beingdone完成havingdonehavingbeendone動詞-ing形式時態(tài)和語態(tài)IrememberbeingtakentoWuhanwhenIwasaverysmallchild.(v-ing的一般被動態(tài))Sheadmittedhavingopenedthebox.(v-ing的完成式)

Howaboutthetwoofustakingawalk

downthegarden?(v-ing的復(fù)合結(jié)構(gòu))v-ing形式能在句中作主語、賓語、表語、定語、賓語補(bǔ)足語和狀語。playingfootballusedasthe

adverbial在本單元首先講解v-ing形式在句中作主語和賓語的用法。The-ingformasthesubjectandobjectv-ing形式作主語1.直接置于句首(1)Playing

tricksonothersissomethingweshouldneverdo.

捉弄別人是我們?nèi)f萬不能干的。(2)Learning

newwordsisveryimportantforme.

學(xué)習(xí)新單詞對我來說非常重要。

(3)Talkingiseasierthandoing.

說比做容易。2.用形式主語it，把真正的v-ing形式移置句尾。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。(1)ItisuselesstryingtoarguewithShylock.

和夏洛克爭辯是沒有什么用的。(2)It’sworthmakingtheeffort.

這事值得努力去做。(3)Itispleasantworkingwithyou.

跟你在一起工作是令人愉快的。It+be+awasteoftimedoing做……是浪費(fèi)時間的Itis/wasnogood/usedoing做……是沒益/用處的Itis/washardly/scarcelyworthdoing做……不值得Itis/wasworth/worthwhiledoing做……是值得的Thereisnosenseindoing

做……沒有道理常用-ing形式作主語的句型有：1.只能后接v-ing形式作賓語的動詞或短語，常見的有avoid,consider,enjoy,keep,finish,suggest,dislike,delay,escape,cannothelp,imagine,mind,miss,practise,cannotstand,excuse,fancy,giveup,putoff,risk等。

Ican’tavoidgoing.

我不能不去。v-ing形式作賓語2.既可接v-ing又可接不定式作賓語的動詞，常見的有：begin,start,continue,like,love,prefer,mean,forget,remember,hate等。IhopetheycontinuetofightforequaljusticeafterI'mgone.DianaandRoyJarvisaredeterminedtocontinueworkingwhentheyreachretirementage.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，v-ing形式表示泛指的動作，不定式表示具體的一次性動作。B.在begin/start,continue之后，用v-ing和不定式，意義無甚區(qū)別，尤其是當(dāng)主語是人的時候。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。

C.在動詞forget,remember,regret之后，用v-ing與不定式意義不同。

v-ing表示動作先于謂語發(fā)生，不定式表示后于謂語動作。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個工作試試。Ididn’tmeantomakeyouangry.我并不想讓你生氣。Yourplanwouldmeanspendinghours.你的計劃意味著要花費(fèi)幾個小時。

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)。

E.goondoing和goontodo:goondoing繼續(xù)做一直在做的事；

goontodo接著做另一件事。

Pleasegoondoingthesameexercise.

請接著做同一個練習(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。

Icouldn'tstop

laughing.我忍不住笑個不停。Istopped

to

pick

upa

letter

thatI'ddropped.我停下腳步，撿起我掉在地上的信。3.作介詞賓語下列短語中的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。

Indoingourwork,wemustpayattentiontowaysandmeans.Hewaslookingforwardtoworkingwiththenewmanager.
