第二课时Languagepoints1.holdthekeyto。。。的关键Theweatherholdsthekeytooursuccessorfailure.2.worth,worthy&worthwhileWorth用作形容词，意思是“值得的”，表示“价值多少”时，后接价值数量词，表示“值得”时，后接名词、代词或动词ing形式，worth在句中作表语时，不能单独使用，通常可用作well来修饰，而不用very.Thisnecklaceisworth$1,000.这条项链值一千美元。

Thatnovelisnotworthreading.那本小说不值得一看。

Theexhibitioniswellworthavisit.Worthy作形容词，意思是“陪得上的，值得的”，在句中可作表语和定语。作表语时，不能单独使用，后面要接of，再接名词或ing的被动形势，也可以在worthy后面直接接动词不定式。作定语时，意思是“可尊敬的，可信赖的，有价值的”。

Theplaceisworthyofavisit.Thisnovelisnotworthyofbeingread.Theschemeisworthytobeconsidered.Theworthygentlemancouldn’teventellwheatfrombarley.

那位可敬的先生连大麦和小麦都分不清。Worthwhile意思是“值得的”，可以单独用作表语。通常可用在itisworthwhile句型中，后面可接动名词，也可接动词不定式。

Thathebecamealawyermayhavebeenduetohismother’sinfluence.ItisnottruethathehasmovedtoNewYork.主语从句前的that不能省略,仅起连接作用,有时为了保持句子平衡,that从句后置,而由it作形式主语。其他类似句型还有：It+be+important/necessary/obvious+that从句It+be+reported/believed/thought/hasbeendecided+that从句It+be+apity/ashame/afact/asurprise/commonknowledge+that从句It+happens/occurs/seems/appears+that从句

宾语从句在句子中充当宾语,从句用陈述句语序,一般放在及物动词或介词之后。Idon’tknowwherethesoundcamefrom.Don'tbesatisfiedwithwhatyouhaveachieved.宾语从句Hehastoldme

(that)hewillgotoShanghaitomorrow.Hetoldme(that)hewasillandthathecouldn’tcome.command,order,suggest,advise,insist,desire,demand,beg,require,request等动词如果后面加上宾语从句的话,从句谓语局部必须用shoulddo。Iinsistthatshe(should)doherworkalone.Thecommanderorderedthattroops(should)setoffatonce.it+从句介词+it+从句it+adj.+从句it+介词短语+从句it+n.+从句it+过去分词+从句It形式宾语主语+谓语Ihateitwhenpeoplespeakwiththeirmouthsfull.I’llseeto(保证)itthateverythingisreadyintime.Hemadeitclearthathewouldleaveofficesoon.WemustbearitinmindthatweareChinese.Wethoughtitapitythathefailedagain.Ihearditsaidthathehadgonehome.当从句放在系动词be,look,remain,seem等后即构成表语从句。其根本结构为:主语+系动词+that从句。ThetroubleisthatIhavelosthisaddress.Itseemedthatthenightwouldneverend.Thefactisthatwehavelostthegame.That’sjustwhatIwant.Thisiswhereourproblemlies.Thatiswhyhedidn’tcometothemeeting.Itlooksasifitisgoingtorain.同位语从句同位语从句是对与之同位的名词中心词作进一步解释,能接同位语从句的常见名词有:idea,fact,news,belief,hope,evidence,opinion,problem,truth,answer,proposal,theory,decision,discovery,problem,thought,understanding等。Thenewsthatwewonthegameisexciting.Ihavenoideawhenhewillcomebackhome.WordcametohimthatMaryhadprobablyfallenill.Theyareinvestigatingthequestionwhetherthemanistrustworthy.Thefactthatwetalkedaboutisveryimportant.(定语从句)Thefactthathesucceededintheexperimentpleasedeverybody.(同位语从句)

whether与if在名词性从句中的用法区别if一般只用于引导宾语从句，而whether可引导包括宾语从句在内的其他名词性从句。

连词whether引导主语从句、表语从句时不能用if来替换。Whetherhewillattendthemeetingisuncertain.Thequestioniswhetherhewillcome.宾语从句中,whether常与ornot搭配,可以说whetherornot,而不说ifornot.Idon'tcarewhetherornotshewillattendthemeeting.whether可用在介词后,或带to不定式前,if那么不可。Shedoesn’tknowwhethertogetmarriednoworwait.Ihaven’tsettledthequestionofwhetherI’11gobackhome.某些动词后面(如discuss)只能用whether,不用if。Wediscussed
