一、V-ing形式作定语

假如句中V-ing形式用来单独修饰名词，则常前置（如：Thedancinggirlismyclassmate.）。假如修饰名词是V-ing短语，则该短语通常被放在其所修饰名词之后(如：Whoistheboyansweringtheprofessor’squestion?)。58/79在这两种情况下，V-ing形式或V-ing短语都能够改为定语从句。如：Thedancinggirlismyclassmate.可改为Thegirlwhoisdancingismyclassmate.二、V-ing形式作表语

V-ing形式作表语时，句子主语经常是“物”而不是“人”。变为V-ing形式动词经常是一些表示感情动词，如：interest,frighten,terrify,surprise,worry,excite,please等。59/79当句子被翻译成汉语时，常把V-ing形式译成“令人……”（如：a.ThestorytoldbyLiHuaisveryinteresting.b.Whenheisangry,hisfacegetsfrightening.）。三、V-ing形式作宾语补足语（如：a.Suddenlyheheardsomeoneknockinggentlyonthewindow.b.Theywatchedchildrenswimmingintheriver.）60/79

为了使句子意思完整，英语中有些及物动词后除了要求跟有宾语外，还要求跟有宾语补足语。宾语和宾语补足语一起被叫做复合宾语。用V-ing形式作宾语补足语，强调宾语补足语动作正在发生或延续。能接V-ing形式作宾语补足语动词有两类：一类是感官动词，如：feel,hear,see,notice,watch,observe,catch,find等；另一类是使役动词，如：have,get,leave,keep,start,send,set等。61/79四、V-ing形式作状语

V-ing形式或者V-ing短语作状语通惯用逗号把它和谓语动词分开，表示时间、原因、伴随情况等。1.表示“时间”。相当于由when,while等引导时间状语从句。有时连词when,while等能够保留使用（如：Whenwalkingalongthestreet,hemetLiuPing,hisoldschoolmate.）。62/792.表示“原因”。相当于由because,since,as引导原因状语从句(如：Beingpoor,thefathercan’taffordtosendhissontocollege.)。3.表示“条件”。相当于由if引导条件状语从句（如：Workinghard,you’llsucceed.）。4.表示“结果”。相当于一个结果状语从句，这时V-ing形式或V-ing短语常放在句子主干之后（如：Hiscarwasstuckinatrafficjam,causinghimtobelate.）。63/795.表示“让步”。相当于由“though/although/nomatter+疑问词”引导让步状语从句，这些连词有时保留使用（如：Havingwalkedsomanymiles,hesaidhewasn’ttiredatall.）。6.表示“伴随情况”。惯用V-ing形式普通式，置于句子后部，且有逗号分开(如：Thechildrenranoutoftheclassroom,talkingandlaughing.)。64/79【练习园地】依据汉语，用V-ing形式或V-ing短语完成以下句子（每空一词）。1.他边看报纸边吃早饭。Helookedthroughanewspaper____________________.2.假如你等一会儿，你可能会看见他。_______________________,you’llprobablyseehim.whilehavingbreakfast
