     A new study has found no evidence that sunscreen, commonly used to reduce the
risk of skin cancer, actually increases the risk.
     Researchers from the Umversity of Iowa based their findings on a revicw of 18 earlier
studies that looked at the association between sunscreen use and melanoma(黑素瘤 ).
They said that they found flaws in studies that had reported associations between sunscreen
use and higher risk of melanoma.
     Most health experts believe that by protecting the skin from the harmful effects of
the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (發(fā)生率)
faster than any other cancer in the United States.
     But questions have been raised about sunscreen and whether it may have the opposite
effect, perhaps by allowing people to remain exposed to the sun longer without burning.
     The researchers said that among the problems with some earlier studies is that they
often failed to take into account that those people most at risk for skin cancer-people
with fair skin and freckles(雀斑) ,for example-are more likely to use sunscreen. As a
result , it may appear that sunscreen users get cancer more often.
     The studies , which generally relied on volunteers to recall their sunscreen use,were
also unable to prove how well the products had been applied , Said the new study.

1. Theunderlinedword" flaws "inthe2ndparagraphmost probably means ________.
A. evidences
B. facts
C. faults
D. failures
2. People with fair skin and freckles ________.
A. seldom use sunscreen
B. are more in danger of skin cancer
C. can be free from the harm of the sun
D. often expose themselves to the sun
3. We can learn from the passage that _______.
A. sunscreen users get skin cancer more often
B. the volunteers have proved the effect of sunscreen
C. the new study was based on the experiences of volunteers
D. the number of skin cancer patients is increasing in America
4. Which of the following can be the best title for this passage?
A. Sunscreen to Prevent Skin Cancer
B. Sunscreen to Increase Skin Cancer
C. Skin Cancer Caused by Sunscreen
D. Skin Cancer Caused by Freckles

    As a teenager in 1972, Bill Gates boasted that he would be a millionaire by the time he was 20. While he did not quite achieve that goal, only 15 years later, he was a millionaire. And by 1992, as head of the Microsoft company, he became the richest man in America with assets (資產(chǎn)) of approximately US $ 6. 3 billion.

        Born in Seattle, Washington on 28, October, 1956, Gates was named William Henry after his father and grandfather. From the beginning, he was an extremely energetic and intelligent child. He had read the entire world book encyclopedia (百科全書(shū)) by the age of nine. His favorite subjects at school were science and math and his favorite pastime was “thinking”.

        Gates first started to play with computers at the age of 13, when one was installed at his school. At that time, computers were large, awkward (笨重的) machines. Operators were required to learn complex (復(fù)雜的) computer languages before the machines could be used. Even then a great deal of time and effort was needed to perform the simplest functions. Before long Gates was an expert at working the school's computer. After his graduation from secondary school, Gates was accepted by the three top universities in the USA Princeton, Harvard and Yale. He chose Harvard and began classes there the next autumn, majoring math. But he was still obsessed (占據(jù)心思) with computers and spent as much time in the computer laboratories as he did in the lecture halls.

        By 1975, Gates and a partner, Paul Allen, had developed a software program called BASIC. This was not the first program ever created, but its inventors were the first to decide that people who wanted to use it should pay for it.

        BASIC was a success because until it came along, there had been no efficient way of getting computers to carry out instructions. Although he had not completed his degree, Gates left university and went to work full time for the new company he had formed called Microsoft.

        His next project was the software program that made him famous and very rich. It was called DOS, short for Disk Operating System, and it was purchased (購(gòu)買(mǎi)) by 113M in 1980. Today it is the operating system used in more than 14 million personal computers around the world.

        As chief executive office of Microsoft, Gates is known as a bright man, but one who is not easily satisfied. He is quick to criticize (批評(píng)) his staff and hates to be questioned about decisions he has made. He was regarded as a loner and unfashionable boring computer nut until his marriage to Microsoft manager Melinda French on New Year's Day 1994. Yet to most people now, Gates is a person who is, in spite of his great wealth, humble (謙恭) and ordinary. He spends his money carefully. He eats in fast food restaurants and flies economy class. And when praised for Microsoft's great success, he has been heard to say. “All we do is put software in a box and if people see it in the stores and like it, they buy it. “

    1．When he was a teenager, Bill Gates wanted to be a  ________.

        A. teacher

        B. doctor

        C. businessman

        D. professor

    2．When Gates went to Harvard, he ________.

        A. was interested only in math

        B. spent most of his time in computer laboratories

        C. developed the first computer software program

        D. divided his time between his math studies and the computer laboratories

    3．Before the development of BASIC, ________.

        A. no one was interested in computer software

        B. software programs were not considered commercial projects

        C. software programs were very expensive

        D. no one wanted to pay for computer software

    4．When the writer says, “Bill was regarded as an unfashionable boring computer nut”, he means ________.

        A. Bill was so strong-minded that no one could change his mind

        B. the only thing that could interests Bill on his life was computer

        C. Bill was such a boring young man that nobody would like to talk to him

        D. Bill couldn't work out the boring computer problems

    5．Most people think Gates is ________.

        A. a crazy person

        B. a person obsessed with making money

        C. someone who spends money freely

        D. a quite common, normal person

    Einstein, a great scientist of the age, was almost as strange as his Theory of Relativity.
    Once, while riding a street car in Berlin, he told the conductor that he had not given him the right change. The conductor counted the change again and found it to be correct, so he handed it to Einstein, saying, “The trouble with you is that you don’t know your figures.”
    Einstein said that there were only twelve people living who understood his Theory of Relativity although a good many books had been written to explain it.
    He had nothing but contempt(蔑視) for the things most people set their hearts on --- for fame and riches(財(cái)富) and luxury(奢華).
