八种状语从句
八种状语从句状语从句在句中作状语,修饰主句中的动词、形容词和副词等。
按其作用和意义可分为时间、原因、目的、结果、条件、让步、方式、比较八种。
下面对这八种从句的要点加以总结。
一、各类状语从句的引导词及易混词的区别。
1. 时间状语从句1) 引导词(1)表示“当……时候”:when, while, as, whenever(2)表示“一……就……”:as soon as(3)其它:after, before, since, until, by the timeWhenever he comes, he brings a friend. 他每次来都带个朋友。
I want to see him as soon as he arrives. 他一来我就要见他。
I went to bed after I finished my homework. 我做完家庭作业之后才睡觉。
2) 易混引导词when, while, as 的区别when既可指“时间点”,与瞬时动词连用,也可指“时间段”,与延续性动词连用(这时可与while互换)。
如:When he came in, his mother was cooking. 他进来时,他妈妈正在烧饭。
When(While)we were at school, we went to the library every day. 我们在校求学时,每天都到图书馆去。
while 只表示时间段,因此while从句的谓语动词要用延续性动词。
Please don' t talk so loud while others are talking. 别人在工作时,切勿大声讲话。
as 与when 用法相似,但着重强调主句动作与从句动作同时发生,有“随着……”或“一边……一边……”之意。
She sang as she went along. 她边走边唱。
As you get older, you get more knowledge.随着年龄的增长,你获得的知识就越多。

(3)so that既可引导目的状语从句,又可引导结果状 语从句。区别这两种从句的办法有两个:
A)目的状语从句里往往带有情态动词 can, could, may, might等。
B)从意思上看,目的状语从句往往表示的目的很明确, 不放在句首。 例如: Speak clearly so that they may understand you. (目的状语句) Jack is badly ill so that he has to rest. (结果状语从句)
something wrong with my bike. because 2. He took off his coat _______ he felt hot. 3.________you can’t answerfothr e question, I’All sa/sskinscoemeone else.

结果状语从句
9
(1)结果状语从句由so…that, such…that, so that引导。 (2)so…that与 such...that可以互换。在由so...that引导的 结果状语从句中,so是副词,与形容词连用。其结构 是: “...so + 形容词(副词)+ that + 从句”。 例: He was so glad that he couldn’t say a word. Mother lives so far away that we hardly ever(几乎不, 从来不) see her.7来自用于目的状语从句,还有:
so as to…(肯定结构) eg. He got up early so as to catch the early train.
so as not to…(否定结构) eg. He got up early so as not to miss the early train.

(2)在由such…that引导的结果状语从句中,such是形
容词,它修饰的可以是单数或复数可数名词,也可以 是不可数名词;其结构是: “...such +a / an + 形容词+名 词+ that + 从句”。 例如:
1.It was such a hot day that nobody wanted to do anythi ng. 2.He had such long arms that he could almost touch the ceiling.(天花板)
(2)so that可引导目的状语从句,此时可用to或in order to 替换,将其改为简单句。 例如:
He got up early so that he could get to school on time. =H e got up early(in order) to get to school on time.
原因目的和结果状语从句

1
(1)原因状语从句:从句表示的是主句行为的原因。通常 由because, since, as, for引导。 (2) because表示直接原因(听话人所不知的),语气最强。 回答由why提出的问题,只能用because。此外,because 和so不能同用在一个句子里。
2
as和since语气较弱,一般用来表示明显的原因。 由as和since引导的原因状语从句多放在句首。 例如 :As he has no car, he can’t get there easily. Since we have no money, we can’t buy it.
(4)for表示所说的理由是一种补充说明,for引导的从句一 般不放在句子的开头。 如: I decided to stop and have lunch, for I was feeling qu ite hungry. Eg: 1. I was late for class yesterday _______ there was
