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.

Hands play an important part in our daily life. But do you know which of your two hands you use more? Very few people use both hands equally well.  Most of us are right-handed.  Only about five people out of a hundred are left-handed.  New-born babies can take hold of things with either of their hands, but in about two years they usually use their right hands.  Scientists don’t know why this happens.

Monkeys are our close relatives in the animal world. Scientists have found that monkeys like to use one of their hands more than the other, but it can be either hand.  There are as many right-handed monkeys as left-handed ones.  Next time you visit a zoo, watch the monkeys carefully, you will see that some of them will use their right hands and others will use their left hands.  But most of the people use their right hands better and this makes life difficult for those left-handed people.  We live in a right-handed world. 

1.How many people among 100 people use their left hands better?
