结果状语从句由连词( so )that, so…that, such…that, so much/many…that引导。
1. so…that 如此…以至于
   The scientist’s report was so instructive that we were all very excited.
   He always studied so hard that he made great progress.
2. such…that 如此。。。以至
   It’s such nice weather that all of us want to go to the park.
3. 比较：so和 such
   其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little(这四个形容词表多或表少时)连用，形成固定搭配。
so foolish　such a fool　
so nice a flower　such a nice flower　
so much / little money such rapid progress　
so many people　such a lot of people　
（so many已成固定搭配，a lot of虽相当于many，但a lot of为名词性的，只能用such搭配。）
so…that与such…that之间的转换既为 so与such之间的转换。
The boy is so young that he can’t go to school.
He is such a young boy that he can’t go to school
难点
so +形容词或副词
so +形+a(an)+单数可数名词
so +many 或few+复数可数名词 +that
so +much或 little+不可数名词
    so that ,such…that 都可以in order that两者皆可引导目的状语从句和结果状语从句， 当他们引导目的状语从句时，从句的谓语里常常有can, could, may, might, will, would等次。
    so +adj或adv.+ that， such +n.+ that 以上两种句型都表示结果,其中so为副词,后接形容词，副词原型，当可数名词前有many, few；不可数名词前有much, little修饰时，应采用句型：so many (few, much, little )+n. 。 such为形容词, 后只能接名词。这名词既可以地可数的，也可以是不可数的。如果这名词是可数,单数,则必须在名词前加冠词a(an). 常见的形式是:

such a (beautiful)garden, such(nice)people.
It is such nice weather that I’d like to take a walk.
The weather is so nice that I’d like to take a walk.
