What Can Gene Technology Bring
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 discussed by people.
The greatest thing that gene technology can do is to cure some serious diseases. Doctors at present can almost do nothing with them. Cancer and heart disease are the examples.1.______
And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, these two diseases can be cured completely, bringing happiness and more living days to the patients.2______
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.
3______ This is a great trouble for these families. In the past, doctors could do nothing about the hereditary diseases. But gene technology can solve this problem perfectly.4______
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, so these people predict that human babies would soon be cloned. 5______ Of course, the governments must take care to control gene technology.
