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_________?

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。

Unit9Whenwasitinvented?导学案

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

Athiefwascaughtlastnight.

Theywereaskedtospeakatthemeeting.

肯定式:Itwasmade.

否定式:Itwasnotmade.

疑问式:Wasitmade?No,itwasn’tYes,itwas

情境导入:warm-up

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。

4、拓展创新:

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。
