我的非谓语动词.ppt

第8讲 非谓语动词,非谓语动词是指在句子中不是作谓语的动词，主要包括不定式、动名词和分词（现在分词和过去分词），即动词的非谓语形式。非谓语动词除了不能独立作谓语外，可以承担句子的其它任何成分。,什么是非谓语动词？,非谓语动词与谓语动词的相同点?,（1）如果是及物动词都可接宾语，例如：,The suit fits him very well.The suit used to fit him very well.,They built a garden.They suggested building a garden.,（2）都可以被状语修饰，例如：,（3）都有主动与被动、“体”式（一般式；进行式；完成式）的变化，例如：,2,Having written the composition,we handed it in.（现在分词的完成式）,We have written the composition.（谓语动词的完成时）,He avoided being punished by his parents.（动名词的被动式）,He was punished by his parents.（谓语动词被动语态）,（4）都可以有逻辑主语，例如：,2,We being League member,the work was well done.（现在分词的逻辑主语）,We are League members.（谓语动词的主语）,The boss ordered them to start the work.（动词不定式的逻辑主语）,They started the work at once.（谓语动词的逻辑主语）,非谓语动词与谓语动词的不同点？,（1）非谓语动词可以有名词作用（如动词不定式和动名词），在句中做主语、宾语、表语。,（4）谓语动词在句中作谓语，受主语的人称和数的限制；非谓语动词在句中不能单独作谓语，它不受主语的人称和数的限制。,（3）非谓语动词可以有副词作用（如动词不定式和分词），在句中作状语。,（2）非谓语动词可以有形容词作用（如动词不定式和分词），在句中做定语、表语或宾语补足语。,(一)动词不定式肯定式：（to）+do；动词不定式否定式：not+(to)do；动词不定式具有名词、形容词、副词的特征。,动词不定式的不同形式？,（1）一般式：不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后。例如：Im glad to meet you.He seems to know a lot.We plan to pay a visit.He wants to be an artist.The patient asked to be operated on at once.The teacher ordered the work to be done.,（2）进行式：不定式的进行式所表示的动作与谓语动词动作同时发生，例如：The boy pretended to be working hard.He seems to be reading in his room.,4,（3）完成式：不定式的完成式表示的动作发生 在谓语动词动作之前，例如：I happened to have seen the film.He is pleased to have met his friend.,（1）作主语：To finish the work in ten minutes is very hard.To lose your heart means failure.,不定式的句法功能？,动词不定式短语作主语时，常用it作形式主语，真正的主语不定式置于句后，例如上面两句可用如下形式：It is very hard to finish the work in ten minutes.It means failure to lose your heart.常用句式有：1、It+be+名词+to do sth.2、It takes sb.+some time+to do sth.,3、It+be+形容词+of sb.+to do sth.常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等表示赞扬或批评的形容词，不定式前的sb.作其逻辑主语。如：It is very kind of you to say so.,5,4、It+be+形容词+for sb.+to do sth.,例如：,Its impossible for me to finish the work in 10 minutes.,（2）作表语，例如：,5,Her job is to clean the hall.He appears to have caught a cold.,（3）作宾语，例如：,5,常与不定式做宾语连用的动词有：want,hope,wish,offer,fail,plan,learn,pretend,refuse,manage,help,agree,promise,prefer等；,He refused to do that job.She agreed to marry him.,如果不定式（宾语）后面有宾语补足语，则用it作形式宾语，真正的宾语（不定式）后置，放在宾语补足语后面，例如：Marx found it important to study the situation in Russia.,注：动词不定式也可充当介词宾语，如：I have no choice but to stay here.He did nothing last Sunday but repair his bike.,5,动词不定式前有时可与疑问词连用，如：He gave us some advice on how to learn English.,（4）作宾语补足语：在复合宾语（宾语+宾补）中，动词不定式可充当宾语补足语，如下动词常跟这种复合宾语：want,wish,ask,tell,order,beg,permit,help,advise,persuade,allow,prepare,cause,force,call on,wait for,invite等等.,5,注：A.介词有时也与这种复合宾语连用，如：With a lot of work to do,he didnt go to the cinema,5,B.一些使役动词make，let，have（表示“让、使”）和感官动词see，watch，look at，observe，notice，hear，listen to，feel（这些动词亦可总结为口诀：“三使五看两听一感觉”）等后接不带to的不定式作宾补，但改为被动语态时，不定式要加to,如：I saw him cross the road.He was seen to cross the road.,（5）作定语：动词不定式作定语，放在所修饰的名词或代词后。与所修饰名词有如下关系：动宾关系：I have a meeting to attend.,5,注意：A.不定式为不及物动词时，所修饰的名词如果是地点、工具等，应有必要的介词，如：He found a good house to live in.The child has nothing to worry about.What did you open it with?,5,B.但如果不定式修饰time,place,way，可以省略介词：He has no place to live.This is the best way to work out this problem.,C.如果不定式所修饰名词是不定式动作承受者，不定 式可用主动式也可用被动式：Have you got anything to send?Have you got anything to be sent?,第一句逻辑上是you send anything;第二句逻辑上是sb.send anything for you.,说明所修饰名词的内容：We have made a plan to finish the work.被修饰名词是不定式逻辑主语：He is the first to get here.,5,（6）作状语：,5,注意不定式放句首时，逻辑主语与句子主语要一致：wrong：To save money,every means has been tried.right：To save money,he has tried every means.wrong：To learn English well,a dictionary is needed.right：To learn English well,he needs a dictionary.,表目的,既可以放在句首(相当于in order to do)，也可以放在句尾(相当于in order to/so as to do)：He worked day and night to get more money.She sold her hair to buy the watch chain.,表结果(往往是与预期愿望相反的结果;意料之外),常放在only/never后：He arrived late only to find the train had gone.I visited him only to find him out.After that day they were separated,never to see each other again.,5,表程度：Its too dark for us to see anything.The question is simple for him to answer.,表原因,常放在形容词后面：They were very sad to hear the news.,（7）作独立成分(插入语)：To tell you the truth,I dont like the way he talked.,5,（9）不定式的并列：第二个不定式可省略to。He wished to study medicine and become a doctor.,（8）不定式的省略：保留to省略do动词。If you dont want to do it,you dont need
