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。
