从句讲解
定语从句
一。I 关系代词引导的定语从句
 关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。
1)who, whom, that
  这些词代替的先行词是人的名词或代词,在从句中作主语和宾语。例如:
Is he the man who/that wants to see you? 他就是你想见的人吗?(who/that在从句中作主语)
He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom/that在从句中作宾语)
2) whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换)。例如:
 They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。
3)which, that所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等。例如:
  A prosperity which / that had never been seen before appears in the countryside.
农村出现了前所未有的繁荣。(which / that在句中作宾语)
 The package (which / that)you are carrying is about to come unwrapped. 你拿的包快散了。
(which / that在句中作宾语)
II. 关系副词引导的定语从句
  关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。
1)关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用。
  There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
  Beijing is the place where(in which) I was born. 北京是我的出生地。
  Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?
2)that代替关系副词,可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略。例如:
  His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。
  He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。
III.判断关系代词与关系副词
  方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。例如:
  This is the mountain village where I stayed last year. 这是我去年呆过的山村。
  I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。
  判断改错:
  (错) This is the mountain village where I visited last year.
  (错) I will never forget the days when I spent in the countryside.
  (对) This is the mountain village (which) I visited last year.
  (对) I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。
  方法二: 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词。
例1. Is this museum ___ you visited a few days age? A. where B. that  C. on which  D. the one
例2. Is this the museum ____ the exhibition was held. A. where B. that  C. on which D. the one
答案:例1 D,例2 A
例1变为肯定句: This museum is ___ you visited a few days ago.
例2变为肯定句: This is the museum ___ the exhibition was held.
  在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D。
  而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语。而此题中,介词on 用的不对,所以选A。
  关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词(who, whom, that, which, whose); 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) 。
IV. 限制性和非限制性定语从句
1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开。例如:
   This is the house which we bought last month. 这是我们上个月买的那幢房子。(限制性)
   The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的。(非限制性)
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。例如:
Charles Smith, who was my former teacher, retired last year. 查理•史密斯去年退休了,他曾经是我的老师。
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
  This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。例如:
He seems not to have grasped what I meant, which greatly upsets me.他似乎没抓住我的意思,这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。
V. 介词+关系词
1)介词后面的关系词不能省略。
2)that前不能有介词。
3)某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
  This is the house in which I lived two years ago. 这是我两年前住过的房子。
  This is the house where I lived two years ago.
 Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?
  Do you remember the day when you joined our club?
二。定语从句应注意问题
I。that, which区别
关系代词that的几种情况。
1. 先行词为all, everything, nothing, something, anything, little, few, much等不定代词时。先行词被all, each, few, much, every, no, some, any等不定代词修饰时。如: There is little that I can use. 几乎没有什么我能用的了。
All the books that you need are here. 你所需要的书都在这儿。
2.先行词被序数词或形容词最高级修饰时。如:
This is the first composition that he has written in English.这是他用英语写的第一篇作文。
4.先行词既有人又有物时。如:
He talked about the teachers and schools that he had visited. 他谈到了他曾拜访过的老师和学校。
5.主句是以who或which开头的疑问句时。如:
Who is the man that is speaking over there? 在那里说话的人是谁?
6.先行词被the only,the very, the last等修饰时。如:
This is the very gun that I am looking for. 这正是我在找的枪。
7. 关系代词在从句中作表语时。如:
He is not the young man that he was thirty years ago.他已不是三十年前的那个年轻人了。
关系代词which
(1)在引导非限定性定语从句时(不能放句首)
He can speak English fluently,which impressed me most.他的英语讲得很流利,给我留下了深刻印象。
(2) 介词后
This is the house in which I have lived for 2 years.这就是我居住了两年的房子。
(3)在非限制性定语从句中,即可指一个词,也可指整个句子。
She married again, which was unexpected.
I lost my watch, which is not found yet.
II。which, as 区别
as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:
 (1) as 引导的定语从句可置于句首,而which不可。
  As we know, smoking is harmful to one's health.
(2)the same… as;such…as 中的as 是一种固定结构, 和……一样……。
   I have got into the same trouble as he (has).
III。介词+关系代词
介词+whom(人)主,谓结构
介词+which(物)主,谓结构
(介词)+whose+名词+主,谓结构=and+介词+形容词形物主代词+名词+主谓结构
(介词)+which+名词+主,谓结构=and+介词+this或that +名词+主谓结构
He is the person to whom you can turn for help.
The pencil with which he was writing broke.
He is the man from whose house (=and from his house) the picture were stolen.
We traveled together to Paris, at which place(=and at this place) we parted company.
IV.分隔式定语从句
有些定语从句和现行词之间插入一个词组,短语或别的成分,叫做分隔式定语从句
He arrived Hangzhou in 1984, where he became manager 2 years later.
名词性从句
主语从句:应注意问题
1. 主语从句的语序
主语从句要求使用陈述句语序,而非一般疑问句语序。如:
What surprised me most was that the little girl could play the violin so well.
How he was successful is still a puzzle.
2. 连接词的选用
(1)that和what的选用
that和what都可引导主语从句。what除起连接作用外,还在名词性从句中充当某些成分,可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分,无词义,只起连接词作用。
What he wants is a book. That light travels in straight lines is known to all.
(2)if和whether的选用
引导主语从句,不能用if,只能用whether。如:
Whether we will hold a party in the open air tomorrow depends on the weather.
(3)其它连接代词和副词的选用
根据主语从句的具体意义,正确的选择who, which, when, where, why, how等连接词,这些连接词既有疑问含义,又起连接作用,同时在从句中充当各种成分。如:
When we shall hold our sports meet is not decided. Who broke the glass yesterday is not clear.
(4)whatever / whoever的功用
whatever, whoever在主语从句中不含疑问意义。它引导主语从句,并在从句中作主语、宾语、表语等。whatever = anything that; whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别
Whoever breaks the law should be punished. (主语从句)(=Anyone who breaks the law should be punished. )
Whoever breaks the law, he should be punished. (让步状语从句)(=No matter who breaks the law, he should be punished. )
3. it构成的主语从句
(1)由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语。
It is well-known that the earth moves around the sun.
需要注意的是,it作形式主语代替主语从句时,要注意和as引导的定语从句的区别。试比较:
It was reported that the US was under the terrorist attack. (主语从句,有that,无逗号)
As was reported, the US was under the terrorist attack.
(定语从句,无that,有逗号)
(2)常见用it作形式主语的复合句结构
It is a fact (a good idea / a pity / a shame / no wonder / good news…)that…如:
It”s a pity that you missed the film.
你没有看那部电影真是太遗憾了。
It is necessary (clear / true / strange/ important / possible…)that…
需要注意的是,这类主语从句中,谓语动词很多为“(should)+动词原形”,即要用虚拟语气。
It is necessary that you (should)master the computer.
It is important that a student learn English well.
It is reported (well-known / hoped / thought / expected /said /believed/decided /suggested /ordered…)that…如:
It is said that he was killed in the earthquake. 据说他在地震中丧生了。
It seems (happened / appears / doesn”t matter / makes no difference / …)that …
It seems that they will win the game.
看起来他们好像会赢得这场比赛。
It makes no difference whether he will attend the meeting or not.
他是否会参加会议都无关紧要。
4。主语从句连接词that不能省略 That he didn’t like her was obvious.
表语从句 
定义:
A 表语从句就是用一个句子作为表语。
The problem   is    puzzling.
  主语    连系动词  形容词作表语
The problem   is    when we can get a pay rise.
 主语    连系动词   一个句子作表语---表语从句
B 连接表语从句的连接词有:that, what, who, when, where, which, why,
  whether,how.
He has become a teacher.=He has become what he wanted to be ten years ago.
She has remained there for an hour.=She has remained where I stood yesterday for an hour.
His suggestion is good.=His suggestion is that we should stay calm.
The question is confusing.=The question is when he can arrive at the hotel.
         who will travel with me to Beijing tomorrow.
          why he cried yesterday.
          how I can persuade her to join us in the party.
          whether the enemy is marching towards us.
二 注意:
A 表语从句一定要用陈述语序。
False: The question is when can he arrive at the hotel.
Right: The question is when he can arrive at the hotel.
B 不可以用if,而用whether 连接表语从句(as if 例外)。
False: The question is if the enemy is marching towards us.
Right: The question is whether the enemy is marching towards us.
Right: It looked as if he had understood this question.
C 不像宾语从句,在有表语从句的复合句中,主句时态和从句时态可以不一致。
Right: The question is who will travel with me to Beijing tomorrow.
Right: The question is why he cried yesterday.
D that在表语从句中不可以省掉。
宾语从句 应注意问题
1. 引导词that的取舍
that引导宾语从句时,特别是在口语中 that常可省略。但在下列情况下,引导宾语从句的that一般不省略。
1)当由两个或两个以上的that引导的从句作同一个动词或介词的宾语时,第二个以及以后从句中的that不宜省略。如:
He said(that)he couldn't tell you right away and that you wouldn't understand.
2)当动词think, make,feel,consider等后用it作形式宾语来代替that引导的宾语从句时。
We think it necessary that we should practise spoken English every day.
3)当that引导的宾语从句中的状语紧接that时。如:
He said that even if it rained,he would be able to come.
2.引导词whether和if的选用
二者引导宾语从句时,一般可换用。但在下列情况下,通常只能用whether而不能用if。
1)在引导词后紧接or not时。如:
We didn't know whether or not she was ready.比较We didn't know whether/if she was ready or not.)
2)当用if易引起歧义时。如:
Please let me know whether you like it.(若该句用if,也可理解为:如果你喜欢它,请告诉我。)
3. 从句中谓语动词时态的选择
一般地说,当主句谓语动词使用的是过去的时态时,后面宾语从句中的时态要受主句时态的限制,用相应的过去时态。但若宾语从句所表示的是客观真理(规律)或人和物的经常性、习惯性以及阶段性的动作或事实时,则从句的时态不受主句时态的限制。这种情况下从句常用一般现在时。
When I was a boy,my teacher told me that the earth is round.
He told me he goes to the park every day.
4.从句中使用虚拟语气的场合
1)在表示建议(suggest),要求(demand,insist)和命令(order)等动词后的宾语从句中,常用“(should)+动词原形”的形式来表示虚拟语气。如:
I suggest that we(should)have a rest now.
2)表示愿望的wish后的宾语从句中须用虚拟语气。如:
I wish I could fly.(用过去式表示与现在事实相反的愿望)
I wish I had known it before.(用过去完成式表示过去未实现的愿望)
I wish you would stay a little longer.(用would或would +动词原形来表示将来的愿望)
5. 含宾语从句的疑难句型
1)I/We don't think +宾语从句
这是一个常见的否定转移句型。使用时常把宾语从句中的否定词not移至主句中,即主句谓语用否定式而从句谓语则用肯定式。该结构常译为“我(我们)认为……不……”。如:
We don't think there is anything of interest in your pictures. 2)疑问词(what,how,who等)+do you think +其它句子成分
这是一个复杂特殊疑问句。它由一个一般疑问句(do you think)和一个特殊疑问句(疑问词+其它句子成分)合并而成。如:
When do you think he will be back?你认为他会什么时候回来呢?
注:常用于上面两结构的主句动词除think外,还有believe,suppose,imagine等。
同位语从句
英语中有一些名词如fact, idea, news, word, hope, promise, suggestion, reply, problem, belief, doubt, truth, order, thought等,它们本身有一定的意义,但表达得不够具体。为了使其表达的意义更加具体明确,其后常跟有一个从句,用来补充说明该名词的内容,这个从句就叫做同位语从句。
The news that our team had won the match spread the whole country.
有时如果主句的谓语动词较短,为保持句子平衡,避免头重脚轻,同位语从句也常与要说明的分词分开。
Word came that he died yesterday.
一、同位语从句的引导词。
1. 表示陈述意义时通常用that。注意that不能省略。例如:
The fact that he didn”t pass the college entrance examination disappointed his parents.
The king made a promise that he would make anyone rich if one could cure his illness.
2. 当名词doubt用在否定句中时,其后的同位语从句应用that引导;而用在肯定句或疑问句中时则可以用其他词来引导。
I never have the doubt that you can look after yourself.
Some people have the doubt how such a little boy can lift so heavy a box.
3. 表示“是否”的意思时只能用whether,不能用if。这一点与主语从句相似。例如:
The question whether he can finish the work within two days remains unknown.
4. 表示疑问时也可用其他引导词。例如:
This student asked a good question why pollution can”t be stopped.
二、同位语从句与其他从句的比较。
1. 同谓语从句与主语从句和宾语从句的比较。
两者作用不同,主语从句和宾语从句都是从句在主句当中充当主语和宾语;而同位语从句是一个跟在某一名词后并具体说明该名词内容的从句。例如:
(1)That the pop singer will come to this city excited everybody.
(2)Everybody is excited to hear that the pop singer will come to this city.
(3)The news that the pop singer will come to this city excited everybody.
以上三个句子中(1)(2)两句分别在主句中充当主语和宾语。(1)句划线部分为主语从句,(2)句为宾语从句,而(3)句中划线部分则是具体说明名词news内容,故为同位语从句。另外还须注意的是,that引导主语从句、同位语从句时不能省,而引导宾语从句时通常可以省略。
2. 同位语从句与定语从句的比较。
(1)词类不同
同位语从句的名词只能是前面提到的几个有限的、有一定内涵的名词;而定语从句的先行词可以是名词、代词、主句的一部分或是整个主句。
(2)性质不同
定语从句是从句对其先行词的修饰或限制,属于形容词性从句的范畴;而同位语从句是从句对其前名词的解释,该名词与同位语从句的关系可以用“主系表”来表达。例如:
We have all heard the news that our team has won.
名词与其后的同位语从句可以表达为:
The news is that our team has won.
(3)引导词不完全相同。
有些引导词如:how, whether可以引导同位语从句,但不能引导定语从句。what不可以引导定语从句,但却可以引导同位语从句。例如:
I have no idea what has happened to him.
引导词that引导定语从句时,在从句中一般作主语或宾语,(指物时还可用which代替),如果在从句中作宾语常可以省略。that在同位语从句中虽不充当任何句子成份,但不能省略,也不能用which来代替。例如:
<1>The order that we should throw away our luggage was received yesterday.
<2>The order (that)we received yesterday was that we should throw away our luggage.
通过比较可知:第<1>句中的划线部分是对名词order的具体解释,that只起到连接作用,但不能省;第<2>句中的划线部分是名词order的修饰语,that代指the order,在从句中充当宾语,因而在句中可以省略。
状语从句
Adverbial Clauses
状语从句是副词性从句,它在句子中担任状语,修饰主句的动词、形容词或副词。根据修饰的方面,状语从句可以分为以下九种。
1、时间状语从句
2、地点状语从句
3、原因状语从句
4、目的状语从句
5、结果状语从句
6、条件状语从句
7、方式状语从句
8、 让步状语从句
9、 比较状语从句
1、时间状语从句

although Although (Though) he was over sixty, (yet) he began to learn French.
虽然他六十多岁了,但仍开始学习法语 。
We were not tired though (although) we had worked all day.
虽然我们干了一天活,但并不累。 在句子中一般用了“虽然”就不能再用“但是”(but)但可以与yet或still连用。though / although意义相同,用法基本一样,前者通俗,口语化,后者正式多放主句的前面。

句 even if
even though I’ll go even if (though) it rains tomorrow.
即使明天下雨,我也要去。 even if 和even though的意思为“即使”“纵使”有退一步设想的意味,多用于书面语中。

though或although引导的从句,语气强,更有表现力,从句常放在句首,语序部分倒装。



no matter (who, what when, where which, how…) Do it no matter what others say.
不管别人怎么说,尽管干。
No matter how busy he was, he studied English every day.
不管他多忙,他都每天坚持学习英语。
No matter who takes up the matter for me ,I shall be very grateful.
不管谁为我处理这件事,我都将非常感激。 no matter……与 who-ever引导的让步状语从句意义基本一 样,no matter……引导的从句可是以位于主句前或主句后。

句 wh-ever (whatever whoever whenever whichever however) Whatever happens / may happen , we shall not lose heart.
无论发生什么,我们都不要失去信心。
Whoever comes, he will be welcome.
无论谁来,都会受到欢迎。 wh-ever从句中的动词有时可以和may连用。判断wh-ever引导的是状语从句还是名词性从句的一点是,名词性从句,主句中一定有一个成分要在从句担任,一般从句与主句之间没有逗号。
不可将no matter与wh—ever连用



语 as…as
not so/as
…as
the same
…as
such…as Mary is as old as my sister.
玛利和我姐姐一样大。

The warmer, the better.
越暖和越好。 the more…the more 意思为越…越…,通常的语序为从句在前主句在后,这两个the都是表示程度的副词,用在比较级的形容词或副词前面。
句子意思明显,句子的主语和动词都可省略。








句 that We are sure (that )the four modernization will be realized in China .
我们相信四化一定会在中国实现。
I’m sorry (that) I didn’t have time to write you sooner.
很抱歉,我没有抽出时间早点给你写信。
I am afraid that I can’t go with you.
恐怕我不能同你一起去了。 that 引导的从句,往往跟在一个做表语的形容词后面,从句概念上看是宾语,所以有的语法家把它看做是宾语从句,但结构上看,也可以把它看作是一个特殊的状语从句,用来修饰表语的形容词。这种从句的连词常常被省略。
