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.

On the safety issue of mobile phones,the manufacturing companies______________.
A:deny the existence of mobile phone radiation
B:develop new technology to reduce mobile phone radiation
C:try to prove that mobile phones are not harmful to health
D:hold that the amount of radiation is too small to worry about

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.

It is suggested that mobile phones should be used to
A:give the address of the nearest hospital.
B:show bus and train timetables.
C:arrange delivery of mails.
D:cure diseases.
