In many places, it is actually considered unusual not to use one. In many countries, cellphones 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.

* Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.   “They told me I could never walk again. But when I listened to music, I forgot all about the pain. I found the strength I didn’t know I had.”Ninety-two-year-old Tina Goodman, who regained her ability to walk, thanks to music.   This is just one of the many stories in Fettaro’s book “The Healing Power of Music” . Fettaro tries to show just how important music is in our lives and how it can help us to be healthy and happy.   According to Fettaro, music can make sick people again. In fact, his book comes with a CD of recordings, each one specially designed to help with a number of health problems.   Fettaro, e well-known music therapist, promises that by reading his book, you will be able to develop the healing power of music in your life. He says this will help you fight headaches and back pain, as well as reduce stress, high blood pressure, and many other common illnesses.   : What was Tina Goodman’s problem?   Certainly, I accept that listening to certain types of music can help with particular problems, such as stress. I am also comfortable with Fettaro’s claim that by reading his book, you’ll be able to create a peaceful enviroment to help you relax in your home. I found the relaxation and breathing techniques very useful. Similarly his claim that music help you sleep better seems reasonable. Yet when he goes on to promise his music therapies will help cure depression and even cancer, he begins to sound a little bit unbelievable.   Nevertheless, for those of you who are interested in the power of music to heal, this is a great book to buy.
