Unit4 语法（2）

连词 until, so that及although引导的状语从句

1. until引导时间状语从句

连词umtl意为“直到……为止;到…时”,引导时间状语从句,常放在主句之后,也可以放在主句之前。主句为一般将来时,从句要用一般现在时表示将来。umti用于肯定句中,意为“直到…为止”,主句谓语动词须用延续性动词;用于否定句中,意为“直到……才…”,主句谓语动词通常用非延续性动词,也可用延续性动词。

She often works in the field until it gets dark.

她经常在田里干活到天黑。

We didn' t go home until the rain stopped.

直到雨停了,我们才回家。

I won't believe it until I see it with my own eyes.

直到亲眼看见,我才会相信。

2. so that导目的状语从句和结果状语从句

（1）so that意为“以便”,引导目的状语从句时,一般放在主句后,且不用逗号隔开。目的状语从句表示动机(即一种可能性),而非事实。因此,从句中常带有can,will, could，would, shoud等情态动词。

I got up early so that I could catch the early bus.

我起得早,以便能赶上早班公共汽车。

You must go now so that you won't be late.

你必须现在就去,以便不会迟到。

(2) so that为“以至于;结果”,引导结果状语

从句,陈述的是客观事实,常常不带情态动词。

He studied hard so that he pass the exam.

他努力学习,结果通过了考试。

3. although引导让步状语从句

连词 although意为“虽然;尽管;即使”,引导让步状语从句,可以放在主句前面,也可以放在主句后面。

Although you are tall, I'm not afraid of you.

尽管你个子高,但我不怕你。

You could help him although you didn't let him copy your homework.

尽管你不让他抄你的家庭作业,但你可以帮助他。

eg:(1)——Shall we go now?

——No. let's wait___ the rain stops.

A. until

B. when

C. if

D. as

解析:我们可用“语境分析法”解答本题。until意为“直到……为止”;when意为“当……时候”;if 为“如果;是否”;as意为“当……时”。结合空格所在句句意“不，让我们等着___ 雨停”可知A项符合题意。

答案:A

A. because

B when

C. so that

D. as if

解析:我们可用“语法分析法”解答本题。because。因为”用于引导原因状语从句;when“当…的候”,用于引导时间状语从句；so that“以便;结果”,用于引导目的状语从句和结果状语从

句;as if“好像;似乎”。后半句“他能更多地了解中国”是前半句“我要带他去一些有名的胡同”的目的,故选C。
