　　一般过去时的用法：

　　1.过去某个特定时间发生，并且一下子就完成了的动作(即：非持续性动作)，也可以表示过去习惯性的动作。一般过去时不强调动作对现在的影响，只说明过去。

　　I had a word with Julia this morning. 今天早晨，我跟朱丽亚说了几句话。

　　He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子，烟抽得可凶了。 一般过去时常与表示过去的时间状语或从句连用，过去时间状语如：yesterday, two days ago…(两天前)the other day(前几天)，last week / year, in 1993, just now(刚才)、in the old days(过去的日子里) at that time, once, during the war, before, a few days ago, when引导的时间状语从句等。

　　句子中谓语动词是用一般过去时还是用现在完成时，取决于动作是否对现在有影响。如果句中带有确定的时间，只能用一般过去时，不用现在完成时。

　　Have you had your lunch? 你吃过午饭了吗?(意思是说你现在不饿吗?)

　　Yes, I have. 是的，我已经吃过了。(意思是说已经吃饱了，不想再吃了。)

　　When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)

　　I had it about ten minutes ago. 我是大约十分钟以前吃的。

　　2.一般过去时谓语动词的构成：

　　(1)be(was, were)作谓语. 否定句是在was/were后面加not，was not(wasn't) / were not (weren't)。一般疑问句是把was / were提前并放到句首，首字母要大写。

　　肯定句: She was at home yesterday.

　　否定句: She wasn’t at home yesterday.

　　一般疑问句: Was she at home yesterday?
