Grammar
1. 原因状语从句
    从句表示的是主句行为的原因，就构成原因状语从句。一般由because引导，有时since也可以用来表示原因。
     He failed the exam because he was too careless.
     Since you have known the whole accident, I needn’t tell you anything about it.
2. 结果状语从句
    表示“由于某个原因，所以引起某件事情”，即主句表示原因，从句表示该原因产生的结果。通常由so引导。
    He worked too hard, so he fell ill again.

Grammar
3. 目的状语从句
     如果从句表示的是主句行为的目的，该从句就是目的状语从句。一般由so that 引导。
    I got up early so that I could catch the early bus.
    目的状语从句有一个特点：由于目的是将来可能会实现的，所以从句中一般用表示未来可能性的词语，如could， will，can，would等。
