一、作主语
• （1）动词不定式作主语时，谓语动词用单数。 To do morning exercises is useful for our health. 做早操有利于我们的健康。
• （2）如果动词不定式太长，常常用 it 作形式主语， 而将真正的主语——动词不定式后置。
It took me half an hour to walk there．
3
（2）动词不定式做宾语，可此宾语后还有宾语补足语的，通常要 用 it 作形式宾语，而将真正的宾语——动词不定式后置。（前 页中无宾补）例如： • • we think it important to obey the laws. √ we think to obey the laws important. ×
（3）不定式作介词宾语 • 当介词but、except、besides前面有行为动词do及其各种形式 时，介词后面的不定式可以省略to，否则不省略。 What do（助动词不算） you like to do besides play football？ We have no choice but to wait. The boy has him own idea of how to finish it.
（区别以下例子） consider doing (只有宾语） expect to do (只有宾语） want to do wish to do (只有宾语） （只有宾语）
区别 I go to see my teacher(目的状语）.
总之： 能带不定式作宾语或宾补的动词，只是一些固定的动词（再把以上两页复习）。 因为其他动词的意思不一样，虽有时形式是一样，但分析句子成分是，就不一样 了，常是动+宾.+to do/doing作定语；或动词+to do作目的/结果状语。 6 技巧：即把特殊的几个动词记住即可，有时若觉分析句子成分很难，但知道怎么
