I was very happy yesterday. In the afternoon,I helped my friend to clean his room yesterday. His room is not very clean. There are many things in it. And the things are not in the right place (they shoud be). I became very happy after i helped him. I always think that helping others is a good thing. Helping others makes me happy. My mother and father have told me before that I shoul be glad to help others.
不知道你的具体要求,所以先写了简单的,要是需要复杂的可以再联系.
