payingattentiontotheunderlinedparts 宾语从句 概念 在复合句中 由一个句子充当宾语 这个句子叫做宾语从句 宾语从句由 关联词 主语 谓语 构成 引导宾语从句的关联词有that if whether what who where why和how等 Grammar 总结一下吧 宾语从句的三要素 一 关联词 that if whether what who where why和how等 二 时态 当主句用一般过去时时态时 宾语从句要用过去的某种时态 三 语序 宾语从句用陈述句语序 即 主语 谓语 如 e g Heaskedmewheremyschoolwas Ididn tknowwhoshewas 连词that不能省略的几种情况在由that引导的宾语从句中 由于连词that只起引导功能 无具体意义 不担当任何成份 因此在口语或非正式的文体中常可省略 然而 大凡规则总有例外的情况 在下列that引导的宾语从句中 that则不能省略 1 从句的主语是that 如 Hesaysthatthatisarealking shat 他说那是一个真的王冠 2 that从句中含有主从复合句 如 I mafraidthatifyou velostit youmustpayforit 3 主 从句之间有插入语时 如 Itsayshere onthiscard thatitwasusedinplays 卡片上写着 它是古代演戏用的 4 若出现两个或两上以上的由that引导的宾语从句 且由并列连词连接时 只有第一个连词that可以省略 如 Shesaid that shewouldcomeandthatshewouldalsobringherson 她说她要来 还要带她的儿子来

was leaving if whether if和whether引导宾语从句时 作 是否 讲 一般情况下 二者没有区别 可以换用 但if常用于口语中 whether比较正式 如 Millieaskedif whetherhelikedthissweater 米莉问他是否喜欢这件羊毛衫 Thefishermanwantstoknowif whetheritwillrain 渔民想知道天是否会下雨 Objectclauseswithifandwhether 由if whether引导的宾语从句 if和whether引导宾语从句时 要注意宾语从句三要素 即连词 语序和时态 由于if和whether连接的是一般疑问句 因此要注意把从句语序改为陈述句语序 如 DoesMrZhaoliveinRoom208 Couldyoutellme Couldyoutellmeif whetherMrZhaolivesinRoom208 其次要注意时态变化 1 若主句是一般现在时 从句用任何所需时态 如 Hewantstoknowif whethertheyhadagoodjourneyhome 他想知道他们回家旅途是否愉快 2 若主句是一般过去时 从句则用跟过去相关的时态 即一般现在时变为一般过去时 现在进行时变为过去进行时 一般将来时为过去将来时 现在完成时态变为过去完成时 如 Didthetrainleave Shedidn tknow Shedidn tknowif whetherthetrainhadleft if和whether的区别二者在下列几种情况下不能换用 1 宾语从句置于句首表示强调时 应用whether 不用if 如 Whetherthisistrueornot Ican tsay 这是否对 我不能说 2 宾语从句与ornot直接连用时 应用whether 不能用if 如 Idon tknowwhetherornothewillcometomorrow 我不知道他明天是否来 3 与动词不定式连用时 只能用whether 如 Shecan tdecidewhethertogotoAmerica 她不能决定是否去美国 4 从句作介词宾语时 只能用whether 如 IworryaboutwhetherIhurtherfeeling 我担心是否伤了她的感情 5 宾语从句的谓语动词是否定形式时 只能用if 不能用whether 如 Tomwantstoknowifhewon tcomeheretomorrow 汤姆想知道他明天是否不来这儿 6 if意为 假如 如果 时 可以引导条件状语从句 而whether没有这个用法 如
