谁来帮我检查一下这篇作文有什么错吗?
是篇回信
Dear sally,
I'm sorry to hear that you're not felling very well.I think you shoule have a rest.You are streessed out too big,so you have a lot headaches.I think you can listen to music.And going to bed is good for you.As for your Putonghua,I think you should listen to Chinese songs and read Chinese books.Of course,talk to your Chinese classmates is also good for this!
I hope you feel better soon!
yours
