则可使用现在分词的完成被动式或过去分词 attention 过去分词表完成 被动 作状语时 其逻辑主语是主句的主语 且与主语之间存在着被动关系 过去分词作状语可表时间 原因 让步 结果 方式 条件等 观察下列的句子 Oncepublished hisworks Oncehisworkswaspublished

Aletterpostedtodaywillreachhimthedayaftertomorrow 今天发出的信后天就能收到 分词作定语可以转换成定语从句 Heworkedasaworkerbuildingroads 主动 Heworkedasaworkerwho thatbuiltroads Thisisapicturepaintedbymyfather 被动 Thisisapicturewhichwaspaintedbymyfather Iknowtheyoungmansleepingonthebench 在进行 Iknowtheyoungmanwhoissleepingonthebench Thelettermailedlastnightwillreachhimtomorrow 已完成 Theletterwhichwasmailedlastnightwillreachhimtomorrow 过去分词短语有时亦可用作非限制性定语 前后常有逗号 Someofthem bornandbroughtupincountryvillages hadneverseenatrain 他们当中有一些人 生长在农村 从未见过火车 过去分词作定语有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 被动意义 anhonoredguest 一位受尊敬的客人 受伤的工人 arenowbeingtakengoodcareofinthehospital B 完成意义 aretiredteacher 一位退休的教师 Theyarecleaning 落叶 intheyard Theinjuredworkers thefallenleaves 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 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 1 TheOlympicGames in776B C didn tincludewomenuntil1912 A firstplayingB tobefirstplayedC firstplayedD tobeplaying 考点点拨 简析 首先 根据语法分析可知 待选部分是一个作定语 修饰TheOlympicGames的后置分词短语 再根据TheOlympicGames对于动词play来说只能是被动承受 且已完成 in776B C 因此 该题应选C 2 What sthelanguage inGermany A speakingB spokenC bespokenD tospeak简析 该题应选B 测试过去分词作后置定语表达被动 等于定语从句whichisspoken 3 Mostoftheartists tothepartywerefromSouthAfrica A invitedB toinviteC beinginvitedD hadbeeninvited简析 该题应选A 测试过去分词作后置定语表达被动 等于定语从句whowereinvited 4 Thecomputercentre lastyear isverypopularamongthestudentsinthisschool A openB openingC havingopenedD opened简析 该题应选D 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 5 Thefirsttextbooks forteachingEnglishasaforeignlanguagecameoutinthe16thcentury A havingwrittenB tobewrittenC beingwrittenD written简析 该题应选D 测试过去分词作后置定语表达被动 等于定语从句whichwerewritten 另外 分词作状语时 如果其逻辑主语与整个句子的主语不一致时 需要独立主格结构或with复合结构来替代 此时 也可把该分词看成介词的宾语补足语 例 Themurdererwasbroughtin withhishands behindhisback A beingtiedB havingtiedC tobetiedD tied简析 很显然 待选部分的逻辑主语是hishands 而不是句子的主语Themurderer 而hishands对于动词tie来说 只能是被动承受 因此 该题应选D 6 When ifshewouldrequestarise theactresssaidthatmoneywasnotimportant A askedB askingC havingaskedD beingasked 7
