人教新版选择性必修二Unit1Discoverusefulstructures教学设计第2课时表语从句〔Predicativeclauses〕授课老师陈恒艳学校、班级高二课型语法时长40分钟教学设计理念本节语法课的设计主要是基于课堂教学以同学为主要中心的理念。活动设计遵循“发觉——归纳——练习——运用〞的思路。引导同学“自主探究式〞学习。通过活动让同学感知语法特点，学会分析及运用表语从句，引导同学发觉并总结语言规律。文本解读【What】选择性必修二第一单元Scienceandscientists中的DiscoverUsefulStructures是本单元的其次个课时，主要内容是学习“表语从句〞的用法。表语从句是在主从复合句中充当表语的从句。与宾语从句、主语从句一样，表语从句也是名词性从句中的一种。表语从句的引导词有【Why】该板块从认知，理解到运用。重点是让同学在语境中使用表语从句。【How】活动1旨在引导同学感知表语从句的结构特点并思索其表意功能。活动2让同学使用表语从句答复与课文相关的四个问题，使用目标结构重述熟识的信息，体会其意义和功能。活动3属于综合运用阶段，首先让同学使用引导词将对话一方David的话语(多为表语从句)补充完整，然后让同学把David的话语根据规律挨次复原到完整的对话语境中。该活动既强化了同学在语境中运用表语从句的力量，又培育了他们的文本分析和规律推理力量。。学情分析本节课授课对象是高二理科试验班的同学。本班同学英语根底参差不齐，少数同学英语根底较扎实，但大局部同学英语根底较差强人意，对语法学问只具备根本水平。课前本班同学已根本具备名词性从句有根本结构的认知，但还未详细了解表语从句。教学目标本节课是本单元第3个课时，设计如下：同学通过本课时的学习，能够：了解表语从句的用法;说明表语从句一些引导词的用法区分;在语境中正确使用表语从句。教学重难点教学重点：1.了解表语从句的用法;2.说明表语从句一些引导词的用法区分;教学难点：在语境中正确使用表语从句。教学资源PPT,黑板，多媒体教学目标活动形式与步骤活动意图活动层次学习效果评价时间创设情境导入主题Activity1Checkthehomework1.WhatwasitthatJohnSnowshowedtotheworld?〔JohnSnowshowedhowcholeracouldbeoveretotheworld.〕CANYOUMAKEUPTHEASKANDANSWERINTOAPREDICATAIVECLAUSE?〔WhatJohnSnowshowedtotheworldwashowcholeracouldbeovere.〕2.WhatwasSnow’sdiscoveryintwoparticularstreetsinLondon?〔Thecholeraoutbreakwassoseverethatmorethan500peoplediedintendays.〕Predictiveclause:〔SnowsdiscoveryintwoparticularstreetsinLondonwasthatthecholeraoutbreakwassoseverethatmorethan500peoplediedintendays.〕3.WhatwasSnowdeterminedtofindoutduringthe1854outbreakofcholerainLondon?〔Theoutbreakofcholerahadcausedover500deathswithintendays.〕Predictiveclause:〔WhatSnowwasdeterminedtofindoutwaswhytheoutbreakofcholerahadcausedover500deathswithintendays.〕4.Whatweretheexactplaces(Snowmarkedonthemap?)〔Allthosewhodiedhadlived/allthedeadpeoplehadlived.〕Predictiveclause:〔TheexactplacesSnowmarkedonthemapwerewherethecholeraoutbreakwassoseverethatmorethan500peoplediedintendays.〕5.WhatwasthefindingthatSnowannounced?〔Thewaterpumpwastoblameforthespreadofcholera/Thepumpwatercarriedcholeragerms/WaterfromtheBroadStreetpumphadbeeninfectedbywaste.〕Predictiveclause:〔Snow'sfindingwasthatthewaterpumpwastoblameforthespreadofcholera/thepumpwatercarriedcholeragerms/waterfromtheBroadStreetpumphadbeeninfectedbywaste.〕通过作业引入表语从句。让同学了解问答句式与表语从句的关系。A1感知与留意让同学提起对表语从句的爱好，并初步了解结构。3教学目标1Activity2Canyoufindoutthesentenceswithpredictiveclausesinthetextonpage2&3?Thenstatetheirmeaningandfunctions.1.Onetheorywasthatbadaircausedthedisease.2.Anothertheorywasthatcholerawascausedbyaninfectionfromgermsinfoodorwater.3.ThetruthwasthatthewaterfromtheBroadStreethadbeeninfectedbywaste.让同学发觉并总结表语的根本结构。A1感知与留意A2猎取与梳理同学能通过观看句子并立刻发觉飙英语从句的结构特征。2教学目标1Activity3Learnmoredetails什么是表语从句〔predictiveclause〕？Thequestioniswhowilldoit.Itseemsthatitisgoingtorain.Itlooksasifheisunhappytoday.在复合句中作_________的从句，叫作表语从句。它位于主句的____________之后，对主语进行解释、说明，使主语的内容详细化。〔表语；系动词〕附属连词that、whether(不能用if)that在从句中__________成分，that没有实际意义，不行省略；whether意为__________ExerciseMybeliefis_______Iwillsucceedbyworkinghard.我的信念是通过努力我会胜利。Themostpleasantthingoftherainyseasonis________onecanbeentirelyfreefromdust.雨季最令人开心的事情是完全没有灰尘。Theproblemis__________wecanfindthemthere.问题是我们能否在那里找到他们。〔不做；“是否〞；that;that;whether〕附属连词because、asif/thoughbecause：说明主语所表示的大事发生的缘由，意为________ExerciseHehasheartdisease.Thatis___________hehasbeensmokingtoomuch.他有心脏病。那是由于他抽烟太多。asif/though：从句表示的状况发生的可能性较小时常用______________ExerciseItseemsasifhe__________knowtheanswer.他好似不知道答案。〔由于；because；虚拟语气；didn’t〕连接代词who(ever)、whom(ever)、whose、what(ever)、which(ever)在从句中作主语、宾语、表语、定语ExerciseYoucanbe______________youwanttobe.你可以成为你想做的任何人。姆不再是过去的那个他了。〔whoever;what〕连接副词when、where、why、how在从句中作状语，表示时间、地点、缘由、方式等ExerciseThisis________Idon'tagreewithyou.这就是我不同意你的地方。Thequestionis_______wecangetintouchwithhim.问题是我们怎样才能和他联系上。Thatis_________Igotwetthrough.所以我才被淋湿了。(where;how;why)让同学深化学习表语从句的事实。A2猎取与梳理为后面的练习供应更好的学问储藏。3教学目标2Activity4Findthedifferencesthat与what的区分Thevillageisnolonger__________itusedtobe.这座村庄不再是过去的样子了。Thefactwas__________hehadforgottenaboutit.事实上，他已经把这件事忘了。(what;that)because与why的区分Thetrafficwassobad.That's_______Iwaslatethismorning.路上太堵了，所以我迟到了。Iwaslatethismorning.Thatwas________thetrafficwassobad.我今早迟到了，是由于路上太堵了。〔why;because〕让同学发觉并归纳不同引导词之间的的区分。B3内化与运用为后面同学运用引导词做好学问储藏。7教学目标2Activity5Showtime1．Thereasonforyourmistakeis_______youlackconfidenceinyourself.2．Thedoubtis_______hasgotawaywiththedocument.3．She'sbeenleadingthroughtherace,butitnowlooks_______she'stiring.4．Thebestmomentforthefootballstarwas_______hescoredthewinninggoal.5．WhatTom'sparentsreallydoubtis_______hewillrecoverfromtheseriousdiseasesoon.6．Everyyear,_______makesthemostbeautifulkitewillwinaprizeintheKiteFestival.7．Whatyourfatherwantstoknowis_______youaregettingonwithyourstudies.8．Myparentsareverykindtomeandalwaysletmedo_______IthinkIshoulddo.9．Youaresayingthateveryoneshouldbeequal,andthisis_______Idisagree.(that;who;asif;when;whether;however;how;what;where)强化对“表语从句〞的形式与意义的理解，并归纳它的使用规律。B3内化与运用同学能正确推断详细状况下所使用的引导词。3教学目标3Activity6PracticeincontextDavidistalkingtoMariaabouttheirscientificresearchproject.FirstpleteDavid'slines[AE],usingthewordsinthebox.Thenp
