说起主谓一致，要说的东西可真不少，看看以下归纳的难点，是不是你所想迫切解决的问题——
一、名词及代词作主语
1.单数名词、不可数名词及单数代词作主语，谓语用单数；复数名词及复数代词作主语，谓语用复数。例如：
Tom is swimming in the river.
A lot of books have been bought by them.
2.people，police 及 cattle 等集合名词作主语，谓语用复数。audience, family, group, team, army, public 等集合名词作主语要依照具体情况来定：若表示整体情况，谓语用单数；若指其中成员的具体情况，谓语用复数。例如：
The police here carry weapons.
Our baseball team is the strongest in the league.
Our baseball team are having breakfast.
3.表示某段时间、某一重量、长度、距离、价值等名词的复数形式作主语，谓语大多用单数形式。例如：

The goods belong to Mr Wang.

6. “分数，百分数，the rest， some， most，half 等＋名词或代词”构成的短语作主语, 谓语动词的数往往与 of 后面名词的数或所指的意义保持一致”。例如：
Only 40 percent of the students in the class are boys.
Twenty percent of the class is (are) absent because of illness.
7.“a number of＋复数名词”构成的主语，谓语用复数;“the number of＋复数名词”构成的主语，谓语用单数。例如：
The number of traffic accidents has increased.
A number of children like this song.
8.国名、书名、剧名、报名、山名、水名等专有名词作主语，谓语用单数；某些带有集体意义的专有名词如俱乐部、航空公司、企业、山脉、群岛、瀑布等作主语，动词用复数。例如：
The B.B.C. have just finished today?謘s broadcast programme.
9.“表示数量单位的复数名词＋of＋不可数名词”作主语，动词用复数。例如：

11.在“such＋be＋名词”这一结构中，be 的数往往与其后面名词的数保持一致。例如：

二、动名词及不定式作主语
1.单个动名词或不定式作主语，谓语用单数。例如：
Making speeches is not her strong point.
Growing flowers needs constant watering.
2.由 and 连接的两个(或多个)动名词或不定式作主语，如果并列的动名词或不定式语义相同或相似，谓语用单数；如果语义不一致，则谓语用复数。例如：
Lying and stealing are not right.
To love and to be loved is sweet to me.
Weeping and wailing does nothing towards solving the problem.
Reading Ibsen and solving maths problems are different assignments.
三、“the＋某些形容词或分词”作主语
dying, young, old, blind, rich, sick,
wounded，poor 及 dead 等形容词或分词与定冠词搭配，功能相当于复数名词，代表整个类别，故作主语时谓语用复数。例如：
The old in
The wounded have been saved.
四、there be 结构的主谓一致
在“there be＋名词”这一结构中，be 的数与后面的(第一个)名词(即主语)的数保持一致。例如：
There is a bike, two tables and three chairs in the house.
There are three chairs, two tables and a bike in the house.
五、名词性从句作主语
1.由 that, where, when, whether, how 等词引导的名词性从句作主语，主句的谓语常用单数形式。例如：
How they can finish their work is still unknown.

2.由 what 引导的名词性从句作主语，谓语一般用单数(表语是复数时也可用复数)；如果 what 从句是带有复数意义的并列结构，主句的谓语用复数。例如：

2.“each＋of＋复数名词”作主语，谓语动词用单数比用复数好；“both of＋复数名词”作主语，谓语用复数。例如：
Each of the girls like(s) dancing.
Both of them have given up smoking.
3.none 及“none of...”结构作主语，none 指代不可数名词作主语，谓语用单数；指代复数名词作主语，强调全体，谓语用复数更好一些；着重个别，则用单数较好。例如：
None of the money is yours.
None of us have／has ever been abroad.
七、由 or 连接的并列结构作主语
1.由 or 连接的并列结构作主语，谓语动词的形式按就近原则处理。例如：

八、由 and 连接的并列结构作主语
1.由 and 并列的单数名词被 every，each 或 no 修饰，谓语用单数。例如:

2.由 and 并列的单数名词前都有 the，表示主语是两个或多个不同的人或物，谓语用复数；若只有第一名词有 the，后面的没有，表示主语是同一人或事物，谓语用单数。例如：
The poet and writer has come. 那位诗人兼作家来了。
The poet and the writer have come.那位诗人和那位作家来了。
但如果 and 连接的两个名词虽指两个人，但表示同一概念，谓语仍用单数。例如：
John and Alice at the same bridge table is unthinkable. 约翰和爱丽斯在同一张桥牌桌上玩真是不可思议。
3.the husband and wife，father and mother，mother and daughter 这类已成短语的名词作主语，谓语往往用单数。例如：
Father and mother is husband and wife; husband and wife is one flesh. 父母是夫妻；夫妻是一体。
九、其他并列结构作主语
由 neither...nor，either...or，not only...but also 连接的两个主语，谓语动词的数通常按就近原则，即与后面的主语保持一致；如果是疑问式则以前面的主语为准。例如：
Either you or I am wrong.
Either I or you are wrong.
Am either I or you wrong?
十、“主语＋附属结构”作主语
主语+ with， along with， together with，like，unlike，besides，but，except，including，as well as，as much as，rather than，more than，no less than，and not 等构成的结构作主语，谓语动词的数通常与前面的主语保持一致。例如：

十一、强调句及倒装句的主谓一致
1.如果被强调的成分是原来句子的主语，引导词 that (或 who) 后面谓语的数与被强调的成分保持一致。例如：
①I am a doctor.→It is I who am a doctor.
He is a doctor. →It is he who is a doctor.
②I have read the book.→It is I who have read the book.
He has read the book. →It is he who has read the book.
2.倒装句谓语动词的数与后面的主语保持一致，即谓语后面的主语是单数，动词用单数；谓语后面的主语是复数，动词用复数。试比较：
①A building stands in front of us.
→In front of us stands a building.
②Two buildings stand in front of us.
→In front of us stand two buildings.
③Rows of fruit trees were on either side.
→On either side were rows of fruit trees.
十二、定语从句的主谓一致
1.引导词 who, that 或 which 在定语从句中作主语，定语从句谓语动词的数与定语从句所修饰的名词或代词的数保持一致。例如：
The cake which is on the table is yours.
The cakes which are on the table are yours.
如果定语从句修饰前面的整个句子，定语从句的谓语动词用单数。例如：
They are hollow, which makes them very light.
He married Mary, which was very natural.
2.“one of＋复数名词＋定语从句”结构
如果 one 前面没有限定词，这个句型中的“复数名词”是先行词，定语从句的谓语动词用复数；如果 one 前面有 the only, the first, the last, the right 等限定词修饰，则 one 是先行词，定语从句的谓语动词用单数。试比较：
John is the only one of the students who has the keys. 那些学生中只有约翰有钥匙。
John is one of the students who have the keys. 约翰是那些有钥匙的学生中的一员。
