题目内容
10.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's 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(皇帝的)family being a good example,have hereditary(遗传的)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.Scientists 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(生产)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 governments must take care to control gene technology.
60.What does"these two killers"in the second paragraph refer to?C
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.
61.What's the main idea of the third paragraph?C
A.Gene technology can help people to give birth to a baby.
B.Gene technology can be used to clone human babies.
C.How gene technology can be used to treat hereditary diseases.
D.Gene technology can solve all the problems of the English imperial family.
62.In what way can gene technology help to treat hereditary diseases?B
A.Gene technology helps people with hereditary diseases to live longer.
B.Using gene technology,scientists find the wrong gene and correct it.
C.Using gene technology,human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
63.What is the main purpose of writing this passage?A
A.Expressing the writer's idea that gene technology will benefit people.
B.Telling people the advantages and 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.
分析 本文为科教类说明文,文章介绍了基因两大好处:治疗目前医生束手无策的严重的疾病如癌症和心脏病; 找出家族基因中的问题基因并纠正,生出健康的宝宝;有人担心基因技术会导致大量的基因宝宝的出现,但是作者认为这种现象不会有,因为大多数人都能够以正常的方式生孩子;但是政府还是要小心控制基因技术.
解答 60.答案是C.细节理解题.上文例举了两种严重的医生束手无策的疾病"such as cancer and heart disease",紧接着下文就题到了"Every year,millions of people are murdered by these two killers.(每年这两大杀手谋杀了上百万的人们)",由此推断两大杀手指的是cancer和heart disease,故选C.
61.答案是C.段落大意题.文章首句"Gene technology can help people to give birth to more healthy and clever children.帮助人们生育健康聪明的孩子"为该段的主题句,下文展开说明如何克服家族遗传,生出健康的孩子;故选C.
62.答案是B.细节理解题;根据第三段中".Scientists just need to find the wrong gene and correct it,and a healthy child will be born.(找到问题基因并纠正,这样就能生出健康的孩子),故选B."
63.答案是A.主旨大意题;读全文可知文章主要讲述了基因技术对人类的好处并对存在的担忧进行说明,故选A.
点评 本文介绍了基因技术的好处,同时对人们的担忧进行解释.抓住每一段的要点可以有助于整体理解文章.文章主语考查细节题和主旨大意题,在做细节题时根据题干定位细节,在语境中正确理解原句,然后对照选项做出合理的判断.对于主旨大意的判断要把握文章整体,避免以偏概全.
