Ever since the world was introduced to Dolly，the cloned sheep，in 1997，various fears have been expressed that researchers would be tempted to apply to humans the techniques that were used to produce her.Some objections have been practical; many scientists have warned that these techniques remain too dangerous.Others have focused on the unpredictable psychosocial consequences of producing humans that are genetically identical to other individuals.But the strongest opposition has been based on a moral certainty that，whatever the practical risks involved，producing carbon copies of human beings is ethically unacceptable.
The United Nations faces an opportunity to turn this moral certainty into international law when a committee takes up discussion of a possible treaty that would make what is known as “reproductive cloning” a criminal offence.Building on a long line of international treaties targeting unethical practices，from human slavery to the use of biological weapons，the United Nations is likely to be asked to approve a new agreement that would place human cloning in the same category.
In this case，however，the United Nations is in danger of shooting itself in the foot.For the debate over the outlawing of reproductive cloning has been hijacked by those whose principal goal is different.To achieve this，they are seeking to have the proposed ban extended to cover not only the reproductive cloning of human beings，but socalled “therapeutic cloning” as well.This involves growing fertilised embryos for several days，and then extracting from them cells that might later be used as replacement tissue or organs for other individuals.
Notes：
①ethically adv.伦理上 ②unethical adj.不道德的
③therapeutic adj.治疗的 ④hijack vt.劫持
长短句分析：Ever since the world was introduced to Dolly，the cloned sheep，in 1997，various fears have been expressed that researchers would be tempted to apply to humans the techniques that were used to produce her.
句法点睛：本句中，since引导时间状语从句，第一个that引导同位语从句，修饰fears;第二个that引导定语从句，修饰techniques。
句意：自从1997年世界上第一次有了多利羊，人们表示出了各种担心，担心研究者会受诱惑把克隆羊的技术用到人类身上。
【语篇解读】 克隆羊多利出现以后，人们担心研究者会被利益驱动去克隆人。一个委员会想敦促联合国就再生性克隆提出法律上的限制，但是这里面也出现了麻烦。如果这条法律通过了，医疗克隆也就被禁止了。
1.What was the fear of people after Dolly，the cloned sheep?
A.They feared that the sheep would die soon.
B.Techniques to clone animals were dangerous.
C.Researchers would clone human beings.
D.Researchers would produce therapeutic cloning.
答案 C [细节理解题。从“various fears have been expressed that researchers would be tempted to apply to humans the techniques that were used to produce her”我们知道，克隆羊出现后，人们的担心是，研究者会被利益驱动着去克隆人。]
2.What does the underlined word “identical” in the first paragraph mean?
A.Different. B.Similar in looks.
C.Special. D.Harmful.
答案 B [词义猜测题。联系后面的“to other individuals”，再结合克隆的特点可知，他们担心克隆出来的人与其他人在外观上是一样的。]
3.What's the committee's treaty about cloning?
A.Any activity of cloning humans is a criminal offence.
B.Reproductive cloning would be a criminal offence.
C.Cloning should be banned now.
D.The use of biological weapons is allowed.
答案 B [细节理解题。从“a committee takes up discussion of a possible treaty that would make what is known as ‘reproductive cloning’a criminal offence”可以知道，委员会在讨论关于再生性克隆是违法的条约。]
4.If there is a treaty to ban reproductive cloning ________.
A.it is likely to clone humans at present
B.cloning will bring unethical problems
C.it is still a problem how we make scientific research by cloning
D.therapeutic cloning will also be banned
答案 D [细节理解题。从“To achieve this，they are seeking to have the proposed ban extended to cover not only the reproductive cloning of human beings，but socalled‘therapeutic cloning’as well.”可知，如果这个条约实施，不仅克隆人是犯罪，连医疗克隆也是犯罪。]
