forEmphasis强调句的基本结构ThequestionformsofEmphasis强调句的疑问结构HowtotellEmphasissentencesfromsomeotherrelatedsentences强调句型与其它相关的句型 目录 强调句型的结构为Itis was that who 主要用来强调主语 宾语和状语成份 也可以强调表语和宾语补足语 被强调的部分放在is was的后面 如果被强调的是人 则后面用that或who 如果被强调的是物或其他情况 则一律用that 如 强调句的基本结构 目录 ItwasJimwho thatshotabearyesterday 强调主语JimItwasabearthatJimshotyesterday 强调宾语abearItwasyesterdaythatJimshotabear 强调时间状语yesterdayItisadoctorthathewantstobe 强调表语adoctorItisgreenthattheyhavepaintedthewall 强调宾语补足语green 目录 用强调句型分别强调下面句中划线部分 Themotherdressesherbabyeverymorning Itisthemotherthat whodressesherbabyeverymorning Itisherbabythat who themotherdresseseverymorning Itiseverymorningthatthemotherdressesherbaby 目录 强调句的疑问句式 强调句也有疑问句式 它的一般疑问句式为 Is wasIt that who 特殊疑问句式为 特殊疑问词 Is wasitthat who 特殊疑问词为被强调部分 目录 按要求改写下列句子 ItwasTomwhohelpedmelastnight 改为一般疑问句 WasitTomwhohelpedyoulastnight ItwasTomwhohelpedmelastnight 就划线部分提问 Whowasitthathelpedyoulastnight 注 以who开头的疑问句 强调人时 只能用that导出句子其余成份 而不能用who 目录 ItwasTomwhohelpedmelastnight 就划线部分提问 WhomwasitthatTomhelpedlastnight ItwasTomwhohelpedmelastnight 就划线部分提问 WhenwasitthatTomhelpedyou 注 以whom开头的疑问句 强调人 也只能用that导出句子其余成份 而不能用who whom 目录 学习强调句型应该注意的几个问题 1 如果被强调的是句子的状语 则不可用when where或because等相应的词 而必须用that 如 ItwasonthebusthatImetheryesterday 强调地点状语onthebus 注意不能用where 目录 ItwaswhenIwasinthekitchenthatIheardanexplosion 目录 ItwasthosechildrenthatIsawplayingbythepond 尽管强调的是thosechildren 是复数 仍然用was Itwasstupidstudentswho thatdon taskquestions 尽管强调的是stupidstudents 是复数 仍然用is 目录 如果被强调部分是名词或代词的复数形式 系动词仍然用is或was 如 3 在强调主语时 that who后的谓语应与前面被强调的主语保持一致 如 Itisyouwhoarewrong are与you保持一致ItisIwhoamwrong am与I保持一致ItisMr Wilsonwho thatisthechairman is与Mr Wilson保持一致 目录 4 在强调until引出的时间状语时 其句型为 Itisnotuntil that 一般多译成汉语的肯定句 如 Itwasnotuntil1972thatwebeganstudyingEnglish 直到1972年我们才开始学习英语 ItwasnotuntilyesterdaythatInoticedit 我一直到昨天才注意到它 目录 Whenwasitthatthestorytookplace Wasitwhenthatthestorytookplace Whatisitthatyouhavetosell Isitwhatthatyouhavetosell 5 由since as引导的原因状语不可以作为被强调的部分 如不能说 目录 如果将句中的itis was和that who去掉 看剩余的部分结构是否完整 句意是否明了 如果是 则为强调句型 否则就不是 如 判断是否为强调句的方法 ItwasMarythathaswonthefirstplace 将句中的itwas和that去掉 原句变为 Maryhaswonthefirstplace 句子结构完整 表意明确 故原句为强调句 再如 目录 ItissurprisingthatMaryshouldhavewonthefirstplace 如果将itis和that去掉 那么原句变为 Maryshouldhavewonthefirstplacesurprising 这个句子不完整 所以原句不是强调句型 此句中it为形式主语 真正的主语是that引导的从句 目录 强调句型与相关句型的辨析 强调句型与定语从句的区别 Itishightimethatwewenttowork 该是我们上班的时候了 Itisthewaythathebehaves 这就是他的处事之道 Itisthefactorythatproducescellphones 这家工厂是生产手机的 ItisthemanthatImetyesterday 我昨天碰到的就是这个人 辩析 句1和句2只能看作定语从句 that在从句中作关系副词 句2中that可用inwhich替换 且可省 句3和句4多看作强调句 that在从句中不作成份 且无意义 只构成强调句 也可看作定语从句 句3中that which充当从句主语 译为 这就是生厂手机的那家工厂 句4中that who whom充当从句宾语 译为 这就是我昨天碰到的那个人 目录 2 强调句型与主语从句的区别 ItistheGreatWallthatwearegoingtovisit 我们要去参观的地方是长城 ItistruethatwearegoingtovisittheGreatWall 我们真的要去参观长城 辩析 句1为强调句 强调宾语theGreatWall 如果去掉itis that 结构 该句仍然正确 意义完整 句2为主语从句 that引导的从句是句子真正主语 it是形式主语 如果去掉itis that 结构 则该句不成立 目录 2 强调句型与状语从句的区别 Itwasthreeo clockwhenhefinishedthetask 他完成任务的时候已经3点钟了 Itwasatthreeo clockthathefinishedthedifficulttask 他是3点钟完成任务的 辩析 句1为状语从句 when不能构成强调句 when引导的时间状语从句用来说明主句谓语动作发生的时间 句2为强调句 强调的是时间状语atthreeo clock 目录 Exercises I Rewritethesentences emphasizingtheunderlinedpart 1 Inearlytimespeopletraveledonfootoronhorseback
