所谓主谓一致是指“主语和谓语动词”之间,即主语的人称和单复数形式决定着谓语动词对应的形式。
2.1 语法一致
<and连接>两个或两个以上单数名词或者代词作主语的时候,谓语动词有以下两种情况:
(1) 如果指两个或两个以上不同的人或事物的时候,谓语动词用复数。
He and she are both students of this school.
他和她都是这个学校的学生。
(2)如果连接两个以上的名词指的是同一个人或物, 或者指同一概念的时候, 谓语要用单数。
The singer and dancer is going to give us a performance.
那个歌唱家兼舞蹈演员要给我们表演。
如果主语是<不定式, 动词ing形式或主语从句>的时候,谓语动词一般用单数。
When he is coming seems very important.
他什么时候要来看起来很重要。
Collecting stamps is his hobby.
收集邮票是他的爱好。
定语从句的<关系代词who, which, that>在从句中作主语时,要与<先行词>的人称和数保持一致。
Tom, who is your friend, should help you.
汤姆,你的朋友,应该帮助你。
with, along with, together with, as well as, besides, like, without, except, but, including 如果句子中有这些连接词和主语连用,谓语动词的数<随主语的变化>而变化。
例如:
The teacher, together with his students, is planting trees in the street.
老师和他的学生们正在街道上植树。
2.2 意义一致
指主谓一致取决于主语的其实际意义。(有的主语名词在形式上是单数, 但在意义上却是复数;有的主语名词在形式上是复数, 但在意义上却是单数。)
