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that an unpublished study had found that mobile phones cause memory loss.And a British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一rather than less一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.

It_______that mobile phones might be good for health.
A:different messages
B:is hoped
C:public attention
D:solid evidence
E:attracted public attention
F:public anxiety

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.

Mobile Phones:Change Our Life

In the case of mobile phones,change is everything. Recent research indicates that the mobile phone is changing not only our culture,but our very bodies as well.
First,Let's talk about culture.The difference between the mobile phone and its parent一the fixed-line phone,is that a mobile phone corresponds to a person,while a landline goes to a place.If you call my mobile,you get me.If you call my fixed-line phone,you get whoever answers it.
This has several implications.The most common one,however,and perhaps the thing that has changed our culture forever,is the"meeting"influence.People no longer need to make firm plans about when and where to meet.Twenty years ago,a Friday night would need to be arranged in advance.You needed enough time to allow everyone to get from their place of work to the first meeting place.Now,however,a night out can be arranged on the run.It is no longer"see you there at 8", but"text me around 8 and we'll see where we all are".
Texting changes people as well.In their paper,"Insights into the Social and Psychological Effects of SMS Text Messaging",two British researchers distinguished between two types of mobile phone users:the"talkers"and the"texters”一those who prefer voice to text message and those who prefer text message to voice.
They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality.Texters were likely to report that their family would be surprised if they were to read their texts.This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.
Another scientist wrote of the changes that mobiles have brought to body language.There are two kinds that people use while speaking on the phone.There is the"speakeasy":the head is held high,in a self-confident way,chatting away.And there is the"spacemaker":these people focus on themselves and keep out other people.
Who can blame them?Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So,it is understandable if your mobile makes you nervous.But perhaps you needn't worry so much.After all,it is good to talk.

In spite of all the problems,mobile phones still bring to us lots of conveniences.
A:Right
B:Wrong
C:Not mentioned

答案:C
解析:
本题给出的信息是错误的。原文是:"If you call my fixed-line phone, you get whoever answers it."
