主谓一致对于这一语法的掌握大部分靠理解后的记忆。
关键要找准主语,再看其句式结构,按照规则办事。
另外,对于作主语的名词还要分清是可数名词还是不可数名词。
谓语受主语支配,须和主语在人称和数上保持一致,叫主谓一致。
处理主谓一致问题可依据三项原则:语法上一致、意义上一致和就近一致。
一、语法上一致:谓语和主语通常是从语法形式上取得一致,即主语为单数形式,谓语动词也采用单数形式,主语为复数,谓语也为复数形式。
A、谓语用单数的情况1、动词不定式、动名词短语或从句作主语时。
例:The boy is clever enough to study maths well.To work hard is necessary.Reading aloud is very important in learning a foreign language.Whether she comes or not is of no matter.2、主语是each/every+单数名词+and(each/every)+单数名词时,谓语动词用单数。
例如:Each boy and each girl has got a seat. 每个男孩和女孩都有一个座位。
Every man and every woman is at work. 每个男人和女人都在工作。
3、more than one+单数名词作主语,谓语用单数。
例如:More than one student has ever been to Beijing. 不止一个学生曾经去过北京。
4、某些不定代词,如either, neither, each, one, the other, another, anybody, anyone, anything,somebody, someone, something, every body, every one, everything, nobody, no one, nothing.等,当它们作主语时,通常用单数。
主谓一致主谓一致指的是句子的主语和谓语在人称和数上要保持一致,通常有以下三种原则:语法一致原则主语和谓语通常是在语法形式上取得一致,即主语是单数形式,谓语动词用单数形式;主语是复数形式,谓语动词用复数形式。
1. 单数主语搭配单数谓语:如果主语是可数名词单数、不可数名词或者第三人称单数代词(如he、she、it 等),谓语动词要用相应的单数形式。
The dog runs fast. 主语“dog” 是可数名词单数,谓语动词“runs” 采用了第三人称单数形式。
Water is essential for life. water为不可数名词,谓语动词“is” 是单数形式。
2. 复数主语搭配复数谓语:当主语是可数名词复数时,谓语动词需使用复数形式。
The trees are green in spring. trees为可数名词复数,谓语动词“are” 是复数形式。
3.当and 或both...and..连接两个或两个以上名词作主语时,谓语动词用复数形式。
Tom and Mike are good friends.汤姆和迈克是好朋友。
Both Lucy and Lily are students.露西和莉莉都是学生。
4. 不定代词either, neither, each one, the other, another, anybody , anyone , anything , someone , somebody , something, everyone,everybody ,everything , nobody , no one , nothing等作主语时,谓语动词用单数形式。
Everyone is ready for the sports meeting.大家都在为运动会做准备。
5. 由each , each...and each..., every ...and every...作主语时,谓语动词用单数形式。
英语语法主谓一致知识点总结主谓一致,指的是句子的主语和谓语在人称和数上的一致,这一点,英语和汉语不同,学生一定要弄清楚了。
小编为大家力荐了主谓一致语法归纳,给大家作为参考,欢迎阅读!主谓一致的用法一、并列结构作主语谓语用复数Reading and writing are very important.注意:当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and 此时连接的两个词前只有一个冠词。
The iron and steel industry is very important to our life.典型例题The League secretary and monitor ___ asked to make a speech at the meeting.A. isB. wasC. areD. were答案B. 注:先从时态上考虑。
这是过去发生的事情应用过去时,先排除A.,C.。
本题易误选D,因为The League secretary and monitor 好象是两个人,但仔细辨别,monitor 前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。
后面的职务用and 相连。
这样本题主语为一个人,所以应选B。
二、主谓一致中的靠近原则1)当there be 句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。
There is a pen, a knife and several books on the desk..There are twenty boy-students and twenty-three girl-students in the class.2)当either… or… 与neither… nor,连接两个主语时,谓语动词与最邻近的主语保crowd, class, company, committee等词后用复数形式时,意为这个集体中的各个成员,用单数时表示该个集体。

1.主谓一致是指英语中谓语在人称、数及意义方面要与作主语的名词或代词一致。
2.主谓一致分为语法一致、意义一致、就近一致。
(1)语法一致原则:主语和谓语在语法形式上保持一致。
主语为单数,谓语用单数;主语为复数,谓语用复数。
I often help him and he often helps me.(2)意义一致原则:主语和谓语在意义上单复数一致。
主语为单数,谓语用单数;主语为复数,谓语用复数。
The police are searching the woods for the murderer.(3)就近一直原则:当主语有两个或两个以上时,谓语动词由靠近它的主语确定。
并列主语的谓语一致1.And(1)两个单数名词用and连接,表示不同概念时,谓语用发复数。
Tom and Jack are close friends.(2)两个单数名词用and连接,表示同一歌人、同一个物,同一个概念,或表示不可分割的整体时,谓语用单数。
The singer and dancer is to attend our evening party.(3)被every,each,many a,no等限定的单数名词由and连接时,谓语仍用单数,其中,后一个限定词可以省略。
every ……and ……every,each……and……each,no……and……no, many a……and……many a。
Each boy and (each) girl has an apple.(4)一个单数名词被几个用and连接的并列形容词修饰时,可以指一件事或几件事,这种名词作主语,要根据意义一致的原则决定单复数。
Simple and plain living is a fine quality.生活简朴一种优良品质。
Ancient and modern history are the subjects we are studying.(5)由and连接的两个what的从句作主语时,要根据意义一致的原则决定单复数What he says and does do not agree.(言行不一致)What he says and does does not concern me.2.由either or, neither nor, not but, not only but also,or, nor连接的并列主语,谓语动词常和邻近的主语一致。
Grammar Subject and Verb Agreement 主语和谓语一致主谓一致:是指一个句子的谓语动词必须和主语的人称和数一致。
也就是说考查主语和谓语动词的单复数对应。
谓语动词用单数还是用复数,这不仅仅取决于主语的单复数形式,有的时候还要看懂主语的单复数意义,所以要揭开庐山真面目,找到句子中真正的主语。
主谓一致主要遵循的三个原则:语法一致,意义一致,就近原则。
语法一致,数决定谓语动词的单复数形式,即主语是第三人称单数或不可数名词,谓语用单数,主语是复数,谓语用复数。
意义一致,是说有的时候主语看似是复数,但其实是单数;有时,主语形式为单数,但意义为复数,谓语动词要依意义而定,也采用复数形式。
“这就要考虑主语的单复数意义了。
就近原则,是指一些特殊短语做主语,比如,neither…nor,either…or,not…but…,not only…but also等,谓语动词用单数形式还是用复数形式,取决于最靠近他的主语。
谓语动词的变化一、就近原则(1).由“or,either...or...,neither...nor...,not only...but also...,not…but…”等连接的并列主语,谓语动词用单数形式还是用复数形式,取决于最靠近他的主语。
Either my wife or I am going. Not only you but also he is ready to leave.Neither you nor I am fit for the work.Neither you, nor I, nor anyone else knows the answer.(2).“There be +名词”句型中的主语不止一个时,谓语通常和最近的主语保持一致。
There is a book and three pens on the desk.二、谓语动词用复数的情况(1).由“both…and…”连接两个单数名词作主语时,谓语动词通常用复数形式;如:Both bread and butter are sold out.(2).“people,police,cattle”等集体名词作主语,谓语用复数。
主谓一致详细讲解(附习题)主谓一致(一)一、主谓一致三原则主谓一致是指谓语动词与主语在人称和数上保持一致,主谓一致必须遵循三原则:1). 语法一致原则 (grammatical concord)2). 意义一致原则 (notional concord)3). 就近原则 (principle of proximity)1. 语法一致原则:指主语是单数形式,谓语动词用单数形式,主语是复数形式,谓语也用复数形式。
Tom is a good student. 汤姆是个好学生。
They often play football on the playground. 他们经常在操场上踢足球。
2. 意义一致:指主语形式上为单数,但意义为复数,因此谓语动词用复数形式;或主语形式上为复数,但表示单数意义,这是谓语动词用单数形式。
My family are having lunch now. 我们一家人现在正吃午饭。
Twenty dollars is too expensive for the book. 这本书20美元太贵了。
3. 就近一致:指谓语动词用单数形式还是用复数形式,取决于最靠近他的主语。
Not only the teacher but also his students like playing football.不仅老师喜欢踢足球,而且他的学生也喜欢踢足球。
There is a pen and some books on the desk. 课桌上有一支钢笔和一些书。
二、以-s 结尾名词的主谓一致1. 以“s"结尾的表示学科、游戏和疾病等名词,常用单数。
学科:economics(经济学);linguistics(语言学);mechanics(力学、机械学);statistics(统计学);electronics (电子学);logistics(后勤学);physics (物理学);genetics (遗传学);mathematics(数学);politics(政治、政治学)游戏:billiards(台球,弹子戏);cards(牌戏);bowls(保龄球);darts (投标游戏)疾病:diabetes(糖尿病);mumps(腮腺炎);measles(麻疹);rabies(恐水症;狂犬病)Mathematics seems easy to me.我似乎觉得数学不难。
主谓一致英语中,主语的单复数形式决定谓语动词的单复数形式。
主谓一致必须遵循以下三条原则:语法一致原则、意义一致原则和就近一致原则。
根据这三条原则,现从以下几个方面进行总结:一、并列结构作主语时的主谓一致1. 由and/both...and...连接的两个单数名词作主语时(两个冠词),谓语动词一般根据语法一致的原则用复数。
例如:A young man and a girl want to go there. 一个青年男子和一个姑娘想去那里。
【注意】如果在意义上指同一个人、同一件事或同一个概念时(一个冠词),谓语动词用单数形式。
例如:①A needle and thread was found on the floor. 在地板上找到了针线(穿了线的针)。
②The teacher and writer is her friend.这个既是是教师又是作家的人是她的朋友。
2. 一个单数名词同时被and连接的两个不同的形容词修饰,表示两个不同的概念时,谓语动词用复数。
例如:Ancient and modern history are the subjects we are studying.古代史和现代史是我们目前学习的课程。
【注意】如果在意义上指同一个人、同一件事或同一概念时,谓语动词用单数。
例如:The last and most difficult lesson is lesson14. 14课是最后一课也是最难的一课。
3. 当each...and each...,every...and every...,no...and no...,many a...and many a...结构作主语时,谓语动词用单数形式。
例如:①No man and no animal is to be found on the moon. 在月球上没发现人和动物。
②Many a doctor and many a nurse is busy with their work.许多医生和护士都忙于他们的工作。
主谓一致归纳讲解主谓一致是指主语与谓语在人称和数上要相同。
在英语语法中,主谓一致是英语中最基本的语法规则之一,也是英语语法中最基础的语法点之一。
主谓一致在句子中很重要,因为它可以决定一个句子的语法结构和意义。
一般来说,主谓一致的规则很简单,主语是单数形式时,谓语也要使用单数形式;主语是复数形式时,谓语也要使用复数形式。
但是,在具体实践中,我们还需要注意一些更加细节的问题。
下面是主谓一致的一些常见归纳和讲解。
一、特殊情况当主语为集体名词时,主谓一致要看这个集体名词所表示的集体是否以整体作为主要意义,如果是以整体作为主要意义,那么谓语动词用单数形式;如果是以个体成员为主要意义,那么谓语动词用复数形式。
例如:1. The family is going to the park.(这个家庭打算去公园。
)3. The audience was very excited by the performance.(观众对表演非常兴奋。
)二、连接词导致的主谓一致问题在英语句子中,连接词和介词短语也会影响主谓一致性。
下面是一些常见的连接词以及它们在主谓一致中的作用。
1. Either…or…(要么…要么…)使用either…or…连接的两个词(或短语)都起到主语的作用,但它们中只有一个是实际的主语。
谓语动词的数应该与连接词后面的主语一致。
1. Either she or he is going to come to the party. (她或他中有一个人会来参加聚会。
)1. Neither the teacher nor the students are satisfied with the exam results.(老师和学生都对这次考试结果不满。
)3. Not only…but also…(不仅…而且…)三、主语和谓语之间的距离问题有时,主语和谓语之间有其他的词语,这可能会使人产生一些主谓一致的困惑。
1. There be 句型There be句型中的主语是there,其后紧跟着一个名词或名词短语。
语法点解析主谓一致的用法与理解语法点解析:主谓一致的用法与理解主谓一致是英语语法中一个重要的概念,它指的是主语与谓语在人称和数方面保持一致。
准确理解和正确运用主谓一致是写作中的关键之一。
本文将对主谓一致的用法与理解进行详细解析。
一、基本概念主谓一致是指主语与谓语在人称和数方面保持一致。
当主语是单数形式,谓语动词也要用单数形式;当主语是复数形式,谓语动词也要用复数形式。
主谓一致是英语思维逻辑的体现,它使文章的表达更加准确、流畅。
二、人称一致人称一致指的是主语与谓语在人称方面保持一致。
一般情况下,第一人称的主语与谓语使用第一人称形式,第二人称的主语与谓语使用第二人称形式,第三人称的主语与谓语使用第三人称形式。
例1:I am a student. (我是一个学生)例2:You are my friend. (你是我的朋友)例3:He is a doctor. (他是一名医生)三、数的一致数的一致指的是主语与谓语在数方面保持一致。
当主语是单数形式,谓语动词也要用单数形式;当主语是复数形式,谓语动词也要用复数形式。
例4:The dog barks. (这只狗在叫)例5:The cats play in the garden. (这些猫在花园里玩耍)例6:She eats an apple. (她吃了一个苹果)四、特殊情况除了基本的人称和数一致规则外,还存在一些特殊情况需要特别注意。
1. 不可数名词:对于不可数名词作主语,谓语动词一般使用单数形式。
例7:The information is correct. (这些信息是正确的)2. 复合主语:当主语由两个或多个单数名词或代词构成,且被并列连词and连接时,谓语动词用复数形式。
例8:Tom and Jerry are friends. (汤姆和杰瑞是朋友)3. 带有either...or, neither...nor, not only...but also等连词的主谓一致:当主语由either...or, neither...nor, not only...but also引导时,谓语动词的单复数形式取决于距离谓语动词最近的名词。
1.以一s结尾的名词的主谓一致
学科名词构词单复专有名词
2.用and连接的名词或代词作主语
意义上是两个人、物、概念(复数)例如:Jack and Tom
意义上是同一个人、物、概念(单数)
each……and each……(单数)every……and every……(单数)
3.集合名词的主谓一致

句法:复句
形容词性从句:定语从句
1.定语从句与同位语从句的区分
1)引导词与先行词之不同:同位语从句的引导词表达的是抽象、概念,这类词较少,而定语从句的先行词可以为任何名词;
2)结构:同位语从句的从属连词不在从句中充当任何语法成分,定语从句的关系代词在从句中必须充当一定的句子成分;
3)作用:同位语从句解释、说明抽象名词的具体内容,定语从句对名词进行限定、修饰;
2.限制定从与非限制定从的异同
1)逗号为标志2)插入语结构是非限制定语从句。
3.which/that与when/where/prep.+which/whose的区别:
4.that与which的选择:(三个层面分析)
句子层面:限定与否角度,非限定性定语从句用which
先行词层面:最高级;序数词;不定代词anything,nothing,little,all,everything;被next,last,only,very等修饰,用that
5.关系代词的省略
1作主语不可以省略2作宾语可以省略3定语从句的先行词the way(in which)所带的in which可以省略
6.限制性定语从句中可出现的插入语结构:
sb.+think;believe;suppose;know;feel;wonder;say;be
afraid
7.as与which用作关系代词的区别:
1)as与the same,such,so,as关联使用;
2)as和which都可以引导非限定性定语从句,但as的在句中的位置比较灵活,可出现在句首、句中,而which只能出现在句中。
名词性从句
一个主句和一个或一个以上的从句组成的句子称为复合句。
主句是句的主体,从句只用作句子的一个成分而从属于主句,从句种类由从句在句中所起的作用而定。
充当主语、宾语、表语、同位语、定语和状语的从句分别称为主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句。
其中主语、宾语、表语和同位语从句在句中的作用相当于名词通常在句中所起的作用,因而统称为名词性从句(nounclause)。
1)引导这些从句的词主要有三类:
1.从属连词:that(无词义),whether(是否),if(是否)
2.连接代词:who,whom,whose,what,which
3.连接副词:when,where,why,how
2)主语从句:
主语从句在句子中从当主语,在主语从句所在句子结构形式是“从句+谓语”,如:
That the sea covers about three-fourths0f the earth's surface is well known.众所周知海洋约占地球表面的四分之三。
对于主语从句要注意主语谓语一致性的原则:句子的主语是主语从句时,谓语部分应该使用单数的形式,如:
When she went there and what she did are still uncertain.也是什么时候去哪里的,她在哪里做了什么,这些都还不能确定。
3)宾语从句
宾语从句在句子中充当作动词或介词的宾语,如:
They tell me(that)the math course is difficult.(宾语从句)他们告诉我数学课程很难。
4)表语从句
表语从句谓语be动词的后面,充当句子的表语。
My problem is how we call reduce this high temperature.我的问题是我们怎么能够降低这样的高温。
1)下列的抽象、概念性名词常引出同位语从句
appeal,belief,conclusion,condition,conviction,doubt,evidence,fact,fear,feeling,ground(s),hope,idea,likelihood,message,news,opinion,order,plan,point,possibility,problem,promise,reply,pmof,proposal,question,rumor,story,suggestion,suspicion,theory,thought,truth,trouble,undestanding,worry
2)连词通常为从属连词that,但有时由于名词内容的需要,也可由whether及连接副词why,when,where,how引导。
that只充当连接手段,不作其后句子成分,不表示任何意义;其它词表示时间、地点、原因等。

3)同位语从句有时与抽象、概念性名词之间有插入语。
5.连词难点解析:
A.whether与if在引导名词性从句时的区别
1)主语从句、介词宾语从句只能用whether引导;
2)whether0r not可以连在一起用,而if or not则不能,or not 只能放在句末;
3)在question,ask后面一般只用whether,question的同位语从句也用whether;
4)后接不定式时,只能用whether。
B.what的用法;
C.whoever与whomever分别是主格与宾格。
它们的出现取决于它们在从句中作主语还是作宾语;
D.宾语从句否定转移:动词believe,expect,fancy,imagine,suppose,think后的宾语从句如为否定式,一般将否定词转移到主句谓语上。
