语法概说
主谓一致命题趋势与预测
根据对主谓一致部分全国各地试题的分析可知，今后该部分将是重点考查点之一。其考查重点为：
1、主谓一致的语法一致原则
2、主谓一致的整体一致原则
3、主谓一致的就近一致原则
4、主谓一致的意义一致原则
5、主谓一致的附加原则
考点诠释
一、由or, either... or... , neither... nor... , not only...but also... , whether...or...等连接并列主语时,常采用就近原则,动词与最靠近的主语保持一致。
考例Not only Jim but also his sister ______a few cities in the south since they came to China．[临沂市]
A．will visit B. has visited C．have visited D ．visited
[答案]B ．[解析]本题既考查时态，又考查并列连词not only．．．but also的用法。由时间状语since they came to China，可判断用现在完成时，排除A、D两项；not only．．．but also连接两个并列的主语时，谓语动词要用就近原则。
Neither Jim nor his cousins _______to America, but _____of them know the country very well. [07年潍坊市]
A．have been；a11 B. have been; both C has been; all D．has been; both
[答案]B．[解析]考查neither．．．nor的用法，以及both与all的区别。neithernor连接两个主语时，谓语用就近原则，cousins是复数，谓语用have been，排除C和D项；指两者用both。
二、 the number of + 复数名词,主语是the number(数量),谓语动词用单数;a number of +复数名词,主语是复数名词,a number of作定语, 相当于many,谓语动词用复数。
考例Look! There _______ playing with the tourists on Yinhe Square. (2004包头)
A. are a number of deer B. are a number of deers
C. is a number of deer D. is a number of deers
答案：A。该题考查的是主谓一致。这个句子的主语是a number of deer, 是个复数概念，因此谓语动词应用复数形式。（deer单复数相同）
The number of ________ in our class ________ fifty. (2004山东烟台)
A. student, is B. the students, are C. the students, is D. students, are
[答案]: C
[命题立意]：本题考查主谓一致的用法。
[试题解析]：the number of 后接复数名词，作主语时，其谓语动词用单数形式。故应选C。
三、动词不定式、动名词以及名词性从句作主语时,谓语动词常用单数形式。
考例As the saying ________,Where there is a will; there is a way. [昆明市]
A. go B. goes C. going D. went
[答案]B．[解析] the saying为第三人称单数形式，所以谓语动词用goes。
但what从句作主语而表语是复数时,谓语动词常用复数。
What we badly need here are experienced teachers. 我们这里急需的是有经验的教师。
四、and连接的两个单数名词作主语。
考例Trees and flowers ________every year to make our country more beautiful. [陕西省]
A. is planted B. was planted C. are planted D. were planted
[答案]C．[解析] every year说明本句表示的是一般现在时的概念，去掉B、D项；trees and flowers表达复数意义，所以选C项。
五、表示时间、距离、金钱、体积或数字等的词语作主语且表示总量时，谓语动词用单数。
考例

A．is；is B are；is C．are；are D．is；are
[答案]B ．[解析] 答案为B。shoes作主语时，谓语动词应用复数形式；five dollars是一个整体，应按单数对待。
How time flies! Ten years ________ passed. (2004天津)
A. have B. has C. is D. are
答案：B。该题考查的是主谓一致。Ten years通常被看作是一个时间整体，谓语动词用单数形式。
六、就近原则
--There__________ no milk in the fridge. Could you get some for me, Dick?
--All right, Mum. [福州市]
A. is B. are C. was D. were
[答案]A．[解析]本题考查there be句型中be的数及时态，be在数上要与最近的主语保持一致.句子的主语是不可数名词，所以be应使用单数形式，B、D两项可以排除。
Not only Jim but also his sister ______a few cities in the south since they came to China．[07临沂市]
A．will visit B. has visited C．have visited D ．visited
[答案]B ．[解析]本题既考查时态，又考查并列连词not only．．．but also的用法。由时间状语since they came to China，可判断用现在完成时，排除A、D两项；not only．．．but also连接两个并列的主语时，谓语动词要用就近原则。

语法回顾
主谓一致
1. 语法一致的原则
2. 意义一致的原则
3. 邻近一致的原则
谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。
在英语中，谓语动词必须和主语在人称和数上同主语保持一致，叫做主谓一致。通常采用下列三个原则来处理，即：语法形式一致的原则、逻辑意义一致的原则、就近（或毗邻）一致的原则。
一、语法形式一致的原则，即在语法形式上取得一致。如：主语为单数形式，谓语动词用单数；主语为复数形式，谓语动词也采用复数形式。但须注意下列几种情况：
1.以单数名词或代词、动词不定式短语、动名词短语或从句作主语时，谓语动词用单数。 例如：
Much land has been deserted in this area in the past few years.在过去的几年中，这个地区的许多土地已经沙化。
To start smoking is quite easy, but to give it up needs courage.开始吸烟很容易，但是要戒烟却需要勇气。
Reading English newspapers is a good way of improving you English. 阅读英文报纸是提高你英语水平的好方法。
What you need most is to have a good sleep.你所需要的就是好好睡一觉。
How you can get there is a problem. 你怎么到那儿去还是个问题。
[注意：]由what引导的主语从句，后面的谓语动词多数情况用单数形式。但若表语是复数或what从句是一个带有复数意义的并列结构时，主句的谓语动词用复数 。例如：
What I bought were three English books.我买的是三本英语书。
What I say and do is (are) helpful for you.我所说的和做的对你是有帮助的。
2、由and 或both...and来连接并列主语时，谓语用复数。例如：
Swimming and walking are good exercises.游泳和散步都是好运动。
He and I were classmates when we were at college.他和我在上大学时是同学。
Both John and Ann have got pen-friends.约翰和安都有笔友。
Both Zhou Lan and Yang Pei like sports.周兰和杨蓓都爱好体育。
[注意]1）但是，并列主语如果表示同一个人、同一事物或同一概念时，谓语动词用单数形式（这时and后的名词前没有冠词）。例如：
The manager and secretary was absent at the meeting.经理兼书记没有出席会议。
The manager and the secretary are busy now.经理和书记现在都很忙。
Their teacher and friend is Mr. Li.他们的老师和朋友是李先生。
2)由and连接的并列单数主语前如果分别被no, each, every或many a ，more than one修饰时，其谓语动词用单数形式。 例如：
In our country every boy and every girl has the right to receive education.在我们国家里，每个男孩和女孩都有权利受教育。
Each man and each woman is asked to help. 每个男士和妇女都被请来帮忙。
Many a student is having practice in that factory. 许多学生正在那家工厂实习。
More than one student is interested in the book.不止一个学生对这本书感兴趣。
[注意] 在more than one＋单数名词作主语时，若在There be句型中，亦可用复数。 如：
There is/are more than one man here. 这儿不止一个人。
3、如果主语是单数，尽管后面跟有(together) with, as well as, like, but, except, besides，including, no less than, rather than ,as much as，more than，along with in addition to等介词短语，其谓语动词仍用单数形式；若主语为复数，则谓语动词也用复数。例如：
An English teacher together with some students has climbed to the top of the mountain.一位英语老师和几个学生已经爬到了山顶。
Mary as well as her friends likes this painting.玛丽和她的朋友都喜欢这幅画。
No one except my close friends knows anything about this matter.除了我的亲密朋友谁也不知道这件事。
The teacher with a number of students is in the classroom.老师和许多学生在教室里。www.4zk5u.com
She, like you and Tom, is very tall.像你和汤姆那样她很高。
4、不定代词each, either, neither 和由 some, any, no, every 构成的复合代词作主语时，谓语动词用单数。 例如：
Each (of us) takes a cup of coffee.(我们)每人喝一杯咖啡。
Everyone knows smoking cigarettes is bad for health.大家都知道吸烟不利于身体健康。
Nothing is to be done 没有什么要干的事。
Everybody obeys the school rules; anybody who breaks the rules is punished.每个人必须遵守学校规则，任何人违反了规则将受到惩罚。
2）若后面的名词是不可数名词，它的谓语动词就要用单数；若它后面的名词是复数，它的谓语动词用单数或复数都可以。例如：
None of the sugar was left.没有剩下什么糖了。
None of us has (have) been to America.我们中没有人去过美国。
5.不定代词none 以及由none/either/neither＋of＋复数合词(或代词)构成的短语作主语时，谓语用单复数均可，这取决于说话人的意思。当说话人着眼于每一个都不.......或两个中的任何一个都不.......时，谓语动词用单数；当说话者着眼于所有的都不.......或两个中的全部都不.......时，谓语动词用复数。例如：
None know when that was. (强调所有的人) 没人知道这是什么时候的事。
None is so good as he.(强调每一个人) 没有人像他那么好。
None of them have / has a car.他们都没有小汽车。（他们没有一个人有小汽车。）
Neither of them know / knows the answer.他们两个全都不知道答案。（他们两个人谁也不知道答案。）
Neither of the article is (are ) interesting.其中没有哪篇文章有趣。
Neither of them have replied. 他们两个谁也没有答复。
Neither of them has replied. 他们两个谁也没有答复。
5、在定语从句中，关系代词that，who，which等作主语时，其谓语动词的数，应与句中先行词的数一致。例如：
It sounded like a train which/that was going under my house.那声音听起来就像有一列火车从我的房子底下开过似的。
People who study the think that there will be another big one soon.研究地震的人认为不久将还有一次大的地震。
The horse which is tied to the tree belongs to John.拴在树上的那匹马是约翰的。

Some of the energy that is used by man comes from the sun.被人类使用的一些能源来自太阳。
[注意]在以one of the＋复数名词为先行词的定语从句中，关系代词作主语时，谓语动词用复数；但如果one of the＋复数名词这个结构前有the only之类的修饰语时，其从句的谓语动词用单数。 例如：
This is one of the questions that have been asked by the students.这是学生提出的许多问题的一个。
Bob is one of my friends who are helping me with English.鲍勃是帮助我英语的朋友之一。
He is the only one of the officers who was invited to the ball here. 他是办公室唯一收到邀请参加舞会的人。
The head master is the only one of the teachers who knows Esperanton.校长是老师中唯一懂得世界语的人。
6、a lot of （lots of， plenty of， a head of， heaps of， the rest（majority） of ，some
（many，anymore，most， all等）of＋+名词构成的短语作主语时，其谓语动词的数要与of后面的名词（短语）保持一致。例如：

Plenty of English books are on the shelf.许多英语书在书架上。
注意：1）all单独作主语表示人时，谓语用复数；表示整个事件或事情时，谓语用单数。 如：
All are present. 所有的人都出席了。(表人)
All is well. 一切都好。 (表示整个事情或情况)
2）a number of+复数名词 作主语时，谓语动词用复数形式；The number of+复数名词作主语时，谓语动词用单数形式。例如：
