forest,写作步步高,如何写好状语从句,状语从句修饰主句中的动词、形容词和副词，由从属连词引导，可位于句首，也可位于主句后。状语从句在句首时，往往有逗号使从句与主句隔开。,引导状语从句的连词分类（如下表）：,状语从句,连词,时间,when,whenever,as,while,before,after,till,until,as,soon as,hardly.when,no sooner.than,scarcely.when,each time,every time,the first time,the last time,the moment,the minute,the second,the,day,immediately,地点,where,wherever,everywhere,条件,if,unless,providing/provided that,supposing/suppose that,as long as,so long as,on condition that,in case,only if,if only,原因,because,as,since,now that,seeing that,considering that,in that,in view of the fact(鉴于),让步,though,although,even if,even though,as,while,whatever,whoever,whenever,wherever,however,no,matter wh,for all that,granting,granted,whether.or.,in spite of the fact that,比较,as,than,the same as,not so.as,as.as,方式,as if,as though,目的,that,in order that,so that,in case,for fear that,lest,结果,so that,so.that,such.that,but that,在写好简单句的基础上，要写好含状语从句的复合句，掌握引导每种状语从句的连词是关键，因为状语从句内的结构与简单句相同，我们需要什么状语从句，只需在句前加上相应的连词即可。当然我们还需分清复合句中哪是主句，哪是从句。,如：（1）,当你再读这首诗后,，,你将更明白它的含义,。,（从句）,（主句）,When,you read the poem a second time,you will understand it better.,从句中，除了多了连词When外，you read the poem a second time与简单句结构相同。,（2）客人们每到一处，都受到热烈欢迎。,Wherever,they went,the guests were warmly welcomed.,The guests were warmly welcomed,wherever,they
