Question

                                         C 

                 Genetically modified (GM) foods (转基因食品) 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(饮食)

本文是议论文。文章主要报道了科学家们针对转基因食物进行辩论的情况。

29. C. 写作目的题。文章第一段提出转基因食物产生的原因并在最后连续提了 四个问题，表示人们对其的担忧，从而引出讨论的话题。

30. D. 细节理解题。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，科学家争论的焦点是转基因食物对人类健康及环境的影响。

31. C. 细节理解题。由第四段中的Four scientists recently took on those questions in a debate,facing off two against two可知，这是一次四位科学家两两一组面对面的辩论。

32. C. 细节理解题。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%的观众支持获胜方的观点。
