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。 相关练习题 一、用 am, is, are 填空 1.
