(= Should you fail to come,ask Mrs Chen to work in your place. )万一你来不了,就叫陈夫人代替你。 If anyone should come,say I am not at home. (= Should anyone come,say I am not at home. )万一有人来访,就说我不在家。 If it should rain tomorrow,I wouldn't go.

(完整版)情态动词详细用法归纳

情态动词详细用法归纳 情态动词有具体的词义,但也同助动词一样,需要与其他词语一起构成句子的谓语,另外情态动词没有人称和数的变化,情态动词后必须跟动词原形。 1. can 的用法: (1)表示能力、许可、可能性。表示能力时一般译为“能、会”,即有种能力,尤其是生来具备的能力。 如:She can swim fast, but I can’t . 她能游得很快,但我不能。 could是can的过去式。表示过去的能力。be able to do sth. 常常指经过努力,花费了时间和劳力之后才能做到某事。 (2)表示许可,常在口语中。 如:You can use my dictionary. 你可以用我的字典。 (3)表示推测,可能性,意为“可能”,常用于否定句和疑问句中,此时can’t 译为“ 不可能”。如:Can the news be true? 这个消息会是真的吗? —Can it be our teacher?那个人有可能是我们老师吗? —No, it can’t be our t eacher. He is on a visit to the Great Wall.不可能。咱们老师正在游览长城呢。【例题】—I think Miss Gao must be in the library. She said she would go there. —No. She be there, I have just been there.

情态动词的基本用法及其区别

情态动词的基本用法及其区别 最近几年高考试题中常常借助语境来考查情态动词的基本用法及其区别,因此在平时学习时准确理解和掌握情态动词的基本用法十分重要。情态动词的用法复杂多变,在高考试题中,命题者常常利用语境和句子之间意义上的细微差别来考查学生对情态动词的理解和掌握。对于情态动词,除了要求考生能够准确掌握它们的基本用法外,还要充分利用高考试题所设置的语境来分析句子之间所体现的特殊关系。下面就近几年来高考试题中出现的情态动词的考点进行归纳分析,以便同学们复习掌握。 一、用“情态动词+have +done”结构表示对过去动作的推测,高考试题中常用过去时态或过去的时间状语给以暗示。情态动词的这一用法可以用“对立统一”来概括。 1.当试题的前句和后句在动作和意义上相互补充说明,且整个句意在动作和时间上是一个整体时,我们可用“统一”关系来解决这样的试题。常见的结构有: must have done: 表示对过去动作的肯定推测,常译作“一定做了……”,只能用于肯定句中。其否定形式为can’t/couldn’t have done 疑问式为Can/Could...have done﹖。 could /might have done:表示对过去发生的动作的可能性推测,常译作“可能做了……”。如: 1) My sister met him at the Grand Theater yesterday afternoon, so he _____your lecture. A.couldn’t have attended B.needn’t have attended C.mustn’t have attended D.shouldn’t have attended 本题选A。 2) Jack ____yet, otherwise he would have telephoned me. A.mustn’t have arrived B.shouldn’t have arrived C.can’t have arrived D.need not have arrived (C) 2.当试题的前后句在动作和意义上构成转折关系时,常借助“but, however, instead”等词来表示过去的动作与客观事实不符,这时我们就可以用“对立”关系来解决这样的试题。这种结构常见的有: should have done /ought to have done:表示过去本应该做某事而实际上没有做。 should not have done /ought not to have done:表示过去本不应该做某事但事实上却做了。 need have done:表示过去本来有必要去做某事,但事实上没有做。 need not have done:表示过去本来没有必要做某事,但事实上却做了。如: 3) I was really anxious about you.You _____home without a word.(NMET2001) A.mustn’t leave B.shouldn’t have left C.couldn’t have left D.needn’t leave “本不应该离家出走却走了”,故本题选B。 4) I told Sally how to get here, but perhaps I _____for her.

情态动词should的用法

情态动词should的用法 情态动词should和can ,may ,must一样,没有人称和数的变化,有词意,但都不能单独作谓语,必须和后面的动词原形一起构成谓语。基本意思是“应当,应该”,常用来表示建议或命令等。如: You should work harder. 你应该更努力地工作。 否定式和疑问式的构成与can ,may ,must一样。如: You shouldn’t play soccer in the street.你们不应该在街上踢足球。 Who should pay the taxi driver? 谁应该付出租车钱? 注意: 常用句型You should /shouldn’t do sth 表示“建议某人(不)做某事”。其他表示“建议”的句型还有:Why not do sth? /Why don’t you do sth? /How about doing sth? /What about doing sth? /It’s a good idea to do sth /You’d better do sth等。 should作为情态动词用,常常表示意外、惊奇、不能理解等,有“竟会”的意思,例如: How should I know? 我怎么知道? Why should you be so late today? 你今天为什么来得这么晚? should有时表示应当做或发生的事,例如: We should help each other.我们应当互相帮助。 我们在使用时要注意以下几点: 1. 用于表示“应该”或“不应该”的概念。此时常指长辈教导或责备晚辈。例如: You should be here with clean hands. 你应该把手洗干净了再来。 2. 用于提出意见劝导别人。例如: You should go to the doctor if you feel ill. 如果你感觉不舒服,你最好去看医生。 3. 用于表示可能性。should的这一用法是考试中常常出现的考点之一。例如: We should arrive by supper time. 我们在晚饭前就能到了。 She should be here any moment. 她随时都可能来。 1. We _________ keep the new traffic law(交通法). A. may B. should C. can D. need 2.I’d like to buy a new shirt , but I don’t know __________ . A. where could buy it B. I should take which C. which I should take D. where can I get it 写出同义表达 Why not have a rest? (1) Why _______ ________ have a rest? (2) You’d _________ _________ a rest.

情态动词的用法 一.can和could 特别提示: (1)could用来表示请求时,语气委婉,主要用于疑问句,不能用于肯定句,回答应该用can(即:could不能用于现在时态的简略答语中)。如: ——Could I use your dictionary? ——Yes, you can.(否定回答可用:No, I’m afraid not.) (2)can和be able to区分 can(could)和be able to都可以表示能力,意思上没有区别。但can只有现在式和过去式,而be able to则有更多的形式。如: I’ve always wanted to able to speak fluent English. Those bags look really heavy, are you sure you’ll be able to carry them on your own? 但是,表示在过去某时的某一场合经过一番努力,终于做成了某事,通常不用could,而用was/were able to来

表示。这时,was/were able to相当于managed to do或succeed in doing。如:After the accident it was a long time before she was able to walk again. The fire was very big, but most people were able to escape from the building. (3) 惯用形式“cannot …too…”表示“无论怎么……也不(过分)”。如: You cannot be too careful.你越小心越好。 惯用形式“cannot but+ 不定式(不带to)”表示“不得不,只好”。如: I cannot but admire her determination.我不得不钦佩你的决心。 二.may和might 二.must和have to
