四、be going to+动词原形与willshall+动词原形”构造的转换“be going to+动词原形”、表达打算、计划要做的事;未来时“willshall+动词原形”构造在书面语中,当主语为第一人称时,常用助动词shall在口语中,所有人称都可以用willo请看rd ratheryou cametomorrow.We are goingtovisit theGreat Wall4)wish,wonder,think,hope等用过去时,作试探性的问询、祈求、提议等I thoughtyou mighthave some.我认为你想要某些比较一般过去时表达的动作或状态都已成为过去,现已不复存在Christine wasan invalid all her life.(含义她已不在人间)Christine hasbeen aninvalidallherlife.(含义她目前还活着)Mrs.Darby lived in Kentucky for seven years.(含义达比太太已不再住在肯塔基州)Mrs.Darby haslivedinKentuckyforsevenyears.(含义目前还住在肯塔基州,有也许指刚拜别)注意用过去时表达目前,表达委婉语气1)动词want,hope,wonder,think,intend等Did youwant anythingelseI wonderedif youcould help me.2)情态动词could,would.Could youlend meyour bike
3.used to/be used toused to+do过去常常表达过去习惯性的动作或状态,但如今已不存在Mother usednot tobe soforgetful.Scarf used to takeawalk.(过去常常散步)be usedto+doing对……已感到习惯,或“习惯于”,to是介词,后需加名词或动名词He isusedtoa vegetariandiet.Scarf isusedtotaking awalk.(目前习惯于散步)经典例题——Your phonenumber againI quitecatch it.--Its
69568442.,A.didnt B.couldnt C.don tD.cant答案A.本句虽没有明确的时间状语,但从语意上看出,在听的时候没有听懂这个动作发生在过去,因此应用过去时
4.一般未来时1)shall用于第一人称,常被will所替代will在陈说句中用于各人称,在争求意见时常用于第二人称Which paragraphshall Iread first.Will yoube athome atseven thisevening2)be goingto+不定式,表达未来a.主语的意图,即将做某事What areyou goingto dotomorrowb.计划,安排要发生的事The playis goingtobeproduced nextmonthoc.有迹象要发生的事Look atthe darkclouds,there isgoingtobe astorm.3)be+不定式表未来,按计划或正式安排将发生的事We areto discussthe reportnext Saturday.4)be about to+不定式,意为立即做某事He isabouttoleave forBeijing.注意be aboutto不能与tomorrow,next week等表达明确未来时的时间状语连用

6.be to和be goingtobe to表达客观安排或受人指示而做某事be goingto表达主观的打算或计划Iamto play football tomorrowafternoon.(客观安排)Im goingto playfootball tomorrowafternoon.(主观安排)
7.一般目前时表未来1)下歹U动词come,go,airive/eave,start,begin,return的——般目前时表未来这重要用来表达在时间上已确定或安排好的事情The trainleaves atsix tomorrowmorning.When doesthe busstar Itstars inten minutes.2)倒装句,表达动作正在进行,如Here comesthe bus.=The busis coming.There goesthe bell.=The bellis ringing.3)在时间或条件句中When Billcomes(不是will come),ask him to waitfor me.Ill writeto youas soonas Iarrive there.4在动词hope,take carethat,make surethat等后I hopethey havea nicetime nextweek.Make surethat thewindows areclosed beforeyou leavethe room.
11.用于目前完毕时的句型1It isthe first/second time.…that…构造中的从句部分,用目前完毕时It isthe first time thatI havevisited thecity.It was the thirdtimethatthe boyhad beenlate.2This isthe...that…构造,that从句要用目前完毕时,This isthe bestfilm thatTveever seen.这是我看过的最佳的电影This isthe first timethatTve heardhim sing.这是我第一次听他唱歌经典例题1—Do youknow our town atall-No,this isthe firsttime I here.A.was B.have beenC.came D.am coming答案B.This isthe firsttime背面所加从句应为目前完毕时,故选答2—Have youbeentoourtownbefore-No,its the firsttimeI here.A.even,come B.even,have comeC.ever,come D.ever,have come答案D.ever意为曾经或无论何时,反意词为never,此两词常用于完毕时This isthe largestfish Ihaveever seen.It is/wasthefirsttime+that-clause的句型中,从句要用完毕时注意非延续性动词的否认形式可以与表达延续时间的状语连用即动作不发生的状态是可以持续的错I havereceived his letter fora month.对I haven5t receivedhisletterfor almosta month.12比较since和forSince用来阐明动作起始时间,for用来阐明动作延续时间长度I havelived here for more than twenty years.I havelived heresince I was born..My aunthas workedin aclinic since
1949.Some newoilfields have been openedup since
1976.I haveknown XiaoLi sinceshe wasa littlegirl.My brotherhasbeenintheYouth Leaguefor twoyears.I havenot heardfrom myuncle fora longtime.注意并非有for作为时间状语的句子都用目前完毕时I worked hereformorethantwentyyears.(我目前已不在这里工作)Ihaveworkedherefor manyyears.(目前我仍在这里工作)小窍门当目前完毕时+一段时间,这一构造中,我们用下面的公式转化,很轻易就能排除非延续动词在完毕时中的误使1)(对)Tomhas studiedRussian forthree years.=Tom beganto studyRussian threeyears ago,and isstill studyingit now.2)(错)Harryhas gotmarried forsix years.=Harry beganto getmarried s汉years ago,and isstill gettingmarried now.显然,第二句不对,它应改为Harry gotmarried sixyearsago.或Harry hasbeen marriedforsix years.
13.since的四种使用方法1)since+过去一种时间点(如详细的年、月、日期、钟点、1980,last month,half past)sixoI have been heresince
