英语语法大攻克--状语从句讲解(整理)

初三英语中考语法考点重难点详解（七）状语从句的时态知识点整理总结（含主将从现）中考英语对状语从句的考查，主要集中在时间状语从句和条件状语从句，首先要知道状语从句的作用，描述主句动词发生的“样子”：发生的时间、地点、条件、原因等等。

1、主句是祈使句或者含有情态动词的现在式，这个时候，从句多用一般现在时，例如：He can pass the exam if he studis hard.Tell me if he comes.2、主句用过去进行时，从句用一般过去时，例如：Mom was cooking when I got home.She was praticing the piano when I called.这种情况本质就是过去进行时的功能：表达过去某个时间点正在发生的动作，而从句中的动词往往是个瞬间动词，这个动作的发生（如got home，called）刚好对应着过去的一个“时间点”。

3、主句从句都用过去进行时，这个时候连词用while，例如：While I was doing my homework, mom was cooking in the kitchen.I was sitting in the sun while wy wife was working in the garden.这种情况其实是考试连词while的含义：在……的过程中，这样从句的动词就需要一个“延续性”动词，才能和while 配合完美。

4、关于条件句的用法，是出题人最喜欢采用的If he comes, give him the picture.（主句是祈使句，天剑局是一般现在时）If we try our best, we'll get good grades.主将从现是一般原则，但是要注意也有很多不是主将从现的主从句配合。

补充知识点：“主将从现”首先我们知道一个句子的成分包含，“主谓宾定状补”，那么在句中作状语的从句称为状语从句。

状语从句1.引导状语从句的连词时间状语从句when（as、while）（当……时候）、since（自从）、before（在……之前）、after（在……之后）、until（till）（直到……才）、whenever（每当）、once （一旦）、every time（每当）、the day（在……那天）、as soon as（一……就）、hardly（scarcely）……when（一……就）、no sooner……than（一……就）、instantly（immediately、directly）（一……就）、the moment（minute、second、instant）（一……就）地点状语从句where（在……地方）、wherever（在任何地方）、every where（在每个地方）原因状语从句because(as、for)（因为）、since（既然）、when（既然）、now（that）（既然）、in that（因为、既然）条件状语从句if（如果）、unless（除非）、as（so）long as（只要）、providing （provided）（that）（假如）、suppose（supposing）（that）（假如）、in case（如果）、only if（如果）、if only（但愿、如果……就好了）、on condition that（条件是）让步状语从句though（although）（虽然）、even if（even though）（即使）、while（虽然、尽管）、whatever（no matter what）（无论如何）、whenever（no matter when）（无论何时）、wherever（no matter where）（无论哪里）、whoever（no matter who）（无论谁）、however（no matter how）（无论怎样）、for all（that）（尽管）、granting（granted） that（即使）、whether……or（不论……还是）、in spite of （despite）the fact that（不管）结果状语从句so that（so、that）（结果）、so（such）……that（如此……以至于）、but that（but）（要不是）目的状语从句so that（so、that）（为了、以使）、lest（以防）、in case（以防、以免）、for fear that（以防）、in order that（为了）比较状语从句than（比……）、as……as（像……一样）、not so（as）……as （不像……一样）、（not）the same as（（不）同……一样）、not so as（不如）、（not）such……as（（不）如……）方式状语从句as（像……、犹如……）、as if（as though）（好像、仿佛）、the way（……的样子）2、时间状语从句（表示时间的状语从句）①when、whenever、while和aswhen意为“当……时候”，表示某个具体的时间。

状语从句一．分类：when (当……的时候) while (在……期间) as (当……的时候, 一边……一边……)before (在……之前) since (自从……以来) till/until (直到) hardly…when… (刚……就) as soon as (一……就……)after (在……之后) not…till/until（直到……才）no sooner…than…(刚……就) 地点状语从句：where (在那里) wherever(无论哪里)原因状语从句：because (因为) since (因为，既然) as (由于) for (为了) now that（既然）目的状语从句：（so）that=in order that（以便）so as（not）to （以便[不]）in case（以免）lest（以免）结果状语从句：so+adj./adv.+that（如此……以致）so that（结果……）such+n.+that（如果……以致）that（所以，因此）让步状语从句：though/although不可同but连用。

though/although （虽然）however （可是）even though/if（即使）no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever（不论什么/哪一个/哪里/谁/何时）比较状语从句：as （正如）as…as（和……一样）not as/so … as （不如……）than（比……更）the+比较级…+the+比较级（越……越……）条件状语从句：if（假设）unless（如果不）so long as（只要）on condition that （如果）方式状语从句：as（像……那样地）just as（正像）as if（好像）as though（好像）二．各种状语从句的简化方法：1作状语。

英语-时间状语从句定义：状语从句是指句子用作状语时，起副词作用的句子。

它可以修饰谓语、非谓语动词、定语、状语或整个句子。

时间状语从句表示时间发生的先后关系。

知识梳理：（一）when，while和as引导时间状语从句的用法一、when的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。

1. When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。

2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。

3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。

5. He was on the point of leaving when someone knocked at the door. 他正要走，这时有人敲门。

6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。

7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。

由以上内容可知，when 从句的A 事件，相当于另一个事件 B 发生的时间点。

也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。

因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。

实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。

状语从句由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。

第一讲时间, 地点状语从句时间状语从句：when, while, as, before, after, since , wheneveruntil, till, by the time(注意时态)as soon as, had hardly…when, had no sooner…than, (on doing sth…)the moment, every time/ each time, the first time, oncee.g: When he came, I had cleaned the classroom.He didn’t stop working until his mother came bake.He worked until his mother came back.As soon as he returned, he bought a new flat.He had no sooner returned than he bought a new flatHe came to scene the moment he heard the news.I thought her nice and honest the first time I met him.Once he makes up your mind, he won’t change his min d.It was two years before I met him again. = Two years passed before I met him again.注意点1. when引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的；while有时并不表示时间，而表示对比，表示“而”、“却”。

英语语法：状语从句八大类型的区分以及知识点讲解NO.1 副词作状语(1)句子副词：句子副词用于修饰句子(而不是修饰某个单个的词)，反映说话人的观点和看法。

如actually, apparently, certainly, clearly,definitely, evidently, fortunately, frankly, honestly, luckily, obviously, perhaps, possibly, probably, surely, undoubtedly, unexpectedly 等。

作用以及位置：句子副词通常位于句首(或分句句首)。

Eg:Obviously he can't tell the difference between them. 显然他无法区别两者的不同。

I arrived late but luckily the meeting had been delayed. 我迟到了，幸而会议推迟了。

但有些句子副词也可以出现句中。

eg：He smiled nastily. He evidently knew something I didn't. 他发出狞笑，他显然知道一些我所不知道的事。

有的句子也可用作其他种类的副词，不过这往往会导致位置和语义的变化：Clearly he didn't say so. 显然他没有这样说。

(句子副词)He didn't say so clearly. 他说得没有那么清楚。

(方式副词)(2)起连词作用的副词连接副词就是连接词，如besides，meanwhile，then, therefore, thus, However,Otherwise, so, yet 等。

作用以及位置：常放在两个句子中间，前面为逗号，后面放连接词，从句之前。

注意：so 也可放在形容词之前做修饰，yet 可放句尾或从句之前。
