【题目】Look at the rules on the wall! The books are not allowed _____ out of the room. So you had better look through it quickly in the library.
A. being taken B. taking
C. to be taken D. to take
在线课程【答案】C
【解析】
考查非谓语动词。句意：看墙上的规定！不允许将书带出房间。因此你最好在图书馆快速看完它。该句为allow的搭配be allowed to do sth。另外，take与books属于动宾关系，因而用被动，综合起来，故选C。
