怎么区分状语从句？
要区分状语从句，首先认识什么是状语。
说明谓语动词发生的时间，地点，原因，方式，程度，频度，目的，条件，比较，让步等的就是“状语”。
做状语的有副词，词组和从句。
The girl often writes homework very carefully.（做状语有：often频度，carefully方式，very程度）My brother can't come to school because of his illness.（介词短语做状语：to school地点状语，because of his illness 原因状语）In order to catch the early bus, we'd better get up early tomorrow morning.（不定式短语做目的状语）Coming home, he found his house robbed.（现在分词短语做状语）“引导词➕主语➕谓语”构成的叫“从句”如果引导词是下列单词（词组），就是状语从句：when if where before after as than“as soon as”“so that”“in order that”“the time”“the moment”“the minute”“by the time”whatever however whenever状语从句When we got to the station,the train had left.After we had finished homework, we went to sleep.The time the mother left, her baby began to cry.妈妈一离开，婴儿就开始哭了。
We got up early in order that we can arrive at school in time.Where you go, I'll follow you.不管你去哪里，我都跟着你。
Please put your bag where you can find it.请把你的包放在你可以找到的地方。
My brother is tall as I am.However you teach students, you are excellent.不管你怎么教学生，你都是非常优秀。
