    Cell Phones : Hang Up or Keep Talking?

    Millions of people are using cell phones today.In many places it is actually considered unusual not to
    use one.In many countries,cell phones are very popular with young people.They find that the phones are
    more than a means of communication一having a mobile phone shows that they are cool and connected.
    The explosions around the world in mobile phone use make some health professionals worried.Some
    doctors are concerned that in the future many people may suffer health problems from the use of mobile
    phones.In England,there has been a serious debate about this issue. Mobile phone companies are worried about
    the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your health.
    On the other hand,why do some medical studies show changes in the brain cells of some people who use
    mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning
    equipment. In one case,a traveling salesman had to retire at a young age because of serious memory loss.He
    couldn't remember even simple tasks.He would often forget the name of his own son.This man used to talk
    on his mobile phone for about six hours a day,every day of his working week,for a couple of years. His family
    doctor blamed his mobile phone use,but his employer's doctor didn't agree.
    What is it that makes mobile phones potentially harmful?The answer is radiation.High-tech machines
    can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is
    some radiation,but they say the amount is too small to worry about.
    As the discussion about their safety continues,it appears that it's best to use mobile phones less often.
    Use your regular phone if you want to talk for a long time.Use your mobile phone only when you really need
    it. Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones
    may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile
    phone too often.

    People buy cell phones for the following reasons EXCEPT that_________.
    A:they're popular
    B:they're useful
    C:they're cheap
    D:they're convenient

    答案：C
    解析：
    由第一段第三句“cell phones are very popular”可知A项正确。由最后一段第四句“very useful and convenient”可知，B、D两项正确。故选C。
    根据语境可知detect的意思是“发现，查明”。故选C。
    由第三段可知那位销售员是因为严重的记忆问题而退休的，他连简单的任务都记不 住，故选D。
    由第四段最后一句可知，移动公司承认手机有一些辐射，但他们认为辐射的量很小，无 需担心。
    由文章最后一句可知，作者建议大家尽量少使用手机。 第三篇 本篇文章讲述了对杭微生物的杭力应引起注意。
