人教课标版高中英语必修四 Unit1 单元总览-新版
Unit1 单元总览教学设计第一部分单元总览1. 教材解读本单元紧紧围绕世界杰出女性成就这一话题,通过介绍中国及其世界杰出女性在不同领域的非凡成就,探讨女性在社会中的地位、价值和贡献,为学生（尤其是女同学）树立成才成长的榜样。
本单元学习可以帮助学生提高自身对妇女社会角色的认识,培养学生的社会责任感,事业心及其全球公民意识,帮助建立正确的性别观。
1.1 Warming Up 为学生展示了来自中法美英等国不同领域的杰出女性,并通过对她们事迹的简要介绍要求学生总结讨论出这些人物的共同点,随后便可得出女性伟人的标准。
在总结这一知识时,教师可以激活学生在book1第五单元对于曼德拉这位英雄的评价知识。
联系先前知识可以有效降低任务难度,帮助学生更好掌握这些女性伟人的基本介绍。
1.2 Pre-reading是Reading 的引入活动。
此部分共有两个问题。
问题一结合warming up中对Jane Goodall 的介绍要求学生思考实验室研究法和野外研究法二者的优势与不足,同时给出自己的理由。
随后学生通过标题和插图等来对文章内容进行一定预测。
1.3 Reading 提供了一篇名为“非洲野生动物学生”的文章,文章首先描述了Jane 和她的同事们在非洲原始森林里观察猩猩的一个片段,并阐述她选择这项工作的重要性及其她所取得的成就。
作为一位女性,她克服野外研究的艰苦,坚持在一线做研究并且取得了突破性成果,同时她强烈呼吁让动物回归自然。
Jane的经历和成就非常明显地凸显了本单元主题,让学生对杰出女性的了解更加深入。
1.4 Comprehending部分的四项练习对理解和思维训练层层递进,既是用来帮助学生更好地理解阅读内容的,又是对学生阅读策略的引导和训练,更是对学生语言表达能力和思维能力的训练。
其中练习一和练习三通过单选和填表格的方式引导学生关注文中的具体事实细节；练习二则要求学生对文章段落大意进行总结从而掌握文章内容；练习四则是基于文章的一些开放性问题,要求学生结合自己的知识水平和认识进行回答。

【Teaching Design】Unit 1 Women of achievementUsing LanguageReading and WritingNew Senior English for ChinaStudent’s Book 4目录一、主题语境二、语篇类型三、授课时长四、课程设计思路七、学情分析八、教学内容九、教学目标十、教学重点十一、教学难点十二、教学方法十三、教学资源十四、教学过程十五、板书设计十六、附录一、主题语境人与社会——科学家与科学研究二、语篇类型介绍性文章——人物类描写三、授课时长40 分钟四、课程设计思路课程设计灵感来源于在新冠疫情期间，师生们看到对李兰娟院士和奋战在抗击疫情最前线的女医护人员的新闻报道，心中崇拜之情油然而生。
与此同时，奋战在防疫检验一线的女社区工作人员、女交警、疫情期间停课不停教的女老师以及为同学们做好在家学习各项后勤保障的母亲等这些我们身边平凡而又伟大的女性都让老师和学生感动不已。
必修四第一单元话题是“卓有成就的女性”，而Using Language部分也是对女医生林巧稚的介绍，因此本人产生了让学生借助文本掌握如何对人物进行描述的技能，对李兰娟院士进行描写，加深学生对伟大女性的了解并向之学习的设计思路。
在确定文本之后，课程设计主要是五个环节：一、导入主题语境，即卓有成就的的女性。
二、对语篇进行探究，找出人物介绍的必要因素。
三、对该类型写作中词汇、句型等进行拓展。
四、进行话题写作并对文章进行打磨。
五、感情升华，使学生对卓有成就的的女性有了新的了解并向她们学习，从而升华主题，达到在文本中培养学生英语学科素养的目的。
本课采用任务驱动教学法，整体设计环环相扣，层层递进，把语言知识学习、语言技能的运用、思维品质发展和文化意识形成有机融入课程内容和教学活动中，为在课堂教学中培养学生的英语学科核心素养进行了有益的尝试和探索。
五、课程主要亮点1、导入新颖导入部分关于对伟大女性的高贵品质这一部分运用了“Flying words”环节，学生看到屏幕上飞驰而过的单词大声读出，这让学生对描述品格的词汇有了更加直观的了解，并帮助学生做好与上节课的衔接以及本节课写作词汇输入的工作。

三维语感教学法让学生在语感训练和课堂展示中能够充分享受语言学习的快乐，学生自主学习、自主展示和自主反思。
（作者单位：荆州市教育科学研究院）三维语感教学法运用系统思维方法，在课程设置上超越单一课型的传统设计方式，构建了一个核心结构是——“五课型”整体教学模式。
展示课，作为三维语感教学法的五课型之一，它以指向学科核心素养的英语学习活动观为指导原则，是变革学习方式、提升英语教与学效果的重要举措。
它从英语学习活动观的视角重新审视课堂教学设计，以学生海量输入和自主学习为前提，重组教学内容，为学生搭建有情境、有层次、有实效的英语学习活动平台。
三维语感教学法中的展示课主要有两种模式。
一种是经典的展示模式，由三个环节组成，即自主秀（Free show ）、统一秀（Required show ）、挑战秀（Challenge show ）。
另一种模式侧重写作训练，由统一秀、挑战秀和写作秀（Writing show ）构成。
下面，笔者以高中英语必修四Unit1-2的教学为例谈经典展示课模式的具体应用。

③(2019·天津卷)Amy, as well as her brothers, __w_a_s__g_iv_e_n___(give)a warm welcome when returning to the village last week.
解析：考查时态和语态。句意：艾米和她的兄弟们上周回到村里 时，受到了热烈的欢迎。根据last week可知应用过去时，as well as连接 并列主语，谓语动词遵循就前原则。这句话真正的主语是Amy，她受到 热烈欢迎，所以用一般过去时的被动语态。故填was given。

三、将主动语态变为被动语态应注意的几种情况
1．含双宾语的主动结构变为被动结构时，有两种方法： (1)间接宾语变为主语，直接宾语不变； (2)直接宾语变为主语，间接宾语用介词to或for引导。
He told us a story. 他给我们讲故事。
被动语态
英语中动词有两种语态：主动语态和被动语态。主动语态表示主语 是动作的执行者，被动语态表示主语是动作的承受者。汉语中常用 “被”“给”“由”“受”等词来表示被动，而英语中由“be＋及物动 词的过去分词”构成。
