情态动词教案小学篇一

【考纲解读】

情态动词与虚拟语气有千丝万缕的联系，它们往往放在一起考查。

在近年高考题中，对情态动词的考查几乎每年都有纵观近几年的高考题可以看出，高考对情态动词的考查热点依次是：（1）推测和可能性；（2）“情态动词+have done”结构表示猜测或表示虚拟语气；（3）shall, should, can, must表示特定语气。

尤其是对“情态动词+have done”结构的考查频率较高。

试题的情景设置往往生动、真实，但考查的角度趋于细微化和综合化，有效信息较为隐蔽，这就决定了情态动词题是难题之一。

情态动词题每年都考，所以本专题在高考中的重要地位是显而易见的。

因而在复习中应引起高度重视，且依笔者之见，来年高考中对情态动词考查的可能性依然非常大。

【知识要点。

一、情态动词的语法特征

1.情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。2.情态动词 除ought 和have 外，后面只能接不带to 的不定式。3.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。4.情态动词没有非谓语形式，即没有不定式，分词等形式。

二、情态动词的基本用法 1.比较can 和be able to 1)can could 表示能力；可能(过去时用could)，只用于现在时和过去时(could)。be able to可以用于各种时态。

they will be able to tell you the news soon.他很快就能告诉你消息了。2)只用be able to中情况： 位于助动词后； 情态动词后；

表示过去某时刻动作时； 用于句首表示条件；

表示成功地做了某事时，只能用was/were able to，不能用could。he was able to flee europe before the war broke out.=he managed to flee europe before the war broke out.战争爆发前，他就逃离欧洲了。

注意：could，在否定，疑问句中表示推测或怀疑。表示提出委婉的请求（注意在回答中不可用could）。

—could i have the television on? —yes，you can./no，you can’ couldn’t be a bad man.他不大可能是坏人。2.比较may和might

1)表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。may god bless you!愿上帝保佑你！he might be at home.他有可能在家。

注意：might 表示推测时，不表示时态。只是可能性比may 小。

2)may/might as well，后面接不带to 的不定式，意为“不妨，还是……好”。you may(might)as well tell me the truth.你还是对我说实话好。3.比较have to和must

1)两词都是“必须”的意思，have to 表示客观的需要，must 表示说话人主观上的看法，即主观上的必要。

my brother was very ill，so i had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事)

he said that they must work hard.他说他们必须努力工作。（主观上要做这件事）

2)have to有人称、数、时态的变化，而must只有一种形式。

he had to look after his sister yesterday.昨天他不得不照看他的妹妹。3)在否定结构中：

don’t have to 表示“不必”（可以不可以都行）；mustn’t表示“禁止” you don’t have to tell him about it.你不必把此事告诉他。you mustn’t tell him about it.你一定不要把这件事告诉他。表示推测

1)must用在肯定句中表示较有把握的推测，意为“一定”。

2)must表对现在的状态或现在正发生的事情的推测时，must 后面通常接系动词be 的原形或行为动词的进行式。

you have worked hard all must be tired.你辛苦干一整天，一定累了。（对现在情况的推测判断）he must be working in his office.他一定在办公室工作呢。比较：he must be staying there.他现在肯定在那里。he must stay there.他必须待在那里。

3)must 表示对已发生的事情的推测时，must 要接完成式。i didn’t hear the phone.i must have been asleep.我刚才没有听到电话，我想必是睡着了。

4)must表示对过去某时正发生的事情的推测，must 后面要接不定式的完成进行式。—why didn’t you answer my phone call?

—well，i must have been sleeping，so i didn’t hear it.5)否定推测用can’t。

if tom didn’t leave here until five o’clock，he can’t be home yet.如果汤姆五点才离开这儿，他此时一定还未到家。5.表示推测的用法

can，could，may，might，must 皆可表示推测，其用法如下： 1)情态动词+动词原形

表示对现在或将来的情况的推测，此时动词通常为系动词。i don’t know where she is，she may be in wuhan.我不知道她在哪儿，她可能在武汉。2)情态动词+动词现在进行时

表示对现在或将来正在进行的情况进行推测。

at this moment，our teacher must be correcting our exam papers.这时，我们老师想必在批改试卷。

3)情态动词+动词完成时表示对过去情况的推测。

we would have finished this work by the end of next december.明年12月底前我们很可能已完成这项工作了。the road is must have rained last night.地是湿的，昨天晚上一定下雨了。

4)情态动词+动词的现在完成进行时表示对过去正在发生事情的推测。your mother must have been looking for you.你妈妈一定一直在找你。

5)推测的否定形式，疑问形式用can’t，couldn’t表示。

mike can’t have found his car，for he came to work by bus this morning.迈克一定还没有找回他的车，因为早上他是坐公共汽车来上班的。

注意：could，might表示推测时不表示时态，其推测的程度不如can，may。6.情态动词+have+过去分词

1)may(might)have+done (could)have+done sth.表示过去，推测过去时间里可能发生的事情。

philip may(might)have been hurt seriously in the car accident.飞利浦在那场车祸中有可能伤的很严重。

2)must have+done sth.对过去时间里可能发生的事情的推测，语气较强，具有“肯定”“谅必”的意思。

—linda has gone to work，but her bicycle is still here.—she must have gone by bus.3)ought to have done sth.／should have done sth.本应该做某事，而事实上并没有做。否定句表示“不该做某事而做了”。

he ought not to have thrown the old clothes away.（事实上已扔了。）ought to 在语气上比should 要强。4)needn’t have done sth.本没必要做某事 i dressed very warmly for the trip，but i needn’t have done weather was hot.那次旅行，我穿的非常暖和，但我本没有必要那么去做。天太热了。5)would like to have done sth.本打算做某事

i would like to have read the article，but i was very busy then.我本想读那本书，但我那时太忙了。 和ought to

should 和ought to 都为“应该”的意思，可用于各种人称。—ought he to go?

—yes.i think he ought to.表示要求，命令时，语气由 should（应该），had better最好），must（必须）渐强。 better表示“最好”

had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。had better do sth.最好干某事

had better not do sth.最好不干某事

had better have done sth.表示与事实相反的结果，意为“本来最好”。 rather表示“宁愿” would rather do 宁可干某事

would rather not do 宁可不干某事 would rather...than...宁愿……而不愿

还有would sooner，had rather，had sooner都表示“宁愿”“宁可”的意思。i would rather stay here than go home.=i would stay here rather than go home.我宁可待在这儿也不回家。

和would

1)would like；would like to do=want to 想要，为固定搭配。would you like to go with me?你想和我一块儿去吗？

2)will you...? would you like...?表示肯定含义的请求劝说时，疑问句 中一般用some，而不是any。

would you like some cake?要蛋糕吗？

3)否定结构中用will，一般不用would，won’t you是一种委婉语气。won’t you sit down?你不坐吗? 11.情态动词的回答方式

must和need相同:yes,...,...needn't/don't have to may和can could相同:yes,...may/can/,...mustn't/...'d better not/can':yes,...can/,...can':yes,...,...shouldn'和would差不多:yes,...do/,...won't/thanks.典型例题

1）---could i borrow your dictionary?---yes,of course, 表示委婉的语气,并不为时态.答语中of course,表示肯定的语气,允许某人做某事时,用can和 may来表达,不能用could或might.复习：will 与you连用,与you 连用,用来提出劝告.2）---shall i tell john about it?---no,you ___.i've told him 't 't 't n't 't 不必,'t 将不,mustn't 禁止、n't 不应该.本题为不需要,不必的意思,应用needn't.3）---don't forget to come to my birthday party tomorrow.---______.a.i don't b.i won't c.i can't d.i haven't 答案既可当作情态动词,表请求、建议、也可作为实义动词表“意愿、意志、决心”,本题表示决心,选b.12.比较need和dar。

一、need表示“需要”或“必须”，作情态动词时，仅用于否定句或疑问句中，在肯定句中一般用must,have to,ought to，或should代替。 i attend the meeting tomorrow?

我需要明天参加会议吗? need not hand in the paper this week.这一周你不必交论文。

need 是一个情态动词，他的用法完全和其他情态动词一样，但 need 还可当作实义动词使用，这时 need 就象其他动词一样，有第三人称，单复数，后面加带 to 的动词等特性。1.i need a bike to go to school.我上学需要一辆自行车。 you need a dictionary? 你需要词典吗? needs a necklace.她需要一条项链。

needn't + have + 过去分词 表示过去做了没必要做的事情。you needn't have taken it seriously.这件事情你不必太认真。

二、dare表示“敢”，dare作情态动词时，主要用于疑问句、否定句和条件从句中，一般不用在肯定句中。多用在否定或疑问句中。 little girl dare not speak in public.小女孩不敢在公众面前说话。 you catch the little cat? 你敢抓小猫吗? dare 除用作情态动词外，更多的是当实义动词使用，用法同实义动词一样，要考虑人称，单复数，时态等。

you dare to walk in the dark? 你敢黑夜走路吗？

doesn't dare to tell the teacher what happened that day.他不敢告诉老师那天发生的事。

三、dare和need常用作实义动词，有时态、人称和数的变化，所不同的是，作实义动词时，在肯定句中，dare后面通常接带to的不定式，在否定和疑问句中，dare后面可接带to或不带to的不定式。如：

i dare to swim across this does not dare(to)'t you dare(to)touch it!i wondered he dare(to)say tha needs to finish it this evening.另外need 的被动含义：need，want，require，worth（形容词）后面接doing，也 可以表示被动：need doing=need to be done shall用于第一人称,表示征求对方的意愿.如：what shall we do this evening? 用于第一、第三人称疑问句中,表示说话人征求对方的意见或向对方请示.如：shall we begin our lesson? when shall he be able to leave the hospital? 用于第二、第三人称,表示说话人给对方命令、警告、允诺或威胁.如：you shall fail if you don't work harder.（警告）he shall have the book when i finish reading.（允诺）he shall be punished.（威胁。

五、情态动词的解题例析

(1)认真审题，结合所给出的语境，正确把握说话者的语气、情感、态度、观点等。

(2)认真思考所给选项中情态动词的基本特征和用法，并结合语境推敲答案。(3)要注意把握时间概念。

情态动词无论是表达“推测和可能性”，还是表达“虚拟”这一概念，只要是对过去已经发生的事情进行描述，一律用“情态动词+have done”这一结构；对现在或将来的事情进行描述，用“情态动词+动词或系动词原形”。例如：

（nmet2008山东，24）thank you for all your hard work last week.i don’t think we ______ it without manage

have managed manage have managed 根据题干中所给出的时间last week可知我们已经做完了工作，已经完成，故排除a、c两项，再结合could have done表示虚拟语气以及与前面的i don’t think…，故说话者想表达的意思是：离开了你，我们本不可能完成这项工作。故答案为b项。

expansion and improvement【知识拓展、能力提升】（d级 拓展类）（c、b层学生展示，a层学生补充）

★下面我们来看看常考的一些情态动词★

以下试题均来源于往年的高考试题，具有很强的针对性

(1)must表示推测，意为“一定„„”，只能用于肯定句中。must have done意为：一定做过某事或某事肯定发生了。例如：

—she looks very ______ have passed the exam.—i guess ’s not difficult after

【解析】句意为：她看上去很高兴，一定是通过了考试。【答案】c(2)should(not)/ ought(not)to在中表示根据常规或常识推测，表示“某事应该或不应该发生”，语气比must或can’t / couldn’t稍弱。例如：—how’s your tour around the north lake? is it beautiful? —it ________ be, but it is now heavily polluted.

【解析】should此处表示推测，意为“应该”。【答案】c ②there _________ be any difficulty about passing the road test since you have practiced a lot in the driving ’t

’t

n’t

’t 【解析】句意：既然你在驾校进行了大量训练，那么通过道路测试按理不应该有困难。【答案】c(3)can, could表达推测时，一般用于疑问句和否定句中；can用于肯定句中表示一种理论上的可能性，并不牵涉是否真的会发生，在这种用法中can只能与动词原形连用；could用于肯定句中，语气比may/ might更弱。例如： ①you ______ be hungry already — you had lunch only two hours ago!

’t

’t

’t

’t ②she ______ have left school, for her bike is still here.’t

n’t

n’t

’t ③it is usually warm in my hometown in march, but it _____ be rather cold

④peter ____ be really difficult at times even though he’s a nice person in

【解析】①② 两个考题中can用于中表示否定的推测，意为：不可能，一定不会； ③④两个考题中can表示理论上的可能性，翻译为：有时候会„„。【答案】① b ② a

③ b ④ c(4)may(not)/ might(not)表达一种不太把握的推测，意为“或许，可能”；might的语气比may较婉转。例如：

① liza ___ well not want to go on the trip---she hates

【解析】may well为固定搭配，意为：很可能，极有可能。【答案】ｄ

②

although this ____ sound like a simple task, great care is

【解析】这听起来或许是一项简单的任务，但却需要极大的细心。【答案】b ③—i can’t find my purse anywhere.—you __ have lost it while

【解析】结合语境可知，回答者是在提醒对方：或许购物时把钱包丢了。【答案】a

（二）表达虚拟语气的情态动词

对过去的一种结果的假设或虚拟，用情态动词+have done这一结构，常用的有以下几个情态动词：

(1)should(not)/ ought(not)to have done本（不）应该做某事，但却没有做或做了，含有责备或后悔之意。例如：

—i’m sorry.i _________at you the other day.—forget it.i was a bit out of control n’t shout

n’t have shouted ’t shout

’t have shouted 【解析】对不起，我那天本不应该对你大喊大叫的。【答案】b(2)could have done本来能够做某事但未做。例如：

thank you for all your hard work last week.i don’t think we ______ it without manage

have managed manage

have managed 【解析】根据题干中所给出的时间last week可知我们已经做完了工作，已经完成，故排除a、c两项，再结合could have done表示虚拟语气以及与前面的i don’t think„，故说话者想表达的意思是：离开了你，我们本不可能完成这项工作。

【答案】b(3)needn’t have done本没有必要做某事但却做了。

要注意needn’t do则表达“没有必要去做某事”，时间上应该是现在或将来。

例如： ①—catherine, i have cleaned the room for you.— ________ it.i could manage it ’t d。

n’t have done

’t do

n’t have done 【解析】根据句意可知catherine对对方为她打扫了房间表示感谢并提到对方不必为她打扫房间。【答案】b ② the boss has given everyone a special holiday, so we

go to work ’t

n’t

n’t

n’t 【解析】老板给所有的员工放了假，所以我们明天不必再去上班。【答案】c(4)would(not)have done本来(不)会发生某事，但却（发生了）或没有发生。常用于虚拟条件句或含蓄虚拟条件引导的虚拟语气，表示对过去所发生事情结果的假设。例如：

he hesitated for a moment before kicking the ball, otherwise, he ________ a scored

score

have scored 【解析】句中otherwise为含蓄条件，相当于if he had not hesitated for a moment before kicking the ball，这是对过去的一种虚拟假设。【答案】d(5)might have done表示“本来可能„„”，但实际上没有发生的事。例如： what a pity!considering his ability and experience, he ________ have done

have done have done

have done 【解析】真是可惜！考虑到他的能力和经验，他本来可以做得更好的。【答案】d

（三）表达“情感、态度、语气” 等方面的情态动词 表达“情感、态度、语气”主要有以下用法：

(1)表示主观的义务和必要，主要用于肯定句和疑问句，意思为“必须„„，得„„，要„„”；由must引起的疑问句，肯定回答要用must或have to，否定回答要用needn’t或don’t have to,意思是“不必”。另外，must与have to都可以表示“必须”这一含义。must表示一种主观的需要，而have to表示一种客观的需要，意思是“不得不”，其否定形式是don’ have to。例如：-what sort of house do you want to have? something big?--well, it ______ be big--that's not 't

n't

't

't

【解析】something big?此处意为：must it be big? 回答者的意思是：房子不必太大—那并不重要。

【答案】b

(2)must的否定形式mustn’t表示禁止，意思是“不能，不许”。例如： when i was young, i was told that i ______ play with matches

't

n't

't

't 【解析】当我年轻的时候，（家人）就一直告诫我千万不要玩火柴。【答案】c(3)must用于条件句或疑问句中，可以用来表示责备、抱怨的感情色彩，意思为“偏要，硬要、干嘛”。例如： ①—may i smoke here ? —if you ____, choose a seat in the smoking

②john, look at the time.___________ you play the piano at such a late hour? a．must

b．can

c．may

d．need 【解析】must在这两道试题中均表示“非得，偏要”。【答案】① d

② a (1)should应该，表示“责任和义务”。例如：

according to the air traffic rules, you ___ switch off your mobile phone before

【解析】should此处表示根据交通法规应尽的责任和义务。【答案】d(2)在虚拟条件句中用以加强假设语气，表示“与将来事实相反的假设”，用 if+主语+ should +动词原形，当“万一(会)”讲。这时可省略if，将should提到句首，变为倒装句式。请看下面的例子：

if it should rain(=should it rain)tomorrow, i would stay at home.万一明天下雨的话，我就待在家里。再如：

________ fired, your health care and other benefits will not be immediately cut you be

you be

you be

you be 【解析】句意：万一你被解雇，给你的医疗救助和其它方面的福利也不会被取消。【答案】b(3)should还可以用来表示说话人对某事不能理解、赶到意外、惊异等意思，译为“竟然，竟会”。例如：

you can’t imagine that a well-behaved gentleman _____ be so rude to a

【解析】句意：你想象不到这么一个表现良好的绅士竟然会对一个女士这么粗鲁。【答案】c (1)shall用于第一和第三人称，常用于疑问句中，用来征求对方意见。例如： ①—what’s the name? —khulaifi._________ i spell it for you?

【答案】a

(2)用于第二和第三人称，表示“命令、威胁、警告、允诺、”等。例如： —excuse i want to use your computer to type a report.—you _____have my computer if you don’t take care of ’t

not

n’t

n’t 【解析】shall此处表示“警告”。【答案】a(3)shall也用于宣布法律、规定的要求。例如： ①—what does the sign over there read? —“no person ________ smoke or carry a lighted cigarette，cigar or pipe in this area.”

【解析】禁止吸烟是此处的规定。【答案】c (1)can可以用来表示惊异、怀疑、不相信的态度，主要用于否定句、疑问句或感叹句中。例如：

how ______ you say that you really understand the whole story if you have only covered only part of the article?

【答案】a(2)can也可以用来表示请求或许可。例如： —mum, i’ve been studying english since 8 o’clock.______i go out and play with tom for a while? —no, i’m afraid s, it’s raining outside ’t

n’t

’t 【答案】a(3)can可以表达一般的或永久的能力。be able to也可表达能力，但常用来表达在某件事情中所表现出来的能力，尤指克服困难能够完成某事。例如： ①

if it were not for the fact that she ______ sing, i would invite her to the ’t

n’t

’t

not ②

the fire spread through the hotel very quickly but everyone ______ get to

able to 【答案】c (1)will与would可表示“意愿；意志 ”。

例如： john promised his doctor he _____ not smoke and he has never smoked ever

【解析】根据promise可知此处是john向医生表明自己的意志。【答案】d(2)would表示过去倾向性或习惯性的动作。used to 也有这一用法，但used to即可用来表达过去的习惯性的动作，也可用来表示过去的状态。例如：

① when he was there, he ___ go to that coffee shop at the corner after work every

better

② in my opinion, life in the twenty-first century is much easier than used to be

is used to

was used to

used to be 【解析】第一题would指过去习惯性的动作；第二题it 替代life, used to be 指过去的样子。【答案】a d
