可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下：（1）表示同时性，即主从句的谓语动作同时发生或几乎同时发生。
其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, once （一旦……）as soon as（一……就……）, the time（当……的时刻）, the moment（当……的时刻）,by the time（到……时候为止）, next time(下次), the first time(第一次……的时候), the last time(上次……的时候)，immediately（一……就……）, instantly（一……就……）,directly （一……就……）以下关联词引起的句子中，前面常用过去完成时，后面用一般过去时hardly /scarcely…when…（刚……就……）, no sooner…than…（刚……就……）（2）表示先时或后时，即主句的谓语动作发生在从句之前或之后。
主要连词有：after（在……之后，before（在……之前）, when(=after)等。
如：After / When the children had gone to bed, she began to prepare her lessons.孩子睡觉了以后她开始备课。
（从句的动作发生在主句的动作之前，所以从句用了过去完成时）He had learned English for three years before he went to London. 他去伦敦之前已学了三年英语。

The days are short, for it is now December. 白天短了，因为已是12月了。 （四） 目的状语从句
引导目的状语从句的连词：in order that, so that（为了）；for fear that, in case, lest（以免）等。

When he returned, his wife was cooking. 他回来时，他妻子在烧饭。
While he was reading（或read）, his wife was cooking（或cooked）. 他看书时，他妻子一直烧饭。
As he was reading（或read）, he was listening(或listened) to the radio. 他边看书边听广播。
1、 because, since, as 都可表示“因为”。
（1） because 表示原因的语气最强， 通常回答以疑问词why 引导的问句，除 特别强调外，该从句一般位于主句后； since 表示稍加分析后而推断出来的原 因，比as 正式；as 表示对方已知道的原 因。since 和 as 不回答why 引导的疑问 句，而且其从句一般放在句首：
