     I'm a college student in Shanxi Normal University now. Three years ago, I studied in a high school. (1)I

worked very hard and did well in every subject. And I took an active part in all kinds of activities with my

classmates, such as holding sports meet, planting trees, visiting some places, watching the traffic with the

policemen and contributing clothes, books, pencilboxes and money to poor villages. But I can never forget

a special activity-a visit to a blind and deaf school.

     On October 3rd, 1998, the students in our school visited the An Qing Blind and Deaf School. We had a

party with some of the disabled students there. We played games together and had a wonderful time.

     I met a girl named Zhao Yang at the party. She couldn't say a word, nor could she hear. (2)We "talked"

with each other by making some gestures and writing on each other's hand. Soon we became good friends.

When it was time to say "Good-bye", she wrote on my hand, (3)"Please come here as often as possible." I

saw her words and tears roll down my face at once. (4)Many people are concerning about (关心) disabled

people, and they give away money to assistance fund (救助基金). But the disabled people also want more

communication (交往) with ordinary people. If you know any disabled people, please don't forget to visit

them "as often as possible". They need our help.
