     English is one of the most popular languages in the world. It comes second in the number of speakers after Chinese. In Vietnam, more and more people are studying English and they consider it a key to success. However, not everyone knows how to learn English effectively.

     The best way to improve the four skills: speaking. Irstervng, reading, and writing is to practice regularly. You should make use of every opportunity to speak English with friends in class or at English-speaking clubs or ourselves in front of the mirror. Learning by heart all the words does not help much if you do not read a lot because you will easily forget what you have learnt. Reading books, listening to radio, and watching films are better ways to memorize words. Practicing speaking English a lot is a good way to correct your mistakes. Why don't you try the advice to see how helpful they are to you.
