状语从句连接词

时间状语从句：常用引导词：when, as, while, as soon as, before, after, since , till, until

特殊引导词：wherever, anywhere, everywhere

地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型:

句型1：Where＋地点从句，（there）＋主句。

【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如：

Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。

句型2：Anywhere/ wherever＋地点从句，＋主句。

【注意】anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。例如：

Wherever the sea is , you will find seamen.有海就有海员。

件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状

语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。
