and连接并列的两个或两个以上的人或物作主语,表示单数意义,谓语动词用单数;表示复数意义,谓语动词则用复数。eg, 1.Ham and eggs is a good breakfast. (ham and eggs 固定搭档,已成为一种食物) 2.The secretary and treasurer is abent.(the secretary 和 treasurer指的是同一个人,因为只有一个the) 3.The singer and the dancer are good friends.(当and连接的主语分别带有the时,指的是不同的人)
例句:
My parents often tell me that going to bed early and getting up early is a good habit. 我的父母经常告诉我说,早睡早起是一个好习惯。
解析:
Going to bed early and getting up early 作主语时,谓语动词应该用单数,因为,虽然它是两个动名词的并列,但它指的是一个概念,而不是指两个概念——即“早睡早起”是一个好习惯,而不是分开指“早睡”是一个好习惯,“早起”是一个好习惯。
The fork and knife is on the desk.那副刀叉在桌上。
The teacher and doctor is my father.那位老师兼医生是我爸。
Knife and fork is what we need when we have a meal.
