第一学期人教版新课标九年级英语第二单元语法宾语从句和感叹句的用法及练习

宾语从句（TheObjectClause）学习宾语从句要抓住三要素：连接词、语序和时态。一．宾语从句的定义宾语从句在复合句中起宾语的作用，可以作动词的宾语，也可以做介词的宾语作动词的宾语:Iheardthathewouldcomeherelateron.主语谓语动词一个句子作宾语作介词的宾语:Hesaidnothingaboutwhobrokethewindowlastnight.主语谓语动词代词作动词的宾语介词一个句子作介词的宾语二.宾语从句中引导词（连接词）的用法在复合句中作主句的宾语，引导词有连词：that(that常可省略),whether,if代词：who,whose,what,which副词：when,where,how,why等。连词：Hetoldme(thathewould)gotothecollegethenextyear他告诉我他明年上大学.Idon’tknowiftherewillbeabusanymore.我不知道是否还会有公交车.Nobodyknewwhetherhecouldpasstheexam.没有人知道他是否会通过考试.that引导的宾语从句（在非正式场合that可以省略）可跟that从句做宾语的动词有：say,think,insist,wish,hope,demand,imagine,wonder,know,suppose,see,believe,agree,admit,deny,expect,explain,order,command,feel,dream,suggest,hear,mean,notice,prefer,request,require,propose,declare,report等。Theboybelievesthathewilltravelthroughspacetootherplanets.Attention：宾语从句的否定转移当主句谓语动词是think,believe,suppose,expect等词，而宾语从句的意思是否定时，常把否定转移至主句表示。Idon’tthinkitisrightforhimtotreatyoulikethat.主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.Idon’tbelievethatmaniskilledbyJim,ishe?我认为那个人不是Jim所杀的,是不是?IexpectourEnglishteacherwillbebackthisweekend,won'tshe/he?Wesupposeyouhavefinishedtheproject,haven'tyou?如果宾语从句中有某个含有否定意义的形容词或副词(不包含带有否定前缀的词，如：unhappy，unfair，dislike等),其反义疑问句要用肯定形式.Wefindthatheneverlistenstotheteachercarefully,doeshe?我们发现他从不仔细听老师讲课，是不是？当主句的主语是第二、三人称时，其反义疑问句一般与主句保持一致。Yoursistersupposessheneedsnohelp,doesn'tshe?Youthoughttheycouldhavecompletedtheproject,didn'tyou?Theydon'tbelieveshe'sanengineer,dothey?Shedoesn'texpectthatwearecomingsosoon,doesshe?在以下情况中that不能省略1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。Ibelieve（that）youhavedoneyourbestandthatthingswillgetbetter．2．当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。

JustthenInoticed,forthefirsttime,thatourmasterwaswearinghisfinegreencoatandhisblacksilkcap.3．当that从句是双宾语中的直接宾语时，that不可省。

Ican’ttellhimthathismotherdied.4、当it作形式宾语时例句：Shemadeitclearthatshehadnothingtodowithhim．许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。5、当宾语从句前置时Thatourteamwillwin，Ibelieve．6、当that作learn，suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;由whether,if引导的宾语从句当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如：Idon'tknowif／whetherhestillliveshereaftersomanyyears．我不知道这么多年后他是否还住在这儿。但在下列情况下只能用whether，不能用if：①在具有选择意义，又有or或ornot时，尤其是直接与ornot连用时，往往用whether（if…ornot也可以使用）。如：Letmeknowwhether／ifhewillcomeornot．（＝Letmeknowwhetherornothewillcome）让我知道他是否能来。Idon'tknowwhether／ifhedoesanywashingornot．（＝Idon'tknowwhetherornothedoesanywashing．）我不知道他洗不洗衣服。Iwonderwhetherwestayorwhetherwego．我不知道我们是去还是留。②在介词之后用whether。如：I'minterestedinwhetherhelikesEnglish．我关心的是他是否喜欢英语。We'rethinkingaboutwhetherwecanfinishtheworkontime．我们正在考虑是否能按时完成这项工作。③在不定式前用whether。如：Hehasn'tdecidedwhethertovisittheoldman．他尚未决定是否拜访那位老人。Hehasn'tdecidedwhethertogobybusorbytrain．他还未决定是乘公共汽车去还是坐火车去。④whether置于句首时，不能换用if。如：Whetherthisistrueornot，Ican'tsay．这是否真的我说不上来。⑤引导主语从句和表语从句时宜用whether。如：Whethershewillcomeornotisstillaquestion．她是否能来还是个问题。⑥若用if会引起歧义时，则用whether。如：Pleaseletmeknowifyoulikethebook．可理解为：b．Ifyoulikethebook，pleaseletmeknow．你如果喜欢这本书，请告诉我只能用if不能用whether引导的宾语从句if引导条件状语从句，意为“如果”Thestudentswillgoonapicnicifitissunny.if引导否定概念的宾语从句时HeaskedifIdidn’tcometoschoolyesterday.引导状语从句evenif（即使）和asif（好象）时Hetalksasifhehasknownallaboutit.连接代词和连接副词引导的宾语从句这样的宾语从句实际上是由特殊疑问句变化而来的，语从句要用陈述句语序。用于这种结构的动词常常是：see,say,tell,ask,answer,know,decide,show,findout,imagine,suggest,doubt,wonder,discover,understand,inform,advise等。②连接代词：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。连接代词一般指疑问,但what,whatever除了指疑问外,也可以指陈述.DoyouknowwhohaswonRedAlertgame?你知道是谁赢得了红色警报的游戏么？ThebookwillshowyouwhatthebestCEOsshouldknow.这本书会告诉你最好的执行总裁该了解什么.Haveyoudeterminedwhicheveryoushouldbuy,aMotorolaorNokiacellphone?你决定好是买诺基亚还是摩托罗拉的电话了吗?③连接副词有：when,where,why,how，在句中担任状语的成分。Hedidn’ttellmewhenweshouldmeetagain.他没有告诉我什么时候我们能再见面.Couldyoupleasetellmehowyouusethenewpanel?你能告诉我怎么用这个新的操作盘吗?Noneofusknowswherethesenewpartscanbebought.没有人知道这些的新的零件能在哪里买到.三.宾语从句的语序宾语从句的语序是陈述句语序即：连接代词/副词+主语+谓语+其他成分。Idon’tknowwhattheyarelookingfor.Couldyoutellmewhenthetrainwillleave?四.宾语从句的时态时态：1。主句是一般现在时，从句根据实际情况使用任何时态。例句：Theheadmasterhopeseverythinggoeswell.主句是过去时态，从句须用过去时态的某种形式。例句：Shewassorrythatshehadn’tfinishedherworkontime.当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。例句：Theteachertoldhisclassthatlighttravelsfasterthansound.注意：运用虚拟语气的情况在表示建议suggest、advise、propose;要求demand、desire、request；决定decide;命令order、command、require;坚决主张insist;等动词后跟宾语从句，用（should）+v．（虚拟语气）Eg：Isuggestedthatyou（should）studyhard．Heorderedthatweshouldgooutatonce．虚拟语气的用法虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，虚拟语气所表示的含义不是客观存在的事实。虚拟语气的用法：1)虚拟语气用在简单句中，表示祝愿，命令。如：Mayyoubehappy.祝你幸福。Mayyouhaveagoodtime.祝愿你玩得痛快。Maythefriendshipbetweenuslastlong.祝愿我们的友情天长地久。Haveagoodjourney!祝愿你旅途愉快！Yougoout！你出去！2)虚拟语气用在宾语从句中：动词wish,suggest,order,insist,propose,等词后面的宾语从句表示的是一种虚拟语气，宾语从句中的动词动作表示的只是一种愿望、要求。如：Iwishshewouldbeonmyside.我希望她能站在我一边。IwishIcouldhelphim.我希望我能帮助他。Heinsistedthatallofusshouldbethereontimebyanymeans.他坚持要我们大家想尽办法按时去那儿。动词demand,suggest,order,insist,propose后面的从句中，"should"可以省略。如：Theteachersuggestedthatwe(should)cleantheblackboardafterclass.老师建议我们课后把黑板擦了。Heorderedthatthestudentswashtheclotheseveryweekbythemselves.他要求学生每周都要自己洗衣服。3)虚拟语气用在主语从句中：在句型"Itisimportant(necessary,strange,natural)that...."中，that后面的从句中的谓语动词用：should+动词原形，如：It'snecessarythatweshouldhaveawalknow.我们有必要出去散散步。It'snaturalthatsheshoulddoso.她这样做是很自然的。It'simportantthatweshouldtakegoodcareofthepatient.重要的是我们要照顾好病人。4)虚拟语气用在状语从句中：虚拟语气最多地用在表示条件的状语从句和表示结果的从句中。在表示与事实相反的虚拟语气时，动词有三种时态形式，即现在、过去和将来。A．与现在事实相反的：IfI(we,you,he,they)+动词过去式..ifI(he,she)were...I(we)should+动词原形。He(you,they)would+动词原形。B．与过去事实相反的：IfI(we,you,he,they)+had+过去分词I(we)should+have+过去分词。He(you,they)would+have+过去分词。IfIwereyou,Ishouldbuyit.如果我是你，我就买了它。IfIhadtime,IwouldstudyFrench.如果我有时间，我会学习法语的。IfsheknewEnglish,shewouldnotaskmeforhelp.如果她懂英语的话，她不会找我帮忙的。Ifyouhadgotupearlier,youcouldhavecaughtthetrain.如果你早一点起床，就会赶上火车的。Ifitwerefinetomorrow,Iwouldgoshopping.如果明天天气好，我就去买东西。明白了虚拟语气的用法就会明白什么时候需要用虚拟语气了，在表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，或表示的含义不是客观存在的事实时需要用虚拟语气。简化宾语从句的方法方法一：当主句谓语动词是hope，decide，wish，choose，agree，promise等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。例如：LiMinghopeshewillbebackverysoon.→LiMinghopestobebackverysoon.Wedecidedthatwewouldhelphim.→Wedecidedtohelphim.方法二：当主句谓语动词是know，learn，remember，forget，tell等动词，且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：Shehasforgottenhowshecanopenthewindow.→Shehasforgottenhowtoopenthewindow.注：当主句谓语动词是tell，ask，show，teach等动词，且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：CouldyoutellmehowIcangettothestation？→Couldyoutellmehowtogettothestation？方法三：当主句的谓语动词是order（命令），require（需要）等时，如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如：Theheadmasterorderedthatweshouldstartatonce.→Theheadmasterorderedustostartatonce.方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他形式简化。例如：Heinsistedthatheshouldgowithus.→Heinsistedongoingwithus.Thepoorboydoesn’tknowwhenandwherehewasborn.→Thepoorboydoesn’tknowthetimeandtheplaceofhisbirth.方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如：LiuPingfoundthattherewasawalletlyingontheground.→LiuPingfoundawalletlyingontheground.方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如：Itseemedthattheboysweregoingtowin.→Theboysseemedtowin.除上述方法外，还有一些特殊句式的转化，如：IfoundthatitwasdifficulttolearnEnglishwell.→IfounditdifficulttolearnEnglishwell.Soonwefoundthatthegroundwascoveredwiththicksnow.→Soonwefoundthegroundcoveredwiththicksnow.Theyfoundthattheboxwasveryheavy.→Theyfoundtheboxveryheavy.

如：①Whataclevergirlsheis!多么聪明的姑娘呀！②Whataninterestingstoryitis!多么有趣的故事呀！③Whatgoodchildrentheyare!他们是多么好的孩子呀！④Whatbeautifulflowerstheyare!多么漂亮的花呀！⑤Whatdeliciousfooditis!多么有味的食物呀！⑥Whatheavysnowitis!多么大的雪呀！二、由"how"引导的感叹句："how"意为"多么"，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是：How+adj.（adv.）+主语+谓语.

如：①Howcolditistoday!今天多么冷呀！②Hownicethepicturesare!多么漂亮的图画呀！③Howhappytheylook!他们显得多么高兴呀！④Howwellshesings!她唱得多好呀！⑤Howhardtheyareworkingnow!他们干得多么起劲呀！三、在表示同一意义时，英语感叹既可用"what"引导，也可用"how"引导。如：①Whatahotdayitis!

Howhotthedayis!多么热的天气呀！②Whattallbuildingstheyare!Howtallthebuildingsare!多么高的楼房呀！③Whatbadweatheritis!Howbadtheweatheris!多么糟糕的天气呀！④Whatbrightsunshineitis!Howbrightthesunshineis!多么明亮的阳光呀！四、感叹句在表示激动强烈的感情时，口语中常常采用省略句，其后面的主语和谓语往往略去不讲。如：①Whatafineday!多么晴朗的天呀！②Whatanhonestboy!多么诚实的孩子呀！③Whatredapples!多么红的苹果呀！④Howcool!好凉快呀！⑤Howwonderful!精彩极了！由what引导的感叹句，其句子结构可分为以下三种：1.可用句型：“What+a/an＋形容词＋可数名词单数＋主语＋谓语！”。如：Whatanicepresentitis!它是一件多么好的礼物啊！Whataninterestingbookitis!它是一本多么有趣的书啊！2.可用句型：“What＋形容词＋可数名词复数＋主语＋谓语！”。如：Whatbeautifulflowerstheyare!多么漂亮的花啊！Whatgoodchildrentheyare!他们是多么好的孩子啊！3.可用句型：“What＋形容词＋不可数名词＋主语＋谓语！”。如：Whatfineweatheritistoday!今天天气多好啊！Whatimportantnewsitis!多重要的新闻啊！由how引导的感叹句，其句子结构也分为三种：1.可用句型：“How＋形容词/副词＋主语＋谓语！”。如：Howcarefulsheis!她多么细心啊！Howfastheruns!他跑得多快啊！2.可用句型：“How＋形容词＋a/an＋可数名词单数＋主语＋谓语！”。如：Howbeautifulagirlsheis!她是个多么漂亮的姑娘啊！3.可用句型：“How＋主语＋谓语！”。如：Howtimeflies!光阴似箭！由what引导的感叹句与由how引导的感叹句有时可以转换，但句中部分单词的顺序要有所变化。如：Howbeautifulagirlsheis!＝Whatabeautifulgirlsheis!Whatdeliciouscakestheseare!＝Howdeliciousthesecakesare!有时感叹句也可以由一个单词、词组、祈使句、陈述句等构成。如：Goodidea!（好主意！）Wonderful!（太精彩了！）Thankgoodness!（谢天谢地！）Whatafunnytimetoeatbreakfast!吃早饭多么有趣啊！感叹句巧解：感叹句要看后面，即看形容词后的东东，1)若形容词后紧跟可数名词单数，就用whata/an；是不可数名词或可数名词复数，只用what。2）若形容词后后紧跟a/an/the/my/your/this/that/Tom’s等等乱七八糟的东西，想都不用想，直接用how就OK了。如：1：Whatagoodboyheis!他是个多么好的男孩啊！/\形容词单数名词2：Whatgoodboystheyare!/\形容词复数名词3：Whatcoldweatheritis!多么冷的天气啊！/\形容词不可数名词4：Howgoodtheboyis!这男孩多好啊！/\形容词乱糟糟★★★若没有形容词，而出现副词或是句子，直接用how.例：Howwellheplaystheguitar!他吉他弹得多好啊！/副词（what不可以修饰副词，看到副词直接用how）Howtimeflies!

HowfastLiuXiangruns打油诗一首:感叹句往后看形容词后是名单就用whata或whatan形后若是不可数或名复数只用what就可以形容词后乱糟糟只写how就OK了感叹句专项练习一、填入适当
