      假如你叫张霖,暑假后就要进入高中 (senior middle school) 学习。由于住校 (live at school)

等几个方面。

      注意:

      3、开头和结尾已经给出,不记入总数。

Dear Bill,

      How is everything going? Something is troubling me very much. So I'm writing to ask for your

advice. 

                                                                                                                                            

                                                                                                                                            

                                                                                                                                            

      It's so hard for me to make a decision. I'll be very glad if you could give me some suggestions.

      Please write back soon.
