Hello nima,
Did you check out the links I gave you in your other thread?
We have a lot of helpful people around here. And by no means is English the first language of all of our members. But I'm not sure EvC is the best place to
learn English. Unless you specify, folks here won't assume you're asking a language-use question and you're probably not gonna get the kind of help you're looking for.
I really do suggest you try the
WordReference Forums. Your questions would be answered almost instantly, and because everyone's native language and location is listed by their username, you will know which answers are most relevant to the style of English you wish to learn (American, British, Canadian, etc.).
Whatever you choose, best of luck on your language-learning adventure!
Love your enemies!
