二者时态不同,is是一般现在时态,was是过去时态。二者用法不同,“现在时间”用is,“过去时间”用was。be动词的形式有am,is,are,been,being,was,were。这里高考家长网为大家分享了《was和is的区别》,希望在was方面对您有一定的参考价值。

be动词

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

“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)

例句对照

当做主动词时,“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如:

The man is a science teacher.

这个男子是一位科学教师。

Mary's new dresses are colourful.

玛丽的新衣服色彩鲜艳。

I have been there before.

我以前去过那里。

My mother is in the kitchen now.

我妈妈现在在厨房里。

这四个都是陈述句,可以变成疑问句,方法简单,把主语和“be”或助动词对换位置即可:

Is the man a science teacher?

Are Mary's new dresses colourful?

Have I been there before?

Is mother in the kitchen now?
