1、,Grammar,The Past Participle,过去分词,过去分词是非谓语动词的一种形式,表示完成和被动的动作。它在句子中可以充当状语、定语、表语和宾语补足语等成分。,Past participle,若是及物动词（vt）则表示被动；动作已经完成（即先于谓语动词）若是不及物动词（vi）则只表示完成。如：a broken glass=a glass which has been broken a fallen leaf=a leaf which has fallen(down),一.形式与含义,二.过去分词的作用：Past participle can be used as adverb

2、ial,attribute,predicative&object complement.,1.过去分词做定语：,表示分词动作与所修饰的名词之间存在被动关系。单一的过去分词做定语一般放在被修饰的名词之前；过去分词短语做定语放在被修饰的名词之后，过去分词及过去分词短语做定语均可以转换为一个定语从句。,a broken heart,一颗破碎的心,the risen sun,已经升起的太阳,a lost dog,丧家之犬,people addicted to drugs,a school built for orphans,过去分词作定语有前置和后置两种情况:,单个的过去分词作定语,通常放在被修饰的名

3、词之前,表示被动和完成意义。,1）.前置定语,被动意义：,an honored guest,一位受尊敬的客人,(受伤的工人)are now being taken good care of in the hospital.,B.完成意义,a retired teacher,一位退休的教师,They are cleaning(落叶)in the yard.,The injured workers,the fallen leaves,2）.后置定语,过去分词短语作定语时,通常放在被修饰的名词之后,它的作用相当于一个定语从句。,This will be the best novel of its k

5、town.Nothing reported(in the newspaper)interested him.,注意:,破损的窗户很快就会被换掉。_will be replaced soon.=The window which was broken will be replaced soon.,昨天买的书确实不错。The books _are of high quality.=the books which were bought yesterday are of high quality.,The broken window,bought yesterday,过去分词及过去分词短语做定语均可以

7、ung man sleeping on the bench.(在进行)=I know the young man who is sleeping on the bench.6.The letter mailed last night will reach him tomorrow.(已完成)=The letter which was mailed last night will reach him tomorrow.,Summary:不定时表示未发生或强调具体的动作。V-ing表示正在发生的动作。过去分词表示完成、被动的动作。,过去分词作定语时，所表示的动作在谓语所表示的动作之前发生.The

9、played B.to be first played C.first playing D.to be first playing,过去分词做定语与其修饰词之间是动宾关系且过去分词表示的动作已完成。现在分词作定语表示动作正在发生，与修饰词是主谓关系。不定式作定语表示将要发生的动作。first played in 776B.C.=which was first played in 776 B.C.,1.The Olympic Games,_ in 776 B.C.did not include women players until 1912.,考点点拨,2.Whats the language

10、 _ in Germany?A.speaking B.spoken C.be spoken D.to speak 简析:该题应选B。测试过去分词作后置定语表达被动,等于定语从句 which is spoken。,3.Most of the artists _ to the party were from South Africa.A.invited B.to invite C.being invited D.had been invited 简析:该题应选A。测试过去分词作后置定语表达被动,等于定语从句who were invited。,4.The computer centre,_ last

14、动的动作发生在谓语动词之前,则可使用现在分词的完成被动式或过去分词。,2).过去分词作时间状语,1.When it is heated,ice will be changed into water.When heated,ice will be changed into water.,2.When it is seen under a microscope,a fresh snowflake has a delicate six-pointed.,a fresh snowflake has a delicate six-pointed shape.,Seen under a microscop

26、,Used,Using,Looking,Looked,注意：分词在句子中作状语时，选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，就选用现在分词，如果是被动关系就用过去分词。,另外,当分词作状语时,如果其逻辑主语与整个句子的主语不一致时,需要用独立主格结构或 with 复合结构来替代。(此时,也可把该分词看成介词的宾语补足语。),例:The murderer was brought in,with his hands _ behind his back.A.being tied B.having tied C.to be tied D.tied 简析:很显然,待选部分

27、的逻辑主语是 his hands,而不是句子的主语 The murderer,而 his hands 对于动词 tie来说,只能是被动承受。因此,该题应选D。,表示时间The meeting being over,all of us went home.开完会后我们都回家了。Her work done,she sat down for a cup of tea.她干完了活，坐下来喝茶。表示条件The condition being favourable,he may succeed.若条件有利，他或许能成功。Weather permitting(=If weather permits),the

32、)He is retired.他已退休。3.有些过去分词作表语时，构成的谓语很接近被动结构。(3)The city is surrounded on three sides by mountains.这座城市三面环山。,【注意】过去分词作表语与被动语态的区别：过去分词作表语，主要是表示主语的状态，而被动语态则表示动作。The cup was broken by my little sister yesterday.茶杯是昨天我小妹打碎的。（是被动语态，表示动作）The cup is broken.(表示杯子破了的状态。)(3)The library is now closed.图书馆关门了。（

33、过去分词作表语）,The window is broken.窗户碎了。Dont get so excited.别这么激动。,常见作表语的过去分词有：disappointed,drunk,amused,frightened,married,excited,experienced,interested,confused,pleased,puzzled,satisfied,tired,worried等。,Cleaning women in big cities usually get _ by the hour.A.pay B.paying C.paid D.to pay,C,该题考查分词作表语的用

38、些事情做完。【注意】过去分词所表示的动作一定和宾语有逻辑上的动宾关系。,（二）使役动词have接过去分词作宾补有两种情况。1.过去分词所表示的动作由他人完成。(1)He had his money stolen.他的钱给偷了。（被别人偷去了）2.过去分词所表示的动作由句中的主语所经历。如：(2)He had his leg broken.他的腿断了。（自己的经历）,5.“with 宾语过去分词”结构“with 宾语过去分词”结构中，过去分词用作介词 with的宾语补足语。这一结构通常在句中作时间、方式、条件、原因等状语。例如：(1)The murderer was brought in,wit
