状语从句
【定义】在复合句中修饰主句中的动词、形容词或副词,起状语作用的从句叫状语从句。状语从句可置于主语之前,也可置主语之后。前置时,从句后用逗号与主句分开;后置时,与主句之间没有标点符号。状语从句可为时间、原因、目的、结果、条件、比较、地点、让步、方式等九类。
1. 结果状语从句
例:Curing sick people is _____ important ____ doctors must be careful.
A. too; to B. so; that C. enough; to D. such; that
(1) 结果状语从句由so...that, such ... that引导
He is _________ poor _________he can’t buy a bike for his son.
他是如此的贫穷,以致于不能给他的儿子买辆自行车。
She is _______ a good teacher _________ everybody likes her.
她是一位如此好的老师,以致于每个人都喜欢她。
(2) so... that 与 such... that
1) 在由so...that引导的结果状语从句中,so是副词,与形容词连用。结构是:
so + 形容词(副词)+ that + 从句
2) 在由such... that引导的结果状语从句中,such是形容词,后面跟名词,该名词可以是可数名词或不可数名词;如果是单数可数名词,前面需加不定冠词a或an.
It was such a hot day that nobody wanted to do anything.
He was so glad that he couldn’t say a word.

2. 目的状语从句

(1) 目的状语从句通常由so that, in order that 引导
We started early so that we could catch the first train.
We used the computer in order that we might save time.
(2) so that既可以引导目的状语从句,又可引导结果状语从句。区别方法有2种:
1)目的状语从句里往往带有情态动词can, could, may, might等。
2)从意思上看,目的状语从句往往表示的目的很明确。
Let’s work together so that we can make our country more beautiful. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
