关于复合宾语的被动态
我的语法书中这样写到：
含复合宾语的动词变成被动语态时,将宾语变为主语,宾语补足语变为主语补足语,但若谓语动词为listen to,feel,hear,see,look at,notice,make等而宾补不带to的不定式时,变被动应加上to.
我不大理解“但若谓语动词为listen to,feel,hear,see,look at,notice,make等而宾补不带to的不定式时,变被动应加上to.”这句话的意思,因为书中所举的例子变为被动态后并没有看到所谓的“宾补不带to的不定式时,变被动应加上to.”
所以麻烦帮我把listen to,feel,hear,see,look at,notice,make这些词变被动加to的例子一一举下,
