主谓一致的基本概念和分类所谓主谓一致，即谓语动词必须与主语在人称、数上保持一致。
主谓一致关系应遵循三项原则，即：语法形式上一致；语言意义上一致；就近原则。
一、语法一致是指主语和谓语动词必须在语法形式上保持一致关系，也就是说，主语是单数时，谓语动词用单数形式，主语是复数时，谓语动词应该用复数形式。
eg. Kate likes watching TV.I enjoy reading novels.They are interested in collecting stamps.1、代词each, another, the other, either, someone, somebody, everyone, everybody, anyone,anybody, something, anything, nothing, no one等作主语时，谓语动词要用第三人称单数形式。
eg. No one knows the fact.Someone is asking for you.Nothing is serious.•Each is used before a singular noun with a singular verb（each用在单数名词前面，谓语用单数）:·Each item was thoroughly checked.•Each can also be used before …of‟ and a plural noun. The verb should still be singular（each后面也可以加of,后复数名词，谓语仍然用单数）:·Each of these people has some useful talent or experience.2、主语后面跟有with, as well as, like, together with, along with, including, but, except, ratherthan, besides 等起连接作用的词带有他们的单、复数名词等，其谓语动词应根据这些词前面真正主语的人称、数相一致。
即：主语1，as well as/with/ along with etc+主语2，谓语（单复数与主语1一致）...eg. Mary, as well as her parents, is in China now.My mother with me has been invited.3、非谓语动词，名词性从句以及“疑问代词/副词+ 不定式”作主语时，谓语动词用第三人称单数形式。
eg. When and where we will hold the meeting is unknown.How to work out the problem is unknown.To learn English well is not easy.4、“more than one + 单数名词”尽管意义上不止一个，但其谓语动词也用单数形式。
同样“many a + 单数名词” 尽管意义上表示“许多”，但其谓语动词也用单数形式。
eg. More than one person has had the idea.Many a student is fond of music.Many a parent has had to go through this same painful process.5、and, both, all, few, several, many等修饰可数名词的复数形式作主语时，谓语动词用复数形式。
eg. All his friends have come.Many boys are fond of football.6、在倒装句中，谓语动词应根据后面的主语在人称、数上保持一致。
eg. Here comes a bus.7、两个主语，一个肯定，另一个否定，谓语动词的数与肯定主语相一致。
eg. I, not you, am the right person to do the work.二、意义一致即从意义上着眼处理一致关系，即：当主语在形式上是单数，意义上是复数时，谓语动词要用复数形式；当主语在形式上是复数而意义上是单数时，谓语动词要用单数形式。
1、表示总称意义的名词如：people, cattle, clothes, police等作主语时，谓语动词用复数形式，而没有生命的traffic, equipment, clothing等做主语谓语动词用单数形式。
eg. Your clothes are very dirty.The cattle are eating grass on the hillside over there.2、maths, physics, politics, news等名词作主语时，谓语动词用单数形式。
eg. Physics is interesting to learn.This news is the latest.3、名词如：family, team, crowd, crew, class, group, government, enemy, army, public或all等作主语时，如果作为一个单数（集体）看待时，谓语动词用单数形式；如果作为整体中的各个成员看待时，谓语动词用复数形式。
eg. My family is a small one, but my family all like watching TV.Our class is on the second floor, and our class work hard.4、“The rest / part / half / most / all/百分数词/分数词+ of + 复数名词”作主语时，谓语动词用复数形式，但“The rest / part / half / most / all/百分数词/分数词+ of + 不可数名词/单数可数名词”作主语时，谓语动词要用单数形式。
（即：看of后面的名词单复数来决定谓语动词单复数）eg. 2/3 of the workers are from Japan.The rest of the homework is usually done by me.5、表示“金钱，时间，距离，重量，容量，温度”等名词作主语时，谓语动词用单数形式。
eg. Ten days is enough.100 years is not long.6、“the + 形容词”作主语，表示“一类人”时（the poor穷人；the rich富人），谓语动词用复数形式；若指具体的某个人时，谓语动词用单数形式。
eg. The wounded are still in hospital.The new is from the USA; his name is Jim.7、trousers, shoes, boots, glasses, socks, gloves, compasses等作主语时，谓语动词用复数形式；若这些名词被this / a pair of 修饰时，谓语动词要用单数形式。
eg. Her trousers are black.This pair of trousers doesn‟t fit me.8、and 连接两个并列名词作主语，指同一个人或同一件物或同一概念时，谓语动词用单数形式。
And连接若干个被no, each, every, many a 修饰的单数可数名词作主语时，谓语动词用单数形式。
eg. The director and actor has come here.No worker and no boss is allowed to enter the lab.Every boy and girl is invited.9、Chinese, Japanese, deer, sheep, means 等单、复数同形的名词作主语时，他们自身在句中的内容决定其谓语动词的单、复数形式。
eg. Chinese is one of the eight subjects we must study at school.These five Chinese are studying English in London.10、代词在句中作主语，谓语动词的数应与其意义相一致，主要有以下几种情况。
①疑问代词what, which, who的单、复数意义，按照说话人的意图决定。
eg. What is/are today‟s topic/topics?Who lives/live in the room?②连接代词what的单复数意义，取决于后面表语的数。
eg. What he needs is just water.What he needs are books.③关系代词that, which, who的单复数意义由其先行词决定，特别应注意：“one of+ 代词/复数名词”后跟有定语从句时，从句的谓语动词用复数形式，而“theone / the only one of + 代词/复数名词”后跟有定语从句时，从句的谓语动词却要用单数形式。
eg. John is one of the students who have passed the test.He is the only one of the boys who hasn‟t been to Beijing.④在“it +be +被强调部分+ that / who…”结构中be用单数形式。
如被强调部分是原句的主语，that/who后面的谓语动词的单复数需和被强调部分的人称单复数保持一致。
eg. It is I who am wrong.三、就近原则指谓语动词应根据最靠近谓语动词的那个主语单、复数形式相一致。
主要有如下两种情形：1、在There be存在句中。
eg. There is a boy and three girls in that room.There are four deer an done bear in the zoo.2、由or, either… or…, neither… nor…, not… but…, not only… but also…连接两个并列主语时。
eg. Either you or I am going there.Not Betty but I am not right.总结：语法一致：不定代词，就远原则，非谓语动词，从句，修饰可数不可数名词的量词，倒装句等意义一致：集体名词，family等，学科，金钱等表示整体意义，and连接no,every, many a 等，代词，the+adj等就近原则：not only…but also, or, either… or…, neither… nor…, not… but…等。
