Question

【題目】Are GM（轉(zhuǎn)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（城鎮(zhèn)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.

【1】 Nowadays, people are developing GM foods mainly to fight against______.

A. urbanization

B. population growth

C. rising climatic change

D. natural resource consumption

A. traditional planting technologies are more risky

B. the safety of GM crops has been proved in many ways

C. the safety of GM crops was reported by the EU in 2010

【5】 What’s the writer’s attitude towards GM crops?

A. Supportive. B. Opposed.

C. Unknown. D. Indifferent.

Answer 1

【答案】

【1】B

【2】C

【3】D

【4】B

【5】A

【解析】

試題分析:為了解決世界糧食問題，科學家研制出了轉(zhuǎn)基因食品，很多人擔心這種食品的安全性，事實證明，轉(zhuǎn)基因食品是安全的。

【1】B事實細節(jié)題。根據(jù)短文GM crops are to fight food safety and poverty challenges.可知轉(zhuǎn)基因食物最主要是用來解決人口增長所帶來的糧食問題，故選B。

【2】C事實細節(jié)題。根據(jù)第一段Are GM（轉(zhuǎn)基因的) foods safe for people? 可知人們最多關(guān)注的是轉(zhuǎn)基因食品的安全問題，故選C。

【3】D事實細節(jié)題。根據(jù)短文The great expansion of GM crop varieties over the last two decades can be seen easily. 可知第三段主要講的是轉(zhuǎn)基因食品種類的增多，故選D。

【4】B推理判斷題。根據(jù)短文Recently, a scientific study shows that GM crops are safe for people and the environment可知這個調(diào)查研究主要是想告訴人們轉(zhuǎn)基因食品對人類和環(huán)境都是安全的，故選B。

【5】A推理判斷題。根據(jù)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可知作者舉這個調(diào)查的例子就是想證明轉(zhuǎn)基因食品的安全性，同時表達自己支持轉(zhuǎn)基因食品的態(tài)度，故選A。
