Do you think there is too much noise in our city? If you live near an airport，you will be unhappy because of a plane often make a loud noise．The sound of planes or heavy vehicles is likely to cause deafness if heard continuously（不断地）．
However, most people in our city do not seem to mind noise. They like to enjoy music when they are doing uninteresting jobs．It is a new danger because pop music，when played through powerful amplifiers（放大器），can reach 120 decibels（120分贝的）at a distance of five feet．A continuous noise of over 85 decibels can cause deafness．It was discovered that many young people in America could hear no better than 65-year-old people．
In the past we used to think that only workers in very noisy places would become deaf．For example，when newspapers and books are being printed，the noise level is over 85 decibels，and some of the workers become deaf．Today，however，scientists believe that 10 percent of the workers in Britain are being deafened by the noise．
Sometimes noise of less than 85 decibels can make some people tired and stressed．We all know that too much noise makes life difficult and unpleasant．It can do great harm to people's health and prevent people from working well．Workers in noisy offices are not as efficient（效率高的）as those in quiet offices．Noise makes people less efficient．Can anything be done to reduce or control noise?
In Britain the government has made several laws to reduce noise．Th
ough the government has spent a lot of money in making airports and main roads quieter，many people think that there are still not enough laws．For example，there are no laws to control the noise of machines．In Japan，America and Norway there are such laws．As a result，workers can be given compensation（赔偿）if they become deaf．

Mary picked up a pencil and a piece of paper，saying，“Now，you want to earn money for the autumn camping trip，right?” Tom，her brother，nodded．He wasn’t able to go last year because he hadn’t earned enough money during the summer．This year he came up with a plan．
He made a necklace for his mother that everyone admired．They were surprised to learn that Tom had made it for her．Why not make more necklaces and sell them?
“OK，” said Mary，“The first thing you need to do is to figure out（计算）how much you have now．’’
“I have $20.00 in the bank，and $7.25 in my room，” explained Tom．
“That gives you a total of $27.25，” said Mary，“That is called your capital．The next thing you need to know is how much it will cost you to make each necklace．”
“Well，the pet shop will give me all the feathers the birds lose．I'll have to buy the beads（小珠子）and string，” said Tom．

CAPITAL $27.25
EXPENSES Feathers no cost
String for 10 necklaces $ 2.50
Beads for 10 necklaces + $ 15.00
Total $ 17.50
“How much do you think you can sell such a necklace for?” asked Mary．
“Hmm，” Tom looked thoughtful and said，“There's a shop in town that sells almost the same kind of necklace for $ 7.50．If I charge（要价）$ 6.00，people will think that's a bargain．”
“OK．If you sell each necklace for $ 6.00，you'll make a good profit（利润）on each then，” said Mary．
“Hurray!” Tom cried，“If I sell 20 necklaces，I'll have enough from the profit for the camping trip and $10.00 left over．”

It seems to be strange to you there is a blind spot(点) on the eyes. Here is an interesting experiment that can make something disappear, when one eye is open.
Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.
Why does the letter disappear? It is because there is a blind spot on the eye. When the image of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.

How often one hears children wishing they were grown-ups, and old people wishing they were young again. Each age has its pleasures and its pains(痛苦), and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets(后悔).
Childhood is a time when there are few responsibilities(责任) to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What’s more, life is always giving new things to the child--- things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is repeatedly being told not do something or being punished for what he has wrongly done.
When a young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to as a child, he will go hungry. And if he breaks the laws of society(社会) as he used to break the laws of his parents, he may go to prison. If, however, he worked hard, keeps out of trouble and has good health, he can have the greatest happiness of building up for himself his own position(地位) in society.
1.What is the happiest person according to the passage?
A. A child who can do whatever he likes.
B. An old person who lives in a comfortable life.
C. A grown-up who no longer expects other to pay for him.
D. A person who never wastes his time in his whole life.
2.Which of the following is true, according to the second paragraph?
A. Life for a child is fairly easy.
B. A child is always loved whatever he does.
C. If much is given to a child, he must do something in return.
D. Only children are interested in life.
3. What is the main idea of the passage?
A. Life is not enjoyable since each age had some pains.
B. Young men can have the greatest happiness if they work hard.
C. Childhood is the most enjoyable time in one’s life.
D. One is the happiest if he can make good use of each age in his life.
4. What will the fourth paragraph most probably discuss following this passage?
A. Examples of successful young men.
B. How to build up one’s position in society.
C. Joys and pains of old people.
D. What to do when one has problems in life.
