四级语法讲座2：非谓语动词.ppt

,四级英语语法讲座重点二 非谓语动词,重点二 非谓语动词,非谓语动词既是四级考试的重点也是难点，在每年的考试中都占有相当大的比例。其中最为重要的是分词作状语和独立主格结构。,一、知识点,非谓语动词包括现在分词、过去分词、不定式和动名词。非谓语动词既是四级考试的重点也是难点。因为非谓语动词的用法很复杂，它既含有时态语态的变化、又有否定形式。例如：He seemed to have waited there for a long time.(不定式的完成时态)He seemed to be waiting for someone.(不定式的正在进行时)He seemed to have not known the place very well.(不定式的完成时态的否定形式)He seemed to have been told about it.(不定式的被动语态),现在分词,现在分词可以用作状语、定语和表语，表主动的含义。例如：The film is exciting.(表语)The exciting film attracted the children very much.(定语)Having finishing the homework,children went to the playground to play basketball.(状语)The problem being discussed is what they are concerned with.(定语),过去分词,过去分词的用法与现在分词大体相当，可以用作状语、定语和表语，只是表示被动的意义。例如：Children are excited at the film.(表语)The excited children sang and danced to the midnight.(定语)Excited at the news,children went to the playground to play basketball.(状语)This was the problem discussed at the meeting yesterday.(定语),不定式,不定式有两种形式：带to的不定式和不带to的不定式,不定式有进行体、完成体和被动语态。不定式在句中可以作主语、宾语、补语、定语和状语等。It is of Importance to have good friends.(逻辑主语)To see is to believe.(主语)I expect him to come back soon.(宾语补语)I dont know how to get there.(宾语)We need someone to help us.(定语)To get there earlier,we started at 6 oclock.(状语)The room seemed to have been cleaned.(表语),动名词,动名词具有动词的特征（可有自己的状语、宾语等）和名词的功能（在句中可以作主语、宾语、补语）。I dont liking talking with her.(宾语)Smoking is dangerous for health.(主语)Her hobby is collecting coins.(表语),二、四级考试中的非谓语动词考点,非谓语动词的时态和语态The two buildings being repaired now are the students dormitories.(正在进行时表示动作正在发生，被动语态表示被动)The two buildings repaired during the summer vacations are the students dormitories.(过去分词作定语，表示动作完成)The two buildings to be repaired are the students dormitories.(不定式表示动做未发生，将要发生,非谓语动词的否定形式和物主代词的用法,Not knowing what to do next,he asked me for help.(分词作状语的否定形式)I regret not telling her the news earlier.(动名词作宾语的否定形式)I dont mind your being late.(动名词作宾语的物主形式)I persuade him not to stay there too long.(不定式作补语的否定形式),现在分词和过去分词区别,现在分词表示现在和主动的意思；过去分词含有被动和完成的意思。例如；Originally cultivated In India,the banana brought to the Americas by the Portuguese who found it In Africa.句中主语the banana和cultivate的关系应属被动关系，用过去分词Originally cultivated。The lost child was found hiding in the cave.句中hiding in the cave与其主语the child是主动关系，用现在分词。,不定式和动名词的区别,不定式和动名词都可以作宾语，但在英语中不同的动词要求后边的宾语形式不同。有些动词要求动名词所宾语，有些动词要求不定式所宾语，还有些动词既可以用动名词又可以用不定式作宾语，但所表达的意思却不同。所以大家要记住这些特殊的动词。,不定式和动名词的区别,要求不定式作宾语的动词有：expect,urge,intend,persuade,prefer,cause,encourage,tell,ask,make,let,要求动名词作宾语的动词有：mind,quit,resent,mention,appreciate,postpone,consider,enjoy,deserve,delay,avoid,escape,deny,resist,admit,fancy,give up,cannot but,need,want，feel like下列动词既可以用动名词又可以用不定式作宾语：remember,forget,regret,mean,like,hate,love,stop,不定式和动名词的区别,remember,forget,regret后接不定式表示动作尚未发生；接动名词表示动作已经发生。like,hate,love 后接不定式表示具体的或一次性的动作；接动名词表示习惯性或抽象性的动作。stop 后接不定式表示停下现在动作去做另一件事；接动名词表示停下现在所进行的动作。mean 后接不定式表示打算去做一件事；接动名词表示意思是什么。,几种特殊的句型,It is no good(use)+doing sth.It is no use arguing with her about the matter.There is no _ doing sth.There is no telling when to start.But+(to)do:介词前动词若是实义动词do，省略to;介词前动词若不是实义动词do，则不能省略to。Our parents required us of nothing but to study hard.He said nothing but to cry.He did nothing but cry.,分词的固定搭配,分词的固定搭配词组：judging from,generally speaking,considering,takinginto consideration,compared to(with),分词作状语,过去分词和现在分词（包括一些形容词）短语皆能作状语，其作用相当于状语从句，只不过是何种状语从句要根据句子的内容而确定。如：Having(=As/Because I had)no money,I borrowed some from John.（表原因）Walking(=When I was walking)along the bank,I met a friend.(表时间)Turning(=If you turn)to the right,you will see the shop.(表条件)注意有时分词状语的前面可以加连词。如：Although defeated(=although he has been defeated)many times,he still challenges me.When cursed(=when she was cursed)by the witch,the princess felt very weak.,独立主格结构,独立主格结构是带有逻辑主语的分词短语，有以下形式：主语分词The problem being solved,he went back home.Time permitting,we will go outing this weekend.The report having been read a lively discussion began.With+逻辑主语+分词（形容词、副词或介词短语等）The old man came in with a book under his arm.They went home with the lights on.,分词作状语与独立主格结构,要注意区分分词作状语与独立主格结构，前者的逻辑主语是与句子的主语是一致的，而后者有自己的主语，即分词的前面有名词/代词，否则句子的意义就不通。如：Getting dark,I left in a hurry.这是个错句。正确的形式是在分词前加上它的主语it.再如：Stepping on the platform,the audience gave John a thunderous applause.这个句子的真正意思是想说：当John登上舞台的时候，观众爆发出雷鸣般的掌声。正确的说法应是：Stepping on the platform,John received/was given a thunderous applause.,三、非谓语动词考点例题,时态1.As a public

life.(02/6/54)A)remembering B)to remember C)to be rememberedD)being rememberedA)本题的考点与上题相似，既要考虑选动词不定式还是动名词，又要考虑主动还是被动。空格前面的worth是本题的关键，它的后面要求接名词形式，但当后面是动名词时，常用主动形式表达被动的概念。再如：The book is well worth
