新目标七年级上Unit 2 This is my sister SectionA 1a-1c说课稿
Unit 2 This is my sisterPeriod1(1a---1c)说课稿陈艳一、教材分析本单元复习了预备篇单元及第一单元学到的英文名和问候语。
所有的的环节设置都紧紧围绕了一个主题，那就是家庭成员。
在整个单元中家庭成员的称谓以及对家庭成员的介绍和提问，与一个个小任务紧密地结合在一起。
任务由一开始的口头介绍到之后的书面表达，由最初单一的家人称谓到最后连贯的语句，教材较好的体现了教学的渐进性和层次感，使学生在教师的带领下反复地掌握和巩固本单元的生词和新句型。
从而达到能流畅介绍家庭成员的目的。
二、学情分析本课的教学对象是刚进初中不久的七年级新生，这个年龄的学生内心存在着强烈的求知欲和表现欲，但他们注意力易分散，好动，好玩，并且学生参差不齐。
抓住这一特点，一方面要运用直观生动的形象，引发学生的兴趣，使他们的注意力始终集中在课堂上。
另一方面要创造条件和机会，让学生有机会表现自己，享受成功的喜悦，从而增强他们对英语学习的自信心，在学习过程中发展综合语言应用能力。
（二）教学目标1. 语言知识(1)学会正确使用新单词：father mother parents grandmother grandfather brother sister friend(2)掌握介绍他人的句型：This /That is .....These /Those are ......（三）重点与难点(1) 重点:新单词：father mother parents grandmother grandfather brother sister friend介绍他人的句型：This/That is ......These /Those are ......(2) 难点区分名词的单复数形式与be动词、指示代词之间的关系。
三、教学方法1.说教法根据本课教学内容，教学目标和初中学生的特点，我以情景法和任务型教学法为主线贯穿整个课堂教学，并充分利用多媒体辅助教学，创设一个生气勃勃的语言学习环境，激发学生的学习兴趣，调动学生的积极性。
七年级上册This,is,my,sister英语教学设计
七年级上册This,is,my,sister英语教学设计篇一：7上unit2 This is my sister教学设计Unit 2 This is my sister.(第一课时)教学设计校名：贡山一中学科：英语教师姓名：熊飞课题：unit 2 This is my sister. (Period 1— Section A 1a—1c) 课型：听说课；语法课教学时间：45mins教材分析：人教版《新目标英语Go for it》每个单元都有一个Language Goal, 这个Language Goal 其实就是本单元的Topic。
然后所有的课程设计都是围绕着这个话题，无论是Sentence , Vocabulary 还是Grammar。
本单元所有的环节设置都紧紧围绕了家庭成员这个主题。
在整个单元中家庭成员的称谓以及对家庭成员的介绍和提问，与一个个小任务紧密地结合在一起。
任务由一开始的口头介绍到之后的书面表达，由最初单一的家人称谓到最后连贯的语句，教材较好地体现了教学的渐进性和层次感，使学生在教师的带领下能反复地掌握和巩固本单元的生词和新句型。
从而达到流畅介绍家庭成员的目的。
本课时作为单元的第一课，主要让学生学会确认家庭成员并口头介绍家人和朋友。
与此同时让学生了解可数名词的单复数。
学情分析：七年级的学生刚刚全面的学习英语，对英语学习充满了兴趣，求知欲强，乐于表现自己，而且有较强的记忆力和模仿能力。
同时他们在小学学过一些有关家庭成员称呼的单词。
在预备篇第二单元也学过如何介绍物品的方式，这些都为开展这节课创造了较好的条件。
根据学生的知识储备和七年级学生的特点并结合教材设计，我使用了以下的教学方法：首先在对整个课时进行教学设计的时候，从Topic入手，以下列的程序进行：Topic –--Structure —Vocabulary--- Sentence--- Grammar。
其次，用五步教学法;情景教学法；结合“English possible, Chinese necessary.”的教学方法,进行听说结合，模仿操练，反复使用重点单词和句型，由浅入深，由易到难，循序渐进地深化教学内容；再次，把鼓励教育教学法参与到课堂教学中，教师评价多元化并且恰当的使用激励性评语，让学生尽量的参与到课堂教学活动中，有更多的机会说英语，让他们渴望成功的心理得到满足，使他们体验到成功的喜悦。
新目标英语初一Unit 2 This is my sister.教案
Unit 2 This is my sister.一教材分析本单元是七年级（上）第二单元。
主要是让学生学习家庭成员的英文表达以及确认他人家庭成员的简单句问答。
这是交际中的最基本内容。
对于程度好的学生，可以要求其将介绍内容扩展至描述家庭成员的个人情况以及自己与他们的关系。
本单元还将巩固学习指示代词二、学情分析初一的新生刚进入中学阶段学习，他们对身边的同学还不是很了解，本单元的话题正为他们的加深了解创造了良好的机会，再加上他们希望自己的表现能很快得到同学和老师的认可，所以他们的热情和参与度都比较高。
教师应设法激发他们的学习兴趣并设计各种任务型的课堂活动让学生人人都能参与活动，增强他们的英语学习积极性和学习自信心。
大部分同学对于家庭成员的名称有所了解，如何使学生在已有知识的前提下，掌握本单元的知识并进行提升，是我们在备课中应考虑到的问题。
该年龄段的学生有很强的记忆力和模仿能力，但知识的拓展和运用的能力有待培养。
我们教师要充分利用这一点在教学课本知识的同时，教会学生创造性地使用所学知识运用于实践。
三、教学目标1. 知识目标①学习和掌握家庭成员的英文表达。
②用This is…/These are…/That is…/Those are…，句型确认人物。
③用Who’s she/he? ;Who are they ? He’s my brother. They are my grandparents.句型辨认人物。
2.能力目标①学会向他们介绍自己的家庭成员。
②能向他人询问、确认对方的家庭成员。
③能对自己家人的个人情况进行描述。
3.情感目标通过一系列的任务活动，鼓舞学生积极参与活动和积极学习英语，增加了学生用英语表达的自信。
四、教学重点和难点1. 重点：①家庭成员的名称。
②询问、确定他人家庭成员的句型。
2.难点: 利用所学单词与句型进行简单交际和写作。
五．课时划分第一课时（Page7--- Page8 , 1a, 1b, 1c / 2a, 2b, 2c）学生了解家庭成员的英文表达。
