什么是英语从句？详细说明

Answer 1

关系副词引导的定语从句 判断关系代词与关系副词 限制性和 非限制性定语从句等内容，有例题讲解 定语从句在句中做定语，修饰一个名词或代词，被修饰的名 词词组或代词即先行词。定语从句通常 出现在先行词之后，由关系词(关系代词或关系副词)引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 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.

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。

宾语) 18.2 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。例 如： There are occasions when (on which) one must yield.

何人都有不得不屈服的时候。 Beijing is the place where(in which) I was born.

的出生地。 Is this the reason why (for which) he refused our offer?

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+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.

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。

18.3 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

额(⊙o⊙)…，先行词的问题不理解么？

先行词主要看它在定语句子中坐的成分

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
3.引导表语从句的关联词的种类：
（1）从属连词that.如：
The trouble is that I have lost his address.麻烦是我把他的地址丢了。
（2）从属连词whether，as，as if.如：
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。
That was what she did this morning on reaching the attic.那就是她今晨上了阁楼干的。
解释：
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。如：
My suggestion is that we （should）start early tomorrow.我的建议是我们明天一早就出发。
2）主语从句
1.定义：用作主语的从句叫做主语从句。
2.构成：关联词+简单句
3.引导主语从句的关联词有三类：
（1）从属连词that.如：That they were in truth sisters was clear from the facial resemblance between them.
很明显，她们确是亲姐妹，她们的脸型很相似。
（2）从属连词whether.如：
Whether he’ll come here isn’t clear.他是否会来这里还不清楚。
（3）连接代词who，whom，whose，what，which，whoever，whatever，whichever
连接副词 where，when，how，why.如：
What she did is not yet known.她干了什么尚不清楚。
