Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic talked about by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life can be longer.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing with hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to make human beings in large quantities. In the past few years, scientists have succeeded in cloning babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
【小题1】What does “these two killers” in the second paragraph refer to?A．Gene technology and another treatment of the two diseases.B．The two murderers who killed the cloned baby.C．Hereditary disease and cancer.D．Cancer and heart disease.【小题2】In what way can gene technology help to treat hereditary diseases?A．Using gene technology, a scientist finds the wrong gene and corrects it.B．Using gene technology, people with hereditary diseases can live longer.C．Using gene technology, human babies can also be cloned.D．Doctors can cure cancer and heart disease with the help of gene technology.【小题3】What is the main purpose of writing the text?A．Explaining that gene technology will also do great harm to human race.B．Telling the readers the positive effects gene technology has on people’s life.C．Expressing the writer’s idea that gene technology will benefit people.D．Informing people that gene technology helps clone babies in large quantities.D

(答案→)D 解析：本文介绍了基因技术，详细讲述了基因技术对健康的好处【小题1】细节题：根据上文的such as cancer and heart disease.可知每年造成数百万人死亡的元凶就是癌症和心脏病，故选D。【小题2】细节题：根据第三段最后一句But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.可知基因技术被应用于治愈家族病。科学家可以找到错误的基因，纠正它，从而生出健康的孩子，故选A。【小题3】推断题：通读全文可知文章主要讲述了基因技术对人类的好处以及作者的观点。故选C。
