Hi! I'm not a teacher.
(1)Why no one answer my post ???
Here's the answer from Moderator RonBee.
http://www.usingenglish.com/forum/as...e-patient.htmlThere are many posts on this forum every day. Please be patient when waiting for a response to your question. It is difficult for one person to keep up with all the questions. (Indeed!) It is difficult for several people to keep up with all the questions. You might not get an immediate response. You might have to wait a while. So please be patient.
If you do get impatient waiting for an answer to your question, try sending someone a PM (private message) asking that person to respond to your post. (You might want to send more than one (to more than one person).)
(2) Teachers and formum members will be happy to help you with your English questions. But it would be better if you could try to do it first because the forum doesn't encourage to do homework or paper for members. And on the other hand, if you try to do it by yourself, you will improve English quicker.
