主谓一致
所谓“主谓一致”是指英语句子中主语和谓语在数、人称方面一致。一般说来，当主语是复数名词时，谓语动词用复数形式；当主语是单数名词或者不可数名词时，谓语动词用单数形式。如：Li Ming is a good student. We study English hard.
但在很多情况下，主谓一致存在一些特殊情况，现归纳如下：小米是什么系统
一．语法一致原则
1. 主语是从句，非谓语动词（即动词不定式、动名词和分词）和不可数名词时，谓语动词用单数。但what 从句作主语时，谓语动词一般根据表语决定。
Eg: What he needs are two books. What I’m worried about is your safety. To e is to believe.
2. and 连接两个单数名词时
(1)两个单数名词表示不同的概念时，谓语动词用复数。
Eg: Steam and ice are different forms of water.
(2)如果表示的是同一个人、同一件事或同一概念时，谓语动词用单数。
Eg: The singer and dancer is to attend our party.
悄无声息是什么意思
Only a knife and fork is left on the table.
Truth and honesty is the best policy.
(3)在both …and …结构中用谓语动词用复数。
Eg: Both Tom and I are fond of English.
(4)名词前有no, each, every, many a, not a, more than one修饰时，谓语动词用单数。但more +复数名词+than one,谓语多用复数。
Eg: Many an adult and many a child has en it.
Each hour and each minute is important.
More than one student has failed the exam.
(5)不可数名词由and 连接的两个并列形容词来修饰时，谓语动词用复数。
Eg: Good and bad meat in the supermarket are sold out.
试比较：Beer from the United States and Germany is much better.
(6)and 连接两个并列从句时，谓语动词用复数。
Eg: What he says and what he thinks have nothing to do with me.
试比较：Where and when to hold the meeting has not been decided.
(7) and作“加”解，谓语多用单数。Eg: Two and three is five.
3. 不定代词作主语时，谓语动词用单数。但应注意，不定代词each作同位语时，不影响谓语动词的数。
Eg: Each of them has the right to do it.
The girls each have a new hat.
4. some, any ,all,none,half,part,more,most,the rest, a lot of, lots of, plenty of, percent of,分数等后面接复数名词作主语，谓语用复数（none也可用单数）；后接单数名词或者不可数名词做主语，谓语用单数。
Eg: Half of the workers here are under twenty.
Ninety percent of the work has been done.

Eg: One out of ten was saved in this accident,

6. “the + 复数姓氏”作主语，谓语用复数。Eg: The turners are at tables.
7. 由两部分构成的表示物体的名词，如trours, pants, jeans, compass, glass, shorts等作主语时，谓语动词用复数。但如果这类名词前用了a pair of 或 two/three/… pairs of 来修饰，谓语动词在数上要与pair保持一致。
Eg: The trours need cleaning. This pair of trours is mine.
同样的，主语前有表示“时间，距离，价格，单位，度量”等的短语kind,sort,type,form,pair,suit,cup,glass,piece,load,block,box,handful,quantity,ton,meter of…等时，谓语与该“时间，距离，价格，单位，度量”词本身的单复数形式一致。
8. a… or two 大多数用单数谓语；one or two … 用复数谓语
我的爱在我身边Eg: One or two shirts are enough for the trip. Only a word or two is needed.
亚洲卫视9.主语后接with, together with, along with, more than, rather than, no less than, as well as, as much as, but, except, not, besides, like, including, added to, in addition to等短语时，谓语和这类短语前的主语一致。
Eg: He rather than you is to blame.
No one but we knows the cret.
10. 关系代词在定语从句中作主语时，定语从句的谓语动词由先行词决定。应特别注意：“one of +复数名词”后的定语从句谓语用复数，而“the / the very /the only one of +复数名词”后的定语从句谓语用单数。
