非谓语动词句型问题⒈She is often heard to sing in the next r

1.这牵涉到一个常见的英语语法现象.2.如果在“使役动词(make/let/have)/感官动词 + 宾语(sb/sth) + 宾语补足语”结构中,如果使用不定式去做宾语补足语时,其在主动句中必须使用不带to的不定式,即动词原形结构.如：I often hear her sing in the next room.The school made the students clean the street.3.但是楼主需要知道并谨记的是：该结构在被动句中使用时,必须把省略的不定式to补回.所以上述两个例子变成被动语态时,则须变成：She is often heard to sing in the next room (by me).The students were made to clean the street (by the school).4.这种语法现象只限制于不定式做宾语补足语的时候,如果是现在分词/过去分词做宾语补足语,则不能这样变化.5.楼主只需要记住这个规定即可.英语语法这东西毕竟是舶来品,我们中国人非要去用语法解释清楚未免有点自圆其说.======以下答案可供参考======供参考答案1:be heard to do sthbe made to do sth
