Since we go to school, the teachers educate us to be a better person, they tell us that we must study hard, so that we can be the useful person. Many students confuse about what is the useful person. In my opinion, the useful person must have the good merit. A person with the kind heart is favored by everyone and he has the sense to serve others. The bad person will bring danger to others, even to the society. The most important thing of the useful person is to make a contribution to the society. They will make full use of their knowledge and be proud of serving for the society. Our premier Zhou stated his purpose of learning knowledge was to make our country rise. He did it and he became the great person. Becoming the useful person is not easy, we should fight for it. 
从我们上学起，教师就教育我们要成为一个更好的人，他们告诉我们要努力学习，这样才能才成有用的人。很多学生困惑于什么是有用的人。在我看来，有用的人一定要有好的品德。一个好心的人才会被大家喜欢，然后才有意识要为大家服务。不怀好意的人会给大家甚至社会带来威胁。对于有用的人来说最重要的就是为社会做贡献。他们会充分发挥学到的知识，并且为服务社会而感到自豪。我们的周总理表明读书的目的就是为了祖国的崛起。他做到了，成为了伟人。成为有用的人不容易，我们要为之奋斗。
