UNIT 9　HUMAN BIOLOGY
美 文 导 入
素养解读：《普通高中英语课程标准(2017年版)》要求对学生进行思维品质的培养。思维品质是思考辨析能力，包括分析、推理、判断、理性表达、用英语进行多元思维等活动。通过对克隆技术观点的展示，鼓励学生进行独立思考，培养批判性思维。主题：克隆学科素养：思维品质难度系数：★★★★
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.
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.

○重要短语

○句型精析
译文：这主要是因为我们对克隆的结果以及它可能对被克隆的人和世界其他地方产生的生理和心理影响还没有足够的了解。
