语法归类 1 西大英语班

NAME:

一、在肯定句中，缩写一般是把be动词首字母换成’

I am=I’m he is=he's she is=she’s it is=it’s

l et us= Let’s t hat is=that’s we are=we’re they are=the y're what is= what’s who is=who’s where is= where’s

注：this is 和 am not 没有缩写

二、否定句的缩写形式。

否定句一般加not,只要把not中的o换成’就好了

三、be动词的用法口诀：

♦我用am, 你用are, is用在他她它，复数全用are。我（I）是am ,你(you)是are, ♦is连着他（he）、（她）she、（它） it；

♦单数名词用is, 复数名词全用are.

♦变疑问，很简单，be需大写来提前，

♦变否定，更轻松，be后not记心中。
