英语三大从句
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从
句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
定语从句
一、关系代词引导的定语从句
关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示：
（一）关系代词who, whom和whose的用法
who代替人，是主格，在定语从句中作主语。
An architect is a person who designs buildings. 建筑师是设计房屋的人。
whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。
Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先
生你认识吗？
whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。
The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在
国外留学。
Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，
你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。）
（二）关系代词which的用法
which代替物，在定语从句作主语或宾语，作宾语时还可省略。
I do not like stories which have unhappy endings.
我不喜欢有不幸结局的小说。（which可以换成that）
（三）关系代词that的用法
that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。：Is she the girl that sells newspapers?
她是卖报纸的那个女孩吗？（that可以换成who）
Where is the ice-cream that was in the fridge?
放在冰箱的冰激凌哪儿去了？（that可以换成which）
Is this the book that you want to buy?
这是你要买的那本书吗？（that可以换成which，在定语从句作宾语，还可以省略）
二、关系副词引导的定语从句
常用的关系副词只有三个：when, where, why，在定语从句中充当时间、地点和原因状语。
（一）关系副词when的用法
关系副词when代替的先行词表示的是时间，when在定语从句作时间状语。
In Beijing July and August are the months when it rains very often.
北京的七月和八月是常下雨的月份。（when先行词是months）
（二）关系副词where的用法
关系副词where代替的先行词表示的是地点，where在定语从句作地点状语。
During the Spring Festival I went back to the town where I was brought up.
春节期间，我回到了生我养我的家乡。（where的先行词是town）
（三）关系副词why的用法
关系副词why代替的先行词表示的是原因，why在定语从句作原因状语。
The reason why I am phoning you is to ask you whether you have got my email.
我打电话给你的原因是想问问你是否收到了我的电子邮件。（why先行词是reason，当代英语里why可以用that 替代，这时关系代词that就变成了表示原因的关系副词，还可以将why省略）
三、特殊关系代词as引导的定语从句
（一）在固定搭配as…as, so…as, such…as, the same…as中，as引导定语从句
You may take as many books as you want.
你想要拿多少书就拿多少。（第一个as是副词，修饰many的；第二个as才是关系代词，代替先行词books，在定语从句中作宾语）
（二）独立于主句之外，as引导定语从句
As we know/ As is known to us, the earth turns around the sun. 正如我们所知，地球围绕太阳旋转。
（As we know和As is known to us均为定语从句，as分别作宾语和主语，替代后面的主句。）
Taiwan is, as you know, an inseparable part of China.
你知道，台湾是中国不可分割的一部分。（关系代词as指代整个主句，在定语从句中作宾语。）
四、关系代词who, which与that的区别
（一）关系代词who与that的区别
1. 当关系代词用作主语时，多用主格who。He who loses hope loses all.
失去希望的人就失去一切。（先行词为代词he, they, any, all, one等时，多用who）
I met Alice, who told me that she was learning Chinese.
我遇见艾丽斯，她告诉我她在学汉语。（在非限制性定语从句中，用who）
2. 当关系代词用作介词后的宾语时，用宾格whom，不用that。
The man to whom our headmaster talked just now is our English teacher.
我们校长刚才与他谈话的那个人是我们的英语老师。（介词与关系代词紧密相连时，只能用宾格whom，不可用主格who）
注意：介词与关系代词不是紧密相连时，或者说介词放在句子后面时，这时可以用主格who，也可用that，还可以省略关系代词。因此，上面的这句话还可以有如下四种说法：
(1) The man whom our headmaster talked to just now is our English teacher.
(2) The man who our headmaster talked to just now is our English teacher.
(3) The man that our headmaster talked to just now is our English teacher.
(4) The man our headmaster talked to just now is our English teacher.
3. 当关系代词泛指人时，多用that。
He is a man that is never afraid of failure.
他是个从不怕失败的人。（that用来泛指人）
4. 当关系代词出现在who开头的疑问句时，应用that。例如：
Who is the girl that is talking to Tom in English?
用英语同汤姆交谈的那个女孩是谁？（避免重复使用who，以免造成误解或语义含混不清）
（二）关系代词which与that的区别
1. 当先行词为all, much, little以及不定代词anything, something, everything等时，关系代词多用that。
All that glitters is not gold. 闪闪发光物，未必尽黄金。
She told me everything that she knew. 她把她所知道的一切都告诉了我。
2. 当先行词的前面有形容词最高级、序数词或限定词the only, the very, all, every, any, no等时，关系代词一般都
用that。
This is the best novel that I have ever read. 这是我读过的最好的一部小说。
He is the only person that has been invited to the ball. 他是惟一应邀参加舞会的人。
3. 当关系代词出现在which开头的疑问句时，应用that。
Which was the hotel that was recommended to the foreign guest? 哪一个是推荐给外宾的宾馆？（这里使用that很明显是为了避免重复which）
4. 在非限制性定语从句中，关系代词一般只用which。
Beijing, which is the capital of the People’s Republic of China, will host the 2008 Olympic Games. 北京是中华人民共
和国的首都，将主办2008年奥运会。
5. 介词后的关系代词用which，而不用that。
She has collected 600 stamps, 60% of which are German stamps. 她收集了600张邮票，其中60％是德国邮票。
五、定语从句的位置
如前所述，定语从句一般总是直接置于所修饰的名词或代词之后。有时候，定语从句与先行词之间插入了其他的
短语，这样它们被分隔了，这种情况下的定语从句被称作隔离定语从句。
There was a girl upstairs who was shouting and crying, obviously mad.
楼上有一个女孩，大喊大叫。很明显，她疯了。（定语从句who was shouting and crying修饰the girl，被upstairs 所隔开）
A new master will come tomorrow who will teach you German.
明天要来一位新老师教你们德语了。（定语从句置于句末以示强调）
名词性从句
宾语从句
一、引导词
（1）由that 引导的陈述句性的宾语从句，在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that只起连接作用，在从句中不做句子的成分，也无词汇意义，在口语中常被省略。如：I told him that he was wrong.
在think, believe, suppose, expect等动词引起的宾语从句中，有时谓语尽管是否定意义，却不用否定形式，而将
think 等动词变为否定形式。（见语法：否定转移）
如：I don’t think you are right. (我认为你做的不对)
在许多带有复合宾语的句子中，that引导的宾语从句经常移到句子的后面，而用it做形式宾语。
We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的)
（2）由连词if、whether 引导的表示“是否…”的宾语从句。
Whether, if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。
I don’t know if/whether he will come tomorrow.
在介词后面的宾语从句中不用if引导
Everything depends on whether we have enough money.
宾语从句中有or not时不用if引导.
I don’t know whether the movie star will come or not.
和不定式连用作宾语时不用if引导
Whether to go there or not hasn’t been decided.
（3）由wh-引导的宾语从句。连接代词who, whom, whose, what, which和连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的成分。
Do you know which film they are talking about? (which做定语)
I don’t know where he lives. (where 做地点状语)
二、宾语从句的语序，
宾语从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分I believe that they will come soon.
特例：有下列常见的问句，作为从句出现，是“不改变语句顺序”的。
1. What's the matter?
2. What's wrong?
3. What's up？
4. What's the problem?
5. What's your trouble?
三、宾语从句的时态。
宾语从句的时态受主句的限制，即：主句是一般现在时态，从句根据实际情况而定；主句是
一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主句之前，则从句要用过去完成时态。
1) She says that she is a student.→She said that she was a student.
2)She says that she will fly to Japan in a week. →She said that she would fly to Japan in a week.
3)She says that she has finished her homework already. →She said that she had finished her homework already.
（1）如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。
The teacher said that the earth goes round the sun.
（2）Could you tell me…是用来征询对方的意见，语气委婉，并不表示过去。
Could you tell me when we will visit the History Museum?
注意事项：
（3）由陈述句变成宾语从句时，要注意人称的变化。
She said: “I have been to England before.”→She said that she had been to England before.
She asked me: “Do you like maths?”→She asked me if I liked maths.
（4）宾语从句与简单句的交换。
由连接代词和连接副词引导的宾语从句，如果宾语从句的主语和主句的主语是同一个人时，可以用“疑问词+不定式”做宾语的简单句结构。
I don’t know what I should do next. →I don’t know what to do next.

同位语从句
（一）一般来说，在主从复合句中，用作同位语的从句叫同位语从句。它通常跟在某些名词之后，用以说明或解
释该名词表示的具体内容。可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word（消息），problem，question, doubt, thought等。
eg: They were delighted at the news that their team had won.
当听到他们队获胜的消息时，他们欣喜若狂。
有时同位语从句可以不紧跟在被说明的名词后面，而被别的词隔开。如：
The thought came to him that Tom might have returned the book.
他突然想起汤姆可能已经还了书了。
（二）引导词
1. The news that Mr. Li will be our new English teacher is true.
2. He hasn’t made the decision whether he will go there.
3. The question who should do the work is being discussed at the meeting.
4. I have no idea what the boy is doing in the next room now.
5. We haven’t yet settled the question where we are going to spend our summer vacation this year.
6. I have no idea how I can get to the railway station.
7. I have no idea when he will be back．
小结：①that引导同位语从句时无词义，也不充当任何成分，但通常不可以省略，如句1；
②whether引导同位语从句时意为“是否”，通常不能用if来代替, 如句2;
③连接代词who, what等可以引导同位语从句，如句3，4；
④连接副词where, how, when等可以引导同位语从句，如句5，6，7。
(三) that 引导的同位语从句和定语从句
①意义不同：同位语从句用来进一步说明前面名词的内容；而定语从句用来修饰、限定前面的先行词。试比较：
1. The news that our team has won the final match is encouraging.
2. The news that you told us is really encouraging.
②that的功能不同：that引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句时，不仅起连接
作用，而且还指代先行词并在从句中充当主语、宾语等成分。试比较：
1. Dad made a promise that he would buy me a CD player if I passed the English test.
2. Dad made a promise that excited all his children.
③可否省略：that在引导同位语从句时，通常不可省略。在引导定语从句时，若在从句中作宾语，通常可以省
略，若作主语则不可以省略。

表语从句
表语从句只能置于主句之后，而主句的动词只能是连系动词。名词性从句在be等系动词后作表语时被称为表语从句
The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)
The scissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语)
What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作
直接宾语，that作为表语从句的引导词在该表语从句中不充当句子成分，不能省略) That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)
That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语) “That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结
下面是两个与“That is why...”形式相似的结构，它们与“That is why...”结构之间的关系要能够辨析清楚：
(1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why引导的是—个定语从句，将其中的the reason去掉则与“That is why...”结构一样That is (the reason) why
I cannot agree.
(2)“That is because...”句型中从属连词because引导的名词性从句在此作表语，这也是个常用句型，意为“这就是为什么……/因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果
He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去
看电影，那是因为他得帮助他的妹妹做作业。(第一句话说明结果，第二句话说明原因)
He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影，因此他昨天晚上没有
去看。(第一句话说明原因，第二句话说明结果)

表语从句与宾语从句的关系
宾语从句和表语从句都属于名词性从句。其作用跟名词在句中的作用相同。故充当宾语的句子叫宾语从句，充当
表语的句子叫表语从句。
宾语从句
(1)对于宾语从句要掌握以下三点
①语序: 从句的语序必须是陈述句语序, 即“主语+ 谓语”这种形式。
②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时)。
③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去
当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否)
当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词。
表语从句
在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面。表语从句的引导词和主语从句的引导词相同。
也是名词性从句的一种。
What the police want to know is when you entered the room.警察想知道的是你什么时候进的房间。
The trouble is that we are short of funds困难是我们缺乏资金。
This is what we should do这是我们应当做的。
That is why I want you to work there那就是我要你在那儿工作的原因。
His first question was whether Mr. Smith had arrived yet他的第一个问题是史密斯先生到了没有。从句中的疑问句用正常语序，即陈述语序。
as if, as though, because也可用来引导表语从句。
She seems as if she had done a great thing她看起来好像做了一件大事。
It is because you eat too much那是因为你吃得太多了。
状语从句
（一）状语从句的种类
1.时间状语从句
2.地点状语从句；
3.原因状语从句；
4.条件状语从句；
5.目的状语从句；
6.让步状语从句；7比较状语从句；8.程度状语从句；9.方式状语从句；10.结果状语从句。
（二）状语从句的时态
一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表
示“将来完成时”。
（1）时间状语从句
1.由when, while, as引导的时间状语从句。
when, while和as的区别：when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。
While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while 有时还可以表示对比。
While my wife was reading the newspaper, I was watching TV.
As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。
As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不
强调开始下雪的特定时间）
2.由before和after引导的时间状语从句。
before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。时态：当主句用将来时，从句总是用现在时；如果before引导的从句谓语用
的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。
After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。
3.由till或until引导的时间状语从句。
till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是
瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意
思不同。
4.由since引导的时间状语从句。
since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动词用一般过去
时，而主句的谓语动词用现在完成时。但在It is ＋时间＋
since从句的句型中，主句多用一般现在时。
5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些
连词都表示“一……就”。
hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意。主句用过去完成时，从句用一般
过去时。当hardly, scarcely, rarely和no sooner位于句首时，主句应用倒装语序。
6.由by the time引导的时间状语从句。时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的
谓语动词用过去完成时；如果从句的谓语动词用一般现在时，主句的谓语动词用将来完成时。
7.由each time, every time和whenever引导的时间状语从句。
8.由as long as和so long as引导的时间状语从句。这两个连词表示“只要；和…一样长”。
（2）地点状语从句
地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，：
句型1：Where＋地点从句，（there）＋主句。
此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，
一般都不用there。
句型2：Anywhere/ wherever＋地点从句，＋主句。
状语从句是句子的状语由一个从句充当，来修饰主句中的动词，形容词或副词等。状语从句都由从属连词引导，
与主句连接，放在句末时，一般不在前面加逗号。
（3）原因状语从句：because, since, as和for都表示原因。because语势最强，
回答why提出的问题，用来说明人所不知的原因。当能够很明显的看出原因或人们已知原因，就用as或since。由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多
种情况加以推断，就只能用for。
（4）目的状语从句：表示目的状语的从句可以由in order that, so that,等词引导。
（5）结果状语从句：结果状语从句常由so...that 或such...that引导，首先要了解
so和such后面分别跟什么词。such是形容词，修饰名词或名词词组，so是副词,只能修饰形容词或副词。so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。
The box is so heavy that I can't carry it.
（6）让步状语从句：是由though, although 引导的状语从句。
从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms.

复合句 【语法要点】 复合句是由一个主句加一个或几个从句所构成的句子。从句只用作句子的一个成分，不能独立。根据从句在句子中的作用，可分为名词性从句、定语从句和状语从句三类。 （一）名词性从句 名词性从句包括主语从句、表语从句、宾语从句、同位语从句。其关联词有连接词that、if、whether；疑问代词who、what、which和疑问副词when、where、how、why等。 1.名词性从句句法结构： 从 属 连 词that whether 主 语 从 句 That he will come is certain.（that不可省） Whether she is coming or not doesn’t matter too much. （不能用if） 宾 语 从 句 I think（that）he will be all right in a few days. I went in and asked if（=whether）they had a cheap suit. I wonder whether（不能用if）it is true or not. 表 语 从 句 The fact is（that）I have never been there. The question is whether（不能用if）it is worth doing. 同 位 语 从 句 The fact that she had not said anything surprised all of us. They asked me the question whether the work was worth doing. 连接代词 that who whom whose which 主 语 从 句 Who will help him is not known. What he said is very important. Which side will win is not clear. 宾 语 从 句 （1）作及物动词的宾语。例如： I really don’t know what he is doing. Do you know who/whom they are waiting for? He asked whose dictionary it was. He can’t tell which method they will use for the experiment. （2）作介词的宾语。例如： Pay attention to what the teacher said. I wondered to whom he had given the letter. 表 语 从 句 That is what he is worried about. The question is who will come here. The question is which team will win the match.
【宾语从句】 在英语中，有简单句(只含一个谓语动词)、并列句(用连词连接，含不止一个谓语动词)和复合句(含从句)。本节课我们复习复合句里面的宾语从句 ．．．．。 如：She knows that he will come back soon. I’m afraid that I can’t go to your party. 1.宾语从句的【引导词】 宾语从句的引导词分三种。 ●(1) 如果从句是陈述句，引导词用that.（that在口语中常省略） 主句：He says... 从句：He is tired of playing computer games. → He says that he is tired of playing computer games. ●(2) 如果从句是一般疑问句，引导词用if/whether，表示“是否”。 主句：I don’t know… 从句：Does Tom likes fish? → I don’t know if / whether Tom likes fish. 【注意】① whether引导的从句常与or not连用，而if不能； ②宾语从句可简化为whether to do的搭配，而没有if to do这种搭配. 如：Could you tell me whether I should finish my homework today or not? Could you tell me whether to finish my homework today? 【拓展】if有两个意思： 1. 表示“是否”，引导的是宾语从句。动词的时态视情况而定。 2. 表示“如果”，引导的是条件状语从句，时态用一般现在时表示将来（遵循“主将从现”规则）。 经典例题：--Do you know if Tom ____________(go) hiking with us ? --I’m not sure. But i f he ____________(go), I will take many photos with him . ●(3) 如果从句是特殊疑问句，直接用该疑问词来引导。 主句：Do you know… 从句：what does he want to buy? → Do you know what he wants to buy? 你知道他想要买什么吗？ 2. 宾语从句的【时态】 ■(1) 当主句是一般现在时，从句根据情况使用任何时态 如：She wants to know if I have finished my homework. 她想知道我是否已经完成了我的作业。 Do you know when he will be back? 你知道他将会什么时候回来？ ■(2) 当主句是一般过去时，从句应使用过去的某时态 如：He said that she was singing. 他说她正在唱歌。 She wanted to know if I had finished my homework. 她想知道我是否已经完成了作业。 Did you know when he would come back? 你知道他将会什么时候回来？ 【注意】格言和客观真理总是用一般现在时。 如：She told me yesterday (that) the earth travels around the sun.

定语从句 一、基本概念： 定语： 定语从句： Do you know the man who spoke at the meeting just now That is the house where he lived ten years ago. 引导词：关系词 关系代词有：that, who, whom, whose, which; 在从句中充当： 关系副词有：when, where, why. 在从句充当： 先行词： 定语从句中引关系词的作用： 二、关系词的用法： （一）关系代词的用法： 1． He is the man lives next door. The train has just left is for Shenzhen. 2． The man ________ we have just seen is a famous writer. Where is the book ___________I bought last week （二）关系副词的用法： 1． I still remember the time ________I first became a college student. Do you know the date __________Lincoln was born
(三) 使用关系副词应注意下列几点： 1．这三个关系副词在意义上都相当于一定的介词+which结构： when = on (in, at, during…) + which; where = in (at, on…) + which; why = for which. 如： I was in Beijing on the day when (=on which) he arrived. The office where (=in which) he works is on the third floor. This is the chief reason why (=for which) we did it. 2．当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较： I’ll never forget the day _________ my hometown was liberated. I’ll never forget the days____________we spent together last summer. His father works in a factory____________radio parts are made. His father works in a factory______________makes radio parts. 三．限制性定语从句与非限制性定语从句 1．限制性定语从句 This is the telegram which he refers to. Is there anything (that) I can do for you 2．非限制性定语从句 This note was left by Tom, who was here a moment ago. As a boy, he was always making things, most of which were electric.
一. 宾语从句object clause： 一. 定义definition： 在句子中起宾语作用的从句叫做宾语从句。 二. 连接词connections： that: I think that you can pass the exam. Whether/if: I don’t know what the word means. “Wh”: I don’t know what the word means. I don’t know where he found the book. 只用whether的情况： 1. 与or not连用： I don’t know whether it’s raining or not. 2. 与动词不定式连用： He doesn’t know whether to accept the invitation. 3. 连接词前有介词时： It depends on whether he is coming. 三. 时态tenses: 1. 主句是一般现在时态，从句根据实际情况而定(各种时态均可) She wants to know what he has done for the exam. 2.主句是一般过去时态，从句用相应的过去的时态。 1）She said that she was a student. 2）She said that she would fly to Japan in a week. 3）She said that she had finished her homework already. 3. 如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。 The teacher said that the earth goes round the sun. 二. 定语从句Attributive clause： 1.定义：在复合句中修饰名词、代词的从句叫定语从句 2.先行词指人who /that 先行词指物which/ that 3. 定语从句一般紧跟被修饰的名词或代词（即先行词）后 4.关系代词代替先行词在句子中担当成分，所以从句中不可再出现其他代替先行词的代词 5.翻译方法“…. 的” Eg. 1. Yesterday we bought a book which is really hard to understand. 2. The students who are from Maple Leaf School like learning English. Whom: 先行词指人，则代替先行词在定语从句中充当宾语（包括介词的宾语）, 与who的区别是如果前面带介词则必须用whom 1.This is the teacher whom\who we like best. 2. I don’t like the boy to whom you are talking. Whose : 指人或物，作定语，表示“…的” eg: Harry is the boy whose mother is our math teacher.
第五讲并列句和三大从句 第一组定语从句 1.(2020辽宁大连双基测试，)The 55-km Hong Kong Zhuhai-Macao Bridge, ____________________was opened on Oct. 24, 2018connects Guangdong Province with China's two special administrative regions, Hong Kong and Macao. 2.(2020黑龙江哈尔滨三中二调，)In 1984,Dr.Mary Groda-Lewis, ____________________was thirty-five years old then, graduated with honors and realized her dream 3.(2020陕西咸阳)He said,"...I added a small moustache____________________would add age without hiding my expression." 4.(2020新疆乌鲁木齐二诊)The act,____________________forbids trading, was passed in 1448 and is still in force. 5.(2020陕西汉中一模，41)Our office wasn't far from Chinatown,____________________ I found some very good Chinese restaurants 6.(2020黑龙江大庆一中)As more and more people own private cars, parking has become a big headache for many car owners, especially for those____________________ live in downtown areas without enough parking spaces. 7.(2019黑龙江哈尔滨六中二模，61)Now millions of fans are eagerly awaiting its eighth and final season,____________________starts on April 14. 8.(2018陕西宝鸡质检，65)Then,a fire,____________________broke out in1969 on Cleveland's Cuyahoga River, shed light on the problem of chemical pollution in water. 【答案】 1.which 句意：长55公里的港珠澳大桥于2018年10月24日开通，它将广东省与中国的两个特别行政区——香港和澳门——连接起来。设空处引导定语从句，指代先行词The 55-km Hong Kong-Zhuhai-Macao Bridge,关系代词在从句中作主语，故填which。 2.who 句意：1984年，Mary Groda-Lewis博士以优异的成绩毕业并实现了自己的梦想，当时她35岁。先行词为Dr.Mary Groda-Lewis,设空处引导非限制性定语从句，在从句中作主语，故填关系代词who。 3.which 句意：他说：“……我增加了一小最胡子，这会在不掩盖表情的情况下让我看起来年龄大些。”分析句子结构可知，设空处引导非限制性定语从句，先行词为a small moustache,故用关系代词which。 4.which 句意：这项禁止贸易的法令于1448年通过，至今仍然有设空处指代先行词Theact,故由which引导
高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从
