    情态动词有什么用法 怎么用

    常用的情态动词有:can(could)、may(might)、must、need、ought to、dare(dared)、will(would)等等。下面是情态动词的相关用法,来看一下! 情态动词的用法 1.表推测及可能性。may,might,can, could, will, would表示“可能”或“预测;, shall, should用于表示“必定”;must用于表示“必定”,“必会“;ought to表“应该为”。 2.与时态相关。can为现在式,其过去式 为could;may为现在式,其过去式 为might;shall为现在式,其过去式 为should;will为现在式,其过去式 为would. 3.表示能力的用法。can表示能力,意思是"能,会",其否定式can't表示"不能"。在过去时中用could和couldn't。be able to可以表示“能力” 用于各种时态。 4.表“意愿,打算”,常用词为will, would, shall, should.在这里,would,should要比will,shall更委婉,更客气。need表“需要”;dare表示“敢”。 5.表示“请求,许可”,常用词为can, could, will, would, shall, should, may, might, must。 6.态度。may ,can,could,shall, should, may, might, must, ought to用于表示“禁止”,“不准”;“应该”、“必须”“可以”。例如:might可以表示委婉的批评或责备。You might at least have answered my letter. 你至少可以回我一封信吗。 7.祝愿“.May you + 动词原形 ...”,意为“祝愿……”。如:May you succeed! 祝你成功! 8.情态动词与虚拟语气.常见于should+动词原形;情态动词+have 过去分词。 备注:Should 在虚拟语气中要省略,为情态动词要保持。 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”。例如:You may come anytime you want.你想什么时候来都行。 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”。例如:He must be listening to the radio now.他一定正在听收音机。 3、对过去情况的推测,用“情态动词+have+过去分词”。例如:Can he have gotten the book?难道他找到书了吗?

    情态动词用法

    情态动词用法有:情态动词+do/be、情态动词+be doing、情态动词+have done、情态动词+have been doing。 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 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。 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,had better. 对现在或将来的情况进行猜测——情态动词+do/be 。 略举两例: 1、He may/ might come tomorrow.他明天可能会来。(将来) 2、He may/ might know it.他可能知道这件事。(现在) 对现在或将来正在进行的情况进行猜测——情态动词+be doing 略举两例: 1、He may/ might be waiting for you now.他可能正在等你。(现在进行) 2、He may/ might be waiting for you when you get there tomorrow.明天你到那里时,他可能会在等着你。(将来进行) 对过去或已发生的情况进行猜测——情态动词+have done的形式 略举两例: 1、He may/ might have arrived in Beijing by now。他现在估计已经到北京了!(已发生) 2、He must have finished his homework。他一定已经完成作业了!(过去已发生) 对过去进行或现在完成进行的情况进行猜测——情态动词+have been doing 略举一例: 1、He might have been waiting for you when you phoned him.你给他打电话时,他可能已在等你了。(过去完成进行)

    情态动词的用法有哪些?

    情态动词 (Model Verbs) 又称为情态助动词 (Model Auxil-iaries), 主要有can, may, must, could, might, shall , should, will, would, ought to, need, dare等。情态动词与其他动词连用表示说话人的语气。情态动词可表达建议、要求、可能和意愿等。情态动词没有人称和数的变化。情态动词部分重点测试以下内容: (1)情态动词+动词完成式: must have done (2)情态动词+动词进行式: must be doing (3)情态动词+动词完成进行式: must have been doing (4)某些情态动词的特殊用法: need 一、情态动词+动词完成式 情态动词+动词完成式即“情态动词+ have + done分词”,表示对过去行为或动作进行推测、评论或判断。 1. must have done must have done 表示对过去某事的肯定猜测。其否定或疑问形式都用can(could) 来表示. 例如: Since the road is wet, it must have rained last night. He can’t have missed the way. I drew him a map. “The dictionary has disappeared. Who could have taken it?” 当然对现在发生或将来发生的事情,要用must do 表示猜测, 否定为can’t do. He must understand that we mean business. You must be hungry after a long walk. 2.may / might have done may / might have done 表示推测过去某事“也许”发生了.may 比 might 表示的可能性在说话人看来稍大些。例如: I can’t find my keys. I may / might have left them at the school yesterday. 3. could have done 在肯定句型中, 往往用作委婉的批评. 本应该做什么,而没做; 有时也用作猜测. You could have told us earlier. Tom could have taken the dictionary. 4. ought to / should have done和 ought not to / shouldn’t have done ought to / should have done 和 ought not to / shouldn’t have done 用于对已发生的情况表示“责备”、“不满”,分别表示“本应该…”和“本不应该…”。例如: 1)With all the work finished, I should have gone to the party last night. 2)You ought not to have made fun of him. He is not the one you laugh at but learn from. 5. needn’t have done needn’t have done 表示过去做了某事,但没有做的必要, 意为“本没必要…”。例如: You needn’t have waken me up; I don’t have to go to work today. 注:表示推测过去某动作发生的可能性时,就表示的可能性程度而言,must最大,could其次,may更次之,might最小。例如: “I wonder how Tom knew about your past.” “He must / could / may / might have heard of it from Mary.” 二、情态动词+动词进行式 情态动词+行为动词进行式(即情态动词+ be + doing形式),表示推测或评论某动作现在是否正在进行。例如: 1)He must be playing basketball in the room. 2)She may be staying at home. 三、情态动词+动词完成进行式 情态动词+行为动词完成进行式(即情态动词+ have been + v-ing 形式),表示推测或评论过去某动作是否正在进行或一直在进行。例如: 1)They should have been meeting to discuss the problem. 2)He may / might have been buying stamps in the post office when you saw him. 四、某些情态动词的特殊用法 1. need 考试中主要测试 need 作情态动词与作实义动词的区别。情态动词need与实义动词need 在时态、肯定、否定结构上的对比见下表。 时态 情态动词need 实义动词 need 现在时 He need (needn’t) do Need he do….? He needs (doesn’t need) to do 过去时 He needed (didn’t need) to do 将来时 He need (needn’t) do Need he do….? He will (not) need to do 注: need 一般用于否定句或疑问句. 2. dare 考试中主要测试dare作情态动词和作实义动词的区别。 情态动词dare 与实义动词dare 在时态、肯定、否定、疑问结构上的对比见下 表。 句型 情态动词dare 实义动词 dare 肯定句 现在时 dare to 少用 过去时 dare to 少用 现在时 dare/dares to do 过去时 dared to do 否定句 现在时 daren’t/dare not do 过去时 dared not do 现在时 do/does not dare (to) do 过去时 did not dare (to) do 疑问句 现在时 Dare he do? 过去时 Dared he do? 现在时 Do you/Does he dear (to) do? 过去时 Did he dare (to) do 3. can 和 may 考试中主要测试can,may或could,might表示可能性的区别及对may构成的疑 问句的回答。 (1)can, could, may, might都可以表示可能性.can, could表示潜在的可能性或理论上或逻辑判断上存在的可能性;而may, might则表示事实上的可能性。此外,can还具有“有能力”的意思,而may与might则不具此意。例如: According to the weather forecast, it may rain tomorrow. Any man with a little sense can see that he is wrong. (2)May I / we …?这一类疑问句的肯定回答为Yes, please.或Certainly;否定回答为Please don’t.或No, you mustn’t. 例如: “May we leave now?” “No, you mustn’t. You haven’t finished your home work yet.” 4. can 和 be able to can 与 be able to 都可以表示能力,但两者在用法上有点差异:can (could)表示主观能力,不表示意愿,它的将来时用will be able to; be able to表示主观意愿,强调要克服困难去做某事。例如: 1)My grandma is over seventy, but she can still read without glasses. 5. must 和 have to must 和 have to 都可以表示“必须”,但有几点区别: (1)must 强调“内在的职责”、“义务”,而have to 强调“外界压力”、“不得已而为之”。 (2)have to可用于多种时态,而must一般用于现在时,其过去时与将来时分别由had to与shall / will have to代替。 (3)在回答must引起的问题时,如果是否定的答复,不能用mustn’t,而要用needn’t或don’t have to,因为mustn’t是“一定不要”、“一定不能”的意思。例如: You must come to the classroom before eight. 2)It is raining hard outside, but I have to leave now. 3)“Must we do it now?” “No, you needn’t.” 6. used to +do, be used to +doing和be used to +do (1)used to +v意为“过去常常”,“过去一直”;be used to +v-ing / n(名词)意为“习惯于”;be used to +v意为“被用来(做某事)”。 (2)used to只表示过去,而be used to +v-ing / n可表示现在、过去或将来。例如: 1)He used to smoke. Now he doesn’t. 2)He’s quite used to hard work / working hard. 3)The knife is used to cut bread. 7.用作情态动词的其他短语 would rather, would sooner, would (just) as soon, had rather, had better, had sooner, can not but, may (just) as well等可用作情态动词。例如: 1)The soldier would sooner die than surrender. 2)The brave soldier would as soon die as yield to such an enemy. 3)I’d rather walk than take a bus. 4)If you don’t like to swim, you may just as well stay at home. 注:这些短语后一般直接跟动词原形.would (had) rather, would (had) sooner, would (just) as soon后可跟that 引导的从句,that 常省去,从句要用虚拟语气。对现在和将来的假设用过去时,对过去的假设用过去完成时。例如: 1)I would rather you came on Sunday. 2)I would sooner you hadn’t asked

    1、情态动词的用法口诀:情态动词两要点,动词原形跟后边,说话语气较委婉。can表“能力”,may“许可”,must“责任”或“义务”。否定答语needn’t换,“需要”need, dare“敢”,should“应该”,would“愿”,have to“被迫”表客观。 2、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)。 3、用法是:情态动词+行为动词原形。 4、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。 5、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,had better. 6、情态动词还有一个很重要的用法,即情态动词表推测。
