主谓一致原则分类

语法一致

谓语动词与主语单复数保持一致

• Time（单数名词） is money.
• Carrots （复数名词）are delicious.

• A number of carrots have been eaten.
• A lot of carrot juice has been sold.

• To eat a carrot ever day is good for the rabbit.
• Eating carrots is healthy.

• The rabbit and the wolf are at the party.

假像主语

• The rabbit as well as other animals gets a carrot.

as well as other animals 其实可以视作对the rabbit的补充信息，所以真正的主语可以理解为the rabbit

• All the animals except the wolf get the carrots.

同上

不定代词作主语

• Everyone gets a carrot.
• Each of them gets a carrot.

• Both of them like carrots.
• Some of them are afraid of the wolf.

• None of them get/gets a carrot.
• Neither of them is/are afraid of the wolf.

“没有”比较特殊，不能数数，那就干脆单复数动词都行。

意义一致

同一个主语多种身份

The teacher and video creator is a rabbit. 在这里，主语是一只兔子，只不过有双重身份，老师和视频创作者。也就是主语的意义是单数，所以谓语动词用单数，这也就是前面提到的“不要一看到and，就直接用复数谓语动词”

The teacher and the video creator are rabbits. 这样主语的意义就变成了两只兔子，一个老师和一个视频创作者

复数名词的单数意义

Ten years is a long time.

• A knife and fork is needed for eating the carrot. 一副刀叉，是一个整体概念
• Bread and butter is also needed at dinner. 面包和黄油也是晚饭所必需的。

不定代词的单复数意义

• All is quiet. 一切都很安静，这里的All是个抽象的概念，相当于Everything
• All are quiet. 大家都很安静，这里的All指大家，代表很多人

名词的形和意

• 形复意单

Physics is my favorite subject.

• 形单意复

The cattle are on the hill.

• 单复数同形名词（看主语代表的是单数还是复数意义）

A sheep is eating grass. 一只绵羊 / The sheep are eating grass. 一群绵羊

类似的名词还有：deer，means，series，species n.物种 等

• 集合名词（即可代表一个集合也可以代表集合中的全部成员，看其代表的意义是单数还是复数）

The rabbit’s family is huge. 家庭这个整体概念 / The rabbit’s family are all at home. 全部家庭成员

类似的名词还有army，audience，police，team等。

All the furniture here is expensive. 家具在这里是一个集合

the + 形容词 作名词主语，也可以视作集合名词，可表单数意义，也可表复数意义，比如：

• The young are expected to learn from the old. 年轻人应该向老人学习
• The new is going to replace the old. 新事物会取代旧事物

就近一致

or, either…or…等

• or…

• either…or…

Either you or I am going to the park.

be going to 不是将要去…，为什么是be going to the park而不是be going to go to the park

英语中的一些趋向动词如go,come,leave,arrive等,其进行时常表示计划、安排好的行为,故I’m going to the park.就可以表示“我将去公园”之意.此外,根据上下文I’m going to the park.也可以表示“我正去公园”之意.如在下面的对话中：

A:Where are you going now?

B:I’m going to the park.

I’m going to go to the park.的说法显得很幼稚,不好.

• neither…nor…

• not only…but also…

Not only the rabbit but also many other animals like carrots.

there be

There is a carrot and two apples on the table.
