重点句式教材原句p.56 UNESCO awarded Shennngjia this status because it meets tw criteria required by the list. 联合国教科文组织令神农架入选是因为它符合入选名录的两项标准。【句式分析】过去分词短语 required by the list 作后置定语。tw criteria 与 require 是被动关系,故 require 用过去分词形式。过去分词(短语)作定语(1)位置:单个的过去分词作定语时,常放在被修饰词之前;过去分词短语作定语时,常放在被修饰词之后,其作用相当于一个定语从句。the fallen leaves 落叶paintings painted by a girl =paintings that are painted by a girl 一个女孩的画作
(2)意义:及物动词的过去分词作定语,表示被动和完成;不及物动词的过去分词作定语,只表示动作已完成,不表示被动。a furnished rm 有家具的房间(表示被动和完成)the questin discussed yesterday 昨天讨论的问题(表示被动和完成)a retired teacher 一名退休教师(只表示完成)an escaped prisner 一名逃犯(只表示完成)
