【考点】书信类．

【答案】I'm glad to receive your letter，and now I'll tell you something about the first aid course in our school and some suggestions about scald.
The first aid course is a necessary part of  education in our school.If we have learned something about first aid，we could help those in danger and even save their lives in time.Here is some advice about burns are as follows：First，remove clothing using scissors if necessary unless it is stuck to the scald.Then，place the affected area under cool running water.Last but not least，you'd better go to hospital if the affected area is still painful.The course is very interesting and beneficial.
Would you like to come here to study again？We are all looking forward to it.

Yours，
Xiao Li
