第一章英语动词时态
(Tenses)
英语时态是英语语法中的第一道难关,攻下此难关是作文、阅读、口语之关键。
汉语用不同词表达相应时态,而英语用同一词的不同变化形式表达时态。
一、一般现在时:
1.构成:
使用动词原形,第三人称单数须有变化。
(1)直接加“s”,works,takes
(2)以辅音加“y”结尾,变“y”为“i”,再加“es”
carry→carries
(3)以“o,s,x,ch,sh”结尾的动词加“es”
goesdresseswatchesbrushes
2.功能:
(1)表现在的事实、状态或动作:
eg:
►.Birdsfly.
►.Shelovesmusic.
►.Mary'sparentsgetupveryearly.
(2)表习惯性动作或职业,常与often,sometimes,usually,always,everyweek,seldom,occasionally,frequently等时间副词连用。
eg:
►.Ialwaystakeawalkaftersupper.
►.Shewritestomeveryoften.
►.Tomandhisgirlfriendgoouttotakeapicnicoccasionally.
(3)表客观真理,格言警句或事实:
►.Theearthmovesroundthesun.
►.Thesunrisesintheeastandsetsinthewest.
►.Twoandtwomakesfour.
►.Nomanbuterrs.人非圣贤,熟能无过。
(4)表将来:
A.在由when,after,before,as,assoonas,although,because,if,evenif,incase,till,until,unless,
solongas,where,whatever,wherever等引导的状语从句中用一般现在时表将来发生的动作。
(黄金重点,所有考试都不放过它!
)
例如:
►.I'lltellherwhenshecomestomorrow.
►.Evenifitrainsthisafternoon,I'llmeetyou.
►.Whateverhappens,youshouldkeepcool-headed.(不错的句型,背下!
!
)
►.I'llberightherewaitingforyouwhereveryougo.(很感人的句型!
)
B.按时间表示将要发生的动作或事件,用一般现在时表达将来时概念。
►.Theplaybeginsat6:
30thisevening.
►.Whendoestheplanetakeoff?
►.Heleavesforthatcitynextweek.
►.Accordingtothetimetable,theexpresstraintoShanghaistartsatnineinthemorning.(按照时刻表,开往上海的特快列车早上7点出发。
)

二.现在进行时:
is/am/are+现在分词
1.表示现在正在进行的动作。
如
►.Thekettleisboiling.ShallImaketea?
►.Don'tyouthinkyoueattoomuch?
You'reputtingonweight(体重增加)。
►.Theworkersarebuildinganewbridgeacrosstheriver.
2.表现阶段正进行的动作。
►.Heistakingphysicsthissemester(本学期)。
►.Wearepreparingforourfinalexaminationthisweek.
3.go,come,leave,arrive,land,meet,die,start,return,join,etc.用于进行时态时表示即将开始的动作。
►.Look!
Thebusiscoming.看!
车来了!
►.Theoldmanisseriouslyill,andheisdying.
►.AliceisleavingforBeijingwithhermother.
4.与always,forever,continually,constantly等副词连用,表示说话人带有感情色彩:
赞赏或厌恶。
►.Heisalwaysthinkingofothers.(他总是想着别人。
)
►.Theboyiscontinuallymakingnoises.(这男孩不断地发出吵闹声。
)
►.Theteacherisconstantly(always)criticizingherforbeinglate.(老师一直在批评她迟到。
)
5.下面表示状态、感觉、情绪、精神活动的动词不可用于进行时。
(此条戒律请背10遍!
!
!
)
believe(相信),doubt(怀疑),see(看见),hear(听见),know(知道),understand(理解),belong(属于),think(认为),consider(认为),feel(觉得),look(看起来),seem(看上去),show(显示),mind(介意),have(有),sound(听起来),taste(尝起来),require(要求),possess(拥有),care(关心),like(喜欢),hate(讨厌),love(喜爱),detest(憎恨),desire(意欲)
【简单记忆】:
●永远不要说I'mbelieving...或Heisseeingahouse.再简单一点说,这些动词后面不要随意加-ing.
●可怕的是:
我们在写作及口语中常犯此类大错!
●注意:
haveaparty/thinkabout可以用进行时,因为这里have意为“举行”;think意为“考虑”。

have/has+过去分词

常与yet,just,before,recently,lately(最近),ever,never等表时间的副词搭配使用。
●Hehasn'tseenherlately.
●Ihaven'tfinishedthebookyet.
2.表示一个从过去某个时间开始,延续到现在并可能持续下去的动作,常与表示一段时间的时间状语连用。
如:

die,arrive(到达),join(加入),leave(离开),go,refuse(拒绝),fail(失败),finish,buy,marry,divorce(离婚),awake(醒),buy,borrow,lend...(背三遍!
)
II.这类动词并非不能用现在完成时,而是不能接常由for引导的时间状语。
III.但若是用在否定句中,非延续动词的现在完成时可以与表示一段时间的状语连用。
●Shehasgoneawayforamonth.(误
●Shehasbeenawayforamonth(正)
●Themanhasdiedfortwoyears.(误)

追求)
2.表某种感情色彩。
►.I'vebeenwantingtoseeyouforsomanyyears.
