生们完成填空试题后，可以打开课本检查答案，对错误的句子，单独进行强化记忆。Ⅲ.Grammar一般过去时态的被动语态的构成英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。如：Wecleanedtheclassroomyesterday.我们昨天打扫了教室。(主动语态，主语we是clean这一动作的执行者)Theclassroomwascleanedyesterday.教室昨天被打扫。(被动语态，主语theclassroom是clean这一动作的承受者)一、一般过去时被动语态一般过去时被动语态的结构为“主语+was/were+及物动词的过去分词(+by+动作的执行者).”。如：Treeswereplantedlastspring.去年春天种了树。1.肯定句：主语+was/were+及物动词的过去分词+其他.PaperwasinventedbyChinesepeopletwothousandyearsago.纸是中国人在二千多年前发明的。2.否定句：主语+was/werenot+及物动词的过去分词+其他.Womenwerenotallowedtotakepartinthegamesatfirst.开始妇女不允许参加奥运会。3.一般疑问句：Was/Were+主语+及物动词的过去分词+其他?Werethesepicturesdrawnbyyoursister?这些图片是由你妹妹画的吗？二、被动语态的用法：1.不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。e.g.Englishisspokenallovertheworld.全世界都在说英语。2.需要突出或强调动作的承受者。e.g.Thisdictionaryisusedbymoststudents.这本字典是大多数学生在用的。三、主动语态变被动语态应注意的问题1.有些短语动词相当于及物动词，变为被动句时介词或副词不能去掉。Theyputoffthemeetingbecauseoftheweather.Themeetingwasputoffbecauseoftheweather.会议因天气的缘故被推迟了。2.含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指物”的直接宾语变为主语，则在间接宾语前加to或for。Myauntgavemeane-dictionaryyesterday.Iwasgivenane-dictionaryyesterday.Ane-dictionarywasgiventomeyesterday.3.主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。Isawaheavymanenterthehouse.Aheavymanwasseentoenterthehouse.4.系动词、不及物动词或某些短语动词（happen,takeplace,cometrue,fallasleep…）没有被动语态。WhathappenedtoMr.Brown?布朗先生发生了什么事？Ⅳ.Exercises练一练将下列句子变为被动语态。1.Hechosesixstorybookstheotherday.Sixstorybooks____________byhimtheotherday.2.UncleLeegaveJackalargecakeforhepaintedthewallwonderfully.Jack___________alargecakeforhepaintedthewallwonderfully.3.Amouseatehalfofthecakelastnight.Halfofthe_________byamouselastnight.将下列句子变为主动语态。4.WerethesemachinesinventedbyEdison?_______Edison_______thesemachines?5.ThepostcardwassenttoLindabyPaul.Paul_______thepostcard_______Linda.6.AmericawasdiscoveredbyColumbus._______Columbusdiscovered_________?Ⅴ.PracticeWorkon4a:1.TellSstoreadthesentencesin4aandrewritethesentencesusingthepassivevoice.2.做题方法点拨示例：①点拨：原句为一般过去时态，原句的谓语动词为sold，宾语为thefridge；改为被动语态时，应将thefridge作主语，谓语动词用wassold的形式。Theysoldthefridgeatalowprice.→Thefridgewassoldatalowprice.②点拨：分析原句的句子结构可知，stole是谓语动词，mycamera是句子的宾语；改为被动语态句时，应将mycamera作句子主语，谓语动词用wasstolen的形式。Somebodystolemycamerafrommyhotelroom.→Mycamerawasstolenfrommyhotelroom.学生们自主将其他三个句子变成被动语态。3.最后，教师与同学们一起校对答案，并对学生们有疑问的地方进行解释，或做出合理的分析点拨。Wherewerethesephotostaken?Wewereadvisednottogooutalone.Thebookwastranslatedintodifferentlanguagesbydifferentwriters.Workon4b:Completethesentenceswithcorrectformsoftheverbsinthebox.1.让学生们阅读方框中的词汇，了解词汇及句子的意思，为进行填词做好准备。eat,like,invite,tell,lock,ring,break,bring2.认真阅读每个句子，根据上下文确定空格处应填的意思。3.逐句进行分析推敲，然后分析句子的时态及语态，用适当的形式填空。1)You____________tothepartylastnight,weren’tyou?Whydidn’tyougo?2)Theearthquakehappenedallofasudden,butluckilythevillagers_____________toasafeplace.3)Thedoor___________whenwearrived,sowe______thebell.4)Thestudents___________nottoeatordrinkinclass,butRuby______therulewhenshestartedeatingabiscuitinscienceclass.5)Thecookies__________bythehungrykidsinlessthan20minutes,andtheyreally_____them.4.最后，通读一遍所有句子，进行综合理解，看句子的意思是否通顺，合理。5.ChecktheanswerswiththeSs.1.wereinvited2.werebrought3.waslocked,rang(前一句中，门是被锁的，故应用被动语态；后一句中，我们去按门铃，是主动语态。)4.weretold,broke(前一句中，学生们是被告诉不要做这些事情，故应用被动语态；后一句中，Ruby违反规则，则是主动语态。)5.wereeaten,liked(前一句中，饼干是被孩子们吃掉了，故应用被动语态；后一句中，孩子们喜欢这些饼干，则是主动语态。)Ⅵ.PracticeWorkon4c:Decidewhetheractiveorpassiveformsshouldbeusedinthesesentences.Writethecorrectformsintheblanks.1.先通读小短文，了解大意。Thetelephone______________(invent)byAlexanderGrahamBell.He__________(born)in1847.Mr.Bell________(work)ontheinventionofthetelephonewithThomasWatson.In1875,Mr.Bell_________(learn)howtosendmusicalnotesthroughaninstrumentsimilartoatelephone.Finally,thetelephone_____________(invent)in1876.Thefirstsentencethat_________(say)onthetelephonebyMr.Bellwas“Mr.Watson,comehere;Iwanttoseeyou.”Todaythetelephone________(use)aroundtheworld.2.逐句分析每一句话的意思，确定句子主语和谓语动词之间主动或被动关系。3.结合句子的时态，填上正确的形式。4.复读短文，看是否通顺。5.ChecktheanswersHomework补全下列主动句变被动句。1.Jennyputherclothesinthesuitcaselastnight.Herclothes________inthesuitcaselastnight.2.ThetwinssanganEnglishsongthatday.AnEnglishsong____________bythetwinsthatday.3.Didtheybuildabridgehereayearago? ____abridge____herebythemayearago?4.Theysoldoutthelightgreendressesyesterday.Thelightgreendresses______________out.SectionB1(1a-2e)一、教学目标：1.语言知识目标：1)能掌握以下单词：crispy,salty,sour,bymistake,customer,theOlympics,Canadian,divide,divide…into,basket,popularity,lookupto,hero,professional2)能掌握以下句型：①Potatochipswereinventedbymistake.②ItisbelievedthatthefirstbasketballgameinhistorywasplayedonDecember21,1891.③Dr.Naismithdividedthemeninhisclassintotwoteamsandtaughtthemtoplayhisnewgame.④Atthesametime,theyneedtostopthecompetingteamfromgettingtheballintotheirownbasket.⑤Thesestarsencourageyoungpeopletoworkhardtoachievetheirdreams.2.情感态度价值观目标：了解世界上一些对人类有着重大意义的发明的相关信息，开阔学生的眼界，养成勤于思考，善于发现的好习惯，培养学生的创造精神。二、教学重难点1.教学重点：1)掌握本课时出现的生词及用法。2)进行听力训练，提高综合听说能力。3)阅读短文，获得相关信息，提高学生们的综合阅读能力。2.教学难点1)听力训练2)阅读2b部分的短文并完成相关要求。三、教学过程Ⅰ.Warmingup1.LetSswatchaninterestingpicture.2.Asksomequest
