听力原文:Italian scientists have raised new health concerns about the safety of using mobile phones, with research showing radio waves from the handsets makes cancerous cells grow more aggressively. When Fiorenzo Marinelli and his colleagues at the National Research Council in Bologna exposed leukemia cells in the laboratory to 48 hours of continuous radio waves they initially killed the cancer cells but then made the surviving tumor cells replicate more rapidly.
We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively.
The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors.
The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively.
What is the speaker's main topic?
A.Effects of using mobile phones on healthy human cells.
B.Risks of developing cancer involved in the use of mobile phones.
C.Damage to healthy cells caused by the use of mobile phones.
D.The potential health hazards of mobile phones on humans.

Kaleil Isaza Tuzman moved to the United States from Columbia when he was 15.Within a few years he was pushing to get ahead, hawking (叫卖) baseball caps to pay the bills his Harvard scholarship didn't cover.
After graduating, he landed on Wall Street, but every night he dreamed of working for himself.During the booming (繁荣的) 1990s, he gave it a try when he and a partner started govWorks - a software company that helped city government go online.
They raised $60 million and expanded like crazy.Then dotcoms started turning into dotbombs - govWorks broke up too.Says Isaza Tuzman, "Entrepreneurs (创业人) have to be ready for both success and failure.In Columbia if you fail, you become a pariah and no one will do business with you.The wonderful thing about this country is you can get up again."
From national parks to moon landings, America has given the world some amazing ideas.But the American Dream is still the biggest - the idea that with hard work and a bit of luck you can be whoever you want to be.Historian James Truslow Adams once wrote that Americans believe "life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement."
These days there's pressure on the dream idea.A 1978 study of boys born and raised after World War II found an astonishing 23% of the poorest had reached the top of the income heap by 1973.Now, in a typical generation, only 10% work their way from bottom to top.
But every day, some still do make it.After govWorks went bankrupt, Isaza Tuzman built on what he had learned.His new company, Recognition Group, restructures (重组) firms and finds them venture capital?–?nearly $150 million so far.Last year, "Hispanic Business" magazine named him to its 100 Most Influential list.Not bad for a dreamer, in a country built on dreams.
41.What did Kaleil Isaza Tuzman dream of after graduating from college______

B.More and more people are feeling the pressure to work harder in order to realize their dreams.
C.It is becoming more and more unpopular because few people today can move up the social ladder.
D.If one works hard enough, he will eventually make his dreams come true.
