2018年公共英语三级语法学习技巧：状语从句

　　状语从句

　　状语从句是指在主句中作状语的主谓结构。状语从句根据其在主句中的句法作用可分为时间、地点、方式、原因、目的、结果、让步、比较和条件等九种状语从句。掌握状语从句的关键是熟悉能连接状语从句的从属连词的用法。下面以原因、让步、条件状语从句为例子来说明

　　考点分析

　　能连接原因状语从句的从属连词有：because, as , since, for, in that (因为),now that (既然)等。考点有：

　　1)in that, now that 引导的状态语从句，这是四级测试的一个重点。

　　2)as, because ,for 和since 引导原因状语从句的区别。笔者认为，应从两个层次对之进行区分：一是从句与主句的位置，二是从句与主句的关系。As 引导的从句常位于主句之前，它说明的原因只是附带性的;because 引导的从句一般放在主句之后，它用来表示直接原因;for引导的从句只能放到主句的后面，它侧重于对主句的解释和说明;since引导的从句常放在主句的前面，特别是表示“既然”时，它表示的原因通常是稍加分析后推断出来的。
