2021年高三英语语法专题主谓一致 Word版含答案在英语句子里，谓语受主语支配，其动词必须和主语在人称和数上保持一致，这就叫主谓一致。

寻其规律，大致可归纳为三个原则，即语法一致、逻辑意义一致和就近一致原则。

一、就近一致原则1．由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等连接两个或两个以上的并列主语时，通常根据就近一致原则，谓语动词要与离它最近的主语在数上保持一致。

Neither his parents nor I am able to persuade him to change his mind.他的父母和我都不能说服他改变主意。

2．here/there引导一个句子而主语又不止一个时，通常根据就近原则，谓语动词要与离它最近的主语在数上保持一致。

Here is a ruler，a few pencils and two copybooks.这里有一把尺子、一些铅笔和两本字帖。

二、意义一致原则1．谓语动词必须用单数的情况(1)表示学科的名词以及works(工厂)，news(消息)等作主语时，虽然本身为复数形式，但表示单数意义时，谓语动词仍用单数。

Politics is his favorite subject.政治是他最爱的科目。

(2)表示某些组织机构的名词、书/报名、国名、地名等作主语时，虽然形式上是复数，但所表示的意义是单数，所以谓语动词用单数。

Do you know when the United Nations was set up?你知道联合国是什么时候建立的吗？2．谓语动词必须用复数的情况表示总称意义的名词，如people，police，public，cattle等作主语时，谓语动词用复数。

The police are searching for the murderer.警察正在搜捕杀人凶手。

英语主谓一致真题汇编（含答案）及解析英语主谓一致真题汇编(含答案)及解析一、主谓一致1．---I saw Tom's father bought lots of books yesterday.---That's not strange. Not only Tom but also his father _______reading.A．enjoy B．enjoys C．enjoyed【答案】B【解析】【详解】句意：——昨天我看见汤姆的爸爸买了许多书。

——那不奇怪，不仅汤姆而且他爸爸喜欢读书。

根据not only..but also… 不仅……而且……，连接句子的两个主语时，谓语动词就近原则，根据句意说明一种情况，用一般现在时态，根据his father单三，所以谓语动词用单数形式；故选B2．Alice, together with her classmates punished for breaking the school rules last week. A．is B．are C．was D．were 【答案】C【解析】【详解】句意：艾丽斯和她的同学上周因违反校规而受到惩罚。

考查一般过去时和主谓一致。

根据last week可知句子时态应用一般过去时，排除A、B选项；together with her classmates在句中作状语，主语是Alice，第三人称单数，所以谓语动词也要用第三人称单数形式，排除D选项；故答案选C。

3．Everyone except Tom and Jim _______ going to visit some friends in Shenzhen.A．is B．are C．am D．be【答案】A【解析】【详解】句意：除了汤姆和吉姆之外，每个人都会去拜访在深圳的一些朋友。

Except意为“除了”，引起的结构跟在主语后面，不能看作是并列主语，主语如是单数，其谓语动词仍然用单数形式，本句主语是everyone，不定代词，谓语动词用be动词单数is，故选A。

（完整版）高考英语专题复习主谓一致（附答案）.doc高考英语专题复习主谓一致（附答案）I.考点分析一、概述主谓一致是指句子成分之间或词语之间在人称、性、数等方面的一致关系。

处理主谓一致一般应遵循以下三条原则：1.语法一致，即在语法形式上取得一致。

例如，主语为单数形式，谓语动词也为单数形式；主语为复数形式，谓语动词也采取复数形式。

a. The number of errors was surprising.b. Julia and her twin sister naturally look a lot alike.2.意义一致，即从意义着眼处理一致关系。

a. The crowd were fighting for their lives. (单形名词主语要求复数谓语动词，下划线部分表示一个整体中的成员 )b. Five minutes is enough. ( 复数名词单数谓语动词，下划线部分表示一个数目)3.邻近原则，即指谓语动词的形式与邻近的名词一致。

a. A man of abilities are needed（.动词 are 不与主语 a man一致，而与其邻近的复形名词a bilities 形式上一致。

二、主谓一致注意要点：1.当名词词组中心词为表示度量、时间等复数名词时，往往可根据意义一致的原则，把这些复数名词看作一个整体，谓语动词采取单数形式。

a. The dollars is not enough.b. Three months passes in no time at all on the ranch.如果明显地指一个个个体，则要根据语法一致地原则，谓语动词用复数形式。

a. There are two sliver dollars in each of the stockings.2.如果名词词组中心词是all, most, half, the last, the rest, the remainder等词组时，其主谓关系一般遵循意义一致的原则：如所指为复数意义，谓语动词用复数形式；如所指为单数意义，则谓语动词用单数形式。

高考英语主谓一致练习题20题(带答案)1. In the library, there ____ a large number of books on various subjects.A. isB. areC. hasD. have答案解析：B。

本题考查的是存在句中的主谓一致。

“a large number of + 复数名词”表示“许多”，作主语时，谓语动词要用复数形式。

A选项“is”用于单数主语；C和D选项“has”和“have”表示“拥有”，这里是存在句，不是表示所属关系，所以不选。

2. Not only the students but also their teacher ____ going to the museum tomorrow.A. isB. areC. wasD. were答案解析：A。

本题考查的是主谓一致中的就近原则。

“not only...but also...”连接两个并列主语时，谓语动词与靠近它的主语保持一致。

在这个句子中，靠近谓语动词的主语是“their teacher”，是单数，再根据“tomorrow”可知是一般将来时，这里用“be going to”结构，所以选“is”。

B选项“are”用于复数主语；C和D选项“was”和“were”是一般过去时，不符合句子时态。

3. The number of people who ____ interested in this new product ____ increasing.A. are; isB. is; areC. are; areD. is; is答案解析：A。

“the number of + 复数名词”表示“……的数量”，作主语时，谓语动词用单数形式，所以第二个空填“is”；“who”引导的定语从句修饰“people”，“people”是复数，所以从句中的谓语动词用“are”。

B选项主谓一致判断错误；C选项两个空都错误；D选项第一个空错误。
