1 熟悉这九大类别的状语从句的不同的连接词的意义和用法
2准确判断主从句的逻辑关系，同时还要注意区分词义相近的连词、介词和副词  
3 解题的过程中要注意时态、语态、语气、语序的统一
4加强各个类别的状语从句的的分析和理解练习

特殊引导词：

（十）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  
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  
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  
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）
