【要点梳理】
近三年以来,重庆春考对于并列连词和从属连词的考察都有所侧重,其中转折连词是考察重点。
知识点一 连词的定义
连词是一种虚词,在句子中不能独立用作句子成分,它的作用是把词与词、短语与短语、句子与句子连接起来。一般都不重读。
知识点二 连词的分类
连词按其性质可分为并列连词和从属连词。
1. 并列连词
用于连接并列的单词、短语、从句或句子的词,可表示多种意义,如并列、转折、选择、因果等。
2. 从属连词
用于引出名词性从句(主语从句、宾语从句、表语从句、同位语从句)和状语从句(时间状语从句、条件状语从句、目的状语从句等)的词。
知识点三 连词的用法
1. 并列连词
(1)表示并列、选择关系的并列连词主要有and、 both...and...、 or、 otherwise、 either...or...、 neither...nor...、 not only...but (also)...等。
①and、 both...and...和or。
a. and意为“和”,用于肯定句;否定句和疑问句中通常用or
b. both...and...表示“两者都”,若连接两个主语,谓语动词只能用复数形式。
如: In the party tonight, Mary will both sing and dance.
在今晚的晚会上,玛丽既要唱歌又要跳舞。
Both she and I are good at English. 她和我都擅长英语。
注 如果连接的两个主语表示的是同一事物,谓语动词用单数形式。
如: Bread and butter is my favourite. 面包配黄油是我的最爱
c. or意为“或,或者;还是;否则”,表示一种选择关系。or连接主语时,谓语动词与or后面的主语保持一致。
如: She likes maths and English. 她喜欢数学和英语。
She doesn't like maths or English. 她不喜欢数学和英语。
但含有两个否定词的句子实际被看作是肯定结构,因此要用and。
There is no food and no drink here. 这里没有食物和饮料。
如: You can go there by bus or on foot. 你可以坐公共汽车或步行去那里。
Are you a doctor or a teacher? 你是医生还是老师?
Hurry up, or you'll be late. 快点,否则你会迟到的。
=If you don't hurry up, you'll be late. 如果你不快点,你会迟到的。
②otherwise意为“否则,不然”。
如: We'll go early, otherwise we may not get a good seat.
我们得早点去,要不然就没有好座位了。
We didn't know you were in trouble at that time, otherwise we would have given you a hand. 我们当时不知道你遇到了困难,要不然我们会帮助你的。
③either...or...意为“要么……要么……,或者……或者……,不是……就是……”,用于连接两个性质相同的词或短语,有时也可以连接两个句子。
如: You either come in or go out. Don't just stand there.
你要么进来要么出去。别站在那里。
注 either...or...连接两个成分作主语时,谓语动词通常与其靠近的主语保持一致。
如: Either you or I am to go there. 你去或我去那里。
Either you or she is going to Shanghai. 要么你去上海,要么她去。
④neither...nor...意为“既不……也不……”,其含义是否定的,可连接任意两个并列的成分。
如: She likes neither coffee nor tea. She just likes water.她既不喜欢咖啡也不喜欢茶。只喜欢水。
The weather is pretty good today; it is neither too hot nor too cold.
今天天气很好,既不太冷也不太热。
⑤not only...but (also)...意为“不仅……而且……”。
如: My grandpa can speak not only English but also Russian.
我爷爷不仅会说英语还会说俄语。
I can not only sing but also dance. 我不但会唱歌而且会跳舞。
Not only she but also I am good at speaking English. 不仅她擅长说英语,我也擅长。
(2)表示转折、对比关系的并列连词有but、 however、 yet、 still、 while等。
①but与however: 两者都意为“但是,然而”。but 表示的是非常明显的对比,转折意义比however强,一般不用逗号隔开;而however通常要用逗号与句子其他成分隔开。
②yet意为“然而”。
如: He studied hard yet he failed many times. 他学习努力,可是失败很多次。
③still意为“尽管如此,可还是要;然而;不过”。
如: Although we are very tired, still we shall work. 虽然我们很累,但我们还是要工作。
④while 连接两个并列句子,表示对比关系,意为“然而”。
(3)表示因果关系的并列连词有for、 so等。
①for意为“因为,由于”,补充说明理由,不用于句首。
如: John is absent from school today, for he is uncomfortable. 约翰今天没来上课,因为他不舒服了。
②so意为“因此,所以”。
2. 从属连词
(1)引导时间状语从句的从属连词。
①意为“当……时候”或“每当”的时间连词主要有 when、 while、 as、 whenever。
②意为“在……之前(之后)”的时间连词主要有before、 after。
③since、 until、 till 意为“自从”或“直到”。since 主要用于有完成时态的句子中,主句通常用现在完成时态,since引导的从句通常用过去时态。
④as soon as 意为“一……就……”; the moment、 the minute、 immediately、 directly、 once 等,意为“立刻,马上”,也可表示“一……就……”。
(2)引导条件状语从句的从属连词主要有if(如果)、 unless(除非)、 in case(万一,以防)等。
(3)引导目的状语从句的从属连词主要有 in order that/so that(以便,为了)。
(4)引导结果状语从句的从属连词主要有so that(因此,所以)、 so...that...、 such...that...等。
(5)引导原因状语从句的从属连词主要有because、 since、 as等,其语气由强到弱。
如: He distrusted me because I was new here. 他不信任我,因为我是新来的。
We all like her as she is kind and helpful. 我们都喜欢她,因为她善良。
(6)although/though 意为“虽然”,even though/even if意为“即使;尽管”,引导让步状语从句。
注 ①although=though, even though=even if,都不能和but连用。
注 ②however、 whatever、 whoever、 whenever、 wherever=no matter how/what/who/when/where,意为“无论怎样/什么/谁/何时/何地”。
(7)as(像,按照,如同)、 as if/as though(好像)引导方式状语从句。
(8)引导名词性从句的从属连词主要有that、 whether/if(是否)等,它们用于引导主语从句、表语从句、宾语从句和同位语从句。其中that不充当句子成分,而且没有词义,在句子中只起连接作用;而 if、 whether 虽不充当句子成分,但有词义,意为“是否”。

表示动作或行为状态的词叫作动词,它是构成句子的核心,是英语句子中不可缺少的重要组成部分。动词有时态、语态和语气的变化。
知识点二 动词的分类
动词可以分为行为动词、连系动词、助动词和情态动词四类。另外,动词有五种基本形式:以动词do为例,原形为do,第三人称单数形式为does,过去式为did,过去分词为done,现在分词为doing。这五种形式和助动词一起构成动词的各种时态、语态和语气。
知识点三 动词的用法
1. 连系动词
连系动词是用来辅助说明主语的词,本身有词义,但是不能单独作谓语,必须与表语构成系表结构来说明主语的状况、性质、特征等,表语通常为形容词。
连系动词的分类:
(1)表示主语状态和特征的词:be动词。
如: He is a famous doctor. 他是一位名医。

第07讲:单项选择之连词动词部分重点难点
知识梳理
演练
【考情链接】
【要点梳理】
近三年以来,重庆春考对于并列连词和从属连词的考察都有所侧重,其中转折连词是考察重点。
知识点一 连词的定义
连词是一种虚词,在句子中不能独立用作句子成分,它的作用是把词与词、短语与短语、句子与句子连接起来。一般都不重读。
知识点二 连词的分类
连词按其性质可分为并列连词和从属连词。
1. 并列连词
用于连接并列的单词、短语、从句或句子的词,可表示多种意义,如并列、转折、选择、因果等。
2. 从属连词
用于引出名词性从句(主语从句、宾语从句、表语从句、同位语从句)和状语从句(时间状语从句、条件状语从句、目的状语从句等)的词。
知识点三 连词的用法
1. 并列连词
(1)表示并列、选择关系的并列连词主要有and、 both...and...、 or、 otherwise、 either...or...、 neither...nor...、 not only...but (also)...等。
①and、 both...and...和or。
a. and意为“和”,用于肯定句;否定句和疑问句中通常用or
b. both...and...表示“两者都”,若连接两个主语,谓语动词只能用复数形式。
如: In the party tonight, Mary will both sing and dance.
在今晚的晚会上,玛丽既要唱歌又要跳舞。
Both she and I are good at English. 她和我都擅长英语。
注 如果连接的两个主语表示的是同一事物,谓语动词用单数形式。
如: Bread and butter is my favourite. 面包配黄油是我的最爱
c. or意为“或,或者;还是;否则”,表示一种选择关系。or连接主语时,谓语动词与or后面的主语保持一致。
如: She likes maths and English. 她喜欢数学和英语。
She doesn't like maths or English. 她不喜欢数学和英语。
但含有两个否定词的句子实际被看作是肯定结构,因此要用and。
There is no food and no drink here. 这里没有食物和饮料。
如: You can go there by bus or on foot. 你可以坐公共汽车或步行去那里。
Are you a doctor or a teacher? 你是医生还是老师?
Hurry up, or you'll be late. 快点,否则你会迟到的。
=If you don't hurry up, you'll be late. 如果你不快点,你会迟到的。
②otherwise意为“否则,不然”。
如: We'll go early, otherwise we may not get a good seat.
我们得早点去,要不然就没有好座位了。
We didn't know you were in trouble at that time, otherwise we would have given you a hand. 我们当时不知道你遇到了困难,要不然我们会帮助你的。
③either...or...意为“要么……要么……,或者……或者……,不是……就是……”,用于连接两个性质相同的词或短语,有时也可以连接两个句子。
如: You either come in or go out. Don't just stand there.
你要么进来要么出去。别站在那里。
注 either...or...连接两个成分作主语时,谓语动词通常与其靠近的主语保持一致。
如: Either you or I am to go there. 你去或我去那里。
Either you or she is going to Shanghai. 要么你去上海,要么她去。
④neither...nor...意为“既不……也不……”,其含义是否定的,可连接任意两个并列的成分。
如: She likes neither coffee nor tea. She just likes water.她既不喜欢咖啡也不喜欢茶。只喜欢水。
The weather is pretty good today; it is neither too hot nor too cold.
今天天气很好,既不太冷也不太热。
⑤not only...but (also)...意为“不仅……而且……”。
如: My grandpa can speak not only English but also Russian.
我爷爷不仅会说英语还会说俄语。
I can not only sing but also dance. 我不但会唱歌而且会跳舞。
Not only she but also I am good at speaking English. 不仅她擅长说英语,我也擅长。
(2)表示转折、对比关系的并列连词有but、 however、 yet、 still、 while等。
①but与however: 两者都意为“但是,然而”。but 表示的是非常明显的对比,转折意义比however强,一般不用逗号隔开;而however通常要用逗号与句子其他成分隔开。
②yet意为“然而”。
如: He studied hard yet he failed many times. 他学习努力,可是失败很多次。
③still意为“尽管如此,可还是要;然而;不过”。
如: Although we are very tired, still we shall work. 虽然我们很累,但我们还是要工作。
④while 连接两个并列句子,表示对比关系,意为“然而”。
(3)表示因果关系的并列连词有for、 so等。
①for意为“因为,由于”,补充说明理由,不用于句首。
如: John is absent from school today, for he is uncomfortable. 约翰今天没来上课,因为他不舒服了。
②so意为“因此,所以”。
2. 从属连词
(1)引导时间状语从句的从属连词。
①意为“当……时候”或“每当”的时间连词主要有 when、 while、 as、 whenever。
②意为“在……之前(之后)”的时间连词主要有before、 after。
③since、 until、 till 意为“自从”或“直到”。since 主要用于有完成时态的句子中,主句通常用现在完成时态,since引导的从句通常用过去时态。
④as soon as 意为“一……就……”; the moment、 the minute、 immediately、 directly、 once 等,意为“立刻,马上”,也可表示“一……就……”。
(2)引导条件状语从句的从属连词主要有if(如果)、 unless(除非)、 in case(万一,以防)等。
(3)引导目的状语从句的从属连词主要有 in order that/so that(以便,为了)。
(4)引导结果状语从句的从属连词主要有so that(因此,所以)、 so...that...、 such...that...等。
(5)引导原因状语从句的从属连词主要有because、 since、 as等,其语气由强到弱。
如: He distrusted me because I was new here. 他不信任我,因为我是新来的。
We all like her as she is kind and helpful. 我们都喜欢她,因为她善良。
(6)although/though 意为“虽然”,even though/even if意为“即使;尽管”,引导让步状语从句。
注 ①although=though, even though=even if,都不能和but连用。
注 ②however、 whatever、 whoever、 whenever、 wherever=no matter how/what/who/when/where,意为“无论怎样/什么/谁/何时/何地”。
(7)as(像,按照,如同)、 as if/as though(好像)引导方式状语从句。
(8)引导名词性从句的从属连词主要有that、 whether/if(是否)等,它们用于引导主语从句、表语从句、宾语从句和同位语从句。其中that不充当句子成分,而且没有词义,在句子中只起连接作用;而 if、 whether 虽不充当句子成分,但有词义,意为“是否”。

知识点一 动词的定义
表示动作或行为状态的词叫作动词,它是构成句子的核心,是英语句子中不可缺少的重要组成部分。动词有时态、语态和语气的变化。
知识点二 动词的分类
动词可以分为行为动词、连系动词、助动词和情态动词四类。另外,动词有五种基本形式:以动词do为例,原形为do,第三人称单数形式为does,过去式为did,过去分词为done,现在分词为doing。这五种形式和助动词一起构成动词的各种时态、语态和语气。
知识点三 动词的用法
1. 连系动词
连系动词是用来辅助说明主语的词,本身有词义,但是不能单独作谓语,必须与表语构成系表结构来说明主语的状况、性质、特征等,表语通常为形容词。
连系动词的分类:
(1)表示主语状态和特征的词:be动词。
如: He is a famous doctor. 他是一位名医。
The doctors are very busy now. 医生们现在正忙。
(2)表示主语状态变化的词: become、 grow、 turn、 fall、 get、 go、 come等。
如: When autumn comes, the leaves from the trees turn yellow. 秋天来了,树叶黄了。
It is getting colder and colder. 天气变得越来越热了。
(3)表示某种状态延续或持续的词: keep、 remain、 stay 等。
(4)感官动词: look、 feel、 smell、 sound、 taste、 touch、 appear、 seem等作连系动词时,通常用形容词作表语。
This rose smells very sweet. 这朵玫瑰闻起来很香。
模拟练习2
( D )1. The rice in the bowl ________.
A. smells well B. is smelt well
C. is smelt good D. smells good
【解析】句意: 本题考查“连系动词+形容词”结构。 good是形容词, well是副词,连系动词通常不用于被动语态。
( C )2. Most of the leaves ________ yellow when autumn comes along.
A. keep B. look C. turn D. get
【解析】句意:本题考查“连系动词+形容词”结构。
( B )3. The white T-shirt ________ soft and ________ well.
A. is felt; sell B. feels; sells
C. is felt; sold D. feel; sells
【解析】句意: feel意为“摸起来”,作连系动词,后接形容词作表语;sell是实义动词,well是副词,用副词修饰实义动词。
( D )4. The new piece of music ________ beautiful.
A. is sounding B. listens
C. is hearing D. sounds
【解析】句意: “听起来很优美”可用sound beautiful表示。
( A )5. She ________ so sad. What's wrong with her?
A. looks B. watches C. reads D. look
【解析】句意: look作为连系动词表示“看起来”,主语是第三人称单数,所以用looks。 watch用于“观看比赛、戏剧等”,read用于“看书看报”。
2. 行为动词
行为动词又称为实义动词,它有实在的意义,在句子中可独立作谓语。
(1)行为动词的分类。
行为动词分为及物动词和不及物动词。及物动词后可以直接接宾语;不及物动词后不能直接接宾语,如果要接宾语必须加上适当的介词。
如:Jack plays(及物动词) basketball(宾语) every day. 杰克每天打篮球。
My mother is looking(不及物动词) after(介词) my sick younger sister(宾语).
妈妈正在照顾我的生病的妹妹。

4. 情态动词
情态动词本身有一定的词义,但是不能独立作谓语,只能放在行为动词连系动词前,一起构成谓语。情态动词用在行为动词前,表示说话人对这一动作或状态的看法或建议命令等。情态动词一般无人称和数的变化(have to除外)。从本质上说,情态动词相当于一种助动词,它可以构成否定句、疑问句等。
