1、Unit10教学设计 Section A (Grammar focus 4c)教材来源：初中九年级英语教科书/人民教育出版社2014年版内容来源八年级英语下册第十单元主题： Ive had this bike for three years.课时：第三课时授课对象：八一班学生设计者：梁厚红一、基于课标:1. 理解“语法项目表”中所列语法项目表并能在特定语境中使用。 2.了解常用语言形式的基本表结构和常用表意功能。3.在实际运用中体会和领悟语言形式的表一功能。4.理解并运用恰当的语言形式描述具体的时间和具体行为的发生。二、基于教材本课围绕 “谈论人们拥有某物多长时间 ” 这一话题开展, 使学生掌

2、握与 此有关的词汇并能用现在完成时谈论 。教师运用“任务型”语言教学途径,采取“听、说、读、写 ” 的教学手段, ,激发学生学习英语的兴趣， 获得英语学习的成就感。三、基于学情八年级学生学习教材有五年半的时间了, 对于教材的特点和结构都很熟悉, 此阶段学生,对英语学习的兴趣不太高。对 谈论人们拥有某物多长时间的话题，熟练运用since, for 谈论自己的个人物品并正确区分现在完成时与一般过去时，这对于学生来说有一定的难度，需要老师的指导。 学习目标： 1.掌握现在完成时的用法2. 能听懂谈论人们拥有某物多长时间的话题，能熟练运用since, for 谈论自己的个人物品。3.正确区分现在完成时

3、与一般过去时 学习过程 Step 1 lead in 出示grammar focus下面的典型例句，让学生们先自己观察句子结构，对比现在完成时和一般过去时的不同。eg1. How long have you had that bike over there? 那边的那辆自行车你买了多长时间了？ Ive had it for three years. 我买了三年了。eg2. How long has his son owned the train and railway set? 他的儿子拥有这套轨道火车多长时间了？ Hes owned it since his fourth birthday.

4、 自他四岁生日起，他就拥有了它。eg3. Have you ever played football? 你曾经踢过足球吗？ Yes, I did when I was little, but I havent played for a while now. 是的，当我很小时就踢过，但是现在我有好长一段时间没有踢了。Step 2 精讲点拨 现在完成时1.现在完成时的构成助动词have（has）+过去分词 否定句在 have/has后加not. 一般疑问句把have/has提到主语前. 2.现在完成时的基本用法v表示从过去已经开始持续到现在的动作或状态，可以和表示“从过去某一时刻延续到现在的一段时

5、间状语”连用，如“for + 时间段”、“since + 过去时间点”、“since + 过去时的从句”、“since + 一段时间 + ago”。且for与since引导的时间状语可以相互转换。 站在现在回顾过去 1)表示“影响” 表过去发生的某一动作对现在造成的影响或结果. (多数需要结合上下文语境） Eg. 近的影响 I have just had my breakfast. （影响：不饿) 远的影响，如表示经历等 eg. I have visited the Great Wall before2）.表示“持续” e.g1. My uncle has worked at this fac

6、tory for ten years.= My uncle has worked at this factory since ten year ago. eg2. Ive lived here since 1990自从1990年以来我就住在这里。 eg3.I havent seen him for three years.我三年没有看见他了。 eg4.Shes been at this school since five years ago. 自从五年前以来她就在这个学校。句中动词的特点:此种用法中表示持续性的动作或状态的动词必须是延续性动词 eg1.这本书我买了5年了。 I have bou

7、ght the book for five years. ( ) Ive had the book for five years. ( )eg2. 你哥哥参军多长时间了？ How long has your brother joined the army? ( ) How long has your brother been in the army/been a soldier?

11、与一般过去时的区别 两者都表示过去发生的事情，但一般过去时只 强调过去某时发生的 事情或单纯叙述过去的事情， 不涉及与现在的关系；现在完成时强调过去的事情对现在的影响或结果，主要说明现在的情况。 I saw this film yesterday. （强调看的动作发生过了。）I have seen this film. （强调对现在的影响，电影的内容已经知了。） Put the following sentences into English.1.
