英语be动词有哪些 be动词是助动词吗

be动词是英语动词比较特殊的一类动词，那么，英语be动词有哪些呢？下面小编整理了一些相关信息，供大家参考！

形式

有不同的be动词，基本上为：

am,is,are,was,were,been,being,be

用法

be（be/is/are/am/was/were) [bi:] vi

he is, we are, you are, they are （缩略式 I'm, you're, he's, we're, you're, they're）, （否定缩略式 I'm not, isn't, aren't）, 过去时 I was, you were, he was, we were, you were, they were （过去时否定缩略式 wasn't, weren't）,过去分词been,现在分词being

英语的“be”是个特殊动词；有些语言，如马来文等，并没有“be”这样的动词。

“Be”除了原形的“be”之外，还有另外七种形式：am, is, are, been, being, was, were.

在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)

它们有本质区别。be动词，既可以是联系动词，也可以是助动词。

联系动词，后接名词、非谓语动词、形容词、数词、代词、副词、介词等作表语，且有各种时态变化：

一般现在时amisre

一般过去时waswerer

完成时hashavehadeen

将来时用be原形

现在分词being

过去分词been
