写作

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。  

     Competition is common in every field of life.For example, the Olympic Games is the most famous

competition in the world.In the fourhundredmeter swimming race, the swimmers plunge into the water at

the signal.Each swings his or her arms and legs and tries his or her best to be the first.Also there is the

competition for jobs, for promotion, for customers, and so on.We can say, in a certain sense, competition stimulates (激励) people's interest in work and helps society to go forward.

     We often find that competition goes hand in hand with cooperation.Take a volleyball match for

example.The members of the team cooperate with each other.One serves the ball, then another passes the ball to a certain height for a still other to hit it over the net while the other members try to block it on its

return.It requires good team work to win the game.

     While we advocate (提倡) competition, we cannot forget cooperation.Human beings are social beings.No one can exist alone in the society.If you want to play the game well, you have to play with others.You

cannot play singlehanded and win.You have to cooperate with your playmates, who may make the social

ladder for you to climb to the top.From cooperation we get help and understanding.With cooperation the world is progressing at peace and in harmony.
