一、时间状从中连接词when的用法小结：
1、when引导的时间状从的谓语动词可以是可延续的，也可以是表短暂性的动词，可用于主句和从句动作同时发生或从句动作先于主句动作。例：
When the film ended,the people went back.
When I lived there,I used to go to the seashore on Sundays.
2、可用作并列连词，其意义是“那时，这时”，相当于and at this\that
time.常用于以下句式：
was about to do sth. … when…\
be (on the point of) doing sth. …when…(刚要…这时突然…)
e.g.I was about to stop pretending to being listening to the class to listen to
what the teachers said when Mr. Li shouted at me so loudly that the whole class can hear.
3、还可以表示原因“既然”，相当于since,considering that.如：

______I accept that he is not perfect,I do actually like the person.
A\While B\Since C\Before D\Unless
二、时间状从中连接词while 的用法小结：
1、while 引导的动作必须是持续性的，强调某一段时间内，主从句动作同时发生，或主从句中的动作或事物在从句中的动作或事情的进展过程中发生。如：
Please don’t talk so loud while others are working.
2、while作为并列连词，意为“然而，却”，表示对比。

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,is 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.
四、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是可持续的，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 rest.
3、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.
五、其他引导时间状语从句的连接词：
1、一些词，如the
moment\minute\instant,immediately,directly,instantly,hardly…when,no sooner…than等，也可因的一个时间状语从句，相当于as soon as的意思。如：
e.g.We will come across this situation the moment (when)your most important relatives leave you.
It is not wise that we stop our lesson immediately (when) the bell rings if we can’t finish our task.
2、一些含有time 的名词短语，如every\each\next time,by the time 等，以及the day\year,the morning等也可以引导一个时间状语从句。如：
e.g.So many thousands of people died everytime there was an outbreak.
The day he returned home,his father was already dead.
Next time you come ,please bring your ID card.
3、如果hardly 或no sooner或scarcely置于句首，句子必须用部分倒装结构。如：

has never praised him_______he became one of the top students in
the class.

A\when B\unless C\after D\until
It was not ______she took off her dark glasses ______I realized she
was a famous film star.
A\when;that B\until;that C\until;when D\when;then
六、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”。
You may stay here until the rain stops.
2、用于否定句时，主句谓语动词时非延续性动词，从句为肯定，意
为“直到…才”，如：
He wouldn’t go to bed till/until he had finished the work.
3、until 可以置于句首，till不行。如：
Until you told me , I had no idea for it.
4、not…untill句型中的强调和倒装说法：
It is\was not until that…
Not until+从句+助动词+主句。例：
e.g.it was not until you told me that I had some idea for it.
Not until you told me did I hace any idea for it.
七、连接词before的小结：
1、词义：
The American Civil War lasted four years before the North won in the end. (在…之后，才…)
He rushed out of the room before I could say a word.(…还没来得及，就…) It was evening before we reached the little town of Winster.(在…之前就…) He make a mistake,but then he corrected the situation before it got worse.(没等…就…)
2、其他句型：
1、it+（will/would）be +时间段+before… “过了（多长时间）才…”
It will be some time before we know whether the drug takes effect or not.
It was quite a few years before he finally finished the novel.
2、it+（will/would）be not +时间段+before… “过不了多久就…”
It will be not long before a helicopter arrived on the scene to rescue the surviors of the air crash.
It wasn’t 2 years before you go to join in the final examination.
3、it+be+时间点+before… “…发生时，是…(时间)”
It was not yet 8:00 before he arrived home
.八、连接词since的用法：
注：since的用法主要有两点：一是表示“自从…以来”，二是表示“既然”。
1、若since 引导的状语从句的谓语动词是终止性的过去时，则从
句表示的时间是“从动作开始的那一刻起”。如：
He has studied very hard since he came to our school.
We have been missing them since they left here.
2、若since 引导的状语从句的谓语动词是持续性动词或表示状态
的动词的过去时时，则从句表示的时间是“从持续动作或状态
结束时算起”。如：
I haven’t heard any noise since I slept. Sleep为持续性动词，sleep的动作结束时，即“醒来”时，译为“我醒后还未听到任何声响。”
John is now with his parents in New York .It is already 3 years since he was a teacher.
3、若since 引导的状语从句的谓语动词是持续性动词的现在完成
时则表示动作和状态延续到现在（说话时），其表示的时间
的起点应从动作之时算起。如：
I haven’t heard from him since he has lived there.这里的has lived表示动作的持续性，时间的起点应从“开始居住”时算起，“自从他（开始）住在
那儿，我就一直没有收到他的来信”
Since we have owned a car,we have gone camping every year.
4、句型it is +一段时间+since…与it has been +一段时间+since…意
思相同，时间的计算从since从句的动作完成或状态结束时算
起。但是，在该句型中，since从句中同样存在着谓语动词的
终止性和延续性的区别。例：
It is 2 years since he left the country.
It is 3 years since the Whites were in London.
It is 5 years since the boy became a young pioneer.(____)
It is 5 years since the boy was a young pioneer.(____)

A\as long as B\while C\IF D\even though
It is known to all that ___you exercise regularly,you won’t keep good health.
A\unless B\whenever C\although D\if
1、unless=if not,意思是“除非”、“如果不…就…”.
_____i can see,there is one possible way yo keep away from the danger.
A\as long as B\As far as C\Just as D\Even if
I always take something to read when I go to the doctor’s ___I have to wait.
A\in case B\so that C\in order D\as if
2、As long as（只要）和 as far as（就…而论）都可引导条件状
语从句。

问题6：
_______I accept that he is not perfect,I do actually like the person.
A\While B\Since C\Before D\Unless

A\however B\whatever C\whichever D\although

A\however B\whatever C\whichever D\wherever
注：as 引导的让步状语从句常见的几种倒装方式：
1、若从句谓语部分为“vi.+adv.”,常将从句的副词提前到从句句
首。
Hard as you may try,you will not succeed.
2、若从句谓语部分为|“情态动词+vi.”,常将形容词提前到从句句
首。
Wait as you may,he will not see you.
3、若从句谓语部分为“系动词+n.”，常将这个表语名词提前，但
这个名词前面的不定冠词要省略。
Child as he is ,he can tell right from wrong.
时间状语从句 要点: 时间状语从句，由以下连词引导： when while as after before as soon as since till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。 当。。。的时候 mozart started writing music when he was four years old. (当)莫扎特的时候，开始写音乐作品。 当。。。时 he visited a lot of places while he was traveling.他在旅途中参观了许多地方。 在。。。的同时；一边。。。一边。。。 he smiled as he stood up.他一边站起来一边笑着。 在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家。 在。。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 soon as 一。。。就。。。(主将从现) we began to work as soon as we got there.我们一到那就开始工作。 i will write to you as soon as i get home.我一到家就给你写信。 自。。。以来到现在 表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来，他就在这所学校教书。 (还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。) 8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 they walked till /until it was dark.他们一直走到天黑。 xiao ming didn’t leave home till / until his father came back.小明直到他爸爸回来才离开家。 9. by the time 到。。。为止 (所在句子的主句应用完成时) by the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。 by the time i got to school, the class had already began.我到校时，已经开始上课了。 难点——as when while的辨析 as when while都表示主、从句动作同时发生，三者差异如下： as 表示“一边。。。一边＂的意思 强调两个动作同时进行，并表示对比时 when 1、还可以表示从句动词的动作在主几句动词的动作＂之前＂或＂之后＂发生。 2、when＝and then; at that moment (正在那个时候)

初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。

一、方式状语从句 1、方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如： Please do as what I told you.请按照我告诉你的做。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： He looks as if (as though) he had been hit by lightning. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He cleared his throat as if to say something. 他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger. 波涛冲击着岩石，好像很愤怒。 2、其他的引导词 1）the way：Please pronounce the word the way I do.请照我这样,读这个单词. 2）口语常用的like：He sit there smiling like it was his birthday.他面带微笑坐在那儿,像是过生日似的. （这里用了虚拟语气，值得注意的是be动词用的was，而表示虚拟as if引导的be动词则只能是were。） 地点状语从句表示地点、方位，这类从句通常由where，wherever引导。例如： Where there is a will, there is a way. 有志者，事竟成。 They will go where they are happy. 他们想到他们觉得快乐的地方去。 二、地点状语从句 1、地点状语从句类型 1）Where＋地点从句。此句型通常译成“哪里……哪里就……”或“····的地方”。例如：Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。 They were good persons. Where they went, they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。 You should have put the book where you found it. 你本来应该把书放回原来的地方。We must camp where we can get water. 我们必须在能找到水的地方露营。 2）Anywhere/ wherever＋地点从句，＋主句。 anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere 引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。例如： Wherever the sea is , you will find seamen.有海就有海员。 2、地点状语从句与定语从句的区别 二者区别在于分句在句中作什么成分。作状语，则是状语从句；作定语修饰名词，则是定语从句。where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语
2015-12-20 条件状语从句 1、定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后(状语从句中的动作)，其它事情(主句中的动作)才能发生，通常译作"假如"。(注意:在含有条件状语从句的复合句中，表示将来时态，主句是态,或谓语动词是，从句要用态,即[原则]。 Eg1: Take the medicine, you will be fine. Eg2: If you can read as many English books as possible, your English will be improved. 2、用法 语法引导条件状语从句最常用的连词是if, 由if引导的条件状语从句表示在某种条件下某事很可能发生if引导的条件状语从句既可以将从句放前面也可以将从句放后面。除了if 之外，还有其他连词也可以引导条件状语从句。 【注：在条件状语从句中，绝大数情况下some要变为any。】 (1) unless conj.除非，若不，除非在……的时候 Eg1: You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能那儿。 Eg2: Unless it rains, the game will be played.除非下雨，比赛将照常进行。 (2) on condition(that)...在……条件下，如果on condition (that)...引导的是主句事件发生的前提条件或唯一条件。 Eg1: I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相，条件是你答应保密。 Eg2: You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 Attention（注意）： ①unless = if...not.
