　　英語六級閱讀理解基礎練習：

　　In Brazil, the debate over genetically modified organisms, or GMOs, affects mostly soybean production. Brazil is the world's second largest producer of soybeans behind the United States and ahead of Argentina. Most European and Asian retailers want to remain GM free.

　　Non-governmental organizations ***NGOs*** in Brazil are going on a media offensive to prevent the legalization of genetically modified crops. Environmentalists and consumer groups for years have been able to thwart government and companies' attempts to legalize altered food. In radio dramas that are being broadcast in remote regions, Brazilian NGOs are telling soy farmers the use of genetically modified seeds could endanger their health, their fields and their business. "We are not saying that genetic engineering is, in principle, something bad; we say that we need more science to be sure that it will work in an appropriate way with no harm in the future," said campaign coordinator Jean-Marc von der Weid. "This is both for health and environmental reasons. The other question is on economics. What we think is that in Brazil, if we approve the GMOs, we will lose a spectacular advantage that we have now. We are selling more to the international market, mostly for Europe and Asia, than we have done in our history, because we are not GMO contaminated."

　　Another opposition group, ActionAid, has been organizing grass-roots support in Brazilian farming regions to rouse consumer sentiment against legalization. ActionAid public policy director Adriano Campolina says he is fighting for farmers to remain independent. "When the small-scale farmer or a big farmer starts using this kind of seed, this farmer will be completely dependent on the transnationals, which control intellectual property rights over these seeds," he said.

　　Brazilian scientist Crodowaldo Pavan said there should be checks on what multinationals can do, but that doesn't mean GM seeds should be banned. He says fears over their usage are unfounded. Despite the official ban, Dr. Pavan says up to one third of Brazil's soy crop is genetically modified, because GM seed is being smuggled from Argentina. Brazil's government has invested heavily in a GM project by the U.S. biotech company, Monsanto, but the project was put on ice following a successful court challenge by consumers.

　　The anti-GMO groups are hoping the politicians' preoccupation with the October presidential election will give them time to gather enough support to defeat any future attempts to legalize genetically altered crops.

　　答案及解析

　　41. 答案是[D] the legalization of genetically modified organisms

　　解析： 本文介紹的是巴西的一些民間組織如何反對轉基因作物。他們從轉基因產品對環境的汙染，對農戶身體的損害，以及對巴西經濟的影響出發，反對政府將轉基因作物合法化。文章主要介紹的是Non-governmental organizations ***NGOs***和ActionAid兩個組織。作者在文章末尾也介紹了一些其他的立場。例如巴西科學家Crodowaldo Pavan，他認為不能簡單地將轉基因作物一棍子打死。過分的擔憂是沒有必要的。政府即使禁止轉基因作物，也有從阿根廷走私過來的種子，這使得巴西三分之一的作物實際上都是轉基因的。巴西政府本來投資準備和美國的生化公司

　　Monsanto合作，但是因為消費者起訴並打贏了官司，該專案只能束之高閣。反對轉基因作物的組織還打算在10月的總統大選前對政客們施加壓力，準備將反對轉基因作物的鬥爭進行到底。 42. 答案是[B] second largest

　　解析：相關內容在文章開頭: Brazil is the world's second largest producer of soybeans behind the United States and ahead of Argentina. 巴西為世界上第二大大豆生產國。僅次於美國，位居阿根廷之前。

　　43. 答案是[B] They believe genetic engineering is altogether a bad practice.

　　解析：文章第二段介紹的是NGO的立場。作者引用NGO負責人Jean-Marc von der Weid 的話說，"We are not saying that genetic engineering is, in principle, something bad; we say that we need more science to be sure that it will work in an appropriate way with no harm in the future," said campaign coordinator Jean-Marc von der Weid. "This is both for health and environmental reasons. ***我們並不是說轉基因工程不好;我們的立場是，需要用科學方法來確保它不會在將來對環境造成危害。這主要是出於對環境和健康的考慮。***四個選項中只有[B]不符合NGO的立場。

　　44. 答案是[B] They encourage the farmers to depend on themselves for seeds.

　　解析：文章第三段介紹的是另一個反對組織，ActionAid。它也同樣反對降轉基因作物合法化。它號召巴西的農戶不要依靠跨國公司作為種子的來源，否則就會被牢牢地控制住，失去自主權。 45. 答案是[C] The fear over the use of genetically modified seeds is uncalled for.

　　解析：文章第四段有如下內容: Brazilian scientist Crodowaldo Pavan said there should be checks on what multinationals can do, but that doesn't mean GM seeds should be banned. He says fears over their usage are unfounded.巴西科學家Crodowaldo Pavan認為應該對跨國公司實行一定的監督, 但是不能對轉基因作物全盤否定。他說，擔心轉基因作物的危害，是沒有根據的***unfounded***。這和[C]的敘述相符合。
