mistakes. If the primary goal (目標(biāo)) of language use is communication (交際) , then mistakes are secondary considerations that may be dealt with gradually. On the other hand, students should not ignore their mistakes. The language learner may observe how native speakers express themselves, and how native expressions differ from the way the learner might say them. For example, a Spanish speaker who has been saying "I do it" to ex press willingness to do something in the immediate future, could, by communicating with native speakers of English, observe that native speakers actually say "I'll do it". The result can serve as a basis for the student to change his way of using the present tense in English. But a student who is unwilling to communicate in the first place would lose this opportunity to, learn by trial and error.
