状语从句
什么是状语从句?
在句中起状语作用的从句叫作状语从句。状语从句都是由从属连词引导的,主要包括时间状语从句,地点状语从句,条件状语从句,原因状语从句,目的状语从句,结果状语从句,让步状语从句,方式状语从句和比较状语从句。 本单元主要学习由until引导的时间状语从句,so that引导的结果状语从句,以及although引导的让步状语从句。
until/till 引导的时间状语从句:till/until意为:“直到...为止”。主句如果是肯定句,谓语动词需要用延续性动词,表示主句的动作一直持续到till/until表示的时间。
e.g. I will wait for you till/until you come back.
We will have dinner till/until Linda comes back.
主语如果是否定句,谓语动词要用非延续性动词,表示主句的动作直到till/until表示的时间才发生,此时“not...till/until”意为“直到...才...”
e.g. I didn’t go out until/till my parents came back.
You can’t leave until you finish your homework
Tip:until与till的区别:till不可以置于句首,而until可以。
e.g.Until she spoke I hadn’t realized she wasn’t English.
直到她开口说话我才知道她不是英格兰人。
②so that
引导的结果状语从句:so that 引导结果状语从句时,意为“结果,以至于”,从句前有时用逗号与主句分开。
e.g.He worked hard at school,so that he got good grades in the final exam.
区分so that 与so.....that...的用法:
so...that..表示“如此...以至于...” ,so that表示“结果,以至于”。
e.g.I got a fever,so that I won’t go to school. He’s so clever that he can work out the problem.
③ 让步状语从句:表示与主句相反的某种条件或者情况,但从句所表示的这些不利因素并不能阻止主句的动作发生,即在相反条件,主句的情况依然存在。引导让步状语从句的从属连词主要有though/although(尽管),even if/even though(即使)
although/though 引导的让步状语从句: though/although的意义相同,多数情况下可以互换。though/although引导让步状语从句时,主句可用yet或still,但不可使用but。
e.g.Although we worked all day, we were not tired.
Although the girl is only nine,she takes care of her brothers and cooks meals every day(南昌中考)
Although/Though it was raining hard,yet they went on playing basketball.
