主谓一致主要有以下几种情况:
1. 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) He and she _____both students of this school. 他和她都是这个学校的学生。
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。
一、语法一致原则
are
(2) 但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____ going to give us a performance.
那个歌唱家兼舞蹈演员要给我们表演。
The knife and fork ____on the table.

2. 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。
