主谓一致，顾名思义，指一个句子的主语和谓语在人称和数上保持一致。人称上的一致很简单，我是用I am，你是用You are, 他是用He is.
数上的一致，一般规则为主语是单数，谓语也用单数。主语是复数，谓语也用复数。就近原则：
就近原则例句：1. There is a pen and two books on the desk.
桌上有一支笔和两本书。
2.Not you but I am to blame.
不该怪你而该怪我。
3.He or I am wrong.
他或是我错了。
4.Neithe ryou nor he is tired.
你和他都没累。
也称“邻近原则”“就近一致原则”(Proximity），即：谓语与靠近的名词、代词（有时不一定是主语）在“人称、数”上一致。
I.在正式文体中：
1由下列词语连接的并列主语：
"there be＋句型; or ; either …or；nor; neither…nor；whether…or；not…but; not only…but also" ; 等。
eg：
①What he does or what he says does not concern me .
他的行为或言谈都与我无关。
②Neither you nor I am wrong .
你和我都没错。
③Not you but your father is to blame .
不是你，而是你父亲该受责备。
④Not only you but(also) he is wrong .
不仅你错了，他也错了。
2在倒装句中：谓语可与后面第一个主语一致。
eg.
①In the distance was heard the clapping of hands and the shouts of the people . 在远处，能听见鼓掌声和人们的呼喊声。
②There is(are) a pen and some books on the desk .
桌上有一支钢笔和几本书。
II.非正式文体中：
1有时依“就近一致原则”，但也可依“意义一致原则”或严格地依“语法一致原则”。
eg.
Neither she nor I were there (意义一致)
我和他当时都不在那儿。（非正式）
Neither she nor I was there .（
就近一致）（译文同上句）（正式）
2但是，如果依“就近一致原则”而与其他两项原则相矛盾时，则常常认为是不太合符规范的。
eg.
No one except his own supporters agree with him
.仅他自己的支持者同意他的意见。（依“就近”和“意义”一致的原则；但语法上，“No one ”才是主语，谓语要改成“agrees”。“写作中”一般要依“语法一致”原则。
采用“就近原则”的两个典型用法即谓语动词的单、复数形式取决于最靠近它的词语。
连词or, not…but…, either…or…, neither…nor…, not only…but also…等连接的并列主语，谓语动词的数与靠近它的主语一致。
如：
Not his parents but he doesn’t want to go.
是他的父母亲不想去而不是他不想去。
Neither you nor I am a stranger here.
你和我都不是刚来这里。
Does neither he nor his classmates know the secret?
他和他的同学都不知道这个密秘？
当there be后有两个或几个并列的主语时，be的数由与其靠得最近的那个主语一致。
如：
There is an apple, two pears and some oranges on the plate.
盘子里有一个苹果，两个梨子和一些桔子。
There are two pears, some oranges and an apple on the plate.
盘子里有两个梨子，一些桔子和一个苹果。
由 or，not only … but also …， either … or …， neither … nor …，not … but …等连接两个名词作主语时，谓语动词的单复数形式要根据就近原则来确定。
如：
You or he is going to be sent to study abroad .
He or we are going to be sent to study abroad .
“名词 介词 / 介词短语（ with，together with，along with，as well as 等） 名词”作主语时，谓语动词的单复数由介词前的名词的单复数形式决定。
如：
Tom as well as his parents enjoys fishing .
You as well as your brother have been accepted .
主语从句、不定式或动名词作主语时，谓语动词要用单数形式。
如：
What we can’t get seems better than what we have .
Taking more exercise is good for your health .
定语从句中，当先行词在从句中作主语时，从句谓语与先行词的人称和数保持一致；但“ one of 名词复数”作先行词时，如在one 前有 the，the very，the only 等词修饰时，从句谓语动词要用单数形式，若没有，则用复数形式。
如：
He is one of the students who have been praised by the headmaster .
He is the only one of the students who has been praised by the headmaster .
there be 句型中，be 的单复数形式由其后的名词决定，如果有两个或两个以上的名词，则按就近原则决定。
如：
There is only a desk in the room .
There is only a desk and two chairs in the room .
There are two chairs and a desk in the room .
“the 形容词”作主语表示一类人时，谓语动词一般用复数形式。
如：
The rich don’t understand the life of the poor .
The wounded have been given careful attention .
中学就经常考以下4个就近原则的知识点。
就近原则，也就是说，句子中的谓语动词是由最靠近它的名词或者代词来决定其用单数还是复数这个问题。
1.There be 句型 There is an apple ,a pear and two bananas in the bag.( an apple 最靠近be 的位置，an apple是单数，所以谓语用is )
=There are two bananas , an apple and a pear in the bag .（two bananas最靠近be 的位置，two bananas是复数，所以谓语用are）
2.neither...nor... Neither you nor he is right.（这句有两个主语，一个是you 一个是he ,由于he 最近谓语的位置，所以谓语用is ) = Neither he nor you are right.
3.either...or... Either they or Jim is going to Shanghai next Saturday.(jim 最近谓语，所以用is )= Either Jim or they are going to shanghai next Saturday.（they 最靠近谓语，所以用are）
4.not only...but also... Not only Ann but also her parents stay at home every Sunday.(her parents 最近谓语，所以谓语stay用复数 ) = Not only Ann's parents but also she stays at home every Sunday.（ she 最近谓语，所以谓语用第三人称单数 “stays "）
【就远原则】（就前原则）谓语动词与前面主语一致
代表词汇：as well as；（together/along）with；rather than；except；besides；but；including；in addition to；apart from
就远原则
就远原则即谓语要与较远的主语保持一致。
当主语后面跟有由but, except, besides, like, with, as well as, no less than, along with, in addition to, rather than, together with等引出的短语时就采用“就远原则”。
Everybody except you likes me.
除了你，大家都喜欢我。
就前原则例句：
1.The son,as well as his parents, wants to go there.
不但儿子想去那儿，而且他的父母也想去。
2.The teacher,as well as the students, is interested in the activity.
老师也和同学们一样对这项活动有兴趣。
3.Dessert fruit,like strawberries and pears is very popular.
像草莓和梨这样的餐后水果是很受欢迎的。
4.John,rather than his roommates,is to blame.
约翰，而不是他的室友，应该受到责备。
5.My father,no less than I,is a base-ball fan.
我的父亲不亚于我也是个棒球迷.
6.Jim,together with his classmates,has seen the film.
吉姆和他的同学都看过这部电影。
7.All the students,including Tom,are leaving.
所有的学生，包括汤姆都走了。
8.No one except(but) me knows about this news.
除了我没有人知道这个消息。
就远原则谓语与比较远的那个主语保持一致。
“名词 介词 / 介词短语（ with，together with，along with，as well as, except等） 名词”作主语时，谓语动词的单复数由介词前的名词的单复数形式决定。比如：
1. Nobody but two students is in the classroom.
除了这两个学生，没有人在教室
2. Everybody except you is down on me.
除了你，大家都看不起我。
3. A woman with two children has come.
一位妇女带着两个孩子已经来了。
4. The son, as well as his parents, wants to go there.
不但儿子想去那儿，而且他的父母也想去。
复习：
若是and来连接，兼职并列细分辨。
and连接两个主语时，如：The teacher and the writer为并列主语，谓语动词应为复数。The teacher and writer则是一人双重身份，谓语动词应为单数。
The teacher and the writer are coming here.
The teacher and writer is coming here.
