状语从句运用
下面是推荐给大家的高考英语语法状语从句运用，一起来看看吧。
原因状语从句
比较：because， since， as和for
1)because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since.
I didn‘t go， because I was afraid.
Since /As the weather is so bad， we have to delay our journey.
2)由because引导的从句如果放在句末，且前面有逗
号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for.
He is absent today， because / for he is ill.
He must be ill， for he is absent today.
结果状语从句
结果状语从句常由so… that 或 such…that引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。
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连用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
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
目的状语从句
表示目的状语的从句可以由that， so that， in order that， lest， for fear that， in
case等词引导，例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
