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。
I’ll speak slowly so that you can understand me.（目的）
He spoke slowly so that I understood him.（结果）
He always studies so hard that he may make great progress.
He always studied so hard that he made great progress.
I opened the window so that fresh air might come in.（目的）
I opened the window so that fresh air came in.（结果）
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.
=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.
Please speak up in order that/so that we may hear you clearly.
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。
（such 和so 后面所真正修饰的词是名词weather，而非形容词
（so 修饰honest; such, an 和 honest 都是修饰 boy 的形容词）
（such 和so 后面真正修饰的词是pictures，所以不可用so）
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.
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.

=He was so kind as to help me.
