目的狀語(yǔ)從句是指從句部分用以補(bǔ)充說(shuō)明主句中謂語(yǔ)動(dòng)詞發(fā)生的目的的狀語(yǔ)從句??梢杂蓆hat, so that, in order that, lest, for fear that, in case等引導(dǎo)。

目的狀語(yǔ)從句的謂語(yǔ)常含有may, might, can, could, should, will, would等情態(tài)動(dòng)詞。

例如:
You must speak louder so that /in order that you can be heard by all.

He wrote the name down for fear that(lest) he should forget it.

Better takes more clothes in case the weather is cold.

引導(dǎo)目的狀語(yǔ)從句常用的連詞有:

Say it louder(so)that everyone can hear you.
大聲說(shuō),以便大家都能聽(tīng)到你。

I am telling you that lest you should make a mistake.
我告訴你這一點(diǎn),以免你搞錯(cuò)。

學(xué)習(xí)目的狀語(yǔ)從句應(yīng)注意以下:

(1)目的狀語(yǔ)從句中常含有can,could,may,might,should等情態(tài)動(dòng)詞。

I got up early so that I could catch the first bus.
我起得很早,目的是為了趕上頭班公共汽車。

(2)在口語(yǔ)中so可以引導(dǎo)目的狀語(yǔ)從句。

We'll sit nearer the front so we can hear better.
我們坐的靠前一點(diǎn),因此,我們聽(tīng)得清楚一點(diǎn)。

【注意】in order that與in order to的區(qū)別:
in order that+從句
in order to+動(dòng)詞原形 ( in order to后面加的那個(gè)不叫目的狀語(yǔ)從句,叫目的狀語(yǔ))

in order to 為了,后接動(dòng)詞原形,做目的狀語(yǔ)。
i get up early in order to catch the early bus.

in order that 為了,后接從句,做目的狀語(yǔ)。
i get up early in order that i can catch the early bus.

目的狀語(yǔ)從句的一個(gè)特點(diǎn):
由于目的都是未來(lái)的行為,所以從句中一般用表示未來(lái)可能性時(shí)態(tài),
當(dāng)然還可以用will,would,can,等
結(jié)果狀語(yǔ)從句的連詞
