(3 mins)Teaching aim: Enable students to realize that too much hunting by people is the most important reason for animals’ dying out through some pictures and a question.Picture 1: This is an Tibetan antelope which is very rare. People kill them for their fur, skin and meat.Picture 2: South China Tiger. They are searching for food which means they don’t have a good habitat.Picture 3: Elephant. People kill elephants for their ivories, which are very dear. The ivory has been traded among foreign countries.T: Here we must think about a question: why are these a nimals dying out?Ss: Hungry, hunting......T: More pictures......Therefore, the most important reason for their dying out is too much hunting, by whom?Ss: By people.T: Right.

(5 mins)Teaching aim: Enable students to match the main idea of each part by skimming.T: This passage is a story, so we can’t pick out the topic sentence in each part. Then we need to summarize the main idea of each part, but how? Depend on what?Ss: ......T: Key words. Do you still remember? Look at these three sentences in the screen and pick out key words in each sentence. (S1: antelopes; why. S2: get a lot. S3: elephant; good example.) Now finish the task.

One, two, go.Ss: Locate the key words into the concrete position in the passage, and then look ahead and behind until you find the answers.T: Two points. “Locate”and “look ahead and behind”. Now use this method to read the passage in detail. Three charts for you, about 6 minutes. You are to discuss in groups of six and I will ask some groups to share their answers. Now, begin!Chart 1(para.1):Ask some representatives to check answers. Then read the three sentences together to briefly summarize para.1.Chart 2(para.2):Ask some representatives to check answers. Then read the three sentences together to briefly summarize para.2.Chart 3(para.3-4)powerfuAnswer these questions together and all the boys read these sentences.Evaluate students: Most of you did a good job in this task. So congratulations, my dear boys and girls (clap hands). Pay attention to the method especially when you meet so many new words.Step 5 Summarize. (3 mins)Teaching aim: Enable students to make a brief summary of the passage based on the blackboard design.Make a summary of the whole passage based on the blackboarddesign from the left to the right (the title, animals, places, how to go, main idea of each part and of the whole passage).Step 6 Retell the passage.

It flew away to Tibet in China first, where she saw an antelop e. The antelope told her that they were killed (kill) for the wool.Then they went to Zimbabwe, where Daisy saw an elephant. Farmers used to hunt them without mercy. Now they allowed tourists to hunt only a certain number of animals if they paid the farmers. The problem was solved.In the thick rainforest, a monkey was rubbing a millipede insect which contains a powerful drug to protect (protect)him from mosquitoes.

人教版必修2高中英语Unit4TeachingPlanofWildlifeProtection教案
1 / 7Book 2 Unit 4 Teaching Plan of Wildlife ProtectionGrammar Exploration一、教材分析本单元是人教版必修2的第四单元，是以保护动物为话题，旨在通过本单元的学习使学生了解很多动物已经灭绝或濒临灭绝，从而认识到保护动物的重要性和必要性；通过探讨保护动物的措施和建议，引导学生发表自己的见解和看法；通过进一步讨论提出有效的保护措施，唤起学生保护动植物、维护生态平衡、保护我们家园的责任感。
并能写信表达自己保护动物的方法与建议，力求正确表达自己的意图并解释原因，并能正确使用被动语态的现在进行时。
本节内容Discovering useful structures 为“现在进行时的被动语态”，以课文内容为载体，要求学生能够使用该语法结构表达自己的观点。
二、学情分析1. 本单元的语法内容并不复杂，学生在初中阶段就已学过现在进行时和句子的被动语态，只是未学习将两者合二为一所表达的语法现象，因此学生在其结构的理解上容易混淆。
在本单元的前两个单元学生已经学习了现在完成时的被动语态和一般将来时的被动语态，因此之前所学知识可以正迁移到新知识上来；2. 本班是一个中等水平的文科实验班，学生的学习习惯较好，课堂参与度较高，因此，学生能够通过小组探究学习的方式，探讨出要求掌握的语法结构，并且通过小组协作的方式，运用所学的语法结构编出短剧，以达到学以致用的目的与保护野生动物的情感共鸣。
三、教学思路本堂课共分为三个板块：热身，发现规则和运用规则三个板块，以一只藏羚羊的遭遇与诉求将这三个部分串联起来。
热身部分，通过呈现两组图片（每组图片间都相关联）和关键词，让学生描述图片所表达的现象，达到初步感知语法结构的目的；发现规则部分，首先，要求学生找出课文中所有含有“现在进行时的被动语态”结构的句子，并分析其基本结构（be being done），其次，阅读一封来自藏羚羊莹莹写给人类的信，让学生深入到语境中进一步探讨现在进行时的被动语态的各种结构，如：肯、否定句，一般、特殊疑问句及其用法和意义；运用规则部分，让学生以藏羚羊莹莹的身份编一个短剧（运用现在进行时的被动语态，现在完成时的被动语态和一般将来时的被动语态），以求达到学以致用、复习和保护野生动物的情感目标。
【人教版】高中英语必修二：Unit 4 Wildlife Protection 教案
Unit 4 Wildlife Protection I. 单元教学目标II. 目标语言II. 教材分析与教材重组1. 教材分析本单元以保护动物为话题，旨在通过本单元的学习使学生了解很多动物已经灭绝或濒临灭绝，从而认识到保护动物的重要性和必要性；通过探讨保护动物的措施和建议，引导学生发表自己的见解和看法；通过进一步讨论提出有效的保护措施，唤起学生保护动植物、维护生态平衡、保护我们家园的责任感。
并能写信表达自己保护动物的方法与建议，力求正确表达自己的意图并解释原因，并能正确使用被动语态的现在进行时。
1.1 Warming Up首先帮助学生明确保护野生动物的原因以及方向。
旨在通过图片和表格引导学生讨论当今我国珍稀动物的现状。
以panda、Milu Deer、South China Tiger 为例，通过对这些珍惜动物所面临的问题、在中国的栖息地以及采取措施其后对比所做的报告，学生能够用已有的知识和经验讨论在中国处于保护状态下的濒临灭绝动物。
从而有效地引导学生关注本单元话题，关注动物生存现状。
1.2 Pre-reading是Reading的热身活动。
通过回答两个问题引导学生讨论自己所知道的濒临灭绝的动物并思考灭亡的原因。
同时要求学生通过阅读文中的图片和标题来猜测文章的内容。
1.3 Reading是一篇童话故事，讲述Daisy 乘坐飞毯跨越时空，在不同个国度、不同地区与生存状态不尽相同的和藏羚羊、大象、猴子对话的神奇经历，展示了Daisy逐渐认识保护动物重要性以及学习如何保护动物的经历。
动物们讲述了各自的处境，唤起了Daisy对动物的热爱以及保护动物的责任心。
从而号召人们热爱动物，保护动物，从我做起。
1.4 Comprehending考察学生对阅读内容的进一步理解与对所学知识的综合运用、迁移。
练习1要求学生根据阅读文的内容回答问题。
这四个问题设计到濒临物种生存现状，保护这些物种所取得成效的措施、保护动物栖息地的重要性以及决定保护成果能够的必要措施。
高中英语必修二U4Wildlifeprotection教学设计.docx
高中英语必修二U4 Wildlife protection教学设计1.整体设计思路、指导依据说明本节课体现的是《普通高中英语课程标准》规定的课程性质和理念：“使学生在义务教育阶段英语学习的基础上，进一步明确英语学习的目的，发展自主学习和合作学习的精神；在加强对学生综合语言运用能力培养的同时，注重学生用英语获取信息、处理信息、分析问题和解决问题的能力以及用英语进行思维和表达的能力。
”本节课以新课程标准的一些核心理念为依据，以任务型语言教学为主，通过实际生活中的真实语境，激发学生学习英语的兴趣，寓教于乐，倡导小组表演活动，小组讨论，鼓励学生全体参与课堂，在体验、实践、合作与交流的学习方式中，培养学生用英语表达的能力，理解保护野生动物的重要性，达到培养学生的社会责任感，提高思考和判断的能力，进而增进跨文化理解和跨文化交际意识。
本节课的设计重视课前的导入，重视课中学生的小组角色表演。
2. 教学背景分析教学内容分析：本节课必修二第四单元 Wildlife protection 的 Reading 部分。
本单元的话题“野生动物保护” 。
Reading 是整个单元的核心部分，是Warming up 的延续和升华。
此外，大部分的重要词汇和句型结构都在这个课时中呈现出来。
完成本节课的阅读，为本单元目标的完成作了很好的铺垫。
也是培养学生阅读能力的重要渠道，发展阅读技能和策略的必经之路。
文章介绍了一个叫Daisy 的小女孩在梦中经历的一次奇妙的飞毯飞行。
通过女孩和藏羚羊、非洲象、猴子的对话，学生进一步意识到野生动物的生存环境日益恶化以及保护野生动物的行动刻不容缓。
学生情况分析：教学对象为高一学生，所教班级的学生思维活跃，有强烈的求知欲望，认知能力比初中有了进一步的发展，到了高中逐渐形成用英语获取信息、处理信息、分析问题和解决问题的能力，具备一定的阅读理解能力，不再单纯地满足教科书上仅有的知识，有获取更多信息的欲望。
笔者注重提高学生用英语进行思维和表达的能力。

高中英语必修2说课稿Unit4WildlifeProtection
高中英语必修2说课稿 Unit 4 WildlifeProtection高中英语必修2说课稿 Unit 4 Wildlife Protection大家好，今天我要介绍的课是普通高中课程标准实验教科书英语必修2第4单元Wildlife Protection的阅读部分。
下面我将从以下四个方面阐述我的课：教材分析^p 、学情分析^p 、教学方法、教学步骤和板书设计。
一、教材分析^p ：(教材内容分析^p ，教学目的,教学重点和难点)首先，我来讲下我的教材分析^p 。
这主要包括教材内容分析^p ,学情分析^p ，教学目的和教学重点和难点四个方面。
1.教材内容分析^p这篇阅读材料紧扣本单元的中心话题“野生动物保护的重要性”，讲述了一个叫戴西的小女孩在梦里和一些野生濒临灭绝的动物交谈，知道了保护野生动物的重要性，既是对前面热身部分的升华，也是这单元的主题内容和词汇学习的重点。
这篇文章构造非常明晰，是按戴西在梦中的的三次飞毯经历来分段的，但段落大意不是很明确。
此外，在这篇文章中出现的生词不是很多。
〔下面，我来讲下对学生学情的分析^p 〕2.学情分析^p学生对本单元的主题“野生动物保护”的话题是非常的熟悉，而且学生们对各种各样的动物也非常的感兴趣。
高一现阶段的学生也已经掌握了根本的像寻读，略读，概括等阅读技能，他们也能就一些问题进展英语对话讨论。
但是，学生对文中出现的组织WWF并不清楚，对有些句子所隐含的话外之音也不是很清楚，也对独立解决一些现实的问题感到困难。
3.教学目的本节课的教学目的包括知识目的、语言技能目的、情感目的、文化意识和学习策略目的。
语言技能：1〕学生可以应用不同的阅读技能得到所需的信息；2〕在略读后，学生能概括各段段落大意；3〕学生可以分析^p 作者某些句子的写作意图，像“No rainforest, no animals, no drugs” and “And there are always WWF.”语言知识：1〕学生能知道更多的关于为什么一些动物濒临灭绝以及如何保护它们；2〕通过学习大部分学生可以掌握并运用重要词汇: mercy, importance, contain等等；情感态度：学生可以认识到保护野生动物的重要性；文化意识：学生能对WWF组织有一定的理解。
