要点1：掌握语法：一般过去时和be动词的过去式变化

       一般过去时含义：表达过去某个时间或一段时间内发生的动作或者存在的状态。

       be 动词有三种形式：am ，is，are ，表达的是一般现在时

       be动词的用法口诀是：我用am，你用are，is连着三个ta，单数用is，复数用are.

       be动词的一般过去式主要是was和were

       am和is 的过去式是was，

       are的过去式是were

       be动词过去式使用口诀：

       was连着she，he，it，单数was，复数were 

       be动词的否定式

am+not，  

is+not      =isn’t

are+not     =aren’t

was+not    =wasn’t

were+not   =weren’t
