动词不定式做状语时表示目的和结果的用法

动词不定式做状语时表示目的和结果用法总结

1.作目的状语:

I came here to see you.

To stop the train, pull the lever downwards.

目的状语还可以用如下表达法:

肯定:

to

in order to + 动词原形

so as to

I come to see her. = I come in order to see her. = I come so as to see her.

that

so that + 主语+ may/might + 动词原形

in order that

I come that I may see her. = I come in order that I may see her. = I come so that I may see her.

否定:

not to

in order not to + 动词原形

so as not to

that

so that + 主语+ may/might + not + 动词原形

in order that

He went away not to see me.

= He went away in order not to see me.

= He went away so as not to see me.

= He went away in order that he might not see me.

= He went away that he might not see me.

= He went away so that he might not see me.

in order to, in order that和so as to, so that的区别

in order to可以用在句首或句末,但so as to只能用在句末。如:

He got up very early in order to/so as to catch the first bus.

In order to catch the first bus, he got up very early.(此时不能用so as to)

so as to 和in order to的汉语意思应该是一样的“为的是,为了”。它们的英语功能也是一样的,都可以用来引导目的状语。它们的不同之处就在于so as to 不能用于句子的开头,在句子开头只能用in order to.

另外,

1.in order to 一般用in order that加从句来替换;而so as to 一般用so that加从句来替换。in order that 可

以在句首,so that和so as to 一样不能在句首。

2.当这两个短语后的不定式动词的逻辑主语和句子的主语一致时,“in order to , so as to +不定式”可以简化

为“不定式”
