中考关于状语从句的讲解和练习

中考关于状语从句的专项讲解及练习
状语从句是初中英语学习的重点，也是每年中考必 考的内容之一。主要考查引导状语从
句的连词、从句时态等方面，考查包括时间状语从句、条件状语从句 、结果状语从句和比较
状语从句。
1、时间状语从句
1）要掌握引导时间状语从句 的连词，连词的含义、连词的用法以及它们之间的区别。主
要连词有：while, when, as, as soon as, not…until, before, after, since等。
2）when, while, as的区别：
三者都可以表示“当……时候”，如果主句表 示的是短暂的动作，而从句表示的是一段时间，
三者可以通用,例句I met Mary whenwhileas I was walking along the street.
as和when都可以与终止性动词连用，而while只能和延续性动词连用，如It was snowing when
we got to the airport.
as强调主 句和从句的动同时发生；while强调主句动作持续于while所指的整个时间内；when
可以指 主句、从句所述的动作同时或先后发生，如例句He sang as he went along.
Please write while I read. When he reached home,he had a little rest.
3）until和till在肯定句中的意 思是“直到……为止”，主句要用延续性动词；在否定句中
的意思是“直到……才”，主语经常用终止性 动词，这个时候till, until这两个词可以用before
来替换。例句：I waited tilluntil he arrived. We won’t start tilluntilbefore Bob comes.
4）since从句常用过去时，主句用一 般现在时或现在完成时；如果主句是一般将来时，情
态动词加动词原形或祈使句的时候，时间状语从句用 一般现在时。看下面两个例句:Where
have you been since I saw you last time? I’ll phone you as soon as I arrive in Beijing.
2、条件状语从句
You will fail unless you study hard. You will fail if you don’t study hard.
引导条件状语从句的连词有if（如果），unless（除非）等,unless在意义 上相当于if…not。
条件状语从句和时间状语从句一样，如果主句用将来时，从句要用现在时态表 示将来，也就
是我们常说的“主将从现”。
3、比较状语从句
引导比较状语从句的连词有as…as, than等。注意下面两种情况：
1）表示甲乙在 某一方面相同的时候，用“as+原级+as”结构；如果表示甲在某方面不如
乙的时候，用“not as so+原级+as”结构。例句：
Da Lian is as beautiful as Shen Zhen. I don’t run as fast as John.
2）表示 甲超过或者不及乙的时候，用“比较级+从句”（从句中经常省略意义与主句相同
的部分）。例句：He runs faster than you. Today is less cold than yesterday.
4、结果状语从句
引导结果状语从句的连词有so…that…（如 此……以至于……），such…that…（如此……
以至于……）等。常用句型：
so+形容词副词+that从句；
so+形容词+a an+单数可数名词+that从句；
such a an +形容词+单数可数名词+that从句；
such +形容词+复数可数名词不可数名词+that 从句；看下面例句：
He spoke so fast that I couldn’t follow him. He told us such funny stories that we all laughed.
5、其他状语从句
除了上面四种，还有地点、原因、目的、方式 、让步状语从句等五种，需要大家掌握的考

点有下面几个：
1）引导地点状语从句的有：where, wherever等，例句：
Where there is a will, there is a way. Wherever you go,I go too.
2）引导原因状语从句的有：because, since等。Beca use常常回答why引导的疑问句，从句
一般放在主句的后面；而since和as正式，这两个不回 答why问句，而且从句一般放在句
首：Why can’t I go? Because you are too young.
AsSince you are not feeling well,you’d better stay at home.
3）引导目的状语从句的有：so that（以便）等；
I packed him a little food so that he wouldn’t be hungry.
4）引导方式状语词的有as（按照）等；
I will do it as you tell me.
5）引导让步状语从句的有though although（虽然）, even though（尽管）, whoever no matter
who（无论谁）, however no matter how（无论怎样）, whatever no matter what（无论什么）
等，例句:Though it’s hard work I enjoy it. No matter how hard the work was, I never gave it up.
最后，大家要注意的是because不能和并列连词so连用；though although不能和but同
时使用，例如：Though it’s not cheap,it’s very good.
