Nowadays,competition and co-operation are the important topics. Some people agree that competitive relationship is good for children. Whatever, co-operation is the key of growing for children. Sometimes children have not sense of efforts,competition can makes them improve their learning consciousness. When children received failure,competitions’ behavior can inspire them and teaches them how to avoid the failure.As we can see,competition can find children’s disadvantages.However,due to children’s age is no enough to adjust attitude,a rate race could lead to sense of inferiority. Turn to co-operation. Co-operation would make children adjust the teams’ working, so they can do better in college than those people who lack of co-operation, because we all know that in college students have to do homework with others frequently. At the same time,children would gain the sense of responsibility by the cooperation with others. From my personal point of view, co-operation is more useful than competition for children.because competing with the excellent people lead to their unsteady emotions while cooperation could give temperate ways to exposure those outstanding people. Competition is vital, but striving in a long and steady state is more essential.
