小学英语be动词用法及练习

语法2班暑假作业
一、在肯定句中一般把首字母换成’
I am=I’m he is=he's they are=they're she is=she’s
we are=we’re it is=it’s Let us= Let’s That is=that’s
what is= what’s who is=who’s where is=where’s
注：This is am not 没有缩写
二、否定句的简写，
否定句一般加not,只要把not中的o换成’就好了
isn’t = is not aren’t = are not can’t = can not
don’t = do not doesn’t = does not
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；
♦单不可数用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。
