动词不定式做宾补．
例如,He asked me to do the work with him.
在感官动词feel,hear,listen to,look at,notice,see,watch
have,make,let等词后的补足语,不定式不带to．
但是这些句子如果变成被动结构时,就必须带to．
例如,I often hear him sing the song.
He is often heard to sing the song.
动名词不能充当宾补．
现在分词和过去分词都能充当宾补,现在分词一般表示正在进行的动作,过去分词一般表示已经完成的动作．
例如,I saw him waiting at the bus.
He found his wallet stolen.
现在分词的被动也能做宾补,表示被动,正在进行的动作.
We found the flat being decorated.
