过去分词作定语时,通常可替换某些定语从句.此时要注意两点:首先,在被替换的定语从句中,主语必须是作从句主语的关系代词;其次,定语从句中的谓语动词通常使用表示已经完成的时态或被动语态.\x0d例如:\x0d1.Prices of daily goods_through a computer can be lower than store prices.(2002北京春招)\x0dA.are bought B.bought C.been bought D.buying\x0d2.The managers discussed the plan that they would like to see_the next year.\x0dA.carry out B.carrying out C.carried out D.to carry out\x0d思路分析:此题考查see sb./sth. done句型.因the plan与carry out逻辑上是被动关系,故答案为C,其中that引导了一个定语从句.\x0d3.The Olympic Games,_in 776 B.C.,did not include women players until 1912.\x0dA.first playing B.to be first played C.first played D.to be first playing\x0d思路分析:the Olympic Games与play之间是被动关系,故排除A、D项.B项是不定式的被动式,表示"未来",也可排除,因此,C项是对的.它相当于一个非限制性定语从句which were first played.\x0d4.The first text books_for teaching English as a foreign language came out in the 16th century.\x0dA.having written B.to be written C.being written D.written\x0d思路分析:A项不能作后置定语,B项表示未来的动作,C项表示正在进行的动作.text books与write之间是被动关系,而且原题中的the first text books与came out in the 16th century也可暗示考生选written,表被动且完成的意思,故答案为D项.\x0d过去分词作定语有前置和后置两种情况.\x0d1、前置定语\x0d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.\x0dA类:被动意义:\x0dan honored guest 一位受尊敬的客人\x0dThe injured workers are now being taken good care of in the hospital.\x0d受伤的工人现正在医院受到良好的照料.\x0dB类:完成意义:\x0da retired teacher 一位退休的教师\x0dThey are cleaning the fallen leaves in the yard.\x0d他们正在打扫院子里的落叶.\x0d2、后置定语\x0d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.如:\x0d这将是这类小说中写得最好的.
