结果状语从句由连词 (so)that, so……that, such……that, somuch/many……that 引导。
1 so that; so……that
可引导目的状语从句和结果状语从句，请注意其区别。当它们引导目的状语从句时，从句的谓语里常有can, could, may,might, will, would 等词。
而当引导结果状语从句时则没有上述这些词，而且从内容上看主句和它们引起的结果状语从句有因果关系，主句为因，从句为果。

2 in order that:为了…………
in order that 和so that; so……that 表示目的时一样，从句的 谓语动词里常有can, could, may might, will, would 等词，它和不定式in order to; so as to;和to……表示目的时意思是一样的，只不过不定式表示目的时，句子是简单句。He raised his hand high in order that/so that he might be seen.
=He raised his hand so high that he might be seen.
还可以用以下的简单句（不定式表达）：
=He raised his hand so as to be seen.
=In order to be seen he raised his hand high.
=He raised his hand high in order to be seen.
=To be seen he raised his hand high.
=He raised his hand high to be seen.
他把手举高以便于别人能看见他。
Please speak up in order that/so that we may hear you clearly.
请你声音大一点，以便我们都能听清楚。
注意
so as to 只能放在后面，不能放在句首。
3 so……that/such……that 如此…………以至
so 为副词，后面可接形容词或副词；such 为形容词，后 面只能接名词。
天气那么好，我们大家都想去公园玩。
（such 和so 后面所真正修饰的词是名词weather，而非形容词
nice，所以不可用so）
多么好的天气啊，我们大家都想去公园玩。
（so 修饰honest; such, an 和 honest 都是修饰 boy 的形容词）
他是如此的诚实，以至老师们都非常喜欢他。
（such 和so 后面真正修饰的词是pictures，所以不可用so）
它们是那么漂亮的画，以至于我想把它们全买了。
注意
不可以用so……that 代替
句型：such + a(an)+形容词+单数可数名词+that
=so + 形容词+a(an)+单数可数名词+that
Mike is such an honest worker that we all believe him.
=Mike is so honest a worker that we all believe him.
迈克是如此诚实的一位工人，以至于大家都相信他。
1 ． 当可数名词前有many, few; 不可数名词前有 much,little 修饰时
句型：so many(few, much, little)+名词+that
因为此时so（副词）修饰many, few, much, little,而不修饰名词。
I have had so many falls that I am black and blue all over.
我摔了许多跤，以至于我浑身青一块，紫一块。

2．so……that:表示结果，也可以用简单句（不定式）来表示

=He was so kind as to help me.
他人很好，所以帮助我。
