常用来引导结果状语的引导词或短语有：so、so that、so...that...、such that、such...that...、that等。结果状语从句的从句部分是补充说明主句中谓语动词发生的结果的，通常位于主句之后。结果从句中通常不用情态助动词，但must，can，could除外。such用在（形容词）名词之前；而so要用在形容词/副词之前，so或that有时会省略掉。
1.so that可以引导目的状语从句，也可以引导结果状语从句。
例如：
He worried so that he couldn’t sleep。
他急得睡不着。(so that引导结果状语从句)
It was very cold,so that the river froze。
天气寒冷，河水都结冰了。(so that引导结果状语从句)
I came to the class early so that I could see the classmate beside me。
我赶早来上课，以便早点看到我旁边的同学。(so that引导目的状语从句)

风刮得如此猛烈，以致他几乎是寸步难行。

so+many/few（+复数名词）+that

他给我的时间如此少，要我按时完成任务是不可能的。
2.表示“如此……以致……”的“so...that...”和“such...that...”均可引导结果状语从句，其中的such是形容词，修饰名词；so是副词，修饰形容词或副词，具体的搭配形式是：
(1)“so+adj./adv.+that”，“so+adj.(+a/an)+n.+that”；
(2)“such(+a/an)(+adj.)+n.+that”。
例如：
He speaks so fast that no one can catch him。
他说话太快，无人听得明白。
There is so rapid an increase in population that a food shortage is caused。
人口增长如此迅速，以致造成了粮食短缺。
Our country has so much coal that she can export large quantities。
我们国家的煤炭非常丰富，可以大量出口。
(so与表示数量的代词many，few，much，little等连用已经形成固定搭配，这些场合下不能换用such的对应结构表示)

这家商店出售的货物价格昂贵，以致我在里面不想购买任何东西。

They are such fine teachers that we all hold them in great respect。
他们是非常好的老师，我们对他们极为尊敬。
It is such nice weather that I would like to go to the beac。
天气如此之好，我想去海滩。
如果结果状语从句的主语与主句的主语相同，可用so(adj/adv)as to取代该结果状语从句，注意体会以下例句：
The weather was bad,so as to make a good photo hard to take。
天气恶劣，以致难以拍出来好照片。
He was so kind as to phone for a taxi for the patient。
他是如此热心，以至于他为病人打电话叫了出租车。
How could you be so stupid as to believe him?
你怎么这么笨，竟相信了他的话？
在结果状语从句主从句主语一致的情况下，可省去从句主语，从句谓语变非谓语。这时，前面的so...就要换一个形式来陈述。so是中性程度副词，如果从句是肯定句，那么so就要换为enough。如果从句是否定句，那么so就要换成too。要注意的是：enough只能在所修饰词的后面。例：
He is so old that he can go to school alone。省略式为：He is old enough to go to school alone。
