一般过去时语法总结

I was angry yesterday.We were busy yesterday. 

1、人称代词主格作主语 + was/were + 形容词作表语

主语是专用名词（单数概念）Nick was thin before.

主语是可数名词单数时his father was busy yesterday.The book was cheap before.

名词复数作主语his students were busy yesterday.computers were expensive before.

不可数名词作主语（单数概念）Oil was cheap before.The water was clean yesterday.

 名词单数用was，名词复数用were

2、名词作主语 + was/were + 形容词作表语。注意可数名词单数

You were a teacher before.She was a soldier before.

注意名词可数单数问题 添加限定词、也要注意逻辑问题。尽量使用表示人的名词作表语。

3、人称代词作主语 + was/were + 名词作表语。

主语名词单数的限定词和冠词。

4、名词作主语 + was/were + 名词作表语。

I was a teacher before.I was not a teacher before.

只需要在肯定句be（was/were）后面加一个否定词Not就可以了。

一般过去式变为否定句的规则

I was a teacher before.Were you a teacher before?

We were students before.Were you students before?

 只需要将be动词移动到句首，最后再添加问号?就可以了。但是有时候是需要根据实际情况，将主语的人称改变一下（人称换be也需要换），更符合逻辑。
