单元：Unit3Tomorrow’sworld板块：Grammarandusage课堂设计指导思想：本节课是一节语法课。学习语法是为了运用。检查学生对语法的掌握情况，主要是看他们运用语法规则的能力，而不是解释语法现象的能力。所以，在平时的练习及测试中，要以实际运用为主，要让学生在语言交际中运用语法规则，在运用中逐步掌握语法规则。语法教学要注重精讲多练，重点突出，不必强求系统性、面面俱到。Teachingaims:1.Learnthebasicverbformsofthepassivevoiceandsomespecialpassivepatterns.2.Learnhowtousemodalverbsinthepassivevoice.3.Learnsomeverbsthatareoftenusedinthepassivevoice.Teachingprocedures:Step1Lead-in（PPTpage4-6，鼠标点击，显示图片、题目及答案）1.Reviewpassivevoicewithseveralpictures.(1)Theman_________(call)“Goodhusband”.(2)Thepetdog__________(treat)byveterinary.(3)Afrog__________(catch)byabigbirdjustnow.Answers(1)iscalled(2)isbeingtreated(3)wascaught2.Askstudentswhatthebasicformofthepassivevoiceis.（PPTpage7）Answerbe+done【设计说明】用生动形象的图片和动词填空，引入主题，复习被动语态的基本形式。Step2Thepassivevoice1.Helpstudentsreviewthetensesofthepassivevoice:(1)Simplepresenttense:am/is/are+done（PPTpage8，鼠标点击，显示be动词的变化）(2)Presentcontinuoustense:am/is/arebeing+done(3)Presentperfecttense:have/has+done(4)Simplefuturetense:shall/will+done(5)Simplepasttense:was/were+done（PPTpage9，鼠标点击，显示be动词的变化）(6)Pastcontinuoustense:was/werebeing+done(7)Pastperfecttense:hadbeen+done(8)Pastfuturetense:wouldbe+done2.Askstudentshowwecanchangeasentenceintothepassivevoice.Remindstudentsthatweshouldpayattentiontothefollowing:（PPTpage10，鼠标点击，逐条显示）(1)Findouttheobjectofthesentenceanduseitasthesubjectofthesentencewiththepassivevoice.(2)Decidethetenseofthesentenceandusetherelatedformofitspassive.(3)Ifnecessary,use“by”tojointheformersubject,whichshouldbeputintoitsobjectform.3.Askstudentswhenweusethepassivevoice.AskthemtoreadPoint3onpage48tofindtheanswer.Andgivethemthefollowingsentencesasexamples:（PPTpage11-12，鼠标点击，逐条显示）(1)不知道或没必要指出动作的执行者。Manyhouseswillbebuilthere.(2)强调动作的承受者。Thesong“TheEastisRed”waswrittenbyapoorpeasant.(3)动作的执行者有较长的修饰语。TheplanwassupportedbythosewhowishedtohavemorechancestospeakEnglish.(4)出于礼貌，不愿意说出动作的执行者。Youarerequestedtoattendthemeeting.4.AskstudentstoreadPoint3and4onpage48carefullyandcompletethefollowingpractice.Changethefollowingsentencesintothepassivevoice:（PPTpage13，鼠标点击，逐条显示）(1)Allofuslikeher.(2)Wearediscussingthequestion.(3)Wehaveputoffthemeeting.(4)Iwilldevelopmypicturenextweek.Answers(1)Sheislikedbyallofus.(2)Thequestionisbeingdiscussed.(3)Themeetinghasbeenputoff.(4)Mypicturewillbedevelopednextweek.Fillintheblankswiththerightformofthewordsgiven:（PPTpage14，鼠标点击，逐条显示）(1)I___________(give)anewbookbymyfatheronmybirthday.(2)English___________(find)veryuseful.(3)Thework______________(finish)tomorrow.(4)Theflowers______________(water)bythemnow.(5)Therailway________________(build)thistimelastyear.(6)Thenewway_______already_________(build).(7)Thenewrailway___________(build)bytheendoflastyear.(8)Hetoldmethesportsmeeting____________(hold)thenextmonth.(9)Rice___________(grow)inthesouthoftheStates.Answers(1)wasgiven(2)isfound(3)willbefinished(4)arebeingwatered(5)wasbeingbuilt(6)hasbeenbuilt(7)hadbeenbuilt(8)wouldbeheld(9)isgrown5.Askstudentstoreadthefourpiecesofinformationaboutthetopfourexhi...
