30、分词+其他.PaperwasinventedbyChinesepeopletwothousandyearsago.纸是中国人在二千多年前独创的。2 .否定句：主语+was/wcrcnot+及物动词的过去分词+其他.Womenwerenotallowedtotakepartinthegamesatfirst.起先妇女不允许参与奥运会。3 .一般疑问句：WaMWere+生语+及物动词的过去分诃+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.English

31、isspokenallovertheworld.全世界都在说英语，2 .须要突出或强调动作的承受者。c.g.Thisdictionaryisusedbymoststudcnls.这本字典是大多数学生在用的。三、主动语态变被动语态应留意的问题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.Themeetingwaspuloffbecauseoftheweather.会议因天气的原因被推迟了。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”的干脆宾语保留不变：假如把指物的

32、干脆宾语变为主语，则在间接宾语前加t。或forMyauntgavemeanc-dictionarjyesterday.1wasgivenane-dictionaryyesterday.Anc-Jictionarj,wasgiventomeyesterday.3 .主动句中感官动词see/hear/watch/feel等和使役动词makeethave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.Isawaheavymanenterthehouse.heavymanwasseentoenterthehouse.4 .系动词、不及物动词或某些短语动词(happen,lakeplace,

33、cometrue,fallasleep.)没有被动语态。WhathappenedtoMr.Brown?布朗先生发生了什么事？IV. Exercises练一练聘下列句子变为被动语态。1. Hechosesixstorybookstheotherday.Sixstor)booksbyhimtheotherday.2.

35、做题方法点拨示例：点拨：原句为一般过去时态，原句的谓语动词为SOId,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.点拨：分析原句的句子结构可知，“ole是谓语动词，mycamera是句子的宾语：改为被动语态句时，应将myCamCra作句子主语，谓语动词用wsstolen的形式。Somebodystolemycamerafromrnyhotelroom.Mycamerawasstolenfrommyhotelroom.学生们

36、自主将其他三个句子变成被动语态。3 .最终，老如与同学们一起校对答案，并对学生们有疑问的地方进行说明，或做出合理的分析点拨。Wherewerethesephotostaken?Wcwereadvisednottogooutalone.1hebookwastranslatedintodifferentlanguagesbydifferentwriters.Workon4b:Completethesentenceswithcorrectfb11softheverbsinthebox.1 .让学生们阅读方框中的词汇，了解词汇及句子的意思，为进行填词做好打算。cat.like,invite,tell,

38、tartedeatingabiscuitinscienceclass.5) Thecookiesbythehungrykidsinlessthan20minutes,andtheyreallythem.4 .最终，通读一遍全部句子，进行综合理解，看句子的意思是否通顺，合理。5 .CheektheanswerswiththeSs.1. wereinvited2.werebrought3. waslocked,rang（前一句中,去按门铃，是主动语态.）4. weretold,broke（前一句中,态：后一句中，RUby违反规则,5. wereeaten,liked（前-*句中,门是被锁的，故应用

39、被动语态：后一句中，我们学生们是被告知不要做这些事情，故应用被动语则是主动语态。）饼干是被孩子们吃掉了,故应用被动语态：后一句中，孩子们喜爱这些饼干，则是主动语态。）VI.PracticeWorkon4c:Decidewhetheractiveorpassiveformsshouldbeusedinthesesentences.Writethecocctformsintheblanks.1.先通读小短文，了解大意。Thetelephone(invent)byAlexanderGrahamBell.Hc(bom)in1847.Mr.Bell(work)ontheinventionofthetel
