1、一般过去时语法知识一般过去时表示过去某个时间发生的动作或状态；过去习惯性、经常性的动作、行为；主语在过去时间段所具备的能力和性格。一般过去时句子最明显的现象就是常由表达过去时间的副词、副词短语或从句来界定。“过去”的概念并不仅指如“yesterday, last week, ”等，实际上“与现在对立的过去”，亦即“非现在的以前”，哪怕是“过了说话时间的几分钟之前”，只要所要表达的时间与说话时的“现在”形成对立，就必须使用一般过去时来表达。例如：He was here only a few minutes ago.仅仅几分钟前他还在这里。I came home just now. 我刚回到家。“
2、this + 时间，today”等时间副词常用于修饰一般现在时，但是只要句子的本意是“与说话时的现在”对立，即使句子中有“this + 时间，today”等时间副词，也必须使用一般过去时。例如：I got up very early this morning.今天早晨我起床很早。He was late for school again today.今天他又迟到了。强化理解：1.一般过去时表示在过去某个特定时刻或时期所发生的事情，也可以表示过去习惯性、经常性的动作。一般过去时只说明过去的事情，不强调动作对现在的影响。I had a word with Julia this morning.今天早

4、y opened his eyes for a moment, looked at the captain, and then died.那男孩把眼睛张开了一会儿，看看船长，然后就去世了。4.有些句子虽然没有表示过去的时间状语，但实际上发生的动作或存在的状态是指过去，也要用一般过去时。这一点我们中国学生往往出错，要特别注意！I didnt know you were in Paris.我不知道你在巴黎。(因为在说话时，我已经知道你在巴黎了。这句话指的是说话之前，所以只能 用过去时表示。实际上，这句话暗指：But now I know you were here.)I thought you w
