cooperation and competition are both important. they are attributes(归因于,属性) which are equally necessary for a person to achieve success in his life.

　　learn to be cooperative. no one likes a selfish, greedy, or arrogant(自大的) individual. however, everyone likes a considerate(体谅的) and cooperative person. everything we do today, whether in doing business or making friends, depend upon our ability to get along with one another. in our society, most tasks demand the cooperation of many individuals so that they can be accomplished effectively. in this situation, we must be supportive(支援的) and cooperative. each person is like a small part of a machine. if only one part is out of order, the machine can’t be running well. besides, transportation and communication systems are rapidly developing and people all over the world can get in touch with each other more easily. it is hard for a person who is isolated(孤立的) from the society to have a deep understanding of the world he lives and to accomplish(实现) a feat(功绩) in his career. cooperation is becoming more and more important for a person to earn a good life.

　　being competitive also has a place in life. if you want to achieve more success and be better than others, you must work harder, study more diligently(勤奋地), and adapt yourself to competition. the desire to succeed and do better than others inspires(激励) us to work harder. if there were no competition, a sports meet would never be exciting and successful, and we would never have champions(冠军的地位).

　　no doubt, we often find there is an inseparable(不可分离的) relationship between competition and cooperation. in a football match, either team is competing with other. but each member of the team is cooperating with his teammates.

　　we cooperate with others to be more competitive; we compete to earn a better environment for cooperation. thus we can make progress(前进) continuously. only competition together with cooperation leads us to realize our goals and satisfy our needs.
