九年级英语全册 Unit 6 When was it invented Section A教学设计 （新版）人教新目标版-（新版）人教新目标版初中九年级全册英语教案.doc

Unit6 when was it invented
设计思路
《英语课程标准》明确指出：课程要从学生的学习兴趣、生活经验和认知水平出发，倡导体验、实践、参与、合作与交流的学习方式，发展学生的综合语言运用能力，使语言学习的过程成为学生形成积极的情感态度、主动思维和大胆实践、提高跨文化意识和形成自主学习能力的过程。
在本课的任务型语言教学中，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生活实际的任务活动，吸引和组织他们积极参与，使学生通过观察、思考、讨论、交流和合作等方式，在一种自然、真实或模拟真实的情境中体会语言、掌握语言的应用。
材料分析

《新目标英语》中的具体语言目标是通过各种各样的Tasks来实现的；学生需要运用具体而特定的行动来完成一定的交际任务。整个教学过程中，各种语言结构与语言功能与不同的学习任务有机的结合。任务活动所谋求的效果不是一种机械的语言训练，而是侧重在执行任务中学生自我完成任务的能力和策略的培养；重视形式在完成任务过程中的参与和在交流活动中所获得的经验。因此本节课我将始终引导学生通过完成具体的任务活动来学习语言，让学生为了特定的学习目的去实施特定的语言行动，通过完成特定的交际任务来获得和积累相应的学习经验，让学生在用中学，在学中用。

教学反思
将主动语态变为被动语态，要求学生自己去发现其中的规律，充分发挥他们的主观能动性。教师可以根据学生的兴趣,在完成本活动前或活动后补充关于发明的背景知识,并鼓励学生对自己感兴趣的发明进行课外阅读和探究,并于同学分享,这样做的目的是给学生创设机会,鼓励学生对科学发明和发明家们探索的故事产生探索的故事产生探究的兴趣,有利于培养学生积极探索和勇于创新的科学探究精神.
背景材料的补充
1,Tell something about Lu Yu and his Cha Jing
Lu Yu “the saint of tea” mentioned Shen Nong in his book Cha Jing. The book describes how tea plants were grown and used to make tea. It also discusses where the finest tea leaves were produced and what kinds of water were used.  
It is believed that tea was brought to Korea and Japan during 6th and 7th centuries. In England, tea didn’t appear until around 1660. The tea trade from China to Western countries took place in the 19th century.
2.茶的文化
Chinese tea has a history of over 5,000 years, during which a series of unique tea culture have come into being, covering from tea plant cultivation and conservation, tea-leaf picking to processing and sampling tea. Tea-leaves are mainly produced in the southern area to the Yangtze River for mild climate and fertile ground there, such as the provinces of Zhejiang, Yunnan, Guizhou and Fujian. There produce an abundance of renowned tea varieties, e.g. Longjin, Wulong, Pu’er, Tieguangyin.
Tea culture is one of the common traits shared by all the 56 ethnic groups in China. Many Chinese people believe that a day is not perfect without a cup of tea. Either in the warm southern mountain area or on the frozen northern grassland, stuff like Gongfu tea, buttered tea and milk tea are all among the favorite drinks. Furthermore, both ancient and modern Chinese people tend to indulge in elaborating on poems, essays, dances and dramas on the tea.
茶在中国已经有5000年的历史。在漫长的历史中，围绕茶的栽培、养护、采摘、加工、品饮形成了一整套独具特色的茶文化及相关艺术。长江以南是中国茶叶的主产区。浙江、云南、贵州、福建等地气候温和，土地肥沃，十分适合茶叶的生长，造就了龙井、乌龙、普洱、铁观音这些驰名中外的名品。
茶文化是中华多民族文化中的一个共同特征。五十六个民族都有饮茶的习俗。许多中国人在生活中不可一日无茶。不论是在温和潮湿的南方山区，还是冰天雪地的北方草原，工夫茶、酥油茶、奶茶都是人们特别喜爱的饮品。以茶为题的诗歌、散文、舞蹈、戏剧更为人们特别津津乐道。
