状语从句本章节内容1. 状语从句的概述中考对状语从句的考查会和从属连词相结合，主要为在状语从句中考查从属连词的辨析及应用。

常见的有although/though/even though引导的让步状语从句。

if/unless引导的条件状语从句。

until/when/while/as soon as引导的时间状语从句。

because引导的原因状语从句，so that引导的目的状语从句等。

if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合，即主要考查“主将从现”原则。

对于状语从句的学习可与专题六从属连词相结合。

在时间状语从句和条件状语从句中，主句和从句的时态一致问题一般有两种情况：（1）“主将从现”：主句用一般将来时，而从句用一般现在时。

常见的使用“主将从现”原则的连词有：表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等；表示条件的if, unless, so long as, in case等。

（2）“主祈从现”：若主句是祈使句，或主句中有情态动词时，那么从句用一般现在时表示将来。

（3）“主情从现”：若主句有情态动词, 那么从句用一般现在时表示将来。

如：You can get good grades if you study hard. 如果你努力学习，你将取得好成绩。

1状语从句的概述状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。

状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。

2时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。

I’ll ring you up as soon as I get to Beijing.我一到就给你打。

连接词类别
作用 as 表示“当„„的时候”，往往和 when/ while 通用，但它着重强调主句与从句的动作或事情同 时或几乎同时发生。
例句 1.She came up as I was cooking.（同时） 2.The runners started as the gun went off.（几 乎同时） 1.When we were at school, we went to the library every day.（在一段时间内） 2.Sorry，I was out when you called me．（ call为短暂性动词）对不起，你打电话时我 刚好外出了。 3. When I got to the airport，the guests had left．（got to后发生）当我赶到飞机场时， 客人们已经离开了。 1.When ／While ／As we were dancing，a stranger came in．（dance为延续性动词） 。 2.Please don’t talk so loud while others are working.
8、比较状语从句 常用引导词:as(同级比较), than(不同程度的比较) 特殊引导词:the more … the more … ; just as …, so…; A is to B what /as X is to Y; no … more than; not A so much as B 例句 She is as bad-tempered as her mother. The house is three times as big as ours. The more you exercise, the healthier you will be. Food is to men what oil is to machine. 食物之于人,犹如油之于机器。

状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。

状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。

下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。

由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。

例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。

从句动作可与主语动作通常先后发生也可同时发生。

I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。

(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。

While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。
