主谓一致
主谓一致的原则
主谓一致是指主语和谓语在人称和数上保持一致。
1. 语法一致原则: 主语和谓语在人称和数上一致。主语是单数形式, 谓语动词也采用单数形式; 主语是复数形式, 谓语动词也采用复数形式。
2. 意义一致原则: 谓语的单复数取决于主语的意义。当主语形式上为单数，但意义上却是复数时，谓语根据意义用复数形式；当主语形式上为复数，但意义上却是单数时，谓语根据意义用单数形式。
3. 就近一致原则: 谓语动词的形式与邻近的主语在人称和数上一致, 即谓语动词的单、复数形式取决于最靠近它的主语的单、复数形式。
主谓一致的具体应用
1. 名词作主语
(1) 集体名词作主语，如果表示整体概念，谓语动词用单数形式;如果强调个体，谓语动词用复数形式。常见的这类名词有army, audience, class, family, team, crowd, staff, government, enemy, committee等。有些集体名词如cattle, people, police等,通常看作复数，谓语动词必须用复数形式。如：
The audience was / were clearly delighted with the performance.
The police are also looking for a second car.
(2) 单复数同形的名词作主语时，应根据其意义来决定谓语动词的形式。如：
The only means of communication I could use was sign language.
Various means have been employed to ensure the stability of these roadways.
(3) 表示单数概念的复形名词（如学科、机构、书名、剧名、国名等）作主语时，谓语动词通常用单数形式。如：
Today, physics is a broad and highly developed subject.
(4) trousers, shoes, chopsticks, sunglasses等名词作主语时，谓语
动词通常用复数形式；但如果其前有a pair of, a kind of等时，谓语动词一般用单数形式。如：
Sunglasses are / A pair of sunglasses is a necessity whether you're camping, climbing or cycling.
(5) 当名词短语的中心词为表示距离、金额、时间等的复数名词时，往往把这些复数名词看作一个整体，谓语动词用单数形式。如：
I believe twenty pounds is enough to buy a present.
(6)“more than one / many a +单数名词”作主语时，谓语动词通常用单数形式；“more +复数名词+ than one”作主语时，谓语动词通常用复数形式。如：
Many a mother tries to act out her unrealized dreams through her daughter.
More students than one have attended the class.
(7) “分数或百分数+ of +名词”构成的短语作主语时，谓语动词的单复数取决于of后名词的数。如：
Two-thirds of the people present are in favour of the plan.
In a flat, 60 percent of the area is occupied by bedrooms.
2. 代词作主语
(1) 代词each, either, neither, another以及复合不定代词作主语时，谓语动词通常用单数形式。如：
You need to believe anything is possible and have the winning mentality.
(2) 关系代词who, that, which在定语从句中作主语时，谓语动词的数应与先行词的数一致。如：
Such a policy might benefit teenagers, who are often so busy with after-school activities.
(3) all, most, none, some等作主语时，谓语动词的形式要根据它们所代替的内容来定。如：
Some say it was an accident, but I don't believe it.
3. 并列结构作主语
(1) 由and连接的名词作主语时，谓语动词通常用复数形式。但当and连接两个在意义上表示同一人、物、概念或由两个部件配成的物品时，谓语动词则用单数形式。如：
Fish and chips is a kind of meal that originally came from the United Kingdom.
(2) 当主语后跟有说明主语的修饰语，如由with, but, as well as, along with, rather than, together with, including, in addition to等引导的短语时，谓语动词的数与主语保持一致。如：
Professor Smith, along with his assistants, is working on the project day and night.
(3) 由or, either ... or ..., neither ... nor ..., not only ... but also ...等连接的名词或代词作主语时，谓语动词的数通常要与邻近的主语相一致。如：
Not only I but also my sister goes rock climbing often.
4. 从句及非谓语动词作主语
(1) 名词性从句作主语时，谓语动词通常用单数形式。但如果是两个或两个以上的从句由and连接表示两个概念时，谓语动词用复数形式。另外，what从句作主语时，谓语动词的数由其表示的意义来决定。如：
What caused the accident and who was responsible for it remain unknown.
What they intend to do is to make you joyful.
(2) 动词-ing形式短语或不定式短语作主语时，谓语动词通常用单数形式。如：
Improving the production process is necessary.
To know merely the main facts is not enough.
1 If anybody has/have any tips for memorising information, I would like to hear them.
2 Many experts says/say that you should review information periodically after you learn it.
3 Each of the students is/are trying one of these memorising techniques this week.
4 Both of my English teachers tells/tell me to ask questions to identify the most important information I need to remember.
