VIII. Read the following passage and mark the letter A, B, C or D on year answer sheet to indicate the correct answer to each of the questions.

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, evey 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 potentiallyharmful? The answer is radiation. High-tech machines can detect very small amounts of radiationfrom 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.

1. According to the passage, cell phones are especially popular with young people because________.

A. they keep the users alert all the time

B. they make them look more stylish

C. they can not be replaced by regular phones

D. they are indispensable in everyday communications.

2. The word “means” in paragraph 1 most closely means________.

A. meanings B. expression C. transmission D. method.

3. Doctors have tentatively concluded that cell phones may________.

A. change their users’ social behaviors B. change their users’ temperament

C. cause some mental malfunction D. damage their users’ emotions.

4. “Negative publicity” in paragraph 2 most likely means _______.

A. widespread opinion about bad effects of cell phones

B. information on the lethal effects of cell phones

C. the negative public use of cell phones

D. poor ideas about the effects of cell phones.

5. The changes possibly caused by the cell phones are mainly concerned with_______.

A. the smallest units of the brain B. the mobility of the mind and the body.

C. the resident memory. D. the arteries of the brain.

6. The man mentioned in the passage, who used his cell phone too often, _______.

A. had a problem with memory B. abandoned his family

C. suffered serious loss of mental ability. D. could no longer think lucidly.

7. The word “potentially” in the paragraph 4 most closely means_______.

A. certainly B. obviously C. possibly D. privately.

8. According to the passage, what makes mobile phones potentially harmful is_______

A. their radiant light B. their raiding power

C. their power of atraction D. their invisible rays.

9. According to the writer, people should_______

A. keep off mobile phones regularly

B. never use mobile phones in all cases.

C. only use mobile phones in medical emergencies.

D. only use mobile phones in urgent cases.

10. The most suitable tittle for the passage could be _______
