1. 引導結果狀語從句的從屬連詞
主要的有so that, so…that, such…that等：
He studied hard so that he passed the exam. 他學習用功，所以考試通過了。
He was so angry that he couldn’t speak. 他氣得話都說不出來。
He shut the window with such force that the glass broke. 他關窗子用力很大，結果玻璃震破了。
注：so…that和such…that中的that有時(尤其在口語中)可省略：
I am so busy I have no time to write a letter. 我很忙，連寫信的時間都沒有。
There was such a lot of rain (that) we couldn’t go out. 雨那么大，我們沒法出去。
2. so…that與such…that的用法比較
從用法上看，so后應接形容詞或副詞，而such后接名詞(參見以上例句)。但有時“so+形容詞”后還可接一個名詞，且這個名詞總是帶不定冠詞的單數(shù)可數(shù)名詞(不能是復數(shù)名詞或不可數(shù)名詞)：
正：He is so clever a child that we all like him. 這小孩很聰明，我們都喜歡他。
正：They are such clever children that we all like them. 這些孩子很聰明，我們都很喜歡。
誤：They are so clever children that we all like them.
此時的so…that結構可與such…that結構轉(zhuǎn)換：
It’s such an interesting film that we all want to see it. 這電影很有趣，我們都想看。
It’s so interesting a film that we all want to see it. 這電影很有趣，我們都想看。
注：在much, many, little, few 這四個詞前總是用so而不用such：
He had so many falls that he was black and blue all over. 他摔了許多跤，結果全身都是傷。
He earns so little money that he can hardly feed his family. 他賺的錢很少幾乎不能養(yǎng)家糊口。
3. 結果狀語從句與不定式短語的轉(zhuǎn)換
由so that和so…that引導的結果狀語從句有時可與表結果的so as to和so…as to引出的不定式短語轉(zhuǎn)換：
He arrived late so that he missed the train. / He arrived late so as to miss the train. 他到得很遲，結果未趕上火車。
He wrote so carefully that he made no mistakes. / He wrote so carefully as to make no mistakes. 他寫得很仔細，所以沒有出錯。
4. so that引導目狀語和結果狀語的區(qū)別
(1)含義上的區(qū)別：引導目的狀語從句時表示的是一種意欲或可能性，引導結果從句時表示的是一種事實。
(2) 形式上的區(qū)別：引導目的從句之前不用逗號(說話時也不停頓)，而結果從句之前則通常有逗號(說話時常有停頓)；有時引導結果狀語從句時其前也可以沒有逗號，此時可看從句中是否有 can中/ could, may / might, will /would 以及should等情態(tài)動詞，如果沒有，則多半是結果從句。比較：
We’ve come early so that the meeting can begin promptly. 我們來得很早，以便可以馬上開會。(so that 引導目的狀語從句)
We are all here now, so that the meeting can begin at last. 我們現(xiàn)在都到齊了，終于能開會了。 (so that 引導結果狀語從句)
I am going to the lecture early so that I’ll get a good seat. 我想早點去聽演講，以便找個好座位。(so that 引導目的狀語從句)
I went to the lecture early so that I got a good seat. 我去聽演講去得很早，所以找個好座位。(so that 引導結果狀語從句)
另外，so that引導目的從句時有時可放在主句之前，而引導結果從句時卻不能：
正：So that he could buy a new car, he saved a lot of money. 他節(jié)省了一大筆錢，以便能買輛新車。(引導目的狀語從句)
誤：So that I could hardly stand, I was tired.(引導結果狀語從句不能置于句首，可改為I was tired so that I could hardly stand. 我很累，幾乎站不穩(wěn)了。)
5. so…that和such…that有時不引導結果狀語句
so…that和such…that可以引導結果狀語從句，但并不是說它們引導的從句就一定是結果狀語。請看以下句子：
I’m so happy that you could visit us. 我很高興你能來看望我們。(其中的so用于加強語氣，相當于very)
It’s such a great pleasure that you are here. 你在這里是非常令人高興的事。(其中的that引導的是主語從句，句首的it為形式主語)
主要的有so that, so…that, such…that等：
He studied hard so that he passed the exam. 他學習用功，所以考試通過了。
He was so angry that he couldn’t speak. 他氣得話都說不出來。
He shut the window with such force that the glass broke. 他關窗子用力很大，結果玻璃震破了。
