一、v.-ing形式作定语的位置1.现在分词(doing)作定语，可表示主动和动作正在进行，其被动形式(beingdone)通常表示被动的、正在进行的动作。2.现在分词作定语可转化为定语从句。3.现在分词作定语分为前置定语和后置定语：(1)单个现在分词作定语时，一般会放在被修饰的名词之前，说明被修饰名词的性质或特征等，构成前置定语。(2)现在分词短语作定语时，一定放在被修饰成分的后面，构成后置定语。例句：Heisanattackingplayer.他是一个攻击型的运动员。Alittlechildlearningtowalkoftenfalls.学走路的小孩常常摔跤。Doyouknowthenumberofpeoplecomingtotheparty?你知道来参加晚会的人数吗?当v.-ing形式作后置定语时，可以相当于相应的定语从句。Ayoungmanwritingnovelscametospeaktousyesterday.Ayoungmanwhowritesnovelscametospeaktousyesterday.一位写小说的年轻人昨天来向我们做报告。Thegirlsittingnexttomewasmycousin.Thegirlwhowassittingnexttomewasmycousin.坐在我旁边的姑娘是我表妹。二、v-ing形式作定语通常从以下三方面考查：1.说明被修饰词的性质、特征或用途。现在分词和所修饰的名词之间没有主谓关系，定语相当于一个介词for引导的短语。Theysetupanoperatingtable(=atableforoperating)inasmalltemple.他们将手术台架设在一座小庙里。Hemaybeinthe

readingroom(aroomforreading).他可能在阅览室里。2.与被修饰词为主动关系且表示正在进行的动作无论现在分词作前置定语还是后置定语，在逻辑上与所修饰的名词之间为主谓关系，都可改成定语从句。Therewereabout200childrenstudying(whowerestudying)intheartschool.有大约两百个孩子在这所艺术学校学习。Whoisthetalkingwoman(whoistalking)overthere？正在那边说话的那位妇女是谁?3.有些，v-ing形式已经转化成形容词，常作定语，用来修饰物，表示“令人……”。这类词也可以转换成定语从句。常用的此类词有:exciting，amusing，amazing，astonishing，shocking，puzzling，confusing，disappointing，discourging，pleasing,striking,boring,tiring，touching，moving，interesting，satisfying，terrifying，frightening等。Thatmusthavebeenaterrifyingexperience.那一定是一段可怕的经历。（2022·北京高考）Forinstance,wemustexercisedailyregardlessofourageandworkingstyle.例如，无论我们的年龄和工作方式如何，我们都必须每天锻炼。三、如果v-ing形式与被修饰词是被动关系，就用它的被动式，即beingdone作定语。beingdoing通常表示正在被做，常作后置定语。Thetallbuildingbeingbuiltnowisournewschool.建设中的高楼是我们的新学校。Thequestionbeingdiscussedwaspresentedbytheheadmaster。讨论中的问题是校长提出的。Summary

现在分词作定语构成基本用法基本形式v-ing变形:beingdonehavingdonehavingbeendone1.单个现在分词作定语，置于被修饰词前，叫前置定语。2.现在分词短语作定语，置于被修饰词后，叫后置定语。3.现在分词短语作后置定语，可转换为定语从句。Exercise.Ⅰ改写短语1.the___________room=theroomformeeting2.a____________stick=astickforwalking3.anembarrassingquestion=question____________________4.asleepingchild=achild_________________________________5.alisteningchild=achild___________________________Ⅱ.句型转换1.TheyoungmansittingbetweenJohnandMarywastheeditorofthecampusnewspaper.meetingwalkingwhichisembarrassingwhoissleepingwhoislistening→Theyoungman_________________________________betweenJohnandMarywastheeditorofthecampusnewspaper.2.ThemanstandingattheschoolgatewasProfessorHua.→Theman_________________________attheschoolgatewasProfessorHua.3.ThebikewhichisbeingrepairedbelongstoMrSmith.→Thebike__________________belongstoMrSmith.who/thatwassittingwho/thatwasstandingbeingrepaired4.Thetopicbeingdiscussedisaboutenvironmentalproblems.→Thetopic________________________________isaboutenvironmentalproblems.5.Iliketowatchtheleaveswhichare
