Question

【题目】Now students in some schools ________ not to use mobile phones.

A. ask B. asked C. are asked D. were asked

Answer 1

【答案】C

【解析】

句意：现在一些学校的学生被要求不能使用手机。A. ask一般现在时的主动语态；B. asked一般过去时的主动语态；C. are asked一般现在时的被动语态；D. were asked一般过去时的被动语态。now（现在）是说当前的情况，句子不能用一般过去时来表达。故排除B和D选项；又因为学生是被要求不要去做某事，故用被动语态，被动语态的构成是be+动词的过去分词，故答案选C。
