谓语动词与主语必须在人称和数上保持一致,这叫做主谓一致。主谓一致的应用主要有以下几种情况:1.集体名词作主语,如果指整体概念,谓语动词用单数形式;如果指具体成员,谓语动词用复数形式。常见的这类名词有:army,audience,class,crowd,crew,family,group,government,population,staff,team,public等。

The population of the earth is increasing very fast.地球上的人口在迅速增长。One third of the population here are workers.这里的人口中有三分之一是工人。The team is well organized.这个队组织得很好。The team are all good players.这个队的队员都是好样的。
2.有些有生命的集体名词如people,cattle,police,mankind,folk等作主语时,谓语动词只用复数形式。The police have not made any arrests.警方没有进行搜捕。The mankind long for peace.人类希望和平。[温馨提示]people表示“民族”时有单复数形式,但表示“人,人民”时为复数意义,不可加s。
3.单复数同形的名词作主语时,谓语形式要根据句义来确定。常见的这类名词有:deer,fish,sheep,species,series,means,aircraft,crossroads,headquarters等。Every means has been tried.每种方法都试过了。The means of communication between here and outside are interrupted.这里同外界的通信工具都中断了。
4.一些常用作复数或只有复数形式的名词作主语时,谓语动词用复数形式。常见的这类名词有:clothes,trousers,shorts,goods,arms,compasses,jeans,stockings,gloves,surroundings,thanks等。His clothes are hanging on the back of the chair.他的衣服挂在椅子背上。The house itself is beautiful,but the surroundings are rather unpleasant.房子本身挺漂亮,只是环境欠佳。
[温馨提示]若表示成双的东西的名词前面有数量词pair时,要根据pair的单复数来确定谓语动词用单数还是复数形式。The scissors are on the ground.这把剪刀在地上。This pair of scissors belongs to the tailor.这把剪刀是裁缝的。
5.表示时间、距离、价格、度量衡等的复数名词或短语作为一个整体看待时,谓语动词一般用单数形式。Four thousand dollars is more than she can afford.她付不起4 000美元。Three days is too short a time for me to do it.三天时间要我做成这件事太短了。但若强调这类词组的复数意义,谓语动词也可用复数形式。Two hundred tons of water were used last month.上个月用了200吨水。
6.用作书名、剧名、报纸名、国名、组织机构等的复数名词作主语时,谓语动词用单数形式;但如果是山脉、群岛、瀑布等的名称,谓语动词用复数形式。The New York Times still has a wide circulation.《纽约时报》的发行量仍然很大。The United Nations is an international organization.联合国是一个世界性的组织。The Great Lakes lie between the US and Canada.五大湖位于美国和加拿大之间。
