4 时态的定义： 各位学员： 视频观看结束，想必大家对英语时态已经有了初步的了解，现在就让我们来系统学习！
英语中不同时间发生的动作或存在的状态要用不同的动词形式来表示。由于动作发生的时间不同，动词的形式就有所不同。 　 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。 时态的定义：

5 表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用；也表示过去经常或反复发生的动作，常和表示频度的时间状语连用。
过去时

6 一般过去时态（The Simple Past Tense)介绍
1.用法：表示过去某个时间发生的动作或存在的状态；表示过去经常或反复发生的动作。 2.时间状语： yesterday ,last night, this morning, in 1990 ,just now, two days ago 等。 3.频度副词:often, usually, always,hardly ever 等 eg: I often played it in 1990.

7 巧记动词过去时态 动词一般过去时，表示过去发生事； be用was或用were, have,has变had； 谓语动词过去式，过去时间作标志；
一般动词加-ed，若是特殊得硬记。 否定句式很简单，主语之后didn’t添； 疑问句式也不难，did放在主语前； 谓语之前有did，谓语动词需还原； 动词若是was,were, 否定就把not添。
