★ 使用状语从句时要注意的几个问题。
1、注意时态替代
we’ll go outing if it doesn’t rain tomorrow. i’ll write to you as soon as i get to shanghai.
2、注意省略现象。
as (he was) a young man, he was a storekeeper and later a postmaster.
if (it is) necessary i’ll explain to you again.
3、注意区分不同从句。如：以where为例，能引导多种从句。
you are to find it where you left it.（地点状语从句）
tell me the address where he lives.（定语从句，句中有先行词）
i don’t know where he came from.（宾语从句）
where he has gone is not known yet.（主语从句）
this place is where they once hid.（表语从句）
