人教版八年级下册Unit 2 I'll help to clean up...教学设计(表格式)
Unit 2 I'll help to clean up the city parks. Section A 1a-2c一、设计思路本单元的话题是志愿服务及慈善活动，主要探讨志愿者的活动内容和活动形式，带领学生思考和讨论志愿服务的意义。
结合本单元的话题"volunteering and charity"，设置了疫情期间的志愿者活动这一真实感人的语境，通过明暗两条教学线索来探究本单元的主题。
一是基于教材文本内容。
以电影《 我和我的家乡》为教学明线，根据前五个故事的特点设计了第六个故事——最美志愿者，通过这个故事的三个视频场景将话题引入、词汇学习、听力训练、口语输出、综合实践等教学活动全部巧妙地连接成任务活动链，贯穿整个课堂。
二是基于主题意义探究。
以对“What/How/Why? ”的分析为逻辑暗线，引导学生在真实语境中学习志愿者服务活动有哪些(What)、如何号召更多的人加入志愿者队伍(How)、为什么要成为志愿者(Why)，并通过基于文本、深入文本、超越文本等逐步深入的教学活动，进行本单元主题意义的探究，以此促进学生听说能力的提高和核心素养的培养。
二、学情分析八年级的学生已有一定的语言基础，掌握了一些基本的英语听说技能，对于身边的事也有自己的一些认识和思考，有较强的求知欲和表现。
一部分学生已有初步的自主学习和合作探究的能力，但部分学生仍然存在不自信，羞于表现等思想顾虑，但又希望能得到他人的肯定。
因此在教学中教师采用分层教学，让各个层次的学生尽可能都参与活动中，通过多个小组学习活动降低学习的难度，使学生们都学有所获、学有所用，并能体验到学习的喜悦。
三、教学目标1.语言能力目标：(1)能正确使用下列词汇: volunteer, sign, notice, clean up, cheer up, put off, give out, come up with, hand out, call up;(2) 能使用情态动词could 表达建议。

【设计】牛津上海版英语八下Chapter2PollutionFightersword教学设计
【关键字】设计Chapter Two Pollution Fighters章节分析（一）综述本单元的Reading部分的文章是关于“树和环境”。
通过一名中学生采访科学家来了解“树”对环境保护所起的作用。
“污染”问题是一个旧话题，在6B Module 1The Natural Elements 和教材后面的Project 1 The Environment 都谈论到环境与污染的问题；Module 3 Natural Elements Unit 4 Forests and land中谈到了森林，实际上就是谈树的作用和用途。
其中的大部分内容都是我们的学生很熟悉的，所以老师在引入新课时，可以从学生们熟悉的话题“森林”谈起，很自然的进入新课内容。
本单元的Listening部分也是围绕主题，通过Completing a notice的形式，进一步让学生了解树的作用，从而积极投入到“植树战役”中去。
Language部分介绍了现在进行时(the present continuous tense)的用法。
Speaking部分围绕本课的主题讨论How to fight pollution? 我们可以把这部分内容放在Post-reading环节，让学生进行讨论。
Using English部分(The index) 老师可以告诉学生the index 与the contents page 都可以帮助我们快速了解一本书的信息，只是the index 的排版大部分在书后，而且是以字母循序排列的，有主题，比较详细而the contents page 的排版在书的前面，按页码排序。
Writing部分是为学校报纸写一篇有关工人们是如何建造一个sitting-out area的文章。

II. 教学设计：1. ReadingStep 1 Pre-reading1)老师可以通过复习旧句型：What can we get from forests 引出本单元的主题。
然后让学生根据图片一问一答做 pair work，来了解 What good are trees 当然除了老师提供的图片以外，也可以让学生根据自己了解到的知识自由发挥。
2)老师与学生一起得出结论：Trees are very useful and important. 老师接着问学生：What else do you know about trees How long do trees live 然后让学生来做一个与树有关的quiz。
通过这个quiz让学生知道 Trees are pollution fighters.老师还可以充分利用教参中的Notes来帮助学生进一步了解树是如何与空气污染、水污染和噪音污染作斗争的。
同时帮助学生解决部分Reading中的生词，如：chemical, produce, release, oxygen, nasty等等。
Step 2 While-reading（这是本课的重点部分）1)第一遍阅读文章，要求学生根据上下文的内容和线索猜测词意。
2)第二遍通读全文，理解文章意思，并完成Ex. D (page 18)、Ex. E (page 19)。
提醒学生阅读时注意阅读方法的使用。
比如，在做Ex. D时，使用scanning即跳读的方法寻找具体问题的答案。
在做Ex. E时，使用skimming即略读的方法，注意文章中的主题句和关键句。
3)听课文录音。
4)重点词汇及句式讲解。
