Book 1 unit2 English around the world reading 教学设计

一、教材分析：??????? 本节课上的是人教课标版必修1 Unit 2 English around the world的阅读课The road to modern English。本节课的中心话题是“English language and its development, different kinds of English”。通过对英语语言的发展历史这一话题的探讨，加强学生对英语语言的了解，特别是对英语发展趋势的了解。世界在发展，时代在前进，语言作为交流的工具，也随着时代的发展而变化。由②英语在世界上的广泛使用，它不断地吸收、交融、创新,这就形成了各种各样带有国家、民族、地区特色的英语，没有人们认为的那种唯一的标准英语。通过本课的学习要让学生了解英国英语、美国英语、澳大利亚英语、印度英语、新加坡英语等都有自己的惯用法和不同的发音规律。在完成本节课的学习后，学生能感受到英语语言的多层次和多元化，有助②培养学生的跨文化意识。二、教学目标：??????? 1. 语言技能目标：??????? ①Talk about English and its development, different kinds of English.??????? ②Talk about difficulties in language communication.??????? ③Learn to make dialogue using request & command.??????? ④Learn to transfer from Direct Speech into Indirect Speech.??????? ⑤Learn to give opinions and organize ideas by way of brainstorming.??????? 2. 语言知识目标：??????? （1）重点单词、短语:??????? subway, elevator, petrol, gas, official, voyage, conquer, native, come up, apartment, actually, base, at present, gradually, vocabulary, make use of, latter, identity,fluently, frequently, usage, command （2）功能句式：??????? ①English is a language spoken all around the world.??????? ②There are more than 42 countries where the majority of the people speak English.??????? ③The number of people who learn English as a foreign language is more than 750 million.??????? ④In China students learn English at school as a foreign language, except for those in Hong Kong, where many people speak English as a first or a second language.??????? 3. 情感态度目标:??????? 让学生通过阅读获取有关英语语言发展的知识，扩大国际视“，强化文化意识，激发他们学习英语的热情。三、教学重点、难点：??????? 1. To be able to get the main idea from the text.??????? 2. To be able to solve the problem by analyzing.??????? 3. To be able to use the different learning strategies for different reading purposes.?

四、教学方法：??????? 1. 情景交际法。课堂教学以情景交际教学法为主，尽量给学生足够的听、说、读的机会，联系课文实际，创设情景，引入讨论主题，让学生在交际中学英语。情景的设计注意衔接的自然性，主题的设计强调知识的渐进性和讨论的可行性，并注意德育和发散性思维的培养。??????? 2. 任务型语言教学法。任务型语言教学理论认为：人们使用语言的过程就是一个完成各种各样任务的过程。在本课教学中，我将依据课程的总体目标并结合教学内容，创造性地设计贴近学生实际的任务活动，吸引和组织他们积极参与，使学生通过思考、讨论、交流和合作等 内容过长，仅展示头部和尾部部分文字预览，全文请查看图片预览。 词法的学习来让学生扩大词汇量；

3、充分利用教材中的练习，拓展和巩固词汇；

4、利用配套的辅导材料来巩固所学词汇；

5、利用造句的方式让学生学会运用所学词汇；

6、通过阅读，培养学生在语境中通过上下文来学习记忆和收集整理词汇。

词汇教学也是英语学习中一个最重要的组成部分，它就像盖高楼大厦的建筑材料一样，没有这些材料，高楼就盖不起来。因此，从某种程度上说，一个人的词汇量决定着他的阅读水平。由此可见，在教学中教师应该要求学生在大量阅读的基础上养成做摘记的好习惯，随时随地记录下阅读中碰到的有用的词、短语、精彩的句子和短文，并经常翻阅熟悉背诵，进而多加模仿运用，让优美的词、各种表达法熟记于心，为提高语言运用能力和培养语感，奠定基础。

总之，教师要认真履行新课改倡导的以人为本的理念，面向全体学生，重视学生的个体差异，关注每个学生的发展。在教学中要认真分析每个学生英语学习的具体情况和困难，确定相应的教学目标和要求，关注学生的非智力因素，重视培养他们的意志品质，让他们认识到良好的意志品质是成功的动因，引导他们正确认识英语学科，树立起战胜困难的信心和勇气，进而逐渐养成良好的英语学习习惯。
