Question

I saw Tom _____ into the classroom without _____.

A. slide; found

B. sliding; find

C. sliding; being found

D. to slide; being found

Answer 1

C

【解析】试题分析：考动词变化形式。see sb do sth,看见某人做了某事；see sb doing sth,看见某人正在做某事；根据句意，我是看到汤姆正在某教室溜，所以是sliding；without 为介词，接名词或动名词，所以此处是-ing形式，另外因为汤姆是被发现，被动语态，without beingfound；注意类比：I saw Tom sliding into the classroom without feeling nervous.，为主动语态。句意：我看见汤姆正在往教室溜而没有被发现。故选C

考点：考查动词变化形式。
