主谓一致的语法
一、最基本的"主谓一致"规则
初中课本中最基本的"主谓一致"规则是:"单则单,复则复",即主语为单数时,谓语动词也用相应的单数形式;主语为复数时,谓语动词也用相应的复数形式。例如:I am a teacher. We are teachers. 但要注意:当表示时间、长度、距离、金钱、度量等词组作主语时,常将其看作是一个整体,谓语动词要用单数形式。例如:Two years is quite a long time. Ten dollars is enough.另外,加减乘除也常当作整体对待,谓语动词也用单数形式。例如:Forty-one plus fifty-nine is one hundred. How much isninety-nine minus sixty-two?
二、集体名词作主语时,谓语动词的使用
family, class, team等集体名词作主语时,若指一个整体,谓语动词用单数形式;但若指其成员时,谓语动词用复数形式。例如:The family is very big. Their family arewatching TV now.
三、neither... nor..., either...or..., not...but...,not only... but also...等连词连接两个名词(或代词)作主语时,谓语动词要与靠近它的主语一致。例如:Neither he nor I know anything about it. Notonly the students but also the teacher has visited the museum. there be…结构也属于此类。例如:There is a teacher,a desk, a blackboard, some desks andsome chairs in the classroom.但要注意:both…and…表示"……和……都",谓语动词一般用复数形式。例如:Both his father and mother are doctors.
四、两个主语用and连接时,谓语动词的使用
and连接两个名词(或代词)作主语时,谓语动词一般用复数形式。例如:Mary and Helen are good friends.但要注意:and连接的两个名词只表示一个概念时,谓语动词要用单数形式。例如:A singer and dancer is coming.一个歌手兼舞蹈家就要来了。
五、politics, physics, works, the United States,news, maths等词作主语时,谓语动词的使用
这类形式上为复数,意义上却是单数的名词作主语时,谓语动词用单数形式。例如:The news is very exciting. Physics is a bitdifficult for me.但要注意有些名词,如:people(人;人们),police等则是形式为单数,意义是复数,谓语动词要用复数形式。例如:People there are very friendly
六、不定代词作主语时,谓语动词的使用
1.something, everything, anything, nothing,everybody, anybody, nobody, everyone, anyone等复合不定代词,以及either,neither(neither of), each (each of), each one, no one, another等代词作主语时,谓语动词用单数形式。例如:Neither of the answers is right. Somethingis wrong with my computer.
2. both, few, a few, many, several, others作主语,或它们所修饰的名词作主语时,谓语动词要用复数形式。例如:A few people can live to 100, but few canlive to 150. Both of them are in my class.
七、with, as well as, like等修饰的单数名词作主语,谓语动词的使用
单数名词作主语,且后面有with, as well as, like等修饰时,谓语动词用单数形式。例如:1.The teacher with his students has gone to the library. 2.Is the womanlike you your mother? 3.The instrument as well as other spare parts is going tobe airlifted soon. (该仪器以及其它一些备用件不久将空运。)
八、动词不定式(或动词不定式短语),V-ing形式以及名词性从句作主语,谓语动词的使用
动词不定式(或动词不定式短语),V-ing形式以及名词性从句作主语,谓语动词用单数形式。例如:1.To eat in a fast food restaurant is cheapand saves time. 2.Climbing hills is good exercise. 3.What interests the workersmost is better wages and workingconditions. (工人们最关注的是好的工资待遇和工作条件。

主语第三人称单数是指he she it 以及所有的单数可数名词和不可数名词,都算作第三人称单数。
谓语的复数概念是指不用加s的形式,也就是常讲的原型形式(be除外)。
he needs a book.三单主语+单数谓语形式
she needs a book.三单主语+单数谓语形式
i need a book.第一人称单数+非三单谓语形式
you need a book.第二人称单数+非三单谓语形式
we need books.第一人称复数主语+非三单谓语形式,也就是你说的谓语复数形式
追问你说主语第三人称单数是指he she it 以及所有的单数可数名词和不可数名词,都算作第三人称单数。那非谓语动词和名词性从句等做主语呢?
追答也看做第三人称单数
