高考英语语法要点细讲精练状语从句
高考英语语法要点细讲精练状语从句【考纲解读】状语从句是高考的热点之一。
状语从句又称为副词性从句，包括时间状语从句、条件状语从句、原因状语从句、让步状语从句、目的状语从句、结果状语从句、方式状语从句等。
要求考生要充分理解和掌握状语从句的用法。
考查的重点集中在时间状语从句、条件状语从句、让步状语从句和目的状语从句。
试题的设置呈现综合性和交叉性，往往与定语从句和名词性从句结合起来考查，尤其对于不同性质的连词，要注意其在不同的语境中所表示的不同意义，例如as既能引导时间状语从句，又能引导原因状语从句和让步状语从句。
所以正确地把握题干的语境意义和上下文的逻辑关系，是做好状语从句试题的关键所在。
同时我们也要善于区分容易混淆的近似连词的用法。
由此可见，对状语从句的考查在将来的高考中仍是重头戏。
因此，在平常的学习中，理解、区分、掌握引导状语从句的关联词，搞清主从句的语意及逻辑关系，是做好状语从句题的关键所在。
【知识要点】定义：用来充当状语的句子称为状语从句。
功能：它主要用于修饰句子中的谓语动词、形容词或副词等，有时修饰整个句子。
位置：状语从句的位置较活：可以放在主句之前，用逗号与主句隔开；也可以放在主句之后，一般不用逗号。
由于它是从各个方面来修饰、说明谓语动词发生时的各种情况，所以常见的状语从句有九种之多。
各种不同的状语从句所使用的关系词也各不相同。
一、时间状语从句引导时间状语从句的从属连词有很多，现将分类用法如下：1.从属连词when，while与as连词用法谓语动词意义例句whe n从句的动作和主句的动作可以同时发生，也可以先后发生。
可以指时间的某个点，也指一段时间。
延续性动词非延续性动词当……时候When they heardthe news，they alljumped with joy.I owed Jack $ 100when I was inLondon.as 从句的动作与主句的动作同时发生。
可以指时间的某个点，也指一段时间。

状语从句（讲解部分由李沐洋和周丽丽整理；综合题部分由周丽丽整理）考点一时间状语从句由时间连接词引导的状语从句叫做时间状语从句。
引导时间状语从句的连接词1 when, while, as1)When当…时，可表一段时间，也可表时间点。
Eg: When I went home, my mum was cooking.It was raining hard when got to school yesterday.When I was a little girl, I wanted to be a teacher.2)While”当…时…”Eg: While I was watching TV, my mum was cooking in the kitchen.While I am listening to the music, my dad is watching TV.3)as (在…的同时；一边…一边…)Eg: As he walked along the lake, he sang happily.注意：由when, while, as引导的时间状语从句：When：引导的从句的谓语动词可以是延续性动词，又可以是瞬时动词While 引导的从句的谓语动词必须是延续性的。
Eg：While my wife was reading the newspaper, I was watching TV.(was reading 是延续性)As表示“一边…一边…”as 引导的动作是延续性的动作。
As we was going out, it began to snow.当我们出门时，开始下雪了。
2.since自从…since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。
一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。
I have been in Beijing since you left. 自从你离开以来，我一直在北京了。
Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了？It be+时间+since的句型中，主句多用一般现在时It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。
It is five months since our boss was in Beijing.我们老板离开北京有五个月了。
3 before，after1）before"在……之前"，引导时间状语从句时，表示主句动作发生在从句动作之前。
Eg: Close the door before you leave the room.离开房间前关上门。
He usually drinks a cup of tea before he goes to school.He had learned a little Chinese before he came to China.去中国之前，他就学过了一点中文。
2）after"在……之后"，引导时间状语从句时，表示主句的动作发生在从句的动作之后。
Eg: I went to bed after I finished my homework.做完作业后我就去睡觉了。
After he finished middle school, he went to work in a factory.注意：before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。
还要注意主句和从句之间的时间关系。
当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用，这样以便体现动作发生的先后。
After 表示主句动作发生在从句动作之后。
主句和从句的动作的时间关系正好与before引导的从句相反。
例如：It will be four days before they come back. 他们要过四天才能回来。
Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。
My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。
They had not been married four months before they weredivorced. 他们结婚还不到四个月就离婚了。
After you think it over, please let me know what you decide.你仔细考虑过以后，告诉我你是怎样决定的。
After we had finished the work, we went home.完成工作之后，我们回家了。
（从句用过去完成时，主句用一般过去时）He left the classroom after he had finished his homeworkthe other day.前几天做完作业之后回的家。
Mr. Brown had worked in a bank for a year before he camehere.布朗先生来这之前已经在一家银行里工作一年了。
4)till/until 直到…引导时间状语从句。
not ... until…主句谓语动词是非延续性动词until/ till ..."意为"直到……才……"主句谓语动词是延续性动词Eg: I'll wait here until / till he comes back.我将在这里等着，直到他回来。
You can't go home until / till you finish your work.直到你完成你的工作，你才能回家。
5)As soon as…一…就…引导时间状语从句时(主将从现)Eg: A s soon as she finishes her homework, she will play tennis.I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。
As soon as I finish this work, I will go home. 我一完成此工作，就回家。
考点二条件状语从句1.引导条件状语从句连词：2.1）if 如果…(主将从现)If it doesn’t ra in tomorrow, we will go hiking.如果明天不下雨, 我们就去远足.You will get good grades if you study hard.如果你努力学习,就会取得好成绩.We’ll start our project if the president agrees.2. unless 除非（=if not）I will go to the party unless he goes there too.（=If he does n’t go there, I will go to the party.）我会去参加聚会的, 除非他也去.(如果他不去,我就去.)You will be late unless you leave immediately. (=If you don’t leave immediately, you will be late.) 如果你不马上走,你将会迟到的。

当原因是显而易见的或已为人们所知，就用as或since。
I didn’t go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。
但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
He is absent today, because / for he is ill.He must be ill, for he is absent today.3) as和for的区别：通常情况下，as引导的从句在主句前，for引导的从句在主句后。
As the weather is cold, I stay at home.=I stay at home, for the weather is cold.考点四目的状语从句1 so that 以便于The boss asked the secretary to hurry up with the letters so that he could sign them.The teacher raised his voice on purpose so that the students in the back could hear more clearly.I’ll run slowly so that you can catch up with me.我将慢慢跑以至你能赶上我。
