3、again.10.He went from door to door, (gather) waste papers and magazines.动词的-ing形式作定语和状语一、动词-ing形式作定语动名词作定语用来说明该名词的用途,不表示名词本身的动作;现在分词作定语与所修饰的名词具有逻辑上的主谓关系,即现在分词相当于所修饰名词的谓语。We must improve our working method. (动名词)我们必须改进工作方法。They set up an operating table in a small temple.(动名词)他们将手术台设在一座小庙里。China is a

4、 developing country. (现在分词)中国是发展中国家。The student making the experiment is our monitor.(现在分词)正在做实验的那个学生是我们的班长。动词-ing形式作定语时,应注意以下两点:(1)动名词短语不能作定语,单个的动名词可以用作定语,但仅作前置定语。working method = method for working 工作方法(2)单个现在分词和现在分词短语都可作定语,单个现在分词一般作前置定语,现在分词短语则作后置定语,相当于一个定语从句。the man visiting Japan=the man who is

5、 visiting Japan 访日的那个人二、动词-ing形式作状语的句法功能1.作时间状语(相当于一个时间状语从句)Hearing the knock on the door, they stopped talking. = When they heard the knock on the door, they stopped talking.听到有人在敲门,他们停止了谈话。2.作原因状语(相当于一个原因状语从句)Being ill, he didnt go to school yesterday. = As he was ill, he didnt go to school yester

6、day.因为生病了,昨天他没去上学。3.作伴随状语(动词-ing形式表示的动作与谓语动词表示的动作同时发生,相当于一个并列谓语)They stood there, waiting for the bus. = They stood there and waited for the bus. 他们站在那儿等公共汽车。4.作方式状语(相当于一个并列句)He died a glorious death, fighting the enemy for the people.=He died a glorious death, and he fought the enemy for the people

7、.他为了群众同敌人搏斗,光荣牺牲了。5.作结果状语(表示自然而然的结果,不定式短语作结果状语表示事与愿违的结果)Her husband died last year, leaving her with three children.她的丈夫去年去世了,撇下她和三个孩子。三、动词-ing形式的时态语态形式主动语态被动语态一般式doingbeing done完成式having donehaving been done1.动词-ing形式的一般式,可以表示没有时间先后顺序的动作,即没有明确过去、现在或将来的动作;一般式还可以表示发生在谓语动词之前的动作;有时也指发生在谓语动词之后的动作。I wish

8、 you would quit complaining.我希望你不再抱怨。(一般性动作)Chatting with each other, we enjoyed our dinner.我们边吃边聊。(与谓语同时发生)Most doctors strongly insist on giving up smoking and taking plenty of exercise.大多数医生强烈建议放弃抽烟并且多进行锻炼。(发生在谓语之后)2.动词-ing形式的完成式,表示动作发生在谓语动词之前。Having finished work, she got ready to go shopping. 完

9、成工作后,她准备去购物。Having been ill for two weeks, she felt rather weak. 由于病了两周,她感到身体很虚弱。四、动词-ing形式的否定式:not + 动词-ing。Not knowing this, he didnt come.他不知道这件事,所以没来。Not having made full preparations, we put off the sports meeting.因为没有做好充分的准备,我们把运动会延期了。五、部分动词-ing形式可以充当独立成分。这时句子主语与其无任何语法关系。常见的这样的动词-ing形式(短语)有:ge

10、nerally / strictly / exactly speaking大体 / 严格 / 准确说来judging from / by.根据判断talking of.谈到considering.考虑到;鉴于supposing(that).假设;假定regarding.关于六、动词-ing形式和动词-ed形式的区别1.语态不同:动词-ing形式表示主动概念,与其相关的名词或代词之间构成一种“主谓关系”;而动词-ed形式表示被动概念,与其相关的名词或代词构成一种“动宾关系”。a moving film一部感人的电影a moved girl一位受感动的姑娘a running machine一台转动

11、的机器a stolen car一辆被盗的汽车2.时间关系上不同:动词-ing形式表示正在进行的动作,或表示一个在现在或过去一段时间内经常性的动作; 动词-ed形式往往表示已完成的动作或是在以前某个未知时间发生的动作。a developing country发展中国家a developed country发达国家Hearing he won the first place finally, we all jumped with joy.听到他最终获得了第一名,我们都高兴地跳了起来。I dont like canned food.I prefer something fresh.我不喜欢吃罐装食品
