Question

【题目】He is often heard________ English songs in his room.

A.singB.singingC.to sing

Answer 1

【答案】C

【解析】

句意：他经常被听到他在房间里唱英文歌。

考查动词不定式。sing动词原形；singing 现在分词或动名词；to sing动词不定式。根据He is often heard可知这里是用的一般现在时的被动语态，感官动词hear在主动句中的用法为：hear sb do sth表示听到某人做某事，变为被动语态时其句式结构为 be heard to do sth．此空应填to sing，故选C。
