按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。

目的状语从句的谓语常含有can/could/may/might/will/would等情态动词。
He ran as fast as possible in order that he could catch the bus.Please remind me of it again tomorrow in case I forget.五、方式(或比较)状语从句引导词有as, as if, as though, the way, than, as/so…as,the more…the more.It looks as if it is going to rain.My teacher treats us as if she were our mother.Sometimes we teach our children the way our parents have taught us.Tom is not so/as tall as John.He runs faster than I.注:as…as可用于肯定句或否定句,so…as只能用于否定句。
六、结果状语从句引导词有so…that,such…that, so that.(意思是“如此…以致…)He works so hard that he makes great progress in his studies.It’s such a difficult problem that nobody can work it out.(从句不是目的,没有can, may)There’s not any noise here so that I feel very comfortable.※修饰形容词、副词只能用so.He walked so fast that I couldn’t keep up with him.※修饰many, much, few, little (少) 时,习惯用so.There were so many books in the shop that he didn’t know which to buy.※修饰可数名词单数可用so或suchIt is such an interesting book (= so interesting a book) that we all like it very much.※修饰不可数名词或可数名词复数时,用such.The villagers were such kind people that they all came to help us.七、条件状语从句引导词有if, unless, as/so long as, on condition that, in case(万一,如果),从句的时态用一般现在时(含现在完成时),一般过去时(含过去完成时)分别代替一般将来时和过去将来时。
If it rains tomorrow, I won’t go there.He said he would not go back home unless he had achieved a lot.I’ll study so long as I’m alive.In case he come, let me know.They can't leave unless they have done their work.※If 引导的条件句可以是真实性条件句,也可以是非真实性条件句(用于虚拟语气)八、让步状语从句引导词有though, although, even if, even though, as, whoever, whatever,however, no matter+what/w ho/when/…等。
Though/Although he is ill, he still goes to school.She started her experiment, even though she had little money.Whatever you found, you must turn it in.However hard he worked, he hardly made any progress.※ as 作“尽管, 虽然”意时,常用倒装句式。
Try as he would, he couldn’t lift the heavy box.Young as he is, he knows a lot.=Although he is young, he knows a lot.若表语为名词,冠词要省略。
Child as/though he is, he has remembered a lot of English words.(though不可换为although) although或though不能与but同时出现在一个复合句中,但是“Although/Though…,(and)yet…”句式却是正确的。
Although it is raining heavily, yet they are repairing the bridge.九、使用状语从句时要注意的几个问题1、在时间和条件(有时也在方式、让步等)从句中,主句是一般将来时,从句通常用一般现在时表示将来。
We’ll go outing if it doesn’t rain tomorrow.I’ll write to you as soon as I get to Shanghai.2、有些时间、地点、条件、方式或让步从句,如果从句的主语与主句主语一致(或从句主语是it),从句的谓语又包含动词be ,就可省略从句中的“主语+ be”部分。
When (he was) still a boy of ten, he had to work day and night.If (you are) asked you may come in.If (it is) necessary I’ll explain to you again.3、注意区分不同从句:引导的是什么从句,不仅要根据连词,还要根据句子结构和句意来判别。
