根据下面资料，回答题 Learning a Foreign Language
In order to learn a foreign language well, it is necessary to overcome fear of making mistakes. Ifthe primary goal of language use is 41 (communication) , then mistakes are 42 (second)considerations that may be dealt with gradually as 43 (aware) of those mistakes increases. Onthe other hand, students should not ignore their mistakes. The language 44 (learn) may observehow native speakers express themselves, and how native 45 (express) differ from the way thelearner might say them. For example, a Spanish speaker who has been saying "I do it" to expresswillingness to do something in the 46 (immediately) future, could, by interacting (交际) withnative speakers of English,observe that native speakers 47 (actual) say "I' 11 do it". The resulting discrepancy (差异) can serve as a 48 (basic) for the student to modify his way of usingthe 49 (presence) tense in English. But a student who is unwilling to interact in the first place
would lose this 50 (opportune) to learn by trial and error.
