     All over the world people enjoy sports; sports help to keep people healthy and happy, and

to live longer.

     Many people like to watch others play games. They buy tickets or turn on their TVs to

watch the games. Often they get very excited when "their" player or team wins.

Some sports are so interesting that people everywhere go in for(参加) them. Football, for

example, has spread(展开)around the world. Swimming is popular in all countries near the

sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China,

Egypt or Italy! And think of people in cold countries. Think how many love to skate or ski

(滑雪) in Japan, Norway or Canada.

     Some sports or games go back thousands of years, like running or jumping. Chinese

wushu, for example, has a very long history. But basketball and volleyball are rather new.

Neither one is a hundred years old yet. People are inventing new sports or games all the

time. Water-skiing is one of the newest in the family of sports.

     People from different countries may not be able to understand each other, but after a

game together they often become good friends. Sports help to train(培养,训练) a person's

character(性格,品格).One learns to fight hard but fight fair, to win without pride and to lose

with grace(胜不骄,败不馁).
