One afternoon, while I was doing my homework, then suddenly I heard someone knocking at the door. I rose my head, looking out of the window to see who it was. A man of about 50 broad shoulders and glasses were standing on the door steps. He was tall, wearing in an old army coat. He grew a wild beard. A big black hat was pulling forward over his eyes so that it was hard to see her face clearly. His shoes were old but worn out. It was a big hole in one of his socks. He had with him a black box in one hand. Only after I took a few more closer looks at him I recognize that he was my neighbor ten years ago.

It happened in a morning that I was walking in the street .I ate up a banana and threw their peel on the corner of the road. Short after that I heard a scream behind .I looked back to see what was happened .A little girl about 8 years old fell down and the banana peel was exactly under her left shoes . She stood up without cry .Then she picked up the banana peel and ran toward the dustbin .On that moment ,I realized my fault , and went to apologize her for that ,but my vanity (虚荣心)prevented me . The little girl had taught me a good lesson by her action.. And now, after I do everything, I’ll think carefully whether it’s right or wrong. I’ll do my best to be in good habits and qualities.

Dear Ralph,
I am an university student. I once thought life at the university must be excellent,
but now I changed my mind. I have three roommates, and I was the last one
to move into the dormitory. Last term, I got along peacefully and happy. But I find
they are not willing to be with me now. They don’t talk with me, and they’ve
become cold toward me. Many time, I have wanted to talk with them about how I
felt like, but I failed to find an opening. When leaving alone, I always recall this
sadness. But I am an honest student. Why don’t I win true friendship?
Dear Mary,
I receive your E-mail just now. Don’t worry about me. I’m getting on well with my research work in the lab. But to my greatly surprise you say you will give up learn English. The reason is because you have not done well in it recently and you have lost interests. I’m afraid I couldn’t agree with you . I know it is difficulty to learn English, and English is widely used in the world today. It will be important tool in our future work. Beside, it is becoming more and more important in our daily life. If you study hard, you will be succeed. Do remember that where there is a will, there is a way. I’ m looking forward to hearing good news from you.
Yours,
Li Hua
