Part I Writing (30 minutes)
1．For this part, you are allowed 30 minutes to write a short essay entitled The Damage of E-waste. You should write at least 150 words following the outline given below.1．随着电子设备的增多，电子垃圾也越来越多2．电子垃圾的危害很多3．为此，我们应该……The Damage of E-waste
正确答案：The Damage of E -waste Electronic waste, or e-waste, has become an issue of serious concern to the public as a growing number of electronic items are discarded in landfills every year. Many consumers are not aware that electronics like computers and cell phones actually contain toxins that can leach out into the soil and damage the environment. E-waste compounds pose hazards to the environment as well to the human beings. To start with, when exposed to heat, the components of e-waste release toxic fumes and gas, polluting the air and causing global environmental problems. When circuit breakers deteriorate, they release toxins, such as mercury, that pollute groundwater. In addition to its damaging effect on the environment, researchers have now linked e-waste to adverse effects on human health. In my view, it’s high time that the damage of e-waste should be realized by the public and measures should be taken to cope with this issue. One idea is to put greater responsibility on the companies that produce the goods. It should be mandatory for them to taking the abandoned items back and dispose them in an environmentally-friendly manner.

Genetically Modified Foods—Feed the World? If you want to spark a heated debate at a dinner party, bring up the topic about genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions—and vocal green lobbies—the idea seems against nature. In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the
U. S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U. S. this year. The genetic is out of the bottle. Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from—and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? The statistics on population growth and hunger are disturbing. Last year the world’s population reached 6 billion. And by 2050, the UN estimates, it will be probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world’s available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications (ISAAA).How can biotech help? Biotechnologists have developed genetically modified rice that is fortified with beta-carotene(β-胡萝卜素)—which the body converts into vitamin A—and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi(真菌). Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the world’s corn crops annually, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded. Viruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more than half its cassava(树薯)crop—a key source of calories—to the mosaic virus. Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity(毒性)in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested. Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than 1 dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce. Biotech has its own “distribution” problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won’t even reach the regions where they are most needed.
Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries. More and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on the food production of those countries, there is a need for better collaboration between government agencies—both local and in developed countries—and private biotech firms. The ISAAA, for example, is successfully partnering with the U. S. Agency for International Development, local researches and private biotech companies to find and deliver biotech solutions for farmers in developing countries. Will “Franken-foods” feed the world? Biotech is not a panacea(治百病的药), but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come. The world seems increasingly to have been divided into those who favor genetically modified foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering—which can induce plants to grow in poor soils or to produce more nutritious foods—will soon become an essential tool for helping to feed the world’s burgeoning(迅速发展的)population. Skeptics contend that genetically modified crops could pose unique risks to the environment and to health—risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of genetically modified agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards? Two years ago in Edinburgh, Scotland, eco-vandals stormed a field, crushing canola plants. Last year in Maine, midnight raiders hacked down more than 3,000 experimental poplar trees. And in San Diego, protesters smashed sorghum and sprayed paint over greenhouse walls. This far-flung outrage took aim at genetically modified crops. But the protests backfired; all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for genetically modified varieties. It’s easy to understand why. In a way, genetically modified crops—now on some 109 million acres of farmland worldwide—are invisible. You can’t see, taste or touch a gene inserted into a plant or sense its effects on the environment. You can’t tell, just by looking, whether pollen containing a foreign gene can poison butterflies or fertilize plants miles away. That invisibility is precisely what worries people. How, exactly, will genetically modified crops affect the environment—and when will we notice? Advocates of genetically modified or transgenic crops say the plants will benefit the environment by requiring fewer toxic pesticides than conventional crops. But critics fear the potential risks and wonder how big the benefits really are. “We have so many questions about these plants,” remarks Guenther Stotzky, a soil microbiologist at New York University. “There’s a lot we don’t know and need to find out. “As genetically modified crops multiply in the landscape, unprecedented numbers of researchers have started fanning into the fields to get the missing information. Some of their recent findings are reassuring; others suggest a need for vigilance.

听力原文：By now you may have heard Taylor Swift’s heart-breaking song “Ronan”, about the too-short life of a little boy. Ms. Swift gave it an emotional performance on the Stand Up to Cancer television program on Sept. 7, and it has been topping the charts ever since. The real boy behind the song is Ronan Thompson, a naughty 3-year-old boy from Phoenix with coppery blond hair and big blue eyes. In 2010, a few months after his third birthday, Ronan was given a diagnosis of cancer, an often deadly childhood cancer. He died on May 9, 2011, three days before he was to turn 4. It’s the most common cancer in infants and accounts for about 15 percent of all childhood cancer deaths. Ms. Swift learned about Ronan from a blog that his mother, Maya Thompson, began shortly after the diagnosis to keep family and friends informed. Ms. Thompson called the blog Rockstar Ronan, but she did not tell directly about his illness, and her heartbreak was painfully evident in every update. Ronan spent his last days in a hospital in Phoenix with his parents and brothers. After he died, his mother continued to write tearful posts on her blog, which had turned into an open
letter to her son. Cancer is the second leading cause of death of children under 15—after accidents—yet childhood cancer receives only 3 to 4 percent of national cancer research funds. Although childhood cancer is considered rare, an estimated 12,060 new cases are expected this year among children 14 and younger. The survival rate for childhood cancer is about 80 percent.30. What is Taylor Swift’s song “Ronan”about?31. How did Taylor Swift learn about Ronan?32. What is the first leading cause of children death under 15?

听力原文：Winter is a pain in the animal kingdom. Birds can flee it by migrating to wanner regions but grounded beasts, including mammals, have no choice but to stick around.(33)To cope, many species have learned to spend the winter in a long sleep. Some, like the Columbian ground squirrel, spend up to nine months of each year in their shelters. This conserves energy but leaves them with only three months to become well-rounded for the next winter and, crucially, to reproduce. To make matters worse, climate change is leading them to emerge from winter sleep later than usual.(34)Global warming should mean that the creatures have longer ice-free periods in which to go about their evolutionary tasks. But it can also disturb
weather patterns , which may have the opposite effect. Because female squirrels remain in their place of birth, the researchers were able to tag and observe them and their offspring each year for the past two decades. A typical female would bear three babies. On average, only 30% of them survive the first winter, enough to sustain population numbers since female squirrels can expect three or four litters in their lifetime. If the proportion falls, however, the population reduces. In the first decade of the study the number of squirrels dropped just once. But it fell in four of the past ten years.(35)Dr. Lane, an evolutionary biologist at. the University of Edinburgh, speculates that this might be explained by the fact that over the past 20 years the late snow has delayed the melting of ice by half a day each year, on average, shortening the squirrels’breeding and feeding season by several days and disrupting their life cycles.33. How do many species of animals spend the winter?34. What should global warming mean to the animals?35. What might explain the reduced squirrel population according to Dr. Lane?
30．
A．Sleep for a long time.

听力原文：Movies often depict the elderly as ill-tempered. In fact, most elder people have fewer negative feelings, like anger, than the young. Recent research into how emotions change with age may be able to help people lead healthier
and longer lives and bring about new treatments for depression in the elderly. Like people’s bodies, emotions change over time. Older people for the most part have far fewer negative feelings, such as worry and stress, than do younger people, studies show. The elderly learn to free themselves from feelings of negativity and seem to focus more on present situations that bring pleasure, rather than on the future, researchers say. They also tend to process negative information less deeply than positive information. By contrast, positive feelings such as enjoyment and happiness change very little from the time a person is in his youth until old age. “ It seems to be essential for our emotional well-being to not look back in anger and to focus on the positive when we are older,”Stefanie Brassen, a researcher at the University Medical Center Hamburg-Eppendorf, said in an email. Older people who are depressed seem not to use the sort of emotional regulation typically seen in the elderly, researchers say.(29)Depression affects some six million Americans over the age of 65, or about 15% of the total, and is believed to be a big reason why the elderly have the highest suicide rate, according to the nonprofit Geriatric Mental Health Foundation.26. How are the old like in the movies?27. According to researchers, what do the old pay more attention to?28. What will change less over time when a person is getting old?29.

Since the (36) peak, deaths have fallen by around ten percent as more people have received (37) treatment. Experts credit the good news in the report at least in part to prevention programs, not just the natural progress of the (38) epidemic. Yet the report points out that while the AIDS epidemic is changing, prevention programs are not. Karen Stanecki at UNAIDS says few programs , for example, are designed for people in (39) secure relationships. Or people over twenty-five. Or the newly single. AIDS is the (40) leading cause of death in women aged fifteen to forty-four. Those are the main years for having children. The WHO is now advising (41) infected women to begin anti-ret-roviral (反逆转录病毒的) drugs at fourteen weeks of (42) pregnan-cy, instead of twenty-eight. Women are also advised to continue treatment through the (43) recommended end of breastfeeding, when the baby is one year old. This reduces the risk of infecting the child. Treatments and population growth mean more people than ever are living with HIV. The latest estimates say almost thirty-three and a half million have the virus. There were two million AIDS-related deaths last year, and two million seven hundred thousand new infections. About two-thirds of the people with HTV are in sub-Saharan Africa. On Tuesday, President Jacob Zuma announced an expansion of testing and treatment. By next April, he says, (45) all HIV-infected children less than one year old will receive treatment. AIDS research continues. On Monday the United States said it will hold the 2012 International AIDS Conference. (46) The event has not taken place here since 1990 because of restrictions against visitors with HIV.
