　　Dear Father and Mother,

　　Zhouhui is my deskmate. He’s tall and strong. He is very clever with his hands and can fix almost anything. In study he is good, too. He works very hard and usually gets good grades. Unlike many others, Zhouhui doesn’t smoke or drink. And he never comes back to the bedroom very late.

　　Zhouhui is my roommate, too. Everybody says he is a very good guy. And we all like him very much.

　　Dear Mr.Liu,

　　I learn with dismay from today’s paper that a severe earthquake happened in your city two days ago. It was indeed the sharpest one ever experienced and produced great effect on people’s life there. Your neighborhood was in the area of the earthquake center. I do hope you and you family have escaped without harm.

　　Looking forward to hearing from you in detail.

　　Yours sincerely,

　　Li Guoliang
