否定句:主语+be动词的过去式(was,were)+not~.
疑问句:be 动词的过去式(Was,Were)+主语~?

1) be 动词过去时的肯定句

迈克去年在美国。
比较be动词的现在式和过去式:
主语 时态 现在时 过去时
I (第一人称单数) am was
He,She,It(第三人称单数) is
You(第三人称单、复数) are were

I was very tired last night.
我昨天晚上很累。
You were absent from school two days ago.
两天前你没到校(缺席)。

注意
There is(are)的句型用于一般过去时需把is,are变为它们的过去式:There was (were)….


2) be动词过去时的否定句

他去年不在加拿大。
be动词过去时的否定句的结构和现在时一样,只要在be动词过去式(was,were)后面加上not就可以了。否定式的was not,were not大多使用缩写形式wasn't(读作>&LQC)和weren't(读作V+:QC)

前几天我不忙。
There weren't any boys in the room.

be动词过去时一般疑问句的结构和一般现在时一样,只要把be动词的过去式was,were调到主语前面即可。Was(Were)+ 主语~?回答时,需用yes,was(were)。或No,…wasn't(weren't)。
注意
以疑问词开始的特殊疑问句,回答时,不能用Yes,No直接回答所问的问题即可。

否定句 He isn't ~. He wasn't~.
一般疑问句 Is he ~? Was he ~?
特殊疑问句 疑问句+Is he ~? 疑问词+Was he ~?
