使用状语从句时要注意的几个问题
1、在时间和条件（有时也在方式、让步等）从句中，主句 是一般将来时，从句通常用一般
现在时表示将来。
e.g. We’ll go out if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
2、注意区分不同从句：引 导的是什么从句，不仅要根据连词，还要根据句子结构和句意来
判别。以where为例，能引导多种从 句。
e.g. You can find it where you left it.（_____________从句）
Tell me the address where he lives.（__________从句）
I don’t know where he came from.（__________从句）
Where he has gone is not known yet.（________从句）
