herjobwastotakecareofthewoundedsoldier wearedoingourwrittenexercises themachinerunbytheoldworkerismadeinshanghai 过去分词作定语 过去分词作定语时 它的作用相当于一个定语从句 thiswillbethebestnovelofitskindeverwritten whoweretheso calledguestsinvited toyourpartlastnight thathaseverbeenwritten whohadbeeninvited 如果被修饰的词是由every some 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 isthereanythingunsolved thereisnotingchangedheresinceileftthistown 注意 2 表示情感的动词的过去分词由表示情感或心理状态的动词的过去分词作定语时 通常不可以修饰无生命物 有些过去分词已经完全形容词化 常见的这类过去分词有 disappointed moved interested touched surprised shocked puzzled frightened等 afrighteneddriver吓坏了的司机adisappointedgirl感到失望的女孩 3 不及物动词的过去分词作定语时只表示动作的完成 而没有被动语态的意义 如 newly arrivedgoods新到的fallenleaves落叶fadedflowers凋谢的花 1 what sthelanguage speak ingermany spoken 简析 测试过去分词作后置定语表达被动

opened 简析 测试过去分词短语作定语放在所修饰的名词后 可以用非限制性定语从句 whichwasopenedlastyear 代替 4 thefirsttextbooks write forteachingenglishasaforeignlanguagecameoutinthe16thcentury written 简析 测试过去分词作后置定语表达被动 等于定语从句whichwerewritten 1 过去分词作状语时其逻辑主语应该和句子的主语保持一致 通常过去分词在句中可以作时间状语 原因状语 方式状语 伴随状语和让步状语等 而且可以与对应的状语从句进行句型转换 过去分词作状语 过去分词作时间状语 1 whenitisheated icewillbechangedintowater whenheated
