The child, who was believed _______ by a tiger, was found in a forest.

A．to be killed

B．having killed

C．to have been killed

D．to be killing

答案

C

解析

试题分析：考查非谓语动词。“sb. /sth. +be+believed+to do”表示“某人/某物被认为„„”，动词不定式用一般式，表示其动作发生在谓语动作之后，如若用完成式，则表示发生在谓语动作之前，若用动词不定式的被动式，则表示与句子主语之间是逻辑上的被动关系。句意：据说已经被老虎吃了的孩子，在森林里面被找到了。选C。
点评：句型“sb. /sth. +be+believed+to do”可转化成It’s believed that. . . 句型。有此类似用法的词还有consider，know，say, report，suppose等。还要注意不定式后面的形式。
