海下景观LearningaboutLanguagezxxkw学科网学.科.网v.-ing形式的被动式用法非谓语动词是高中的重点语法，也是高考中的必考点，其中v.-ing形式的考查更是重中之重，分清v.-ing形式与其他非谓语动词用法及意义上的区别是学习v.-ing形式的关键。用v.-ing的适当形式完成下列句子，并指出所填部分在句中的作用。1.IhadalreadyheardthatGeorgedidn’tlike________________(等人).(_______)2.Aswedrewcloser,Icouldseeawhale_____________(被攻击)byapackofaboutsixotherkillers.(_______)beingkeptwaitingbeingattacked作宾语作宾补3.___________________(受伤严重)，thewhalesoondied.(_______)结论:以上所填部分均为v.-ing形式的_______。表示v.-ing形式的逻辑主语是该动作的承受者。Beingbadlywounded作状语被动式一、v.-ing形式的构成学科网﹡

Beingmadefunofbyothersinclassoftenmadetheboyveryangry.在班上经常被其他人取笑使得这个小男孩很生气。﹡Wearenotinterestedinthequestionbeingdiscussed.我们对正在讨论的问题不感兴趣。zxxkw二、v.-ing形式的被动式的句法功能1.作主语:﹡

Beingofferedsuchajobwasgoodluck.被给予这样一份工作是好运气。2.作动词、介词的宾语。﹡Themanworedarkglassestoavoidbeingrecognizedbythepolice.那人戴着墨镜以免被警察认出来。﹡ShelooksforwardtobeingtakentoHainanthisyear.她盼望着今年能被带到海南去。【名师点津】在want,need,require等动词表示“需要”时以及worth这个形容词后，要用v.-ing形式的主动形式表示被动含义。另外，在want,need,require表示“需要”时，也可以用不定式的被动式。﹡Myoldcomputerneedsrepairing.(=Myoldcomputerneedstoberepaired.)我的旧电脑需要修理。3.作定语:﹡Thelargebuildingbeingbuiltisanewlibrary.正在建设的大楼是一个新图书馆。【想一想】v.-ing形式的被动式作定语与过去分词和不定式的被动式作定语有什么区别？【拓展延伸】v.-ing形式的被动式表示一个被动的动作正在进行；过去分词表示一个被动的动作已经发生；不定式的被动式表示将来的一个被动的动作。ameetingbeingheldnow现在正在召开的会议ameetingheldyesterday昨天召开的一个会议ameetingtobeheldtomorrow明天将会召开的会议4.作宾语补足语:﹡IheardthispoembeingreadwhenIpassedbytheroom.当我经过这个房间时我听到有人在读这首诗。5.作状语:﹡

Havingbeensenttothewrongaddress,theletterdidnotreachher.由于那封信的地址投错了，所以她没有收到。1.(2009·陕西高考)Istillremember_______totheFamenTempleandwhatIsawthere.A.totakeB.tobetakenC.takingD.beingtaken【考点透析】考查非谓语动词及非谓语动词主动式与被动式的区别。(1)分析句子结构，确定用谓语动词还是非谓语动词。(2)明确非谓语动词在句中所作的成分。(3)确定用何种非谓语动词。(4)确定用该种非谓语动词的主动式还是被动式，一般式还是完成式。【思路分析】(1)句意:我仍记得被带着去过法门寺和在那里看到的一切。(2)句子中remember缺少宾语，而其后跟v.-ing形式作宾语。(3)句子中的主语I和take之间为动宾关系，故用v.-ing形式的被动式。(4)beingtaken为v.-ing形式的被动式，作remember的宾语。【易错分析】(1)totake为不定式的主动式，不能作remember的宾语，且句子主语I与take之间为动宾关系。(2)tobetaken虽为不定式的被动形式，但也不能作remember的宾语。(3)taking虽为v.-ing形式，但其为v.-ing形式的主动式，与句意不符。【答案】D。2.(2009·四川高考)_______manytimes,hefinallyunderstoodit.A.ToldB.TellingC.HavingtoldD.Havingbeentold【思路分析】(1)句意:给他讲了许多遍之后他终于明白了。(2)分析句子结构可知，句子的主语he与tell之间为动宾关系。(3)tell这一动作发生在谓语动作understand之前，故用其完成形式。(4)Havingbeentold为v.-ing形式的完成被动式，符合语境和句意。【易错分析】(1)Told为过去分词，表被动，但不能表明这一动作先于understand发生。(2)Telling为现在分词的一般式，表主动和进行，与句意不符。(3)Havingtold为现在分词的完成式，表主动，与句子和分词之间的逻辑关系不符。【答案】D。

通过对前面高考题的分析，同学们掌握了基本的做题思路了吗？请试着做下面的题目吧！3.(2010·浙江高考)Thetrafficrulesaysyoungchildrenundertheageoffourand_______lessthan40poundsmustbeinachildsafetyseat.A.beingweighedB.toweighC.weighedD.weighing【解析】选D。句意:交通法则规定四岁以下并且体重不超过四十磅的婴儿必须坐在婴儿安全座上。says之后为宾语从句。动词weigh与其逻辑主语children是主动关系，所以选择weighing。4.(2011·四川高考)_______animportantroleinanewmovie,Andyhasgotachancetobecomefamous.A.OfferB.OfferingC.OfferedD.Tooffer【解析】选C。考查非谓语动词。句意:在新电影中，安迪被给予了一个重要角色，获得了出名的机会。Andy与动词offer是逻辑上的动宾关系，所以用过去分词表被动，故选C。5.(2011·北京高考)It’simportantforthefigures________regularly.A.tobeupdatedB.tohavebeenupdatedC.toupdateD.tohaveupdated【解析】选A。考查非谓语动词作主语。句意:这些数据定期更新是很重要的。figures与update为动宾关系，故用被动结构，排除选项C和D。定期(regularly)更新为一般式动作，而不是先于某个动作发生，故不用不定式的完成式，排除B，故答案为A项。Unit3

本单元的写作要求是写一封投诉信。即在信中表达对某些人或事的不满。在日常生活中我们难免会产生不满情绪。因此要正确处理，学会“投诉”。投诉信与普通信件的不同在于:1.写作目的不同。投诉信主要针对未解决的问题提出投诉，强调自己的“不满”。2.写作方式不同。投诉信的目的在于希望得到对方的帮助，所以在写作方式上它倾向于在客观说明的基础上运用请求性的文字，以达到写投诉信的目的。
