从句，地点状语从句，原因，目的，结果， 条件，让步，比较和方式状语从句。
2. 时间状语从句
起时间状语作用的句子；可放在句首，句中和句尾
常用引导词：when，while, as, after, before, since, till, until, the moment, hardly … when , no
sooner … than
when, while, as 的用法
1) when 用法最广，常可代替while和as, 在while 引导的从句中，动词只能是延续性的

The telephone rang while I was taking a bath.
2) 当两个表示时间延续的动作同时发生而又有对比意味的时候，用while，在这样的复合
句中，主句从句的时态通常是相同的。
Father was preparing a report while I was playing PC games.
3) 常用as 的情况：一边…一边；表示随着短暂动作的发生，另一行为伴随发生

until和till 的用法
表示“一直到…”时，主句和从句都用肯定式；

表示“直到…才…”是，主句用否定，从句用肯定式。They can’t go until Sunday.
since的用法
He has written to me frequently since he was ill. 自从他病好以来，他常写信给我。
主将从现。时间状语从句一般不用将来时。因此如果主句是将来时，时间状语从句一般
要用现在时。
