Andrew Carneigie, known as the King of Steel, built the steel industry in the United States, and, in the process, became one of the wealthiest men in America. His success resulted partly from his ability to sell the product and partly from his policy of expanding during periods of economic decline, when most of his competitors were reducing their investments. Carnegie believed that individuals should progress through hard work, but he also felt strongly that the wealthy should use their fortunes for the benefit of society. He opposed charity, preferring instead to provide educational opportunities that would allow others to help themselves. "He who dies rich, dies disgraced", he often said. Among his more noteworthy contributions to society are those that bear his name, including the Carnegie Institute of Pittsburgh, which has a library, a museum of fine arts, and a museum of national history. He also founded a school of technology that is now part of Carnegie-Mellon University. Other philanthropic gifts are the Carnegie Endowment for International Peace to promote understanding between nations, the Carnegie Institute of Washington to fund scientific research, and Carnegie Hall to provide a center for the arts. _ . His contributions of more than five million dollars established 2,500 libraries in small communities throughout the country and formed the nucleus of the public library system that we all enjoy today.

Q: Eat,drink and be merry. That's what Spring Festival is all about. But there are millions of people,too,who love to let happiness go up in smoke. Offering cigarettes to guests is a traditional Chinese way of showing respect for them. A cup of tea and cigarettes are perhaps the most common way of welcoming a guest in China,especially during festive occasions. No wonder,40 percent of the people surveyed recently said they would smoke at least twice the usual number of cigarettes during the Spring Festival because of all those gatherings and parties. Only 20 percent of the respondents said they would refuse a cigarette when offered one. Why can't the others do the same?Because they could be seen as being rude,said more than half of the respondents. Fifteen percent feared they could be taken as "someone who cannot get along well with others". The Think tank Research Center for Health Development and sohu.com survey shows 61 percent Chinese think offering a cigarette is useful for socializing,and 52 percent have offered cigarettes to others. The study surveyed 3,800 people,64 percent of them men. One third of those surveyed were smokers,out of which 57 percent said they couldn't give up smoking because of the offering and accepting culture. "People have accepted offering cigarettes as an effective way of making friends," research center director Wu Yiqun says. China has more than 350 million smokers,catering to the tobacco market that is worth 500 billion yuan. "The survey shows we still have a lot of work to do," Wu says. "Since Beijing is trying to make the Olympic Games smoke free,it is time to let people know that offering a cigarette is a bad habit and it should be given up immediately."

Q: Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too. " The result of the experiment shows that _ plays an important role in the infection of colds. A) sneezing at the infected person B) touching the infected person C) sitting together with the infected person D) talking with the infected person
