was的用法是什么?
was 是am is 过去式 ;were 是are 过去式 .
具体用法如下:
1.was用于 I ,he ,she,it 以及 单个人作主语的句子.
例如:
I was born in 1998.
He was a doctor three years ago.
She was at home yesterday.
It was Monday yesterday.
Mike wasn't at home this morning.
2.were用于you,they,we 以及两个以上的人作主语的句子.
例如:
You were at home yesterday.
They were at the playground an hour ago.
We were singing in the room an hour ago.

was是英文单词am(vi.是; v.aux.; abbr.)的第三人称单数过去式,同时也是多个英文词组的简称。
因为 be 动词am对应的过去式是was
当你要表述过去发生的事情的时候,要把时态改一下,
而且改了之后注意其他动词的时态,也应该是过去时

was 是am is 过去式were 是are 过去式
