4、有些动词后接不定式或名词时，意思不同。如：1）remember doing sth、记得作过某事（某事已做过） remember to so sth、记住去做某事（某事还没做）2）forget doing sth、忘了作过某事（某事已做过） forget to do sth、忘了去做某事（某事还没做）3）try to do sth、=do one’s best to do sth、尽力去做某事 try doing sth、尝试做某事4）stop doing sth、停止做某事（停止正在做的事） stop to do sth、停下来做某事（停止的事去做另外的事）5）go on doing sth、继续做某事（同一件事） go on to do sth、接着去做某事（不同的事）

6、help 后的不定式可带to, 也可不带toThe teachers helped the students (to) learn English well、那些老师帮助学生学好英语。He often helps his mother (to)

tidy up the room、他经常帮助他妈妈整理房间。

7、动词不定式省to的情况一感feel 二听 hear, listen to +sb、 do sth、三使have, let, make 四看see, watch,

look at, notice常考短语：hear/see/ make / let sb、 do sth、被动语态：Sb、 be heard/ seen/made/let to do sth、（变成被动语态时补回to） I often see him help others、 He is often seen to help other by me、

二、动词不定式的句式：

1、、动词不定式作主语，主语较长时，常用it作形式主

语，而将真正的主语放在句。I t + is/was+adj、+(for sb、) + to do sth、 To learn English well is useful、 =

It’s useful to learn English well、学好英语是有用的。To protect environment is important for us、= It’s

important for us to protect environment、对于我们来说保

护环境是很重要的。

2、 It is / was + adj、(kind / good/ nice/ clever)

+ of sb、 +to do sth、It’s very kind of you to help me、 =You are very kind to help me你帮助我真是太好啦。I t’s very clever of you to do like that、=You are clever to do like that你那样做真的太聪明啦。这个句型的形容词为表示人的品格，气质之类的词。可以等于句型：sb、 is / was + adj、 +to do sth、3、 It takes ( took , will take )
