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。

am, is, are的用法

1. is和are可分别与not缩写为isn’t和aren’t，但am却不能与not缩写为amn’t ，虽然有人把它缩为ain’t，但这毕竟是规范的口语说法，不宜仿用。

2. 陈述部分为第一称肯定式时的反意疑问句，通常用aren’t如：

I’m late, aren’t I?我迟到了，是吗？

3. 不要认为在主语之后总是用am。试看：

Both he and I are right. 他和我都对。或他和我都不对。 Neither he nor I am (或are) right. 他和我都不对. \"I\" is an English letter. I是英语字母。

4. 当am, is are 位于句末时，均不能与主语缩写。如： Tell me where he is (不能用he’s )。告诉我他在哪儿。 He is taller than I am (不能用I’m )。他比我高。 A：Are they watching TV? 他们在看电视吗？ B：Yes, they are. (不能用they’re)是的。

注：若其后有not时，am, is, are则可以与主语缩写，其中is和are 也可与not 缩写。如：

Are they watching TV? -No, they’re not (或they aren’t).
