结果状语从句
【课程导入】
1. 能够理解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。
2. 结果状语从句引导词有: so...that...,such...that...,so that
【语法学习】
【考点】
so...that...,such...that...等引导的结果状语从句。
【知识点】
1. so…that…
(1)so…that…引导结果状语从句,表示"如此……以致……"。
连词so...that...的用法
1、接形容词
The wind was so strong that he could hardly move forward. 风刮的如此猛烈,以致他几乎是寸步难行。
2、接副词
He runs so quickly that none of us can catch up with him. 他跑得那么快,我们谁也赶不上他。
3、接分词
We are so accustomed to adopting a mask before others that we end by being unable to recognize ourselves. 我们大家都如此习惯于在别人面前戴着面具,结果最终迷失了自己。
(2))在结果状语从句中,主句和从句的主语一致的情况下,可省去从句的主语,从句谓语变非谓语。这时,前面的so就要换一个形式来陈述。
①so是中性程度副词,如果从句是肯定句,那么so就要换为enough。要注意的是:enough只能在所修饰词的后面。
He is so old that he can go to school alone.省略式为:He is old enough to go to school alone.
② 如果从句是否定句,那么so就要换成too。

2. so that
(1) so that可以引导目的状语从句,意为“以便,为的是”, 也可以引导结果状语从句,意为“以致,因此”。
(2)so that引导目的状语从句和结果状语从句的区别:一是若so that引导结果状语从句,往往会有逗号将主句与从句隔开;二是在结果状语从句中往往没有情态动词,而目的状语从句通常都含有情态动词。
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.

(2)such+a/an+形容词+名=so+形容词+a/an+名
(3)a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配。
