before的創(chuàng)新句型。句意：科學家說也許再有5年時間這種藥就可以在人類身上做實驗了。assoonas是最常見的表示＂一……就……＂的從屬連詞，其他連詞還有once（一旦），directly（老式英國英語），immediately（主要用于英國英語），instantly，theinstant(that)，theminute(that)，themoment(that)等，它們通常都可與assoonas換用。Assoonaswegothome,thetelephonerang.我們一到家，就響了。IrecognizedherimmediatelyIsawher.我一看見她就認出她來了。Directlytheteachercameineveryonewasquiet.老師一進來，大家就靜了下來。hardly/barely/scarcely...when和nosooner...than的意思是＂剛……就＂，它們所引導的從句中的謂語動詞通常為過去完成時。Hehadnosooner(nosoonerhadhe)arrivedhomethanhewasaskedtostartonanotherjourney.他剛一到家，就又要他出另一次差?！飄ardly/barely/scarcely和nosooner置于句首時，從句要倒裝。Nosoonerhadthewordsbeenspokenthanherealizedthatheshouldhaveremainedsilent.這些話剛一出口，他就意識到自己應該保持沉默。在含有since引導的時間狀語從句的復合句中，從句的謂語動詞通常為一般過去時，主句的謂語動詞通常為現在完成時。We’venevermetsincewegraduatedfromthecollege. 大學畢業(yè)后我們就再沒見過面。Greatchangeshavetakenplacesinceyouleft.你走了以后，這里發(fā)生了巨大的變化。1.（2017·天津卷·完形填空）Shehadbeentalkingtohermotheraboutthelivesofhomelesspeople42theyfirstsawthehomelessman.A.since B.unless C.although D.as【參考答案】A2.IhaveheardalotofgoodthingsaboutyouIcamebackfromabroad.A.sinceB.until C.before D.When【參考答案】Atill和until同義，作＂直到……時(為止)＂解，till多用于非正式文體，until多用于句首。Donaldwillremainincollegeuntil(till)hefinisheshisPh.Dcourse.唐納德將留在學校直到完成他的博士學位課程。Iwon’tgowithyouuntil(till)Ifinishedmyhomework.等我做完作業(yè)我才和你一起去。注意：notuntil置于句首，主句要倒裝。Notuntil4:00inthemorningcanhefallasleep.直到凌晨4點他才睡著。(Hecan’tfallasleepuntil4:00inthemorning.)Notuntilhereturneddidwehavesupper.直到他回來我們才吃晚飯。(Wedidn’thavesupperuntilhereturned.)(2017·北京卷·單項填空)Ifyoudon’tunderstandsomething,youmayresearch,study,andtalktootherpeople_______youfigureitout.A.because B.though C.until D.since【參考答案】C【答案解析】A.because因為B.though盡管C.until直到D.since自從。句意：如果你無法理解某個東西，你可能會去研究，學習并和他人探討直到你解決為止，根據句意可知選用until“直到”，選C。這類連詞主要有everytime(每次)，eachtime(每次)，(the)nexttime(下次)，anytime(隨時)，(the)lasttime(上次)，thefirsttime(第一次),bythetime(當……的時候)。如：Youcancallmeanytimeyouwantto.你隨時都可以給我打。EachtimeIwentthere,Isawhimworking.我每次去那兒都看見他在工作。EverytimeIseeherI'llthinkofit.每次我看到她，我就想起這事。Nexttimeyouein,pleaseclosethedoor.下次你進來，請關門。Hedidn'ttellmethelasttimeIsawhim.我上次見到他時他沒告訴我。ThefirsttimeIheardaboutthefirmclosingdownwaswhenGeorgetoldme.我最初聽到公司倒閉的消息是喬治告訴我的。Bythetime,hewastakentothehospitalhewasnearlydead.他被送到醫(yī)院時已經幾乎不行了。注意：everytime,eachtime,anytime前不用冠詞，(the)nexttime,(the)lasttime中的冠詞可以省略，而thefirsttime中的冠詞通常不能省略。題組一能力過關=1\*ROMANI．單項填空1.Itwas3inthemorning___________theearthquakehappened.Hundredswerekilled,withalot___________inthecollapse.A.that；buried B.when；buriedC.that；burying D.when；burying2.__________itestotrafficrules,Iofteneacrosssuchcases__________thelocaldriversobviouslyknowthembutwon’tfollowthem.A.If；why B.When；which C.Once；as D.When；where3.Everytime__________theymet,theywouldtalkexcitedlyforseveralhoursabouttheschoolmatesandincidents__________theystillrememberedintheprimaryschool.A.that；whoandwhich B.when；thatC./；that D.when；which4.Manypeoplehaveheardofthe＂braindrain＂.Thisis___________happens__________peoplewithgoodskillsandagoodeducationmovetoothercountryforstudyorwork,oftenatgreatexpensetotheirhomecountries.A.which；when B.what；that C.what；when D.why；when5.—Gladtoseeyou,Kate.—Oh,myGod.It’sbeen20years___________welastsaweachother.A.when B.before C.after D.since6.Hesmiledpolitely____________Maryapologizedforherdrunkenfriends.A.as B.if C.unless D.though7.___________thepoemasecondtime,themeaningwillbeeclearertoyou.A.Havingread B.Whilereading C.Ifreading D.Whenyouread8.Thepolicesetaboutarrestingthesuspect___________theyfoundenoughevidencetoprovehimguilty.A.immediate B.aslongas C.themoment D.asfaras9.Thepolicehadtoemployforce___________thecrowdgotoutofcontrol.A.theinstant B.attheinstant C.inaninstant D.foraninstant10.Ifindividualsareawakened___________theybeginadreamphaseofasleep,theyarelikelytobeeirritableeventhoughtheirtotalamountofsleephasbeensufficient.A.asif B.nowthat C.eachtime D.firsttimewhenII.語法填空Eatingorganicfoodwillnotmakeyouhealthier,accordingtoresearchersatStanfordUniversity,althoughitcouldcutyour
