicals have been found in nail polish, hair spray, deodorant, and perfume. The chemicals are called “phthalates”. Studies on animals have shown that phthalates can damage the liver, the kidneys, and the lungs. Cosmetic companies say the amounts of phthalates in their products are safe, but consumer protection groups disagree. They say some women use so many products that the levels are actually high. So, the more women try to look beautiful, the more they could be harming their health. In a futuristic story by Ray Bradbury, a man found a pristine stream on a new planet. When he drank from the stream, he died! Why? His body was so polluted that pure water was a poison to him! Perhaps that is only science fiction, but it reminds us to take care of our bodies. We must find ways to reduce the pollution we absorb. Summary: Like our polluted environment, our bodies are no longer pollution-free. Scientists now know that there is pollution in our bodies. On 1 , we have 53 cancer-causing chemicals in our bodies. Even fluoride 2 with bone cancer and other diseases. Some common cosmetics contain small amounts of chemicals, which seep into our 3 when we use these products. They prevent us from absorbing the 4 our bodies need. So, it is 5 that we find ways to reduce the amount of chemicals in our bodies. We should remind our friends and families to take care of their bodies.

Sugar and water can kill you. Humans and animals are “unable to subsist (9)____ a diet of sugar”. The dead dogs in Professor Magendie’s (10) la____ alerted the sugar industry to the hazards of free scientific inquiry. From that day to this, the sugar industry has invested millions of dollars in behind-the-scenes, subsidized science. The best scientific names that money could buy have been hired, in the hope that they could one day come up with something at least pseudoscientific in the way of glad tidings about sugar.
问答题 Given the choice between spending an evening with friends and taking extra time for his schoolwork, Andy Klise admits he would probably opt for the latter.
