高三英语第一轮语法复习教案-状语从句
状语从句
一．状语从句的定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。状语从句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。
状语从句一般分为九大类
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比较状语从句让步状语从句
二．状语从句的分类：
1．时间状语从句：
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。可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下：
（1）表示同时性，即主从句的谓语动作同时发生或几乎同时发生。
其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, once（一旦……）as soon as（一……就……）, the time（当……的时刻）, the moment （当……的时刻）,
by the time（到……时候为止）, next time(下次), the first time(第一次……的时候), the last time(上次……的时候)，immediately（一……就……）, instantly（一……就……）,directly（一……就……）以下关联词引起的句子中，前面常用过去完成时，后面用一般过去时hardly /scarcely…when…（刚……就……）, no sooner…than…（刚……就……）
Strike while the iron is hot.趁热打铁。
While I am washing the floor, you can be cleaning the windows.（while含有对比的意思）
我洗地板的时候，你可以擦窗户。
As / When I came home, I met an old schoolmate of mine.我回家的时候遇到了我的一位老同学。
I'll ring you up as soon as I get an answer from him.我一有他的答复就给你打电话。
Once you see him, you will never forget him. 你一旦见过他，就不会忘了他的。Hardly had we got into the country when it began to rain. 我们一到乡下就开始下雨了。
= We had hardly got into the country when it began to rain.
No sooner had he come home than she started complaining. 他一到家她就开始抱怨。
= He had no sooner come home than she started complaining.
He made for the door directly he heard the knock. 他一听到敲门声就向门口走去。
She rushed into the room immediately / the moment she heard the noise.她一听到声音就冲进房间
He left me a good impression the first time I met him.我第一次见他时，他给我留下了好印象。
He had no sooner arrived there than he fell ill.他刚到达那里就生起病来。
He had hardly finished when someone rose to refute his points.他还没说完就有人起来反驳他的论点
She had scarcely fallen asleep when a knock at the door awakened her.她刚要睡着，忽然敲门的声音把她惊醒。
★as、when、while用法一览表
类别作用例句
asas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。如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为"一边......，一边......"She came up as I was cooking.(同时)
The runners started as the gun went off.(几乎同时)
He looked behind from to time as he went.
他一边走，一边不时地往后看。
As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。
when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。如果表示从句的动作在主句的动作"之前"或"之后"发生时，多用when（=after）, 不用as或while。此外，when还含有"at that moment"的意思（= and then），引起的句子不能放在句首，也不能用as, while来替换。It was raining when we arrived.(指时间点)
When we were at school, we went to the library every day.(在一段时间内)
We were watching TV when suddenly the lights went out.我们正在看电视，这时灯突然灭了。
They had just arrived home when it began to
rain.他们刚到家，这时天就开始下雨了。
whilewhile意思是"当……的时候"或"在某一段时间里"。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。
当主从句之间表示转折或对比关系时，多用while, 不用as或whenPlease don't talk so loud while others are working.
He fell asleep while/when reading. Strike while the iron is hot.(用as或when 不可，这里的while意思是"趁……")
She thought I was talking about her daughter, while in fact, I was talking about my daughter.她以为我在谈论她女儿，而事实上，我在谈论我的女儿。
（2）表示先时或后时，即主句的谓语动作发生在从句之前或之后。
主要连词有：after（在……之后，before（在……之前）, when(=after)等。如：After / When the children had gone to bed, she began to prepare her lessons. 孩子睡觉了以后她开始备课。（从句的动作发生在主句的动作之前，所以从句用了过去完成时）
He had learned English for three years before he went to London. 他去伦敦之前已学了三年英语。
（主句的动作发生在从句的动作之前，所以主句用了过去完成时）
常用句型：It is/was/will be …before… 要过多久才…
It will be another five days before we finish this task. 还要再过5天我们才能完成这个任务。
It isn't/ wasn't/won't be … before… 没有过多久就…
It was not long before I forgot it all. 我没有过多久就全忘了。
He ran off before I could stop him.（主句和从句的动作几乎同时发生，时态一致）
我还没来得及阻止他他就跑掉了。(注意before在汉语中的译义)
（3）表示习惯性、经常性，即从句描述的不是一次性动作，而是经常发生的习惯性动作。
主要连词有every time（每次）, each time（每次）, whenever（每当）等。Whenever we met with difficulties, they came to help us.每当我们遇上困难的时候他们就来帮我们
Each time he came to town he would visit our school.他每次进城，总要来看看我们的学校。
Every time I went to his house, he was out.我每次去他家，他都出去了。
(4）表示持续性或瞬间性
主要连词有：since（自从）,ever since（自从）,until（直到……才/为止,till（直到……才/为止）
常用句型: It is /was…since…
It is just a week since we arrived here.我们到这儿刚刚一星期。
(主句的动作或状态持续时间较短，不能用ever since)
You have been reading to me ever since James went out. 自从James走后你一直在给我朗读。
(ever 放在since之前是用来表示说话者强调主句动作或状态持续时间长)
The big clock which used to strike the hours day and night was damaged during the war and has been silent ever since.( ever since可以放在句末，since则不能)
这只一向日夜不停打点报时的大钟在战争中损坏了，从此就一直不响了。
My uncle went to Tibet in 1951. He has been living there ever since.我叔叔于1951年去了西藏，从那以后他一直生活在那里。
Things went well until / till one night an accident happened.事情一切正常直到一天晚上发生意外
I knew nothing about it until / till he told me. 他告诉我了我才知道。
★until与till及not…until / till的用法
①until和till都可表示"直到．．．．．．为止"，与持续性动词的肯定式连用。如：
He waited until / till we finished our meal.他一直等到我们吃完饭。
②当until和till表示"直到．．．．．．才．．．．．．"时，通常与短暂动词的否定式连用，这时，until和till也可用before代替。如：
I didn't leave until / till / before she came back.直到她回来，我才离开的。
③be动词的肯定式和否定式都可以和until或till连用。
④until引导的从句可以放在主句之前或主句之后，但till从句一般不放在句首。如：
Until he told me, I knew nothing about it.他告诉我了我才知道。
当not until位于句首时，主句中的主语、谓语要使用倒装语序：
Not until she came back did I leave. = I didn't leave until she came back.
在强调句型中一般用until，不用till。如：
It was not until she took off her dark glasses that I realized she was a famous film star.
2．地点状语从句
地点状语从句是由where（在……的地方）, wherever（无论哪里）引导的：Wuhan lies where the Yangtze and the Han River meet.武汉位于长江和汉水汇合处。
Where there is a will, there is a way.有志者，事竟成。
You'd better make a mark where you have any questions.(这里where引导的从句不是定语从句)
哪儿有问题，你最好在哪儿做个记号。
He would keep in touch with us wherever he was.他无论在什么地方，总是与我们保持联系。
3．原因状语从句
表示原因的状语从句可以由as（由于）,because(因为), since（既然）,now (that) (既然), for (由于)considering that（顾及到）, seeing that（由于）等连词引导：I do it because I like it.因为我喜欢我才干。(because不能与so连用)
He couldn't have seen me, because I was not there.他不可能见过我，因为当时我不在那儿。
Seeing (that) quite a few people were absent, we decided to put the meeting off.由于好些人都没到会，我们决定延期开会
Now that/Since you are all here, let's try and reach a decision.既然大家都来了咱们就设法做一个决定吧
As she was ill, she didn't come to the party.由于病了，她没来参加晚会。Considering that they are just beginners, they are doing quite a good job.考虑到他们才刚刚学做，他们干得算很不错的了。
★because, as, for , since 的区别
类别用法例句
becausebecause语气最强表示不知道的原因时用because,即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。下列情况下只能使用because:
①在回答why的问句时；②在用于强调句型时；
③被not所否定时。You want to know why I'm leaving? I'm leaving because I'm full.
forfor的语气不及because, since, as强，为并列连词，引导的分句常放在主句之后，从句前通常用逗号，表示说话者为所做的推断和预测提供理由，或对前一分句进行补充和解释。如果不是因果关系，而是对前面主句的内容加以解释或推断
时，只能用for。It's morning now, for the birds are singing.（很显然，鸟叫不可能是"现在已是早上"的原因。）
as/since表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前，但有时却相反。Seeing all of the children already seated, he said,"Since everyone is here, let's start."
4．目的状语从句
引导目的状语从句的主要连词有: so that（以便）, in order that（为了）, for fear that（以便）,目的状语从句的谓语动词常与情态动词can, could, may, might, should连用
Let's take the front seats (so) that we may see more clearly.我们坐前排吧，这样我们看得更清楚些。
School was closed early in order that the children might go home ahead of the storm.
早点儿放学是为了让孩子们在暴风雨到来之前回家。
He took the name down for fear that he should forget it.
他把名字写下省得忘了。（该从句中一般用情态动词should+动词原形，或省略should）
Better take more clothes in case the weather is cold.最好多带些衣服以防天气会冷。
5．结果状语从句
引导结果状语从句的连词有：that, so that（从句中不带情态动词）, so…that(如此……以致……),
such…that(如此……以致……)等。
What has happened that you all look so excited? 发生了什么事，使你们都显得如此兴奋？
He didn't plan his time well, so that/so he didn't finish the work in time.
他没把时间计划好，结果没按时完成这项工作。
We left in such a hurry that we forgot to lock the door. 我们走得匆忙，把门都忘了锁了。
The village is so small that it cannot be shown in the map.这村子太小，所以这地图上没有。
Jenny is such a clever girl that all the teachers like her very much
= Jenny is so clever a girl that all the teachers like her very much
Jenny是如此聪明的女孩，以至老师们都非常喜欢她。
注意：so + 形容词/副词+ that从句；such +名词+ that从句。
但是，当名词前有many, much, few, little(少)修饰时，要用so,不能用such。
I have had so many falls that I am black and blue all over.我摔了许多跤，以至于浑身青一块紫一块
He has so few friends that he often feels lonely.他朋友很少，所以经常感到孤独。
I had so little money then that I couldn't afford a little present.我当时囊中羞涩连一份小小礼物都买不起
6．条件状语从句
表示条件的状语从句可以由if（如果）,unless（除非）, in case（万一）, so /as long as（只要）, as/ so far as（就……而言）, on condition that（条件是……）suppose（假设）supposing（假设）（仅用在问句中）等词或词组引导。一般情况下当主句是将来时的时候，从句要用一般现在时。
As/So long as we don't lose heart, we'll find a way to overcome the difficulty.
只要我们不灰心，我们就能找到克服困难的方法。
Send us a message in case you have any difficulty.万一你有什么困难，请给我们一个信儿。
If you leave at 6 o'clock tomorrow morning, you'd better get to bed now.
如果你明早6点钟走，你最好现在就上床。

只要你能保持整洁，我们可以让你使用这个房间。
As/So far as I know, he is an expert on DNA.据我所知，他是一个DNA专家。He'll accept the job unless the salary is too low/ if the salary is not too low.
他会接受这项工作的，除非薪水太少/如果薪水不太少的话。
Suppose/Supposing we can't get enough food, what shall we do?
假设我们弄不到足够的食物，那我们怎么办？

Leave things as they are.让一切顺其自然。

常见句型：the +比较级，the +比较级

9．让步状语从句
让步状语从句由although（尽管）, though（尽管）, however（无论怎样）,whatever （无论什么）, whoever（无论谁）, whomever（无论谁）, whichever（无论哪个）,whenever（无论何时）, wherever（无论哪里）, whether（是否）, no matter (who, what, where, when) （无论……）, even if（即使）, even though（即使）等词引导。
We won't be discouraged even if(=even though) we fail ten times.我们就是失败十次也不泄气。
It was an exciting game, though / although no goals were scored.

Don't let them in, whoever(=no matter who) they are.不管他们是谁，别让他们进来。
No matter what I say or how I say it, he always thinks I'm wrong.无论我说什么或怎么说，他总认为是我错。
连词as也可以引导让步状语从句，但从句中要用特殊语序。如：
Young as he is, he knows a lot=Though he is young 或Young though he is, he….他虽然年轻，但懂得很多。(though 也有这种用法，可以替换as,但although没有这种用法)
though还可以用作副词，放在句末。如：
It was hard work;; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦但是我喜欢干
一般情况下，unless相当于if…no t，可以互换。如：
I won't let you in unless you show me your pass = I won't let you in if you don't show me your pass.如果你不出示通行证，我就不让你进来。
10．省略现象
有些表示时间、地点、条件、方式或让步等的状语从句中，如果谓语含有动词be，主语又和主句中的主语一致，或者主语是it，常把从句中的主语和谓语的一部分（特别是动词be）省略掉。注意状语从句中从句的省略现象
（1）连接词+ 过去分词
Don't speak until spoken to.= Don't speak until you are spoken to.
Pressure can be increased when needed.= Pressure can be increased when it is needed

高三英语第一轮语法复习教案-状语从句
状语从句 一．状语从句的定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。状语从句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。 状语从句一般分为九大类 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比较状语从句让步状语从句 二．状语从句的分类： 1．时间状语从句： 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。可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下： （1）表示同时性，即主从句的谓语动作同时发生或几乎同时发生。 其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, once（一旦……）as soon as（一……就……）, the time（当……的时刻）, the moment （当……的时刻）, by the time（到……时候为止）, next time(下次), the first time(第一次……的时候), the last time(上次……的时候)，immediately（一……就……）, instantly（一……就……）,directly（一……就……）以下关联词引起的句子中，前面常用过去完成时，后面用一般过去时hardly /scarcely…when…（刚……就……）, no sooner…than…（刚……就……） Strike while the iron is hot.趁热打铁。 While I am washing the floor, you can be cleaning the windows.（while含有对比的意思） 我洗地板的时候，你可以擦窗户。 As / When I came home, I met an old schoolmate of mine.我回家的时候遇到了我的一位老同学。 I'll ring you up as soon as I get an answer from him.我一有他的答复就给你打电话。 Once you see him, you will never forget him. 你一旦见过他，就不会忘了他的。Hardly had we got into the country when it began to rain. 我们一到乡下就开始下雨了。 = We had hardly got into the country when it began to rain. No sooner had he come home than she started complaining. 他一到家她就开始抱怨。 = He had no sooner come home than she started complaining. He made for the door directly he heard the knock. 他一听到敲门声就向门口走去。 She rushed into the room immediately / the moment she heard the noise.她一听到声音就冲进房间 He left me a good impression the first time I met him.我第一次见他时，他给我留下了好印象。

【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 when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 heard the news，they all jumped with joy. I owed Jack $ 100 when I was in London. 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。延续性动词 非延续性 动词 随着…… 一边……； 一边…… 当……时候 The students sang as they walked. As he stood up，he dropped the glass， breaking it into pieces. while 从句的动作与主句 的动作同时发生，强调 一段时间。从句中常用 过去进行时态或一般 过去时态。延续性动词当……时候 在……期间 While I was reading， he came in. I made some foreign friends while I was in London. 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式：sb. was doing sth. when...某人正在干某事就在这时…… sb. was about to/ going to do sth. when...某人正打算干某事就在这时……

状语从句 （一）时间状语从句 时间状语从句 1．when, while, as的区别 这三个词都可以用作连接词，表示时间关系，但有所区别。 (1)when表示时间关系时，意思常常是“当(在)……的时候”。主句和从句中的动作或事情可以同时发生，也可以先后发生。例如： When we were at school, we went to the library every day. 我们在求学的时候，每天都到图书馆去。 (2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。如上面第一个例句中的when，可以用while代替；而第二个例句中的when，就不能用while代替。例如： Please don’t talk so aloud while others are working. 别人在工作的时候，请勿大声讲话。 (3)as用作连接词表示时间关系时，意思也是“当(在)……时候”，往往可与when 或while通用，但它着重指主句和从句中的动作或事情相并发生。例如： I saw him as he was getting off the bus.当他下公共汽车的时候，我看见了他。2．一些表示时间的名词短语也可用来引导时间状语从句 the minute, the moment, the instant, every time, the last time, every time。如：

1.状语从句概念？ 状语从句指句子用作状语时，起副词作用的句子。状语从句在高考中考察基本是以翻译从句引导词为主。 2.分类以及各个从属连词用法？ 2.1时间状语从句(when，while，as, no t…until, since,before……) when，while，as 区别：while用引导的动作必须是持续的，侧重于主句动作和从句动作相对比 e.g I was cooking at noon while she was sleeping. as“一边…一边…”或着“随着” e.g He was looking behind as he walked. As times flies, the weather is getting cooler and cooler 当主句表达短暂性动作，而从句表示一段时间内的延续性动作时，.用三者都可以 I met Jim when/while/as I was riding in Heping Road. 其他：as soon as, immediately, directly, the moment, the instant, once(一…就…) The boy burst into tears immediately he saw his mom. I will leave here as soon as I get my visa.(主将从现：if/as soon as/when/until 引导的时间状语从句) no sooner…than…; hardly…when…; scarcely…when…(一…就…, 但含有否定意味的词置于句首时，主句要部分倒装) (hardly…before…; scarcely…before…)主句用过去完成时，从句用一般过去时。 I had hardly got home when it began to rain. Hadly had I got home when it began to rain. No sooner had we reached at school than the bell went. till/untill(直到till不可以用于句首), not…until（直到…才…） 注意not until强调句用法和倒装句用法。 It was not until you told me that I realized the importance.

语法复习六：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。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。 （一）时间状语从句 表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。 e.g. When I came into the office, the teachers were having a meeting. He started as soon as he received the news. Once you see him, you will never forget him. No sooner had I gone to bed than I went to sleep. （二）原因状语从句 原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because 强。 e.g. He is disappointed because he didn't get the position. As it is raining, I will not go out. Now that you mention it, I do remember. （三）地点状语从句 引导地点状语从句的连词是where 和wherever等。 e.g. Sit wherever you like. Make a mark where you have a question. （四）目的状语从句 引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。 e.g. Speak clearly, so that they may understand you. She has bought the book in order that she could follow the TV lessons. He left early in case he should miss the train. （五）结果状语从句

专题八 状语从句、定语从句 状语从句 一、时间状语从句 1．before 引导的从句中不用否定式谓语。常用如下句型： It is long before...(过了好久才……) It is not long before...(过了不久就……) 2．since 后面所用动词不同，该动词所表示动作持续时间的计算方法也不同。 ⎩ ⎪⎨ ⎪⎧ since ＋瞬间动词过去式从该动作发生时算起since ＋持续性动词过去式从动作结束时算起 It is two years since he joined the army. It is two years since he smoked. 二、地点状语从句 多由where 和wherever 引导。 Where there is a will ，there is a way. 二、原因状语从句 在表示原因时，because 语气最重，其次是as ，since ，now that ，故在回答why 问句或者在强调句对原因进行强调时，只能用because 。for 是并列连词，表示推测的理由或者进一步说明，不能放在句首，for 前要用逗号。 —Why were you absent? —Because I was ill. 三、目的状语从句 1．so that/in order that 引导的目的状语从句中的谓语动词多用can/could/may/might/will/would ＋动词。 Please turn off the light so that I can go to sleep. 2．for fear that ，in case ，lest 表示“以防，免得”。 He is working hard for fear that he should fail. 四、条件状语从句 1．providing/provided (that)假如，假若 Providing (that) no one has further questions ，the meeting will be over. 2．on the understanding that ＝on condition that 在……条件下 I give you money on the understanding that you finish your homework. 五、结果状语从句 注意such 引导的结果状语从句与定语从句的区别。 试比较： This is such an interesting book that everyone likes to read it. This is such an interesting book as everyone likes to read. 六、目的状语从句与结果状语从句的区别 in order that 可放在句首，只能引导目的状语从句；so that 引导目的或结果状语从句，不能放在句首。 试比较： He spoke so slowly that we all followed him.(结果状语从句)＝He spoke slowly ，so we all followed him. He spoke slowly so (in order) that we could all understand him.(目的状语从句) 七、让步状语从句 1．as 引导让步状语从句，作“尽管”解，用倒装句，语序为：状语/宾语/表语/动词原形＋as ＋主语＋谓语……。如果句首是单数可数名词作表语，名词前无冠词。 Clever as you may be ，you can’t do that. Clever boy as he is ，he can’t solve the problem. 2．while 有时引导让步状语从句，作“尽管”、“虽然”讲，多用于句首。 While I admit the problems are difficult ，I don’t agree that I can’t solve them. 八、地点状语从句 多由where 和wherever 引导。 Where there is a will ，there is a way. 九、方式状语从句 方式状语从句常由as(按照)，just as(正像)，as if ＝as though(仿佛，好像；从句可用虚拟语气)等引导。 I changed my mind as you suggested. 定语从句 一、关系代词的用法 1．that 和which 的用法 (1)限制性定语从句中，必须用关系代词that 的情况： ①当先行词是不定代词all ，much ，little ，something ，everything ，anything ，nothing ，none ，the one 时。 You should hand in all that you have. ②当先行词前面被the only ，the very ，any ，few ，little ，no ，all 等词修饰时。
