It has a long history among almost all the different groups of people but especially for children. In 1926, a top was discovered proving that the game existed(存在) over 4,000 years ago. A whip is used to spin the top. A top can be made of stone, wood or bamboo. While the tops used by children are small and often colorful, those used in competitions are quite different. The top for formal games usually weighs around 0.45 kilogram and the whip is at least 2 meters long. As you can guess, it is difficult to handle (操纵) them. The top spinning was once a worldwide popular street game for children.The rope of the whip is wound (缠绕) around the top that is put on the ground of a smooth surface which may even be ice. The whip is pulled back causing the top to spin. It is kept spinning and momentum (冲力) increases with the help of the whip. In China this simple pastime (休闲活动) has been developed into a competitive sport.Competition rules are different in many ways. In one, often called a “battling tops (斗陀螺)”, two players cause their tops to hit each other in an effort to make the opponent’s top fall—the one that stays spinning is the winner. Another is to get the top to spin over obstacles (障碍物), a game requiring great skill and attention; again the winner is the player whose top spins the longest. ( )1. What happened in 1926 according to the passage? A. The top game started. B. The first top was created. C. An over 4,000-year-old top was found. D. Different kinds of tops were made. ( )2.

Children wear colorful clothes when playing with tops. ( )3. What’s the purpose of writing this passage? A. To introduce a traditional sport. B. To tell people to go f or sports. C.
