英语从句的讲解视频

⑴ 有什么详解英语句子成分的视频吗通俗易懂的，说的也比较好。求推荐！！！感激不尽！

中文中 主语是动作的执行者，比如“我吃饭”中“我”是主语 谓语是执行的动作版，那上边的例子来权说就是“吃” 宾语就是动作的承受者，“饭” 而定语起修饰作用，比如“我是一个很帅的男生”“很帅的”就是定语，通常定语有“……的” 状语，顾名思意，是表示状态的。

⑵ 英语从句详细讲解最好能举些例子

定语从句：在句中做定语，修饰一个名词或代词，例：The boys who are playing football are from Class One.
主语从句：在复合回句中充当主答语的句子叫做主语从句。例：What we need are good doctors.
宾语从句：就是一个句子作动词或介词的宾语。例：They know (that) he is working hard.
表语从句：表语从句就是用一个句子作为表语。说明主语是什么或者怎么样。例：The question is when can he arrive at the hotel.
同位语从句：在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。例：I heard the news that our team had won．
状语从句:指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。例：He smiled as he stood up.

⑶ 讲解英语各种从句（高分！！！！）

首先你要了解各种从句的定义，在脑中形成印象，最好每种句子都记住一个例句，从而加深理解。在句子中起名词作用的句子叫名词从句 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
名词性从句：
1.主语从句
句子的主语由句子充当的句子是主语从句。
Which style is more acceptable(接受）hasn't been discussed yet。主语从句

2.宾语从句
在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句.
时态：
1.主句用一般现在时，从句可用任意时态。
2.主句用过去时，从句用过去某个时态。
3.主句用过去时，从句是真理时，只用一般现在时。
I don’t know if there will be a bus any more.
我不知道是否还会有公交车.
其中的if there will be a bus any more.是句子的宾语。
3.表语从句
句子的表语由句子充当。
That is which I gave you.表语从句 which I gave you在句子是表语。
4.同位语从句
The idea which I gave you is no bad.同位语从句 其中的 which I gave you所指的就是idea

定语从句：
1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。
注：关系代词有主语.宾语之分。一般whom作为宾语。
定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。主要由形容词担任。此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。
先行词：被定语从句修饰的名词、代词称为先行词。限定性定语从句:
He is a student who never fail in exams.
“who never fail in exams.”是定语修饰student

状语从句：
状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
[编辑本段]状语从句的种类
状语从句可分为：
1.时间状语从句；(adverbial clause of time)
2.地点状语从句；(adverbial clause of place)
3.原因状语从句；(adverbial clause of cause)
4.条件状语从句；(adverbial clause of condition)
5.目的状语从句；(adverbial clause of purpose)
6.让步状语从句；(adverbial clause of concession)
7.比较状语从句；(adverbial clause of comparison)
8.方式状语从句；(adverbial clause of manner)
9.结果状语从句。(adverbial clause of result)
如：Every time I listen to your advice, I get into trouble.
“Every time I listen to your advice”是时间状语。

这是我自己整理的，你参考下吧，加油！

⑷ 跪求 英语中八种从句详细讲解

1. 定语从句；. 时间状语从句；3. 地点状语从句；4. 条件状语从句；5. 同位语从句；6. 表语从句；7. 宾语从句；8. 主语从句；
名词性从句：在句子中起名词作用的句子叫名词从句 (Noun Clauses）. 名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句.
引导名词性从句的连接词可分为三类：
连接词：that,whether,if 不充当从句的任何成分）
连接代词：what, whatever, who, whoever, whom, whose, which.
连接副词：when, where, how, why
不可省略的连词：
1. 介词后的连词
2. 引导主语从句和同位语从句的连词不可省略.
That she was chosen made us very happy.
We heard the news that our team had won.
比较：whether与if 均为"是否"的意思. 但在下列情况下whether 不能被if 取代：
1. whether引导主语从句并在句首
2. 引导表语从句
3. whether从句作介词宾语
4. 从句后有"or not"
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末，用 it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.
由从属连词that引导的从句叫做名词性that-从句. That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。
1）名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如：
主语：That he is still alive is sheer luck. 他还活着全靠运气.
宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去.
表语：The fact is that he has not been seen recently. 事实是近来谁也没有见过他.
同位语：The fact that he has not been seen recently disturbs everyone in his office. 近来谁也没有见过他,这一事实令办公室所有的人不安.
形容词宾语：I am glad that you are satisfied with your job. 你对工作满意我感到很高兴.
2）That- 从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure. 很清楚,整个计划注定要失败.
It's a pity that you should have to leave. 你非走不可真是件憾事.

⑸ 英语从句讲解

总结
从句（Subordinate Clause）是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、when等引导词（Connective）引导的非主句部分。
[编辑本段]分类
从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；后两类定语从句和状语从句功用相当于形容词，称为形容词性从句。状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句。
1.主语从句（Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
2.表语从句（Predicative Clause）：用作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大都一样。
3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
[编辑本段]宾语从句

第一部分

一.、定义：
宾语从句就是一个句子作动词或介词的宾语。
二、学习宾语从句要抓住三要素：连接词、语序和时态。
连接词一般都是that(指事务或人),which（指事）,who（指人）
1．从句为陈述句，常选择连接词that或将that省略，直接与主句相连。
2．从句为一般疑问句，常选择连接词if或whether。在whether…or not结构中不能用if替换。
3．从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代、副词作连接词。
★当who为主语时，句式为：who+谓语+其他
判断时态情况：
1.主句是一般现在时，从句为各种时态情况
2.主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时
3.主句是一般将来时，一般从句为一般现在时（“主将从现”）
例题：
〈1. The teacher told the children that the sun＿＿＿＿ round.
A. was B. is C. were D. are
〈2. I believe that our team＿＿＿＿ the basketball match.
A. win B. won C. will win D. wins
〈3. I don’t know＿＿＿＿ to visit the old man.
A. whether B. if C. that D. who
〈4.The soldiers soon reached( )was once an old temple( )the villagers used as a school.
A.which;where B.what;which C.where;which D.what;where
答4：选B，动词reach后接宾语从句，从句缺少宾语，where不可，which引导宾语从句时表疑问含义“哪一个…”而此句中并非疑问含义，不知道哪一座庙宇，而是用what从句表陈述含义，意“过去的一座旧庙宇”；temple后为对其修饰的定语从句，用关系代词which代替，并在从句中作动词used的宾语，use sth. as…“把…用作…
宾语从句，在复合句中作宾语，位于及物动词后；
Tell him which class you are in ．
Do you know what he likes？
(1)主、从句时态一致：
主句谓语过去时，从句相应过去时；
He answered that he was listening to me.
主句谓语现在时，从句时态任所需；
He says (that) he will leave a message on my desk.
They know (that) he is working hard.
具体过去永不变，真理格言现在时；
He told me that he was born in 1980.
Father told me that practice makes perfect .
（2）否定前移，及完成反意问句；
在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意疑问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称）
I don't think you are right ,are you ?
I don't believe they have finished their work yet,have they ?
（3）在表示建议 suggest , advise
要求demand 、desire、require、request、propose；
决定 decide; 命令 order、command; 坚决主张 insist;
等动词后跟宾语从句，用（should）+v．（虚拟语气）
eg． I suggested that you（should）study hard．
He ordered that we should go out at once．
（4）如果宾语从句后有宾语补足语，用it作形式宾语，把宾语从句后置
eg．You may think it strange that he would live there．
（5）宾语从句that常可省略，但在以下情况下不能省略
A．当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。
eg．I believe（that）you have done your best and that things will get bet?鄄ter．
B．当it作形式宾语时
eg．She made it clear that she had nothing to do with him．
C．当宾语从句前置时
eg．That our team will win，I believe．
三、分类
A 、作动词的宾语:
eg．I heard the news
I 主语 heard 谓语动词 the news.名词作宾语
I主语 heard 谓语动词 that he would come here later on.一个句子作宾语---宾语从句
B 、作介词的宾语:
eg．He said nothing about this plan 。
He主语 said 谓语动词 nothing 代词作动词的宾语 about 介词 the plan. 名词作介词的宾语
四、带有宾语从句的复合句的构成:
带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。连接词有：that(可省略)，what, who, when, where, why, which, if, whether, how.
五、注意：
A 宾语从句必须用陈述语序。
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
B 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
Bad: He left whether we should continue this project to my judgment.
Good: He left it to my judgment whether we should continue this project.
C 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.
Good: I don’t think he likes the English teacher.
D False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner.
4.同位语从句（Appositive Clause）： 与先行词同位或等同的从句叫作同位语从句。其关联词多为that。
5.定语从句（Attributive Clause）：用作定语的从句叫定语从句。定语从句一般皆放在被它所修饰的名（代）词之后，这种名（代）词就叫作先行词（Antecedent）。引导定语从句的关联词为关系代词(或称引导词、关系词等）。关系代词在定语从句中可用作主语、宾语、定语等；关系副词在定语从句中用作状语。
①引导定语从句的关联词有who, whom, whose, that, when, where, why 和 which. 在非限制定语从句中, 只可用which, who, whose, where , when., 如果指代前面整个句子, 多用which.

十、宾语从句的时态和语序
当主句为现在时或将来时的时候,宾语从句的时态一般不受主句的时态所影响。
当主句为过去时的时，细分为一下几种情况：
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
例句：
I only knew he was studying in a western country,but I didn’t know what country he was in.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.

②从句过去完成时表示该动作发生在主句谓语动作之前
例句：
He told me that he had told Mary about the meeting already.
他告诉我他已经把有关会议的事情告诉的了Mary.
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
例句：
The reporter asked if the government would take necessary measures to put down the to-do.
记者问政府是否会采取必要的措施镇压骚乱.
★如果从句是一个客观真理,那么从句的时候不根据主句的时态而变化
例句：
The teacher said that the moon goes around the earth yesterday.
老师昨天说月亮绕着地球转.
★当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
例句：
Who do you think the public might choose as their favorite singer this year?
你认为今年公众会选谁为他们最喜欢的歌手。
[编辑本段]同位语从句
同位语从句用法比较"固定",把关键的几个词背下来（下面这个材料供参考）：
一、在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。如：
I heard the news that our team had won．我听到了我们队获胜的消息。
I had no idea that you were here．我不知道你在这里。
二、可以跟同位语从句的名词通常有news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility等。如：
I’ve come from Mr wang with a message that he won’t be able to see you this afternoon． 我从王先生那里来，他让我告诉你他今天下午不能来看你了。
三、英语中引导同位语从句的词通有连词 that，whether，连接副词 how,when,where等。（注：if,which 不能引导同位语从句。）如：
l have no idea When he will be back．我不知道他什么时候回来。
He must answer the question whether he agrees to it or not.
他必须回答他是否同意这样一个问题。
四、有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。 如：
Several years later，word came that Napoleon himself was coming to inspect them．
几年以后，有消息传来说拿破仑要亲自视 察他们。
The thought came to him that maybe the enemy had fled the city．
他突然想起可能敌人已经逃出城了。
五、同位语从句与定语从句的区别。
1、同位语从句与前面的名词是同位关系，即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系，即限定它前面的名词范围，或补充一些情况。如：
The news that l have passed the exam is true．我通过了考试这一消息是真的。
（同位语从句，即从句所表达的意思就是前面名词的内容。）
The news that he told me just now is true．他刚才告诉我的消息是真的。
（定语从句，从句对前面名词起修饰限制作用，即“他告诉我的”那个消息，而不是别的消息。）
2、引导同位语从句的that是连词，在从句中不充当任何成份，而引导定语从句的that是关系代词，除起连接作用外，还在从句中充当主语、宾语或表语等。如：
The idea that computers can recognize human voices surprises many people.
计算机能够识别人的声音的想法使许多人感到惊奇。（that在从句中不充当任何成份。）
The idea that he gave surprises many people．他提出的观点令许多人感到吃惊。
（that在从句中作gave的宾语。）
一个名词(或其它形式)对另一个名词或代词进行修饰，限定或说明，这个名词(或其它形式)就是同位语。同位语与被它限定的词的格要一致，并常常紧挨在一起。
1) 非独立的同位语：常出现在被限定词前
Bruce Lee (姓名) 李小龙
Graf Schmidt (称号，浑名) 施密特伯爵
Doktor Wang (职称，头衔) 王博士
Uncel Liu (亲戚的称呼) 刘叔叔
die Stadt Shanghai (类属名称) 上海市
the Province Hebei (类属名称) 河北省
das Jahr 2000 (类属名称) 2000 年
three Kilo tomato (度量名称) 三公斤西红柿
the University Bremen (专有名词) 不来梅大学
希望对你有帮助。

⑹ 英语从句的讲解!要详细的!

定语从句概要：
（这是有关定语从句的精要介绍，涵盖了有关定语从句的各个方面，供参考：）

引导定语从句的关联词包括关系代词和关系副词。关系代词有that, which, whose, who, whom, as；关系副词有when, where, why。关系代词和关系副词在定语从句中都充当一定的句法成份。关系代词在从句中充当动词的宾语时一般可以省略。
关系代词的选用比较复杂，受下列条件的制约：
(1) 要看先行词是指人还是指物，
(2) 要看关系代词在从句中句法功能，
(3) 要看定语从句是限定性的还是非限定性的。

在定语从句中充当的成分
↓ 用于限定性或非限定性从句 只用于限定性从句
指人 指物 指人或指物
主语 who which that
宾语 whom which that
谓语 whose whose (of which)
That 只能用在限定性定语从句中，而who, whom, which, which 既可用于限定性定语从句中，也可用于非限定性定语从句。
I know that he is a man who means what he says.
I know that he is a man that means what he says. 【我知道他是一个守信用的人。】

The gentleman whom she met addressed her with courtesy.
The gentleman that she met addressed her with courtesy. 【她遇到的那位先生很有礼貌地向她打了招呼。】
The gentleman she met addressed her with courtesy.（在从句中充当动词宾语的关系代词，可以省略。）

The watch which was lost has been found.
The watch that was lost has been found. 【丢了的表找到了。】

Here is the material which you need. (注：现代美语中不允许这样用)
Here is the material that you need.
Here is the material you need. 【你要的材料在这儿了。】

You are the only one whose advice he might listen to. 他也就是听你的话吧。

关系副词的选用相对来说比较简单，如果先行词是表示时间的名词，如time, day 等，则用when, 如先行词为表示地点的名词，如place, house, area 等等，则选用where。如果先行词为reason 则选用why

I will never forget the mountain village where I spent my childhood.
I will never forget the mountain village in which I spent my childhood.
我永远也不会忘记我度过童年的那个小山村。

I don’t know the reason why he did that.
I don’t know the reason for which he did that. 【我不知道他为什么这么做。】

当先行词是all, something, nothing 等不定代词时，或者先行词的前面有first, last, only, few, much, some, any, no 等词修饰时，或者先行词的前面有最高级修饰时，一般只用that 而不用which 来引导定语从句：
I have explained everything that I can to you.
I have explained everything I can to you. 【我已经尽一切可能把事情向你解释得一清二楚。】

This is the most beautiful campus that I have ever been to.
This is the most beautiful campus I have ever been to. 【这是我见到的最美丽的校园。】

That’s all that I know.
That’s all I know. 【我知道的就是这些。】

Can you tell me something that you know?
Can you tell something you know? 【你能把你知道的一些情况告诉我吗？】

There is nothing that I cannot tell you.
There is nothing I cannot tell you. 【我没有什么不能告诉你的事情。】

The first thing that we should do is to work out a plan.
The first thing we should do is to work out a plan. 【我们应该做的头一件事就是订一个计划。】

The last place that we visited was the farm.
The last place we visited was the farm. 【我们最后参观的地方是农场。】

还有一种定语从句，它的结构是：the same ….. as…, such … as
这里的as 可以指人或物，这里的as 引导的是限定性定语从句：
Such furniture as is very popular is expensive. 一种很受欢迎的家具价钱昂贵。
We have successfully done the same experiment as you did. 你做过的那个试验我们已经成功地做完了。
It wasn’t such a computer as the advertisement had promised. 这种电脑可不是广告中说的那种电脑。

限定性定语从句与主句关系密切，为句中不可缺少的部分，如去掉，主句意思就不完整了。而非限定性定语从句与主句关系松散，如果去掉了，主句内容仍然完整。在书面语中非限定性定语从句一般补逗号隔开。非限定性定语从句一般不用that 引导。引导非限定性定语从句的关系词不可省略。
His speech, which bored everyone, went on and on. 他的讲话没完没了，真让人烦。
The general’s daughter, whose name is Jane, gave me a sweet smile.
将军的女儿名叫珍妮。她冲我笑了笑，笑得好甜啊。

非限定性定语从句中，先行词也可以是整个句子，一般用which 或as 来引导定语从句，which在从句中可充当主语、宾语等，as 在从句中一般只充当主语，which 与as 引导这类定语从句的区别在于：which 只能放在句子当中或句子末尾，而as 的位置比较灵活，可以放在句子当中、句子末尾，也可以放在句首。
As is known to all, too much stress can cause disease.
Too much stress can cause disease, as is known to all.
Too much stress can cause disease, which is known to all. 【众所周知，压力太大了，人会得病的。】

Water consists of hydrogen and oxygen, which is known to all.
Water consists of hydrogen and oxygen, as is known to all. 【众所周知，水是由氢和氧组成的。】

关系代词在定语从句中有时也作介词的宾语。如果介词被置于关系代词前，一般只用介词加which 或介词加whom，而不用介词加that来引导定语从句。如果介词被置于从句句末，则可以使用that来代替which或whom，这时的that可以省略。
This is the ring on which she spent 1,000 dollars. 这就是她花了一千美元买的那枚戒指。

One of my colleagues whom you are familiar with will come today.
One of my colleagues that you are familiar with will come today.
One of my colleagues you are familiar with will come today.
我的一个同事，就是你非常熟悉的那个人，今天要过来。

⑺ 英语从句具体讲解

总结
从句（Subordinate Clause）是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、when等引导词（Connective）引导的非主句部分。
[编辑本段]分类
从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；后两类定语从句和状语从句功用相当于形容词，称为形容词性从句。状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句。
1.主语从句（Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
2.表语从句（Predicative Clause）：用作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大都一样。
3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
[编辑本段]宾语从句

第一部分

一.、定义：
宾语从句就是一个句子作动词或介词的宾语。
二、学习宾语从句要抓住三要素：连接词、语序和时态。
连接词一般都是that(指事务或人),which（指事）,who（指人）
1．从句为陈述句，常选择连接词that或将that省略，直接与主句相连。
2．从句为一般疑问句，常选择连接词if或whether。在whether…or not结构中不能用if替换。
3．从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代、副词作连接词。
★当who为主语时，句式为：who+谓语+其他
判断时态情况：
1.主句是一般现在时，从句为各种时态情况
2.主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时
3.主句是一般将来时，一般从句为一般现在时（“主将从现”）
例题：
〈1. The teacher told the children that the sun＿＿＿＿ round.
A. was B. is C. were D. are
〈2. I believe that our team＿＿＿＿ the basketball match.
A. win B. won C. will win D. wins
〈3. I don’t know＿＿＿＿ to visit the old man.
A. whether B. if C. that D. who
〈4.The soldiers soon reached( )was once an old temple( )the villagers used as a school.
A.which;where B.what;which C.where;which D.what;where
答4：选B，动词reach后接宾语从句，从句缺少宾语，where不可，which引导宾语从句时表疑问含义“哪一个…”而此句中并非疑问含义，不知道哪一座庙宇，而是用what从句表陈述含义，意“过去的一座旧庙宇”；temple后为对其修饰的定语从句，用关系代词which代替，并在从句中作动词used的宾语，use sth. as…“把…用作…
宾语从句，在复合句中作宾语，位于及物动词后；
Tell him which class you are in ．
Do you know what he likes？
(1)主、从句时态一致：
主句谓语过去时，从句相应过去时；
He answered that he was listening to me.
主句谓语现在时，从句时态任所需；
He says (that) he will leave a message on my desk.
They know (that) he is working hard.
具体过去永不变，真理格言现在时；
He told me that he was born in 1980.
Father told me that practice makes perfect .
（2）否定前移，及完成反意问句；
在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意疑问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称）
I don't think you are right ,are you ?
I don't believe they have finished their work yet,have they ?
（3）在表示建议 suggest , advise
要求demand 、desire、require、request、propose；
决定 decide; 命令 order、command; 坚决主张 insist;
等动词后跟宾语从句，用（should）+v．（虚拟语气）
eg． I suggested that you（should）study hard．
He ordered that we should go out at once．
（4）如果宾语从句后有宾语补足语，用it作形式宾语，把宾语从句后置
eg．You may think it strange that he would live there．
（5）宾语从句that常可省略，但在以下情况下不能省略
A．当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。
eg．I believe（that）you have done your best and that things will get bet?鄄ter．
B．当it作形式宾语时
eg．She made it clear that she had nothing to do with him．
C．当宾语从句前置时
eg．That our team will win，I believe．
三、分类
A 、作动词的宾语:
eg．I heard the news
I 主语 heard 谓语动词 the news.名词作宾语
I主语 heard 谓语动词 that he would come here later on.一个句子作宾语---宾语从句
B 、作介词的宾语:
eg．He said nothing about this plan 。
He主语 said 谓语动词 nothing 代词作动词的宾语 about 介词 the plan. 名词作介词的宾语
四、带有宾语从句的复合句的构成:
带有宾语从句的复合句就是用连接词把一个主句和一个宾语从句连接在一起。连接词有：that(可省略)，what, who, when, where, why, which, if, whether, how.
五、注意：
A 宾语从句必须用陈述语序。
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
B 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
Bad: He left whether we should continue this project to my judgment.
Good: He left it to my judgment whether we should continue this project.
C 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.
Good: I don’t think he likes the English teacher.
D False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner.
4.同位语从句（Appositive Clause）： 与先行词同位或等同的从句叫作同位语从句。其关联词多为that。
5.定语从句（Attributive Clause）：用作定语的从句叫定语从句。定语从句一般皆放在被它所修饰的名（代）词之后，这种名（代）词就叫作先行词（Antecedent）。引导定语从句的关联词为关系代词(或称引导词、关系词等）。关系代词在定语从句中可用作主语、宾语、定语等；关系副词在定语从句中用作状语。
①引导定语从句的关联词有who, whom, whose, that, when, where, why 和 which. 在非限制定语从句中, 只可用which, who, whose, where , when., 如果指代前面整个句子, 多用which.

② 当引导定语从句的先行词前有all, any, no, little, much, very first 等词, 或先行词前为形容词最高级所修饰时,或先行词为all, anything, nothing, something, everything 时,从句的引导词只能用that.

③as 可做引导词引导定语从句, 多和such, the same 连用. As 引导的定语从句也可修饰整个句子, 既可放在先行词后,也可放在句子开头.
例句：

十、宾语从句的时态和语序
当主句为现在时或将来时的时候,宾语从句的时态一般不受主句的时态所影响。
当主句为过去时的时，细分为一下几种情况：
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
例句：
I only knew he was studying in a western country,but I didn’t know what country he was in.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.
He asked me if I was reading the story “The Old Man and the Sea ”when he was in.
他问我他进来的时候我是否正在读<老人与海>.
②从句过去完成时表示该动作发生在主句谓语动作之前
例句：
He told me that he had told Mary about the meeting already.
他告诉我他已经把有关会议的事情告诉的了Mary.
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
例句：
The reporter asked if the government would take necessary measures to put down the to-do.
记者问政府是否会采取必要的措施镇压骚乱.
★如果从句是一个客观真理,那么从句的时候不根据主句的时态而变化
例句：
The teacher said that the moon goes around the earth yesterday.
老师昨天说月亮绕着地球转.
★当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
例句：
Who do you think the public might choose as their favorite singer this year?
你认为今年公众会选谁为他们最喜欢的歌手。
[编辑本段]同位语从句
同位语从句用法比较"固定",把关键的几个词背下来（下面这个材料供参考）：
一、在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。如：
I heard the news that our team had won．我听到了我们队获胜的消息。
I had no idea that you were here．我不知道你在这里。
二、可以跟同位语从句的名词通常有news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility等。如：
I’ve come from Mr wang with a message that he won’t be able to see you this afternoon． 我从王先生那里来，他让我告诉你他今天下午不能来看你了。
三、英语中引导同位语从句的词通有连词 that，whether，连接副词 how,when,where等。（注：if,which 不能引导同位语从句。）如：
l have no idea When he will be back．我不知道他什么时候回来。
He must answer the question whether he agrees to it or not.
他必须回答他是否同意这样一个问题。
四、有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。 如：
Several years later，word came that Napoleon himself was coming to inspect them．
几年以后，有消息传来说拿破仑要亲自视 察他们。
The thought came to him that maybe the enemy had fled the city．
他突然想起可能敌人已经逃出城了。
五、同位语从句与定语从句的区别。
1、同位语从句与前面的名词是同位关系，即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系，即限定它前面的名词范围，或补充一些情况。如：
The news that l have passed the exam is true．我通过了考试这一消息是真的。
（同位语从句，即从句所表达的意思就是前面名词的内容。）
The news that he told me just now is true．他刚才告诉我的消息是真的。
（定语从句，从句对前面名词起修饰限制作用，即“他告诉我的”那个消息，而不是别的消息。）
2、引导同位语从句的that是连词，在从句中不充当任何成份，而引导定语从句的that是关系代词，除起连接作用外，还在从句中充当主语、宾语或表语等。如：
The idea that computers can recognize human voices surprises many people.
计算机能够识别人的声音的想法使许多人感到惊奇。（that在从句中不充当任何成份。）
The idea that he gave surprises many people．他提出的观点令许多人感到吃惊。
（that在从句中作gave的宾语。）
一个名词(或其它形式)对另一个名词或代词进行修饰，限定或说明，这个名词(或其它形式)就是同位语。同位语与被它限定的词的格要一致，并常常紧挨在一起。
1) 非独立的同位语：常出现在被限定词前
Bruce Lee (姓名) 李小龙
Graf Schmidt (称号，浑名) 施密特伯爵
Doktor Wang (职称，头衔) 王博士
Uncel Liu (亲戚的称呼) 刘叔叔
die Stadt Shanghai (类属名称) 上海市
the Province Hebei (类属名称) 河北省
das Jahr 2000 (类属名称) 2000 年
three Kilo tomato (度量名称) 三公斤西红柿
the University Bremen (专有名词) 不来梅大学
