Dear David,
Last week we held a discussion on what we should do for our school before we graduate(毕业). The students in our class have different suggestions.
                                                                     
                                                                     
                                                                     
                                                                     
                                                                     
                                                                     
                                                                     
I’d like to know your idea. Could you give me some advice?
Best wishes,
Li Ming
