2.想知道他是什么原因一直没有上线,如有困难愿意提供帮助,盼望回信.
100词左右
谢谢了,哪位高手帮帮我吧 .

Dear Michael;
How are you? First I'll thank you very much for your help in my English study. For half a year we've been on the line and talking a lot. Ever day we talk an hour or so about our studies, our countries, our hobbies and so on. With these I have made great progress in my spoken English. Again thank you very much. However, what has happened to you? I'm so sorry that you haven't been online and that I haven't seen you for nearly a month. I'm wondering if you have got some trouble. If so or you need my help, please leet me know. I'll do my best to help you.
Looking forward to receiving your letter soon.
Best wishes to you.
Yours ever.
Wind.
