高一英语同步测控：Unit5Canada—TheTrueNorth第3课时Grammar课前预习本课语法呈现观察以下课文中的句子，分析划线部分的语法功能。Thethoughtthattheycouldcrossthewholecontinentwasexciting.TheyforgetthefactthatCanadais5,500kilometresfromcoasttocoast.ThegirlsweresurprisedatthefactthatoceanshipscansailuptheGreatLakes.要点精讲：同位语从句在句子中作同位语的从句称为同位语从句。同位语从句是名词性从句的一种，一般由连词that引导，常放在fact,news,idea,truth,hope,problem,discovery,information,word,message,thought,suggestion等名词的后面，说明该名词的具体内容。e.g.1)Thefactthathedidn’tcomeshowsthathehasbrokenhisword.2)Soonwordcamethattheyshouldannouncetheresultsoftheexam.同位语从句是名词性从句的一种，同学们在学习时应掌握以下几点：1.同位语从句与于定语从句的区别:同位语从句起补充说明作用，that是连词，在从句中无意义,不充当句子成分，但不能省略;定语从句起修饰限定作用，that是关系代词，在从句中充当主语或宾语，作宾语时可省略。e.g.1)Thenewsthattheyhadwonthebattlesoonspreadoverthewholecountry.(同位语从句)2)Thenewsyoutoldmeyesterdaywasreallydisappointing.(定语从句)2.同位语从句也可由连接代词who，which，what和连接副词where，when，why，how等引导。e.g.Thequestionwhoshoulddotheworkrequiresconsideration.Wehaven’tyetsettledthequestionwherewearegoingtospendoursummervacation.It’saquestionhowhedidit.3.同位语从句用陈述语序。4.一般情况下，主从句的时态应保持一致。担当从句表示的是客观事实或普遍真理时，从句仍然用一般现在时。e.g.Theywereallverymuchworriedoverthefactthatyouweresick.对于你生病这件事，他们都很着急。Magellan'smen'sreturnfromthevoyageprovedthetruththattheearthisround.麦哲伦的海员们的航海回归证实了地球是圆的这一真理。5.表示"命令、建议、要求"的名词order，demand，suggestion等后接同位语从句时，从句的谓语要用虚拟语气，即"should+动词原形".e.g.Theymainlydiscussedthesuggestionthatabigdam(should)bebuiltthere.他们主要讨论了在那里建一个大坝这个建议。6.表达”是否”意义时,要用whether而不用if引导同位从句Ihavenoideawhetherheisinterestedintheplan.实战演练名词性从句一.用适当的连接代词或连接副词填空1.Theproblem_______hecan'tcometohelpusworriesusalot.2.Ihavenoidea_______hewillreturn.3.Ihavenoinformation_______hewentcampinglastSunday.4.Heexpressedtheopinion___Tomshouldbemademanagerofthefactory.5.Theproblemis_______theyhaverunoutoffood.6.There'snodoubt_______hewaskilledintheaccident.7.There'sgreatdoubt_______hedidsoornot.8.Hetoldmethenews_______hishousehadjustburneddown.9.Hetoldmethenewsof_______househadjustbeenburneddown.10.Wordcame_______thePresidentoftheUSAwouldinspectthearmy.二.句型转
