阅读下面短文, 请根据短文后的要求进行答题。(请注意问题后的字数要求)

[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.
