15、e to the telephone.他现在在工作,所以不能来接电话。现在进行着的动作皆被视为未完成的动作:He s talking to his girlfriend on the phone.他正在和他的女朋友通电话。可用still 一词强调动作的持续性Hes still talking to his girlfriend on the phone.他仍在和他的女朋友通话。2 暂时情况 现在进行时可用来表示不会长期发生的动作或情况,或被认为在短期内正在进行的动作或存在的状况。Whats your daughter doing these days ?

17、示当前的动向:People are becoming less tolerant of smoking these days .如今人们对吸烟较为难以忍受了。3 事先计划好的动作:指将来现在进行时可表示为将来安排好的活动和事件;除在上下文中意思清楚者外,通常需要一个表示时间的状语:Were spending next winter in Australia.我们将要在澳大利亚度过明年冬天。用arrive ,come, go ,leave 等动词的现在进行时描写行程安排,也通常有“将到达”和“将离去”的意思。Hes arriving tomorrow morning on the 13.27 t

19、 him .我常听说关于他的一些怪事。当现在进行时表示某事发生的次数过多时,则有时含有抱怨的意思:Our burglar alarm is forever going off for no reason.我们的防盗警报器不知怎么常常失灵。一般现在时和现在进行时的区别:1 一般现在时和现在进行时常用来解说当时发生的事件,特别是在电台和电视广播中。在这种情况下,一般现在时常用来表示说话时刚完成的快速动作,现在进行时则常用来描述持续时间较长的动作:MacFee passes to Franklyn, Franklyn makes a quick pass to Booth .

22、将来某个时间要发生的动作或存在的状态,常与表示将来的时间连用。如:tomorrow, next week等。但在表示准备、计划、打算做某事时,常用be going to加动词原形的结构。 如:Were going to see Uncle Wang tomorrow.1) shall用于第一人称,常被will 所代替。will 在陈述句中用于各人称,在争求意见时常用于第二人称。Which paragraph shall I read first?Will you be at home at seven this evening?2) be going to +不定式,表示将来。a. 主语的意图

23、,即将做某事。What are you going to do tomorrow?b. 计划,安排要发生的事。The play is going to be produced next month。c. 有迹象要发生的事Look at the dark clouds, there is going to be a storm.3) be +不定式表将来,按计划或正式安排将发生的事。 We are to discuss the report next Saturday.4) be about to +不定式,意为马上做某事。He is about to leave for Beijing.注意:

24、be about to 不能与tomorrow, next week 等表示明确将来时的时间状语连用。一般过去时一般过去时由动词的过去式表示,表示过去发生的动作或状态。过去式分为规则变化和不规则变化。 一般过去时的构成:a. be动词过去式的句式。否定句是在was/were后面加not,was not (wasnt)/were not (werent)。一般疑问句是把was / were提前并放到句首,要求首字母要大写。b.实义动词过去式的句式。肯定式:主语+动词过去式+其它。如:They had a good time yesterday.否定式:主语+did not(didnt)+动词原形

26、ay.昨天他突然生病了。The engine stopped because the fuel was used up.发动机因燃料用光而停机了。b)表示过去经常发生的动作或存在的状态。I wrote home once a week at college.我上大学时每周给家里写一封信。He was already in the habit of reading widely in his boyhood.他童年时就养成了广泛阅读的习惯。注:表示过去的习惯性动作,除了用过去时外,还可以用used to或would来表示。She used to study late into the night

27、 when she was in Senior Three.她上高三时经常学习到深夜。He would sit for hours doing nothing.过去他常常一坐几个钟头什么事也不做。 c)表示过去连续发生的一系列动作。She entered the room, picked up a magazine and looked through it carefully.她走进房间,拿起一本杂志,认真地翻阅了起来。The students go up early in the morning, did morning exercises and then read English al

28、oud in the open air.学生们很早起床,做早操,然后在室外朗读英语。d)在时间、条件状语从句中表示过去将要发生的动作。We would not leave until the teacher came back.老师回来我们才会离开。She told me she would not go if it rained the next day.她告诉我如果第二天下雨的话,她就不去了。一般过去时的特殊用法a)在虚拟语气中表示现在或将来时间的动作或状态。Its time we went.该是我们走的时候了。I wish I were twenty years younger.但愿我年

29、轻20岁。I would rather you didnt do anything for the time being.我宁愿你暂时先不要采取什么措施。b)在口语中,一般过去时往往显示委婉客气。I wondered if you could give me a hand.我想请你帮个忙。Might I come and see you tonight?我想今晚来看你,好吗? 一般过去时的时间状语表示一般过去时的时间状语有:a moment ago(刚才),yesterday morning,last night/ week,the day before yesterday(前天),just

30、now(刚才)等。动词一般过去式的构成a.规则动词过去式的变化可速记为直、去、双、改四字诀。一般情况下在动词原形后直接加-ed。如:wanted,played。以不发音的字母e结尾的动词,去掉e再加-ed。如:hoped,lived。重读闭音节单词需双写最后一个辅音字母再加-ed。如:stopped。以辅音字母+y结尾的动词变y为i,再加-ed。如:studied,worried。规则动词过去式的读音也有规律可循。请记住:清后t,元浊d,t d之后读Id。清辅音p k f s F 等后,ed要读t。如:worked,finished。元音或浊辅音b g v z m等后,ed要读d。如:live

31、d,called。t或d后,ed读Id。如:started,needed。b.不规则动词变化,要逐一熟记。be动词过去式有两种形式,主语是第一、三人称单数形式使用was,其他人称用were。注意事项:A) 注意时间状语的搭配。一般过去时的时间状语应该是表示过去某个时间的词或词组,如:yesterday, last month, in 1999, two days ago等,绝对不可与recently, in the past 10 years, this month等连用,因为这样的时间状语都与现在有关系,应该用现在完成时或一般现在时。B) used to do的否定形式和疑问形式很特别:你怎

32、么写都正确。以否定形式为例:used not to do, didnt used to do, didnt use to do都对。Used to do经常与 be used to doing sth/ sth结构进行对比。前者表示过去常常或过去曾经,要求加动词原形;后者表示习惯于,要求加名词或动名词。现在完成时表示到说话时刻为止已经做或尚未做过的动作。常用already, yet, so far, by now, since two days ago, for a few days 等词语作状语。 注:give, see, come, arrive, leave(离开),begin, sta

33、rt, finish, join, become, borrow, lend, die, end 等点时间动词可以用于完成时,但在肯定句中不能与表示一段时的 since和for 短语连用,因为点时间动词不能延续,而在否定句中可以与表示一段时间的for短语连用,因为否定的点时间动词可以看作是一种可延续的状态。Mike has come for a year.( )Mike has been here for a year( )Mike hasnt come for a year.()过去完成时表示截止到过去某一时刻或在过去的动作之前(过去的过去)已经做或尚未做的动作。By (=up to )la

34、st weekend we hadnt got any information.When he appeared, we had waited for 30 minutes.现在完成时考点考点一:考查基本概念例 Both his parents look sad . Maybe they _whats happened to him .(呼和浩特). knew . have known . must know .will know简析:现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。这种考查难度较大,往往无时间状语,需要从

35、上下文分析、推理才行。故上两侧根据上下文分析、推理,正确答案是。考点二:考查时间状语例1. He has _ been to Shanghai , has he ?. already .never .ever . still例2. Have you met Mr Li _?. just . ago .before . a moment ago例3. The famous writer _ one new book in the past two year . is writing .was writing .wrote .has written例4.Our country _ a lot so

36、 far .Yes . I hope it will be even _ . has changed ; well . changed ; good. has changed ; better . changed ; better例5. Zhao Lan _already _in this school for two years . was ; studying . will ; study. has ; studied . are ; studying例6. We _ Xiao Li since she was a little girl . know . had known . have

37、 known . knew例7. Harry Potter is a very nice film .I_ it twice . will see . have seen . saw .see简析:现在完成时的时间状语常有如下四类:现在完成时常与already(已经),just(刚刚,正好),ever(曾经),never(从来,也不;从不),before(以前),yet(仍然)等连用。故例1应选B;例2应选C。现在完成时常与recently(近来),so far(到目前为止),in the past/“last + 一段时间”等时间状语连用。因为上述短语表示的是从现在起往前推算的一段时间,句中

38、的动作是从过去某一时间或时刻开始持续到现在的。故例3应选D,例4应选C。现在完成时时常与“for +时间段或since +过去时间点”连用(含从句,从句过去时)。故例5应选C,例6应选C。现在完成时还与once(一次),twice(两次),three times(三次),several times(几次)等表示重复次数的词语连用。故例7应选B。考点三:考查与一般过去时的区别例1. These farmers have been to the United States . Really ? When _ there ?. will they go . did they go. do they

39、go . have they gone 例2._ you _ your homework yet ? Yes . I _ it a moment ago . Did ; do ; finished . Have ; done ; finished. Have ; done ; have finished . will ; do ; finish简析:现在完成时与一般过去时容易混淆,就是因为它们所表示的动作都发生在过去,但二者又有区别:一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作,说话的侧重点在于陈述一件过去的事情,与现在没有关系;现在完成时表示与现在有关系的发生在过去的动作,

40、它不与表示过去的时间状语(如yesterday , last week , a moment ago等)连用。故例、的正确答案皆为B。考点四:考查非延续性动词的用法例1. His father _ the Party since 1978 . joined . has joined . was in . has been in例2.Do you know him well ? Sure .We _ friends since ten years ago . were . have been . have become . have made例3.How long have you _ here

41、 ?About two months . been . gone . come . arrived例4. Hurry up! The play _ for ten minutes . has begun . had begun. has been on . began例5. His uncle died two years ago .(改变句子,句意不变)His uncle has _ _ for two years 例6. Her mother has been a Party member for three years .(同义句)Her mother _ the Party three

42、 years _ .例7. It _ ten years since he left the army . is . has . will . was简析:现在完成时中,非延续性动词不能与for和since引导的表示一段时间的状语连用,通常是用相应的延续性动词来代替。常用的非延续性动词及替代形式如下:closebe closed, put onwear , openbe open get upbe up, finish/endbe over , losebe lost , marrybe married(to), fall asleep/ go to sleep be asleep ( sle

43、ep ) , get to know know come/arrivebe here/in , come/get backbe back , go/leave-be away , become be , borrow keep , buyhave , begin/startbe on , diebe dead , joinbe in/be a ember of , catch a cold have a cold等,故例1、2、3、4的正确答案依次为:D、B、A、C。例5应填been dead 。其次,可以用相应的延续性动词的过去时表示,故例6应填joined;ago。再次,还可用“It is

44、 + 一段时间since从句”来表示,故例应选A。考点五:考查词组have/has been in / to与have/has gone to的区别例1. Miss Green isnt in the office . she_ to the library .has gone . went .will go . has been例2. My parents _ Shandong for ten years . have been in . have been to. have gone to .have been简析:“have/has gone to + 地点”表示“某人去了某地(还未回来

45、)”,指主语所指的人不在这儿。“have/has been in + 地点”表示“在某地呆了多长时间”,常与表示时间的状语连用。“have/has been to +地点”表示“曾经去过某地(但现在已不在那儿)。”故例1、2的正确答案皆为A。要点提示:1 结构:have/has+done 表示过去发生的某个动作对现在产生的影响,或过去发生的某个动作持续到现在。2 have/has been to 与have/has gone to的辨析have/has been to 表示“曾去过”,说明有某种经历。have/has gone to 表示“已去某地(在途中或已到目的地)”。e.g. She h

46、as been to Canada. 她去过加拿大。 She has gone to Canada. 她去加拿大了。3 瞬间动词与延续性动词1)瞬间动词表示短暂。不能持续一段时间的动作,如:come, leave, begin, become, buy, receive, die, join, borrow, lend, go,等。2)持续性动词表示能持续一段时间的动作,如:work, stay, live, learn, read, write, wait 等3)瞬间动词用于完成时表示动作的完成。e.g. She has already bought a dictionary. 她已经买了一

47、本字典。4)瞬间动词不能与表示一段时间的状语连用。e.g. She has left Shenyang. She has left Shengyang for a month. She has been away from Shenyang for a month.但是瞬间动词的否定结构可以与表示一段时间的状语连用,说明某动作不发生的状态可以持续一段时间e.g. She often goes on business. But she hasnt left Shenyang for a month./since a month ago.过去进行时过去进行时由was/were加现在分词构成,表示过

48、去某个时刻或某一阶段正在进行的动作。常与表示过去某一时间的状语或when引导的谓语动词是一般过去时的时间状语从句连用。如: What were you doing at this time yesterday? My mother was cooking when I got home. 过去将来时过去将来时由should/would加动词原形或was/were going to加动词原形构成,表示 从过去某时看来将要发生的事情,常用在宾语从句中。如: I didnt know when he would come back. 过去完成时过去完成时由had加过去分词构成,表示过去某一动作或时间

49、以前已发生或完成的动作,也可指从过去某时开始到过去另一时为止的动作或状态,即“过去的过去”。常用的时间状语有:a. by last month, by the end of last term等;b. before he came here, when I got there等。如: By the end of last term they had learned about twenty English songs. The film had already begun when we got there. 注意:before与ago的用法有区别。before表示“距过去某时以前”,即过去的

50、过去,用于过去完成时;ago表示“距今以前”,即从现在起的过去,用于一般过去时。 第二节 实战演练一、例题选讲例1Look, she (have) a bunch of flowers in her hand.答案:has提示:尽管句中有look,但在英语中表示“有”,不能用进行时态,本句意思指“她手中有一束花”。例2John (make) much progress in his lessons since last term. He (study) harder later on.答案:has made, will/is going to study提示:第一句中,since last t

51、erm暗示了谓语动词要用现在完成时态。说明从上学期以来取得了很大进步,第二句中的later on要注意用一般将来时。例3Cherry arrived at school after the class (begin) yesterday. 答案:had begun提示:begin虽然也能作及物动词,但在表示某事开始时,一般以不及物动词出现,不用被动结构。例4If it (not rain) tomorrow, we (go) to the park.答案:doesnt rain, will go提示:这是条件状语从句,主句是将来时,其时间或条件状语从句应用一般现在时。例5Great chang

52、es (take) place in Shanghai in the past ten years.答案:have taken place提示:In the past ten years会造成过去时间感觉,但其意思是近十年中,与现在有关,要用现在完成时例6It is said that they (hold) an English evening next week.答案:will hold提示:主句It is said是现在时时态,从句要用将来时,不能用过去将来时。补充:初中英语词汇精讲:when,while,as的用法三者可表示“当时候”,区别如下:1.若主句表示的是一个短暂性动作,从句表

53、示的是一个持续性动作,三者都可用:Hefellasleepwhenwhile,ashewasreading.他看书时睡着了。【注】as用于引出一个持续性动词表示“在期间”时,其谓语通常不能是那些不用于进行时态的动词(如be,seem,love,want,agree,see,know,have等),所以下面一句中的while不能换为as:A:Imgoingtothepostoffice.我要去邮局。B:Whileyourethere,canyougetmesomestamps?当你在邮局时,能帮我买几张邮票吗?2.若主、从句表示两个同时进行的持续性动作,且强调主句表示的动作延续到从句所指的整个时

54、间,通常要用while:Ikeptsilentwhilehewaswriting.在他写的时候,我默不作声。但是,若主从句表示的两个同时进行的动作含有“一边一边”之意思,通常用as:Shesangasshewentalong.她边走边唱。3.若从句是一个短暂性动作,主句是一个持续性动作,可用as/when但不用while:Itwasraininghardwhenaswearrived.我们到达时正下着大雨。4.若主从句表示的是两个同时(或几乎同时)发生的短暂性动作,用as/when:Ithoughtofitjustwhenasyouopenedyourmouth.就在你要说的时候,我也想到了。

55、5.若要表示两个正在发展变化的情况,相当于汉语的“随着”,一般用as:Thingsaregettingbetterandbetterastimegoeson.随着时间的推移,情况越来越好。Asitgrewdarker,itbecamecolder.天色越晚,天气越冷。6.表示“每当的时候”(暗示一种规律性),一般要用when:Itscoldwhenitsnows.下雪时天冷。Hesmileswhenyoupraisehim.你夸奖他时他总是笑笑。7.若主从句所表示的动作不是同时发生,而是有先后顺序时,一般要用when:Iwillgohomewhenhecomesback.他回来时,我就回家去。8.when可用作并列连词,表示“这时(突然)”;while也可以用作并列连词,表示“而”、“却”(表示对比);但as则没有类似用法:Wewereabouttostartwhenitbegantorain.我们正要出发,这时天开始下雨了。Helikescoffee,whileshelikestea.他喜欢咖啡,而她却喜欢茶。
