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.

Antifreeze is a liquid(液体) that is added to water to keep it from freezing. When water freezes and turns to ice,it expands(膨胀).The force of water expanding is so great that it will break the hardest metal.Water is used in car engines(发动机) to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary.
Water freezes at 0℃;the usual kind of antifreeze will not freeze until the temperature is-40℃.A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at-18℃;four parts of water and five parts of antifreeze reduce this to -22℃.
Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol.

A.antifreeze | B.water | C.alcohol | D.ethylene glycol. |
A.0℃ | B.-18℃ | C.-22℃ | D.-40℃ |
A.keep alcohol in water |
B.stop ice from becoming water |
C.make the freezing point of water lower |
D.raise the freezing point of water |

Singapore, July 12-many people enjoy chewing(咀嚼) gum, but in 1992 Singapore decided to make it against the law. The government said that people were not careful about throwing away used gum. Instead, they dropped it on sidewalks and on the streets where it made a big mess. Chewing gum also got stuck in the doors of the underground trains so that the doors didn’t close properly. This meant the trains didn’t run on time. Singapore said that people had to give up chewing gum or pay a lot of money to the government. During the time without chewing gum, the streets and underground trains of Singapore were clean.
Now the government of Singapore is changing the rules a little. Some dentists say that chewing sugarless gum can help take care of people’s teeth. Now the government says that people will be able to buy special kinds of gum at drugstores for health reasons. Other kinds of gum are still not allowed.

We send our children to school to prepare them for the time when they will be big and will have to work for themselves.They learn their own language so that they will be able to tell others clearly what they want and what they know,and understand what others tell them.They learn foreign languages in order to be able to understand the people from other countries and make themselves understood.They learn history to know something about human beings they meet every day.What they learn at school is,of course,quite useful,but is that the only reason(原因) why they go to school??
