SectionⅢDiscoveringUsefulStructures过去分词作定语和宾补1.(教材P41)Theyhadcastlesbuilt(build)allaroundEngland,andmadechangesto

thelegalsystem.2.(教材P42)Theyusethesameflag,known(know)astheUnionJack,...3.(教材P42)JudyandIhadourcarparked(park)inanundergroundcarparkne

arTrafalgarSquare,wherewecouldgetourcarbatterycharged(charge).过去分词作定语时的意义1.及物动词的过去分词作定语,在语态上表示被动;在时间上,常表示动作已经发生或完成,有时也不表示时间性。◆Ourteacherwatchedus

doingtheexperimentandgaveusasatisfiedsmileatlast.我们的老师看着我们做实验,最后给了我们一个满意的微笑。◆Theplanputforwardatthemeetingwillbecarriedout

soon.会上提出的计划将很快被执行。2.不及物动词的过去分词作定语,它不表示被动意义,只强调动作完成。◆Manylittlekidslikegatheringfallenleavesintheyard.许多小孩子喜欢在庭院里收

集落叶。◆Therisensunisshiningbrightlyinthemorning.早上已升起的太阳正明亮地闪耀着。【典例1】(2019·北京卷)EarthDay,____________(mark)on22April,isanannualeventaimingt

oraisepublicawarenessaboutenvironmentalprotection.解析:句意:地球日在4月22日举行,是一项旨在提高公众环保意识的年度事件。mark在这里是“庆祝,纪念(重要事件)”之意,是及物动词,EarthDa

y与之是被动关系,此处的字面意思是“地球日在4月22日被庆祝”,故用过去分词短语作定语。答案:marked过去分词作定语时的位置1.前置定语一般情况下,单个过去分词作前置定语,即放在所修饰词之前。◆Thepolluted

waterwastoblameforthespreadofcholera.被污染的水造成了霍乱的传播。◆Weneededmuchmorequalifiedworkers.我们需要更多的合格的工人。有些过去分词表示特定含义时,单独作定语也可放在所修饰的

名词之后,如left(剩余的),given(所给的),concerned(有关的)等。◆Therearefewtigersleft.Itistimeforthedepartmentsconcernedtotakemeasur

estoprotectthemfromdyingout.剩余的老虎不多了,是相关当局采取措施保护它们免遭灭绝的时候了。2.后置定语过去分词短语作定语时往往作后置定语,即放在所修饰词之后,它的作用相当于一个定语从句。◆Heisateacherlovedbyhisstu

dents.他是一位受学生爱戴的老师。◆Thebookpublishedtenyearsagoisstillabest-sellertoday.十年前出版的这本书现在仍然是一本畅销书。3.过去分词与现在分词作定语的区别意义形式语态时态过去分词

被动完成现在分词主动进行◆Asweallknow,Chinaisadevelopingcountry.众所周知,中国是一个发展中国家。◆Thevisitorisfromadevelopedcountry.这位游客来自一个发达国家。4.过去分词(done)、

现在分词的被动语态(beingdone)与动词不定式的被动语态(tobedone)作定语的区别意义形式语态时态done被动完成beingdone被动进行tobedone被动尚未发生◆Thebuildingbuiltlastyearisourclassroombuilding.

去年建造的那栋楼是我们的教学楼。◆Thebuildingbeingbuiltnowisourclassroombuilding.现在正在建造的那栋楼是我们的教学楼。◆Thebuildingtobebuiltnextmonthisourclassroombuilding.下个月将要建造的那栋楼是我们

的教学楼。常见的过去分词作宾语补足语的情况1.过去分词用在表状态的动词keep,leave等词的后面作宾语补足语。◆Hepassedaway,leavinghisworksunfinished.他去世了,留下他的著作还未完成。◆Don’tkee

pyourmouthshutwhenIaskyouaquestion.当我问你问题时不要闭口不语。2.过去分词用在使役动词have/get和make的后面作宾语补足语。(1)“have/get+宾语+过去分词”表示“让别人做某事”。◆Hewantstohave/

gethiseyesexaminedtomorrow.他明天想去检查眼睛。◆JennyhopesthatMr.SmithwillsuggestagoodwaytohaveherwrittenEnglishimprovedinashortperiod.珍妮希望史密斯先生会建

议一个好的方法以使她的英语写作在短期内得到提升。(2)在“make+宾语+过去分词”这种结构中,过去分词表示结果。◆TheymanagedtomakethemselvesunderstoodbyusingverysimpleEnglish.他们用很浅易的英语来设法使自己被理解。

3.感官动词see,hear,notice,observe,watch,feel,find等后,可用过去分词作宾语补足语。◆Whenwesawtheroadblockedwithsnow,wedecidedtospendtheholidayathome.当我们看到道路被雪封住后,我

们决定在家过假期。◆Thenextmorningpeoplefoundtheworldoutsidetheirhousescompletelychanged.第二天早上,人们发现他们房子外面的世界全变了样。4.表示“意愿;命令”的动词,如like,want

,wish,expect,order等可用过去分词作宾语补足语。◆Themanagerorderedtheworkfinishedattheendofthisweek.经理要求在本周末完成这项工作。5.过去分词用在“with+宾语+宾补”这一结构中,过去分词与宾语之间是动宾关系。◆Wi

theveryproblemsettled,hebegantothinkofajourney.每一个问题解决后,他开始考虑旅行。【典例2】(2018·天津卷)IneedanewpassportsoIwill

havetohavemyphotograph____________(take).解析:句意:我需要一个新护照,因此我得照张相。本题考查非谓语动词作宾语补足语。宾语myphotograph与take之间为被动关系,且表示让他人去做这件事,因此用过去分词作宾补。答案:taken非谓语动词作宾语补足语

的区别1.感官动词(短语)see,watch,observe,lookat,notice,hear,listento,feel等的宾语补足语主要有三种形式,试比较(以hear为例):hear+宾语+doingsth.听到„„正在做„„,(主动、进行)dosth.听到„„

听见她正在唱一首英文歌。(主动、正在进行)◆IheardhersinganEnglishsongjustnow.刚才我听见她唱了一首英文歌。(主动、完成)◆TolearnEnglishwell,weshouldfindopportuni

tiestohearEnglishspokenasmuchaspossible.为了学好英语,我们应该尽可能多地听英语。(被动、无时间性)2.使役动词make,have,get,keep后加复合宾语的比较:(1)make+宾语+dosth.让

„„做某事(主动)done让„„被做(被动)◆Theshockingnewsmademerealizewhatterribleproblemswewouldface.这令人震惊的消息使我意识到我们将面临多么可怕的问题。◆Hespokeslowlyandclearlysot

hathecouldmakehimselfunderstood.他说得又慢又清楚以便使自己被理解。(2)have+宾语+dosth.使„„做某事(主动)doingsth.使„„持续做某事(主动、进行)done使„„被做(被动)◆Motherhadmegototheshopandbuys

ityHallinHarvardYard,anditisperhapstheUniversity’sbestknownlandmark.解析:句意:今天,你可以在哈佛广场的大学礼堂前找到一尊站立着的JohnHarvard的雕

像,这也许是这所大学最著名的地标。astatueofJohnHarvard和动词stand之间为逻辑上的主谓关系,故用现在分词作宾语补足语。答案:standingⅠ单句语法填空1.Weseeanoldmansweepingthefallen(fall)lea

oosoon!【解题导语】本文是一篇说明文。加拿大魁北克市冬季降雪量会达到三米。不过,别担心,这儿有丰富多样的冬季户外运动。1.slightly解析:考查副词。设空处修饰形容词worried,表示“稍微”,故填副词slightly。2.what解析

:考查连接词。设空表示“我无法想象降雪量达到三米是什么样的情景”,故填what。what在此引导宾语从句。3.A解析:考查不定冠词。由下文的描述可知,此处表示“有许多新的运动”,故填A。anumberof意为“许多,大量”。4.arriving解

析:考查动词-ing形式作宾语的用法。设空处作介词Before的宾语,故填arriving。5.types解析:考查名词复数。设空处表示“种类”,因为type是可数名词,由其前的were和different可知,此处应用其复数形式,故填types。6.covered解析:

考查过去分词作定语的用法。设空处表示“被积雪覆盖的山”,cover与mountain之间是动宾关系,故填covered。7.exciting解析:考查形容词作定语的用法。设空处作定语修饰sport,表示“令人激动的”,故填形容词exciting。8.which解析:考查关系代词。设空处引导非限制

性定语从句补充说明lake,且在从句中作主语,故填which。9.wascancelled解析:考查一般过去时的被动语态。设空处表示“有一次因为大暴雪学校还放了假”,school与cancel之间是被动关系,因为设空处表示的动作发生在过去,应用一般过

去时,故填wascancelled。10.so解析:考查副词。so...that...意为“如此„„以至于„„”。
