问题 共用题干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.______________(46)
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.
_____________(47)
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._____________ (48 ) 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.______________(49)
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._____________(50)Of course,the governments must take care to control
gene technology.
选项 _________（46）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 havebabies in very normal way.B:This means their children will for sure have the family disease.C:The scientists just need to find the wrong gene and correct it,and a healthy child will be born.E:In addition,the great amount of money people spend on curing their diseases can be saved,and it benefitst he economy as well.F:Clone technology is an achievement in science.
答案A
解析选项A中的these two disease、与空格前的cancer and heart discasc 相对应，因此A选项 符合题意。 联系上文，不难发现应填句于的内容应该与利用基因技术治疗疾病相关。纵览各选 项，选项E“另外的好处就是能够节省患者治病所需的大量的费用，有利于经济发展”与空前 所列基因技术治疗癌症和心脏病带来的好处正好接上。 第四段一开始就谈到基因技术能够帮助人们生出更加健康、聪明的孩子，接着开始了 hereditary disease。这一新话题，因此空格处的内客肯定与hereditary diseases 有关二通过分析剩 余选项，很容易就能友现选项D“这意味着他们的孩子一定会遗传家族疾病”与前后内存相 连贯。 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 关。C项说“科学家们只需要找到错误的基因并进行改正，一个健康的孩子就可以诞生了”，因 此正确答案为C。 本段空格前的内容是有些人对于利用基因技术克隆人类的担心，空格后作者建议政府 能够谨慎地控制基因技术。空格处所选答案应该能够起到承上启下的作用，B选项“而我认为 不会出现大量的克隆婴儿，因为世界上的多数夫妇能够以正常方式生出孩子"在结构和内容上 与上下文相连贯，表明了作者的观点，因此选B。第6部分：完形填空
