IfIwereyou,Iwouldinvitehimtotheparty.假如我是你,我會邀請他參加聚會。Iwouldhavearrivedmuchearlier

if

Ihadnotbeencaughtinthetraffic.假如沒有堵車,我會到早一點兒。8/54其它引導詞:1.unlessconj.除非,若不,除非在……時候e.g.Youwillfailtoarrivethereintime

unlessyoustartearlier.假如你不早點動身,你就不能及時趕到那兒。

Unless

itrains,thegamewillbeplayed.除非下雨,比賽將照常進行。9/542.oncondition(that)...在……條件下,假如oncondition(that)...引導條件從句是主句事件發(fā)生前提條件或唯一條件。e.g.Icantellyouthetruthonconditionthatyoupromisetokeepasecret.我能夠告訴你真相,條件是你答應保守秘密。10/54Youcangoswimmingoncondition(that)youdon’tgotoofarfromtheriverbank.你只有在不遠離河岸條件下才能夠下水游泳。11/54e.g.Supposingitrains,shallwecontinuethesportsmeeting?倘若下雨,我們運動會還要繼續(xù)舉行嗎?

Supposingsomethingshouldgowrong,whatwouldyoudothen?假如出了什么問題,你準備怎么辦?3.supposingconj.假如,假如supposing引導條件從句表示一種___________。假設條件12/544.providedconj.假如,除非,以……為條件provided(that)+從句,表示一個假設條件。e.g.Hewillsignthecontract

providedweoffermorefavorableterms.假如我們提出更優(yōu)惠條件,他就會在協(xié)議上簽字。13/54Hewon’tbeagainstusinthemeetingprovidedthatweaskforhisadviceinadvance.假如我們提前征求一下他意見,他就不會在會上反對我們。14/54另外還有incase,as/solongas等。e.g.Incaseitrains,donotexpectme.如若下雨,就不要等我了。Aslongasyoupromisetocome,I’llwaitforyouuntilyoucome.只要你答應,我就等你來。15/54從上述例句能夠看出if,unless,oncondition(that),supposing,provided等詞引導條件狀語從句,主從句條件關(guān)系分明,結(jié)構(gòu)清楚。在條件狀語從句中,用___________代替___________,_____________代替_____________。

普通現(xiàn)在時普通未來時普通過去時過去未來時16/54但有些句子,雖沒有含條件關(guān)系連詞,卻也隱含著條件關(guān)系,這些句子慣用一些詞,如butfor,without等引出一個介詞結(jié)構(gòu)來表示條件,條件經(jīng)常是虛擬,或與事實相反假設。butfor若非,要不是17/54e.g.Butfortherain,weshouldhaveapleasantjourney.要不是下雨,我們旅行必定會很愉快。

Butforyourhelp,weshouldnothavefinishedintime.要不是你幫忙,我們必定不能及時完成任務。18/54Findmoreexamplesofsentenceswithiforwheninthepassage.1)Ifourrighthandisbusygreetingsomeone,itcannotbeholdingaweapon.2)Ifyoushakehandswithsomeone,youshowyoutrustthem.19/543)Weshakehandswhenwemakeadeal.4)Whenwegreetsomeone,weputtherighthandovertheleftandbowslightly.20/54a.

though,although表示“即使,縱然”之意。在普通情況下能夠交換使用。

在口語中,though較常使用,although比though正式,二者都可與yet,still或nevertheless連用,但不能與but連用。

讓步狀語從句引導詞:32/54e.g.Though/Althoughhewaswornout,(still)hekeptonworking.即使他已經(jīng)精疲力竭,但依然繼續(xù)工作。Though/Althoughheisveryold,(yet)heisquitestrong.

他即使年紀大了,身體還很健壯。33/54注意:although引導讓步狀語從句位于主句之前情況較多,though引導讓步狀語從句可位于主句之前或主句之后。

e.g.Shepassedtheexamination

though

shehadnotstudiedveryhard.她即使不用功學習,考試卻及格了。34/542.Objectasyoumay,I’llgo.=Though/Althoughyoumayobject,I’llgo.縱使你反對,我也要去。Hardas/thoughheworks,hemakeslittleprogress.=Thoughheworkshard,hemakeslittleprogress.盡管他學習很努力,但幾乎沒取得什么進步。35/54【歸納】as,though表示“即使……不過”,“縱使……”之意。

as引導讓步狀語從句必須以___________形式出現(xiàn),被倒裝部分能夠是表語、狀語或動詞原形,though間或也用于這么結(jié)構(gòu)中,但although不能夠這么用。部分倒裝36/54Childas/thoughhewas,heknewwhatwastherightthingtodo.=Thoughhewasachild,heknewwhatwastherightthingtodo.即使他是一個孩子,但他知道該做什么。Fastasyouread,youcan’tfinishthebooksosoon.縱然你讀得快,你也不能這么快讀完這本書。37/543.evenif,eventhough表示“即使……”,“縱使……”之意。這兩個復合連詞意思基本相同，它們?？山粨Q使用,但意義有細微差異。evenif引導讓步從句含有強烈假定性,而eventhough引導讓步狀語從句時,是以從句內(nèi)容為先決條件,也就是說,說話人必定了從句事實。

38/54e.g.We’llmakeatripevenif/thoughtheweatherisbad.即使天氣不好,我們也要作一次旅行。Evenifheispoor,sheloveshim.=Hemaybepoor,yetsheloveshim.即使他很窮,但她還是愛他。Eventhoughheispoor,sheloveshim.=Heispoor,yetsheloveshim.盡管他很窮,但她還是愛她。39/544.

whether...or...表示“不論是否……”,“不論是……還是……”之意。由這一個復合連詞引導讓步狀語從句意在說明正反兩個方面可能性都不會影響主句意向或結(jié)果。40/54e.g.You’llhavetoattendtheceremony

whetheryou’refreeorbusy.不論你忙不忙,都要參加這個儀式。

Whetheryoubelieveitornot,it’strue.不論你是否相信,這都是真。41/54“nomatter+疑問詞”或“疑問詞-ever”含義為“……都……;不論……都……”,它們引導讓步狀語從句能夠交換。

e.g.Nomatterwhathappened,hewouldnotmind.=Whateverhappened,hewouldnotmind.不論發(fā)生了什么,他都不會介意。42/54Nomatterwhoyouare,youmustkeepthelaw.=Whoeveryouare,youmustkeepthelaw.不論你是誰,你都要遵紀遵法。43/54但“nomatter+疑問詞”結(jié)構(gòu)只能引導讓步狀語從句,而“疑問詞-ever”還能夠引導名詞性從句。e.g.Whatever(=Nomatterwhat)yousay,Iwon’tbelieveyou.(Whatever引導讓步狀語從句)44/54不論你說什么,我都不會相信你。I’lleatwhatever(≠nomatterwhat)yougiveme.(whatever引導賓語從句)

你給我吃什么,我就吃什么。Whoevercomeswillbewelcome.(Whoever引導主語從句)

不論誰來都受到歡迎。45/54另外,有時while也能夠引導讓步狀語從句,但普通要位于句首。e.g.WhileIlikethecolour,Idon’tliketheshape.我即使喜歡那顏色,但不喜歡那形狀。46/541.
