【答案解析】
Competition is common in every field of life . For example , the Olympic Games is the most famous competition in the world. In the 400 meter 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 people"s interest in work and helps society to go forward.
We often find that competition goes hand in hand with cooperation . Take, for example , a volleyball match. The members of the team cooperate with each other. One serves the bail. 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 teamwork to win the game.
While we advocate 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 single-handed 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 mutual help and understanding. With cooperation the world is progressing at peace and in harmony.
