2 开放英语1 课程介绍 开放英语1以日常生活用语为主，突出语言在实际生活中的运用。贯穿始终的主要语法有8种时态。 英语动词时态属于语法范畴,是表示动作或事态发生的时间以及表现方式的一种手段。动作发生的时间可分为现在、过去、将来及过去将来;动作的表现方式包括一般、进行、完成及完成进行。 在实际的语言交流中都需要运用时态来说明事情发生的时间，所以我设计本课件专门讲解时态的概念，构成，标志词以及具体如何运用。里面设计了大量的情境图片及练习题，并配备相应的Flash动画讲解。设计比较形象生动，内容充实，层次清晰，使用效果好，关键能使学生学有所获。

3 教 学 设 计 下面 我们开始学习吧！ 教学目的： 引导学生对8种时态进行初步的认识和运用。 教学重点： 教学难点：对完成时态的理解和运用。
教学理念：把英语时态简单化，规律化。 教学方法： 引导学生对8种时态进行初步的认识和运用。 时态含义，动词结构，时间标志和人称 变化。 教师引导讲解与学生自主，探究学习相 结合。 下面 我们开始学习吧！

5 时态的定义： 各位同学： 视频观看结束，想必大家对这8种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。 英语中动词的时态共有16种。请看下表： 时态的定义：
