主谓一致原则 (Subject-Verb Agreement)
主谓一致是指谓语动词与主语在人称和数上保持一致，即主语的单复数决定谓语动词的单复数。
一般来说，语法形式或意义上是单数的主语，谓语动词用单数形式；语法形式或意义上是复数的主语，谓语动词用复数形式。
语法形式或意义是单数的主语，例如：
The girl ges t schl by subway.
Mr Li teaches us Chinese.
The cat sleeps n the bed.
Mr Smith cmes frm the US.
语法形式或意义是复数的主语，例如：
We lve ur cuntry.
The birds fly ver the tree.
The students study very hard.
My parents walk every mrning.
谓语动词的复数形式一般用动词原形来表示。
谓语动词单数形式的书写规则
wrks, writes, wants
以ch, sh, s, x或结尾的词加es
watches, teaches, pushes
动词辅音+y结尾，变y为i加es
flies, cries, studies
助动词have的第三人称单数形式是has
be动词的单数形式，在一般现在时和现在进行时中是is，过去时中是was
当主语为I时，be动词为am，过去时为was

助动词通常辅助主要动词表现时态、语态以及变成否定、疑问句结构等，它不能离开主要动词单独使用。
