SAT主谓一致放心头
 

nobody doing 谓单数

both and 连接谓复数

C替换A+B莫单数

介、分插名词就远走

选择性therebe就近守

倒装结构就后搂一搂

这些原则说顺口

主谓一致你最牛

一句一句解释咯：

nobody doing 谓单数——也就是主单谓单原则

①单数可数名词(主)à单(谓)

e.g.1 A book is on the desk.

②不可数名词 (主)à单(谓)

e.g.2 Water is colorless.

③doing (主)à单(谓)

e.g.3 Seeing is believing.

④不定代词 (主)à单(谓)

e.g.4 Nobody knows his name.

both and 连接谓复数——也就是主复谓复原则

①可数名词复数(主)à复(谓)

e.g.1 Two books are on the desk.

②A and B (主)à复(谓)

e.g.2 Pears and apples are fruits.

③both A and B (主)à复(谓)

e.g.3 Both Lucy and Lily are girls.

C替换A+B莫单数——也就是名词数的一致性

The convenience and widespread

availability of watercolor paint

are (a reason/reasons) for its popularity with amateur artists.

n1+n2 不是 a/an + n(单)

介、分插名词就远走——就远原则的两种情况

N1+修饰成分+N2+谓动

修辞成分是介词和分词

选择性therebe就近守——就近原则的两种情况

①not only N1 but also N2+谓动

not N1 but N2 +谓动

neither N1 nor N2+谓动

either N1 or N2+谓动

②There be +N1

There be +N1 and N2

倒装结构就后搂一搂——就后原则

比如only，形容词，介词，done放开头的是SAT最常考的
