| The Story about Growth is my favorite American TV play because it is very interested . The play tells humorous stories that happen in the Green's family. With such stories it make people think about life, but therefore attracts the audience. It is also a window which we can learn about American society. And there were many meaningful things that are worth think of,such as the relationship between parents and children in a lot of American family. It is quite different from those in China. The play is very popular. We'd better not to miss the chance to enjoy it. | 1._______ 2._______ 3._______ 4._______ 5._______ 6._______ 7._______ 8._______ 9._______ 10._______ |
