                                  Chess

  Chess must be one of the oldest games in the world .An Arab traveler in the year 900 wrote that it was played “long long ago”. Chess was probably invented in India, and it has been played everywhere from Japan to Europe since 1400. The name “chess” is interesting. When one player is attacking the other‘s king, he says, in English, “check”. When the king has been caught and cannot move anywhere, he says “check mate”. These words come from Persian (波斯人). It means “the king is dead”. That is when the game is over, and one player has won.

  Such an old game changes very slowly .The rules have not always been the same as they are now .For example ,at one time the queen could only move one square (方块)at a time . Now she is the strongest piece on the board .It would be interesting to know why this has happened! Chess takes time and thought, but it is a game for all kinds of people. You don’t have to be winner in order to enjoy it. Two people sitting at the same table do not always play it. The first time the Americans beat the Russians was in a match played by radio. Some people are able to play with many people at the same time. One man played 400 games! It is said that some people play chess by post. This must make chess the slowest game in the world.

                        C  Snails

  We’ve talked about snails (蜗牛) and their slow move . But much of the time snails don’t move at all. They’re in their shells (壳)---sleeping .

 Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover .Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time .And it spends all the winter months in its shell, asleep.

 In spring the snail wakes up .Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can’t see very well. Its eyes ,at the ends of the top feelers (触角)are very weak . But its sense of smell is very strong. It helps the snail to the new greens. Then the snail’s little mouth goes to work.

A snail’s mouth is no longer than the point of a pin(针) . Yet it has 256,000 teeth! The teeth are so small that you can’t see them. But they do their work.. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.

Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.
