下面仅谈其作定语和表语的用法 一 过去分词作定语 过去分词作定语有前置和后置两种情况 1 前置定语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 a类 被动意义anhonoredguest一位受尊敬的客人theinjuredworkersarenowbeingtakengoodcareofinthehospital 受伤的工人正在医院受到良好的照料 b类 完成意义aretiredteacher一位退休的教师theyarecleaningthefallenleavesintheyard 他们正在打扫院子里的落叶 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 e g thiswillbethebestnovelofitskindeverwritten thathaseverbeenwritten 这将是这类小说中写得最好的 whoweretheguestsinvited whohadbeeninvited toyourpartylastnight 昨晚被邀请参加你的晚会的那些客人是谁呀 二 过去分词作表语 过去分词作表语无 完成 或 被动 之意 而是表示主语的状态或思想感情等 例如 helookedworriedafterreadingtheletter 看完信后 他显得很忧虑 whenweheardofthestory weweredeeplymoved 当我们听到这个故事时 被深深地感动了 heseemedquitedelightedattheidea 听到这个想法 他似乎很高兴 常见的作表语的过去分词有 amused 愉快的 connected 连接的 broken 破碎的 closed 关闭的 astonished 吃惊的 covered 覆盖的 crowded 拥挤的 delighted 高兴的 disappointed 失望的 dressed 穿着的 drunk 喝醉的 experienced 有经验的 gone 遗失的 lost 丢失的 worried 担忧的 interested 感兴趣的 tired 疲劳的 pleased 高兴的 satisfied 满意的 surprised 吃惊的 married 已婚的 known 著名的 等等 注 过去分词作表语不要与被动语态混为一谈 分词作表语表示主语的状态 而被动语态则表示被动的动作 例如 myglassesarebroken 我的眼镜碎了 状态 myglasseswerebrokenbymydaughter 我的眼镜被女儿摔碎了 动作 ontheearth 70 ofthesurfaceiscoveredwithwater 地球表面70 是被水覆盖的 状态 iwasgreatlysurprisedbytheknockatthedoor 敲门声使我大为吃惊 动作 随堂检测课本p52 completethetablewithphrasesthathavethesamemeaning seatswhicharereserved astonishedchildren awinnerwhoispleased aroomthatiscrowded
