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.

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.
Mary wrote on the piece of paper:
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.

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.Though 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.
