Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live ------ in the middle of a modern city or a far-away village ---- the chances are that you will be disturbed by jet planes, transistor radios, oiled-powered engines, etc. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be a very frightening experience for a human being. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums. The noise level in some discs is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration suggested that although a lot of people say that any noise disturbs their concentration, what really influences the ability to concentration is a change in the level of noise. It goes on to say that a background noise which doesn’t change too much(music, for example many even help to concentrate.)

I hear many parents saying that their teenagers are rebellious (反叛的). I wish it were so. At your age you ought to be growing away from your parents. You should be learning to stand on your own two feet. But take a good look at the present rebellion. It seems that teenagers are all taking the same way of showing that they disagree with their parents. Instead of striking out bravely on their own, most of them are trying to seize at one another’s hands for safety.
They say they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow reason for thinking or acting in thus-and-such a way is that the cords is doing it. They have come out of their cocoon --- into a larger cocoon.
It has become harder and harder for a teenager to stand up against the popularity wave and to go his or her own way. Industry has firmly opened up a teenage market. These days every teenager can learn from newspapers and TV what a teenager should have and be. And many of today’s parents have come to award high marks for the popularity of their children. All this adds up to great difficulty for the teenager who wants to find his or her own path.
But the difficulty is worth getting over. The path is worth following. You may want to listen to classical music instead of going to a party. You may want to collect rocks when everyone else is collecting records. You may have some thoughts that you don’t care to share at once with your classmates. Well, go to it. Find yourself. Be yourself. Popularity will come --- with the people who respect you for who you are. That’s the only kind of popularity that really counts.
