课程基本信息学科英语年级高一学期春季课题必修二第五单元DiscoveringUsefulStructures教科书书名：普通高中英语教科书必修第二册出版社：人民教育出版社教学目标1.通过感知例句，发现并总结过去分词作表语和状语的语法功能和使用规律；2.通过填空、半句填空等练习在具体语境中辨析过去分词作表语和状语的不同用法，并能同过去分词作定语和宾补的情况加以区分。同时，能较好区分情绪类动词转换所得过去分词和现在分词的不同用法；3.通过调动已有知识和经验，发散创造性思维，积极运用动词过去分词描述自己最喜爱的歌手/音乐家，提升自身的语言表达和运用能力及思维品质；4.通过讨论学生最喜爱的歌手/音乐家来激发学生的讨论热情，让其在具体且实用的语境中灵活运用过去分词来描述他们最喜爱的歌手/音乐家以及他们对该歌手/音乐家的了解和看法。教学内容教学重点：引导学生发现并总结过去分词作表语和状语的语法功能和使用规律；2.帮助学生掌握过去分词做状语与状语从句之间的转换。教学难点：1.帮助学生掌握过去分词做状语的语法功能和使用规律；2.帮助学生过去分词做状语与状语从句之间的转换教学过程该板块的教材设计体现“感知—发现—总结—练习—运用”的学习过程。活动1要求学生观察句子，发现句中的过去分词，初步感知过去分词的功能。活动23要求学生使用过去分词改写句子，通过对比改写前后的句子，进一步感知过去分词的功能。活动4要求学生灵活运用目标结构，实现语境、语篇和语意的高度结合。因此，结合该单元阅读板块内容以及学生已学相关语法知识，设置以下教学过程：Step1Leadin&ExplorethestructuresSsareaskedtoanswerthequestionsrelatedtothereadingpassageintheunit.Instudents’answers,wordsthey’velearntinthepreviousreadingpassagewillbeshown.为了实现教学目标1，课堂导入环节教师通过提问与单元主篇阅读文章话题相关的问题，且设计的问题答案均源于阅读文本，不仅帮助学生回顾已学知识以及新单元词汇，同时通过填空的方式让学生先行做好学习过去分词新用法的准备。基于学生回答，结合话题图片，教师复现单元主课文的重点新学词汇，如energy,virtualchoir,opportunity,perform,ordinary等。同时，教师自然呈现目标语法结构(改编自课本p54Ex.1，并结合ReadingandThinking语篇内容)，让学生初步感知语言。具体句子如下：Q1:Whatisavirtualchoir?Avirtualchoirisonevideoonlinebyuploadingseveralvideos_________(perform)bydifferentpeopleonlineandputtingthemtogether.___________(upload)online,avirtualchoirisabinationofseveralvideos___________(perform)bydifferentpeople.Severalvideos___________(perform)bydifferentpeopleare__________(upload)ontotheInternetand________(put)togetherintoonevideotocreateavirtualchoir.Q2:Whocreatedthefirstvirtualchoir?_________(bear)intheUSAon2Jan.1970,Whitcarecreatedthefirstvirtualchoir.Q3:Whydidhedothat?Hewas__________(move)and________(inspire)byvirtualchoirbecauseitcouldbringenergytohim.Hefelt__________(excite)andenergeticeverytimehejoinedinavirtualchoir.Q4:Whatcouldavirtualchoirbringus?Thoughweareordinarypeople,_________(offer)anopportunitytoaddourvoicestothoseofotherindividuals,manyofusbenefitfromthevirtualchoir.Thevirtualchoirisawonderfulwaytogettheworld___________(change)tobeabetterplace.接着，教师引导学生同伴合作讨论，得出上述8个例句中过去分词的语法功能及使用规律。然后，教师带领学生一起分析并理清例句结构和意义：明确各句中过去分词形式充当的成分。最后学生通过思维导图自行整理归纳语法规则，使之印象深刻，从而落实教学目标1。值得一提的是，过去分词作表语和被动语态的形式是一样的，但是内涵却是不同的。过去分词作表语，强调主语的特点或所处的状态，此时过去分词往往是情绪类动词转换来的，相当于形容词，如excited；而被动语态中，主语是动词所表示动作的承受者。因此，在上述例句中，也设计了被动语态情况来帮助学生加以区分。如下图所示：二、然后教师引导学生根据上述例句分析过去分词作表语和状语的情况。状语：Uploadedonline,avirtualchoirisabinationofseveralvideosperformedbydifferentpeople.BornintheUSAon2Jan.1970,Whitcarecreatedthefirstvirtualchoir.Thoughweareordinarypeople,offeredanopportunitytoaddourvoicestothoseofotherindividuals,manyofusbenefitfromthevirtualchoir.由于以上三个例句中以上中红色标记的过去分词均充当状语，教师引导学生思考分别是什么状语。引导学生探究过去分词做状语与逻辑主语之间的关系：以上标红的过去分词和句子的主语是逻辑上的_被动_关系，表示_被动_或_完成_由此回顾状语从句的类别并进行过去分词做状语和状语从句的转换练习。此过程教师以时间状语的例子为例，向学生说明两点：1.过去分词做状语相当于一个状语从句。2.状从的省略：当主从句主语一致时，将从句的主语和be动词一起省略。其后，由学生进行自由创作，选择其中的一种状语造句（状语从句和对应的过去分词做状语）状语连接词例句转换成过去分词做状语时间状语when,as,after,before...Afterhewasacceptedbytheuniversity,hewasaddictedtoonlinegames.Acceptedbytheuniversity,hewasaddictedtoonlinegames.原因状语because,as,since...Becausetheyweregreatlymovedbythefilm,theyallcried.Greatlymovedbythefilm,theyallcried.条件状语ifIftheyaregrowninrichsoil,theseseedscangrowfast.Growninrichsoil,theseseedscangrowfast.伴随/方式状语andHewalkedupanddowntheroom,andhewaslostinthought.Hewalkedupanddowntheroom,lostinthought.让步状语though,althoughAlthoughtheyweredefeatedthistime,theycontinuedtoworkhard.Defeatedthistime,theycontinuedtoworkhard.由此，学生对于过去分词做状语的情况以及其和状语从句的转换就会有非常清晰的了解。此时，再让学生分析下述句子中过去分词分别充当什么状语来帮助学生巩固本节课所学。Uploadedonline,avirtualchoirisabinationofseveralvideosperformedbydifferentpeople.(伴随状语)BornintheUSAon2Jan.1970,Whitcarecreatedthefirstvirtualchoir.(伴随状语)Thoughweareordinarypeople,offeredanopportunitytoaddourvoicestothoseofotherindividuals,manyofusbenefitfromthevirtualchoir.(时间状语)Ex.Givenanotherhour,Icanalsoworkoutthisproblem._条件_状语Lostinthought,hedidn'thearthebell.___原因___状语Deeplymoved,sheacceptedthegift.___原因_______状语Sheacceptedthegift,deeplymoved.__伴随__状语Wounded,thebravesoldierscontinuedtofighttosearchforthetrappedintheruins.___让步___状语表语：SeveralvideosperformedbydifferentpeopleareuploadedontotheInternetandputtogetherintoonevideotocreateavirtualchoir.Hewasmovedandinspiredbyvirtualchoirbecauseitcouldbringenergytohim.Hefeltexcitedandenergeticeverytimehejoinedinavirtualchoir.教师引导学生总结过去分词做表语和被动语态的区别：过去分词作表语，强调主语的特点或所处的状态；而被动语态中，主语是动词所表示动作的承受者。1)Thisshopisnowclosed．这家商店现在已经关门了。(表语，表状态)2)Thisshopisclosedat6pmeveryday．这家商店每天6点关门。(被动语态，强调关门的动作)1)Thisnovelwaswrittenin1976.(被动语态，强调“写”的动作)2)Thisnoveliswellwritten.(表语,表示特征)三、学生整理思维导图：四、其后，为了检验学生对于动词过去分词形式表语和状语的语法功能的掌握情况，教师将本单元阅读语篇中出现的所有动词过去分词形式列出来。让学生加以区分。必要时学生可以选择进行小组内的讨论。教师根据实际情况进行引导。ThesevideosareuploadedontotheInternet,andthentheyareouttogetherintoonevideothatyoucanseeonlineavirtualchoir.(被动语态)Whitacre’snexteffortwastheVirtualYouthChoirforUNICEF,whichwasfirstseenonstageon23July2014intheUK.(被动语态)BornintheUSAon2January1970,WhitacrebeganstudyingmusicattheUniversityofNevadain1988.(伴随状语)Movedbythismusic,hesaid,“Itwaslikeseeingcolorforthefirsttime.”(伴随/时间/原因状语)Ins
