B．wasreachedC．willreach D．willhavereached解析：選A句意：盡管之前進(jìn)行了多輪談判，但到目前為止雙方還沒有達(dá)成任何協(xié)議。根據(jù)句中的時間狀語sofar“到目前為止”可知用現(xiàn)在完成時。主語agreement與reach為被動關(guān)系，根據(jù)句意可知選A。三、被動語態(tài)的特殊結(jié)構(gòu)形式1．情態(tài)動詞(may,might,can,could,should,oughtto,must)＋be＋過去分詞，構(gòu)成被動語態(tài)。Nowadays,solarenergycanbeusedtoproduceelectricityinmanycountries.現(xiàn)在太陽能在許多國家可以被用來發(fā)電。Arealsenseofachievementandhappinessmaybefelt.一種真正的成就感和幸福感可能被感覺到。Thepollutionmustbestopped.必須停止污染。[即時演練2](1)句型轉(zhuǎn)換(每空一詞)①TeacherscanuseRealCineintheclassroom.→RealCinecanbeusedintheclassroombyteachers.②Youneedn'tdoitnow.→Itneedn'tbedone(byyou)now.(2)Coalcan________toproduceelectricityforagricultureandindustry.A．haveused

B．musttakecareofC．mustbelookedafter D．mustlookafter解析：選C句意：這位老人手術(shù)后很虛弱，所以必須被照顧。由句意可知此處表示被照顧，故C項正確。A項需改為“mustbetakencareof”。四、使用被動語態(tài)應(yīng)注意的幾個問題1．主動形式表示被動意義(1)當(dāng)feel,look,smell,taste,sound等系動詞后面接形容詞/名詞構(gòu)成系表結(jié)構(gòu)時；當(dāng)cut,read,sell,wear,write,wash,cook,shut,dry,drink等表示某種屬性且?guī)в行揎椪Z時；當(dāng)動詞表示“開始、結(jié)束、運動”等意義時。Thefishsmellsgood.魚聞起來很香。Thebookwrittenbythatfamouswritersellsverywell.那位著名作家寫的書很暢銷。(實際上是被賣得暢銷)Cottonfeelssoft.棉花摸起來很柔軟。Thesecupscleaneasily.這些杯子很容易洗。Themuseumdoesn'topenonMonday.博物館星期一不開放。[名師點津]下面的短語經(jīng)常使用主動語態(tài)：comeout,comeintobeing,gooff,runout,giveout,givein。(2)want,require,need后面的動名詞用主動形式表示被動意義，或用不定式的被動形式。Theseflowerswant/require/needwatering/tobewatered.這些花需要澆水。(3)“be＋adj.＋todo”中，不定式的邏輯賓語是句子的主語，用主動形式表示被動含義。Heisn'teasytogetalongwith.他不容易相處。[即時演練5](1)翻譯句子①我的房子需要修理了。My_house_needs_repairing/to_be_repaired.②老年人需要細(xì)心照料。The_old_require_looking_after_carefully.③這個問題容易回答。This_question_is_easy_to_answer.④這個包背起來很重。The_bag_is_very_heavy_to_carry.(2)ThebeefIboughtfromthedeliisveryfreshand_______.A．iseasilycut B．cutseasyC．cutseasily D．iscuteasy解析：選C句意：我從熟食店買的牛肉很新鮮，而且容易切割。cut表示“可切割”時，用主動形式表示被動的含義，所以排除A、D兩項；修飾動詞應(yīng)該用副詞形式，故選C項。2．含被動語態(tài)的句型及其轉(zhuǎn)換“Itis＋過去分詞＋that從句”這一句型的常見形式有：Itisbelievedthat...人們相信……Itissaidthat...據(jù)說……Itishopedthat...人們希望……Itisthoughtthat...人們認(rèn)為……Itisreportedthat...據(jù)報道……Itis(well)knownthat...眾所周知……Itissupposed/consideredthat...人們認(rèn)為……Itisagreedthat...人們一致同意……Itisjudgedthat...據(jù)判斷……Itisprovedthat...據(jù)證實……Itisestimatedthat...據(jù)估計……Itisbelievedthathehasbeenworkinghard.大家相信他一直努力工作。Itisreportedthathehasbeendrivingwhiledrunk.據(jù)報道，他醉酒駕車。[名師點津]以上句式大多數(shù)可轉(zhuǎn)換為Sb./Sth.issaid/believed/thought/reportedto...句型。Itissaidthatsheistherichestwomaninthecity.→Sheissaidtobetherichestwomaninthecity.據(jù)說她是這個城市里最富有的女人。[即時演練6](1)句型轉(zhuǎn)換(每空一詞)①Peoplesayyouarearealhero.→Youaresaidtobearealhero.→Itissaidthatyouarearealhero.②PeoplesaidEdisonhadinventedthefirstlight.→Edisonwassaidtohaveinventedthefirstlight.→ItwassaidthatEdisonhadinventedthefirstlight.(2)________intheregulationsthatyoushouldnottellotherpeoplethepasswordofyoure-mailaccount.A．Whatisrequired B．WhatrequiresC．Itisrequired D．Itrequires解析：選C句意：章程中要求你不應(yīng)該把你的郵件賬號的密碼告訴他人。此句中it作形式主語，代替后面的that從句，而且that從句內(nèi)容與require構(gòu)成被動關(guān)系，故C項正確。3．被動語態(tài)和系表結(jié)構(gòu)的區(qū)別“動詞be＋過去分詞”可能是被動語態(tài)，也可能是系表結(jié)構(gòu)，其區(qū)別是：被動語態(tài)表示動作，句子主語是動作的承受者；系表結(jié)構(gòu)說明主語所處的狀態(tài)，過去分詞相當(dāng)于形容詞。Thecupwasbrokenbymybrother.(被動語態(tài))這個茶杯是被我弟弟打碎的。Thecupisbroken.(系表結(jié)構(gòu))這個茶杯破了。[即時演練7](1)判斷下列句子屬于A(系表結(jié)構(gòu))還是B(被動語態(tài))①Thegateofthegardenwaslockedbythegirl.__B__②Thegateofthegardenwaslocked.__A__③Iaminterestedincomputerstudies.__A__④Theoldmanwassurroundedbythechildren.__B__⑤Thispicturewasdrawnlongago.__B__(2)Shortlyafterwe________，awaitercameovertoourtablewithasmile.A．seated

B．wererewardedC．willreward D．willberewarded解析：選D句意：學(xué)生們一直在努力學(xué)習(xí)功課，他們的付出最終會收獲成功的。由前面的現(xiàn)在完成進(jìn)行時可排除A、B兩項；再由theirefforts與reward之間是被動關(guān)系可排除C項，D項是一般將來時的被動語態(tài)，正確。berewardedwith...“得到……回報”，可視為固定短語。2．(福建高考)Tomydelight,I________fromhundredsofapplicantstoattendtheopeningceremony.A．waschosen B．wasbeingchosenC．wouldchoose D．hadchosen解析：選A句意：令我高興的是，我從幾百位申請者中被選出來參加開幕式。根據(jù)句意可知這件事發(fā)生在過去，應(yīng)用一般過去時；另外，“我”是被選出，故應(yīng)用被動語態(tài)。結(jié)合前面的分析可知本題應(yīng)用一般過去時的被動語態(tài)，故答案為A項。3．He________asanationalheroforwinningthefirstgoldmedalforhiscountryintheOlympics.A．regarded B．wasregardedC．hasregarded D．hadbeenregarded解析：選B考查一般過去時的被動語態(tài)。beregardedas...意思是“被看作……”。4．You'vefailedtodowhatyou________toandI'mafraidtheteacherwillblameyou.A．willexpect

D．wereexpected解析：選D句中you與expect存在被動關(guān)系，首先排除A、C兩項。根據(jù)語境可知what從句應(yīng)是過去被期盼做的事，故應(yīng)為過去時，正確答案為D。5．Thechurchtowerwhich________willbeopentotouristssoon.Theworkisalmostfinished.A．hasrestored B．hasbeenrestoredC．isrestoring D．isbeingrestored解析：選Drestore意思是“修復(fù)”，而第二句表明修復(fù)工作還未完成，因此是正在修復(fù)中，且要用被動語態(tài)，故選D。6．—Whydoesthelakesmellterrible?—Becauselargequantitiesofwater________.A．havepolluted B．isbeingpollutedC．hasbeenpolluted D．havebeenpolluted解析：選D根據(jù)問句可知，所填動詞表示過去發(fā)生的動作對現(xiàn)在產(chǎn)生的影響，故用現(xiàn)在完成時；主語與謂語動詞之間是被動關(guān)系，所以用被動語態(tài)。主語是largequantitiesofwater，謂語動詞的單復(fù)數(shù)形式由quantity決定，故用復(fù)數(shù)形式。7．Itisrequestedthatsomemeasures________tostop“whitepollution”．A．willbetaken B．a(chǎn)retakenC．shouldtake D．betaken解析：選DItisrequestedthat后的從句要用“(should＋)動詞原形”的虛擬語氣結(jié)構(gòu)，故排除A、B兩項。measures與take之間為被動關(guān)系，故選D項。8．Attheendofthemeeting,itwasannouncedthatanagreement________.A．hasbeenreached B．hadbeenreachedC．hasreached D．hadreached解析：選B主句用了一般過去時，所以從句要用過去的某種時態(tài)，這里表示的動作發(fā)生在主句謂語動詞表示的動作之前，所以用過去完成時。agreement作reach的賓語，所以要用被動語態(tài)。9．—Haveyouhandedinyourschoolworkyet?—Yes,Ihave.Iguessit________now.A．hasgraded B．isgradedC．isbeinggraded D．isgrading解析：選C根據(jù)時間狀語now可判斷出要用現(xiàn)在進(jìn)行時，表示正在發(fā)生的事。再根據(jù)schoolwork與grade的關(guān)系可確定用被動語態(tài)，表示作業(yè)正在被評分。10．—Hi,Torry,canIuseyourcomputerforawhilethisafternoon?—Sorry.________.A．It'srepaired B．IthasbeenrepairedC．It'sbeingrepaired
