帮忙找一些外国与中国不同的地方(用英文写)

One of my best friends is an American girl. She likes sitting on the grass. When she saw me in the open air, she also let me sit on the grass. And I will say: “we should protect the plants. You’d better not sit on it.” But she will say: “in American, we all sit on the grass.” American think plants are serving for people, but Chinese people think we should protect the plants. This is one of the differences between foreign people and Chinese people.

our foreigner teacher said the Anerican can get married at 18. the family is a big one too .One couple can have more than there children .and we have a big difference in education
