單項填空
①Itwasyourtimelyhelpthatweaccomplishedthetaskontime.（2010?01?山西運城檢測）
A.BecauseB.thankC.thankstoD.as
②thenewpolicy,wearenowhavingahappylife.（2010?01?安徽亳州檢測）
A.ThankstoB.Because
C.ForD.Thanksfor
①解析：選C。because和as雖然也表示“因為，由于”，但后面需接句子，而句中是短語，故應(yīng)用thanksto。句意為：幸虧你及時幫忙，我們才按時完成了任務(wù)。
②解析：選A。考查近義詞辨析。thanksto意為“多虧了”；because后應(yīng)加句子;for表示補充說明的原因。

wouldrather＋從句時，從句要用虛擬語氣，用動詞的過去時表示。
wouldratherhavedone本想做……（而實際上未做）
高手過招
單項填空
①—Shallwegoskatingorstayathome?
—Whichdoyourself?（2010?01?江西南昌檢測）
A.doyouratherB.wouldyourather
C.willyouratherD.shouldyourather
②I’dratherthebasketballmatchlastnight.Otherwise,Iwouldhavefinishedmypaperworkbynow.
（2010?01?江蘇徐州檢測）
A.nothavewatchedB.notwatch
C.hadn’twatchD.haven’twatch
①解析：選B?？疾閣ouldratherdosth.這一結(jié)構(gòu)的用法。而do,will和should都不能與rather搭配。wouldrather(not)dosth.意為“寧愿（不愿意）做某事”。
②解析：選A。wouldrathernothavedone意為“本不想做……（實際卻做了）”。后一句句意為：否則我現(xiàn)在已經(jīng)完成了我的文件。所以前句表示“本不想看球賽卻看了”，故選A。

注意：leadto中的to為介詞，該短語后可跟名詞或動名詞。

動名詞一、概述?和不定式一樣,動名詞也是非謂語動詞的一種,它通常由動詞原形加-ing構(gòu)成。動名詞有主動和被動兩種語態(tài),有一般式,完成式和進(jìn)行式三種形式。如下表所示:

動名詞仍保留有動詞的特征,可以和自己的邏輯主語、賓語和狀語等構(gòu)成動名詞短語。動名詞具有名詞的功能,在句中可以充當(dāng)主語、賓語、表語、定語等成分。?二、動名詞的時態(tài)和語態(tài)形式?1.動名詞的時態(tài)形式?①一般式?動名詞的一般式表示動作或狀態(tài)與謂語動詞的動作同時發(fā)生,或者表示一種無時間性限制的經(jīng)常性、習(xí)慣性的動作或狀態(tài)。?HeenjoyswritinglettersinEnglish.?他喜歡用英語寫信。?Manyyoungpeoplelikeplayingfootball.?許多年輕人喜歡踢足球。?②完成式?動名詞的完成式表示動作或狀態(tài)先于謂語動詞的動作或狀態(tài),如:?Theyregrethavingbeenunabletohelpyou.?他們?yōu)闆]能幫上你的忙而遺憾。?Afterhavingwrittentheletter,hewenttopostit.?他寫完信,就去寄它了。?Sheregrettedhavingmissedthefilm.?她后悔沒有看到那部電影。?③完成進(jìn)行式?動名詞的完成進(jìn)行時表示動作發(fā)生于謂語動作之前,并一直持續(xù)到謂語動詞的動作發(fā)生之時,或繼續(xù)。如:?Forgivemeformyhavingbeeninterruptingyousomuch.?原諒我打擾你這么久。2.動名詞的被動式?當(dāng)動名詞的邏輯主語是動名詞動作的承受者時,用被動式。如:?Heclimbedthroughthewindowwithoutbeingseen.?他從窗口爬進(jìn)去,沒有被人發(fā)現(xiàn)。?Sheneedstoworkwithoutbeingdisturbed(=withoutpeopledisturbher).?她要在無人干擾的情況下才能工作。?動名詞的被動語態(tài)分成一般式和完成式兩種。如:?Therailwayisintheprocessofbeingconstructed.?鐵路在興建中。?AfterhavingkeptaprisonerintheBastilleformanyyears,DrManettehadrecentlybeensetfree.?曼奈特醫(yī)生被關(guān)在巴士底監(jiān)獄許多年后,最近獲釋。?特別提示:-ing形式的主動形式表示被動意義?在want,need,deserve,require等動詞后,總是用-ing形式的主動形式表示被動意義,相當(dāng)于“tobe+過去分詞”。如:?Mywatchneedsrepairing(=toberepaired).?我的手表需要修理。?Thehousewantscleaning.這房屋需要打掃。?在worth這個形容詞后情形也是這樣。如:?Thefilmisworthseeing.這部影片值得一看。?Theplaceisworthvisiting.那個地方值得一游。?三、動名詞的否定式?動名詞的否定式通常是在動名詞前加否定詞not。例如:?Iapologizeformynothavingkeptpromise.?我沒能遵守諾言,十分抱歉。?Iregretnotbeingabletohelpyou.?我很抱歉不能幫助你。?1.作主語?動名詞作主語時,句子有兩種形式:?(1)動名詞直接置于句首主語的位置上。?Playingtricksonothersissomethingweshouldneverdo.?捉弄別人是我們?nèi)f萬不能干的。?Learningnewwordsisveryimportantforme.?學(xué)習(xí)新單詞對我來說非常重要。?Talkingiseasierthandoing。說比做容易。?(2)用形式主語it,把真正的主語——動名詞結(jié)構(gòu)移置句尾。但這種句子形式有一定的限制,作表語的只能是某些形容詞或少數(shù)名詞,如useful,useless,good,fun，nouse,worth等。例如:?ItisuselesstryingtoarguewithShylock.?和夏洛克爭辯是沒有什么用的。?It’sworthmakingtheeffort.?這事值得去做。?Isitanygoodtryingtoexplain??想再解釋一次有好處嗎??Itispleasantworkingwithyou.?跟你在一起工作是令人愉快的。?(3)在therebe結(jié)構(gòu)中作主語,這種結(jié)構(gòu)的意思相當(dāng)于“Itisimpossibletodo...”。例如:?Thereisnohidingofevilbutnottodoit.?若要人不知,除非己莫為。?Thereisnojokingaboutsuchmatter。?這種事開不得玩笑。?Therewasnoknowingwhenhewouldleave.?無法知道他什么時候離開。?注意:動名詞與不定式作主語時的比較:?動名詞表示的動作通常是一個泛指的動作,不定式則通常表示具體的動作。例如:?Asachild,shefeltthatvisitingsickpeoplewasadutyandapleasure.?還是個孩子的時候,她就覺得探視病人是一種責(zé)任,也是一種愉悅。?BeingaguestinanAmericanhomewillbeagoodexperienceforme.?到美國人家里做客對我來說將是一個極好的經(jīng)歷。?Doingnothingisdoingill.?什么也不做就是作惡。?Hesaid,“Togoonlikethisisnouse.”?他說:“繼續(xù)這樣下去是無用的。”?It’sanhonourformetobeinvitedtotheparty.?我很榮幸被邀請參加這個晚會。?歸納:常用-ing形式作主語的句型有:?It+be+awasteoftimedoing做……是浪費時間的?Itis/wasnogood/usedoing做……是沒用處的?Itis/washardly/scarcelyworthdoing做……不值得?Itis/wasworth/worthwhiledoing做……是值得的?Thereisnodoing無法……,不允許……?Thereisnosenseindoing做……沒有道理?Thereis/wasnousedoing干……無意義?Thereis/wasnothingworsethandoing沒有比……更糟的?Thereis/wasnopointdoing干……無意義?Therewasnoknowingwherewewouldgo.?我們不知道要去哪兒。?Thereisnopointdoingsuchasillything.?做這件傻事毫無意義。?注意:Thereisnoneedtodosth.干……沒必要,在此句式中todo不可換為doing。?Thereisnoneedtotellher.沒有必要告訴她。?提示:當(dāng)動名詞用作主語時,其邏輯主語由形容詞性物主代詞和名詞所有格構(gòu)成。?Mysister’sbeingillmadeweworried.?我姐姐病了,使我很擔(dān)心。?Yourbeingrightdoesn’tnecessarilymeanmybeingwrong.?你正確未必就意味著我錯了。2.作動詞的賓語?動名詞作賓語有兩種情況。一是有些動詞只能后接動名詞作賓語;二是有些動詞既可后接動名詞也可后接不定式作賓語。?（1）只能后接動名詞作賓語的動詞,常見的有avoid,consider,enjoy,keep,finish,suggest,dislike,delay,escape,cannothelp,imagine,mind,miss,practise,cannotstand等。如:?Ican’tavoidgoing.我不能不去。?Haveyouconsideredlookingforonespecialfriend??你是否考慮過找一位摯友??Wemusttrytoavoidrepeatingthesamemistake.?我們必須設(shè)法避免犯同樣的錯誤。?Doyoufeellikehavingawalkwithmeaftersupper??晚飯后你想和我一起散步嗎??Peoplecouldn’thelplaughingfoolishman.?人們?nèi)滩蛔〕靶δ莻€愚蠢的人。?這類動詞還有:excuse,fancy,giveup,putoff,risk等。?（2）既可接動名詞又可接不定式作賓語的動詞,常見的有:begin,start,continue,like,love,prefer,by,mean,forget,remember,hate等。?A.在like,love,hate,prefer等動詞之后,用-ing或不定式意義上沒有什么不同,只是側(cè)重點有些不同,動名詞表示泛指的動作,不定式表示具體的一次性動作。例如:?Iconsideredgoing,butIhavethiscompositiontowrite.?我考慮要去,可是我要寫這篇作文。?Ienjoylearningaboutnewthingsfrompoliticstosportsandmusic.?我喜歡從政治、體育及音樂等方面學(xué)習(xí)新的事情。?Webelievethatmanymorepeoplewillprefertotravelbyair.?我們相信將會有更多的人喜歡乘坐飛機旅行。?在wouldlike／love／prefer之后,只能用不定式。例如:?I’dprefertodothattomorrow.這事我想明天再做。?I’dliketodosomeshopping,butnotduringtheday.?我倒是想去購物,但又不想白天去。?I’dlikeyoutomeetDrZhang.?我想讓你見一見張醫(yī)生。?Oh,Iwouldlovetobeacontestant.?噢,我倒是想做個參賽者。?B.在begin/start,continue之后,用動名詞和不定式,意義無甚區(qū)別,尤其是當(dāng)主語是人的時候。例如:?Jazzstarteddevelopinginthe1920sintheSouthernStates.?20年代爵士音樂在美國南部各州開始發(fā)展。?Theshipstartedtoleakandbegintofillwithwater.?船體開始出現(xiàn)漏洞,并開始進(jìn)水。?Hankstartedtowalkthroughthecarriagestogetbacktohisseat.?漢克開始走回他自己坐的車廂。?Journalistshavetostopworkingononestoryandstartworkingimmediatelyontheimportantnewone.?新聞記者不得不停下手中所寫的,立刻開始寫最新的重要新聞。?當(dāng)begin/start與see,think,feel,understand等動詞連用時,用不定式。例如:?Theybegantounderstandhowimportanttheforestis.?他們開始明白森林有多么重要。?begin/start用進(jìn)行式時,只能后接不定式。例如:?Iwasbeginningtowonderifitwaseasyenoughtogoontheclimbing.?我開始想繼續(xù)往上爬會不會越來越難。?I’mstartingtoputonweightagain.?我又開始長胖了。?C.在動詞forget,remember,regret之后,用動名詞與不定式意義不同。動名詞表示動作先于謂語發(fā)生,不定式表示后于謂語動作,例如:?Irememberpostingtheletter.?我記得我已把信寄了。?I’llremembertoposttheletter.?我會記著去寄信的。?Ishallneverforgetseeingthefamouswriter.?我永遠(yuǎn)不會忘記見到過那位著名作家。?Don’tforgettowritetoyourmother.?不要忘了給你母親寫信。?Iregretmissingthereport.?我真后悔沒趕上那次報告會。?IregrettosayIcan’ttakeyouradvice.?我遺憾地告訴你我不能接受你的建議。?D.在try,mean之后,意義各不相同,如trytodo(設(shè)法),trydoing(試試),meantodo(打算,有意要做),meandoing(意思是,意味著)。例如:?Wemusttrytogeteverythingdoneintime.?我們必須設(shè)法及時把一切搞好。?Let’strydoingtheworkinginsomeotherway.?我們用別的方法做這工作試試。?Ididn’tmeantomakeyouangry.?我并不想叫你生氣。?Yourplanwouldmeanspendinghours.?你的計劃意味著要花費幾個小時。?E.goondoing和goontodo?goondoing繼續(xù)做一直在做的事;goontodo接著做另一件事。例如:?Pleasegoondoingthesameexercise.請接著做這同一個練習(xí)。?Pleasegoontodotheotherexercise.請做另外一個練習(xí)。?F.stopdoing與stoptodo?stopdoing停止做,stoptodo停下正在干的事去干另一件事。如:?Westoppedtalking.我們停止了交談。?Westoppedtotalk.我們停了下來去談話。3.作介詞的賓語?動名詞可與介詞一起構(gòu)成介詞短語。?A.介詞+動名詞,如:?We’vegottothinkofwaysofchangingpeople’shabits.?我們得想些辦法改變?nèi)藗兊牧?xí)慣。?Iapologizeforbeingsoangrywithyou.?我向你道歉,剛才對你那樣生氣。?Afterbeingawayforseveralyears,itisastrangeexperiencetoreturntotheplaceyouwerebornandbroughtup.?離開幾年之后再回到你生長的地方,感覺有點怪。?B.動詞+介詞+動名詞,例如:?Iinsistontakingproperfoodforthisexpedition.?我堅持為這次出行帶足需要的食物。?Insteadofsmiling,eachofthemmadeaface.?同學(xué)們臉上沒有笑容,相反都做了怪臉。?Shewasveryinterestedinworkingforourcompany.?她對為我們公司工作很感興趣。?下列短語中的to都是介詞,所以后面跟名詞或-ing形式:devoteto,objectto,payattentionto,getdownto,leadto,lookforwardto,stickto,beusedto等。?Unit2
