1．在cannot but, do nothing but (except), had better, had best, rather than, would rather…than和would sooner than等结构后要求不带to的动词不定式。例如：
I have done nothing except do what I should.
2．要求动词＋-ing（短语）作宾语补足语的动词有：discover, feel, find, have, hear, keep, leave, like, need, notice, observe, report, see, smell, spot, want, watch等。例如：
Male secretaries sometimes find themselves mistaken for higher status professionals.
You can have your tape recorder repaired in the shop over there.
3．其中在see, hear, feel, observe, watch, notice等动词后，既可以用不定式作宾语补足语，也可以用动词＋-ing作宾语补足语。前者强调动作发生的事实（即动作全部过程结束），后者则强调动作的进行过程（即动作正在进行）。例如：
Tom saw his parents get into the car and drive off.
I saw him making the experiment.
注：如果是过去分词作宾语补足语，则表示过去分词所表示的动作在谓语动词所表示的动作发生之前已经完成。例如：
We found the work completely done.
