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 outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be ，就可省略从句中的“主语 + be”部分。
E.g. When (he was) still a boy of ten, he had to work day and night.
If (you are) asked you may come in.
If (it is) necessary I’ll explain to you again.
3、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 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）
4、as作从属连词可引导多种状语从句。
（1）as引导时间状语从句，意为“当…时”。例如：As (he was) a young man, he was a storekeeper and later a postmaster./ He sang as he worked. 高.考.资.源.网
（2）as引导方式状语从句，意为“象…一样”。例如：We must do as the Party teaches us.
（3）as引导原因状语从句。意为“由于”，例如：As you are tired, you had better rest.
（4）as引导让步状语从句。意为“虽然”、“尽管”Child as he is, he can do it well. ( = Although he is a child, he can do it well.) 另外，as做为关系代词还可以引导定语从句，如：I have the same book as you.
