For some, its a welcome development designed to make our lives easier. For others, it represents a threat to the health and balance of society, especially from a moral perspective. Looking at these cloning pros and cons, its important to consider the scientific, financial, and social aspects of cloning processes. From a scientific perspective, cloning can be considered major progress. Scientists arent limited by population. Its also possible to clone pieces of living things. However, cloning changes the natural order of life and death. Why should scientists have to treat an animal well in the lab if they can just make more? As a result, scientists may become lazy or careless with the living things they work on. Cloning is a major business. Medical research groups have invested millions of dollars in making cloning possible. As a result, they can make big profits from selling cloning services to hospitals and the public. However, the wealth they achieve doesnt mean that cloning itself is a profitable trial. For example, while a company may clone an organ, its price may be too high to afford. As a result, only rich people and governments could use cloning products. As a whole, cloning for society can be debated for hours. On one hand, you have religious groups, who say that cloning is wrong. On the other hand, you have many people who are looking forward to making clones of themselves so that the clone can serve as a worker and leave the original person to enjoy a life of relaxation and wealth. 【解題導(dǎo)語(yǔ)】人們對(duì)克隆問(wèn)題意見(jiàn)不統(tǒng)一, 有人贊成, 也有人反對(duì)。但作者認(rèn)為應(yīng)該全面思考克隆的問(wèn)題。1We can conclude from the first paragraph that _.

CPatients have to buy cloning products from hospitals or governments. DScientists may pay attention to quantity of cloning products rather than quality. 解析:選B推理判斷題。從第四段中的“As a result, only rich people and governments could use cloning products. ”可知, 因?yàn)榭寺〕杀靖撸?克隆產(chǎn)品投放到市場(chǎng)后, 并不是所有人都買得起, 只有有錢人和政府能夠支付得起。BScience 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(倫理的) 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 (并發(fā)癥) resulting from malformed(畸形) organs. There are also serious ethical issues in danger. In essence(在本質(zhì)上), those who are against cloning would argue that scientists have no right to play God and to interfere(干擾)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. 【解題導(dǎo)語(yǔ)】這篇文章主要講了作者對(duì)于克隆的觀點(diǎn)。作者認(rèn)為如果在可控范圍內(nèi), 克隆對(duì)研究治愈疾病是非常有幫助的。作者認(rèn)為如果干細(xì)胞研究對(duì)人類的生活無(wú)害,政府應(yīng)該繼續(xù)支持。 4What is the writers 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. 解析:選C細(xì)節(jié)理解題。根據(jù)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,作者對(duì)于克隆的觀點(diǎn)是, 如果在可控范圍內(nèi), 它對(duì)研究治愈疾病是非常有幫助的。5.
