对……补充：a supplement to…
Ladies and gentlemen,
Welcome to our English Corner. This Corner was set up three years ago. Every Sunday morning, students from different schools gathered around here. Many college students and some foreigners often join us, We practice spoken English by talking about everything we are interested in. We also exchange our experience in English study. We all have a good time here. Thousands of people have been here since it was set up.
We think that we have learned a lot by taking part in activities here. It is a real supplement to our English class and it is welcomed by students. Their parents and teachers. They all think it is helpful. If you want to know more about the corner, you may talk to the students here.
Last year I bought a refrigerator in your store on Chang An road. We all like the shape and colour of the refrigerator. But recently I find something is wrong with it. It begins to make noise when it is turned on. At first it is low but gradually it becomes louder and louder. To make the matter worse, it even stops working sometimes. We all feel disappointed with. I am writing to you to ask for help. Would you please send somebody to repair it. I will be at home this weekend. Please call me before you come. My telephone number is 6606.5531. Thank you very much.
Attention please, everyone：
About twenty Japanese students will come to our school for a visit on September 15th. We'll meet at the school gate at 8：45 a.m., and give them a warm welcome when they arrive at 9：00. Then we'll take them to the reception room. After a get-together there, we'll show around the school, the library, the labs and the school factory, At 11：30 we'll have lunch with the Japanese students in the dining-hall, and then give the presents each other. The Japanese students will leave at about 12：00. That's all. Thank you.文章来自www.aiwenbi.com
