Unit 4 Humour Lesson 1 What’s So Funny Grammar 课件-2025-2026学年高中英语北师大版（2019）选择性必修第二册

该高中英语课件聚焦过去完成进行时、现在完成进行时和将来进行时三大时态，通过“Activate and share”环节以趣味问题及笑话导入，先梳理完成进行体等四种语法体概念，再搭建从基础语法体到目标时态的学习支架，帮助学生建立知识脉络。 其亮点在于融合语言能力与思维品质培养，通过时间轴解析动作顺序、表格对比时态核心视角（如过去完成进行时“过去的过去+持续未完成”与过去完成时“完成结果”的例句对比），结合语境化例句（如将来进行时礼貌询问用法）提升理解。练习设计强化应用，助力学生掌握时态差异，教师使用可高效落实语法教学目标。

Unit 4 Humour Lesson 1 Grammar Activate and share How many grammatical aspects does the English tense have? What are they? 01 02 03 04 Perfect continuous 完成进行体 It is a combination describing a completed part of a continuous action. 动作完成一部 分，还要再进 下去。 Continuous/ Progressive进行体 The action is still happening at a time of reference. 动作正在进行。 Perfect 完成体 Actions are finished. 动作已经完成。 Simple 完成体 The action is not specified as continuous or discrete. 动作不在进行中，或没有详细说明的。 过去完成进行时 Grammar focus 现在完成进行时 将来进行时 1.过去完成进行时 动作在过去的某个时间点之前已经开始，并持续到该点，突出动作的持续过程或其持续时间长度，而不仅仅是动作的完成。 had been doing 注意： 否定形式不常用：这种时态很少用于否定句，在表达否定含义时，通常用过去完成时来代替。 He had not practiced​ English for many years. He had not been practicing​ English for many years. 没有被动语态：过去完成进行时没有被动语态。如果需要表达被动的含义，应换用其他时态。 与过去完成时态的区别： 过去完成时强调动作在另一个过去动作或时间点之前已经完成，侧重结果。而过去完成进行时强调动作的持续过程，至于该动作是否完成，则不一定。 She had cleaned​ the office. (办公室已经打扫干净了。)强调完成的结果。 She had been cleaning​ the office. (她之前一直在打扫办公室。)强调打扫这个动作持续了一段时间，但办公室不一定已打扫完毕。 2.现在完成进行时 肯定句： 主语 + have/has been + 动词-ing 否定句： 主语 + have/has + not + been + 动词-ing 疑问句： Have/Has + 主语 + been + 动词-ing? 表示从过去持续到现在，并且可能继续的动作；强调动作的持续性和未完成性。常与 for（一段时间）、since（一个时间点）、all day/morning 等时间状语连用。 动作在一段时间内反复发生，强调这个重复的模式一直持续。这个时态也一般没有被动语态。 I have been calling him all day, but he never answers. 我一整天都在给他打电话，但他从来不接。 （反复打电话这个行为持续了一整天。） He has been complaining about his job for as long as I can remember. 从我记事起，他就一直在抱怨他的工作。 （抱怨是重复发生的，并持续至今。） “I _____________(wait) for the bus for twenty minutes.” she complained. “I ________________(wait) for the bus for twenty minutes.” she thought. have been waiting have waited Practice 3.将来进行时 将来进行时描述在将来某个特定时间点或时间段正在发生的动作。它像一部摄像机，预先放置到未来，拍摄那个时间点“正在进行的画面”。 肯定句：主语 + will be + doing 否定句：主语 + will not (won’t) be + doing 疑问句：Will + 主语 + be + doing？ 2. 询问未来计划（比一般将来时更礼貌、更不具压迫感） 用将来进行时询问别人的计划，听起来像是“我猜你已经有安排了，能告诉我吗？”，而不是“你打算做什么？”，因此显得更礼貌、更随意。 常见时间状语： 将来进行时通常与明确的未来时间点或时间段连用。 at + 具体时刻: at 5 o‘clock, at this time tomorrow in + 时间段: in an hour, in two days this + 时间: this evening, this time next week 由when, while等引导的时间状语从句 (从句中用一般现在时) Complete the sentences using present perfect continous, past perfect continous or future continous where appropriate. P11 1. The eager fans _________________ (wait) for six hours before they finally got the tickets for the football match. 2. I _____________________ (look for) that for weeks — where did you find it? 3.
