1。谓语和谓语基本保持单复数的一致,即：主语是可数名词单数或不可数名词时,谓语动词用单数形式：如：The computer was a great invention。(计算机是个了不起的发明)The water in the glass is very cold。
(玻璃杯里的水很冷)
2。集体名词(如family, class, team, group, row, police, school等)做句子主语时,
① 如果表示整体概念,则谓语用单数形式,如：Class Three is a very good class。
(三班是好班)
② 如果表示其中的所有成员时,则谓语用复数形式,如：Class Three have a map of China。(三 班有张中国地图)
3。Chinese, Japanese, fish, sheep, people等表示单个时谓语用单数,表示许多时,谓语用复数。
如：There is a sheep in the yard。(院子里有只绵羊) / There are some sheep in the yard。(院子里有一些绵羊)
4。maths, news等虽然有s结尾,但不是复数,因此谓语仍用单数：The news is very exciting。
(这个消息令人兴奋)
5。glasses, shoes, socks, trousers, gloves等名词往往用复数形式,故谓语用复数。如：
The trousers are very cheap and I want to take them。
(裤子很便宜,我想买)
6。a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式。如：A lot of students are playing baseball now。(现在有许多学生在打垒球) A lot of time was wasted on that work。
(大量的时间花在了那个工作上)(被动句)
7。and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数。如：The teacher and his son are picking apples now。
(老师和他的儿子在摘苹果) / Fish and chips is very famous food。 (鱼和薯条是一种出名的食品)
8。 there be 句型中be的单复数一般由靠近的名词决定。如：There is a table and four chairs in the room。
(房间里有一张桌子和四张椅子)
9。用both…and…连接两个事物做主语时,谓语一般用复数。如：Both you and I are required to be here tomorrow。(你和我明天要求都来)
10。主语中含有with的短语时,谓语单复数由with之前的人物决定。
如：A woman with a 7-year-old child was standing at the side of the road。 (一名妇女带着一个七岁的孩子(当时)就站在路边)。
