[单选题]What's the end of the story?

The prisoner stole the policeman's notebook and gave it to Mr. Green in return.B． The prisoner was caught.

解析：此题是对细节信息和词汇知识的考查。其中关键词是end of the story。根据这一提示考生可从最后一段查到有关信息。通过最后两句得知逃犯偷了警察的记事本并handed to Mr．Green作为报答(in return)。A项中gave与handed属同/近义词，故为正确答案。B、C、D三项均不符合情节，所以不能入选。

[单选题]Passage FiveIn order to learn a foreign language well, it is necessary to overcome the fear of making mistakes. If the primary goal (目标) of language use is communication (交际), 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 express 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.

not used to express one's readiness to do something in the immediate future
