我想知道情态动词反问疑问句的几种用法
If you_ to come,do any time.
a.careful b.carefully c.care d.careless
这道题问什么选C?
最佳答案
一般情况下是和普通反意疑问句一样,在情态动词上改,比如.

You can play piano, can't you?
He can't go to school today, can he?

但注意下列情况:

1 当陈述部分带有情态动词ought to时,反意疑问部分在英式英语中用ought to 形式,在美式英语中用should形式。例如:

You ought to see the new picture,shouldn't you?

Teachers ought to be honoured,oughtn't they?

2 当陈述部分带有情态动词used to时,反意疑问部分可以用used to形式,也可以用did形式。例如:

She used to live abroad,usedn't she?

There used to be a newsstand in the corner of the street,didn't there?

3 当陈述部分带有情态动词must时,反意疑问部分需视must的含义而定。

a.当must表示“命令或强制”时,反意疑问部分用mustn't。例如:

You must do it by yourself,mustn't you?

b.当must表示“有必要”时,反意疑问句用needn't,例如:

You must see him tonight,meedn't you?

c.当must表示“一定”或“想必”等推测意义时,反意疑问部分不用mustn't,而根据must后的动词形式而定。例如:

He must be crazy to do so,isn't he?

She must have been there for a long time,hasn't she?

They must have stayed at home last might,didn't they?

4 当陈述部分带有need时,反意疑问部分需视need的含义而定。如果need用作情态动词,则反意疑问部分用need形式;如果need用作实义动词,表示“需要”,则反意疑问部分用do形式。例如:

You needn't go there,need you?

She needs to fo there,doesn't she?

Plants need sun to grow,don't they?
全部回答
一般情况下,直接反问情态动词就可以了 但是提醒几点: need 有实意动词,情态动词,实意时注意要用do,does反问 must的否定反问一般用needn't不是mustn't have要注意区分助动词,实意动词(这个不是情态动词哈)
careful careless 为形容词 carefully为副词 care理解为动词 而句中come为动词,前面有to 应遵循两个动词之间加to,所以只能选动词care 也可以这样理解 care +v(动词)意为愿意,喜欢,要 eg:Would you care to go to dinner? 你愿意出去吃饭吗? 整句话的意思为 如果你愿意,你任何时候来
情态动词有五类: ①只做情态动词:must,can(could),may(might), ②可做情态动词又可做实义动词:need,dare ③可做情态动词又可做助动词:shall(should),will(would) ,ought to ④具有情态动词特征:have(had,has) to,used to ⑤情态动词表猜测 [编辑本段]位置 情态动词有一定的词义,但并不完整,必须与动词原形一起构成谓语。 I can see you. Come here. 我能看见你,过来吧。 He must have been away. 他一定走了。 What can I do for you? 我能帮你吗? How dare you treat us like that! 你怎能那样对待我们! [编辑本段]特点 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。 个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在或将来。情态动词属非及物动词,故没有被动语态。 He could be here soon. 他很快就来。 We can't carry the heavy box. 我们搬不动那箱子。 I'm sorry I can't help you. 对不起,我帮不上你。 基本助动词与情态助动词最主要的区别之一是,基本助动词本身没有词义,而情态助动词则有自己的词义,能表示说话人对有关动作或状态的看法,或表示主观设想: What have you been doing since? (构成完成进行体,本身无词义) I am afraid I must be going. (一定要) You may have read some account of the matter. (或许已经) 除此之外,情态助动词还有如下词法和句法特征: 1) 除ought和used以外,其他情态动词后面只能接不带to的不定式。如果我们把ought to和used to看做是固定词组的话,那么,所有情态动词无一例外地只能接不带to的不定式: We used to grow beautiful roses. I asked if he would come and repair my television set. 2) 情态助动词在限定动词词组总是位居第一: They need not have been punished so severely. 3) 情态助动词用于第三人称单数现在时的时候,没有词形变化,即其词尾无-s形式: She dare not say what she thinks. 4) 情态动词没有非限定形式,即没有不定式和分词形式,也没有相应的动名词: Still, she needn't have run away. 5) 情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合,情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间: Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6) 情态助动词之间是相互排斥的,即在一个限定动词词组中只能出现一个情态助动词,但有时却可以与have和be基本助动词连用: You should have washed the wound. Well, you shouldn't be reading a novel. [编辑本段]用法 首先它是动词,而且不同于行为动词,行为动词表示的是可以通过行为来表达的动作(如写,读,跑),而情态动词只是表达的一种想法(如能,也许,敢)。 用法是:情态动词+行为动词原形 例句:I can read this sentence in English. 我能用英语读这句话。 情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语。 We can be there on time tomorrow.我们明天能按时去那儿。 May I have your name? 我能知道你的名字吗? Shall we begin now?我们现在就开始吗? You must obey the school rules.你必须遵守校规。 情态动词数量不多,但用途广泛,主要有下列: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would),have (to) ,had better. 情态动词还有一个很重要的用法,即情态动词表推测—— 情态动词表推测的用法小结 (一)情态动词表推测的三种句式 1.在肯定句中一般用must (一定),may(可能),might / could(也许,或许)。 (1)He must/may/might know the answer to this question? 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room. They must have turned off the heating. 屋里很冷,他们肯定把暖气关了。 2.否定句中用can’t / couldn’t(不可能), may not/might not(可能不)。 (1)It can’t/couldn’t be the headmaster. He has gone to America. 这不可能是校长,他去美国了。 (2)He may not/might not know the scientist. 他也许不认识那位科学家。 3.疑问句中用can/could (能……?)。 (1)Could he have finished the task? 他可能把任务完成了吗? (2)Can he be at home now? 他现在能在家吗? 注:以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式,而表示语气较为委婉或可能性较小。 (二)情态动词表推测的三种时态 1.对将来情况的推测,用“情态动词 + 动词原形”。 (1)She must / may / might / could arrive before 5. 5:00前她一定/可能/也许到。 (2)She must/may/might/could walk miles and miles among the hills without meeting anyone. 她一定/可能/也许会在山里一连走好几英里而遇不到一个人。 2.对现在或一般情况的推测,用“情态动词 + be”,“情态动词 +be doing”或“情态动词 + 动词原形”。 (1)He must / may / might / could be listening to the radio now. 他一定/可能/也许正在听收音机。 (2)He can’t ( couldn’t ) / may ( might ) not be at home at this time. 这个时候他不可能/可能不在家。 (3)Mr. Bush is on time for everything .How can ( could ) he be late for the opening ceremony ? 布什先生一向准时,这次开幕式他怎么可能迟到呢? 3.对过去情况的推测,用“情态动词 + have +过去分词”。 (1)It must / may / might / could have rained last night .The ground is wet. 地湿了,昨晚肯定/可能/也许下雨了。 (2)The door was locked. He can ( could ) not / may ( might ) not have been at home . 门锁着,他不可能/可能不在家。 (3)Can / Could he have gotten the book? 难道他找到书了吗? 注:情态动词 should /ought to表推测时,意为“想必会,理应……”但与“have +过去分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。例如: (4)It’s seven o’clock. Jack should/ought to be here at any moment. 现在七点钟了,杰克理应随时到达。(推测) (5)She should / ought to have attended your birthday party, but she had to look after her mother in hospital. (虚拟) 她本该出席你的生日晚会的,可是她得在医院照顾她妈妈。 (6)Tom should not /ought not to have told me your secret, but he meant no harm. (虚拟) 汤姆本不该告诉我你的秘密,可是他并无恶意。 2、反意疑问句用法说明 ◇注意: 反意疑问句前后两部分谓语应是,“肯定陈述+否定疑问”或“否定陈述+肯定疑问” 简略问句如果是否定式,not应与be,do,will等系动词、助动词、情态动词缩写 简略问句的主语不用名词,应用人称代词 当说话者的目的不在疑问,而是为了加强语气时,用降调 当说话者的目的在疑问,则用升调 陈述部分含“too...to”时,是否定句 1) 陈述部分的主语是I,疑问部分要用 aren't I. I'm as tall as your sister,aren't I? (我和你姐姐一样高,对吗?) 2) 陈述部分的谓语是wish,疑问部分要用may +主语。 I wish to have a word with you, may I? (我希望可以和你说话,可以吗?) 3) 陈述部分用 no, nothing, nobody, never, few, seldom, hardly, rarely, little等否定含义的词时,疑问部分用肯定含义。 The Swede made no answer, did he / she? Some plants never blown (开花), do they ? 4) 含有ought to 的反意疑问句,陈述部分是肯定的,疑问部分用shouldn't / oughtn't +主语。正式文体用should/ought +主语+not形式。 He ought to know what to do, oughtn't he? / shouldn't he? 5) 陈述部分有have to +v. (had to + v.),疑问部分常用don't +主语(didn't +主语)。 We have to get there at eight tomorrow, don't we? 6) 陈述部分的谓语是used to 时,疑问部分用didn't +主语或 usedn't +主语。 He used to take pictures there, didn't he? / usedn't he? 7) 陈述部分有had better + v. 疑问句部分用hadn't you? You'd better read it by yourself, hadn't you? 8) 陈述部分有would rather +v.,疑问部分多用 wouldn't +主语。 He would rather read it ten times than recite it, wouldn't he? 9) 陈述部分有You'd like to +v. 疑问部分用wouldn't +主语。 You'd like to go with me, wouldn't you? 10) 陈述部分有must 的疑问句,疑问部分根据实际情况而定。 A.must表示“应该”,其疑问部分用mustn't(不应该),如: You must work hard next term, mustn't you ? 下学期你应该努力学习,对吗? B.must表示“必须”,其疑问部分用needn't(不必),如: They must finish the work today, needn’t they? 他们今天必须要完成这项工作,是吗? C.陈述部分含情态动词mustn't,表示禁止时,疑问部分就可以用must或may,如: You mustn’t stop your car here, must you? (may we?)你不能把车停在这地方,知道吗? D.must表示推测 ,其疑问部分必须与must 后面的主要动词相呼应。如: ①对现在动作或存在的情况的推测 : You must know the answer to the exercise, don't you? 你一定知道这项练习的答案,是不是? That must be your bed, isn't it? 那一定是你的床,是吗? ②对过去发生的动作或存在的情况的推测: a 表示肯定推测 (一)句中陈述部分没有表示过去的时间状语,这时疑问部分中的动词就用 现在完成时。(haven’t / hasn’t + 主语) You must have told her about it, haven’t you? 你一定把这事告诉她了,是吗? (二)陈述部分有表示过去的时间状语,疑问部分的动词就用 一般过去时。(didn’t + 主语) She must have read the novel last week, didn’t she? 她上星期一定读了这本小说了,是吗? b 表示否定推测 表示推测时,否定式通常不是must not,而是can't (cannot).如: He can't have been to your home; he doesn't know your address, does he? 他不可能去过你家;他不知道你的地址,是不是? 11) 感叹句中,疑问部分用be +主语。 What colours, aren't they?
