18、就是句子的主语，且主语是过去分词动作的承受者，即过去分词表示的动作不是句子的主语发出的；过去分词与主语之间是动宾关系，即被动关系。这一点是与现在分词作状语的情况是不同的，后者与主语之间是主谓关系。Complete each sentence using the Past Participle of the right verb.1)_ by noises in the night,the girl no longer dared to sleep in her room.2)The lady returned home,_ by two policemen.frighten trap foll

19、ow shootFrightenedfollowed3)If _ in a burning building,you should send for help.4)Although _in the leg,he continued firing at the thief.trappedshotPast participle(3)Used as the attribute过去分词作定语过去分词作定语与其所修饰的词之间存在着逻辑上的被动关系,且表示该动作已经完成。单个的过去分词作定语,通常置于被修饰的词的前面；分词短语作定语时,须置于被修饰词的后面。1.Last Sunday we went on

20、 an organized trip to the forest.上周日我们进行了一次有组织的去森林的旅行。2.A letter posted today will reach him the day after tomorrow.今天寄出的信后天他就能收到。A.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 一位退休教师They are cleaning (落叶)in the yard.The injured worker

21、sthe fallen leaves过去分词作定语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词之前,表示被动和完成意义。1.前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 kindever written.=Who were the so-called guests invited(=)to your party last night?that has ever been writtenwho had been invited2.后置定语如果被修饰的词是由every/som

22、e/any/no+thing/body/one所构成的复合代词或指示代词those等时，即使一个单一的分词作形容词用，也要放在被修饰词的后面。例如：Is there anything unsolved?There is noting changed here since I left this town.注意:现在分词作定语，它与被修饰的名词存在着逻辑上的主谓关系，而且该动词的动作正在进行。过去分词做定语时，它与被修饰的名词存在着逻辑上有动宾关系，而且该动词的动作已经发生了。现在分词与过去分词作定语的区别He worked as a worker building roads.(主动)=He

23、worked as a worker who/that built roads.This is a picture painted by my father.(被动)=This is a picture which was painted by my father.I know the young man sleeping on the bench.(在进行)=I know the young man who is sleeping on the bench.The letter mailed last night will reach him tomorrow.(已完成)=The lette
