What Can GeneTechnology Bring

Among all the fastgrowing science and technology,the research of human genes,or biologicalengineering

as people call it,isdrawing more and more attention now,Sometimes it is a hot topic discussed bypeople.

The greatest thingthat gene technology can do is to cure some serious diseases.Doctors at presentcan

Gene technology canhelp people to give birth to more healthy and clever children.Somefamilies,with

the English imperialfamily being a good example , have hereditary（遗传的）diseases._____________ (48 ) This

is a great troublefor these families.In the past,doctors could do nothing about the hereditarydiseases.But

gene technology cansolve this problem perfectly.______________(49)

Some people areworrying that the gene research can be used to manufacture human beings inlarge

quantities.In thepast few years,scientists have succeeded in cloning a sheep,so these peoplepredict that

human babies wouldsoon be cloned._____________(50)Of course,the governments must take care tocontrol

gene technology._________（46）

A.Everyyear,millions of people are murdered by these two diseases.

B.But I believecloned babies will not come out in large quantities,for most couples in theworld can havebabies in very normal way.

C.This means theirchildren will for sure have the family disease.

D.The scientistsjust need to find the wrong gene and correct it,and a healthy child will beborn.

E.In addition,thegreat amount of money people spend on curing their diseases can be saved,and itbenefitst he economy as well.
