系动词 Be(am, is, are)的用法一、请记住以下口诀:我用 am,你用 are,is 连着他,她,它;单数名词用 is,复数名词全用are
变疑问,往前提,句末问号莫丢弃
变否定,更容易, be 后 not 莫忘记
疑问否定任你变,句首大写莫迟疑
二、 Be 动词在一般过去时中的变化:1.am 和 is 在一般过去时中变为was
( was not = wasn’t)2.are在一般过去时中变为were
( were not = weren’t)3.带有 was 或 were 的句子,其否定、疑问的变化和am,is, are一样,即否定句在was 或 were 后加 not,一般疑问句把was 或were 调到句首
