    Mobile Phones : Are They about to Transform Our Lives?

    We love them so much that some of us sleep with them under the pillow,yet we are
    increasingly concerned that we cannot escape their electronic reach.We use them to
    convey our most intimate secrets,yet we worry that they are a threat to our privacy.We
    rely on them more than the Internet to cope with modern life,yet many of us don't believe
    advertisements saying we need more advanced services.
    Sweeping aside the doubts that many people feel about the benefits of new third
    generation phones and fears over the health effects of phone masts(天线竿),a recent
    report claims that the long-term effects of new mobile technologies will be entirely positive so
    long as the public can be convinced to make use of them. Research about users of mobile
    phones reveals that the mobile has already moved beyond being a mere practical
    communications tool to become the backbone(支柱)of modern social life,from love affairs
    to friendship to work.One female teacher,32,told the researchers:"I love my phone.It's
    my friend."
    The close relationship between user and phone is most pronounced among teenagers,
    the report says,who regard their mobiles as an expression of their identity.This is partly
    because mobiles are seen as being beyond the control of parents.But the researchers
    suggest that another reason may be that mobiles,especially text messaging,are seen as a
    way of overcoming shyness."Texting is often used for apologies,to excuse lateness or to
    communicate other things that make us uncomfortable,"the report says.The impact of
    phones,however,has been local rather than global,supporting existing friendships and
    networks,rather than opening users to a new broader community.Even the language of
    texting in one area can be incomprehensible to anybody from another area.
    Among the most important benefits of using mobile phones,the report claims,will be a
    vastly improved mobile infrastructure(基础设施),providing gains throughout the economy,
    and the provision of a more sophisticated location-based services for users.The report calls
    on government to put more effort into the delivery of services by mobile phone,with
    suggestions including public transport and traffic information and doctors' text messages to
    remind patients of appointments."I love that idea,"one user said in an interview."It would
    mean I wouldn't have to write a hundred messages to myself."
    There are many other possibilities.At a recent trade fair in Sweden,a mobile
    navigation product was launched.When the user enters a destination,a route is
    automatically downloaded to their mobile and presented by voice,pictures and maps as they
    drive. In future , these devices will also be able to plan around congestion(交通堵塞)and
    road works in real time.Third generation phones will also allow for remote monitoring of
    patients by doctors. In Britain scientists are developing an asthma(哮喘)management
    solution,using mobiles to detect early signs of an attack.

    Which of the following statements is true?
    A:Modern social life relies significantly on the use of mobile phones.
    B:Mobile phones make romantic communication more difficult.
    C:Mobile phones encourage people to make friends.
    D:Mobile phones enable people of different countries to talk without translation.

    答案:A

    Can Mobile Phones Cause Disease?

    1 "Mobile phone killed my man,"screamed one headline last year.Also came claims
    that an unpublished study had found that mobile phones cause memory loss.And a British
    newspaper devoted its front page to a picture supposedly(假定地)showing how mobile
    phones heat the brain.
    2 For anyone who uses a mobile phone,these are worrying times.But speak to the scientists
    whose work is the focus of these scares and you will hear a different story.According to them,
    there is no evidence that mobile phones cause cancer or any other illness in people.
    3 What we do have,however,are some results suggesting that mobile phones' emissions
    have a variety of strange effects on living tissue that can't be explained by the general
    radiation biology.And it's only when the questions raised by these experiments are
    answered that we'll be able to say for sure what mobile phones might be doing to the head.
    4 One of the odd effects comes from the now famous"memory loss"study.Alan Preece
    and his colleagues at the University of Bristol placed a device that imitated the microwave
    emissions of mobile phones to the left ear of volunteers.The volunteers were just as good
    at recalling words and pictures they had been shown on a computer screen whether or not
    the device was switched on.Preece says he still can't comment on the effects of using a
    mobile phone for years on end.But he rules out the suggestion that mobile phones have an
    immediate effect on our cognitive abilities."I'm pretty sure there is no effect on short-term
    memory,"he says.
    5 Another expert,Tattersall,remarked that his latest findings have removed fears about
    memory loss.One result, for instance, suggests that nerve cell synapses(突触)
    exposed to microwaves become more-rather than less-receptive(感受的)to undergoing
    changes linked to memory formation.
    6 Hopefully,microwaves might turn out to be good for you.It sounds crazy,but a couple
    of years ago a team led by William Adey at the Veterans Affairs Medical Center in California,
    found that mice exposed to microwaves for two hours a day were less likely to develop brain
    tumours when given a cancer-causing chemical.

    Tattersall said for sure that the________over memory loss caused by mobile phones was ungrounded.
    A:difterent messages
    B:is hoped
    C:public attention
    D:solid evidence
    E:attracted public attention
    F:public anxiety

    答案:F

    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
    (扫描)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 mnobile phone only when you really need

    Topic 2:My View on College Students’ Use of Mobile Phones  Questions for reference:  1) What is the phenomenon of college students’ using mobile phones?  2) What might be the advantages and disadvantages of their using mobile phones?  3) What could be done to this problem?

    正确答案: 【参考答案】
    My name is... My registration number is... My topic is: My View on College Students’ Use of Mobile Phones.
    China is becoming a country with the biggest population of mobile phone subscribers and an increasing number of college students are joining the existing users. Statistics show that eight out of ten college students have got one. However, is it necessary for a college student to own a mobile phone?
    In my opinion, there is nothing wrong for a college student to have a cell phone, with is, students will be better connected with friends and parents. What’s more, mobile phones play an important role in graduates’ job-hunting. Therefore, instead of banning the use of mobile phones, schools should take measures to guide an appropriate use of them on campus, For example, students are required to switch off their phones in classrooms and under no circumstances should they use a mobile phone during exams. In some public places, like libraries, a poster can be placed at the entrance to alert library users to switch their phones to vibration mode before they enter the library.
    I believe mobile phones can bring benefits to our students as long as we can make good use of them.

    C

    The Italian scientists’ belief is shared by other scientists.

    D

    The British government inquiry didn’t establish any link between health risks and use of mobile phones.


    正确答案: A
    解析:
    事实细节的识别和判断。根据原文可知,澳大利亚科学家发现手机辐射并不能引发肿瘤的增长(...have shown that radiation from mobile phones does not trigger the growth of tumors),由此可见选项B的说法与原文不符,是正确答案。
    【录音原文】
      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.

    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
    (扫描)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.

    The salesman retired young because_______________.
    A:he disliked using mobile phones
    B:he couldn't remember simple tasks
    C:he was tired of talking on his mobile phone
    D:his employer's doctor persuaded him to

    答案:B
    解析:

    Mobile Phones : Are They about to Transform Our Lives?

    We love them so much that some of us sleep with them under the pillow,yet we are
    increasingly concerned that we cannot escape their electronic reach.We use them to
    convey our most intimate secrets,yet we worry that they are a threat to our privacy.We
    rely on them more than the Internet to cope with modern life,yet many of us don't believe
    advertisements saying we need more advanced services.
    Sweeping aside the doubts that many people feel about the benefits of new third
    generation phones and fears over the health effects of phone masts(天线竿),a recent
    report claims that the long-term effects of new mobile technologies will be entirely positive so
    long as the public can be convinced to make use of them. Research about users of mobile
    phones reveals that the mobile has already moved beyond being a mere practical
    communications tool to become the backbone(支柱)of modern social life,from love affairs
    to friendship to work.One female teacher,32,told the researchers:"I love my phone.It's
    my friend."
    The close relationship between user and phone is most pronounced among teenagers,
    the report says,who regard their mobiles as an expression of their identity.This is partly
    because mobiles are seen as being beyond the control of parents.But the researchers
    suggest that another reason may be that mobiles,especially text messaging,are seen as a
    way of overcoming shyness."Texting is often used for apologies,to excuse lateness or to
    communicate other things that make us uncomfortable,"the report says.The impact of
    phones,however,has been local rather than global,supporting existing friendships and
    networks,rather than opening users to a new broader community.Even the language of
    texting in one area can be incomprehensible to anybody from another area.
    Among the most important benefits of using mobile phones,the report claims,will be a
    vastly improved mobile infrastructure(基础设施),providing gains throughout the economy,
    and the provision of a more sophisticated location-based services for users.The report calls
    on government to put more effort into the delivery of services by mobile phone,with
    suggestions including public transport and traffic information and doctors' text messages to
    remind patients of appointments."I love that idea,"one user said in an interview."It would
    mean I wouldn't have to write a hundred messages to myself."
    There are many other possibilities.At a recent trade fair in Sweden,a mobile
    navigation product was launched.When the user enters a destination,a route is
    automatically downloaded to their mobile and presented by voice,pictures and maps as they
    drive. In future , these devices will also be able to plan around congestion(交通堵塞)and
    road works in real time.Third generation phones will also allow for remote monitoring of
    patients by doctors. In Britain scientists are developing an asthma(哮喘)management
    solution,using mobiles to detect early signs of an attack.

    Teenagers have a close relationship with their mobile phones partly because they
    A:use text messages more than any other group.
    B:are more likely to be late than older people.
    C:tend to feel uncomfortable in many situations.
    D:take mobile phones as an indication of independence from their parents.

    答案:D
