8、ed farming, describes studies that claim GM crops would be hazardous to Britains wildlife and consumers. This week the government granted permission for a strain of GM maize to be grown commercially as cattle feed. That has incensed environmentalists and organic farmers, who say GM is unpopular (pro

9、bably correct) and based on bad science (probably not). Three years of field testing have shown the herbicide-resistant maize, Bayers Chardon LL, to be safe and even kinder to the environment than non-GM maize. Two other crops on triala GM sugar-beet and a GM oilseed rapewill not be grown because th

10、ey were worse for biodiversity (weeds) than conventional strains. The trials have not made the worries about introducing even a safe GM crop go away, though. Opponents say GM will stealthily take over the country by cross-pollination, will damage wildlife and introduce something nasty into the human

11、 food chain. How solid is all this? Evidence from America, which planted 105.7m acres of biotech crops in 2003, suggests concerns are overblown. In practice it is easy to separate crops and prevent them from cross-pollinating. Even oilseed rape, which is particularly promiscuous, can be kept over 99

12、% pure if it is a hundred metres away from another plantation. Cross-pollination probably will happen, but so far it has caused no problems, genetic material in plants changes all the time through sexual reproduction anyway. Damage to wildlife is difficult to measure, but there is evidence that GM h

13、as had a positive effect, with birds and insects returning to GM cotton plantations in America. Certainly, GM crops tend to need fewer chemicals to protect them. Monsanto says its sugarbeet, which was on trial along with the Chardon maize, requires 46% less herbicide than a conventional strain. Supp

14、osed threats to consumers, whether human or animal, are the most flaky. One recent study appeared to show that Chardon maize could be fatal to cattle, but the heifer in question in fact died from botulism. The British Medical Association now says there is very little potential for GM foods to cause

15、harmful health effects in people either. People have been eating the stuff in America for years, with no ill effects so far. The messing around with genetic material that makes some people dislike GM crops has gone on for years in conventional plant breeding, where crops are exposed to radiation and

16、 chemicals to encourage them to mutate. According to the International Atomic Energy Agency in Vienna, over 2,000 types of crop have been bombarded with gamma rays to produce mutants, many of which are grown by organic farmers. All food is frankenfood, according to Professor Howard Dalton, chief sci

17、entific adviser to the Department for Food and Rural Affairs, but everybodys got used to it. Maybe everybody will get used to GM soon, too. 1. According to the British government,A.genetically modified fanning can be described as junk science.B.GM crops pose hazards to Britains wildlife and consumer

18、s.C.GM food is not favored by the public.D.a kind of GM crop will be grown as animal feed.答案:D解析 细节题。题目问的是“通过英国政府，我们可以了解到什么?”。根据第一段，A项并没有提到，故排除。转基因作物对英国野生动物和消费者有害，这是经过研究发现的，并不是政府公布的的结果，故排除B项。文中只是说转基因食物不受那些环保主义者和有机农民的青睐，并未提及公众都不喜欢，故排除C项。而由第一段第二句“This week the government granted permission for a strai

19、n of GM maize to be grown commercially as cattle feed.”可知政府已经批准可以种植转基因玉米来作为牲畜饲料，故选D。2. Field testing in America has shown thatA.non-GM crops are more environment-friendly than GM crops.B.concerns over the threats of GM crops are exaggerated.C.GM crops pose serious threats to biodiversity.D.cross-pol

20、lination has introduced nasty species into the human food chain.答案:B解析 细节题。题目问的是“美国的田间测试说明了什么?”。由第二段可知，已经有实验证明了存在环境友好型的转基因作物，当然也存在对生物多样性有影响的转基因作物，A、C项太绝对了，故排除。转基因反对者认为，转基因会引入一些不好的东西，这不是田间测试的内容，故排除D项。由第四段第一句“Evidence from America, which planted 105.7m acres of biotech crops in 2003, suggests concerns

21、 are overblown.”可知人们的担忧有些多虑了，故选B。3. The following statements are true EXCEPTA.GM crops are good to wildlife in America.B.conventional crops require more chemicals for protection.C.one study shows that GM crops are harmful to animals.D.GM foods have done no harm to Americans.答案:C解析 细节题。题目问的是“下面哪项是不正确

22、的?”。关于A、B、D四项中的论述，文中第五段都有提到，C项是说研究表明转基因作物对动物会造成伤害，文中并没有明确提到，故选C。4. According to the author, conventional crop breeding hasA.been for a long time exposed to radiation.B.proved much safer than GM crop breeding.C.never been messed around with genetic material.D.produced no ill effects on people so far.

23、答案:C解析 细节题。题目问的是“在作者看来，传统作物种植_。”。文中第六段第一句提到“The messing around with genetic material that makes some people dislike GM crops has gone on for years in conventional plant breeding, where crops are exposed to radiation and chemicals to encourage them to mutate.”，那些青睐传统种植方式的人认为，在射线和化学物质的作用下，转基因作物的遗传物质已经

24、发生了改变，所以相比较而言，种植传统的作物不会出现遗传物质混乱的情况。暴露在射线中的是转基因作物而不是传统作物，故排除A项。有研究表明有些转基因作物存在不安全性，但并不表示传统的农作物就比转基因作物更安全，故排除B项。文中只提到，到目前为止转基因作物并未对人类产生负面影响，并未提到传统的农作物的影响，故排除D项。综上所述，故选C。5. What is the authors attitude towards GM crops?A.Disapproving.B.Neutral.C.Positive.D.Suspicious.答案:C解析 推理题。题目问的是“作者本人对转基因作物持有什么态度?”。

25、文章最后一段最后一句作者提到“Maybe everybody will get used to GM soon, too”，尽管还有人不支持转基因这种做法，但是很快大家都会习惯。再综合全文，可看出作者对转基因这件事还是持赞成态度的，故选C。Text 2 Opinion polls are now beginning to show a reluctant consensus that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This me

26、ans we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm? Should we not rather encourage many other ways for self-respecting people to

27、 work? Should we not create conditions in which many of us can work for ourselves, rather than for an employer? Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work? The industrial age has been the only period of hu

28、man history in which most peoples work has taken the form of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought may have to be reversed. This seems a daunting thought. But, in fact, it could offer the prospect of a better future for work.

29、Universal employment, as its history shows, has not meant economic freedom. Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then

30、 the factory system destroyed the cottage industries and removed work from peoples homes. Later, as transport improved, first by rail and then by road, people commuted longer distances to their places of employment until, eventually, many peoples work lost all connection with their home lives and th

31、e places in which they lived. Meanwhile, employment put women at a disadvantage. In pre-industrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and

32、 family to his wife. Tax and benefit regulations still assume this norm today, and restrict more flexible sharing of work roles between the sexes. It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were excludeda problem now,

33、 as more teenagers become frustrated at school and more retired people want to live active lives. All this may now have to change. The time has certainly come to switch some effort and resources away from the utopian goal of creating jobs for all, to the urgent practical task of helping many people

34、to manage without full-time jobs. 1. Research carried out in recent opinion polls shows that _.A.available employment should be restricted to a small percentage of the populationB.new jobs must be created in order to rectify high unemployment figuresC.available employment must be more widely distrib

35、uted among the unemployedD.the present high unemployment figures are a fact of life答案:D2. The article suggests that we should now re-examine our thinking about the future of work and _.A.be prepared to admit that being employed is not the only kind of workB.create more factories in order to increase

36、 our productivityC.set up smaller private enterprises so that we in turn can employ othersD.be prepared to fill in time at home by taking up hobbies and leisure activities.答案:A3. The arrival of the industrial age in our historical evolution meant that _.A.universal employment virtually guaranteed pr

37、osperityB.economic freedom came within everyones graspC.patterns of work were fundamentally changedD.peoples attitudes to work had to be reversed答案:C4. The enclosures of the 17th and 18th centuries meant that _.A.people were no longer legally entitled to own landB.people were forced to look elsewher

38、e for means of supporting themselvesC.people were not adequately compensated for the loss of their landD.people were badly paid for the work they managed to find答案:B5. The effects of almost universal employment were overwhelming in that _.A.the household and village community disappeared completelyB

39、.men now travelled enormous distances to their places of workC.young and old people became superfluous components of societyD.the work status of those not in paid employment suffered答案:DText 3 The average person sees tens of thousands of images a dayimages on television, in newspapers and magazines,

40、 and on the sides of buses. Images also grace soda cans and T-shirts, and Internet search engines can instantly procure images for any word you type. On Flickr. com, a photo-sharing Web site, you can type in a word such as love and find photos of couples in embrace or parents hugging their children.

41、 Type in terror, and among the results is a photograph of the World Trade Center towers burning. Remember when this was a shocking image? asks the person who posted the picture. The question is not merely rhetorical. It points to something important about images in our culture: they have become less

42、 magical and less shocking. Until the development of mass reproduction, images carried more power and evoked more fear. Today, anyone with a digital camera and a PC can produce and alter an image. As a result, the power of the image has been diluted in one sense, but strengthened in another. It has

43、been diluted by the ubiquity of images and the many populist technologies (like inexpensive cameras and picture-editing software) that give almost everyone the power to create, distort, and transmit images. But it has been strengthened by the gradual surrender of the printed word to pictures. Text c

44、eded to image might be likened to an articulate person being rendered mute, forced to communicate via gesture and expression rather than language. We love images and the democratizing power of technologies that give us the capability to make and manipulate images. What we are less eager to consider

45、are the broader cultural effects of a society devoted to the image. Historians and anthropologists have explored the story of mankinds movement from an oral-based culture to a written culture, and later to a printed one. But in the past several decades we have begun to move from a culture based on t

46、he printed word to one based largely on images. In making images rather than texts our guide, are we opening up new vistas for understanding and expression, creating a new form of communication that is better than print, as some scholars have argued? Or are we merely making a peculiar and unwelcome

47、return to forms of communication once ascendant in preliterate societies? Two things in particular are at stake in our contemporary confrontation with an image-based culture. First, technology has considerably undermined our ability to trust what we see, yet we have not adequately grappled with the

48、effects of this on our notions of truth. Second, if we are indeed moving from the era of the printed word to an era dominated by the image, what impact will this have on culture? Will we become too easily accustomed to verisimilar rather than true things, preferring appearance to reality and in the

49、process rejecting the demands of discipline and patience that true things often require of us if we are to understand their meaning and describe it with precision? 1. The first paragraph of the text tells us thatA.we are exposed to a multitude of images every day.B.consumer goods with images look mo

50、re graceful.C.the Internet can instantly present images of anything we want to buy.D.Internet search engines give us undesired and shocking images.答案:A解析 主旨题。题目问的是“文章的第一段告诉我们什么?”。由文章第一句“The average person sees tens of tens of thousands of images a day”可知：一般来说，每人每天都能看到成千上万张图片，这与A项内容相符。故选A。2. With the

51、 development of mass reproduction, imagesA.have become less important in popular culture.B.are not as impressive as they were to viewers.C.will be more magical and shocking in the future.D.will become more and more thought-provoking.答案:B解析 推理题。题目问的是“随着大量加工技术的发展，图像变得怎么样?”。由文章第三段的第二句“As a result，the p

52、ower of the image has been diluted in one sense, .”可知：因此，图片的力量在某种意义上已经被分解了。从而分析得知图像不再像以前那样对我们有震撼力了，这与B项内容相符。故选B。3. The power of the image has been strengthened in the sense thatA.populist technologies enable almost everybody to manipulate images.B.images have gradually won popularity among common pe

53、ople.C.images are forcing us to communicate via gestures rather than language.D.with populist technologies, texts might give way to pictures gradually.答案:D解析 推理题。题目问的是“图片的力量在某种程度上被强化，是因为_”。由文章第三段的第四句“But it has been strengthened by the gradual surrender of the printed word to pictures.”可知：而它被加强是因为印刷

54、文字逐渐让步于图片，从中我们可以推断出将来图片会逐步取代文字，这与D项内容相符。故选D。4. What does forms of communication once ascendant in preliterate societies (line 4, para. 5) refer to?A.Images.B.Written words.C.Printed images.D.Texts.答案:A解析 推理题。题目问的是“文明前社会的交流形式是指什么?”。由文章第五段第二句“Or are we merely making a peculiar and unwelcome return to

55、forms of communication once ascendant in preliterate societies?”可知：或者我们只是做了一个特殊的，不受欢迎的回归，回归到了文明前社会的交流形式?这里的文明前社会的交流形式指的就是图片。故选A。5. From the text, it can be inferred that the authorA.agrees that images offer a better form of communication than the print.B.does not share the opinion that an image-base

56、d culture is less advanced.C.shows deep concern about the impact of images on culture.D.prefers the image era to that of the printed word.答案:C解析 推理题。题目问的是“从文中可推论出作者_”。由文章倒数第二句话“Second, if we are indeed moving from the era of the printed word to an era dominated by the image, what impact will this ha

57、ve on culture?”可知：其次，如果我们确实是从印刷文字的时代，转变到了图像为主的时代，那么会给文化带来什么样的影响呢?从中可推断出作者对于图片对于文化的影响而感到担心，这与C项内容相符。故选C。Part B Supermarket shoppers have never been more spoilt for choice. But just when we thought traditional systems of selective farming had created the most tempting array of foods money can buy, we are now being presented with the prospect of genetically created strains of cabbages, onion, tomato, potato and apple. It may not tickle the fancy of food purists but
