Question

Science and technology have advanced at such a rate that cloning has now become a reality. The possibility of cloning humans is a serious issue(争论点) and raises ethical(伦理的) questions. In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments.

Research into cloning and stem(严格的) cell production is primarily aimed at finding new treatments for currently incurable illnesses. While this would improve the quality of life for many, not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. Furthermore, it is thought that a cloned human would be unlikely to survive birth and would suffer from complications(并发症) resulting from malformed(畸形) organs .

There are also serious ethical issues in danger. In essence(在本质上), those who are against cloning would argue that scientists have no right to play God and to interfere(干扰)with natural processes. Producing embryos for the purpose of harvesting stem cells for research presents important questions about the nature and status of the embryo being produced. It may also make us question whether throwing it away after use reduces the value we place on human life.

In conclusion, I do not agree that research into cloning using human embryos should continue. This is not only because it may reduce the value we place on human life, but also because not enough is known about the effects.   However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it.

1.What is the writer’s general opinion on cloning?

A. It is useful in every area of research.

B. It needs to be carefully controlled by governments.

C. It is useful for research into cures for disease if it is controlled.

D. It is only useful for research into cures for disease.

2.The underlined word “approach” in the first paragraph means “______”

A. reach a high level or amount    B. move forward

C. come near    D. deal with

3.The writer’s main reason against cloning is that ______.

A. not enough is known about the effects of cloning

B. a cloned human would be likely to die of malformed organs

C. cloning has negative physical and psychological effects on clones

D. it would affect the quality of life for many

4.In the last paragraph, the writer thinks governments should______

A. not put human life at risk

B. support all forms of research into stern cell production

C. not support any form of research into stern cell production

D. support research into stern cell production harmless to humans life

Answer

1.C

2.C

3.A

4.D

【解析】这篇文章主要讲了作者对于克隆的观点。作者认为如果在可控范围内，克隆对研究治愈疾病是非常有帮助的。作者认为政府应该继续支持干细胞研究，如果它对人类的生活无害。

1.根据In my opinion, cloning is useful for research into cures for disease. However, I think that it needs to be approached with caution and carefully monitored by governments. 可知作者对于克隆的观点是，如果在可控范围内，它对研究治愈疾病是非常有帮助的。

2.根据In my opinion, cloning is useful for research into cures for disease. 可是这里意思是如果小心谨慎和被政府监控，克隆技术需要被接近，可猜出“approach” 意思是接近靠近。

3.根据not enough is understood about what effects cloning would have on the world in the future. This is primarily because we do not understand enough about the results of cloning and both the physical and psychological effects that it is likely to have on cloned humans and on the rest of the world. 可知作者反对克隆的主要原因是因为对于克隆的影响，人们了解的不足够多。

4.根据However, I do think that if there is a way to produce stem cells using cloning which does not put human life at risk, then governments should continue to support it. 可知根据最后一个自然段来看，作者认为政府应该继续支持干细胞研究，如果它对人类的生活无害。
