to do,doing,done,作宾语补足语时有何区别？

ing与to do做宾补
现在分词通常在下列动词后作宾语补足语：see , hear , notice , watch , keep , find , get , have , feel
e.g.
·He heard someone knocking at the door .
·I”m sorry to have kept you waiting .
在see , hear , watch , notice 等动词后不定式作宾语补足语与现在分词作宾语补足语的区别：
现在分词作宾语补足语表示动作正在进行；不定式作宾补表示动作从开始到结束的全过程。
e.g.·As I drove past the park , I saw some people playing football . (= When I saw them , they were in the middle of playing .)
·Last week , I went to London and saw England play Brazil in the big football match . (= I saw the whole game .)
·I heard someone coming up the stairs .
