二、常搭配的时间状语：ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc.三、基本结构：①be动词的过去式（was/were）；②行为动词的过去式（即在动词原形后加ed，不规则变化的动词除外）否定形式：①was/were+not;②在行为动词前加didn't，同时还原行为动词。

一般过去时用谓语动词的过去式构成，即在动词原形后加ed，不规则变化的特殊动词除外。
例句：He was here just now. 他刚才还在这里。
What did you do yesterday? 你昨天做了什么事？We often played together when we were children. 我们小时候常在一起玩。
He used to smoke a lot, but he doesn’t no w. 他过去经常抽烟，但现在不抽了。
四、基本用法主要是用来描述在过去某个时候发生的动作或存在的状态。
它也可以用来表示在过去某段时间里经常发生的习惯性动作。
这一点在表达意义上与一般现在时相同，只是所在的时间区域不同而已。
由于它的主要作用如此，所以在使用一般过去时的句子里常常有一个意义较具体的过去时间状语。
这也是它与现在完成时的最大区别之一。
常和一般过去时连用的过去时间状语有：last night (week ,month , year , century ,etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hou rs ago ( one week ago , tree years ago , …)等等。
使用一般过去时，在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。
"过去"的时间概念有两层意思：一是指"现在某个时间"以前的时间；二是指"说话、写文章的那个时间点"以前的时间，在这个意义上，"现在的那个时间点"是很小很小的，甚至于小到无法量化的程度。
例如：He got his driving license last month. 他上个月拿到了驾照。
--Where's Jim? 吉姆在哪里？--He just went out.他刚刚出去。
