【题目】 This year, about one hundred teenagers from all over China will spend one year in American homes. They will attend schools and meet teenagers in US., and have a new understanding of America. At the same time, about one hundred American teenagers will come to China to learn Chinese and get a new understanding of China.

A 15yearold exchange student, Fred, spent last year in China with Li Hua's family. In turn, Li Hua spent a year in Fred's home in America.

Students stood up respectfully(尊敬)when the teacher entered the classroom. They took fourteen subjects instead of six in the United States. There were almost no outside activities.

Family life, too, was different. The father's word was law, and all activities were around the whole family rather than individuals(个人)

“Back home, you pick up some friends in a car and go out and have a good time. But in China, you walk home and you have to finish your homework first.”

At the same time, in America, Li Hua, a friendly Chinese boy, was also forming his idea.“I suppose I should criticize(批评)American schools.”he says, “It is much too easy by our level.
