大纲/内容
主系表结构
1、人称代词主格作主语 + was/were + 形容词作表语
I was angry yesterday.
We were busy yesterday.
We were busy yesterday.
2、名词作主语 + was/were + 形容词作表语。注意可数名词单数
名词单数用was，名词复数用were
主语是专用名词（单数概念）
Nick was thin before.
Nick was thin before.
主语是可数名词单数时
his father was busy yesterday.
The book was cheap before.
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.
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.
Oil was cheap before.
The water was clean yesterday.
3、人称代词作主语 + was/were + 名词作表语。
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。
You were a teacher before.
She was a soldier before.
She was a soldier before.
4、名词作主语 + was/were + 名词作表语。
主语名词单数的限定词和冠词。
The boss was an employee before.
They were a doctors before.
They were a doctors before.
一般过去式变为否定句的规则
只需要在肯定句be（was/were）后面加一个否定词Not就可以了。
I was a teacher before.I was not a teacher before.
You were great before.You were not great before.
一般过去式变为一般疑问句的规则
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。

I was a teacher before.
Were you a teacher before?
Were you a teacher before?
We were students before.
Were you students before?

一般过去时态的时间状语
一般情况下，一般过去时态是需要加上表示过去的时间状语。可以直接使用一些表示过去的副词
yesterday昨天、just now刚才、the day before yesterday前天、before以前
I was hunger just now.
大部分表示过去的时间状语，都是由介词或者副词跟其他词语构成的。
由副词ago(…前)构成，在ago前面加上表示时间的词语。
One/a/an + 表示时间名词的单数 + ago
One hour ago
数词(>2) + 表示名词时间的复数 + ago
Three days ago
I was busy three days ago.
I was busy three days ago.
由介词in(在) 构成
在 in 的后面加上一个表示过去年份的数词
In 2018 = 2018 年
I was young in 2018.
I was young in 2018.
由副词 last （上一个）后面加上表示时间的词语 Last + 表示时间的单数
Last hour、Last week、Last month、Last night、Last autumn
I was run last morning.
She was busy last week.
She was busy last week.
This/that + 表示时间的名词单数有时候也可以表达过去的时间概念
this可以今天的某个片段，that可以指之前某天
This morning. （现在已经不是早上了）
I was tired this morning.
This morning. （现在已经不是早上了）
I was tired this morning.
主谓宾结构
直接将谓语动词变化为过去式就可以了，但是如果主语为可数名词时，要注意名词的变化规则
人称代词主格 + 不及物动词过去式 + 过去的时间状语
I cried last morning.
We worked three days ago.
She ran this noon.
We worked three days ago.
She ran this noon.
名词 + 不及物动词过去式 + 过去的时间状语
My father slept last night.
The boy swam five hours ago.
The boy swam five hours ago.
人称代词主格 + 及物动词过去式 + 宾语 + 过去的时间状语
I bought the book last day.
You borrowed money yesterday.
You borrowed money yesterday.
名词 + 及物动词过去式 + 宾语 + 过去的时间状语
Your friend bought the book last day.
His friend broke his cellphone yesterday.
His friend broke his cellphone yesterday.
一般过去时的主谓宾变一般疑问句。
在句首加助动词did，并把动词变为原型，有时候需要根据逻辑需要把人称变一下。
I bought the book last day.
Did you buy the book last day?
Did you buy the book last day?
一般过去时的主谓宾变一般否定句。
在谓语动词前面加助动词did的否定式 did not，并且将谓语动词变为原型
I bought the book last day.
I did not buy the book last day.
I did not buy the book last day.
