What Can Gene Technology Bring
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 some serious diseases. Doctors at present can almost do nothing with them. Cancer and heart disease are the examples.1.______
And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, these two diseases can be cured completely, bringing happiness and more living days to the patients.2______
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary（遗传的）diseases.
3______ This is a great trouble for these families. In the past, doctors could do nothing about the hereditary diseases. But gene technology can solve this problem perfectly.4______
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, so these people predict that human babies would soon be cloned. 5______ Of course, the governments must take care to control gene technology.
4.
A、Every year, millions of people are murdered by these two diseases.
B、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.
C、The scientists just need to find the wrong gene and correct it, and a healthy child will be bom.
D、This means their children will for sure have the family disease.
E、In addition, the great amount of money people spend on curing their diseases can be saved, and it benefits the economy as well.
F、Clone technology is an achievement in science.
【正确答案】：C
【题目解析】：空格前的内容主要讲述过去，医生对家族遗传疾病无能为力，但是基因技术能够完美地解决这一难题，因此空格应填句子的内容应该与基因技术如何解决家族遗传疾病这一信息相一致。剩余选项中只有选项C“科学家们只需要找到错误的基因进行改正，就可以生出健康的孩子”，而且与“Gene technology can help people to give birth to more healthy and clever children”的中心意思一致，因此正确答案为C项。
