人教版高中英语选修八unit2 Cloning
unit2 CloningⅠ.阅读理解AThere are many ways in which human cloning is expected to benefit humans.Dr Richard Seed, one of the leading supporters of humancloning technology, suggests that it may someday be possible tocompletely change the aging process because of what we learn fromcloning.Scientists believe that they may be able to treat heart attackvictims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the US and several other industrialised countries.There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer’s disease, Parkinson’s disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.Though current treatments for infertility (不生育) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.语篇解读：本文作者从几个方面介绍了克隆人技术给人类带来了利益。
