Dear Brad ,
I am a boy in the first grades of a senior high school . I feel uneasily recently . At home I feel like prisoner . I am not allowed to watch TV or surf the Internet . The only thing I have to do it is studying . Every time I got a low mark , my parents will scold me sharply . There's a generation gap among my parents and me , but it's always difficult to communicate . Life are supposed to be colorful and wonderful , isn't it ? How should I devote all my time and energy to the study so as to entering a good university ? I am very unhappy and lost. I need your help .
Best wishes,
Li Ping
I’m glad to write to you. It is near a month since you had left our hospital. I’m still worried about you. How are you get along these days? I think you may be much better now, but I’d better
have a good rest and take good care of yourselves since you are sixty-year-old man. I still remember those days which you helped me to my English. With your help, I make good progress. But to my regret, my English remains very poor through I have made good use of my time. Can you give me some advice on it?
In a summer night in Taiwan, Xiao Hong was going on her way to school happily then suddenly she felt the street was strong shaking. The trees were torn up and many buildings were leaned down to the ground. Even a car was destroyed by the fallen buildings. She was knocked down by a tree before she knew. Two doctors carried him to safety and she was settled down in a tent for treatment. After some time, she had got over. Seeing such many goods from the mainland of China and other countries, she believed all the destroyed houses would be built.
My swimming experience is extreme interesting. There was a time when I swim like a rock. This went on till one day when I was fishing with a friend of mine at nearby pond. I slipped into one. Had my friend not come to my rescue, I would have been drowned. Ever since then, I had come to know the importance of learning to swim. I didn’t attend at any training class but learned it all by myself. Strange to say, I have difficult swimming at all now. Though the way I swim look awkward (笨拙的), at least it can keep me from floating. Thinking of this, I feel quiet satisfied.
My secret of staying young is simple: keeping your mind awake and you will stay young all over. Take an interest in world around you, and learn at least one old thing every day. Don’t think that you are ever very old to go back to school. I know a man who entered medical college in 70. He got his degree with honors and became a famous doctor. Other man went to law school at 71 and is now a active lawyer. You may say that staying young is easy only for those live in the future. In fact, you can do it whether you care enough to try to keep your mind awake and active, and which is the only way to be always young.
Friendship is very importance. Everyone needs friendship. In all our lives we can’t live without friendship just as we can’t live without air and water. Friendship makes us getting on well with one another to go ahead under different kind of difficulties in the front of us. But real friendship is no easy to come by. True friendship must be sincerely and be based on understand each other but not on benefits of each other. A good friend can always be a good teacher to us. By his advices we are persuading to go the right way. Therefore more friends we have, the better we can improve ourselves.
