A Few Remarks on petition

petition is a mon phenomenon in our.social life. We pete when we play games, we try to do better than others in our study, and there is constant petition for jobs, customers, money, and so forth. We can say, to somee cxtent, petition is one of the motive forces of the devdopment of society.

And we often find petition and cooperation at the same time. Think of a baseball game, each team is peting with the other team. But each member of the teatn is cooperating with his or her teammates. In most casos, we can't do petition without cooperation. Thus tbey are equally important.

While we are advocating petltion, we can't fet cooperation. Nothing is to becarried to extremes. Pure and exclusive petition leads to failures. petiton together with cooperation help us a great deal in obtaining our goals and satisfying our needs,especially in modernizing our country.
