Question

【题目】Are GM（转基因的) foods safe for people? Can they help solve the poverty problem? They have been the subjects of a hot debate.

This debate is related to increasing challenges from rising climatic change, population growth, urbanization（城镇化), and natural resource consumption. According to the Food and Agriculture Organization, food production needs to increase by 60 percent by 2050 in order to feed 9 billion people. Scientists and policymakers are searching for effective ways to gain nutritious food, for today and future. Unlike previous agricultural methods (such as the Green Revolution), GM crops are to fight food safety and poverty challenges.

The great expansion of GM crop varieties over the last two decades can be seen easily. The total area devoted to GM crops has increased 100 times from 1.7 million hectares in 1996 to 170 million hectares in 2012. Developing countries now grow more GM crops than developed countries (in terms of area), largely driven by Brazil’s rapid adoption of GM crops. China is home to about 4 percent of the total global area devoted to GM crops. Beans, corn, and cotton are main global GM crops, while China’s focus is on cotton, papaya, and poplar.

Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU, “the main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 research groups, is that biology methods, are not more risky than traditional planting technologies, for example.” Other international and national scientific bodies, such as the World Health Organization, have reached the same conclusion.

Answer 1

【答案】

【1】B

【2】C

【3】D

【4】B

【5】A

【解析】

试题分析:为了解决世界粮食问题，科学家研制出了转基因食品，很多人担心这种食品的安全性，事实证明，转基因食品是安全的。

【1】B事实细节题。根据短文GM crops are to fight food safety and poverty challenges.可知转基因食物最主要是用来解决人口增长所带来的粮食问题，故选B。

【2】C事实细节题。根据第一段Are GM（转基因的) foods safe for people? 可知人们最多关注的是转基因食品的安全问题，故选C。

【3】D事实细节题。根据短文The great expansion of GM crop varieties over the last two decades can be seen easily. 可知第三段主要讲的是转基因食品种类的增多，故选D。

【4】B推理判断题。根据短文Recently, a scientific study shows that GM crops are safe for people and the environment可知这个调查研究主要是想告诉人们转基因食品对人类和环境都是安全的，故选B。

【5】A推理判断题。根据最后一段Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU可知作者举这个调查的例子就是想证明转基因食品的安全性，同时表达自己支持转基因食品的态度，故选A。
