swhatweshoulddo That swhyIwanttoseeyou 表语从句的用法 4 ThereasonformyabsencewasthatIwasill be seem look等动词后均可跟表语从句 如 Mysuggestionisthatweshouldgoshopping Itseemsthatitisgoingtorain 5 2 asif because也可引导表语从句 如 Itlooksasifit sgoingtorain ItwasbecauseIgotuplate 3 在非正式文体中 引导表语从句的that可以省略 如 Thetroubleis that heisill 6 在表语从句中 当reason做主语时 引导词只能用that 不能用because 如 他迟到的原因是因为他没有赶上早班车 Thereasonwhyhewaslatewasthathedidn tcatchtheearlybus Attention 7 Thattheearthisroundistrue Itistruethattheearthisround 主语从句的用法 一 主语从句在句中作主语 主语从句可以位于句首 但常见的主语从句多放在句末 句首则用形式主语it 8 2 Whetherhewillcomehasn tbeendecided Ithasn tbeendecidedwhetherhewillcome Attention 连词that whether在从句中不担任句子成分 只起连接作用 不能省略 注 if不可用来引导主语从句 9 二 用it作形式主语的结构 1 Itis 名词 从句事实是 Itisafactthat 非常荣幸Itisanhonorthat 是常识Itiscommonknowledgethat 10 2 Itis 形容词 从句 多用should Itisnaturalthat 很自然 Itisstrangethat 奇怪的是 3 Itis 不及物动词 从句Itseemsthat 似乎 Ithappenedthat 碰巧 Itappearsthat 似乎 11 4 Itis 过去分词 从句Itisreportedthat 据报道 Ithasbeenprovedthat 已证实 Itissaidthat 据说 12 三 It作形式主语和it引导强调句的比较It作形式主语代替主语从句 主要是为了平衡句子结构 主语从句的连接词有变化 而it引导的强调句则是对句子某一部分进行强调 无论强调的是什么成分 都可用连词that 被强调部分指人时也可用who whom 例如 13 Itisapitythatyoudidn tgotoseethefilm Itdoesn tinterestmewhetheryousucceedornot Itisinthemorningthatthemurdertookplace ItisJohnthatbrokethewindow 14 学习主语从句应该注意的几个问题1 引导词that与whatwhat既有引导主语从句的作用 同时又在从句中作句子成分 主语 宾语 表语等 这时what相当于allthat everythingthat 常译成 所 的 东西 事情 话等 而that只起连接作用 本身无实际意义 在从句中也不担当任何句子成分 但that引导的主语从句放在句首时 不能省略that 15 例如 1 Whatwecan tgetseemsbetterthanwhatwehave 2 Thatweshouldworkoutaplantodealwiththeserioussituationisimportant 16 2 引导词if和whetherif和whether引导动词后的宾语从句时一般可通用 但介词后的宾语从句 主语从句 放在句首时 表语从句常由whether引导 例如 17 Whethershewillgohomeornotisunknown Itremainstobedecidedwhether ifweshallraiseducksorgeese 18 2012陕西卷 Asmanyfivecoursesareprovided andyouarefreetochoose suitsyoubest A whateverB whicheverC wheneverD wherever 解析 考查名词性从句

且that在句中无意义 并不充当任何成分 D 20 2012湖南卷 Everyoneinthevillageisveryfriendly Itdoesn tmatter youhavelivedthereforashortoralongtime whyB howC whetherD when 考查名词性从句引导的用法 根据空后的or可知为whether or短语 复合句名词性从句主语从句形式主语引导词whether C 21 2012全国新课程 24 Itisbynomeansclear thepresidentcandotoendthestrike howB whichC thatD what 解析 此处it是形式主语 what引导的是主语从句 作真正的主语 What作do的宾语 句意 总统采取什么行动结束这次罢工一点也不清楚 D 22 2012山东卷
