Unit1Ⅰ能夠表示動作將要發(fā)生的時(shí)態(tài)⑴一般現(xiàn)在時(shí)。1）它表示一個(gè)按規(guī)定、計(jì)劃或安排要發(fā)生的情況。常常要加一個(gè)表示未來時(shí)間的狀語。Whendoesthewinterholidaybegin？WhattimedoesthetrainleaveforShanghai？Isthereafilmtonight？TomorrowisSaturday．Schoolbeginsthedayaftertomorrow．但這種用法只限于少數(shù)動詞，如：begin，come，go，leave，sail，start，arrive，return，end，stop，open，close，take，be等。2)在時(shí)間或條件狀語從句中，一般現(xiàn)在時(shí)也可用來表示將來的動作。Youwillpasstheexamsifyouworkhard．⑵現(xiàn)在進(jìn)行時(shí)注意：時(shí)間必須指出或在前文中已經(jīng)指出，不然就可能造成現(xiàn)在時(shí)與將來時(shí)之間的混淆。1）現(xiàn)在進(jìn)行時(shí)可以表示對最近的將來的確定的安排：I’mtakinganexaminOctober．BobandBillaremeetingtonight．這句意指鮑勃和比爾已作了會面的安排。如僅僅表示意圖，則要用begoingto形式。2）但是，表示從一個(gè)地方運(yùn)動到另一個(gè)地方的動詞如arrive，come，drive，fly，go，leave，start，travel，表示位置的動詞如stay和動詞do與have（表示吃、喝），它們的現(xiàn)在進(jìn)行時(shí)形式的用法就比較廣泛，可以表示沒有具體安排好細(xì)節(jié)的決定或計(jì)劃。⑶begoingtodo結(jié)構(gòu)1)begoingto表示主語進(jìn)行某一將來行動的打算。這種打算常經(jīng)過預(yù)先考慮并含有已做好某些準(zhǔn)備的意思，因此通常認(rèn)為用begoingto表達(dá)的行動很可能會見諸實(shí)施，雖然不具現(xiàn)在進(jìn)行時(shí)所表示的對將來的確定的安排的概念。請注意以下幾點(diǎn)：①如前所述，begoingto結(jié)構(gòu)帶時(shí)間狀語可以用來表示最近將來的行動。在這種情況下，它可用來代替現(xiàn)在進(jìn)行時(shí)。可以說：I’mmeetingTomatthestationatsix．我6點(diǎn)鐘到車站接湯姆。I’mgoingtomeetTomatthestationatsix．我打算6點(diǎn)鐘到車站接湯姆。注意：I’mmeetingTom含有和湯姆約好的意思，而I’mgoingtomeetTom則沒有，我去后湯姆可能會感到意外。②想強(qiáng)調(diào)主語的意圖時(shí)，begoingto結(jié)構(gòu)可以與時(shí)間從句連用。Heisgoingtobeadentistwhenhegrowsup．Whatareyougoingtodowhenyouhavetime？然而，通常是一般將來時(shí)（shall／will）和時(shí)間從句連用。③begoingto結(jié)構(gòu)可以不和時(shí)間連用：I’mgoingtobuyagiftformymother．Heisgoingtolendmehisbicycle．這里通常指的是即將進(jìn)行或在最近將來進(jìn)行的動作。④如上面②中所看到的，begoingto結(jié)構(gòu)可以與動詞be連用。有時(shí)也跟通常不能用進(jìn)行時(shí)的動詞連用：Iamgoingtothinkaboutit．I’msureI’mgoingtolikeit．⑤注意：一般不常把動詞go和come用于begoingto結(jié)構(gòu)中，而常用現(xiàn)在進(jìn)行時(shí)來代替begoingto結(jié)構(gòu)，即通常不用I’mgoingtogo而用Iamgoing，不用Iamgoingtocome而用Iamcoming。⑵begoingto結(jié)構(gòu)可以表示通過某種跡象可以推測出即將發(fā)生的動作。Lookatthoseclouds！It’sgoingtorain．Listentothewind．We’regoingtohaveacoldday．begoingto結(jié)構(gòu)在動詞besure／afraid，believe，think之后都可以這樣用：Howpale(蒼白)thatgirlis！Iamsure／Ibelieve／Ithinksheisgoingtofaint(昏倒)．⑷一般將來時(shí)的用法1)表示說話人對于將來的看法、假定和推測的句子中常由動詞beafraid，be／feelsure，believe,expect，hope，know，suppose，think，wonder等來引導(dǎo)或與副詞perhaps，possibly，probably等連用，但也可以不用這些副詞：①（I’msure）he’llcomeback．②（Isuppose）they’llsellthehouse．③（Perhaps）we’llfindhimatthehotel．④They’ll（probably）waitforus．2)一般將來時(shí)可以與時(shí)間連用，也可以不連用。這里有時(shí)也可以用begoingto，但后一種用法使動作的可能性顯得更大些，而且如果沒有時(shí)間時(shí)動作可能會發(fā)生得更快些。He’llbuildahouse（他要蓋房子）僅意指這是我的看法而不含有什么時(shí)候開始蓋房子的概念。但He’sgoingtobuildahouse（他打算蓋房子）則意指他已經(jīng)做出決定，很可能不久將著手蓋。2)一般將來時(shí)用來表示通常認(rèn)為將要有的習(xí)慣性動作：①Springwillcomeagain．②Birdswillbuildnests．③Peoplewillmakeplans．④Othermenwillclimbthesestairsandsitatmydesk．3)一般將來時(shí)常用在帶條件從句、時(shí)間從句的句子中，有時(shí)用在帶目的從句的句子中：IfIdropthisglassitwillbreak．如果我把這個(gè)杯子掉到地上，它就會摔碎。Whenitgetswarmerthesnowwillstarttomelt．天氣變暖時(shí)，雪開始融化。注意：在if從句或時(shí)間從句中，即使句子是指將來，也不用將來時(shí)：不能說：I'lltelephoneyouifIwillcome.而要說：I'lltelephoneyouifIcome.不能說：IamgoingtobuyacomputerwhenIwillarriveinBeijing.而要說：IamgoingtobuyacomputerwhenIarriveinBeijing.⑸比較begoingto與willbegoingto與will兩者都可表示將要發(fā)生的事、將要去做某事，但用法還是不同的。⑴begoingto表示近期、眼下就要發(fā)生的事情，will表示的將來時(shí)間則較遠(yuǎn)一些，如：Heisgoingtowritealettertonight.Hewillwriteabookoneday.⑵begoingto表示根據(jù)主觀判斷將來肯定發(fā)生的事情，will表示客觀上將來勢必發(fā)生的事情。Heisseriouslyill.Heisgoingtodie.Hewillbetwentyyearsold.⑶begoingto含有“計(jì)劃，準(zhǔn)備”的意思，而will則沒有這個(gè)意思，如：Sheisgoingtolendusherbook.Hewillbehereinhalfanhour.⑷在有條件從句的主句中，一般不用begoingto,而多用will,如：Hewillhelpyouifyouareintrouble.注意：對于上述時(shí)態(tài)的用法，我們只要知道能夠表示動作即將發(fā)生的時(shí)態(tài)有“一般現(xiàn)在時(shí)”、“現(xiàn)在進(jìn)行時(shí)”、“begoingtodo結(jié)構(gòu)”、“一般將來時(shí)”即可，而它們的具體用法了解即可而不需掌握。但對于那些基礎(chǔ)好的同學(xué)，可以多讀讀。II句型⑴一般將來時(shí)的句子結(jié)構(gòu)肯定句：Peoplewillhaverobotsinthefuture.Therewillbemoretreesandlesspollution.否定句：Peoplewon'tusemoney.Therewon'tbeanyschoolsinthefuture.一般疑問句：-Willpeopleusemoneyin100years?-Yes,theywill.No,theywon't.-Willtherebeanyrobotsinourhomes?-Yes,therewill.No,therewon't.特殊疑問句：WhatwillSallybeinfiveyears?⑵原因狀語從句(because...)I'llliveinShanghai,becauseIwenttoShanghailastyearandfellinlovewithit.⑶定語從句Therearemanyfamouspredictionsthatnevercametrue.⑷賓語從句Ithinktherewillbemorepollution.Hethoughtthatcomputerswouldneverbeusedbymostpeople.Theheadpredictedthatnoonewouldwanttoseeactorstalk.Ⅲ詞匯（以頁碼先后順序?yàn)闇?zhǔn)）P21free⑴adj.notbusy,notworking,etc.不忙的，空閑的Willyoubefreethisafternoon?Ishallnotbefreeuntilfiveo'clock.Hehadnofreetime.⑵adj.thatcostsnothing.免費(fèi)的，免稅的Theparksinthecityareusuallyfreeexceptonholidays.Youmayhavefreeuseofmyhousethissummer.2oncomuters,onpaperKidswon'tgotoschool.They'llstudyathomeoncomputers.Bookswillbeonlyoncomputers,notonpaper.-MayIuseyourcomputer?-Sorry,butIhavetoworkonitnow.3learn與study的比較⑴learn一般側(cè)重學(xué)習(xí)成果，因此，可譯為"學(xué)會"、"學(xué)到"；而study則側(cè)重學(xué)習(xí)過程。IlearnttodriveacarwhenIwassixteenyearsold.Whatsubjectsdoyouusuallystudyatyourschool?⑵learn一般用于"從不知到知、不會到會"的初級學(xué)習(xí)階段或有模仿性的操作技藝等；st
