语法归纳】

动词不定式

一、作主语

为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置。

常用句型:

It +be+adj./n.+(for/of sb.) to do sth.

It takes sb. some time to do sth.

二、作宾语

动词agree (同意);offer (提出);intend, plan (打算,计划);demand, ask (要求);promise (答应);help (帮忙);prepare (准备);decide (决定);refuse (拒绝);dare (敢于);choose (选择);wish,hope,want, expect (希望,想要);fail ;(不能;忘记);pretend (假装);manage (设法);determine (决心)常接动词不定式作宾语。

【记忆口诀】

同意提出做计划, 要求答应来帮忙。

准备决定遭拒绝, 敢于选择有希望。

不能做到莫假装, 设法做成决心强。

三、作(后置)定语

“have/has+sth.+to do”或“enough+名+to do” “It’s time to do sth.” 等结构。

四、动词不定式作状语

主要用来修饰动词,表示目的,结果或原因。

为了强调目的,有时可以把动词不定式放在句首,或在不定式前加in order (to) 或so as (to) “为了,目的是”。

常用结构有too + adj./adv. + to do sth.等。

五、作宾语补足语

tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,

构成tell/ask/want /call/invite sb. to do sth.结构。

【注意】动词不定式作使役动词和感官动词的宾语补足语时应省去to:

“一感(feel),二听(listen to, hear),三让(let, make, have,,

四看(look at, see, watch, notice),半帮助(help)”。

六、固定句式中动词不定式的用法 常见的形式有:

had better (not) do sth.最好(不)做…

Would you like to do sth.?你想做…?

Why not do sth.?    为什么不做…?

Would you please (not) do sth.?请你(不)做….好吗?
