初中从句

第一篇：初中从句

1）表语从句

1.定义：用作表语的从句叫做表语从句。2.构成：关联词+简单句

He looked just as he had looked ten years before.他看起来还与十年前一样。

The question is whether they will be able to help us.问题是他们是否能帮我们。

注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago，but it’s as if it was only yesterday.这都是20多年前的事了，但宛如昨天一样。

能跟表语从句的谓语动词一般为系动词be，seem，look等。如：It looked as if it was going to rain.看起来天要下雨了。

（3）连接代词who，whom，whose，what，which，whoever，whatever，whichever连接副词 where，when，how，why.如：The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。

The question is how he did it.问题是他是如何做此事的。

1.连词because可引导表语从句。

如：I think it is because you are doing too much.我想这是因为你做得太多。2.在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。

解释：

1.主语从句能用it作形式上的主语。常以it作形式主语的句型有：

A.It+be+形容词（obvious，true，natural，surprising，good，wonderful，funny，possible，likely，certain，probable，etc.）+that从句。如：

It is certain that she will do well in her exam.毫无疑问她考试成绩会很好。

E.It+doesn’t matter（makes no difference，etc.）+连接代词或连接副词引起的主语从句。如：

It doesn’t matter whether she will come or not.她是否来这无关紧要。

It makes no difference where we shall have the meeting.我们在哪里开会毫无区别。

F.当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：

Is it true that the scientist will give us a lecture next week？ 下周那位科学家将给我们作报告是真的吗？

Does it matter much that they will not come tomorrow？ 他们明天不来很要紧吗？

G.当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：

How strange it is that the children are so quiet！孩子们这么安静真奇怪！

2.注意连接代词whoever，whatever，whichever等引导主语从句的含义。

Whoever comes will be welcome.（whoever=the person who）来的人将受到欢迎。

Whatever he did was right.（whatever=the thing that）他所做的事情是正确的。

Whichever of you comes in will receive a prize.（whichever=anyone of you who）你们当中不论哪个进来将会得到奖

3）宾语从句

1.定义：用作宾语的从句叫宾语从句。

2.构成：关联词+简单句。

3.引导宾语从句的关联词有三类：

（1）从属连词that.如：

He told us that he felt ill.他对我们说他感到不舒服。

I know he has returned.我知道他已经回来了。

注： that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。

1.Everybody could see what happened and that Tom was frightened.（and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。）

大家都会看出所发生的事情并知道Tom非常害怕。

2.I know nothing about him except that he is from the south.（that引导的宾语从句作介词宾语时，that不能省略。）

对他我一无所知，只知道他是南方人。

3.That he ever said such a thing I simply don’t believe.（that从句位于句首时，that不可省略。）

我简直不相信他曾说过这样的话。

4.We decided，in view of his special circumstances，that we would admit him for a probationary period.（主句谓语动词与that从句之间有插入语，that不可省略。）

鉴于他的特殊情况，我们决定应允他一段试用期。

（2）从属连词if/whether.如：

I doubt whether he will succeed.我怀疑他是否会成功。

I don’t know if you can help me.我不知道你能否帮助我。

（3）连接代词who，whom，whose，what，which，whoever，whatever，whichever

连接副词 where，when，how，why.如：

Who or what he was，Martin never learned.他是什么人？他是干什么的？马丁根本不知道。

I wonder what he’s writing to me about.我不知道他要给我写信说什么事。

I’ll tell you why I asked you to come.我会告诉你我为什么要你来。

You may do what you will.你可做任何你想做的事。

（1）介词宾语从句

宾语从句也可用作介词的宾语。如：

He was deeply displeased by what had occurred that day.他对那天发生的事感到很不快。

I walked over to where she sat.我走向她坐的地方。

I am curious as to what he will say.我很想知道他要说什么。

Your success will largely depend upon what you do and how you do it.你是否成功将主要取决于你做什么和怎样做。

有时介词可以省略。如：

I don’t care（for）who marries him.我不管谁跟他结婚。

Be careful（as to）how you do that.你要注意做这件事的方式。

解释：

1.如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：

We thought it strange that Xiao Wang did not come yesterday.我们认为小王昨天没来是奇怪的。

He has made it clear that he will not give in.他已表明他不会屈服。

2.作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except，but，in后。其他一些介词的宾语从句如果由连词that引导，则需用it先行一步，作形式宾语。如：

He is a good student except that he is careless.他是一个好学生，只是有点粗心。

You may rely on it that I shall help you.你可以指望我会帮助你的。

介词宾语不可以用which来引导，而要用what来引导。如：

Are you sorry for what you’ve done？

你为你所做的一切感到内疚吗？

3.某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure，glad，certain，pleased，happy，afraid，surprised，satisfied等，连词that可省略。如：I am not sure what I ought to do.我不能确定我该做什么。

I’m afraid you don’t understand what I said.恐怕你没领会我说的意思。

I’m surprised that I didn’t see all that before.我好奇怪，我以前没看到过。

Mother was very pleased her daughter had passed the exams.妈妈为她的女儿通过了考试而感到高兴。4.连词whether（…or not）或if引导的宾语从句

if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不与or not连用。如：

I wonder whether it is true or not.我不知它是真是假。

用if引导宾语从句如果会引起歧义，应避免使用if而用wheter.试比较：

Please let me know if you want to go.Please let me know whether you want to go.if从句可理解为宾语从句，意为“请告诉我你是否想去”；此句又可理解为条件状语从句意为“如果你想去的话，请告诉我一声”。

5.宾语从句的否定转移。在think，believe，suppose，expect等动词后的宾语从句，有时谓语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式。如：

I don’t think you are right.我认为你错了。

I don’t believe they have finished their work yet.我相信他们还未完成他们的工作。

I don’t suppose he cares，does he？ 我想他不在意，是吗？

6.宾语从句的时态变化规律：

（1）当主句是一般现在时态时，从句可根据需要用任何时态。

（2）当主句是一般过去时态时，从句只能使用过去范围内的任何时态。但客观真理除外。如：

The teacher said that the earth goes round the sun.老师说地球绕着太阳运行。

4）同位语从句

1.定义：用作同位语的从句叫做同位语从句。

2.用法：同位语从句的先行词多为fact，news，idea，thought，question，reply，report，remark等，关联词多用从属连词that.如：

They were all very much worried over the fact that you were sick.对你生病这件事，他们都很焦虑。

Where did you get the idea that I could not come？

你在哪儿听说我不能来？

Early in the day came the news that Germany had declared war on Russia.德国已对俄国宣战的消息一大早就传来了。

注：同位语从句偶尔由从属连词whether引导。如：

I have no idea whether he’ll come or not.我不知道他是否来。

连接代词who，which，what和连接副词where，when，why，how亦可引导同位语从句。

The question who should do the work requires consideration.谁该干这项工作，这个问题需要考虑。

We haven’t yet settled the question where we are going to spend our summer vacation.到哪儿去度暑假，这个问题我们还没有决定。

It is a question how he did it.那是一个他如何做了此事的问题。

解释：

1.that引导的同位语从句与定语从句之区别

that引导的同位语从句

that引导的定语从句

句法功能上

that只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。

that替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。

意义上

从句是被修饰名词的内容。

从句起限定作用，是定语

如：The news that Mr.Li will be our new English teacher is true.（同位语从句，that不可省。）

李先生将是我们的新英语老师这个消息是真的。

The news（that）he told me yesterday is true.（定语从句，that在从句中作told的宾语，可省。）

他昨天告诉我的消息是真的。

2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：

This is our only request that this（should）be settled as soon as possible.这就是我们唯一的请求：尽快解决这个问题。

（6）不定式的构成 1.不定式的构成

不定式是由不定式符号to+动词原形构成，在某些情况下to也可省略。

不定式一般有时式和语态的变化，通常有下表中的几种形式（以do为例）：

主动式 to do

被动式 to be done

完成式to have done /to have been done

进行式 to be doing

完成进行式 to have been doing

1）不定式的一般式

不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生，或是在它之后发生。如：

They invited us to go there this summer.他们邀请我们今年夏天去那儿。

He stood aside for me to pass.他站到一边让我通过。

2）不定式的完成式

不定式的完成式所表示的动作在谓语所表示的动作之后发生，它在句中可作表语、状语、宾语，有时也可作主语、定语等。如：

She seemed to have heard about this matter.她似乎已听说过这件事。

I meant to have told you about it，but I happened to have an important thing to do.我本来想告诉你这件事的，但我碰巧有一件重要的事要做。

3）不定式的进行式

不定式的进行式表示正在进行的与谓语动词同时发生的动作。它在句中可以用作除谓语以外的所有成分。如：

It’s nice of you to be helping us these days.你真好，这些天一直帮我们。

He pretended to be listening to the teacher carefully.他假装在认真地听老师讲课。

4）不定式的完成进行式

如果不定式表示的动作是谓语所表示时间之前一直进行的动作，就需要用完成进行式。如：

They are said to have been working in Tibet for 20 years.据说他们已经在西藏工作20年了。

We are happy to have been helping each other these days.我们很高兴这些天能互相帮助。

5）动词不定式的否定形式是由not或never加不定式构成。如：

Try not to be late again next time.尽量下次不要再迟到。

He wished us never to meet her again.他希望我们永远不要再见到她。

6）疑问词+动词不定式：

不定式和疑问词whether，what，which，whom，where，when，how，why等连用可以在句中起名词的作用，通常跟在tell，know，show，decide，learn，wonder，explain，advise，teach，discuss，find out等动词后面作宾语，有时也可以充当主语、表语等。如：

On hearing the news，he didn’t know whether to laugh or to cry.听到这个消息，他不知道该哭还是该笑。

When to hold the meeting has not decided.什么时候开会还没有决定。

介词后一般不直接接不定式，但可以接疑问词+不定式短语作宾语。如：

Mary gave some advice on how to learn English.玛丽提了一些如何学习英语的建议。

I have no idea of how to do it.我不知道该怎么做。

第二篇：初中定语从句

定语从句

一.定语从句的功用和结构

在复合句中，修饰某一名词或代词的从句叫做定语从句。被定从句修饰的词叫做先行词。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如：

This is the present that he gave me for my birthday.Do you know everybody who came to the party? I still remember the night when I first came to the village? This is the place where Chairman Mao once lived.二.各个关系代词和关系副词的具体用法

1.who 指人，在定语从句中作主语。例如：

The person who broke the window must pay for it.The boy who is wearing the black jacket is very clever.2.whom指人，在定语从句中作宾语。例如：

Do you know the young man(whom)we met at the gate？ Mr Lee(whom)you want to see has come.3.whose 指人，在定语从句中作定语。例如：

The girl whose mother is ill is staying at home today.I know the boy whose father is a professor.4.which指物，在定语从中作主语或宾语。例如：

A dictionary is a book which gives the meaning of words.Here is the book(which)the teacher mentioned yesterday.5.that多指物，有时也指人，在定语从句中作主语或宾语。例如： I’ve read the newspaper that(which)carries the important news.Who is the person that is reading the newspaper over there? 6.when 指时间，在定语从句中作状语。例如：

I’ll never forget the time when we worked on the farm.He arrived in Beijing on the day when I left.7.where 指地点，在定语从句中作状语。例如：

This is the house where we lived last year.The factory where his father works is in the east of the city.三.关系代词 whom，which 在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从句之间，有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写，而将介词置于定语从句的后面，如：

That was the room in which we had lived for ten years.= That was the room which we had lived in for ten years.四.具体使用时还要注意下列问题：

1.只能使用that,不用which 的情况：

(1)先行词是all, few, little, nothing, everything, anything 等不定代词时。例如：

All that he said is true.(2)先行词被only, no, any, all,等词修饰时。例如：

He is the only foreigner that has been to that place.(3)先行词是序数词或被序数词修饰的词。例如： He was the second(person)that told me the secret.(4)先行词是形容词最高级或被形容词最高级修饰的词。

This is the best book(that)I have read this year.(5)先行词既包括人又包括物时。例如：

He talked about the people and the things he remembered.2.只能用which，不用that 的情况：(1)在非限制性定语从中。例如：

The meeting was put off, which was exactly what we wanted.(2)定语从句由介词+关系代词引导，先行词是物时。例如：

The thing about which he is talking is of great importance.一.单项填空

第三篇：初中定语从句

定语从句

定语从句是在主从复合句中修饰某个名词或代词句子，它在句中作定语。被修饰的名词或代词叫先行词，连接先行词和定语从句的词叫引导词(也叫关系词)。如 I know the girl who is sitting under the tree.我认识那个正坐在树下的女孩。↓ ↘引导词 ↓

先行词 从句(定语从句)This is the most interesting book that he has ever read.这是他所读过的书中最有趣的一本。↓ ↘引导词 ↓

先行词 从句(定语从句)考点1：先行词是人时引导词的选用

(1).先行词是人，引导词后紧跟动词时用who或that.如：

Here comes the man who(that)wants to see you.想见你的那个人来了。(先行词是the man, 引导词后紧跟动词wants, 故引导词用who / that)(2).先行词是人，引导词后紧跟的不是动词时要用who, whom, that.如： This is the person whom(who, that)you are looking for.这正是你要找的人。

(先行词是the person, 引导词后紧跟的是you, 不是动词, 故引导词可用who / whom / that)考点2：先行词是物时引导词的选用

(1).先行词是物时，一般情况下引导词可以用which或that.如：

Mary like music that(which)is quiet and gentle.玛丽喜欢安静柔和的音乐。(先行词是music, 引导词可用which / that)The film which(that)we saw last night was very interesting.我们昨晚看的电影非常有趣。(先行词是film, 引导词可用which / that)。

Have you written down everything that Mr.Lin has said? 你写下林先生所说的每样东西了吗？ All that can be done has been done.能做的所有事情都己经做了。There is little that I can do for you.我能为你做的事几乎没有了。

②.当先行词由以下词修饰时，引导词只用that.这些词有：only, very, the same, the last, all, any, some, no, little, few等。如：

That is the very dress that I want to buy.那正是我要买的裙子。English is the only subject that I like.英语是我唯一喜欢的科目。Cleaning the room again is the last thing that I can do for you.再次打扫房间是我能为你做的最后一事。

③.当先行词有序数词或形容词最高级修饰时，引导词只用that.This is the fifth school that I have taught so far.这是我目前为止教过的第5所学校。Mr.Li’s class is the most interesting one that I have ever had.李老师的课是我上过的最有趣的课。

④.当先行词有人又有物时，只能用that。如：

Can you remember the writer and his books that we have reported? 拓展知识 考点3：先行词是时间，地点，原因时引导词的选用

(1).先行词是时间, 地点，原因并在从句中作状语时, 引导词分别用when, where, why, 也可以用介词+which结构。如：

I wanted to know the day when he was born.=I wanted to know the day on which he was born.我想知道他出生在哪一天。

He still loved the school where we studied together two years ago.=He still loved the school in which we studied together two years ago.他仍然爱那所我们两年前一起读书的学校。

Do you know the reason why he was late for school? 你知道他迟到的原因吗？(2).先行词是时间, 地点并在从句中作主语或宾语时, 引导词用which或者that。如： I remember the days which(that)we spent on the farm.我记得我们在农场渡过的日子。Lu Ming studies in the school which(that)was built 1 years ago.卢明在一所1年前建好的学校里读书。

考点4：引导词前有介词时，先行词是人,引导词只能用whom, 先行词是事物时，引导词只用which。如：

This is the friend to whom I talk a lot.这是跟我谈话很多的朋友。

Jacky stayed in the room in which Lu Xun once lived.杰克呆在那个鲁迅曾经住过的房间。

考点5：先行词是代词时，先判断其指代人还是指代物，再决定用哪个引导词。如： I don’t like those who talk much but do little.我不喜欢说得多做得少的人。The sleeping tigers are bigger than those which are trained there.这睡着的老虎们比那些被训练的大。宾 语 从 句

宾语从句是在主从复合句中作主句的宾语的句子。如：

Rose said she would visit us sometime next week.露丝说她下星期某时会来看我们。↓ ↓

主句 从句(宾语从句)Could you tell me where he is from? 你能告诉我他来自哪里吗？ ↓ ↓ 主句 从句(宾语从句)考点1：引导词的选用(1).陈述句的引导词用that，常可省略。

I am going to meet my net friends in Guangzhou.He said.→He said that he was going to meet his net friends in Guangzhou.他说他将要在广州见他的网友。

(2).一般疑问句的引导词用if/ whether(是否)。（后有or 时只用whether）Would you like to play basketball with me? He asked me.→He asked me if/whether I would like to play basketball with him.他问我是否会和他去打篮球。Is it a fast train or a slowly one? I wanted to know.→I wanted to know whether it was a fast train or a slowly one.我想知道这是快车还是慢车。

(3).特殊疑问句的引导词用特殊疑问词。How old are you? They want to know.→They want to know how old you are.他们想知道你多大年纪了。What are you going to do this afternoon? He asked me.→He asked me what I was going to do this afternoon.他问我今天下午要做什么。考点2：语序(宾语从句中从句要用陈述句语序，即从句中的第1助动词在主语之后）He asked Jane: “Why don’t you come”? 疑问语序(第1助动词don’t 在主语you之前)He asked Jane why she didn’t come last night.陈述语序(第1助动词didn’t 在主语you之后)Lucy wanted to know if I could make a cake for you.露丝想知道我是否会为你做个蛋糕。特殊：①.What’s wrong with „在宾语从句中不变语序。如： I want to know what’s wrong with you.我想知道你怎么啦。②.引导词在从句中做主语时，语序不变。如： Jack asked me who would give us the lecture this afternoon.杰克问我谁今天下午会给我们做报告。

(who 是引导词，在宾语从句中作动词would give的主语，本身己是陈述语序，不需再变。)考点3：时态（主句从句在时态上要一致）

(1).主句是现在时(一般现在时，一般将来时，现在进行时，现在完成时)，从句该用什么时态就用什么时态。

“John speaks highly of you.‖ Tom tells me.→Tom tells me that John speaks highly of me.汤姆告诉我约翰高度评价我。(主句用tells, 是一般现在时，从句原时态是speaks,在这里还是用speaks)He asked Jane why she didn’t come last night.陈述语序(第1助动词didn’t 在主语you之后)Lucy wanted to know if I could make a cake for you.露丝想知道我是否会为你做个蛋糕。

(2).主句是过去时(一般过去时，过去进行时)，从句只用过去某种相应时态。“When shall we have the meeting?” The boy asked.→The boy asked when they should have the meeting.男孩问他们应该什么时候开会。(主句用asked，是一般过去时，从句用相应的某种过去时，这里shall→should)(3).从句表示客观真理或事实时，主句即使用过去时，从句仍然用一般现在时。“The earth goes around the sun.” The teacher told the students.→The teacher told the students that the earth goes around the sun.老师告诉学生们地球绕着太阳走。

第四篇：初中定语从句

七．定语从句

一.定语从句的概念

在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的词叫关系词，定语从句一般放在先行词的后面。

二.引导定语从句的关系词

引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等，关系副词包括where，when，why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。三.定语从句的分类

根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。四.关系代词的用法

1.that 既可以用于指人，也可以用于指物。在从句中作主语、宾语或表语。作主语时不可省略，作宾语可省略。例如：

Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。（that作主语）The coat（that）I put on the desk is blue.我放在桌子上的那件外套是蓝色的。（that作宾语）

2.which用于指物，在句中作主语、宾语或表语。作主语不可省略，作宾语可省略。例如： The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。（作主语）The film（which）we saw last night was wonderful.我们昨天晚上看的那部电影很好看。（作宾语）

3.who，whom用于指人，who 用作主语，whom用作宾语。在口语中，有时可用who代替whom。who和whom作宾语时也可省略。例如： The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。（作主语）Who is the teacher（whom）Li Ming is talking to？

正在与李明谈话的老师是谁？（作宾语）注意：

（1）当定语从句中含有介词，介词放在句末时，who，whom，that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。例如： This is the house in which we lived last year.这是我们去年居住的房子。

Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

（2）含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如： This is the person whom you are looking for.这就是你要找的那个人。

（3）that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如： The city that she lives in is very far away.她居住的城市非常远。

（4）关系词只能用that的情况：

a.先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which.例如：

He was the first person that passed the exam.他是第一个通过考试的人。

b.被修饰的先行词为all，any，much，many，everything，anything，none，the one等不定代词指物时，只能用that，而不用which.例如： Is there anything that you want to buy in the shop？

你在商店里有什么东西要买吗？

c.先行词被the only，the very，the same，the last，little，few 等词修饰时，只能用that，而不用which.例如： This is the same bike that I lost.这就是我丢的那辆自行车。

d.先行词里同时含有人或物时，只能用that，而不用which.例如： I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片。

e.以who或which引导的特殊疑问句，为避免重复，只能用that.例如： Who is the girl that is crying？

正在哭泣的那个女孩是谁？

f.主句是there be 结构，修饰主语的定语从句用that，而不用which，例如： There is a book on the desk that belongs to Tom.桌子上那本书是汤姆的。

（5）关系词只能用which，而不用that 的情况：

a.先行词为that，those时，用which，而不用that.例如： What’s that which is under the desk？

在桌子底下的那些东西是什么？

b.关系代词前有介词时，which，而不用that.例如： This is the room in which he lives.这是他居住的房间。

c.引导非限制性定语从句，先行词指事物时，用which，而不用that，例如： Tom came back，which made us happy.汤姆回来了，这使我们很高兴。五.关系副词的用法

1.when指时间，其先行词表示时间，when在定语从句中作时间状语。例如：

This was the time when he arrived.这是他到达的时间。

2.where指地点，其先行词表示地点，where在定语从句中作地点状语。例如： This is place where he works.这是他工作的地点。

3.why 指原因，其先行词是原因，why在定语从句中做原因状语。例如： Nobody knows the reason why he is often late for school.没人知道他为什么上学总迟到。

八．时间、条件、原因状语从句

状语从句指在句子中用作状语的从句。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等九种状语从句。

初中阶段，我们学习的状语从句主要有时间状语从句、条件状语从句和原因状语从句，今天我们就来学习以下这三种状语从句。一.时间状语从句

主要连词：when、while、as、as soon as（一......就......）、before、after、since等。

【注意1】时间状语从句要符合“主将从现”的原则：即主句用一般将来时，从句用一般现在时。例如：

I will call you as soon as I arrive in Beijing.我一到北京就给你打电话。

I will give you a call when I arrive at London.我到伦敦后会给你打电话。

【注意2】since 的用法： since引导的时间状语从句必须是一般过去时，其主句必须时现在完成时。例如：

Since I came to Beijing, I have lived here.自从我来到北京，我一直住在这里。

【注意3】while 引导的时间状语从句中，谓语动词必须时持续的;when 引导的时间状语从句中，谓语动词可以持续也可以不持续。例如：

While I was away last summer, my dog was taken good care of.我去年夏天离开的那段日子里，我的狗被照顾的很好。

When I lived in that small village，I often went to play in the field.当我住在那个小山村的时候，我经常去地里玩耍。

When the film ended，all the people began to go out of the cinema.电影结束后，所有的人都开始走出电影院。二.条件状语从句

主要连词：if, unless（除非=if...not...）, as long as（只要）等。【注意】条件状语从句要符合“主将从现”的原则：即主句用一般将来时，从句用一般现在时。例如：

If it is fine tomorrow，we will have a picnic outdoors.如果明天天气好，我们会在户外野餐。

Unless you work hard, you won't succeed.（=If you don't work hard, you won't succeed.）除非你努力工作，否则你不会取得成功。As long as you go, I will go.只要你去，我就会去。三.原因状语从句

主要连词：because, as（由于）, since（因为，既然）等。

【注意】because 引导的原因是未知的原因，as和since引导的原因是已知的原因。例如： I didn't go to school because I was ill.因为我病了，所以没有去上学。

As it is raining heavily, we won't go to the park.由于雨下得很大，我们就不去公园了。

Since everyone is here, let's begin our meeting.既然大家都到了，让我们开始我们的会议吧。

参考答案及解析

1.A.which用作关系代词，在定语从句中作主语。2．C.“和谁讲话”要说speak to sb.本题全句应为Do you know the man whom I spoke to.。whom是关系代词，作介词to的宾语，可以省略。3.D.where是关系副词，表示地点，在定语从句中作地点状语。4.C.when是关系副词，表示时间，在定语从句中作时间状语。

5．A.which是关系代词，在从句中作forget的宾语。其他几个答案都不能作宾语。

6．C.解析同第5题。7.A.解析见第3题。

8.A.本句话的先行词应该是films,因此，关系代词that是负数概念，其谓语动词应用复述的被动语态have been shown。如果句中的one前面使用了定冠词the，则the one应该视为先行词。

9.A.“谈到某事物”应说talk about sth.。about是介词，其后要用which作宾语，不能用that。

10.A.with which是”介词+关系代词“结构,常用来引导定语从句.with有”用“的意思,介词之后只能用which,不能用that.with which在定语从句中作状语,即he is writing with a pen.11.C.in front of which 即in front of a farmhouse.In front of which在从句中作状语.12.D.with whom引导定语从句.with whom放在从句中即为:my father works with the engineer.13.D.whose引导定语从句,在从句中作主语family的定语.14.A.that引导定语从句,因为先行词是all,所以只能选用that引导.15.D.the same……..as是固定用法, as引导定语从句时,可以作主语,宾语或表语.在本句话中,as作从句的主语.16.D.such……… as是固定用法,as引导定语从句时,可以作主语,宾语或表语.在本题中,as作表语.17.B.as作关系代词可以单独用来引导非限制性定语从句。这时as所指代的不是主句中某个名词，而往往指代整个主句的含义。as在从句中可以作主语、宾语。从句可放在主句后，也可置于主句前。在本句中,as作宾语.18.B.Li Ming enjoyed it very much是主句,with whom I went to the concert是定语从句.with whom放在从句中为:I went to the concert with Li Ming.19.C.as引导定语从句时通常构成such…as或the same…as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。as在从句中可以作主语、表语或宾语。Such修饰单数名词时,要用such a……..,本题中such books, such直接修饰复数名词.20.B.things和persons是先行词.当定语从句要修饰的先行词是既表示人,又表示物的名词时,其关系代词要用that.21.D.who引导非限制性定语从句,who作从句的主语.22.C.two thirds of whom 即:two thirds of the 2,000 workers.23.D.先行词person后有两个定语从句,第一个从句省略了关系代词whom.因为, whom作从句中met的宾语,可以省略.第二个从句who could do it.who在从句中作主语,不可省略.24.A.whose title引导非限制性定语从句,whose title也可以说成the title of which 25.A.for which 引导定语从句,使用介词for,是来自于从句中的固定短语 be famous for ”以……..而闻名".26.C.当先行词被such修饰时,引导定语从句的关系代词要用as.As在本从句中作主语.27.A.两个先行词the day都是表示时间的名词,但第一个空白处要填的关系词在从句中作状语,因此要用关系副词when.第二个空白处要填的关系词在从句中作动词spent的宾语,因此要用关系代词which或that来引导定语从句.28.D.在way、distance、direction等词后的定语从句中，常用that来代替“in(或其他介词)+which”、when或where，而that常可省略。29.D.for which在定语从句中作原因状语,可用why 来替代.30.B.which I have looked after 构成一个非限制性定语从句.31.A.The reason why… was that….已成为一种固定句型，这一句中的why和that不能随意换位，也不能将that改成because，尽管that这个词在译文中可能有 “因为”的含义。

32.B.非限制性定语从句常用which引导,which表示前句话的整个含义.33.A.解释见28题.34.D.主句中的two表明不能选A.从句中的are表明不能选B.both of which用来引导非限制性定语从句.35.C.as引导定语从句时通常构成such…as或the same…as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。as在从句中可以作主语、表语或宾语。本题中as作从句的主语.36.B.非限制性定语从句常用which引导,which表示前句话的整个含义.37.D.38.D.解析见35题.39.A.he makes是定语从句, 从句前省略了关系代词that.40.B.which is a bad habit 非限制性定语从句.41.A.what happened是宾语从句.all 之后that he knew是定语从句.先行词是all,所以关系代词只能用that.42.D.years是表示时间的名词,用when引导定语从句,是因为when在从句中作时间状语.第二个空选用which,引导一个非限制性定语从句.43.C.本句话的定语从句是who own cars.其先行词是people,因此,定语从句的谓语动词要用复数的own。本句话主句的主语是The number of指“…..的数目”，是单数概念。因此，主句的谓语动词要用is。

44.D.that followed是定语从句，关系代词that在从句中作主语。45.A.先行词gas被only修饰，关系代词要用that，而不用which。46.B.through which引导定语从句，through which即through the hole,在定语从句中作状语。What引导的是see的宾语从句，并作从句的主语。

47.B.为便于理解，改写本句话：This is the school that some Germanfriends visited last week.不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited的宾语，所以被省略了。其它选项结构不对。48.A.解释见35题。

49.C.因为是two ballpens, 并且定语从句的谓语writes是单数概念。因此，C是正确选项。

50.B.本句话中，主句的主语是all,为抽象概念。因此，其谓语应用单数的has been。关系代词that引导定语从句，并在从句中作主语。13 | 评论
