[我的发现](1)动词-ing形式作定语的句子为_________。(2)动词-ing形式作表语的句子为_____。
要点突破动词-ing形式不能单独作谓语，没有人称和数的变化，但可以有自己的宾语和状语，还有时态和语态的变化。动词-ing形式由动词加-ing变化而成，它同时具有名词和动词的特征，在句中可以作主语、宾语、状语等。
Anyne wishing t try race walking shuld prbably first cnsult a cach. (动词-ing形式作定语)任何想竞走的人或许首先应该和教练商量一下。Learning English as a secnd language can be a painful experience. (动词-ing形式作主语)把英语当做第二语言来学是一个很痛苦的经历。The researchers had 100 vlunteers type the wrd“tuch”fur times using the smart keybard. (动词-ing形式作状语)研究人员让100名志愿者用智能键盘敲击单词“tuch”四次。
一、动词-ing形式作定语1．动词-ing形式作定语表属性、作用或用途表示名词的属性、作用或用途，作“供……用”讲，相当于介词fr短语，常置于被修饰的名词前。The answer is a big YES, if the air quality in yur camping area(＝the area fr camping) is gd.如果你露营地的空气质量很好，答案是一个大大的YES。They share a frnt dr and a washing machine.他们共同使用一个前门和一台洗衣机。
2．动词-ing形式(短语)作定语表示动作或状态动词-ing形式(短语)作定语表示所修饰词的动作或状态，被修饰词与动词-ing形式(短语)之间是逻辑上的主谓关系，相当于一个定语从句。单个的动词-ing形式作定语时，放在被修饰词前；动词-ing形式短语作定语时，则放在被修饰词后。
Race walkers mving at a pace f six miles per hur wuld burn abut 800 calries per hur.以每小时六英里的速度移动的竞走者每小时燃烧大约800卡路里。If yu are a teenager living in certain parts f the prvince, yu culd be eligible(符合条件) fr this prgram.如果你是生活在本省某些地方的青少年，你就可能符合这个项目的条件。
being dne表示正在进行的被动语态，作定语时，常用于被修饰词之后。Hi, Mm being shwn these days is really a gd mvie.这几天正在被放映的电影《你好，李焕英》确实是部好电影。
3．作定语的动词-ing形式，许多是由能够表示人们某种感情或情绪的动词变化而来的。常见的有：mving，interesting, encuraging, exciting, inspiring, bring，surprising, puzzling, amusing, astnishing, annying等，这类分词有“令人……的”的含义，常修饰物。Bacteria are an annying prblem fr astrnauts.对于航天员来说，细菌是一个令人恼火的问题。
动词-ing形式、过去分词和不定式作定语的区别动词-ing形式表示正在进行或习惯性的动作；过去分词表示被动或完成意义；不定式表示动作尚未发生。The prblem being discussed at the meeting is very imprtant. (表示动作正在进行)会上正在讨论的问题非常重要。
The prblem discussed at the meeting is very imprtant. (表示动作已经完成)会上讨论过的问题非常重要。The prblem t be discussed at the meeting is very imprtant. (表示动作将要发生)会上将要讨论的问题非常重要。

二、动词-ing形式作表语动词-ing形式包括动名词和现在分词，两者都可作表语，但有所区别。1．动名词作表语与主语通常是对等的关系，表示主语的内容，主语、表语可互换位置。What wrries me mst is her staying t late every night. (＝Her staying t late every night is what wrries me mst. )最使我担心的是她每天熬夜到很晚。My favurite sprt is swimming. (＝Swimming is my favurite sprt. )我最喜欢的运动是游泳。
2．现在分词作表语，表明主语的性质和特征，主语和表语的位置不可互换。The news is s exciting that we were excited at the news.这消息太令人兴奋了，我们听到这个消息都很振奋。
动名词(短语)与动词不定式(短语)作表语的区别动名词(短语)作表语表示抽象的、一般性的动作；动词不定式(短语)作表语表示一次具体的动作或将要发生的事。I have a gd friend whse hbby is painting.我有一个好友，他的爱好是画画。(一般性的动作)Tday what he wants t d is t paint.今天他想要做的事是画画。(具体的动作)
