Do you feel like going for a swim?今天很热。你愿意去游泳吗?三、动词­ing形式作表语作表语的动词­ing形式包括现在分词和动名词。1现在分词作表语往往具有形容词的性质说明主语的性质、特征等。作表语的现在分词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movinginterestingencouragingexcitinginspiringboringsurprisingpuzzlingamusingastonishing ...这类分词有令人……的含义常修饰物。The argument is very convincing.这个论点很令人信服。Your speech is very interesting and encouraging.你的演讲很有趣而且很鼓舞人。2动名词作表语多表示抽象性的或习惯性的动作一般说明主语的内容。Her job is keeping the lecture hall as clean as possible.Keeping the lecture hall as clean as possible is her job.她的工作是尽量使报告厅保持干净。His job is painting walls. 他的工作是粉刷墙。His job is to paint the wall. 他的工作是粉刷这面墙。四、动词­ing形式作定语动名词和现在分词都可以作定语但有所区别。1动名词作定语表示被修饰词的某种性能或用途相当于for引导的介词短语。No one is allowed to speak aloud in the reading room.阅览室里不准大声说话。2现在分词作定语时它和被修饰词之间有逻辑上的主动关系表示所修饰词进行的动作相当于一个定语从句。The boy playing football on the playground is my younger brother.The boy that/who is playing football on the playground is my younger brother.在操场上踢足球的那个男孩是我的弟弟。[点津] 现在分词、过去分词和不定式作定语的一般区别:现在分词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。You should adapt to the changing situation.你应该适应不断变化的形势。The ground is covered with fallen leaves.地上满是落叶。Our school went on an organized trip last week.我们学校上周进行了一次有组织的旅行。I can't go with you, for I have a lot of work to do我不能和你一起去,因为我有许多工作要做。There's a note pinned to the door saying when the shop will open again.门上别着一张便条,上面写着商店什么时候再开门。五、动词­ing形式(现在分词)作宾语补足语动词­ing形式作宾语补足语时表示正在进行的动作或经常存在的状态。动词­ing形式常作以下动词的宾语补足语。1表示感觉和心理状态的感官动词(短语)(常见的有seehearfeelsmellfindnoticeobservelook atlisten to)sb.doing sth.(作宾语补足语)I felt somebody standing behind me.我感觉有人站在我后面。I saw the little boy crying there.我看到小男孩在那儿哭。2表示指使意义的使役动词(常见的有haveletkeepgetleave)sb./sth.doing sth.(作宾语补足语)We kept the fire burning all night long.们让火整夜燃烧着。I won't have you running about in the room.我不允许你在房间里跑来跑去。[点津] 使役动词接现在分词作宾语补足语表示……一直做某事。接不带to的不定式作宾语补足语表示让某人做某事;接过去分词作宾语补足语表示主语请某人做某事使完成某事或主语遭遇某事They use computers to keep the traffic running smoothly.他们用电脑使交通畅通。The old couple often take a walk after supper in the park with their pet dog following them.那对老夫妇晚饭后经常带着他们的宠物狗在公园散步。He had the walls painted this morning.他今天早上让人粉刷了墙。Tom's mother made him paint the house.汤姆的母亲让他油漆房子。Be careful, or you'll have your hands hurt.当心否则会弄伤手的。3用于with复合结构中。I couldn't do my homework with the noise going on.由于噪音不断我没法做家庭作业。With so many people looking at her, she felt nervous.这么多人看着她她感到紧张。I suddenly felt myself being hit by a heavy fist.我突然感到自己被重重地打了一拳。He wants to have his eyes examined tomorrow.他明天想去检查眼睛。We shouldn't keep our lights burning in the day.我们白天不应该开着灯。With all fans singing togetherhe felt so proud.所有的粉丝一起歌唱他感到如此的骄傲。六、动词­ing形式(现在分词)作状语的用法现在分词(短语)在句中作状语来修饰谓语动词或整个句子表示动作发生的时间、原因、条件、结果、方式、让步或伴随状况。1作时间状语(相当于一个时间状语从句)Walking in the park, she saw an old friend.When/While (she was) walking in the park, she saw an old friend.当她在公园里散步时她看到了她的一个老朋友。[点津]  当表示正在进行的动作时可直接在分词前面加上when/while此时也可理解为状语从句的省略。2作原因状语(一般可转换成由asbecause引导的原因状语从句)Being ill, he couldn't go to school.As he was ill, he couldn't go to school.因为生病了他无法去上学。3作条件状语(一般放在句首其前可以加ifunless等连词)Working hard, you'll make great progress.If you work hard, you'll make great progress.如果你努力工作你将取得很大进步。4作结果状语现在分词作结果状语时通常放在句末中间用逗号隔开表示一种顺其自然、意料之中的结果。The hospital has recently obtained new medical equipment, allowing more patients to be treated.这家医院最近得到一批新的医疗设备,这使更多的病人能得到治疗。[点津] 现在分词作结果状语是随着谓语动词的发生而产生的自然结果其逻辑主语往往是前面整个句子所描述的情况前面有时候可以加thus。而不定式作结果状语时常表示出乎意料的结果有时前面可以加only。试比较:He was caught in the rain, thus making himself catch a cold.被雨淋后他感冒了。I hurried to school, only to find it was Sunday.我匆忙赶到学校结果发现是星期天。5作让步、方式和伴随状语现在分词作让步、方式和伴随状语时说明动作发生的背景和情况。作伴随状语时表示分词的动作和主句的动作同时发生此时它可转换成并列句。Mary sat by the window of the classroom, reading a book.Mary sat by the window of the classroom and was reading a book.玛丽坐在教室的窗边读一本书。[点津] 为强调动词­ing形式表达的意义可在其前加上各种连词。例如加上whenwhile强调与谓语动词同时发生;加上beforeafter强调动作先后发生;加上thus强调结果;加上(al)though强调让步等。Though knowing all this, they made me pay for the damage.尽管他们了解这一切但还是让我赔偿损失。There is no greater pleasure than lying on my back in the middle of the grassland, staring at the night sky。没有什么比躺在草地中央,望着夜空更快乐的事了。Being poor, he can't afford a computer.因为穷,他买不起电脑。Newly­built wooden cottages line the street, turning the old town into a dreamland.新建的木屋沿着街道排列,把老城区变成了一个梦幻之地。七、动词­ing形式的时态和语态    语态时态    主动语态被动语态一般式doingbeing done完成式having donehaving been done1.现在分词的时态当现在分词的动作与谓语动词的动作同时发生时用分词的一般式;当现在分词的动作先发生而谓语动词的动作后发生时用分词的完成式。Walking in the street, I met an old friend of mine.我正在大街上行走时遇到了一位老朋友。(walking和谓语动词met同时发生)Having finished the letter, he went to post it.他写完信后就把它寄了出去。(having finished是先发生的went是后发生的)2现在分词的语态使用现在分词的主动式还是被动式这主要取决于现在分词和句子主语之间的关系。句子的主语就是分词的逻辑主语。Having been shown around the factory, they were very happy.(现在分词的被动式)被领着参观了工厂后他们很高兴。Having finished his homework, he went to bed.(现在分词的主动式)完成了作业后他上床睡觉。Seeing nobody at home, he decided to leave them a note.看到没人在家,他决定给他们留个便条。Having been told for several times, he still couldn't understand the rules.虽然被告诉了好几次,他还是不明白规则。Having received his reply, she rang him up.收到他的回信后,她给他打了电话。Being talked to, you should look into the eyes of the person.和别人说话时,你应该看着对方的眼睛。Having been asked to work overtime that evening, I missed a wonderful film.由于那天晚上被要求加班,我错过了一场精彩的电影。八、动词­ing形式的否定形式及动词­ing形式的复合结构1动词­ing形式的否定形式通常是在其前加not带有逻辑主语时 not应放在逻辑主语和动词­ing形式之间。You have no excuse for not going.你没有理由不去。He was punished for not having finished his homework.他因未完成作业而受到惩罚。2动词­ing形式复合结构由物主代词或人称代词宾格、名词所有格或普通格加动词­ingsb./sb.'sdoing构成。动词­ing形式的复合结构实际上是给动词­ing形式加了一个逻辑主语。动词­ing形式的复合结构有四种形式:形容词性物主代词+动词­ing名词所有格+动词­ing代词宾格+动词­ing名词+动词­ingHer coming to help encouraged all of us.她来帮忙鼓舞了我们所有人。The baby was made awake by the door suddenly shutting.这个婴儿被突然的关门声吵醒了。Can you imagine him/Jack cooking at home?你能想象他/杰克在家做饭的样子吗?无生命名词无论是作主语还是作宾语都不能用第种形式。Tom's winning first prize last year impressed me a lot.汤姆去年得了一等奖使我印象深刻。Do you mind my/me/Jack's/Jack leaving now?你介意我/杰克现在离开吗?Excuse me for my not coming on time很抱歉我没能按时来。His father's being ill made him worried.他父亲病了他很担心。We are looking forward to the singer's/the singer to give us a concert.我们盼望着这位歌手来给我们举办一场演唱会。Step 3: summary­ing作主语表示经常性、习惯性的动作有时可用形式主语it来代替。作宾语有些动词常接动词­ing形式作宾语有些动词即可接动词­ing形式又可接动词不定式作宾语意义不同。作表语现在分词作表语往往具有形容词的性质动名词作表语则常是说明主语的内容。作定语动名词作定语表示被修饰词的某种性能或用途;现在分词作定语时表示所修饰词进行的动作。作宾补感官动词、使役动词后及with复合结构中常用动词­ing形式作宾补。作状语表示动作发生的时间、原因、条件、结果、方式、让步或伴随状况其前可加连词whenunlessthough强调不同的意思。其他动词­ing形式有时态、语态的变化;否定形式是在其前加not;可有自己的逻辑主语。
