英语书面表达(80词)

Dear Bob,

So nice to write to you. How about your study? Last time you've told me you have some difficulties with your math.Now, I think you would solved it well. My study is going well, excepy my English. I have some problems with my Spoken English and writing. I'm afraid to speak English with the others. I am trying to remember more words. But it seems useless. And I still have a big problem with my writing. It's hard for me to write a good composition. May you help me? Would you mind to tell me your experience of studying English? I know your English is very good. Thanks in advance for your kindness and help.

Best Regards,
Lynn
