语法点击实战演练Unit2单元语法聚焦语法点击感叹句感叹句是表示惊讶、赞美、喜悦、愤怒等情感的句子，通常由what或how引导。常见结构：Whata/an＋形容词＋可数名词的单数(＋主语＋谓语)!What＋形容词＋可数名词的复数(＋主语＋谓语)!What＋形容词＋不可数名词(＋主语＋谓语)!How＋形容词或副词(＋主语＋谓语)!How＋主语＋谓语！Whatabraveboyheis!他是多么勇敢的一个男孩啊！Whatgoodweatheritis!今天的天气真好！Howinterestingthestoryis!这个故事多么有趣啊！Howfasttheathleteruns!那名运动员跑得真快啊！宾语从句的引导词和语序宾语从句是名词性从句的一种，在复合句中作主句的宾语。在本单元，我们将重点讲解宾语从句的引导词和语序。1．宾语从句的引导词选择宾语从句的引导词是有规律可循的，一般来讲，可分为三个类型：(1)当宾语从句是由陈述句变化而来时，该从句通常由that引导。that无具体意义，在句中不作任何成分，在口语或非正式文体中常常被省略。如：Weallsay.LiMingisagoodboy.→Weallsay(that)LiMingisagoodboy.(2)当宾语从句由一般疑问句变化而来时，需用连词if或whether引导，译为“是否”，不可省略。如：Couldyoutellus?Willhecomehere?→Couldyoutellusif/whetherhewillcomehere?注意：if和whether在引导宾语从句时一般可以换用，但以下三种情况只可以用whether，不可以用if。①当从句中含有or连接的选择成分时。如：Wedidn'tknowwhetherornotshewasready.我们不知道她是否已做好准备。②当从句作介词的宾语时。如：I'minterestedinwhetherhehasjoinedthearmy.我对他是否已经入伍感兴趣。③当宾语从句移至句首表示强调时。如：Whetherthisistrueornot,I'mnotsure.这是否真实，我不确定。(3)当宾语从句由特殊疑问句变化而来时，则用连接代词who,whose,whom,what,which或连接副词when,where,why,how等引导。它们在句中均充当一定成分，一般不可省略。如：Couldyoutellme?Whereisthenearestbank?→Couldyoutellmewherethenearestbankis?2．宾语从句的语序宾语从句要用陈述语序。如：Iwonderif/whetherhewilllistentome.我想知道他是否会听我的话。实战演练Ⅰ.单项选择()1.[2013·广东]MoYanwontheNobelPrizeforLiteraturelastyear.________excellentheis!A．HowB．WhatC．WhataD．WhatanA[解析]感叹形容词excellent要用how。()2.[2013·长沙]________clevertheboyis!A．HowB．WhatC．WhataA()3.[2013·济南]—HaveyouheardofZhangLili?Shewasseriouslyhurtinanaccidentinordertosaveoneofherstudents.—________goodteacher!A．HowB．WhatC．WhataD．WhatanC[解析]感叹名词teacher要用what，而且teacher是可数名词的单数形式，故whata符合题意。()4.________wonderfulconcerttheyareputtingoninthecitysquare!A．HowB．WhatC．WhataD．WhatanC()5.—________hardTonyisworking!—Yes.Weshouldlearnfromhim.A．WhatB．HowC．WhataD．HowaB[解析]本题考查感叹句的结构。感叹副词hard可知要用how。()6.Theywonder________robotswillmakehumanslosetheirjobsornot.A．thatB．ifC．whetherD．soC[解析]句意为“他们想知道机器人是否会使人类失去工作”。表示“是否”可以用if或whether，但结合题干中的ornot可知，whether符合题意。()7.[2013·梅州]Couldyoutellme________ameetinginGuangzhounextweek?A．iftherewasgoingtobeB．ifthereisgoingtobeC．whetheristheregoingtobeD．wherethereisgoingtohaveB[解析]句意为“你能告诉我下周是否会举行会议吗？”if,whether引导的宾语从句要用陈述语序，先排除C；再结合nextweek可知时态是将来时，排除A；D项中宾语从句的引导词是where，也可以排除。故答案为B。()8.[2013·鄂州]—Couldyoutellme________inyourhometowninwinter？—Sure.A．whetherdoesitoftensnowB．whetheritoftensnowsC．ifitoftensnowD．ifdoesitsnowB[解析]根据宾语从句要用陈述语序的规则可知答案为B。Ⅱ.把下面两个句子合并为宾语从句，括号中所给的词是引导词1．Iknow.Heisabraveman.(that)_______________________________________________________2．Lisawantstoknow.Willhecometoherbirthdayparty?(if)_______________________________________________________3．Myfatherwonders.Willtherebeaparents'meetingnextweek？(whether)_______________________________________________________4．Ithink.You'vegotagreatidea.(that)_______________________________________________________Iknowthatheisabraveman.Lisawantstoknowifhewillcometoherbirthdayparty.Myfatherwonderswhethertherewillbeaparents‘meetingnextweek.Ithinkthatyou'vegotagreatidea.5．Sheaskedme.DidIpasstheexamsuccessfully？(if)______________________________________________________6．Theywonder.HowdowecelebratetheNewYear'sDay？(how)______________________________________________________SheaskedmeifIpassedtheexamsuccessfully.TheywonderhowwecelebratetheNewYear'sDay.
