二重难点把握

动词不定式的用法

1.构成：to+动词原形，无人称和数的变化

2.作主语（1）位于句首，谓语动词用单数形式

Toseeistobelieve._________________

Togettherebybuswilltakeushalfanhour.

（2）用it作形式主语，把真正的主语一动词不定式置于句子后部

[t'sourdutytotakegoodcareofthechildren.

Itiseasyforus（finish）writingthecompositioninaquarter.

3.作宾语Wehopetogettherebeforedark.

拓展：跟动词不定式作宾语的常用动词有：agree>decide>expect>fail、hope>manage>offer>

plan>prepare>pretend、refuse>want、wish。

当复合宾语中的宾语是动词不定式时，先用形式宾语it代替动词不定式，把动词不定式置于

宾语补足语之后，即主语+动词+it+宾语补足语+todosth.

Wethinkitimportanttolearnaforeignlanguagewell.

4.作宾语补足语Myparentswillnotallowmetoplayonthestreet.

拓展：有的动词在主动语态中用不带to的动词不定式作宾语补足语，但在被动语态中要将to

还原。这些动词有：feel、hear^make、have>see>watch>noticeo

5.作表语Mypurposeistopointoutthedifficultiesofthematter.我的目的是指出这件事的难处。

6.作定语ThenexttraintoarriveisfromShanghai.Doyouhaveanythingtoeat?

7.作状语Icomeheretosaygood-byetoyou.（目的状语）
