Some students thought that they can learn English well if they remember the grammar rules and learn by hearts as much words as they can. And I don’t quite agree with them. Learning rules from a grammar book and remember long lists of words are not enough. We must learn by                 

listening to, speaking, reading and writing. We should practice our spoken English both in and out class, and try to read and listen whenever possible. This is also helpful to keep diaries and write letters or shortly stories in English. Only with this way can we learn English well.
