John H. Johnson was born in a black family in Arkansas city in 1918. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
　 Fortunately he had a strong-willed (意志坚强的) caring mother. John remembered that his mother told him many times, “Son, you can be anything you want really to be if you just believe.”She told him not to depend on others, including his mother. “You have to earn success, ”she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
　 These words came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15, to Chicago.
　 Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words—as an editor of the newspaper and yearbook at Du Sable High School. His wish was to publish a magazine for blacks.
　 While others discouraged him, John’s mother offered him more words to live by. “Nothing beats a failure but a try. ”She also let him pawn(典当)her furniture to get the $ 500 he needed to start the Negro magazine.
　 It is natural that difficulties and failures followed John closely until he became very successful. He always keeps his mother’s words in mind.“Son, failure is not in your vocabulary!”
　 Now John H. Johnson is one of the 400 richest people in America—worth $ 150 million.

　　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.

(2) What's Li Ning's purpose to take driving cars for example?

[　　]
