高中九大状语从句详细解析+例句
状语从句Adverbial ClauseI 定义和分类一、定义在复合句中充当状语的从句叫状语从句。
状语从句通常由从属连词或起连词作用的词组引导。
试比较下列两句句子：1.I will return the book to him tomorrow. 我明天会把书还给他。
2.I will return the book to him when I meet him. 我见到他时会把书还给他。
分析在句1中，副词tomorrow作为时间状语在修饰动词return。
在句2中出现了两个谓语动词，分别是return和meet，表示有两句句子存在。
句2中的when I meet him取代了句1中tomorrow的位置。
when作为状语从句的引导词（即从属连词）连接起了主句I will return the book和从句I meet him两部分。
在分析主从句时，可以通过确定谓语动词和连词来将长句变为短句，从而便于理解句子的意思。
二、分类状语从句根据它表达的意思不同，可以分为以下基本的九类：1.时间状语从句，例如：When he arrived home last night, it was just nine o'clock. 昨晚他到家时恰好九点。
2.地点状语从句，例如：I put the book back where it had been. 我把书放回了原处。
3.原因状语从句，例如：It is inexpensive to produce because it is made from corn.由于是玉米做成的，它的生产成本不高。
4.目的状语从句，例如：They took a subway in order that they might not be held up in the traffic.为了不被堵在路上，他们搭乘了地铁。
5.结果状语从句，例如：The village is so small that it cannot be shown in the map.这个村庄太小了以致于在地图上都找不到。

tips:只用as不用when或while的情况1、用于表示同一个人的两种动作交替进行，指“一边…一边…”，如：The girl sings as she goes to school.2、表示两个同步发生的动作或行为如：As time went by,she became more and more beautiful.3、表示两个动作紧跟着发生，如：As he was going out,it began to rain,4、接在名词后面表示某一个年龄段时。
如：As a young man, he was active in sports.连接词when,while,as的用法区别1、while引导的时间状语从句的谓语动词必须是可持续的，而when引导的时间状语从句的谓语动词既可以可持续的，也可以是表短暂性动作的动词。
When\While he was eating his breakfast,he heard the door bell rang.When I stopped my car,a man came up to me.(while不可用)2、从句动作发生在主句动作之前时，只能用when 引导，不可用while\as, 如：When you have finished your work,you may have a rest3、表示“随着……”,连词用as,不用when\while,如：As the election approached,the violenve got worse.4、如果主句表示的是短暂性的动作，从句用延续性动作的进行时态表示一段时间内正在进行的动作时，三者可互相交换使用。
如：When\While\As I was walking down the street,I came across an old friend of mine.till,until和not…until用法1、until\till引导时间状语从句用于肯定句中时，主句的动词时延续性动词，表示动作或状态一直持续到until\till所表示的时间，意为“某动作一直持续到某时间点才停止”，译为“直到…为止”。
