1．主谓一致（与插入语无关）

1主谓的分隔原则：主谓之间可以用定语从句或者省略的定语从句分隔。

2定语从句中的主谓一致：

3随前一致：

n.+together with　n2

as well as

including

along with

with/of

accompanied with/by

4就近原则：n1 or n2+v（就近原则）

either n1 or n2

5可数n1 and可数n2+v(pl)

不可数n1 and不可数n2+v(pl)

例外：war and peace is…war and peace是一个整体

但是如果主语表示的是同一个概念，同一人，同一事的时候，谓语动词用单数，这种结构的特征是and连接的两个词只有一个冠词。

The iron and steel industry is very important to our country.

The head master and mathematical teacher is coming.

The head master and the mathematical teacher are coming.

类似的还有：law and order　bread and

butter　black and white

To love and to be loved is…

A lawyer and a teacher are…

A lawyer and teacher is…

6随后原则：not A but B/not only A but also B+v.(与B一致)

7百分比结构：most,half,rest,some,majority,one+persent

of+n1+v.（由n1决定）

8倒装结构的主谓一致：

a）There be+n由名词决定动词

b）Among,between等介词位于句首引起倒装结构：

Among/Between…+系动词+n.（由名词决定动词）

9The+adj的主谓一致：

a）当表示“一类人”，

b）当表示某一抽象概念时

The good is always attractive.

10 To do/doing/主从+vs

*More than one+n

many a+n.

a day or two
