Question

【題目】Directions: Complete the following passage by using the sentences in the box. Each sentence can only be used once. Note that there are two sentences more than you need.

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. 【1】.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing about, such as cancer and heart disease. 【2】. And to date, doctors have not found an effective way to cure them. But if gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to patients, but the great amount of money people spend on treating their diseases can also be saved, therefore it benefits the economy as well. In addition, human life spans (壽命) can be prolonged.

【3】. 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. The scientist just needs to find the wrong gene and correct it, and a healthy child will be born.

【4】. 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 a very normal way. Of course, the government must take care to regulate gene technology.

A.Every year, millions of people are murdered by these two killers.

B.Gene technology can help people to give birth to healthy and clever children.

C.Doctors can cure cancer and heart disease with the help of gene technlogy.

D.Many people, however, are worried that gene technology can be used to manufacture human beings in large quantities.

E.Sometimes it is a hot topic discussed by people.

F.Using gene technology, people with heredity diseases can have more living days.
