一、主谓一致
1. 主谓的分隔原则
S, ---,VO
主谓之间可以用定从及省略形式的定从分隔
* 主谓一致与主语同位语无关
2. 定语从句中的主谓一致
...noun.+that/which+V
* that, which并不反映单复数
one of 复n + that/which + 复V
the only one of 复n + that/which + 单V
3. 随前一致
together with, as well as, with, including, of
4. 随后一致
not 单n. but 复n. + 复V
not noly 单n. but also 复n. + 复V
5. 就近一致
单n. or 复n.
either 单n. or 复n.
neither 单n. nor 复n.

he or we are... 对
6. 可数名词and可数名词+复数动词
不可数名词and不可数名词+复数动词

7. 百分比结构
most, rest, half, majority, some, 50 percent, one percent
__+of+n.+V 由名词决定动词的单复数
8. 倒装句中的主谓一致
There be...
between , among 等介词位于句首，即引起倒装
Between ...+ be + noun.
Among...+ be + noun.
主 + 系 + 表
主系关系要一致，系表关系可以不一致
9. The+ adj.
a. 表示“一类人”用复数V
The rich are ridiculous

The good is attractive
10. one of + 复数noun. + 单V
more than one 单数noun. + 单数V
