【经典考例】—Jack,your room is dirty. It should ______ right away.
—Sorry,I'll do it right now.
A.be cleaned
B.be cleaning
C.cleaned
D.is cleaned

A
解析：考查被动语态。房间与打扫是被动关系，应用被动语态；含情态动词should的被动语态结构为“should + be + 过去分词”，clean的过去分词是cleaned，所以选A。

【经典考例】The dictionary of this library may ______ for three weeks.
A.keep
B.be kept
C.borrow
D.be borrowed

B
【解析】考查被动语态的用法和动词辨析。句意为：“这座图书馆的这本字典可以借三周。”keep 是一个延续性动词,表示占有、具有、保存,borrow 只是表示瞬间动作,本句里的时间是三个星期,应该是与延续性的动词连用,所以确定用动词 keep；又因为字典与借是被动关系,所以用被动语态。may 是情态动词,其被动句式结构为“情态动词(may)+ be + 过去分词(kept)”。故选择 B。
