Among all the fast growing science and technology, the research of human genes（基因）, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed 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（应用）, not only these two diseases can 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 span(寿命) can be prolonged.
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 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 about 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 manufacture (produce) human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned 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 babyC．The two diseases of cancer and heart diseaseD．Hereditary diseases and cancer【小题2】What’s the main idea of the third paragraph?A．How gene technology can be applied to cure family diseases.B．Gene technology can be used to clone human babies.C．Gene technology can help people to give birth to a baby.D．Gene technology can help the English imperial family out【小题3】What is the main purpose of writing this passage?A．Expressing the writer’s idea that gene technology will benefit peopleB．Telling people the advantages of gene technologyC．Telling the readers that gene technology will not benefit peopleD．Explaining that gene technology will also do harm to the humanity【小题4】Which of the following worries people by using this technology?A．Scientists have already successfully cloned sheep.B．Most couple will normally give birth to babies.C．A good number of babies will be clonedD．The government will take action to control it.C

(答案→)C 解析：文章是关于基因技术，详细讲述了基因技术的好处。【小题1】推理题。根据上文的such as cancer and heart disease.【小题2】主旨大义题。通读第三段，第三段是关于基因被应用于治愈家族病。【小题3】主旨大义题。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。【小题4】细节题。根据文章最后一段Some people are worrying that the gene research can be used to manufacture (produce) human beings in large quantities.

我明天再问问老师，叫他解释下这个问题
