题目内容
7.In classes,you'd better understand as much as possible while ______ notes.( )A. | take | B. | taken | C. | taking | D. | to take |
分析 在课堂上,当你做笔记的时候,最好尽可能多地理解老师讲的内容.
解答 答案:C
while引导的时间状语从句,当从句和主句的主语一致时,且从句含有be动词时,从句的主语和be动词可以省略,本句属于这种情况,while后省略了you are,因为take与you是主动关系,所以用现在分词形式,故选C.
点评 本题考查现在分词和时间状语从句的省略.当动词与句子主语构成主动关系,用现在分词的形式;如果二者构成被动关系,则用过去分词的形式.
