Genetically Modified Foods--Feed the World?
[A] 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.
[B] 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.
[C] 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?
[D] 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?
[E] Biotechnologists have developed genetically modified rice
that is fortified with beta-carotene(胡萝卜素)--which the body

We say we want only the best, but we strangely enjoy junk food. We’re 2 with health and weight loss but face an unprecedented epidemic of obesity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物) wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more 4 ways of doing it. The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be 5 by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles. Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sit ins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political 6 . But strong opinions have not brought 7 . Americans are ambivalent about what they put in their mouths. We have become 8 of our foods, especially as we learn more about what they contain. The 9 in food is still prosperous in the American consciousness. It’s no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage(束缚). It’s w hat we eat—and how we 10 it with friends, family, and strangers—that help define America as a community today.

2015大学英语六级阅读模拟试题及答案
大学英语六级阅读模拟试题及答案 第一篇 A scientific panel convened by the World Health Organization recommended guidelines on Friday for doctors conducting clinical studies of SARS patients. The panel urged doctors to apply the guidelines in analyzing the masses of potentially useful information about various therapies that were collected in this year’s epidemic. Much of that information has not been published or analyzed. “It is a matter of urgency to get better analysis and review,” said Dr. Simon Mardel, a WHO official who led the two-day meeting that ended on Friday. He said thousands of potential therapies and compounds had been tested so far as researchers try to determine treatments for SARS, or severe acute respiratory syndrome. “We recognize that having no treatment for SARS is hindering our ability to control an epidemic in so many ways.” He said. In the epidemic earlier this year, various treatments, like drugs to fight the virus or strengthen the immune system, as well as traditional Chinese medicine, were delivered under emergency conditions, in widely different settings and countries to patients suffering from varying stages of the illness. Those conditions—generally without standardized measurements or controlled situations—have made it hard to interpret results. Standard supportive therapy like nursing, and in severe cases the use of mechanical respirators（呼吸器）to help patients breathe, is the mainstay（主要支持）of SARS care, and helped many patients survive. But doctors still do not know how best to treat SARS patients who have breathing difficulties. Dr. Mardel said. One method is invasive ventilation. A second method involves blowing oxygen into the lungs through a mask. Both carry the risk of transmitting the virus to hospital employees. Without proper analysis, the panel was unable to say definitively which treatment worked best, or which caused the most harm. “There is a lack of shared information,” Dr. Mardel said, noting that a lot of data have not been published. The panel also agreed on guidelines that would allow doctors to conduct quick and safe clinical trials, a process that generally takes years to complete. The world Health Organization, a United Nations agency did not release the guidelines. Dr. Mardel said they were flexible because no one knew where, when and in what setting SARS would return. Experts in many countries have already listed the treatments they want to test, and the health agency is leaving these decisions to individual nations. 1. Guidelines recommended by the scientific panel can be used for _____. A. gathering potentially useful information about various therapies collected B. conducting clinical studies of SARS patients C. determining treatment for SARS D. publishing all the information about SARS

2014年12月大学英语六级长篇阅读匹配1 It's Time to Pay Attention to Sleep A. After being diagnosed with brain and lung cancer in 2011, Lynn Mitchell, 68, was averaging about an hour of solid sleep a night. Stressed about her treatments, she was paying for it in hours of lost sleep. B. The brain cancer was already affecting her mobility--Mitchell was often dizzy and would lose her balance--but the lack of sleep made things worse. Even walking became increasingly difficult. Exhausted in the mornings, she was practically incoherent (精神恍惚). When her doctors recommend she see a sleep therapist, Mitchell was relieved at how benign it sounded in comparison to the chemotherapy (化学疗法)she had undergone and the gene therapy trial she was undergoing, which had side effects like nausea and fatigue. C. For about nine weeks, Mitchell worked with the sleep therapist to adjust her sleep habits. She went to bed only when she was extremely fired. She quit watching TV in bed. She stopped drinking caffeinated (含咖啡因的) coffee in the evening. She also learned breathing exercises to relax and help her fall asleep. It was all quite simple and common sense, and most importantly, noninvasive and didn't require taking any pills. D. "It's common knowledge that sleep is needed for day to day function," says Dr. David Rapoport, director of the Sleep Medicine Program at NYU School of Medicine. "What isn't common knowledge is that it really matters--it's not just cosmetic." Rapoport has long seen people seek sleep therapy because they're chronically fired or suffering from insomnia, but an increasing number of patients are being referred to his center for common diseases, disorders, and mental health. E. Researchers have known for some time that sleep is critical for weight maintenance and hormone balance. And too little sleep is linked to everything from diabetes (糖尿病) to heart disease to depression. Recently, mounting evidence indicates that sleep plays a role in nearly every aspect of health. Beyond chronic illnesses, a child's behavioral problems at school could be rooted in mild sleep apnea (呼吸暂停). And studies have shown children with ADHD (注意力缺陷多动症) are more likely to get insufficient sleep. A recent study published in the journal SLEEP found a link between older men with poor sleep quality and cognitive decline. Another study shows sleep is essential in early childhood for development, learning, and the formation and retention of memories. F. But to many of us, sleep is easily sacrificed, especially since lack of it isn't seen as life threatening.Over time, sleep deprivation can have serious consequences, but we mostly sacrifice a night of sleep here and there, and always say that we'll "catch up." Luckily, it is possible to make up for sleep debt (though it can take a very long time), but most Americans are still chronically sleep deprived.

2014年大学英语六级阅读专项练习(1) I live in the land of Disney，Hollywood and year-round sun. You may think people in such a glamorous，fun-filled place are happier than others. If so，you have some mistaken ideas about the nature of happiness. Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper，more abiding emotion. Going to an amusement park or ball game，watching a movie or television，are fun activities that help us relax，temporarily forget our problems and maybe even laugh. But they do not bring happiness，because their positive effects end when the fun ends. I have often thought that if Hollywood stars have a role to play，it is to teach us that happiness has nothing to do with fun. These rich，beautiful individuals have constant access to glamorous parties，fancy cars，expensive homes，everything that spells “happiness”。But in memoir after memoir，celebrities reveal the unhappiness hidden beneath all their fun：depression，alcoholism，drug addiction，broken marriages，troubled children and profound loneliness. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he‘s honest，he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun，adventure and excitement. Marriage has such moments，but they are not its most distinguishing features. Similarly，couples that choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out ever they want and sleep as late as they want. Couples with infant children are lucky to get a whole night‘s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to. It liberates time：now we can devote more hours to activities that can genuinely increase our happiness. It
大学英语六级阅读理解及答案
Reading Comprehension for CET 6 Passage 1 In the 1962 movie Lawrence of Arabia,one scene shows an American newspaper reporter eagerly snapping photos of men looting a sabotaged train.One of the looters,Chief Auda abu Tayi of the Howeitat clan,suddenly notices the camera and snatches it.Am I in this?he asks,before smashing it open.To the dismayed reporter,Lawrence explains,He thinks these things will steal his virtue.He thinks you're a kind of thief. As soon as colonizers and explorers began taking cameras into distant lands,stories began circulating about how indigenous peoples saw them as tools for black magic.The ignorant natives may have had a point.When photography first became available,scientists welcomed it as a more objective way of recording faraway societies than early travelers' exaggerated accounts.But in some ways,anthropological photographs reveal more about the culture that holds the camera than the one that stares back.Up into the 1950s and 1960s,many ethnographers sought pure pictures of primitive cultures,routinely deleting modern accoutrements such as clocks and Western dress.They paid men and women to re-enact rituals or to pose as members of war or hunting parties,often with little regard for veracity.Edward Curtis,the legendary photographer of North American Indians,for example,got one Makah man to pose as a whaler with a spear in 1915--even though the Makah had not hunted whales in a generation. These photographs reinforced widely accepted stereotypes that indigenous cultures were isolated,primitive,and unchanging.For instance,National Geographic magazine's photographs have taught millions of Americans about other cultures.As Catherine Lutz and Jane Collins point out in their 1993 book Reading National Geographic,the magazine since its founding in 1888 has kept a tradition of presenting beautiful photos that don't challenge white,middle-class American conventions.While dark-skinned women can be shown without tops,for example,white women's breasts are taboo.Photos that could unsettle or disturb,such as areas of the world torn asunder by war or famine,are discarded in favor of those that reassure,to conform with the society's stated pledge to present only kindly visions of foreign societies.The result,Lutz and Collins say,is the depiction of an idealized and exotic world relatively free of pain or class conflict. Lutz actually likes National Geographic a lot.She read the magazine as a child,and its lush imagery influenced her eventual choice of anthropology as a career.She just thinks that as people look at the photographs of other cultures,they should be alert to the choice of composition and images. 1.The main idea of the passage is______________. [A]Photographs taken by Western explorers reflect more Westerners’ perception of the indigenous cultures and the Western values. [B]There is a complicated relationship between the Western explorers and the primitive peoples. [C]Popular magazines such as National Geographic should show pictures of the exotic and idealized worlds to maintain high sales. [D]Anthropologists ask the natives to pose for their pictures,compromising the truthfulness of their pictures. 2.We can infer from the passage that early travelers to the native lands often_________. [A]took pictures with the natives [B]gave exaggerated accounts of the native lands

在将题目和文章比对的同时，要善于学会精读重点信息。比如，文中举例处，引语及多个名词并列而不是完整句子的内容，均可略读。此外，要多关注文中的逻辑关系词，对于这些词的把握，有助 于我们精确把握重要信息。通常要注意下面三种逻辑关系： (1)并列、递进关系：and，or，besides，furthermore， what’smore，then，inaddition，moreover，inotherwords; (2)因果关系：asaresultof，onaccountof，asaresult，thanksto，therefore，hence，consequently，because，for，dueto，owingto; (3)转折关系：whereas，however，but，nevertheless，yet，infact; 最后，要学会运用特殊的标点符号，比如冒号，破折号，小括号。这些标点符号的出现就是对前面的内容作进一步的说明。所以，在 阅读文章时，可以跳读这些标点符号后面的信息，从而帮助我们节 省更多宝贵的时间并且更加快速地把握文章的主旨。 妙招之三，精炼原文，学会概括。 1、扩充词汇量 2、学会对六级不同考试题目的理解
2019大学英语六级阅读专项练习10
2019大学英语六级阅读专项练习10 The word religion is derived from the Latin noun religio, which denotes both earnest observance of ritual obligations and an inward spirit of reverence. In modern usage, religion covers a wide spectrum of meaning that reflects the enormous variety of ways the term can be interpreted. At one extreme, many committed believers recognize only their own tradition as a religion, understanding expressions such as worship and prayer to refer exclusively to the practices of their tradition. Although many believers stop short of claiming an exclusive status for their tradition, they may nevertheless use vague or idealizing terms in defining religion for example, true love of God, or the path of enlightenment. At the other extreme, religion may be equated with ignorance, fanaticism, or wishful thinking. By defining religion as a sacred engagement with what is taken to be a spiritual reality, it is possible to consider the importance of religion in human life without making claims about what it really is or ought to be. Religion is not an object with a single, fixed meaning, or even a zone with clear boundaries. It is an aspect of human experience that may intersect, incorporate, or transcend other aspects of life and society. Such a definition avoid the drawbacks of limiting the investigation of religion to Western or biblical categories such as monotheism (belief in one god only) or to church structure, which are not universal. For example, in tribal societies, religion unlike the Christian church usually is not a separate institution but pervades the whole of public and private life.

We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons rather than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or of having their idea stolen. These people who seem lazy may be ruined by a fear of failure that prevents fruitful work. Or other sorts of fantasies (幻想) may prevent work; some people are so busy planning, sometimes planning great deals of fantastic achievements that they are unable to deal with whatever "lesser" work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating rescheduling their day.
