Look at the center circles of Diagram (图) A and Diagram B.  Which of the centre circles looks larger? 
Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.
Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. 
"What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret (解读) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误). 
Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.

Look at the picture. What can you see? In the picture there is a big table with a lot of things on it. There are three bottles of orange juice, two glasses of milk, some bread, cakes and so on. look, there is a cat under the table. It’s Kate’s cat. Its name is Mimi. I think it like them very much.

Look at the diagram. It   ?    something of home computer used by a group of young people. We asked thirty young people between fourteen and eighteen. We asked them how much  ?   they usually spent on their computers in a week, but we were most interested in  ????   they used their computers for.

The usual time spent on a computer in a week was about twelve hours, with  ???? user about thirty-two hours, and the lowest user only five hours.

All the children said they usually used computers  ??   . Fourteen children told us they did some word processing (文字处理)  ??    . Only two of them said computers helped with their lessons, and eight people told us they kept addresses and phone numbers on their computers or used   ??   as diaries. Only three people said they were learning to make computer programmes and nobody looked up databases(数据库). None of them used computers for any  ??   use.

The results show that computer use is quite high among 14～18 year old. They also show quite clearly that computers  ??   by most young people as little more than game machines. The only other great uses are for word-processing and  ??  address lists. Though computers are common in the homes of young people, they have not yet become useful in everyday life.
