中考状语从句要点
状语从句的复习重点及中考热点状语从句不仅是初中英语学习的重点，而且也是每年中考必考的内容之一。
从笔者研读历年全国各地中考英语试题对状语从句的考查内容来看，命题主要集中在引导状语从句的连词、状语从句的时态等方面；从九大状语从句来看，同学们应将复习重点放在时间状语从句、条件状语从句、结果状语从句和比较状语从句这四种上。
一、对时间状语从句的考查1．要点：1）引导时间状语从句的连词有：while，when，as，as soon as，until，not．．．until，before，after，since，etc．要掌握每个连词的含义及其用法，还有它们之间的一些区别。
2）when，while，as的区别：①三者均可表示“当……的时候”，如果主句表示的是短暂的动作，而从句表示的是一段时间，三者可通用。
如：I met Kang Li as／when／while I was walking along the street．当我沿街散步时碰见了康丽。
②as和when都可与终止性动词连用，while只能与延续性动词连用。
如：It was snowing when we got to the airport．当我们到达机场时，天正下着雪。
（不能用while）③as强调主句与从句表示的动作同时发生；while强调主句表示的动作持续于while所指的整个时间内；when可指主、从句所述动作同时或先后发生。
如：He sang as he went along．他边走边唱。
Please write while I read．我读的时候，请写下来。
When he reached home，he had a little rest．回到家后，他休息了一会儿。
3）until和till在肯定句中表示“直到……为止”，主句要用延续性动词；在否定句中，表示“直到……才”，主句常用终止性动词，这时till和until可用before替换。

注意：when 引导的时间状语从句中的谓语动词可以是持续的也可以是瞬时的;while和as 引导的时间状语从句中的谓语动词必须是持续的。
⑵一......就......：as soon as, the minute, the moment，the instant，immediately , directly, instantly, no sooner … than..., hardly …when..., scarcely…when...The children ran away from the orchard(果园) the moment they saw the guard.孩子们一看到守卫就从果园跑掉了。

中考状语从句考点
中考状语从句考点状语从句是中考必考的语法项目之一，它引导的状语从句在句中充当状语，修饰主句的谓语动词、形容词、副词或整个句子。
状语从句可分为以下九类：时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、方式状语从句、让步状语从句和比较状语从句。
一、考点解读1. 掌握引导词的用法。
引导词有：when（当……时候）、while（当……时候）、as（当……时候）、before（在……以前）、after（在……以后）、since（自从）、because（因为）、so that（以便）、as if（好像）、whether（是否）、though （虽然）、as long as（只要）等。
2. 掌握状语从句的时态。
主句是现在时态时，从句可为需要的任何时态；主句是过去时态时，从句要用过去的某种时态形式。
但客观真理除外。
3. 从句是祈使句或省略句时，需用陈述语序。
4. 从句的位置：时间、地点、原因状语从句通常放在主句之后；但当主句是祈使句时，从句通常放在主句之前；而当主句是一个完整的句子时，有时也可用从句作插入语。
5. 从句与主句之间不可存在逗号，需用连词连接。
6. 从句是therefore时，只放在主句之后，不能倒装。
7. 从句与主句的逻辑关系要清楚。
8. 从句中的关系代词that、which、who在任何情况下都不可以省略。
9. 连接词if、unless在引导条件状语从句时不能用and并列连接词。
在否定词not用在句首时表部分否定；但需用and并列连接词时表完全否定。
二、常考考点梳理1. 时间状语从句的考点：①表示“一……就……”的英语表达为“as soon as”，其用法为：“as soon as+主+谓+其他，主+can/may+动词原形+其他”。
例如：As soon as he finishes his homework，he will go to the library. 他一完成作业就要去图书馆。

中考状语从句之原因、结果、目的状语从句：知识点+习题 ( 无答案）原因、结果、目的状语从句一、原因状语从句(1)原因状语从句通常由because, since, as, for 引导。
(2)because 表示直接原因，语气最强。
because 引导的原因状语从句多放在主句之后。
回答由why 提出的问题，只能用b eca us e。
此外，because 和so 不能同用在一个句子里。
例如：------Why aren't going there?------Because I don't want to.→ since 引导原因状语从句，相当于now t h at，意思是“因为……，既然……，鉴于……”。
例如：Since the rain has stopped，let's go for a walk. 既然雨停了，我们出去散散步吧。
→ as 和since 语气较弱，一般用来表示明显的原因。
由as 和since 引导的原因状语从居多放在句首。
例如：As he has no car, he can't get there easily. Since wehave no money, we can't buy it.(3)for 表示所说的理由是一种补充说明,for 引导的从句一般不放在句子的开头。
如:I decided to stop and have lunch, for I was feeling quite hungry.练习：I was late for class yesterday there was something wrong with my bike. He tookoff his coat he felt hot.you can't answer the question, I'll ask someone else.二、结果状语从句(1)结果状语从句由so…that, such…that, so that 引导。
2)so…that 语such...that 可以互换。
在由so...that 引导的结果状语从句中，so是副词，与形容词连用。
其结构是: “...so + 形容词（副词）+ that + 从句”。
例如：He was so glad that he couldn't say a word.Mother lives so far away that we hardly ever（几乎不，从来不）see her.→在由such…that 引导的结果状语从句中，such 是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；其结构是: “...such +a / an + 形容词+名词+ that + 从句”。
例如：It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.（天花板）→ 有时上述两种结构是可以互换的。
例如：It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.(3)如果名词前由many, much, little, few 等词修饰时，只能用so, 不用such。
例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he can't go to the cinema with you.(4)如果主从句的主语相同，并且从句是否定的形式，可以用too...to...句型转化。
例如：He was so excited that he couldn't go to sleep that night. = He was too excited to go to sleep.(5)如果主从句的主语相同，但从句是肯定的形式，可以用adj.+ enough 替换。
例如：He is so old that he could go to school. = He is old enough to go to school. 他够大了，可以去上学。
练习：It is hot in the room we have to go out for a walk. It was awonderful movie all of us wanted to see it again.There were little water in the bottle the bird couldn't reach it.【练习】用so…that…或者such…that…填空：1. It was hot in the cinema I felt very uncomfortable.2. It was a funny film I laughed until I cried!3. few people came to see the film the manager put on another film instead.4.Tom hurt his legs badly he was not able to walk for six months.5.There were many people at the party our house got too crowded.6.Joy has a strong love of films she goes to the cinema every week.三、目的状语从句(1)目的状语从句通常由so that, in order that（为了，以便）引导。
例如：We started early so that we could catch the first train.We used the computer in order that we might save time.(2)so that 可引导目的状语从句，此时可用to 或in order to 替换,将其改为简单句。
例如：He got up early so that he could get to school on time.=He got up early（in order）to get to school on time.(3)so that 既可引导目的状语从句，又可引导结果状语从句。
区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might 等。
2)从意思上看，目的状语从句往往表示的目的很明确。
例如：Speak clearly so that they may understand you. (目的状语从句) Jack isbadly ill so that he has to rest. (结果状语从句)练习：I hurried I wouldn't be late for class.We should go by bus we can get there earlier. May I sitnearer I can see more clearly?(4) 补充：so as to…(肯定结构) eg. He got up early so as to catch the early train.so as not to…(否定结构) eg. He got up early so as not to miss the early train. to…eg.He got up early to catch the early train.in order that … eg. He got up early in order that he could catch the early train. in order to…eg. He got up early in order to catch the early train.【练习】一、单项选择。
