[1] What does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.

[2] First of all , successful language learners are independent learners . They do not depend on the book or the teacher . Instead of waiting for teachers to explain , they try to find the patterns and the rules for themselves . They are good guessers who look for clues and form their own conclusions.

[3] Secondly , successful language learning is active learning . Therefore , successful learners do not wait for a chance to use the language but              . They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate . They are not afraid to repeat what they hear or to say strange things . They are willing to make mistakes and try again. When communication is difficult , they can accept information that is inexact or incomplete . It is more important for them to learn to think in the language than to know the meaning of every word.

[4] Finally ,successful language learners are learners with a purpose . They want to learn the language because they are interested in the language.

[5]What kind of language learners are you? If you are a successful language learner , you have probably been learning independently , actively and purposefully . On the other hand , if your language learning has been less than successful , you might do well to try some of the techniques above.
