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
