系动词Be(am, is, are)的用法
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。
