Question

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(壽命) can be prolonged. www.zxxk.com

Gene technology can help people to give birth to healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遺傳的) 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 government 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 to 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, the 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 disadvantages 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.

試題分析：本文介紹了基因技術(shù)，詳細講述了基因技術(shù)的好處

1.細節(jié)題：根據(jù)上文的such as cancer and heart disease.可知每年造成數(shù)百萬人死亡的元兇就是癌癥和心臟病，故選C。

2.推斷題：通讀第三段，第三段是關(guān)于基因被應(yīng)用于治愈家族病。故選A。

3.細節(jié)題：根據(jù)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”科學(xué)家只需要找到錯誤的基因和糾正它,和一個健康的孩子將出生，故選B。

4.推斷題：通讀全文可知文章主要講述了基因技術(shù)對人類的好處以及作者的觀點。故選A。
