Question

【题目】People running everywhere. Do you know what ?

A. see; has happened B. see; happens

C. are seen; is happening D. are seen; is happened

Answer 1

【答案】C

【解析】句意：到处可见人们奔跑。你知道正在发生什么事吗？结合句意，主语people与谓语see之间是被动关系，故用被动语态，故排除AB两项。happen表示“发生”，没有被动形式。根据running可知此处表示正在发生什么事，故用现在进行时be doing，故选C。
