Question

Gene technology to benefit people

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

1.What does "these two killers" in the second paragraph refer to?

A.Gene technology and another treatment of the two diseases.

B.The two murderers who killed the cloned baby

C.The two diseases of cancer and heart disease

D.Hereditary diseases and cancer

2.What’s the main idea of the third paragraph?

A.How gene technology can be applied in the field of treating hereditary diseases.

B.Gene technology can be used to clone human babies.

C.Gene technology can help people to give birth of a baby.

D.Gene technology can help the English imperial family out

3.In what way gene technology can help to treat hereditary diseases?

A.Using gene technology, people with hereditary diseases can have more living days.

B.Using gene technology, scientist finds the wrong gene and corrects it.

C.Using gene technology, human babies can be cloned.

D.Doctors can cure cancer and heart disease with the help of gene technology.

4.What is the main purpose of writing this passage?

A.Expressing the writer’s idea that gene technology will benefit people

B.Telling people the advantages of gene technology

C.Telling the readers that gene technology will not benefit people

D.Explaining that gene technology will also do harm to the humanity

【解析】

本文是说明文。文章介绍了基因技术，详细讲述了基因技术的好处

1.词义猜测题。根据第划线词所在句前的The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease.（基因技术所能做的最伟大的事情就是治愈严重的疾病，而这些疾病是目前医生们几乎无能为力的，比如癌症和心脏病）及划线词所在句Every year, millions of people are murdered by these two killers.（每年都有数百万人被这两名杀手杀害）可知，每年造成数百万人死亡的元凶就是癌症和心脏病。由此可知，these two killers 指的是上文做的cancer and heart disease.故选C。

2.主旨大意题。根据第三段中的In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.（在过去，医生对遗传病无能为力。但是基因技术可以完美地解决这个问题。科学家只需要找到错误的基因并加以纠正，一个健康的孩子就会诞生）可知，第三段主要介绍了基因技术可以被应用于治愈家族病。故选A。

3.细节理解题。根据第三段最后一句The scientist just need to find the wrong gene and correct it, and a healthy child will be born（科学家只需要找到错误的基因和纠正它,和一个健康的孩子将出生）可知，利用基因技术，科学家发现错误的基因并加以纠正，这样就可以治愈家族病了。故选B。

4.推理判断题。根据文章标题Gene technology to benefit people（基因技术造福人类）及最后一段中的But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.（但我相信克隆婴儿不会大量出现，因为世界上大多数夫妇可以用非常正常的方式生育。当然，政府必须小心控制基因技术）可知，文章主要表达作者了认为基因技术将造福人类的观点。故选A。
