Thanks to advanced technology, cell phones have become more and more popular in our life. From my point of view, cell phones have improved modern life. First and foremost, cell phones are a good means of communication. Thanks to them, people can keep in touch with their family, their relatives and their friends regardless of the distances. For example, only by a cell phone can you daily talk to or chat with your friends who live very far away from you. In the second place, cell phones are also good for every angle in life. Thanks to its small size, people can take them everywhere at anytime. For example, in business, people can make a deal with their countership by a video chat on a cell phone rather than have a meeting face to face. This is very convient especially for their partner living abroad. Moreover, cell phones are a necessary for people’s entertainment. To illustrate, after a busy day at work or at school, they can listen to music or play games or watch a movie, as a result, they may feel more relaxed and more energetic to many things such as doing housework, homework and so on later. Last but not least, it is estimated that almost all of the people who use cell phones are teenegers. Therefore, no one can deny that cell phones have minute by minue become an indispensable in teenegers’ routine. In reality, cell phones help teenagers to study better and better. For example, before an exam, instead of being up to all night to reivise so many lessons they had studied, teenagers can benefit greatly from cell phones. They can try on some tests on Internet, search for information they want or look into some parts in the lessons which they don’t take in too much. Seeing that the speed of Internet is very fast, students can acquire a lot of knowledge in a very convient way. While I appreciate the advantages of the cell phones, I think that they also have some drawbacks including having bad effects on people’s mind, causing some diseases and so on. All in all, it is immediately obvious that cell phones make out life more and more modern, hence people should take them into consideration to make our life better and better

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 - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made 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, medical studies have shown 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 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.

Doctors have tentatively concluded that cell phones may ____________.

A. change their users’ temperament

B. have damaged their users’ emotions

C. cause some mental malfunction

D. change their users’ social behaviours
