Activity3Grammar一、动词-ing形式作定语1.现在分词形式作定语(1)单个现在分词作定语时，通常放在所修饰的名词之前。表示现在分词的动作正在进行，分词和所修饰的名词是逻辑上的主动关系。(2)现在分词短语作定语时，放在所修饰的名词之后。所修饰的名词是现在分词的逻辑主语，现在分词和逻辑主语之间是主动关系。此时相当于一个定语从句。(3)作定语的及物动词-ing形式为doing和beingdone。当被修饰的名词与现在分词之间为主动关系时，用doing；当被修饰的名词与现在分词之间为被动关系且表示动作正在进行时，用beingdone；作定语的不及物动词的现在分词只有doing。

【例句】◆Hespokeinalowvoiceinordernottowakethesleepingchild.为了不吵醒那个正在睡觉的孩子，他说话声音很低。◆Canyouseethestarmovinginthesky?你能看见那颗在天上移动的星星吗？◆Thefilmbeingshowninthecinemaisexciting.正在电影院上映的那部电影很令人激动。

【名师点睛】现在分词作定语，要注意现在分词所表示的动作发生的时间。一般说来，主要有下列两种情况：(1)表示正在进行的动作(变为定语从句时要用进行时态)。①Didyouseethegirldancingwithyourbrother.→Didyouseethegirlwhoisdancingwithyourbrother.②Thecomradesworkinginthecountrysidewillbebacktomorrow.→Thecomradeswhoareworkinginthecountrysidewillbebacktomorrow.

(2)表示经常性、习惯性动作或现在(当时)的状态(变为定语从句时多用一般现在时态或一般过去时态)。①Welivedinaroomfacingthesouth.→Welivedinaroomwhich/thatfacedthesouth.②Thefactorymakingthesepensisasmallone.→Thefactorywhich/thatmakesthesepensisasmallone.

2．动名词作定语动名词作定语用于说明被修饰词的用途、功能或目的，常放在被修
