状语从句的9种形式口诀
状语从句讲解
状语修饰动词、形容词、副词或整个句子.通常由副词、介词短语、动词不定式、分词和从句等担当.例如：
1.Naturally ,our grandparents were pleased to get our phone call .(副词)
2.We worked hard ,from sunrise to sunset .(介词状短语)
3.To help my disabled aunt ,I spend an hour working in her house every day .(不定式)
4.Seen from a distance ,the farmhouse looked deserted .(过去分词)
5.I know how to light a camp fire because I had done it before .（原因状语从句）
状语的位置比较灵活,可以位于句首、句末或句中.enough用作状语修饰形容词和副词时必须后置.
状语从句主要用来修饰主句或主句的谓语.一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式.尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难.状语从句的关键是要掌握引导不同状语从句的常用连接词

(二)原因状语从句
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that(既然)等，for 表示因果关系时(它引导的不是从句)为并列连词，语气不如because强。
e.g. He is disappointed because he didn't get the position.

Now that you mention it, I do remember.
(三)地点状语从句
引导地点状语从句的连词是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
(四)目的'状语从句
引导目的状语从句最常用的词(组)是so, so that(从句谓语常有情态动词), in order that, in case(以防，以免)等。
e.g. Speak clearly, so that they may understand you.
She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
(五)结果状语从句
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that (从句谓语一般没有情态动词), so … that, such … that等引导。
e.g. She was ill, so that she didn't attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
(六)条件状语从句
条件状语从句分真实性(有可能实现的事情)与非真实性(条件与事实相反或者在说话者看来不大可能实现的事情)条件句。引导条件状语从句的词(组)主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether替换。
e.g. If he is not in the office, he must be out for lunch.

The busier he is, the happier he feels.
(十)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。
e.g. 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(或虽不一致，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。
e.g. 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。以where为例，能引导多种从句。
e.g. You are to find it where you left it.(地点状语从句)
Tell me the address where he lives.(定语从句，句中有先行词)
I don't know where he came from.(宾语从句)
Where he has gone is not known yet.(主语从句)
This place is where they once hid.(表语从句)
