探究案Ⅰ、动词不定式的形式；一般式：to do/ to be done(表示的动作通常与谓语动词所表示的动作同时发生或是在它

之后发生）I plan to attend the meeting to be held tomorrow、进行式：to be doing（不定式的动作与谓语动词所表示的动作同时发生）I am very glad to be working with you、完成式：to have done/to have been done（不定式的动作在谓语动作所表示的动作之前发生）I`m very sorry to have kept you waiting、Ⅱ、动词不定式的结构；

1、带to的动词不定式；有些动词能直接跟带to的动词不定式；如：ask,tell, hop,decide,want,forget、,stop等。

2、不带to的动词不定式；1）在feel,hear,listen

to,let,make,have, see,,look at,watch, notice、observe等使役动词和感官动词后，动词不定式作宾补时不带to。I often hear him sing the song、2）在would rather(would sooner,had rather, had sooner)----than,rather than等结构中than之后用不带to的不定式I would rather go than stay、3）在why do sth? Why not do sth结构中不带to Why not do it right now?4）在cannot but,cannot choose but,cannot help but之后的动词不定式不带to、I cannot but admire his courage、我只有佩服他的勇气。5）动词不定式在介词

but,except,besides后面是，如果这些介词之前有行为动词do的各种形式，那么这些介词后的动词不定式不带to,否则要带toShe could do nothing but cry、I have no choice but to accept the fact、6） had better 后跟省略to的不定式。You had

better go home now、Ⅲ、动词不定式在句中的作用动词不定式

在句中可以作主语、宾语、表语、宾语补足语、定语或状语。

1、作主语：①To do morning exercises is useful for

our health、②To know something about English is one thing; to know English is quite another、2、作宾语：1)及

物动词(短语)agree, want, wish, hope, refuse, manage, ask, offer, promise, pretend, decide, learn, determine, expect, beg, choose, force, intend, attempt, care, fail, hesitate, claim, long(v、), strive, plan, prepare, would like(love, prefer)等后面要求接动词不定式作宾语。①She had agreed to go and see a movie with him、②They wal ked because they couldnt afford to take a taxi、2)当动词不定式作宾语时，若

其后跟一个宾语补足语，则往往用it作形式宾语，而将真正的宾

语移至句末，以使句子重心后移，即构成句型“主语＋谓语动词

＋it＋宾补(形容词或名词)＋动词不定式(短语)＋其它成分”。

能用于这种句型中的谓语动词常见的有：think, feel, imagine, consider等。①I thought it impossible to arrive there in half an hour、②I feel it my duty to say that you are wrong、3)动词不定式一般不用作介词的宾语，但是介词(短

语)but, except, besides, instead of等后面可以接动词不定式作宾语。①The prisoner had no choice but to obey、
