单元语法聚焦一

be动词(am, is, are)

在英语中，am，is，are统称为be动词。其中，am与I对应，可缩写为I'm；is对应he，she，it，可缩写为he's, she's, it's; are 用于第二人称you及表示复数概念的代词(如：we, they, she and I, these等)或复数名词(如：seven coats, many pencils)等之后。

记住并理解下面的顺口溜，你便掌握了be动词的用法： “我”用am，“你”用are, is连着“他、她、它”； 单数名词用is，复数名词都用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。
