The Story about Growth is my favorite American TV play because it is very interested. The play tells humorous stories that happen in Mr Green’s family. With such stories it make people think about life, but therefore attracts the audience. It is also a window from that we can learn about American society. And there are many meaningful things that worth thinking of, such as the relationship between parents and children in a lot of American family. It is quite different from that in China. The play is very popular. We’d better not to miss the chance to enjoy it.
