translation onpage56 workbook usefulstructure 20ms theappositive words phrasesandclauses 同位语从句与that引导的定语从句的区别 1 同位语从句与名词之间在逻辑上是 主语 be 表语 的关系 该名词是需要做特殊说明的抽象名词 例如 a 听说他们的队赢了 他们很高兴 b 消息就是他们队赢了 theyweredelightedatthenewsthattheirteamhadwon thenewswasthattheirteamhadwon 2 从引导词来看 引导词that在同位语从句中是连词 只起连接作用 无具体词义 that不可省略 that在定语从句中是关系代词 它在从句中充当一定成分 主语或宾语 有具体词义 作宾语时还可以省略 例如 a thefactory wevisitedyesterdayisachemicalone b thenews hewillleaveforshanghaiistrue that that 定语从句 同位语从句 3 同位语从句的简易判断方法 同位语与其先行词之间在逻辑上是 主语 be 表语 的同位语关系 所以 可以在名词从句之间加系动词be 使之构成一个新句子 如果合乎逻辑 句子通顺 则原句为同位语从句 定语从句是不能够有系表结构把先行词与从句连接起来的 例如 thebeliefthattheearthisflatisstillheldinsomecountries thebeliefisthattheearthisflat 另外 能用于名词性从句的名词有 ability patience anxiety answer order report wish decision suggestion belief doubt fact hope message news promise question reply等等 1 alongwiththeletterwashispromise hewouldvisitmethiscomingchristmas 2004春季上海 a whichb thatc whatd whether 答案b 这是一个同位语从句 解释promise的具体内容 要用that引导 高考链接 2 thereisanewprobleminvolvedinthepopularityofprivatecars roadconditionneed 2003年上海 a that tobeimprovedb which tobeimprovedc where tobeimprovedd when improving 解析 答案为a that引导同位语从句说明 新问题 的内容 need后既可接动名词的主动式 也可接动词不定式的被动式作宾语 3 there safeelinginme we llneverknowwhataufois notever 2002年上海 a thatb whichc ofwhichd what 解析 答案a 同位语从句thatwe llneverknowwhataufois notever作afeeling的同位语 解释afeeling的具体内容 that连接同位语从句时 只起连接作用 不作从句的任何成分 4 informationhasbeenputforward moremiddleschoolgraduateswillbeadmittedintouniversities 2001年上海 a whileb thatc whend as 解析 答案b that引导从句作information的同位语 解释information的具体内容 5 thesewildflowersaresospecialiwoulddo icantosavethem nmet2000春季北京 a whateverb thatc whichd whichever 解析 答案a do后接宾语从句 宾语从句ican后省略了do 缺少宾语 whatever在宾语从句中作宾语
