Dear Brown,
Last summer I take a part-time job in the International Camp for children．I have told one more worker will be needed in this year and I think you are fit for it．How about join us? The camp is at the foot of a small hill closed to a river．It is such beautiful a place! We can hear birds singing happy all around．Everybody sleeps in tents, that is very exciting．We usually work only five hours a day, so we will have plenty of spare time to visit the area and have fun. I am sure it will be a unforgettable experience．If you have interests in it, write to me soon．
Yours, Mary
We often think insects to be harmless. This is partly true. Many an insect are harmful. Flies carry diseases. Others insects carry diseases, too. Farmers are at war with insects most the time. Hunger insects kill crops in the fields Farmers spray the field as to get rid of these insects. Does this means that all insects are harmful? No. Many are of great helpful to man. Bees make honey. With bees and other insects, many trees would have not fruit. Silkworms make silk. Some insects eat other insects that kill fruit trees.
One day I was dining with my friend Zhou in McDonald when two young girls came in hand in hand. While enjoyed a hamburger, I found Zhou looking around at something strangely.
I raised my eyes to see what was happening. The two girls are making gestures skillfully. Obviously they were deaf-mutes. I had learned some sign languages ago, so I showed various gestures with Zhou following me in low spirits. We played and laughed cheerfully as if there had no one else present. Suddenly we saw both the two girls glaring at us. Before we could explain to them, they had walked out angrily, left the food unfinished. They thought we were making joke of them. How I regretted!
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.
