Cell Phones: Hang Up or Keep Talking
Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one.1. They find that the phones are more than a means of communication – having mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. Mobile phone companies are worried about the negative publicity(负面报道)of such ideas. 2.
On the other hand, signs of change in the issues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. 3. 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.
4. The answer is radiation(辐射). 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 the safety continues, it appears that it’s best to use mobile phones less often.
5. Use your mobile phone only when you really need it. 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.
A. They say that there is no proof that mobile phones are bad for your health.
B. What do the doctors worry about?
C. In many countries, cell phones are very popular with young people.
D. Use your regular phone if you want to talk for a long time.
E. He couldn’t remember even simple tasks.
F. They will possibly affect their benefits.
G. What is it that makes mobile phones potentially harmful?
For some people, music is no fun at all. About 4% of the population is what scientists call “amusic”. People who are amusic are born without the ability to enjoy musical notes. Amusic people often cannot tell the differences between two songs.
As a result, songs sound like noise to an amusic. Many amuics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. In fact, most people cannot understand what it feel like being amusic. Just going to a restaurant or a shopping center can be uncomfortable or even painful. That is why many amusics have to stay away from places where there is music. However, this can result in social loneliness. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify(辨别) this unusual condition.
Scientists say that the brains of amusics are different for those of people who can enjoy music. The difference is complex(复杂的), and it is not connected with poor hearing. Amusics can understand other non-musical sounds well. They also have no problems understanding common speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed(诊断). For years, Margaret felt embarrassed about her music problem. Now she knows that she is not alone. That makes it easier for her to explain. “When people invite me to a concert, I just say ”No, thanks. I’m amusic.’” says Margret. “ I just wish I had learned to say that when I was seventeen and not seventy.”

Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run around the needle without any problems.
Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way. Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.
1.The problem Howe was trying to solve was________.
A. what kind of thread to use
B. how to design a needle which would not break
C. where to put the needle
D. how to stop the thread from getting caught around the needle
2.Thomas Edison is spoken of because________.
A. he also tried to invent a sewing machine
B. he got some of his ideas from dreams
C. he was one of Howe’s best friends
D. he also had difficulty in falling asleep
3.Dreams are sometimes called “secret messages to ourselves” because ________.
A. strange images are used to communicate ideas
B. images which have no meaning are used
C. we can never understand the real meaning
D. only specially trained people can understand them
