Question

【题目】_________ his mother tried her best to help her son with his English, he still did not pass the quiz at last.

A.BecauseB.ButC.AlthoughD.So

Answer 1

【答案】C

【解析】

句意：尽管他母亲尽力帮助儿子学英语，但他最后还是没有通过测验。

考查连词辨析。Because因为，前后句意是因果关系，引导因果状语从句；But但是，并列连词，连接并列句，前后句意是转折关系；Although虽然，引导让步状语从句，前后句意是转折关系；So所以，因此，并列连词，连接并列句，前后句意是因果关系，后面跟结果。根据句意前句是让步条件，前后句意是转折关系，故选C。
