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.

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

答案与解析

本文介绍了阿拉伯联合酋长国某一地区突发的禽流感案例以及相关组织采取的措施。

1．as 考查介词。be known as...是固定结构，表示“作为……而出名”。

2．highly 考查副词。修饰形容词 deadly，表示“非常；高度地”，应用 highly。

3．to have infected 考查非谓语动词。“Sb./Sth. is/was reported to v”是固定句式，该句中动词 infect 发生在 was reported 之前，且与主语是主动关系，故用 to have infected。

4．has been reported 考查时态语态。此处 report 是 sporadic infection 的谓语动词，两者是被动关系，且表示到目前为止发生的动作，故用现在完成时的被动语态，且主语是 sporadic infection，故填 has been reported。

Dear Tom，

I am glad to hear that you are going to Canada to study. So I was writing to tell you anything about this country.

Locating in North America, Canada is the second large country with the largest number of lakes in the world. The majority of people lives in the center of the country. However, I suggest that you chose to study in the east, because there are many international students here and the tuition is lower. During your study, you can take the part in more activities after class, where you can make more friends from different country. In this way, your life will rich and colorful.

Hope you will have a wonderful life there.

Yours，

Li Ming
