Last year, I went to Beijing Qizhi Special Education School for community service (社区服务). Before we took the bus, my friend asked me a question, "Why are you here?" I did not know how to answer the question.

    The school was not far from my school, but it looked like it was in a different world. A group of children were waiting for us. A boy walked toward me. He held my hands and pulled me to the ground. I kissed the earth and tasted nature.

    I could not understand what he was doing at first, then I was very angry. Though I was very angry, I controlled my anger.

    A teacher stopped this awkward (尴尬的) silence when she shouted at the boy. "What are you doing right here, right now?" she said. "You will never see your mum again if you keep doing this. Now, say sorry!" "Sorry," he cried fearfully and nervously. I said nothing, but I realized something about this child. After lunch I asked the teacher for information about the child's parents.

    She said that the child was very different from other students because of an illness. His family could not afford to treat him. He needed the kindness of his family, but they had abandoned him. So he depended on the support from the ' teachers and community service workers like us.

    I suddenly realized I could answer the question my friend asked me at the beginning of the day.

    Community service workers help others and make everyone feel better. There are so many people in the world that need help. Playing with lonely children may not make a big difference. But it can light a corner in the children's hearts, making them know they are loved by people.

    When I was 13 years old, the doctor said that I had a kind of attention disorder. So when everyone else in the class was focusing on tasks, I couldn't.

    In my first class, Mrs Green asked us to read a story and then write on it within 45 minutes. I raised my hand right away and said, "Mrs Green, you see, I have attention problems. I might not be able to do that."

    She looked at me and said, "You are no different from your classmates, young man." I tried, but I didn't finish the reading. So I took it home.

    In my bedroom, it was so quiet and the story suddenly became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system which opened up a new world to the blind. Wasn't I the "blind" in my class, being made to learn like the "sighted (有视力的)" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others. If Louis could find his way out of his problems, why should I ever give up? I didn't expect anything when I handed in my paper to Mrs Green, so when it came back to me the next day with an "A" on it, I couldn't believe my eyes. At the bottom of the paper were these words, "See what you can do when you keep trying."

Many years ago, when I was working as a volunteer(志愿者)at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion(输血)from her five-year-old brother. The little boy had the same disease before and had developed the antibodies(抗体)to fight the illness.

    The doctor talked to me little boy about what they planned to do, and asked him if he would be willing(愿意的)to give his blood to his sister. I saw him hesitate(迟疑)for a moment. He took a deep breath and said, "Yes, I'll do it if it can save Lisa."

    As the transfusion was going on, the little boy lay quietly in bed next to his sister. He looked at her and smiled all the time. When everything was done and the color returned to his sister's face, his smile disappeared and he looked a little afraid. He looked up at the doctor and asked, "Will I start to die now?"

    He was too young to understand the doctor. He thought he would have to give all his blood to his sister, but he agreed.

There were some mice at Jack's house.They ran into the kitchen and ate food at night.In the day,they went back to their home.So it was difficult for Jack to get them.

"I need a good cat,"Jack thought.He knew Mr.Brown had a shop and there were many cats and dogs.

"I need a cat,Mr.Brown,"Jack said."The cat must be good for the mice."

"Well,I have such a cat,"answered Mr.Brown.

"I'll take it,"said Jack.He paid for the cat and went back.

A week later,Jack went back to Mr.Brown's shop with the cat."There are more mice at my house,"Jack said.He was very angry."Your cat doesn't want to catch them at all.But you said it was good for the mice."

"That's right,"said Mr.Brown."It's good for the mice.Come to think about it—it is good for the mice!"
