动名词的用法.doc

高中英语语法之动名词一、含义动名词兼有动词和名词特征的非谓语动词形式。基本形式为v-ing, 动名词具有名词的性质，因此在句中可以做主语、表语、宾语、定语等。动名词有时态和语态的变化。动名词的时态和语态的基本形式：（以write为例） 时态语态一般时完成时主动语态writinghaving written被动语态being writtenhaving been written注意：动名词的否定形式是：not writing 二、动名词的基本用法用作主语-常表抽象，或者泛指习惯性的动作。Smoking is bad for your health.Playing with fire is dangerous.Swimming is her favorite sport. 游泳是她最喜欢的体育运动。Learning is important to modern life. 学习对现代生活很重要。注意： 不定式也可以做主语。不定式与动名词作主语的区别：不定式作主语时经常表示具体的、一次性动作，而动名词作主语时经常表示抽象动作或习惯性动作。Getting up early is a good habit.To get up early this morning made me sleepy. 动名词作主语，有时用it作形式主语，把动名词置于句末。 It is no use/ good doing.(做。没有用); It is fun doing. (做。很有趣); It is a waste of time doing. (做。是浪费时间) 等句型中。例如：Its no use crying over spilt milk.(覆水难收）It is fun playing with children. 和孩子们一起玩真好。It is a waste of time persuading such a person to join us. 说服这样一个人加入我们当中来是浪费时间。2. 作宾语 作某些及物动词的宾语常见的动词有：advise，avoid，delay，escape，excuse，enjoy，consider，finish，deny，fancy，keep，mind（在乎）postpone，pardon，practise，suggest，imagine等。need，want，require后接动名词，表示被动意义。如： Would you mind opening the door？请你把门打开好吗？ Fancy meeting you here. 真想不到在这里遇见你。 作介词的宾语He left without saying good-bye to us. 他没有和我们道别就离开了。On arriving at the airport，I saw my mother standing in the crowd，waving to me. 一到机场，我就看见我母亲站在人群中，向我招手。 作某些词组的宾语常见的词组有：give up，go on，put off，cant help，cant stand，be worth，be devoted to，be accustomed to，be used to，object to； insist on，look forward to，be sure of，be keen on，be fond of，be good at，be tired of，be interested in，be afraid of, cannot help 情不自禁 be tired of 厌烦做某事 insist on 坚持 depend on/upon 指望，依赖 set about着手做get down to着手做 feel like 想要 lead to 导致等。pay attention to例： Im looking forward to having the summer holiday in Kun-ming. 我盼望去昆明度暑假。He gave up smoking several months ago. 几个月前，他戒烟了。 某些词组后接动名词作宾语时，可省略词组中的介词。常见的词组如下：He spends hours（in）reading newspapers everyday. 他每天花数小时阅读报纸。We mustnt waste time（in）arguing.我们不能浪费时间争论。The young doctor lacks experience（in）doing such kind of operation. 那年轻的医生在动这种手术上缺乏经验。We must stop/prevent the teens (from) smoking.我们必须阻止这些十多岁的孩子吸烟。We had a hard time（in）finding jobs. 我们一度找工作找得很苦。They earn a living（by）doing housework for other families.他们为别的家庭做家务来谋生计。他们讲英语（没）有困难。注意： 不定式也可以做宾语 I want to study English.

I want to stop to have a rest. 我很累。我想停下来休息一会。3. 作表语动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。表语动名词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。 Your task is cleaning the windows. 你的任务就是擦窗户。(Cleaning the windows is your task.) What I hate most is being laughed at. 我最痛恨的就是被别人嘲笑。(Being laughed at is what I hate most.) Teaching is my job.= My job is teaching. 我的工作是教书。 动名词作表语的时候，特别要注意：不要与正在进行时混淆。动名词作表语，表达的是“某件事”等。例如： his part-time job is promoting new products for the company. （动名词）他的业余工作是为那家公司推销新产品。Reading is for sure learning, but applying is also learning to a greater extent.（动名词）读书当然是学习，然而运用在很大程度上更是学习。Their task is exploring oil mines in the west. （动名词）4、作定语 动名词作定语的情况并不是很普遍，一般表示被修饰的词的用途和性能。例如： swimming pool 游泳池 reading material 阅读材料walking stick 手杖 a walking stick=a stick for walking=a stick which is used for walkinga washing machine=a machine for washing=a machine which is used for washinga reading room=a room for reading=a room which is used for reading三、动名词的逻辑主语（1）动名词的逻辑主语（动作的发出者）一般用名词所有格（s）或物主代词（my，your，his，her，our，their）充当。这种用名词所有格或物主代词动名词构成的形式叫复合结构。如：Would you mind my opening the door？我开门，你介意吗？Would you mind opening the door？请把门打开。第一句是让你去开门，第二句是我来开门。）（2）在口语中和非正式文体中常用人称代词宾格作动名词的逻辑主语。如：The doctor suggested them having their health check-up once a year. 医生建议他们每年检查一次身体。所以：你介意汤姆抽烟吗？Would you mind Tom/Toms smoking?你介意我抽烟吗？ Would you mind me/my smoking?Toms coming is what we have expected.His coming is what we have expected.She didnt mind Toms/ Tom coming here.She didnt mind his/ him coming here. 如果名词是表示无生命事物时，只用“名词的普通格(名词)+doing”，不用名词的所有格。Can you hear the noise of the machine running?你能听到机器运转的声音吗？四、动名词的否定形式由not加doing形式构成。His not coming made everyone present very disappointed.他没来使在场的每个人都很失望。6语法其实只是一些约定俗成的规则，多看几遍，记住就可以。就这么简单！
