单元：Unit2Language板块：Wordpower课堂设计指导思想：Wordpower旨在科学地、有效地、有趣地扩充学生的词汇量。Wordpower在设计上采用了与本单元主题相照应的思路，内容上不受课后词汇表的限制，期冀在同一语意场中通过语境的辅助以及构词法等相关知识的输入实现学生词汇的扩展。本节课是以听、说、读为主的词汇教学课。词汇教学应当“有层次”并兼顾“知、情、意”。首先，“有层次”是指词汇教学应努力遵循认知规律，按照学生温故知新—探索新知识—使用新知识—巩固新知识的客观规律进行教学。其次，兼顾“知、情、意”是指词汇教学要有：知——词汇知识、学习策略以及词汇所蕴含的文化知识的输入；情——师生间的情感互动、学生的情感融入与兴趣的激发、以及情感体验的过程；意——人文精神和人生意义的体悟与提升。Teachingaims:1.Gettoknowthenamesofsomecountriesandtheirofficiallanguages.2.LearnthedifferencesbetweenformalandinformalEnglish.3.Getsomebackgroundknowledgeofrelatedtopics.4.Todiscusstheimportantwaysthathelptoachievebetterunderstandingbetweenpeoplefromdifferentcultures.Teachingprocedures:Step1Lead-inTheteacherintroducesthetopicoftheUN.BasicfactsabouttheUN:Fact1:WhenwastheUnitedNationsfounded?Aclue:Intheyear2005theUNcelebratedits60thbirthday.(backgroundknowledge)Thestudentsaresupposedtogettheanswer:In1945.Fact2:Whywasitfounded?Informthestudentsofthefollowingaspects:TheUNworkson:①peaceandsecurity②humanrights③humanitarianaffairs④internationallaw⑤economicandsocialdevelopmentInaword,itworksoninternationalaffairs.Fact3:Howwasitorganized?ShowthestudentsthediagramoftheUNsystem.Pointoutthreeofthemwhichthestudentsmightbefamiliarwith:UNESCO,WHO,WTO.Introducethe6principalorgansoftheUN.Offerthestudents2websiteswheretheycanfindmoreinformationabouttheUN.(learningstrategy:tohelpThestudentslearnmorebythemselves)Fact4:Whataboutitsmembers?Askthestudentstoreadtheparagraphonpage27.(task-basedreading)Task:Answerthefollowingquestions:①HowmanycountriesaremembersoftheUN?(191)②Canyougivemesomeexamplesofthememberstates?(China,France,etc.)③Howmanylanguagesarespokenintheworldtoday?(About6000)Checktheanswersandgivemoreinformation.【设计说明】结合课文中的信息，为学生了解联合国提供了一系列的背景知识：联合国建立的时期、目的、组成、以及成员国和使用语言等等。本课教学素材比较简单，如果不增加一定的文化和相关知识的输入，则内容过于单薄。作为导入，介绍相关信息，一方面是为之后的话题提供过渡，另一方面，也拓宽了学生的视野并为学生进一步了解知识提供了信息资源。Step2Countriesandlanguages:①Dividethestudentsinto2groups.②Presenttherule.Somenationalflagsorrelatedinformationwillbeshownonthebigscreen.Whenastudentseeanationalflagappearorhecanguesstheanswerfromthegiveninformation,he/sheshouldstandupimmediatelyandtelltherestofuswhatnationalflagitisandwhatofficiallanguagepeopleuseinthatcountry.Andifhe/shemakesitright,his/hergroupwillgetonepoint.③Givethestudentssometimetoprepare.Makesuretheyknowhowtorecognizedifferentnationalflagsandtheirofficiallanguages.④Givethestudentsanexample.⑤Startthegame.(Getstudentsfullyinvolvedinthecompetition.)【设计说明】学生分组竞赛，有利于充分调动学生参与的积极性。在团体荣誉感的驱策下学生们都跃跃欲试。游戏的规则比较简单，只要能率先说出相关的国家和语言，即可为所在的组得到相应的分数。教师也可变通，说出一项记一分，目的只有一个：让学生充分融入课堂。⑥Discussion(toarousethestudentstothinkmoreaboutlanguages)Drawthestudents’attentiononthefollowingfactthatsomecountrieshavemorethanoneofficiallanguage.Askthestudentstodiscussthepossiblean...
