回复：读的不错。 不过， 我来挑点刺吧。

thank you. sound you suggested appreas as numbers, no matter though, I can go to check pronunciation on dictionary.

it is very helpful while I have deaf ears to my own reading. Please point out more, if you have time.

I will try to read again, based on Mr. Ren and your comments. have a good day.

a question, I have difficult time know when it should read as s or z. do you have any general guidance on that? I remember someone posted a good article. I read but forgot to save.
