英文连接词像胶水一样将相关联的句子连接起来,所以又被称为“胶水词”,胶水词就像英语的骨架一样重要,学会了胶水词,同时拥有词组的累积,你就可以轻松灵活的造出任何需要的长句,让你的英文交流如鱼得水。下面让我们来熟悉一下常用的英语连接词包括哪些:

(1)表示承接的过渡词:also,and,and then,too,in addition,furthermore,moreover,what's more, again,on top of that,another,first,second,third,fourth等。

(2)表示时间顺序的过渡词:now,then,before,after,afterwards,earlier,later,immediately,soon,next,in a few days,gradually,suddenly,finally等。(但是你可以感受到这些词是副词,所以原词条对于“连接词”即连词是错误的)

(3)表示空间顺序的过渡词:near(to),far(from),in front of,behind,beside,beyond,above,below,to the right/left,around,outside等。

(4)表示比较的过渡词:in the same way,just like,just as等。

(6)一方面,另一方面:on the one hand,on the other hand,for one thing,for another等。

(7)表示结果和原因的过渡词:because,since,so,as a result,therefore,then,furthermore,otherwise等。(as a result ,therefore, thus并不是连词而是副词,所以经常是放句首,用逗号与后面句子隔开)

(8)表示目的的过渡词:for this reason,for this purpose,so that,in order to等。

(9)表示强调的过渡词:in fact,indeed,surely,necessarily,certainly,without any doubt,truly,to repeat,above all,most important等。

(11)表示总结的过渡词:in a word,above all,,all in all,finally,at last,in conclusion,as I have shown,in another

word,in brief,in short,in general,on the whole,as has been stated,last but not least, in addition等。

1、并列连词

and 和,那么,渐渐;

or 或,否则,不管是…,还是;

but 但是,而是,的确…但;nor 也不

so 也是,因此,所以,那么,这样看来;

for 因为(表示推测),由于;

2、相关连词

both A and B 既是A又是B;

either A or B 不是A 就是B;

neither A nor B 既不是A也不是B ,两者皆非;

四、强调句

由于强调句是对句子主语、宾语、状语等非谓语成分的强调,而不是修饰,通常不当做从句对待

其句式为:It is/was ……. (被强调的句子成分) + that (被强调部分为人时用who)…….(原句剩余部分)原句:Tom usually plays basketball on weekends with his best friend.

强调主语:It is Tom who usually plays basketball on weekends with his best friend.

强调宾语:It is basketball that Tom usually plays on weekends with his best friend.

强调状语:It is on weekends that Tom usually plays basketball with his best friend.

强调状语:It is with his best friend that Tom usually plays basketball on weekends.

强调谓语:通常只需在谓语前添加助动词do/does/ did

Tom usually does play basketball on weekends with his best friend.

五、其他特别的从句

1、部分形容词后面带that从句,往往带有情感情绪的

I am sorry that…. I am afraid that…… I am so glad that…..

2、类似主语从句的情况:

It is a pity that….. It is a shame that…

It is/was time that …..过去式….. It is time that we went to the meeting. = It is time to go to the meeting.

3、时间与方式的个别情况:

the moment that (that可省略)….. The moment that he came in we started the meeting.

the way that (that可省略)….. We don’t like the way that he treats others.

复合句--三大从句

名词性从句 在句子中起名词作用的句子叫名词性从句(NounClauses)。名词性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,名词性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。 I.引导名词性从句的连接词 引导名词性从句的连接词可分为三类: 从属连词(6个):that(无意义) whether, if(均表示“是否”,表明从句内容的不确定性;if只能用来引导宾语从句)as if ,as though(均表示“好像”,“似乎”)because (表示“因为”) 以上在从句中均不充当任何成分,后三个只能用来引导表语从句。 连接代词(9个): what,whatever,who,whoever,whom,whomever,whose,which,whichever 连接副词(7个):when, where, how, why, whenever, wherever, however II.主语从句 在句子中充当主语的名词性从句叫主语从句。 What he wants to tell usis not clear.他要跟我们说什么,还不清楚。 Who will win the matchis still unknown.谁能赢得这场比赛还不得而知。 Where the English evening will be heldhas not yet been announced. 英语晚会将在哪里举行,还没有宣布。 有时为避免句子头重脚轻,常用形式主语it代替主语从句放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。(what表示“……的事物”时引导的主语从句一般不后置。)

三大类从句的引导词

引导主语从句连词有that,whether,who,what,whatever等定义:如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句. 第一部分:常规主语从句,即句子在复合句中充当一个主语 (1)That he finished writing the composition in such a short time surprised me. (2)Whether we will go for an outing tomorrow remains unknown. (3)Who will be our monitor has't been decided yet. (4)Whom we must study for is a question of great importance. (5)What caused the accident remains unknown. (6)Whatever you did is right. (7)Whose watch was lost is unknown. (8)What we need is time. (9)What we need are good doctors. 小结: (1)引导主语从句连词有that,whether,who,what,whatever等 (2)连词位于句首不能省略 (3)主语从句大多数情况下视为单三,但也有例外,如例9 第二部分:为了防止句子头重脚轻,通常把形式主语it放在主语位置,真正主语搁置于句末 (1)It is certain that he will win the match. (2)It is true that he has made a very important discovery in chemistry. (3)It is very likely that they will hold a meeting.

三大从句

一.名词性从句 名词性从句相当于名词,一个从句在整个句子中充当名词的作用,它可以作为主句的主语、表语、宾语和同位语。 名词性从句主要分为四种:主语从句,表语从句,宾语从句,同位语从句。 1.Who will win the match is unknown. 2.I want to know what he has told you. 3. The fact is that he had won the game. 4. The news that we won the game is exciting. (一)宾语从句 宾语从句在复合句中做及物动词的宾语,或用作介词和某些表示心理活动的形容词后作宾语,或是用it 作为形式宾语代表宾语从句。 例:1. I think that it will be of no use. 2. It depends on whether the boss will agree to you or not. 宾语从句的连接词:that,(常用且一般可省略)who, what, whether/if(是否)which, whoever, whatever ,when, where, how, why. (连接词的选择要看从句的具体意思需要) 例:1. I know that you are a teacher. 2.I wonder if/ whether you are Mr Li. 3. Do you know what I will do next? 4. I can guess which team will win. 5. I don’t know when he will come. 6. I don’t know where he has gone. 7. They don’t know how they should help me. 8. Please give the book to whoever likes it. 注意: ①★宾语从句的语序一定是正常的语序,即陈述句的语序,先主语后谓语。 I don’t know who are you. (X) I don’t know who you are. (∨) ②★从句的时态需跟主句相配合。主句为一般现在时,从句可根据需要选择各种时态; 主句为一般过去时时,从句通常用过去的时态。 ③★介词后的宾语从句,引导词一般不用which,if,that,但可用what(常用,常常是充当从句的主语,宾语或表语),how, whether等引导。 ④★that在所有的名词性从句中都不充当成分,在宾语从句中that可以省略。(二)主语从句 1.Whose watch was lost is unknown. 2.What we need is time. 3.Whom we must study for is a question of great importance. 4.Whether we will go for an outing remains unknown. 5.That he finished writing the composition surprised us all. 1.主语从句的连接词: 1)从属连词(从句中不充当成分,只起连接作用):that,whether等. that 引导主语从句只起引导作用,本身无意义,在主语从句中不充当任何成分,但不能省略。注意: 已确定的事由that引导;没决定的事由whether引导.

初中英语三大从句

初中英语三大从句 定语从句: 定语是指在句子中用来修饰名词、代词的成分。 如:I will give my teacher a bunch of beautiful flower.(中beautiful就是定语) 定语从句是指在一个句子中作定语的句子,定语从句要放在所修饰的词后 如:I have met the doctor who is in the No.1 hospital. 定语从句的连接词: 连接代词:who、which、whom、whose、that 连接副词:when、where、why 状语从句: (1)时间状语从句:在一个句子中作时间状语的句子。 时间状语的连接词:when(当…时候) while(当…时候) as(当…时候) after(在…以后) before(在…以前) as soon as(一…就) since(自从…到现在) till /until(直到…才) by the time(到…为止)依旧是连接词后加陈述语序。 举例:when当…的时候(一般情况下主句是将来时的时候,从句要用一般现在时。) Mozart started writing music when he was four years old. (2)原因状语从句:在一个句子中作原因状语的句子。 连接词:由连词because, since, as引导, 也可由for, now that 等词引导。 举例:I didn’t go to school yesterday because I was ill. (3)条件状语从句:在一个句子中作条件状语的句子。 连接词:if如果, unless (=if not) 除非。(让步) 举例:If it doesn’t rain tomorrow, we will go hiking. (4)目的、结果状语从句 目的状语从句是指在一个句子中充当目的状语的句子。 结果状语从句是指在一个句子中充当结果状语的句子 目的状语从句连接词so that, so…that , in order that 引导。

三大从句语法

从句可分为三类:即名词性从句、形容词性从句(即定语从句)和副词性从(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 ,whose 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。 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” 例:Whether he will come is not clear。The fact is that he didn't go to the dinner party。 I don't know if he will attend the meeting。 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。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. 用it作形式主语的that—从句有以下四种不同的搭配关系: A It + be +形容词+ that—从句例:It is necessary that…有必要……It is important that…重要的是……It is obvious that… 很明显…… B. It + be + —ed 分词+ that-从句例如:It is believed that…人们相信……It is known to all that…从所周知……It has been decided that… 已决定…… C。It + be +名词+ that—从句例:It is common knowledge that………是常识It is a surprise that… 令人惊奇的是……It is a fact that… 事实是…… D. It +不及物动词+ that—分句例:It appears that…似乎……It happens that…碰巧……It occurred to me that… 我突然想起…… 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. The news that we are invited to the conference is very encouraging. 二、形容词性从句 引导定语从句的关联词包括:(1)关系代词:that,which, whose, who, whom,as; (2)关系副词: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分,关系代词在句中充当动词的宾语

三大从句:名词性从句状语从句定语从句

三大从句:名词性从句状语从句定语从句 高中英语主要要掌握三大从句。 分别是: 1、名词性从句(包括主语从句,宾语从句,表语从句,同位语从句) 2、状语从句(副词性从句,包括时间,地点,结果,目的,原因等) 3、定语从句(形容词从句) 名词性从句 1. 定义:从句在句子中充当名词。 1.分类:主语从句,宾语从句,表语从句,同位语从句。(从句在句中充当成份) 2.连接词: 1)连词:that(无意义,不充当成份),if/wether (无意义,是否),as if ,as though (好像,似乎) 2)连接代词:what(充当主,宾,表,什么),who(主宾表,指人),whom(宾,指人), which(主宾表,定,哪一个),whose(定语,谁的) 3)连接副词:when(时间状语,什么时候),where(地点状语,什么地方), why (原因状语,为什么),how (方式状语,怎么样,如何) 4)复合连词:whatever(不管什么),whoever(不管是谁),whichever(不管哪个),whomever(不管是谁),whenever(不管什么时候),wherever(不管什么地方), however(不管怎样) 一,主语从句 1.定义:从句在句中充当主语,常位于句首或者动词be动词之前 Eg:他获得一得奖一事使他很兴奋。That(不充当成份,无意思)he got the first price excited him. 她能来我们很高兴。That she was able to come made us happy.

我们是否能准时到达那儿还不确定. Whether we can get there on time is doubtful. 我们如何处理这个问题还未作出决定。What we should do with the problem is undecided. 我们所需要的是时间。What we need is time. 对她来说,最重要的是她的家庭。What is important to her is her family. 谁去都是一样的。、Who will go makes no difference. 哪一组赢得比赛还不知道。Which team will win the game is still unknown. 她去哪了还是个迷Where she has gone is a mystery. 这个怎么发生的还不清楚。How this happened is not clear. 他们什么时候开始还不知道。When they will start is still unkown yet. 无论你说什么都会让她生气。Whatever you say will made her angry. 无论是谁,第一个来就可以获得礼物。Whoever comes first can get a present. 2.形式主语: 1).that 引导的从句做主语时候,为了避免头重教轻,常用It 做形式上的主语而将That从句放句末。That(不充当成份,无意思)he got the first price excited him. = It excited him that he got the first price. 2).常见的形式主语结构 1.It + 系动词+形容词+ That从句: It is clear that the whole project is doomed to failure. It is likely that there will be a snowstorm tomorrow. 2.It + 系动词+名词+ That从句:(a pity,a shame, a fact, an honour, a wonder, no wonder,good news) It is a pity that you didn’t attend their wedding.

名词性从句 一、概念: 在句中起名词作用的句子称名词性从句。名词性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,名词性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。 1、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 2、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。例如: That she was chosen made us very happy. 她被选上了,我们很高兴。 We heard the news that our team had won. 我们听到消息说我们队赢了。 注: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:①whether引导主语从句并在句首②引导表语从句③whether 从句作介词宾语④从句后有"or not" 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。例如: It is not important who will go. 谁去,这不重要。 It is still unknown which team will win the match. 到底谁赢呢,形势尚不明朗。 3、名词性that-从句 ①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。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. 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。 ②That-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。 ①由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever 等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等。例如: 主语:How the book will sell depends on its author.书销售如何取决于作者本人。 直接宾语:In one's own home one can do what one likes.在自己家里可以随心所欲。 间接宾语:The club will give whoever wins a prize.获胜者俱乐部将颁奖。 表语:My question is who will take over president of the Foundation.我的问题是谁将接任该基金会主席职位。 宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。 同位语:I have no idea when he will return.我不知道他什么时候回来。 形容词宾语:I'm not sure why she refused their invitation.我尚不能肯定她为什么拒绝他们的邀请。 介词宾语:That depends on where we shall go. 那取决于我们去哪儿。 ②Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末。例如: It is not yet decided who will do that job.还没决定谁做这项工作。 It remains unknown when they are going to get married.他们何时结婚依然不明。 5、if, whether引导的名词从句 ①yes-no型疑问从句 从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同。例如: 主语:Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。 宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。 表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。 同位语:They are investigating the question whether the man is trustworthy.他们调查他是否值得信赖。 形容词宾语:She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。 介词宾语:I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。 ②选择性疑问从句 选择性疑问从句由关联词if/whether…or或whethe…or not构成。例如: Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。

英语三大从句

英语三大从句 说到英语,就不得不提到从句。从句是英语的重要的组成部分,而且,从句也有许多种类,比如定语从句,状语从句,名词性从句,强调句等等。但是,在学习英语时,很多学生都感到从句学习有些复杂。尤其是有些初学者,可能会因为一些知识点的混淆而混淆不清、难以理解。因此,在探究英语从句方面,更应该从三大从句类型开始,即定语从句、状语从句和名词性从句。 定语从句 定语从句是最常见的一类从句,也叫定语结构。定语从句的作用是修饰名词或代词,是构成句子的重要组成部分。它可以直接限定先行词,也可以通过联系词来限定先行词。定语从句的基本结构是连接词+主语+谓语。如果定语从句中含有宾语,则需要有宾语从句结构。定语从句中的连接词包括:that、which、who、whose、whom等。 状语从句 状语从句也叫状语结构,是描述主句中动作发生的时间、地点、原因、条件、结果等情况的句子,将状语从句放在句首或句尾时,可以使句子更加丰富、生动。状语从句常见的连接词包括:when(什么时候)、where(什么地方)、while(同时)、since(既然)、if(如果)、although(尽管)、because(因为)、unless(除非)等。 名词性从句 名词性从句又叫名词结构,是构成句子的重要组成部分,它可以作主语、宾语、表语或同位语。它的基本结构是主语+谓语,其中包

括实义句、祈使句、感叹句、特殊句式等。名词性从句中可用:that、whether、if、what等连接词引导。 以上就是关于英语三大从句的简要介绍,它们可以使我们更加全面地掌握英语句法和语法。在学习英语时,一定要深入理解它们的结构以及发音,分辨每种从句的特点及用法,以此来实现对英语的更好掌握。 在掌握英语句法结构的基础上,学生也要练习熟练地把这些知识运用到实际的写作中。首先,学生要把握句子的语法和语义,以此实现清晰、准确及丰富的表达。此外,学生还要把握一定的词汇,掌握正确的单词用法,以及使用正确的句型引导从句,这些都是合理构成句子和篇章的关键。 最后,学习从句的前提条件是学习英语的基础知识,即英语单词、句子和语法,而从句是英语的重要组成部分,学习者一定要把它们的结构及用法掌握得当,才可以更加深刻理解英语的结构和意义,以达到英语句法的规范掌握。

从属连词可分为三大类

•从属连词可分为三大类: 1、that (无词义,不做成分) if,whether (表达是否的意义,但不做句子成分) 2、连接代词:who,whom,whose,what,which,whatever, whoever, whichever (有词义,在句子中可作主语、表语、宾语) 3、连接副词:when,where,why,how,how many,how long,how far,however, whenever,wherever (有词义,作从句的状语) 用法: 从结构上说,英语连接词分两大类:并列连词和从属连词。 并列连词连接两个或两个以上地位平等的字、词组或分句。例如: (1) Air and water are indispensable to me. (2) She likes going out with friends or playing outdoor games. (3) Most workers have a good income, so they look very happy. 从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如: (4) He said that he did not want to go . (5) Many things have happened since I last saw him. (6) You may come if you want to. 从属连词用来连接各种从句。 until(till)直到,在用until表达时间状语的句子中,主句中的动词是要十分小心去选择的。 如动词是持续行动词,它要用肯定句,如: I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词,则要用否定句,如: He didn't go to bed until his mother came back. 由since,for,by,before, 来引导的时间状语从句。 since 引导的时间状语是动作的开始时间,如: I have studied English since 1990. 而by引导的时间状语通常是动作的结束时间,如: I had learned 25 English songs by the end of last term.
