As you know there are a lot of articles on the Internet for learners and teachers of ESL/EFL. It would be a good idea for us to share information about them to improve our knowledge. I've gleaned some very helpful articles for both learners and teachers of ESL/EFL that many users of this site may be interested in.
In particular I discovered and I am especially interested in articles on learning and teaching English grammar, on second language acquisition, on the role and impact of one's native language when learning and using ESL/EFL, on the issue of translation in learning and practising ESL/EFL, on learning and practising various aspects of English, on development of four language skills (listening comprehension, speaking, reading and writing), on valuable ESL/EFL resources, tips and advice.
