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 travelling 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
According to the passage, cell phones are especially popular with young people because
A. they keep the users alert all the time
B. they are indispensable in everyday communications
C. they make them look more stylish
D. they cannot be replaced by regular phones
Cell phones have been popular in Japan since the early 1990s, but it was not until 1999 that their use really took off. The age of cell phones has emerged, but with it come problems.
Cell phones are used on buses and trains, in restaurants, and in all areas of life. They causeproblems when they ring during meetings, concerts, wedding, or even funerals. What’s more, people speak loudly in public, and students read and text messages during lessons. More seriously, when a cell phone is used near a person using a pacemaker to regulate his hearbeat, its radio waves may interfere with the functioning of the pacemaker.
Now, something is being done to solve these problems. In many places, new technology is being used to block cell phone calls. Airline passengers are requested to stop using cell phones while on board. Concert halls ask their audience to switch their phones to the silent mode. However, phone users fear that if they do not answer their phones, they will lose valuable business opportunities. That’s why many do not turn off their phones even when they are asked to.
