1、现在完成时(复习)教学设计一、教学目标：1、 复习现在完成时的基本构成及用法。2、 巩固现在完成时的易错考点。3、 结合中考，增强对现在完成时的掌握。二、教学重点：复习巩固现在完成时的用法及易错考点。三、教学难点：让学生熟练掌握并准确使用现在完成时。四、教学过程：Self-introductionHello! Boys and girls! I am Zhai Peng from Harbin No.163 Middle School. Im so happy to be here with you. Today, well share a lesson together, Ok? Now,
2、class begins!Step1： Free talk.1. Have you ever been to Harbin?2. How many times have you ever been there?3. How long have you been at this school?设计意图：与学生互动，消除陌生感，循序调动学生的积极性，导入本课话题。Step2： Presentation.首先，让学生以小组为单位归纳整理学过的与现在完成时相关的知识。然后在幻灯片上梳理出来现在完成时的构成，用法以及易错考点。1、现在完成时谓语动词的构成：助动词have/has +pp（过去分词）2、现
3、在完成时的句型结构：肯定句： S+ have/has + done 否定句： S+ have/has + not+ done 一般疑问句： Have/Has + S + done ?肯定回答：Yes, S + have/has. 否定回答：No, S + have/has + not.特殊疑问句： Wh- + have/has + S+ done ?3、现在完成时的用法（1）表示过去发生或已经完成的某一动作对现在造成的影响或结果， 常与already, yet, ever, never, just, before等词连用，也能够和包括现在在内的时间状语（如these days, so far等
4、）连用。注意：already 和yet的区别：already 多用于肯定句；yet多用于否定句和疑问句末。（2）表示过去已经开始并持续到现在的动作或状态。能够和表示从过去一直延续的到现在的时间状语连用，谓语只能用延续性动词。通常和for, since 引导的时间状语连用。for + 一段时间，如for a week, for 3 years, for a long time,since +时间起点；since+一段时间+ago；since+从句(一般过去时)。如since 2 oclock, since yesterday, since3 years ago, since I came her
5、e等注意： 对for或since引导的时间状语提问，必须用How long。设计意图：让学生以小组为单位归纳整理学过的与现在完成时相关的知识。为下一环节做好准备，同时调动小组合作积极性。Step 3： Revision.现在完成时要注意三个分清。1、 要分清和一般现在时的区别。现在完成时虽然动作时发生在过去，但只强调现在，不能和表示过去的时间状语连用。而一般过去时只表示过去发生的动作或状态，和现在没相关系，只和yesterday, last night, three years ago等表示过去的时间状语连用。2、 要分清have been to , have gone to 及 have b
6、een in.have been to 表示以前去过某地现在已经返回；have gone to 表示已经去了某地未归；have been in 表示去了某地并待在那里一段时间（通常和for+段时间连用）。3、 要分清瞬时性动词和延续性动词。在现在完成时的中， 瞬时动词不能和for, since 引导的时间状语连用，必须转换成能表示动作延续的延续性动词。最常见的有：buy-have, borrow-keep, leave-be away (from) die-be dead,come-be here/be in join-be in /a member of begin/start-be onb
7、ecome- beopen- be openclose- be closedTRUE OR FALSE：1. 我买了这本书五年了。I have bought this book for five years. FI have had this book for five years. T2. 这位老人已经死了十年了。 The old man has died for ten years. F The old man has been dead for ten years. T设计意图：在复习基本知识和用法的基础上，加强双基训练，针对学生易错的考点进行巩固强化。Step 4: Excises.链
