A

(山东滨州模拟)

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 and raises ethical (伦理的) problems. 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 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.

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。作者认为如果它对人类的生活无害,政府应该继续支持干细胞研究。

1What is the writer's general opinion on cloning?

AIt is useful in every area of research.

BIt needs to be carefully controlled by governments.

CIt is useful for research into cures for disease if it is controlled.

DIt is only useful for research into cures for disease.

答案:C

解析:细节理解题。根据第一段中的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。

2The underlined word “approached” in the first paragraph means “________”

Areached a high level or amount

Bmoved forward

Ccome near

Ddealt with

答案:D

解析:词义猜测题。根据第一段可知作者认为克隆人的问题需要小心谨慎处理,对待,可猜出“approach”意思是处理,对待

3The writer's main reason against cloning is that ________.

Anot enough is known about the effects of cloning

Ba cloned human would be likely to die of malformed organs

Ccloning has negative physical and psychological effects on clones

Dit would affect the quality of life for many

答案:A

解析:推理判断题。根据第二段中的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可知作者反对克隆是因为对于克隆的影响,人们了解得不够多。

4In the last paragraph, the writer thinks governments should

________.

Anot put human life at risk

Bsupport all forms of research into stem cell production

Cnot support any form of research into stem cell production

Dsupport research into stem cell production harmless to human life

答案:D

解析:细节理解题。根据最后一段中的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.可知作者认为如果它对人类的生活无害,政府应该继续支持干细胞研究。
