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.Practice
Workon4a:
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.

教学目标:学习一般过去时的被动语态和特殊疑问句。
重难点:教学重难点:
一般过去时态的被动语态
基本结构:助动词be(was/were)+及物动词的过去分词

一、落实预习:见《助学》第133页翻译探究
教学操练1a,1c,2c
学生看书本上1a的图画,根据图画,把1a,1c,2c中的语言点综合起来,叫学生相互间回答问题。并用刚刚学到的目标句型来操练。最后,抽查几对学生,让他们在全班面前,按要求进行对话。
2)教学1b,2a,2b
首先,帮助学生明确本题的要求。接着,听力练习,学生根据录音内容完成1b,2aand2b.
最后,重放一遍录音内容,学生跟读。

1)计算机是何时发明的?
2)谁发明了计算机?
3)计算机是用来做什么?
4)你认为什么是最有用的发明?
5)它能够给人们更多时间工作和玩。
三精讲点拨典型例题解析:
1.--Whataniceclassroom!--It____everyday.
A.iscleaningB.hascleanedC.mustcleanD.iscleaned
解析:推测这句话的意思应该是“它每天都被打扫”,考查被动语态的结构be+动词的过去分词。因此答案应该选D。
2.IknowBeijingwell.I____therethreetimes.
A.willgoB.havebeenC.wentD.havegone
解析:推测这句话的意思“我很了解北京,我去过那三次”。表示去过应该采用的时态是现在完成时,因此可排除A和C,区别havebeen和havegone,havebeen去过;havegone去了(还没回来)。因此应该选择B。
中考连接:
1.--Lookatthesignontheright.--Oh,smoking____here.
A.doesn’tallowB.isn’tallowedC.didn’tallowD.wasn’tallowed
2.--Willyoucometothedinnerparty?--Iwon’tcomeunlessJim______.
A.can’tbeinvitedB.wasinvitedC.willbeinvitedD.isinvited
四归纳总结梳理知识:本单元主要学习了一般过去时的被动语态,包括其结构与用法。利用几项发明创造练习这一知识,最后用一篇小报告来完成写作练习。
