Question

                                         C 

                 Genetically modified (GM) foods (轉(zhuǎn)基因食品) have been around for many years. They are developed for a number of different reasons — to fight disease,resist pests,improve nutrition,survive drought — and are mainly found in our food supply in processed foods using com,soybeans and as feed for farm animals. Are they safe? How do they affect the environment? Can they improve food security? Is the world better off with or without GM foods?

                 Supporters of GM foods say that farmers who grow these crops are able to use fewer environmentally damaging farm chemicals. The increased output is important to feeding the world's growing population. And many studies have shown that GM foods are safe to eat and that there's no actual evidence of any health risks. They also add that the oods have been thoroughly examined and have gamed approval for eating from a wide variety of government and scientific bodies.

                 Critics,however,are concerned that these foods have not been strictly tested and are potentially dangerous for both the environment and people's health. They say farmers growing GM crops have actually increased their use of farm chemicals. And the widespread use of the crops,they say,has also led to an increase in weeds and insects that have resistance to farm chemicals. And,they argue,there is still no scientific evidence of the long-term safety of these foods.

                 Four scientists recently took on those questions in a debate,facing off two against two on GM foods. In these Oxford-style debates,the team that gets the most people on its side by the end is the winner.

                 Before the debate,the audience at the Kaufman Music Center in New York voted 32 percent in favor of GM foods,with 30 percent against and 38 percent undecided. Afterward,60  percent agreed with GM foods,and 31 percent disagreed — making the side arguing in favor of GM foods the winners of this debate.

C篇(飲食)

本文是議論文。文章主要報道了科學(xué)家們針對轉(zhuǎn)基因食物進(jìn)行辯論的情況。

29. C. 寫作目的題。文章第一段提出轉(zhuǎn)基因食物產(chǎn)生的原因并在最后連續(xù)提了 四個問題，表示人們對其的擔(dān)憂，從而引出討論的話題。

30. D. 細(xì)節(jié)理解題。由第二段中的use. fewer environmentally damaging farm chemicals,GM foods are safe to eat and that there's no actual evidence of any health risks 和第三段的 are concerned that these foods have not been strictly tested and are potentially dangerous for both the environment and people's health 可知，科學(xué)家爭論的焦點(diǎn)是轉(zhuǎn)基因食物對人類健康及環(huán)境的影響。

31. C. 細(xì)節(jié)理解題。由第四段中的Four scientists recently took on those questions in a debate,facing off two against two可知，這是一次四位科學(xué)家兩兩一組面對面的辯論。

32. C. 細(xì)節(jié)理解題。由最后一段中的 Afterward,60 percent agreed with GM foods ... making the side arguing in favor of GM foods the winners of this debate 可知，60%的觀眾支持獲勝方的觀點(diǎn)。
