Question

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

A.singB.singingC.to sing

Answer 1

【答案】C

【解析】

句意：他經(jīng)常被聽到他在房間里唱英文歌。

考查動詞不定式。sing動詞原形；singing 現(xiàn)在分詞或動名詞；to sing動詞不定式。根據(jù)He is often heard可知這里是用的一般現(xiàn)在時的被動語態(tài)，感官動詞hear在主動句中的用法為：hear sb do sth表示聽到某人做某事，變?yōu)楸粍诱Z態(tài)時其句式結(jié)構(gòu)為 be heard to do sth．此空應(yīng)填to sing，故選C。
