英语中几大从句的用法总结
⒈主语从句
⑴主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的
句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that.
..

⑵what引导的主语从句表示“...的东西时”，一般不用it
作形式主语。
*What we lack is experience.
⑶what,who,when,why,whether等词含有各自的疑问
意义，但它们引导的主语从句，都用陈述语序。
*How the plan is to be carried out should be discus
sed again.
*I did know why I felt like crying.
⒉宾语从句
⑴宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young peo
ple
would say about friendship.
*He is certain that watching so much television is n
ot
good for children.
*This article is well-written except that it is a bit
too long.
⑵宾语从句后如有宾补，要用形式宾语it来代替，而把
宾语从句移至宾补之后。
*He has made it clear that he would not change his
mind.
⑶在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，
宾语从句则变成肯定形式。
*He didn't think that the money was well spent.
⒊表语从句
⑴表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how 等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，
不可用because.

hat
there is no one common type of life in America.

mind.
4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用
whether/who/when/
Where/what/why/how等引导。常见的先行名词有
fact/idea/
Belief/news/hope/conclusion/evidence/suggestion/
order/
Problem/report,/decision.有时由于谓语较短，将同位

*She finally made the decision that she would joi
n
the fashion show.
*I had no idea how many books I could borrow at a
time.
*The news came that their team had won the
championship.
5.定语从句
【定语从句所修饰的先行词可以是名词或代词，也可以
是一个句子。定语从句通
常位于先行词之后，由关系代词或关系副词引导】
⑴限制性定语从句【限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有
who/whom/whose/which/that等who/whom/
whose用于指人，whose有时也可指物，相当于
of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等】
*The computers and cables which make up the
Internet are owned by people and organizations.
*Those who live alone or who are sick may have tro uble in getting close to other people.
*The girl whose parents died in an accident is livin
g with her grandmother.
1)当先行词是
all/anything/everything/something/nothing等不定代词或先行词前有first/last/any/few/much/some/no/only以及形容词最高级修饰时，只能用关系代词that引导从句。
*That is all that I've heard from him.
*He's the first person that I'm going to interview thi
s afternoon.
2)在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom 引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。
*This is one of those things with which we have to
put
up.
*This is one of those things (which\that) we have to
put up with.
3)引导定语从句的关系副词有when/where/why等。关系副词在从句中作状语，意义上相当于一个“介词+which”
的结构。
*Even in comic books where(=in which) there are n o words,the stories are fully expressed through the dr
awings.
*No one knows the reason why(=for which) he was
so angry that day.
⑵非限制性定语从句【非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略】
*Every object has a gravitational pull,which is rathe
r like magnetism.
⑶“介词+which\whom\whose”引导的定语从句
【“介词+which\whom\whose”可引导限制性定语从
句，也可引导非
限制性定语从句，该结构中介词的选择取决于从句谓语
动词的固
定搭配，或先行词的习惯搭配】
*This is the computer on which he spent all his
savings
*It is written by a person with whom we are all
familiar.
⑷as引导的定语从句
【as引导的定语从句主要用于“such...as”及
“the same...as”
的结构中，代替先行词是人或物的名词。as引导非限制
性定语句
时，代替整个主句，从句可位于主句之前、之后或中间】*These are not such problems as can be easily solv
ed.
(as代替先行词problems)
*As is mentioned above,no single company or grou
p can
Control what happens on the Internet.(as代替主语)
6.状语从句

1）
when/whenever/while/as/after/before/since/till/until/on
ce等。
*We have learnt quite a lot about it since we cam
e
here.
2)as soon as/hardly(scarcely)...when/no sooner...th an/each(every) time/the moment/immediately(that)等。

for fear that/lest等，从句常使用
may/might/can/could/
would等情态动词。

atch
the first bus to the railway station.
⑷条件和让步状语从句
if/unless,as(so) long as/on condition that/in case/provi ded(providing) that/supposing等。
*As long as you have the right equipment,you ca
n
use a telephone line to transmit computer data.
2)引导让步状语从句
though/although/whether/even though/
even if/no matter
what(when,how...)/whatever(whenever, wherever,however....)等。Though/even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。
*No matter what you may say,I would not chan ge my mind. *Young as he is,he is quite experience
d in this work.
(=though he is young)
*Child as he is,he can speak English fluently.
(=though he is a child)

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。

英语中六大从句用法总结 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation.

I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that 常可省略。如主句主语为reason,只能用that引导表语从句，不可用because. Perhaps the most important thing to remember is that there is no one common type of life in America. The reason why so many people died there is that there were not enough food supplies.
时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.

A．Having exposed B．Being exposed C．To expose D．Exposed 【答案】B 【解析】 【详解】 考查动名词。句意：暴露于核辐射中甚至很短时间都会影响人体的基因。分析句子成分发现even for a short time是插入语，may influence是谓语，前面的部分应该是主语，be exposed to“暴露于”，要用动名词Being exposed to。故B选项正确。 4．The lecture, _______at 7:00 pm last night, was followed by an observation of the moon with telescopes. A．starting B．being started C．to start D．to be started 【答案】A 【解析】 选A start与逻辑主语the lecture之间为主动关系，故排除B、D两项。不定式作定语时，常表示动作尚未发生，故排除C项，此处用现在分词作后置定语，表示主动。 第四步：根据与谓语动词的先后关系确定时态 非谓语动词表示的动作发生在谓语动词表示的动作之前用过去分词或v.-ing形式/不定式的

Perhaps the most important thing to remember is that there is no one common type of life in America. The reason why so many people died there is that there were not enough food supplies. It looks as if successful international cultural communication will make the world smaller. 4.同位语从句由于先行名词的意引导，一般用连词that同位语从句用于对前面出现的名词作进
要注意主句和从句的时态大多都要保持一致。） 1.由when, while, ,just ,just as, as，after, before, since, until, as soon as,引导的时间状语从句。例如： When you think you know nothing, then you begin to know something. 当你以为自己一无所知的时候，你就是在开始知道一些事物了。 When truth is buried under the ground ，it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it. 当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！ Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。 Our headmaster laughed as she spoke. 我们的校长边谈边笑。 主要时态：主现从不现；主过从四过；主将从现。 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；动作既可以 和主句的动作同时发生，又可以在主句的动作前后发生。并且when有时表示“就在 那时”。 例如： When she came in, I stopped eating.她进来时，我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时，我常常为他担水。（延续性的动词） We were about to leave when he came in.我们就要离开，就在那时他进来了。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。 例如： While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生) 。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。（对比） 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。例如： We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）As we were 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）
where引导的地点状语从句用法总结归纳 1、where 在地点状语从句中，除指地点外，还可指处境等。 eg. I'm unsatisfied with where I live. 我对自己住的地方特不 满意。 2、有时地点状语从句中的某些词能够省略。 eg. Fill in the blanks with the given phrases. Change the form where necessary. 用所给的短语填空，必要的地方能够改变其 形式。 3、地点状语从句一般置于主句之后。 eg. Keep it where you can see it. 把它放在你看得见的地方。 4、where一般表示一个确定的但非特指的地点。 eg. The school was built where there had once been a cemetery. 学校建在一座墓园的旧址。 5、wherever, anywhere 和 everywhere 表示“任何地方”。 eg. No matter where you now are in writing, you can improve with practice. 不管你在写作上你处于什么水平，练习都能帮你提升。 6、where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 eg. Go back where you came from.你从何处来到何处去。(where引导地点状语从句) Go back to the country where you came from.你从哪个国家来了 就回哪去。(where引导定语从句，修饰place)
英语系动词用法小结 重庆市奉节中学何朝平 英语系动词的功能主要是把表语（名词、形容词、某些副词、非谓词、介词短语、从句）和它的主语联系在一起，说明主语的属性、特征或状态。它有自己的但不完全的词义，不能在句中独立作谓语，必须和后面的表语一起构成句子的谓语。它虽是虚词，但是其用法是复杂的，而且不可忽视。许多英语初学者会因此出现这样那样的错误，然而许多语法书却没作专门系统的介绍。因此，我们有必要小结一下英语系动词用法，以便大家参考。我想从以下四个方面归纳一下英语系动词的用法：I、常见系动词错误及其成因；II、系动词分类；III、系动词用法应注意的8个问题；IV、系动词与高考及其练习。 I、常见系动词错误及其成因： 学英语的中国学生在使用系动词时会碰到以下两个问题：一是有漏掉系动词的倾向性，因为汉语中无系动词，如： I afraid he won’t come tomorrow(am) 二是误用系动词，如： His hair changed grey .(混淆了change 与turn，grow) His hands feel coldly.(feel本身作系动词与实义动词的差别不清) 这主要是因为学生没有把英语中的系动词与实义动词的用法区分开来。二者结构区别如下表，其后所接词性不尽相同，成份也不同。
II.系动词分类： 一、根据系动词后所跟结构，我们可以把英语系动词分为两大类：完全系动词（其后只能跟表语的动词，如be, seem）和半系动词（其后既可跟表语作系动词用法，也可跟宾语或状语作实义动词用，如look） He looked sad at the news.（“看起来”，系动词用法）例如：1） He looked sadly at the boy.(“看着”，实义动词用法) He looks a clever boy .（“看起来”，系动词用法） 2） He looks at a clever boy.（“看着”，实义动词用法）在英语中，某一动词是多义词，既有实义动词用法，又有系动词用法。学生务必弄清其二者区别。切忌把二者混为一谈，这也是会考、高考常见考点。此类常见易混词有： change listen look touch ①turn ②hear ③see ④ become sound seem feel eat continue last remain ⑤⑥⑦continue ⑧stay taste keep remain leave 二、根据系动词的意义，我们把英语系动词分为四类： A．五大感官系动词B．状态系动词 C．动态系动词D．双谓语系动词 A．五大感官系动词，描述一种感官性质。由实义感官动词变化而来，都是半系动词。 1．look“看起来像是”，后接adj.、n.、分词、介词短语、不定式等。
英语中六大从句用法总结 从句是指用于复合句中担当某个句子成分的主谓结构。虽说从句自身的句子结构是完整的，但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。按其所能表达的意义而言,它相当于一个词或是一个词组. 按从句的句子功能划分（也就是按从句在句子中所担任的成分来划分），从句可分为：主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句。 1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。 What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
