【备考2019】英语3年中考2年模拟一轮专题复习学案第八讲 连词 原卷

中考英语对连词考查的频率很高,对连词的考查主要侧重并列连词、从属连词的用法、相似连词的辨析。考生在复习时应注意熟记表示转折对比关系的并列连词、表示因果关系的并列连词、表示选择关系的并列连词、表示并列关系的并列连词,以及常用连词的用法辨析。对于连词的考察,通常出现在单项选择、完形填空中以及书面表达中。

一、连词的功能及分类
思维导图记知识点
1.连词的功能
用来连接词,短语,从句或句子的词叫连词。连词是一种虚词,在句中不能单独使用。连词可分为两类:并列连词和从属连词。
2.并列连词
并列连词用来连接具有并列关系的词,短语或句子。常见的并列连词有:
(1)表并列关系的and, both…and, not only…but also, neither…nor等。
(2)表选择关系的or, either…or等。
(3)表转折关系的but, while等。
(4)表因果关系的for, so等。
3.从属连词
从属连词用来引导从句。常见的从属连词有:
引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。
(2)引导条件状语从句的if, unless等。
(3)引导原因状语从句的because, as, since等。
(4)引导目的状语从句的so that, in order that等。
(5)引导让步状语从句的though, although, even if等。
(6)引导结果状语从句的so that, so…that, such…that等。
(7)引导比较状语从句的than, as…as等。
(8)引导名词从句的that, if , whether等。
二、常用连词的用法辨析
(1) while, when, as这三个连词都可引导时间状语从句,但用法有所不同。
1) 当某事正在进行的时候,又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。例如:
As/When/While I was walking down the street I noticed a police car.我沿着街道走时,注意到一辆警车。
2) 当两个长动作同时进行的时候,最常用的是while。例如:
While mother was cooking lunch, I was doing my homework.当母亲做午饭时,我正在做作业。
3) 当两个动作都表示发展变化的情况时,最常用的是as。例如:
As children get older, they become more and more interested in things around them.随着孩子的长大,他们越来越多对周围的事情感兴趣。
4) 当两个短动作同时发生时,或表示“一边…一边…”时,最常用as。例如:
She looked behind from time to time as she went.她边走边不时地朝后面看。
5) 当从句的动作先于主句的动作时,通常用when。例如:
When he finished his work, he took a short rest.当他完成工作后,他进行了短暂的休息。
6) 当从句是瞬间动作,主句是延续性动作时,通常用when。例如:
When John arrived I was cooking lunch.当约翰到达时,我正在做饭。
(2)as, because, since , for这四个词都可表原因,但用法有区别。
1) 如果原因构成句子的最主要部分,一般用because。因此,because引导的从句往往放在句末。例如:
I stayed at home because it rained.因为下雨,所以我呆在家里。
---Why aren’t you going? 为什么你不走?---Because I don’t want to.因为我不想去。
2) 如果原因已被人们所知,或不如句子的其它部分重要,就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如:
As he wasn’t ready, we left without him.由于他没有准备,我们没有带他。
Since I have no money, I can’t buy any food.既然我没有钱,我不能卖任何食物。
3) for用来补充说明一种理由,因此,for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。例如:
I decided to stop and have lunch----for I was feeling quite hungry.我决定停下来,吃午饭。因我感觉很饿。
(3)if, whether
if和whether都可作“是否”讲,在引导宾与从句是一般可互换。例如:
I wonder whether (if) you still study in that school.我想知道你是否还在那所学校学习。
I don’t know whether (if) he likes that film.我不知道他是否喜欢这部电影。
在下列情况下,只能用whether,不能用if:
1) 引导主语从句时。例如:
Whether he will come to the party is unknown. 他是否来参加聚会还不知道。
2) 引导表语从句时。例如:
The question is whether I can pass the exam.问题是我能否通过考试。
3) 在不定式前。例如:
I haven’t made up my mind whether to go there or not.我还没有决定是否去哪儿。
(4)so…that, such...that
1) so…that中的so是个副词,其后只能跟形容词或副词,而such...that中的such是个形容词,后接名词或名词短语。例如:
I’m so tired that I can’t walk any farther.我很累,因此不想再走了。
It was such a hot day that he went swimming.如此热的天气,以至于他去游泳。
2) 如果在名词之前有many, much, little, few时,用so,不用such。例如:
He has so little education that he is unable to get a job.他受到得教育很少以致于他找不到工作。
(5)either…or…, neither…nor, not only…but also…
这三个连词词组都可连接两个并列成分。当它们连接两个并列主语时,谓语动词要随相邻的主语变化。例如:
Either you or he is wrong.
Neither he nor his children like fish.不但他不喜欢而且他的孩子也不喜欢鱼。
Not only the teacher but also the students want to buy the book.不但老师而且学生想买这本书。
(6)although, but
这两个连词不能用在同一个句子中。例如:我们不能说“Although he is over sixty, but he works as hard as others.”这个句子应改为:Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others.尽管他已是六十多岁,但他和其他工作一样努力。
(7)because, so
这两个连词同样不能用在同一个句子中。例如:我们不能说“Because John
was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor. 因为约翰病了,所以我带他看医生。
三、并列句的分类:
1. 表示同等关系的并列句
这类并列句常用并列连词and连接前后简单句,and常译为“和”、“并且”,也可不译出来。例如:
He likes playing football and he plays well.他喜欢踢足球,并且踢得很好。?
2. 表示转折关系的并列句
这类并列句常用并列连词but(但是),yet(可是),while(而,另一方面),however(可是)等连接前后简单句,but常译为“但是”,“可是”,切不可与从属连词though或although一起使用。例如:
It has no mouth, but it can talk. 它没有嘴巴,但是它会说话。?
3. 表示选择关系的并列句
这类并列句常用并列连词or(或者,否则)等连接前后简单句。
or有两重含义:?
(1)译为“或者”,表示选择。例如:
Now you can have a rest or you can go to the cinema.现在你可以休息,或者去看电影。
(2)译为“否则”、“要不然”,表示条件。例如:
You must tell the truth,or you will be punished.你必须说真话,否则你将会受到惩罚。?
4. 表示因果关系的并列句
这类并列句常用并列连词for,so等连接前后简单句。
(1)for在意义上与从属连词because,since和as相同,但它们引导的是原因状语从句,而for则连接两
简单句,前者表示结果,后者表示原因。其结构为:简单句(结果)+for+简单句(原因)。
例如:He has many good friends, for he is an honest man。他有许多好朋友,因为他是个诚实的男子汉。
(2)so意为“因此”、“所以”,但不能与because同时出现在同一个句子中。因为because是从属连词,而是并列连词,用来连接并列句。其结构为:简单句(原因)? +so牛简单句(结果)。例如:
Mr. Li went to his hometown, so Mr. Wang was taking his class instead.李老师回家乡去了,所以王老师替二课。
5. 其他形式的并列句
(1)“祈使句+and+简单句”。其中祈使句表示一个条件,并列连词and引导的简单句则表示一个较好的结果,谓语常用一般将来时。例如:
Use your head, and you will find away.动脑筋,你就会想出办法来。
(2)“祈使句+or+简单句”。祈使句表示一个条件,并列连词or后的简单句则表示一个不愉快或不理想的结果。例如:
Study hard, or you Will fall behind the others.努力学习,否则你就会落于别人。
(3)“either...or”结构表示“不是……就是……”,“或者……或者……”,例如:
Either my uncle can do it, or my aunt can do it. 我叔叔可以做那件事,或者我婶婶也可以做。
习惯上将两个句子合并成Either my uncle or my aunt can do it.
(4) “not only…but also”意思为“不仅……而且……”,例如:
not only the students have missed the school car, but also the teacher has missed the school car.不仅学生,而且他们的老师都误了校车。
(5) “neither…nor…”结构,意为“既不……也不……”,“两者都不……”,用法与either …or…,not only …but also…相同。
五、使用并列句要注意的几种情况
1. 并列句有时可不用连词,而用分号隔开(前后句之间的关系须相当紧密)。例如:
We fished all day; we didn't catch a fish.我们钓了一天的鱼,一条鱼也没钓到。
2. 并列连词后的简单句如果与其前的简单句有相同的部分,则相同的部分常可省略。例如:
My father works in a factory and my mother in a school.我父亲在工厂工作,母亲在学校工作。
3. 由so, nor, neither连接的并列句,后一简单句为避免重复,其成份常倒装并省略一些。例如:
He is not a student, nor am I. 他不是学生,我也不是。
Beibei can swim, so can I. 贝贝会游泳, 我也会。

考点一:考查表示转折对比关系的并列连词
典例1:(2018南京)2.Mexican and Tex-Mex foods were popular in the USA, ____now Chinese food has more fans.
A.because B.but C.so D.unless

举一反三

【答案】B
举一反三

【答案】D
【解析】句意:——你为什么不习惯北京的生活?——既不是因为拥挤的交通,也不是因为高昂的生活费用。唯一的原因是污染严重的空气。考查连词辨析。Not only…but also…不但……而且……;Either…or…要么……要么;Both…and…(……和……)都;Neither…nor…既不……也不……。根据句意判断:—你为什么不习惯北京的生活?—既非交通拥挤也非生活消费高。唯一原因就是严重污染的空气。故选D。

A.Both,and B.Not only,but also C.Neither,nor

【备考2019】英语3年中考2年模拟一轮专题复习学案第八讲 连词 解析卷

中考英语对连词考查的频率很高,对连词的考查主要侧重并列连词、从属连词的用法、相似连词的辨析。考生在复习时应注意熟记表示转折对比关系的并列连词、表示因果关系的并列连词、表示选择关系的并列连词、表示并列关系的并列连词,以及常用连词的用法辨析。对于连词的考察,通常出现在单项选择、完形填空中以及书面表达中。

一、连词的功能及分类
思维导图记知识点
1.连词的功能
用来连接词,短语,从句或句子的词叫连词。连词是一种虚词,在句中不能单独使用。连词可分为两类:并列连词和从属连词。
2.并列连词
并列连词用来连接具有并列关系的词,短语或句子。常见的并列连词有:
(1)表并列关系的and, both…and, not only…but also, neither…nor等。
(2)表选择关系的or, either…or等。
(3)表转折关系的but, while等。
(4)表因果关系的for, so等。
3.从属连词
从属连词用来引导从句。常见的从属连词有:
引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。
(2)引导条件状语从句的if, unless等。
(3)引导原因状语从句的because, as, since等。
(4)引导目的状语从句的so that, in order that等。
(5)引导让步状语从句的though, although, even if等。
(6)引导结果状语从句的so that, so…that, such…that等。
(7)引导比较状语从句的than, as…as等。
(8)引导名词从句的that, if , whether等。
二、常用连词的用法辨析
(1) while, when, as这三个连词都可引导时间状语从句,但用法有所不同。
1) 当某事正在进行的时候,又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。例如:
As/When/While I was walking down the street I noticed a police car.我沿着街道走时,注意到一辆警车。
2) 当两个长动作同时进行的时候,最常用的是while。例如:
While mother was cooking lunch, I was doing my homework.当母亲做午饭时,我正在做作业。
3) 当两个动作都表示发展变化的情况时,最常用的是as。例如:
As children get older, they become more and more interested in things around them.随着孩子的长大,他们越来越多对周围的事情感兴趣。
4) 当两个短动作同时发生时,或表示“一边…一边…”时,最常用as。例如:
She looked behind from time to time as she went.她边走边不时地朝后面看。
5) 当从句的动作先于主句的动作时,通常用when。例如:
When he finished his work, he took a short rest.当他完成工作后,他进行了短暂的休息。
6) 当从句是瞬间动作,主句是延续性动作时,通常用when。例如:
When John arrived I was cooking lunch.当约翰到达时,我正在做饭。
(2)as, because, since , for这四个词都可表原因,但用法有区别。
1) 如果原因构成句子的最主要部分,一般用because。因此,because引导的从句往往放在句末。例如:
I stayed at home because it rained.因为下雨,所以我呆在家里。
---Why aren’t you going? 为什么你不走?---Because I don’t want to.因为我不想去。
2) 如果原因已被人们所知,或不如句子的其它部分重要,就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如:
As he wasn’t ready, we left without him.由于他没有准备,我们没有带他。
Since I have no money, I can’t buy any food.既然我没有钱,我不能卖任何食物。
3) for用来补充说明一种理由,因此,for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。例如:
I decided to stop and have lunch----for I was feeling quite hungry.我决定停下来,吃午饭。因我感觉很饿。
(3)if, whether
if和whether都可作“是否”讲,在引导宾与从句是一般可互换。例如:
I wonder whether (if) you still study in that school.我想知道你是否还在那所学校学习。
I don’t know whether (if) he likes that film.我不知道他是否喜欢这部电影。
在下列情况下,只能用whether,不能用if:
1) 引导主语从句时。例如:
Whether he will come to the party is unknown. 他是否来参加聚会还不知道。
2) 引导表语从句时。例如:
The question is whether I can pass the exam.问题是我能否通过考试。
3) 在不定式前。例如:
I haven’t made up my mind whether to go there or not.我还没有决定是否去哪儿。
(4)so…that, such...that
1) so…that中的so是个副词,其后只能跟形容词或副词,而such...that中的such是个形容词,后接名词或名词短语。例如:
I’m so tired that I can’t walk any farther.我很累,因此不想再走了。
It was such a hot day that he went swimming.如此热的天气,以至于他去游泳。
2) 如果在名词之前有many, much, little, few时,用so,不用such。例如:
He has so little education that he is unable to get a job.他受到得教育很少以致于他找不到工作。
(5)either…or…, neither…nor, not only…but also…
这三个连词词组都可连接两个并列成分。当它们连接两个并列主语时,谓语动词要随相邻的主语变化。例如:
Either you or he is wrong.
Neither he nor his children like fish.不但他不喜欢而且他的孩子也不喜欢鱼。
Not only the teacher but also the students want to buy the book.不但老师而且学生想买这本书。
(6)although, but
这两个连词不能用在同一个句子中。例如:我们不能说“Although he is over sixty, but he works as hard as others.”这个句子应改为:Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others.尽管他已是六十多岁,但他和其他工作一样努力。
(7)because, so
这两个连词同样不能用在同一个句子中。例如:我们不能说“Because John
was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor. 因为约翰病了,所以我带他看医生。
三、并列句的分类:
1. 表示同等关系的并列句
这类并列句常用并列连词and连接前后简单句,and常译为“和”、“并且”,也可不译出来。例如:
He likes playing football and he plays well.他喜欢踢足球,并且踢得很好。?
2. 表示转折关系的并列句
这类并列句常用并列连词but(但是),yet(可是),while(而,另一方面),however(可是)等连接前后简单句,but常译为“但是”,“可是”,切不可与从属连词though或although一起使用。例如:
It has no mouth, but it can talk. 它没有嘴巴,但是它会说话。?
3. 表示选择关系的并列句
这类并列句常用并列连词or(或者,否则)等连接前后简单句。
or有两重含义:?
(1)译为“或者”,表示选择。例如:
Now you can have a rest or you can go to the cinema.现在你可以休息,或者去看电影。
(2)译为“否则”、“要不然”,表示条件。例如:
You must tell the truth,or you will be punished.你必须说真话,否则你将会受到惩罚。?
4. 表示因果关系的并列句
这类并列句常用并列连词for,so等连接前后简单句。
(1)for在意义上与从属连词because,since和as相同,但它们引导的是原因状语从句,而for则连接两
简单句,前者表示结果,后者表示原因。其结构为:简单句(结果)+for+简单句(原因)。
例如:He has many good friends, for he is an honest man。他有许多好朋友,因为他是个诚实的男子汉。
(2)so意为“因此”、“所以”,但不能与because同时出现在同一个句子中。因为because是从属连词,而是并列连词,用来连接并列句。其结构为:简单句(原因)? +so牛简单句(结果)。例如:
Mr. Li went to his hometown, so Mr. Wang was taking his class instead.李老师回家乡去了,所以王老师替二课。
5. 其他形式的并列句
(1)“祈使句+and+简单句”。其中祈使句表示一个条件,并列连词and引导的简单句则表示一个较好的结果,谓语常用一般将来时。例如:
Use your head, and you will find away.动脑筋,你就会想出办法来。
(2)“祈使句+or+简单句”。祈使句表示一个条件,并列连词or后的简单句则表示一个不愉快或不理想的结果。例如:
Study hard, or you Will fall behind the others.努力学习,否则你就会落于别人。
(3)“either...or”结构表示“不是……就是……”,“或者……或者……”,例如:
Either my uncle can do it, or my aunt can do it. 我叔叔可以做那件事,或者我婶婶也可以做。
习惯上将两个句子合并成Either my uncle or my aunt can do it.
(4) “not only…but also”意思为“不仅……而且……”,例如:
not only the students have missed the school car, but also the teacher has missed the school car.不仅学生,而且他们的老师都误了校车。
(5) “neither…nor…”结构,意为“既不……也不……”,“两者都不……”,用法与either …or…,not only …but also…相同。
五、使用并列句要注意的几种情况
1. 并列句有时可不用连词,而用分号隔开(前后句之间的关系须相当紧密)。例如:
We fished all day; we didn't catch a fish.我们钓了一天的鱼,一条鱼也没钓到。
2. 并列连词后的简单句如果与其前的简单句有相同的部分,则相同的部分常可省略。例如:
My father works in a factory and my mother in a school.我父亲在工厂工作,母亲在学校工作。
3. 由so, nor, neither连接的并列句,后一简单句为避免重复,其成份常倒装并省略一些。例如:
He is not a student, nor am I. 他不是学生,我也不是。
Beibei can swim, so can I. 贝贝会游泳, 我也会。
