Question

    In 2006, documents were published by the United States Food and Drug Administration (FDA). They suggested that cloned animals and cloned animal products would be allowed into the American food supply.

The FDA has stated that cloned animal products are safe for consumption, and has performed many studies to support this view. In fact, products from cloned animals have already been eaten by some Americans without ill effects. The FDA analyzed the structure(结构)and content of cloned animal products and compared it with that of traditionally reproduced animals, and discovered no statistical difference between the two.

Consumers raised serious concerns about cloned animals. The first is the question of whether or not cloned tissue and animal products are truly safe. The second is that many clones are also genetically modified(转基因的)animals, which the FDA has said are unsafe for human consumption. The third is that consumers want to be able to choose what they put into their bodies.

The first concern about cloned animals is almost unnecessary due to the price of producing a clone. Making a clone needs hard work and is very costly. These clones live spoiled lives because they are very valuable, despite biologists' warning that cloned animals decrease diversity.

The second concern, about genetic modification of cloned animals, is more problematic. It may be very difficult to separate genetically modified animals from normal ones. The purpose of genetically modified cloned animals is unclear, and the FDA hasn't allowed their products onto the market, due to health concerns, but the risk of genetic pollution of healthy animals still exists.

Finally, the matter of choice is a large one. Many animal rights activists are worried about clone rights because cloned or not, the animals still have lives. Other consumers are simply trying to eat healthy foods, and have doubts about the cloned animals. If the FDA does not make labeling (贴标签)laws, people may not be able to make informed choices about their food.

1.Why did the FDA allow cloned animal products for consumption?

A.They appeal to consumers very much.

B.They differ from traditional animal products.

C.They taste better than normal animal products.

D.They have been proved safe in several aspects.

2.What do we know about producing clones of animals?

A.It takes much more efforts and money. B.It provides some new medical benefits.

C.It needs less time than raising animals. D.It helps increase the diversity of animals.

3.What can be inferred from the last paragraph?

A.Cloned animals should be forbidden to enter market.

B.Cloned animals should have the same rights as humans.

C.Laws should be made to protect people's right to choose food.

D.Animal rights activists are strongly against cloned animal products.

4.What's the text mainly about?

A.Doubts about cloned animals rights. B.Discussions about how to clone animals.

C.Concerns about animal cloning technology. D.Worries about cloned animal consumption.

【解析】

这是一篇说明文。文章主要说明了食用克隆动物的三个忧虑。

1.

细节理解题。根据第二段的内容，尤其是“The FDA has stated that cloned animal products are safe for consumption, and has performed many studies to support this view.”FDA已经声明克隆动物产品是安全的，并进行了许多研究来支持这一观点，可知，FDA认为克隆动物产品在很多方面被证明是安全的，所以允许食用克隆动物产品。故选D项。

2.

细节理解题。由第四段的第二句“Making a clone needs hard work and is very costly.”克隆动物需要艰苦的工作并且非常昂贵，可知，克隆动物花费了很多的努力和金钱。故选A项。

3.

推理判断题。由最后一段内容，尤其是“If the FDA does not make labeling (贴标签)laws, people may not be able to make informed choices about their food.”如果FDA不使用贴标签的法律,人们可能无法对他们的食物做出明智的选择。可以推断出，应该制定法律来保护人们选择食物的权利。故选C项。

4.

主旨大意题。这篇文章是总分结构，开头提出FDA建议允许克隆动物和克隆动物产品进入美国的食品供应。第三段提出了食用克隆动物的三个顾虑，第一，克隆组织和动物产品是否真正安全的问题；第二，许多克隆动物也是转基因动物，FDA表示是人类食用不安全；第三，消费者希望能够选择吃什么。第四、五、六段分别仔细论述了这三个忧虑。可以推断出这篇文章主要探讨了食用克隆动物的担心。故选D项。
