1、1Unit 6 An old man tried to move the mountains单元语法专练状语从句状语从句在复合句中修饰主句中的谓语动词、形容词或副词。状语从句一般由从属连词引导。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。状语从句分类如下:类型 引导连词时间状语从句when,before,after,as,while,as soon as,since,not.until.,whenever 等原因状语从句 because,as,since 等条件状语从句 if,unless 等比较状语从句 as/so.as.,than 等结果状语从句 so.that.

2、等目的状语从句 in order that,so that 等让步状语从句 although,even though 等本单元着重介绍了以下三种状语从句。1.unless 引导的条件状语从句。unless 意为“如果不;除非”,相当于 if.not。例如:2Well go to the town unless it rains tomorrow.=Well go to the town if it doesnt rain tomorrow.假如明天不下雨,我们就去城里。注意:unless 和 if 引导条件状语从句时,从句用一般现在时表示将来,而主句则用一般将来时,即遵循“主将从现”原则。2.

3、as soon as 引导的时间状语从句。as soon as 意为“一就”,表示从句和主句的动作先后发生,间隔短暂。例如:The students became quiet as soon as the teacher came in.老师一进来,学生们就安静下来了。注意:在条件状语从句和时间状语从句中,也可遵循“主将从现”原则。例如:Ill call to you as soon as I get there.我一到那里就给你打电话。3.so.that.引导的结果状语从句。so.that.意为“如此以至于”,其中 so 后接形容词或副词,也可用few,little,many,much 等来
