第1章 动词的时与体(Tense & Aspect) 时(tense)是个语法范畴,它是 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 示时间区别的动词形式。 英语 关于好奇心的名言警句英语高中英语词汇下载高中英语词汇 下载英语衡水体下载小学英语关于形容词和副词的题 动词只有“现在时”和“过去时”,而没有“将来时”(在英语中,表示“将来”手段多种多样,但没有一种独特的、能与“现在时”和“过去时”平起平坐的专一表示“将来”的动词形式----“将来时”)。 体(aspect)也是一个语法范畴,它表示动作或过程在一定时间内处于何种状态的动词形式。英语有进行体(progressive aspect)和完成体(perfective aspect)。进行体是由助动词be的一定形式加主动词的-ing分词构成;完成体由助动词have的一定形式加主动词的-ed分词构成。 现在时和过去时既可以单独使用,也可以和进行体或完成体结合使用,也可以同时与完成体和进行体结合使用。这样,英语的限定动词词组便有8种时、体形式。它们分别是:一般现在时(simple present)、一般过去时(simple past)、现在进行体(present progressive)、过去进行体(past progressive)、现在完成体(present perfective)、过去完成体(past perfective)、现在完成进行体(present perfective progressive)、过去完成进行体(past perfective progressive)。在这一章中,我们单独挑出完成体来加以详述。 1.1 必须使用完成体的结构 1)It (This, This evening, yesterday...) is (was, will be) first (second, third...) time (day, month…)…结构中的分句,要求用完成体。 Is this the first time you've been to Beijing? This was the first time he had been to Beijing. This is the eighth month that I have been out of work.. This was the eighth month that I had been out of work. This is the second time that the goods produced by our factory have been shown in the International Exhibition. This was the second time that the goods produced by our factory had been shown in the International Exhibition. 2)在no sooner…than, hardly/barely/scarcely…when,等的句型中,主句要用过去完成体。 He had no sooner seen me than he left the room. No sooner had he seen me than he left the room. The helicopter had hardly landed when the waiting crowd ran toward it. Scarcely had I seen the lightning when I heard a clap of thunder. 3)将来完成体用来表示在将来某一时间以前已经完成或一直持续的动作。经常与before+将来时间或by+将来时间连用,也可与before或by the time引导的现在时的分句连用。 I will have finished all the work by the time you are back this evening. I am sure he will have left Paris by this time tomorrow. I hope we will have got all the information before you come tomorrow. By the time you get to New York, I _______for London. (2002年1月)   A) would be leaving   B) am leaving C) have already left    D) shall have left 本 快递公司问题件快递公司问题件货款处理关于圆的周长面积重点题型关于解方程组的题及答案关于南海问题 时间状语为by+将来时间,考察将来完成体用法,应选择D)。 By the time he arrives in Beijing, we ________here for two days.(2001年6月) A) have been staying B) have stayed C) shall stay D) will have stayed   将来完成体用来可以表示在将来某一时间以前一直持续的动作,本句话的意思是:我们将在这里呆两天,因此谓语动词用将来完成体,答案为D)。 1.2 现在完成体与现在完成进行体 现在完成进行体兼有现在完成体和现在进行体二者基本特点。由于它有现在完成体的特点,所以它可以表示某一动作对现在产生的结果或影响。由于它有现在进行体的特点,所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。 1)现在完成进行体和现在完成体皆可表示动作对现在产生的结果,但前者所表示的结果是直接的,而后者所表示的则是最后的结果。 We have been cleaning the classroom.(a) We have cleaned the classroom.(b) (a)句可译为“我们打扫教室来着”。其直接结果可能是:我们身上都是灰。(b)句可以译为“我们把教室打扫过了”。其结果是:现在教室很清洁,可以用了。另外(a)句表示教室刚刚打扫过,(b)句则可能表示教室是昨天打扫的。再看下面两个句子: Be careful! John has been painting the door.(a) John has painted the door.(b) (a)句表示约翰刚刚把门油漆过,现在油漆还未干,所以你要小心。(b)句则无此含义,油漆可能已干了。 2)现在完成进行体有时有延续性;现在完成体往往没有。 They have been widening the road.(a) They have widened the road.(b) (a)句的意思是他们在加宽马路,但尚未完工。(b)句的意思则是已完工了。有时现在完成体有延续性(如一些属于持续体的动词),但无临时性质。 Mr. Smith has been living in London since 1978.(a) Mr. Smith has lived in London since 1979.(b) (a)句有“史密斯先生在伦敦久居”的含义,(b)句则没有。 3)但现在完成进行体并不总是具有临时的性质。 My mother has been teaching English for twenty years.(a) My mother has taught English for twenty years.(b) (a)句在此并无临时性质,但较口语化。(b)句则较为正式。另外,(a)句表示动作现在仍在继续.并将延续下去;(b)句的动作是否延续下去,须由上下文决定,但在一般情况下都是延续下去的。 4) 在完成进行体往往表示动作在重复;现在完成体则常常不带重复性。 Have you been meeting her lately?(a) Have you met her lately?(b) (a)句有“经常相会”之意,(b)句则没有。(b)句如与often,every day等时间状语连用,当然也表示动作在重复。 5) 在否定结构中,现在完成体所否定的是谓语动词;现在完成进行体所否定的是状语。 He hasn't been speaking since three o'clock.(a) He hasn't spoken since three o'clock.(b) (a)句中所否定的不是has been speaking,而是 since three o'clock,其结构等于 He has been speaking not since three o'clock but since half past three.这是因为现在完成进行体本身是没有否定结构的原故。(b)句用的是现在完成体,而现在完成体是有否定结构的,所以(b)句中所否定的自然是has spoken,意即“从三点起他一直沉默不语,未发一言”。 1) 1.3情态动词 + 行为动词完成体 2) must + have + V-ed 指现在对过去已发生的事或可能出现的情况进行推断和猜测,表示推测过去某事“一定”发生了。因此,You must see her last night的说法是错误的。 She must have met a ghost yesterday. 她昨天一定碰见过鬼了。 He must have been there last week.他上周一定在那儿。 His score on the English test is the highest in the class; he must have studied last night.他这次英语测试的成绩全班最高。他昨晚一定在好好学习。 3) can’t/couldn’t + have + V-ed can’t/couldn’t + have + V-ed为must + have + V-ed的否定形式,指现在对过去已发生的事或可能出现的情况进行推断和猜测,表示过去不可能发生某事。 They can’t have come here in their car yesterday, for it was then under repair.他们昨天不可能开车到这里,因为那时他们的车还正在修理当中。 The room is in a mess; it can’t/couldn’t have been cleaned. 4) may/might + have + V-ed 表示推测过去某事“也许”发生了。 He may/might have chosen another career if he had had enough money to further his education.如果他那时有足够的钱继续受教育,他也许会选择另一个职业。 I might have fulfilled the work earlier. 我本可以早一些完成这件工作的。 5) ought to/should + have + V-ed和ought not/shouldn’t + have + V-ed 对以发生的情况表示“不满”、“责备”,分别表示“本应该…”和“本不应该” I wonder why they haven’t arrived yet. I told them how to get there, but perhaps I ought/should give them a map.(含有“后悔”或“自责”之意) You ought to have told me that yesterday.你早在昨天就该把那件事告诉我了。 6) needn’t + have + V-ed 表示过去做了某事,但没有做的必要,意为“本没必要…”。 You needn’t have hurried. She needn’t have come in person--- a letter would have been enough. You needn’t have done all those calculations. We have a computer to do that sort of thing. 1. 4用在was/were, planned, intended, hoped, wished + 不定式完成体 表示事实上并未实现的计划或行为。(详见3.3不定式完成体) We were to have started at 8 last night, but it snowed heavily. They intended to have gone camping, but they later cancelled it. I hoped to have finished it last week, but I was too busy. 练习 1.

(a) → It is thought that she is honest. (b) → She is thought to be honest. (c) (b) 以it作形式主语,将(a)中的动词变为被动态,保留(a)中的that分句;(c)将分句的主语变成被动句中的主语,将(a)中的动词变为被动态,再将(a)中的that分句改为不定式短语,放在被动态后面。能这样用的动词主要有:think, consider, assume, suppose, say, report, acknowledge, feel, believe, find, presume, know, understand, etc. 如果that分句的动词是进行体,这时分句要改为不定式进行体。 They suppose that she is coming. → It is supposed that she is coming. → She is supposed to be coming. They supposed that she was coming. → It was supposed that she was coming. → She was supposed to be coming. 如果that分句的动作或状态发生在主句之前,这时分句要改为不定式完成体。 People feel that little was done to prevent the accident → It is felt that little was done to prevent the accident. → Little is felt to have been done to prevent the accident. They report that both sides have reached an agreement. → It is reported that both sides have reached an agreement. → Both sides are reported to have reached an agreement. People think that she was honest. → It is thought that she was honest. → She is thought to have been honest. 2.3 短语动词的被动语态 短语动词通常被视为一个整体,转化为被动语态时,词组内的介词、副词、名词等不能拆散或省略。 The old house will be pulled down tomorrow. The little boy was made use of by the drug-pusher to carry drugs for him. That sort of thing should be done away with. The sports meet is to be put off. 另外,有些短语动词不能用被动语态,如:take place, look like, belong to, depend on, consist of, agree with等。 The accident took place yesterday on the expressway. He looks like an old man. The honor belongs to us. He is the person to depend on. 练习 1. The shirt smooth. A) is felt B) is feeling C) feels D) is to be felt 2.

A) are stood B) have been stood C) stand D) standing 第三章 不定式(Infinitive) 3.1不定式在句子中充当的作用 1)作主语 不定式作主语:一般表示具体的某次动作。   To complete the 30-storied building in one year was quite a difficult task. To do that implies taking responsibility. For there to be so modern a library in this rural area is surprising.   当主语较长,谓语较短时,常用it做形式主语,而将不定式放到谓语的后面。   It is important for modern young people to master at least two foreign languages.   It做形式主语,不定式放在谓语动词之后常用于下列结构中:   a) It is+形容词(easy, important, difficult, foolish, inconvenient, unnecessary, right, wrong...)+( for/of sb.)+不定式 It is essential to reserve a table in advance of Christmas Eve.   It is hard to put my hopes into words.   It is not easy to catch fish with your hands only.   It is important for us young people to learn English and master it.   b) It is+名词(a pleasure, a pity, a pleasant thing, one's duty, an honor, a shame, a crime, no easy job...)+不定式   It is a sheer waste of time to read that kind of trash.   It is a pity to have to go without her.   It is a glorious death to die for the people. c) It takes/took (sb.) some time (hours, months, days, a lot of time, patience...)+不定式   It takes me three hours to learn English each day. It took them half the night to get home in the snow. 2)作表语 不定式作表语,常表示将来的动作,主语常常是表示意向、打算、计划的词,如wish, idea, ask, purpose, duty, job等。    The most important thing for one's health is to have plenty of exercise.    My chief purpose has been to point out the difficulties of the matter.    The purpose of the organization is to greet all new comers to the city and to provide them with any necessary information. What I wanted was to get the work done as quickly as possible. 注意:当主语中有do的任何形式时,作表语的不定式中的to通常省略。 What he wants to do most is (to) enjoy himself every day. What they did last night was (to) play cards to their heart’s content. 3)作宾语 不定式作宾语,通常用在下列结构中: a)“动词+不定式”结构:不定式直接跟在动词后面。 这类动词有:afford, agree, apply, arrange, ask, attempt, beg, begin, care, choose, claim, consent, demand, decide, desire, determine, expect, fail, hope, hesitate, hate, intend, learn, like, manage, mean, neglect, offer, plan, prepare , pretend, promise, refuse, resolve, seek, tend, threaten, want等。 I like to go out for walks in the warm sunshine in spring. My mother hates to move from place to place, for she feels tired. I decide to work hard and get a doctor's degree.   She failed to finish the assignment in time, and she was worried about it.   There is a man at the reception desk who seems very angry and I think he means to make trouble. I’d like there to be a room of my own. I don’t want there to be any misunderstanding between us.   b) 不定式作宾语还常用在下面结构中“主语+动词+it+形容词+不定式” We found it impossible to get everything ready in time. I think it important to learn English well in college. 使用这种句型的常见动词有:believe, consider, declare, feel, find, guess, imagine, prove, realize, suppose, think,等。 c) “wh-+不定式”结构 不定式前加一个疑问代词(what, which, who, whom, whose)或疑问副词(where, when, how, why),以及连词whether构成特殊的不定式短语,其作用相当于一个分句,这样的不定式短语常在某些动词后面作宾语。常见的可以接这种不定式短语的动词有:know, see, decide, tell, ask, consider, discover, explain, find out, forget, guess, hear, imagine, inquire, learn, observe, perceive, remember, think, understand, wonder等。 I couldn't decide which book to choose. I can tell you where to get this book. They found it hard to decide whether to go swimming next Sunday or to visit Aunt Sally. “wh-+不定式”结构除了作宾语外,还可以在句中作主语或者表语。   When to start the program remains undecided. The question is how to put the plans into practice. 4)作状语 a) 不定式作状语表示目的。或用于so as (not) to和in order (not) to之后,来强调这种目的。   To learn a foreign language well, you must make painstaking efforts.   Mother saved every cent she could spare to pay for my schooling. We must develop science and technology at high speed so as to raise scientific and cult
