was和is的区别

时间:2020-09-19 00:35:49

  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动词

  be(be/is/are/am/was/were)[bi:]vi

  he is, we are, you are, they are (缩略式 Im, youre, hes, were, youre, theyre), (否定缩略式 Im not, isnt, arent), 过去时 I was, you were, he was, we were, you were, they were (过去时否定缩略式 wasnt, werent),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。

  Marys 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 Marys new dresses colourful?

  Have I been there before?

  Is mother in the kitchen now?
