动词不定式作目的状语

1.动词不定式作目的状语主要用来修饰动词，表示某一动作或状态的目的。为了使目的意义更加清楚或表

示强调意义时，还可以在动词前面加inorderto或soasto,意为“为了，目的是”。如：

Hestoppedtoasktheway.他停下来问路。

Iwillsitinthefrontinordertohearmoreclearly.为了听得更清楚，我要坐在前面。

2.动词不定式的否定形式是在to前加not。如：

Iwroteitdowninordernottoforget.为了不忘记，我把它写了下来。

3.由inordert。引导的目的状语，既可以置于句首，也可以置于句尾，而由soasto引导的目的状语，只

能置于句尾，不能置于句首。如：

Theystartedearlyinorderto/soastogetthereintime.

Inordertogetthereintime,theystartedearly.

Wedoafter-schoolactivitieseverydayinordertokeephealthy.

=Inordertokeephealthywedoafter-schoolactivitieseveryday.

4.动词不定式的复合结构作目的状语

当不定式有自己的主语时，要用不定式的复合结构（即在不定式前加for+.g词或代词宾格）作状语。如：

Heopenedthedoorforthechildrentocomein.

为了让孩子们进来，他打开了门。

动词不定式作宾语补足语

我们可以用动词不定式来说明宾语的情况，此时动词不定式在句中作宾语补足语。动词不定式作宾语补足

语，有带to和不带to两种形式。
