Unit 2 Cloning

Ⅰ.阅读理解

(2017·阳高县一中月考)

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 (皇家的) family being a good example, have hereditary 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 a very normal way. Of course, the governments must take care to control gene technology.

1．What does “them” in the second paragraph refer to? A．People with cancer or heart disease. B．Millions of people with serious diseases. C．Some diseases doctors can do nothing with. D．The two illnesses of cancer and heart disease.

2．What can gene technology do according to paragraph three? A．It can help the English imperial family out.

1

B．It can be used to clone human babies. C．It can help people to give birth of a baby. D．It is likely to treat hereditary diseases.

3．What are people worried about according to the passage? A．Human babies may be cloned in a large scale. B．Healthy human babies will soon be cloned. C．Scientists may well find the wrong genes. D．The government may not control gene techs. 4．This passage is mainly written to ________. A．show gene technology will benefit people B．show gene technology will do harm as well C．tell that gene technology is a hot topic D．tell that gene technology is growing fast
