Unit3TheComputerandtheInformationAge-grammar教案-


一名优秀的教师就要对每一课堂负责,作为高中教师就要早早地准备好适合的教案课件。教案可以让学生能够听懂教师所讲的内容,使高中教师有一个简单易懂的教学思路。那么怎么才能写出优秀的高中教案呢?为了让您在使用时更加简单方便,下面是小编整理的“Unit3TheComputerandtheInformationAge-grammar教案-”,仅供参考,欢迎大家阅读。

Unit3TheComputerandtheInformationAge-grammar教案

动词时态

一、经过前几个单元的学习,到这个单元为止,时态已经学完。按照要求,学生需要掌握下列几个重要时态。

1、一般现在时。

1》概念其基本意义在于表示发生在包括讲话时间在内的动作或状态。

2》理解:本时态主要关注动作的经常性,强调动作表现的事实,或者是真理,而且和现在有关。

〈1〉表示客观真理,科学事实,格言,及其它各种不受时间限制的客观存在状况。

如:Lighttravelsfasterthansound

Actionspeakslouderthanwords

2表示经常性或习惯性的动作。

如;Ourartteacherpractisespaintingtwiceaday.

Tomoftenregularlydropinontheprofessor.

3表示现在的特征或状态。

如:Heisalwaysreadytohelpothers.

Tomseldomrisesatsix.

4有when/while/until/before/assoonas/if/evenif等引导的时间,条件,或让步壮语从句中,常用一般现在时。

如:whenwegetthere,wellcallyou.

Noonecangothroughwiththetaskontimeifitrains.

IllnotattendherbirthdaypartyevenifIaminvited.

5在新闻标题,小说,戏剧,电影,图片等说明中,也经常用一般现在时。

如:TheDelegationofChinagetsawarmwelcomeinRussia.

Thestoryisaboutafamily---.Thehusbandcomeshomefromhisofficeandtellsthewifethathehasinvitedafriendtodinner.

3》标志:often/always/usually/seldom./never..对上述壮语提问时,常用howoften...?肯定句中,动词用第三人称单数形式。

如:

---Howoftendoeshevisittheoldman?

—---Never.

2.一般过去时

1》概念本时态主要是表示过去的时间内发生的动词作或者是状态。

2》理解强调过去动作的一次性和习惯性。

1表示过去特定时间的一次完成的动作。

如:Theoldprofessorsteppedintotheclassroom,openedthebook,andbegantoread.

WewenttoBeijingandvisitedHeavenTemple.

2用它表示习惯性动作,往往用一定的时间状语或表示频度的状语。

如:wewenttoschooltogetherwhenwewereboysandsowesaweachothereveryday.

Thereusedtoatempleinthevillage.

在日常会话中,我们也用一般过去时表示现在的时间。这种用法在讲话的口气上表现出婉转,客气的意味。

如:---Didyouwantme?

----Yes,Ihopedyoucouldgivemeahandwiththepainting.

3》警示:除了表示明显的过去时间状语外,还有usedto/would等暗示性词语。

如:whenIwasinLondon,often,Iwouldhaveacupofcoffeeafterwork.

注意:上句中的would不能用usedto代替。这两个词虽然都表示"过去常常",但would常和时间连用,如often,everyday等,而usedto不可以。

3。一般将来时

1》概念表示将来要发生的动作。

2》理解对未来事情的预见性,或者说明意图,打算。

1用will或shall+动词的形式表示对未来事情的预见性,又称为预见性将来时。

如:Tomorrowwillbefine.

Youwillfeelbetteraftertakingthemedicine.

2用begoingtodo表示将来。

用这种形式表示将来主要是说明现在的意图,打算,即表明眼前最近要去做的事情。又称之为近期将来。如:Imgoingtoposttwolettersafterclass./Sheisgoingtohaveauniversitydegree.

如果这种结构用物做主语,也是一种预见,可以用will代替。

如:Itisgoingtorain

Watchout!Thepillofboxesisgoingtofall.

3用be+going表示将来

一般说来,用现在进行时表示将来所用的时间大都是动作动词,不适用于状态动词。用这种结构表示按计划要去做的事或发生的事情。

如:wereinvitingseveralpeopletoaparty.

TheforeignministryiscomingtotheUNthisweek.

Theplaneistakingoffat5:30

一般来说,bedoing/begoingtodo两种结构均可以表示将来,但有些区别。

比较:IamtakingMaryoutfordinnertonight.

IamgoingtotakeMaryoutfordinnertonight.

第一句表示计划已定不能改变,第二句表示打算未定只是一种想法而已。

4用be+todo表示将来时间

这种结构也可以表示按计划,随安排将要去做的事情或将要发生的动作。

如;Theworkersaretoproduce5000carsnextyear.

ThePrimeMinisteristospeakontelevisiontonight.

ThelineistobeopentotrafficonOctober1.

这种结构表示的将要发生的动作一般来说受人们意志控制或支配的。可以互换,但语意上有区别。如:

Wearegoingtoplaybasketballthisafternoon.表示目前的意图

Wearetoplaybasketballthisafternoon.表示计划,安排或受人的支配.

我们可以说:Itsgoingtorain/Theyoungmanisgoingtobefat.

但不能说:Itistorain/Theyoungmanistobefat.

5用一般现在时表示将来。

如:NextChristmasfallsonaTuesday

Thetrainleavesat7:30thisevening.

Theplanetakesoffat6:40.

3》警示 除了上述那些之外,也用beaboutto/beonthepointof/beonthemiddleof/表将来。

如:Themeetingisabouttobegin.

Weareonthepointofgoingout...

但值得注意的是这种形式不和将来的时间用在一起。我们不可以说theyareabouttoleavethisafternoon.

4。进行时

1》概念 表示某时某刻某阶段正在进行的动作。

2》理解 进行的动作包括现在,过去和将来。

一现在进行时

本结构是am/is/are+doing构成的形式。这种时态表示的动作主要与现在时间有关系。有如下的用法。

1表示此刻正在进行或发生的动作 常伴有时间状语。如:now/atpresent/atthemoment

Atpresent,thestaffareholdingameeting.

Wherearetheyhavingthebasketballmatch?

2表示现阶段正在进行的动作。

 Iusuallygetupatseven,butImgettingupatsixeverydaythisweektopreparemylessons.

Selectingamobilephoneisdifficult.Thetechnologyischanging.

3如果和表示频度的时间状语连用,不表示动作的进行,而表示动作的重复性,在语意上带有感情色彩。如:

 Youarecontinuallyfindingfaultwithme.表不满》

Heisalwaysthinkingofhowhecoulddoforthepeople《表赞扬〉

Theoldmanisconstantlycomplainingofhiswatchbeingslow.〈发牢骚〉

〈二〉过去进行时。

本结构是was/were+doing构成的形式。它表示的状态或动作主要和过去的时间有联系,所以往往和表示过去的时间连用。

 〈1〉表示过去某时刻正在进行的动作。如:

Whatwereyoudoingattenlastnight?

WhenIgotupthismorning,itwasrainingoutside.

2 表示过去某阶段中正在进行的动作。如:

 Atthattime,hewasworkinginaPLAunit.

Inthoseyearshewashavingahappylife.

3在叙述故事的背景时,为了使故事的语言更加生动,让读者有身临其境的效果,多用进行时。如:Onemorningthethreesistersweretogetherinthedrawingroom.Marywassewing,Alicewasplayingthepiano,andJanewasdoingnothing,thensuddenlythedooropened...

正如现在进行时一样,过去进行时与表示频度的时间状语连用,也能表示某种情感色彩。

3》警示 进行时还常用在语境中,表示语气的委婉。如:

---Whatareyougoingtodo?

---Imhopingtoinviteyoutodinner.

5.完成时。

1》概念 本时态是表示某动作或某过程在一定时间内处于完成的状态。

2》理解 完成时包括现在完成时和过去完成时态。构成分别为havehasdone/haddone.

一现在完成时。动作在过去发生,持续到现在已经完成,或者是继续持续下去。

 1已经完成的用法。其表明某动作或过程发生在说话前某个不明确的过去时刻,到目前一完成,并对目前造成影响。如:Hehasnotbeentoshanghai/Haveyoufinishedreadingthestory?

本用法常和不确定时间状语连用。如:already/yet/before/recently/lately/just...等

Ihaveseenhimbefore

wehaventbeentherelately

也可以和表示频度的时间状语用在一起。如:ever/never/once---等。

IhaveneverbeentoHongkong.

HaveyouevervisitedtheGreatWall?

2未完成的用法。本用法表示某动作或状态开始于过去某个时刻一直延续到现在,而且还要继续下去,在某种情况下也可能刚刚结束。常和since/for/时间状语连用。如:

Hehasbeeninthearmyfor3years.

Hehaslivedinthebuildingsincehecamehere.

3》警示:如果不过since引导的从句中的动词是延续性的,一般认为,语意上也表明动作或状态的结束。如:

Ihaventheardfromhimsincehelivedthere.

从他离开那儿以来,我一直未收到他的消息。

HehaswrittentomefrequentlysinceIwasill.

从我病愈以来,他常给我写信。

如果since引导的从句中的谓语动词用了现在完成时,那么表示的动作或状态就不表示完结。如:

Ihaventheardfromhimsincehehaslivedthere.

从我住在那里以来,我一直未收到他的来信。

HehaswrittentomefrequentlysinceIhavebeenill.

从我生病以来,他常给我写信。

二过去完成时。本时态表示的是动作在过去的过去发生。它也分为“已完成用法”和“未完成用法”。

1已完成用法。表示,当一个动作发生或结束时,在它之前的另一动作已经完成。这种用法既用于动作动词,也用于状态动词。如:

Whenwearrivedthecinema,theticketshavebeensoldout.

Tomflewhome,buthisfatherhadalreadydied.

Iwastoldthattheoldmanhadbeenawayforaweek.

2未完成用法。表明某个动作或状态在过去某个时刻之前一直延续到过去这个时间,而且还可能继续下去。它也使用于动作和状态动词。而且常和By+过去时间或从句 连用。如:

By12,hehadstudiedfor4hours.

Bywegotthere,theyhadendedthemeeting.

Wehadworkedtogetherforalongtimebeforewecametothiscollege.

3警示:在by+过去时间或从句的结构中,如果主句动词是动作动词,用过去完成时,如果是状态动词,用一般过去时。比较:

 Bytheendoflastyear,hewas12.

Bytheendoflastyear,hehadlearned300Englishwords.

另外,在---hardly---when/---nosooner---than---的句中,主句用过去完成时,从句用一般过去时。而且,如果hardly./nosooner提前,主句需要部分倒装。如: 

IhadhardlyrecoganizedhimwhenIsawhim.

HardlyhadIrecoganizedhimwhenIsawhim.
