was和is的区别
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。
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?
