Book4 Body Language Showing Our Feelings教学设计 河北饶阳中学王晓莉一、教学内容(Teaching Content) 人民教育出版社普通高中课程标准试验教科书英语必修四Body Language第三课时---Showing Our Feelings. 二、教学设计(Teaching Plan) （1）教学思路 本单元的中心话题是“身势语”，各项活动的设计都围绕着这个主题进行。身势语是非语言交际手段中非常重要的一个方面，它通过无声的语言表达一个人的内心世界。与有声语言一样，身势语也是文化的载体，在跨文化交际中起着举足轻重的作用。了解身势语的不同文化涵义并正确地加以运用，会在交际场合中起到意想不到的好效果。通过本堂课的学习，学生们能够了解世界各地的人们表达各种各样的情感、愿望和态度，“读懂”我们周围人的意思。 整个教学过程以“ 以学生为学习主体” 为设计理念，采用设置任务和小组讨论的形式组织教学，将学生的自主学习调动起来并把这样的活动作为课堂的主体，引导学生完成学习任务。 （2）课前准备 要求学生预习课文Showing Our Feelings，并找出我们周围人们是怎样表达快乐、不高兴、愤怒、厌烦等情感的。 三、学生情况分析
我们的学生绝大多数来自农村，学习英语的条件有限，大部分是上了初中才开始学习英语，所以英语意识淡薄，知识薄弱。面对这样一群孩子，吸引他们对英语的兴趣是关键，因此我在这节课中使用了大量的图片，一方面吸引他们的注意力，引起兴趣，另一方面很大限度地帮助了学生们对这篇课文的理解。 四、三维目标（Teaching Aims) （1）知识目标(Knowledge Aims) 让学生了解“身势语”的概念，掌握身势语的不同文化涵义并正确地加以运用。通过阅读熟悉本课的相关单词、短语及重点句型，如spoken, unspoken, likely, be likely to, in general, at ease, etc. （2）能力目标(Ability Aims) 提高学生的阅读能力，训练学生skimming和scanning的阅读技巧，提高学生归纳总结、善于提取有用信息的能力; 在教学总过程中锻炼学生听、说、读、写各方面的技能，培养学生独立思考和合作学习的能力; 快速获取信息和处理信息的能力。 （3）情感态度与价值观(Emotional Attitude and Point of Value) 通过学生参与英语教学活动，增强其学习英语的主动性和积极性；通过对世界各国身势语及其情感表达方式的介绍，开拓学生的视野；通过自主学习和合作学习，使学生们能够了解世界各地的人们表达各种各样的情感、愿望和态度的方式，并对以后的工作生活产生一定的影响。 五、教学重难点（Teaching Key and Difficult Points） Teaching Key Points：

教学过程 一、课堂导入 要求学生以小组形式完成一个表格填充，列出中国的五个节日和这些节日的 时间、庆祝的内容以及节日里人们的所作所为。激发学生的阅读兴趣，为本 单元Reading部分的世界节日做好铺垫。 二、复习预习 以提问学生方式复习上节课所学习知识。同时以习题形式预习新课。 三、知识讲解 考点/易错点1 重点单词与短语学习 mean n.意义，意思v. 意味；想要 (回归课本P1)

(4)break out (战争、火灾等)爆发；(疾病)突然发生。无被动语态。 (5)come about “发生，产生”，常指偶然发生的事情。指要解释或说明事情发生的理由，

Unit 4 Body language Ｉ．单元教学目标 II．目标语言
Ⅲ．教材分析和教材重组 1．教材分析 本单元以Body Language——“体态语”为中心话题，具体涉及什么是“体态语”，如何理解“体态语”，以及“体态语”的跨文化性等。本单元的语言技能和语言知识也都是围绕“体态语”这一中心话题设计的，旨在通过单元教学，用听、说、读、写、做(表演)等多种形式，让学生正确认识和掌握“体态语”在交际中的作用和意义，使学生明确“体态语”在人类交际中的重要性，了解“体态语”在不同民族、不同文化交际中的多样性；使学生在今后的日常生活、学习、工作和交往中尽量减少或避免运用“体态语”时可能产生的误解，提高他们的“语言交际”能力和“非语言交际”能力。 1.1 WARMING UP 以列表对比（填充及增补）的形式，并通过WARMING UP 的活动，让学生了解有声语言与“体态语”的对应关系，了解语言意义与行为意义（“体态语”）在交际中具有同等重要的作用。同时，学生在听、说、做（即表演
“体态语”的动作）中能够增进对语言交际的感性认识，为他们在阅读过程中上升到对语言交际的理性认识打下基础。 1.2 PRE-READING 通过提供三个关于不同文化背景下“体态语”的问题，启发学生思考我们所学习的“语言”的目的、形式、功能。通过引导学生联系自己日常生活的实际，提高学生努力学习英语的积极性和自觉性；同时培养学生留心社会、关注生活的洞察力，为引导学生进一步“阅读”作好准备。 1.3 READING 是一篇介绍性（记叙文）体裁的文章，主要介绍了各种文化背景下的“体态语”的异同，为学生提供了来自不同国度、不同语言文化背景的“体态语”及其在交际中的异同和影响的具体例证。学生也可以结合自己在语言交际中所遇到的实际例子来进一步理解“交际，毫无问题可言吗？”这一主题。 1.4 COMPREHENDING 包括八个问题（前5个旨在检查学生对阅读材料细节的理解，6~7旨在引导学生对“体态语”的意义及文化差异的思考，第8个检查学生能否通过细节进行推理判断），通过对来自不同国度、不同语言文化背景的六个角色对待男女不同性别所使用的“体态语”异同的（学生在老师指导下的自我或小组讨论后的）归纳，进一步熟悉和掌握“体态语”在不同语言文化交际中的作用和意义。 1.5 LEARNING ABOUT LANGUAGE 分词汇和语法两部分。词汇部分由“本单元重点词汇英文释义”，“词语填空”和“词性变换”三项内容构成，语法部分由两大方面组成：一是让学生自己通过在课文中寻找相关语法的句子并按其语法功能分类，二是根据学生的认知规律安排该语法项目的练习让学生进行操练。整个项目通过三个练习和一个游戏，以及语法结构讲练，进一步巩固本单元所学词汇（尤其是课文中的黑体字），学习“现在分词”结构用作定语和状语，并通过操练，以收到“学以致用”、“熟练生巧”的效果。 1.6 USING LANGUAGE 通过增加阅读篇目“Showing Our Feelings”来拓展学生在“体态语”方面的知识视野，并通过“True” or “False”判断练习和问题讨论，使学生进一步明确“体态语”对人们在日常交际中了解对方情感、思想、态度等方面所起的作用。同时要让学生认真对待自己的“体态语”，并在日常交际中“听其言”（Listen to them）、“观其行”（Watch them）。此外，该部分还通过听、说、读、写四个方面来巩固本单元所学内容和语言交际项目。
