you.willaregoingtoaregoingto精品課件4、現(xiàn)在進行時ReviewofthePresentContinuousTense教學重、難點：精品課件知識要點：一.現(xiàn)在進行時的定義:

現(xiàn)在進行時是表示現(xiàn)在、說話瞬間或當前一直正在做著的動作.Eg:

1.JennyiswatchingTVnow.

2.Iamwriting.精品課件五.現(xiàn)在進行時的判斷：（1）一般句中用到表示“在現(xiàn)在”的時間狀語，如：now,rightnow,atthemoment或It’s+幾點鐘”句型，常判斷用現(xiàn)在進行時。Eg:Let’sgofast.Mr.Wuiswaitingforusnow.It’ssixo’clock.Thechildrenareplayingbasketball.精品課件(2)句中用到“Listen！”“Look!”“Keepquiet”“Don’tmakenoise!”等提示語時，表明說話間另一個動作正在進行，這時，句子也要用現(xiàn)在進行時。Eg:Keepquiet!Theteachersaretalkingintheoffice.精品課件Shereadisingnow.精品課件Listen!Thebirdissinging.精品課件二.現(xiàn)在進行時的謂語結(jié)構:

現(xiàn)在進行時的謂語結(jié)構為:am/is/are+現(xiàn)在分詞.Am/is/are在現(xiàn)在進行時句子謂語結(jié)構中作助動詞用，無詞義。Am/is/are的選擇運用由句子的主語人稱或數(shù)決定。A:IamwatchingTVathome.B:Dave

iscleaningthefloor.C:Thestudentsareseeingamovie.精品課件2.將現(xiàn)在進行的肯定句變?yōu)榉穸ň鋾r，在be動詞后面加上not.

Eg:

Steveistalkingtohisteacher.Thechildrenareeatingsomeapplesatmyhome.

-----Steveisn’ttalkingtohisteacher.----Thechildrenaren’teatinganyapplesatmyhome.精品課件四.現(xiàn)在進行時的形式轉(zhuǎn)換：1.將一個現(xiàn)在進行時的肯定句變?yōu)橐话阋蓡柧鋾r，將句中的is或are提到句首。Eg:

Steveistalkingtohisteacher

.

Iamsinging.------IsStevetalkingtohisteacher?------Areyousinging?精品課件Talkaboutthepeopleinthepicture.What’shedoing?He’sreading.*

Whataretheydoing?*Theyareplayingbasketball.…精品課件5、過去進行時ReviewofthePastContinuousTense教學重、難點：精品課件過去進行時過去進行時的用法與現(xiàn)在進行時相仿，表示過去某時刻或階段正在進行的動作。結(jié)構：be（過去式）+v.ingEg.Iwasreadinganovelwhenyoucalled.你打電話時我正在看一本小說。精品課件exerciseDanny______(watch)TV,whenyousang.I_________________(playcomputergame)atthistimeyesterday.waswatchingwasplayingcomputergame精品課件6、將來進行時表示將來某時刻正在進行的動作。結(jié)構：will/shall+be+v.ingEg.Wewillbehavingdinnerinaminute.一會兒我們就吃飯。Dannywillbeplayingfootballanhourlater.Danny一會兒將會在打球。精品課件Haveatry試一試:He___________(watch)TVnow.I___________(swim)atthistimeyesterday.She____________(see)thesunriseatthetopofthemountainthistimetomorrow.iswatchingwasswimmingwillbeseeing精品課件Translate翻譯他們一會兒就開會。

Theywillbehavingameeting.我一會兒就洗衣服。

Iwillbewashingclothes.精品課件7、ThePresentPerfectTense現(xiàn)在完成時教學重、難點：精品課件現(xiàn)在完成時現(xiàn)在完成時表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在造成的影響或結(jié)果.通常與表示包括現(xiàn)在在內(nèi)的時間副詞just，already,before,yet,never,ever等狀語連用。精品課件現(xiàn)在完成時結(jié)構助動詞have(has)+V過去分詞注：has用于第三人稱單數(shù)，have用于其他所有人稱。否定句：have/has+not+V過去分詞Eg.①He

hasneverheardofthatbefore.②

Ihaveworkedherefor20years.③Shehasalreadyfinishedthework.④Myaunthaven’tlivedinChinafor3years.精品課件2.現(xiàn)在完成時表示過去已經(jīng)開始，持續(xù)到現(xiàn)在,也許還會持續(xù)下去的動作或狀態(tài)?？梢院捅硎狙永m(xù)的時間狀語連用。如for、since等引導的時間狀語。（注意：句中謂語動詞要用延續(xù)性動詞）一段時間的表達方法有兩種:for:+一段時間forayearfortwoweeksforthreeyears過去的某一時刻,since9o’clocksincelastweek一般過去時態(tài)的時間狀語從句sinceyoucamesinceyougothome.注意:for和since所引導的時間狀語都表示一段時間.Since精品課件注意點（1）：

一些表示短暫性動作的動詞如come,go,

leave,arrive,buy,begin,start,become等

不能與表示一段時間的狀語連用，這些動作

需用表示狀態(tài)的詞連用。Ihavehadthiscoatforoneyear.試比較：1）Ihaveboughtthiscoatforoneyear.×√精品課件轉(zhuǎn)化成延續(xù)性動詞歸納1.直接轉(zhuǎn)化成延續(xù)性動詞

havebeen(to)和havegone(to)的區(qū)別：

★have/hasbeen(to)表示“曾經(jīng)到過某地”，說話時此人不在那里，已經(jīng)回來。側(cè)重指經(jīng)歷?！飄ave/hasgone(to)表示某人“已經(jīng)去某地了”，說話時此人可能在路上或已到那里.試比較：

HehasbeentoBeijing.他曾去過北京。（人已回來，可能在這兒）HehasgonetoBeijing.他已經(jīng)去北京了。（人已走，不在這兒）。精品課件一般過去時與現(xiàn)在完成時之比較

一般過去時表示過去某時發(fā)生的動作或單純敘述過去的事情，強調(diào)動作，和現(xiàn)在不發(fā)生關系。而現(xiàn)在完成時表示過去發(fā)生的某一動作對現(xiàn)在造成的影響或結(jié)果，強調(diào)的是現(xiàn)在的情況。精品課件分析比較

Isawthisfilmyesterday.（只說明動作發(fā)生在過去。）Ihaveseenthisfilm.（強調(diào)對現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。）ShehasreturnedfromParis.（她已從巴黎回來了。）Shereturnedyesterday.（她是昨天回來的。）HehasbeenintheLeagueforthreeyears.(在團內(nèi)的狀態(tài)可延續(xù))HejoinedtheLeaguethreeyearsago.(三年前入團，joined為短暫行為。)精品課件注意：句子中如有一般過去時的時間副詞（如yesterday,lastweek,in1960）時，不能使用現(xiàn)在完成時，要用過去時。例如：（錯）Tomhaswrittenalettertohisparentslastnight.（對）Tomwrotealettertohisparentslastnight.精品課件Exercises
