一、结果状语从句的定义：在句子中作结果状语的句子称为结果状语从句。常用的引导词有: so/such...that...”如此……以至于……“；so that ”结果是“。
二、结果状语从句的用法：
（一） so that：引导结果状语从句，表示“因此，以至于”，此句中大多不用情态动词。
例如: I got up early, so that l caught the first bus.我早早就起床了，结果赶上了首班车。
（二）so...that...表示“如此……，以至于……”，so后面接形容词或副词。
1、so+形容词+that       
例如：①He was so ill that two nurses attended on him.他病得那样重，有两个护士照顾他。
②The room was so hot that she felt dizzy.房间里如此之热,以至于她觉得头晕目眩。
2、so+副词+that    
例如：①He spoke so clearly that l could hear every word.他讲得非常清楚，每个字我都听得见。
②They sat so close that their heads nearly touched.他们坐得那么近，头都差不多碰到一起了。
（三）such...that...
与so...that.不同的是，such...that...中的such后接的是名词。其常见的结构用法有：
1、such+不定冠词+形容词+单数可数名词+that     
例如：①He's such a good swimmer that he makes me look sick. 他游得这么好，真叫我相形见绌。
②Her husband is such a bear that nobody likes him.她丈夫夫很粗暴，没人喜欢他。
此时，such...that...可以用so...that...来替换，其结构为: so+形容词+不定冠词+名词+that。如以上第一句话就可以改为:He's so good a swimmer that he makes me look sick.
但是，如果该名词没有被形容词修饰，则不可以改为so...that....。如上面的第二句就不可以改。以下第2和第3种情况也不能改为so...that...的用法。
2、such+形容词+复数可数名词+that   
例如：He told us such funny stories that we all laughed. 他对我们讲了那么些有趣的故事，我们全都哈哈大笑。
3、such+形容词+不可数名词+that       
例如：It is such terrible weather that it is absurd to go out.在这么恶劣的天气里出去太荒唐。
（四）so many/much/few/little...that....
so与表示数量的代词many、few、much、little等连用是常见固定搭配，不能换用such的对应结构。
1、so+manylfew (+复数名词) +that
many/few有时作定语，后接复数名词，但有时直接用作表语，后面不再接其他成分。
例如:①They asked so many questions that they confused me. 他们问了许许多多问题，把我弄糊涂了。
②The butterflies are so many that they often cover entire trees .蝴蝶数量多的时候，它们经常会遍布整片树林。
③He has so few friends that his life is lonely. 他的朋友很少，因此他的生活非常孤单。
2、so+much/little (+不可数名词)+that
与manylfew一样,much/little有时作定语，后接不可数名词，但有时直接用作表语，后面不再接其他成分。
例如:①She wore so much jewellery that she seemed to be covered in gold. 她戴了那么多首饰，看上去象是包在金子里似的。
②He talk so much that no one else can get a word in edgeways. 他讲得滔滔不绝，别人都无法插嘴。
③There is so little time left that l don't think l can finish it as scheduled. 剩下这么少的时间，我想我不能按时完成。
④The box costs so little that l can afford it. 这个箱子很便宜，我买得起。
（五）that      
that也可以直接用来连接结果状语从句。
例如: What have we done that you should be so angry with us? 我们做了什么使你这么生气?
