newsonTVhasbecomearoutineforme.在電視上看新聞已經(jīng)成了我的一種日常習(xí)慣。Going

to

Hangzhoubytraintakesabout16hours.乘火車去杭州要16個小時。Asking

awoman’sageisimpoliteinourcountry.在我們國家問一個女人的年齡是不禮貌的。

2.-ing形式作主語時常后置,此時須用it作形式主語,用形容詞或名詞作表語。常見的名詞或名詞短語有:nouse,nogood,fun,hardwork,ahard/difficultjob,awasteoftime等;形容詞有:dangerous,worthwhile,useless等。如:It’snousemakinganexcuseforthis.為這件事找借口是沒有用的。It’sawasteoftimetalkingaboutsuchauselessthing.談?wù)撨@樣無用的事情簡直是浪費(fèi)時間。It’sdangerousswimmingintheseaonwindydays.有風(fēng)的天氣在海里游泳是危險的。Itisworthwhilediscussingthequestion.這個問題值得討論。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…”。如：若要人不知,除非己莫為。Thereisnohidingofevilbutnottodoit．這種事開不得玩笑。

Hereisnojokingaboutsuchmatter.無法知道他什么時候離開Therewasnoknowingwhenhewouldleave.動名詞與不定式做主語時的比較：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。如：還是個孩子的時侯,她就覺得探視病人是一種責(zé)任,也是一種愉悅。Asachild,shefeltthatvisitingsickpeople

wasadutyandapleasure．到美國人家里做客對我來說將是一個極好的經(jīng)歷。Being

aguestinanAmericanhomewillbeagoodexperienceforme.一直不做就是作惡。

Doingnothingisdoingill．他說:“繼續(xù)這樣下去是無用的。”

Hesaid,“To

like

thisisnouse.”我很榮幸被邀請參加這個晚會。

It’sanhonorformeto

be

invitedtotheparty．歸納:常用-ing形式作主語的句型有：It+be+awasteoftimedoing

做……是浪費(fèi)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…無意義我們不知道要去哪兒。Therewasnoknowingwherewewouldgo.做這件傻事毫無意義。Thereisnopoint

doing

suchasillything.注意:Thereisnoneedtodosth

干……沒必要,在此句式中todo不可換為doing.沒有必要告訴她。Thereisnoneedtotellher.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。我姐姐病了,使我很擔(dān)心。Mysister’sbeingillmademeworried.你正確未必就意味著我錯了。Yourbeingrightdoesn’tnecessarilymeanmybeingwrong.二、動名詞用作賓語

動名詞作賓語有兩種情況。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：我不能不去。Ican’tavoidgoing．你是否考慮過找一位摯友?Haveyouconsidered

looking

foronespecialfriend?我們必須設(shè)法避免犯同樣的錯誤。Wemusttrytoavoidrepeatingthesamemistake．晚飯后你想和我一起散步嗎?Doyoufeel

like

havingawalkwithmeaftersupper?人們?nèi)滩蛔〕靶δ莻€愚蠢的人。Peoplecouldn’t

help

laughingfoolishman．

這類動詞還有:excuse,fancy,giveup,putoff,risk,insiston,lookforward,feellike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。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。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。

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,

如：我記得我已把信寄了。Irememberpostingtheletter．我會記著去寄信的。I’llremember

to

posttheletter．我永遠(yuǎn)不會忘記見到過那位著名作家。Ishallneverforget

seeingthefamouswriter．不要忘了給你母親寫信。Don’tforget

to

writetoyourmother．我真后悔沒趕上那次報告會。Iregret

missingthereport．我遺憾地告訴你我不能接受你的建議。Iregret

to

sayIcan’ttakeyouradvice．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)。如:我們必須設(shè)法及時把一切搞好。Wemusttrytogeteverythingdoneintime．我們用別的方法做這工作試試。

Let’stry

doingtheworkinginsomeotherway．我并不想叫你生氣。Ididn’tmean

to

makeyouangry．你的計劃意味著要花費(fèi)幾個小時。Yourplanwouldmean

dotheotherexercise．F.stopdoing與stoptodo:Stopdoing停止做，stoptodo停下正在干的事去干另一件事。如:我們停止了交談。Westopped

talking．我們停了下來去談話。Westopped

to

talk．goondoing繼續(xù)做原來做的事goontodo接著做另一件事

meandoing意味著要做某事meantodo想要做某事stopdoing停止做某事stoptodo停下來(別的事)開始做某事trydoing試著做某事trytodo努力做某事beusedtodoing習(xí)慣于做某事

beusedtodo被用來做某事can'thelpdoing禁不住做某事can'thelptodo不能幫助做某事3.作介詞賓語動名詞可與介詞一起構(gòu)成介詞短語。A.介詞+動名詞,
