anytime and anywhere.
In the U.S., more than 90 million people use mobile phones. Many of those people are children. For
children, mobile phones are more than phone calls. They are fashionable.
Most mobile phone users don't think about the health problems caused by mobile phones. Some scientists
say that mobile phones give off radiation (辐射) that might be bad for users. One recent study shows that
mobile phone radiation might raise a person's chance of getting some kinds of cancer (癌症). Other
scientists say mobile phones don't threaten people's health. They say that they have not found any link (联系) between mobile phone use and cancer.
Scientists say that people can protect themselves from mobile phone radiation. One way is to use a
headset (耳机). Or people can make shorter calls.

phones are stolen, some students fight with and hurt one another, and others are knocked down by the fast
running bikes or cars.
These problems arc common on campus. I think there are three causes for these. Firstly, some students
do not take good care of their properties. They are still young and not careful enough. Secondly, some
students want to do everything well. They want to be the winners in exams, and they also want to be the
winners in fightings. And thirdly, the campus guards (保安) do not carry on their duties well. They don' t
regulate the traffic in the busy hour.
In order to have a secure campus, all the students should be very careful about their properties. They
should also mind their behaviors (举止) and act politely. The campus guards are supposed to be devoted
(致力于) to the security on campus, and it is their duty to safeguard (维护) a secure campus to help provide
a good environment for the students.

Mobile phones and the Internet have improved our life in many ways. However, along with improvements, they also brought a number of worrying problems.

If you go to the Hong Kong History Museum, you will see a photo taken in 1989 of a man holding a mobile phone. The phone is the size of a small handbag and when the person is speaking into, it, it covers half of his face! In sixteen years, people have entered the mobile phone age. Some mobile phones these days are so small that they can fit right into your hand. If these changes have taken place(发生) in just sixteen years, what kind of mobile phones will be used in the future?

查看习题详情和答案>>the TV or her boyfriend, she said "the phone". Personally, I could do without the phone entirely, which
makes me unusual, because the telephone is changing our lives more than any other piece of technology.
Point l. The telephone creates the need to communicate, in the same way that more roads create more
traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to
the very people she has been at school with all day. If the phone did not exist (存在), would she have
anything to talk about?
Point 2. The mobile phone means that we are never alone. "The mobile saved my life," says Crystal
Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she
managed to make the call that brought the ambulance (救护车) to her rescue.

to ring his sales staff all round the world at any time of day to ask where they are, where they are going,
and how their last meeting went.
Point 4. The telephone separates us. Antonella Bramante in Rome says, "We worked in separate offices
but I could see him through the window. It was easy to get his number. We were so near, but we didn't meet
for the first two weeks!"
Point 5. The telephone allows us to reach out beyond our own lives. Today we can talk to several complete
strangers at the same time on chat lines (at least my daughter does. I wouldn't know what to talk about). We
can talk across the world. We can even talk to astronauts while they're space-walking. And, with the phone
line connected with the computer, we can aceess (进入) the Intemet, the biggest library on Earth.
