Clone Technology Like Driving Cars
The recent death of the world's most famous sheep--Dolly the clone--has not dampened（使沮丧）the enthusiasm（热情）of Chinese scientists, who are working hard to make more breakthroughs（突破）in clone technology.
“It is hard to say whether Dolly died at a relatively young age or died from defects（缺陷）in reproduction.”Du Miao, a researcher with the Biology and Growth Institute of the Chinese Academy of Sciences, told China Daily in Beijing yesterday.“But Dolly's case reminds us that both Chinese and foreign scientists should put more efforts into improving clone technology as well as disease treatment techniques in the field of cloning animals.” He said his institute, in co operation（合作）with Yangzhou University in Eastern China's Jiangsu Province, had cloned more than 10 sheep since 1999 and the oldest is nearly five. They are all still alive.
Li Ning, deputy（代表）director of the National Key Laboratory of Agricultural and Biological Technology, who is also a professor with the Beijing Based China Agriculture University, said, “Clone technology is actually progressing well. Dolly is the first cloned sheep after all. Like driving cars, new drivers meet with accidents more easily, but the more you drive, the easier and safer you feel. In the future, the death rate of cloned animals will be reduced with technological developments.”
“Official reports show seven locally cloned sheep are still alive. Clone technology in China is gradually approaching（接近）a level of commercialization（商业化）,”Li added. But Wang Yu, deputy（代表）director of the Biological Technology Centre under the Ministry of Science and Technology, said the commercialization of clone technology depends on market demand.
(1) Which of the following statements is ture?
[ ]
A．Some Chinese scientists believe Dolly died from defects in reproduction.
B．Some Chinese scientists think Dolly's death has dampened their enthusiasm.
C．Some Chinese scientists are satisfied with their successes in clone.
D．Some Chinese scientists think they should improve not only disease treatment techniques but also clone technology.
(2) What's Li Ning's purpose to take driving cars for example?
[ ]
A．To tell the people clone technology was too difficulty in the past.
B．To show clone technology is difficult in the beginning and has a bright future.
C．To show clone technology will be more difficult in the future.
D．To tell people Chinese scientists met too much difficulty in the beginning.
(3) From the passage, we can know _____.
[ ]
A．the Chinese clone technology is behind some other countries
B．the Chinese scientists learn lessons from Dolly
C．the Chinese clone technology is Well Developed
D．the Chinese clone technology is actually developing well

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 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, 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(皇室) 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 about hereditary diseases. But gene technology can solve this problem perfectly. The scientist 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 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.
