情态动词should/ought to的用法距离高考还有一段时间,不少有经验的老师都会提醒考生,愈是临近高考,能否咬紧牙关、学会自我调节,态度是否主动积极,安排是否科学合理,能不能保持良好的心态、以饱满的情绪迎接挑战,其效果往往大不一样。
以下是本人从事10多年教学经验总结出的以下学习资料,希望可以帮助大家提高答题的正确率,希望对你有所帮助,有志者事竟成!养成良好的答题习惯,是决定高考英语成败的决定性因素之一。
做题前,要认真阅读题目要求、题干和选项,并对答案内容作出合理预测;答题时,切忌跟着感觉走,最好按照题目序号来做,不会的或存在疑问的,要做好标记,要善于发现,找到题目的题眼所在,规范答题,书写工整;答题完毕时,要认真检查,查漏补缺,纠正错误。
总之,在最后的复习阶段,学生们不要加大练习量。
在这个时候,学生要尽快找到适合自己的答题方式,最重要的是以平常心去面对考试。
英语最后的复习要树立信心,考试的时候遇到难题要想“别人也难”,遇到容易的则要想“细心审题”。
越到最后,考生越要回归基础,单词最好再梳理一遍,这样有利于提高阅读理解的效率。

☞重/难点重点:情态动词should/ought to的基本用法。
难点:在语言实践中正确运用情态动词should/ought to的用法。
☤重/难点分析重点分析:情态动词should可以译为“应该”,表示责任和义务以及主观上合乎逻辑的推测;也可以表示“居然,竟然”。
should可以用于倒装,置于主语前面而省略if。
在表示命令、请求、建议、要求、推荐等动词后的宾语从句中,谓语动词用“(should)+动词原形”,should可以省略。
在句型“It’s + adj.+ that…”中,that从句中常常用“should+动词原形”。
表示“本该做而未做”用should have done;表示“本不该做而做了”用shouldn’t have done。
7B Unit 6 Grammar-----情态动词(2) should/ /must一、should 和ought toshould在1. should 情态动词:应该(侧重于人的主观看法) (从形式上来看should 是shall的过去式)否定句形式:should not = shouldn’t 不该疑问句形式:将should提前。
[根据课本:我们用要should 和should not向别人提出建议,告诉别人最好做哪些事或做哪些事是正确的,此时与ought to和ought not to 有类似的含义,可以互换]①Y ou should be more careful next time.②We should help each other.③Should we look after him ?④Y ou shouldn’t be so careless.⑤What should we do next?二、must的用法(含have to用法)1. must 表示必须、必要。
如:Y ou must come to school on time. 你必须按时来上学。
★★★回答must引出的问句时,如果是否定的回答,不能用mustn’t,而要用needn’t或don’t have to。
例:—Must we finish our homework now ?—Y es, you must. (No, you needn’t.= No, you don’t have to. )[根据课本:我们用must告诉别人某事是必需的或是非常重要的,我们用mustn’t告诉别人不去做某事是必需的或是重要的]2. have to(不得不,必须)的含义与must相似,两者往往可以互换使用,但must与have to有下列几点不同:①must have tomust go now.I have to stay in bed because I am ill.②must只有一种形式,have则涉及人称、时态等方面的变化形式。

There are three questions for the student to summarize the structure of should/ ought to + Vo (the verbs do not change their form after modal verbs ) as follows:●When do we use ‘should’ or ‘ought to’?●How to use them?●What’s the difference between ‘should’ and ‘ought to’?2. Tell the student the answers for the third question which is we can use the modal verbs should andought to to say what is best or right to do. Should and ought to are similar in meaning. But the voice of ought to is stronger than should with the meaning of doing something for responsibility or obligation.3.

ought,should,must,have to,need的区别ought的各种形式ought是情态动词。
ought没有其他形式,可用于现在时以及将来时。
用于过去时则位于动词过去式之后或不定式的完成式之前:I ought to write to him today/tomorrow.我今天/明天应该给他写封信。
I knew I ought to write to him.我那时知道我应该给他写封信。
She said I ought to write.她说我应该写。
I know/knew that I ought to have written.我知道/那时知道我该写的。
否定式:ought not/oughtn't疑问式:ought I?等否定疑问式:ought I not?/oughtn't I?等ought与带to的不定式连用。
为了提醒学生这一点,常称之为ought to。
问句或话语中用ought to的时候,可以用should来回答;用should的问句或话语也可以用ought to回答:—You ought to put in central heating.—Yes,I suppose I should.—你应该装上暖气。
—是的,我应该装。
should的各种形式should也是情态动词。
与ought的各种形式相同,should可用于现在时以及将来时。
如位于动词过去式之后时,也可以用于过去时。
在上文的各例句中should可代替ought to使用。
否定式:should not/shouldn't疑问式:should I?等否定疑问式:should I not?/shouldn't I?等should后面带没有to的不定式(即动词原形)。
should和ought用于表示义务时通常意思是同样的,但should 是较为常用的形式。
在会话中should/ought to常可单独使用,此时动词不定式省略而不说出:—You should paint/ought to paint your door.—Yes,I know I should/I know I ought to.—你应当油漆—下你的门。
should和ought to的区别should和ought to是两个常见的词汇,经常在英语中被使用。
尽管它们有类似的意义,但在使用和语气上有一些微妙的区别。
should的使用::- should常用于表示建议、倡导或期望行为的情况。
- should通常用于一般情况下的建议,表示某种行为是明智、正确或有益的选择。
- should语气较轻松,有时有一点不确定或是可选的意味。
例如:- You should eat more fruits and vegetables.(你应该多吃水果和蔬菜。
)- You should watch this movie, it's really good.(你应该看这部电影,它非常好。
)- I should go to bed early tonight.(我今晚应该早点睡觉。
)ought to的使用::- ought to也表示建议或期望行为,但它通常带有更强烈的道德义务或责任感。
- ought to强调的是应该采取某种行动,因为这是一个责任、义务或是基于道德判断的选择。
- ought to语气更加坚定,表达的是强烈认为某种行为应该被执行。
例如:- You ought to apologize for what you said.(你应该为你所说的道歉。
)- We ought to help those in need.(我们应该帮助那些需要帮助的人。
)- She ought to study harder for the exam.(她应该更努力地研究考试。
)总结起来,should和ought to都表示建议和期望,但ought to 更加强调道义和责任感。
在实际使用中,根据语境和所表达的意义来选择合适的词汇会更加准确。
should和ought to在使用上有一些微妙的区别:- should常用于一般的建议,语气较轻松,有时不确定或可选。
- ought to强调的是应该采取某种行动,带有较强的道义义务感。
should和ought to的用法Should和Ought to的用法Should和Ought to是英语中两个常用的情态动词,它们在表达建议、劝告、责任等方面都有着重要的作用。
本文将详细介绍这两个情态动词的用法。
一、Should的用法1. 表示建议或劝告当我们想要给别人提出建议或劝告时,可以使用should来表达。
例如:- You should go to the doctor if you're feeling unwell.(如果你感觉不舒服,你应该去看医生。
)- You should study hard if you want to pass the exam.(如果你想通过考试,你应该努力学习。
)2. 表示推测或猜测有时候我们需要根据已知信息进行推测或猜测,这时可以使用should来表示。
例如:- It should be sunny tomorrow.(明天应该是晴天。
)- He should have arrived by now.(他现在应该已经到达了。

)4. 表示建议性的命令有时候我们需要给别人下达命令,但又不想显得太强硬,这时可以使用should来表示。

had better 也可改为 had best ,其意义和用法不变。

三 . 掌握句型变换方法had better, should, ought to 均属于助动词,其疑问句、否定句及反意疑问句的构成均在自身形式上做变化。
1. 变成否定句方法had better do 否定式为 had better not do, should do 否定式为 should not do 或shouldn't do, ought to do 否定式为 ought not to do 或 oughtn't to do 。
2. 变成一般疑问句方法had better, should, ought to 构成一般疑问句时应分别将 had, should, ought 提到句首,其肯定与否定回答为 had / hadn't, should / shouldn't, ought / oughtn't 。

表示“应该”和“必须”的情态助动词should, ought to, have to 与must(1)表示不可逃避的义务或表示“必须”的must。
must通常只用于现在时和将来时,其他时态则用have to代替。
have to比must往往更强调客观的要求或外在的原因:In the play, she must appear in a bright red dress and long black stockings.演出时她必须穿一条鲜红色的裙子和黑色的长筒袜。
Last year in another play, she had to wear short socks and a bright, orange-coloured dress.去年在演另一个剧时,她不得不穿短袜和一件鲜艳的橘红色的衣服。
(2)should 和ought to都可译为“应该”,表示义务、责任或某个正确的行为。
ought to 比should语气略强些,多用于肯定句;疑问句与否定结构则多用should。
与它们相比,must 和have to 的语气要强得多,没有选择余地:must和have to表示“必须”,而should和ought to表示“责任”、“义务”或是“一个正确的行动”。
试比较:I can’t go to the cinema tonight; I must (or have to) write some letters.今晚我不能去看电影,我必须写几封信。
(我没有选择,我必须而且将会写这些信。
)I should (or ought to) do some work tonight, but I think I shall go to the cinema instead.今晚我应当做一些工作,不过我想我会去看电影的。
(对我来说,正确的做法是工作,但是我选择了去看电影。
)(3)had to表示“过去的必须”,表示过去必须做某事。
情态动词:Should和Ought toought to与should意思接近,大多数情况下二者可以互换,但是should谈的是自己的主观看法,ought to则更多反映客观情况,在谈到法律、义务和规定时使用。
如:I should go and see Mary tomorrow.我明天应该去看看Mary。
She is your mother, so you ought to support her.她是你妈妈,你应该赡养她。
We should/ought to help each other and learn from each other in our work.在工作中我们应该互相帮助互相学习。
ought to :它比must语气弱,但婉转。
They ought to be there by now. 他们现在一定到那了一般用于肯定和否定句ought 与不定式构成谓语动词。
主要用法如下:(1 )表示应该做某事。
例如:You ought to take his advice. 你应当接受他的劝告。
(2 )ought + 不定式的完成形式,表示本应该做某事。
例如:They ought to have handed in the paper yesterday. 他们本应当昨天交论文。
should :表示说话人的猜测,估计应该That should be Janet coming upstairs now. 正在上楼的准是珍妮特。
多用于第一人称。
should :(1) 表示劝告或建议。

(2) 表示预测或可能。
例如:This kind of reference book should be in the reading-room. 像这样的参考书应该放在阅览室。
(3) 表示惊奇、愤怒、失望等感情。
had better, should, ought to用法had better, should, ought to是重要的情态动词,也是高考重要考点,学习时应注意下列几点:一、了解相互间关系had better(最好), should(应该)与ought to(应该)均为提建议、阐述观点的情态动词,其后接动词原形。
should 比had better语气强,ought to语气最强。
一般情况下should与ought to可通用。
例1:You had better go there at once.你最好立即去那里。
例2:You ought to / should work hard.你应该努力工作。
值得注意的是:should还有"竟然"之意,表出乎意料。
例:You can't imagine that a well-behaved gentleman should be so rude to a lady.你真是难以想象这么一个有风度的先生对一个女子是如此之粗鲁。
二、掌握句型变换方法had better, should, ought to作为情态动词,各种句型变换均在自身形式上作变化。
(一)否定句had better, should, ought to用于否定句时,否定词均位于其后,具体形式为:had better not do, shouldn't / should not do, oughtn't to do。
例1:You had better not start at this time.此时你最好别出发。
例2:He shouldn't be careless in class.他上课时不应粗心。
例3:She oughtn't to waste time.她不应该浪费时间。
(二)一般疑问句had better, should, ought to用于一般疑问句时,分别将had, should, ought提至句首。
should和ought to有什么区别呢,大体上两者的意思是相同的,通常可以互相转换。
ought是助动词,不是过去式。
二者区别:ought to比should 语气强(1)should 表示主观看法,一些建议,劝说时,译作“应当”。
ought to,直接接动词原形,更多反映客观情况,“有义务”或“必要”做某事,译为“应当,应该”(2)ought to的否定就表示做某事一定是错误的而should的否定就表示某动作不一定要做3.should可以用于虚拟语态,而ought to 不能ught to 是唯一一个可加to的情态动词!ought to 比should语气更强烈ought to的否定就表示做某事一定是错误的而should的否定就表示某动作不一定要做表示应该,责备时区别不大但是should可以在名词从句中表示虚拟如在suggest,advise,等从句中在lest,for fear that, in case等的状语从句中也只用should 另外should有表示惊讶之意ought to与should意思接近,大多数情况下二者可以互换,但是should谈的是自己的主观看法,ought to则更多反映客观情况,在谈到法律、义务和规定时使用。
如:We should/ought to help each other and learn from each other in our work.She is your mother, so you ought to support her.We ought to go and see Mary tomorrow, but I don’t think we will.、ought to具体用法如下:1. (表示义务、责任等) 应当, 应该You ought to work harder than that.2. (表示劝告、建议等) 应该, 该You don't look well. You ought to go to see the doctor.3. (表示猜测、期望) 总应该,理应It ought to be a fine day tomorrow morning.4. “ought to + have + 过去分词”表示过去应做某事而实际未做You ought to have told me that (but you didn't).这时ought to和should可以互换使用。

a lot of、lots of、a number of( /large numbers of)、a great deal of、plenty of的区别:五个“名词+介词”短语都表示“大量,许多”,a lot of(或lots of)既可以修饰不可数名词也可以修饰可数名词的复数形式,可以相应地换为much和many;plenty of“足够、大量”,既可以修饰不可数名词也可以修饰可数名词的复数形式。
a number of / large numbers of只可以修饰可数名词复数形式(它修饰的词作主语时谓语用复数形式)可以换为some、many、a lot of、plenty of。
a great deal of只可以修饰不可数名词(它修饰的词作主语时谓语用单数形式)可以换为much。
如:A lot of people think that time is money.(许多的人认为时间就是金钱。
)/ I don’t have to do it in a hurry because I have plenty of time.(我用不着赶忙,因为我有充足的时间。
) / I have a number of letters to write today.(今天我有好多信要写) / I spend a great deal of time/money on shopping.(在购物方面我花费了大量的时间/金钱。
)mount用作名词时,意为“数量”“金额”等,通常用于 a (great, large) amount of 这类结构,其后通常接不可数名词。
如:There was a fair amount of traffic on the roads. 路上的车辆颇多。
An increasing amount of organic produce is to be found on supermarket shelves. 越来越多的有机产品出现在超市货架上。
这类结构用作主语,其谓语的数取决于 amount 的数。
如:在这座桥上花了大量资金。
正:A large amount of money was spent on the bridge.正:Large amounts of money were spent on the bridge.注:偶尔也可见到其后接复数可数名词的用法,但不算普通。
如:The shopkeeper had a large amount of oranges in his storeroom. 店主在货仓里存有大量橙子。
——摘自《朗文当代高级英语词典》Even small amounts of these substances are known to cause skin problems. 我们知道这种物质即使是一丁点也会损害皮肤ought的各种形式ought是情态动词。
(参见第107节B。
)ought没有其他形式,可用于现在时以及将来时。
用于过去时则位于动词过去式之后或不定式的完成式之前:I ought to write to him today/tomorrow.否定式:ought not/oughtn´t疑问式:ought I?等否定疑问式:ought I not?/oughtn´t I?等ought与带to的不定式连用。
为了提醒学生这一点,常称之为ought to。
问句或话语中用ought to的时候,可以用should来回答;用should的问句或话语也可以用ought to回答:—You ought to put in central heating.—Yes,I suppose I should.140 should的各种形式should也是情态动词。
与ought的各种形式相同,should可用于现在时以及将来时。
如位于动词过去式之后时,也可以用于过去时。
在上文的各例句中should可代替ought to使用。
否定式:should not/shouldn´t疑问式:should I?等否定疑问式:should I not?/shouldn´t I?等should后面带没有to的不定式(即动词原形)。
should和ought用于表示义务时通常意思是同样的,但should 是较为常用的形式。
在会话中should/ought to常可单独使用,此时动词不定式省略而不说出:—You should paint/ought to paint your door.—Yes,I know I should/I know I ought to.141 ought/should与must和have to的比较A 用法的不同1 ought/should表示主语的义务或责任:You should send in accurate income tax returns.They shouldn´t allow parking here;the street is too narrow.This word is spelt wrongly.There should be another‘s´.这不像must那样牵涉到说话人的权威,也不像have to那样牵涉到外界权威(参见第145节),仅仅牵涉到良心或见识的问题:Pianist to pupil:You must practise at least an hour a day.Pupil to musical friend:I have to practise an hour a day!Musical friend:You ought to/should practise for more than an hour.2 ought/should与must和have to之间的又一区别在于,用must 和have to时通常给人的印象是一种义务正在被履行或将被履行。
主语为第一人称时尤其是这样,而其他人称为主语时也常是这样。
但ought/should则不使人特别感到义务正在或将要被履行。
它时常给人义务不在或不将得到履行的印象,在第一人称主语后更是如此。
如果一位驾驶员说I ought to/should go slowly here;it´s a built-up area(我是该在此慢行的,这是一个建筑物密集的地区),这通常这意味着他不想要放慢车速。
如果他真的要放慢车速,他会说I must go/have to go/I will have to go slowly here。
同样,如果某人说We must have a party to celebrate your engagement(我们必须举办一个聚会来庆祝你的订婚之喜),他的朋友们有相当理由相信会举行聚会的,但如果他说Weshould have a party…就不是非常确定无疑的事了,他说话的语气或表情可能表示不可能举行聚会。
B 用法中类似的地方1 should(但不是ought)可以用于正式通知或书面文告等:Candidates should be prepared to answer questions on…应试者应有准备回答……方面的问题。
Intending travellers should be in possession of the following documents…准备去旅行的人应备有以下的证明文件……On hearing the alarm bell,hotel guests should leave their rooms…听到警报铃声后,饭店的旅客必须离开各自的房间……在这里可以用must而不改变句子的意思,但在此should表示义务的口气更缓和些。
2 ought和should可表示忠告:You ought to/should read this.It´s very good.你应该读一下这个。
它写得很好。
但在语气较重的劝告中用must比较好:You must read this.It´s marvellous!你必须读这个。
写得精彩极了!142 ought/should与进行式连用ought/should与进行式连用时表示主语没有履行其义务,做了愚蠢、鲁莽的事等或做事不明智、不慎重等:He ought to be studying for his exam.He shouldn´t be spending all his time on the beach.他本该正在学习以备考试。
他不该把他的全部时间都在海滩上度过。
We should be wearing seat belts.我们应该系好安全带。
(但我们没有系安全带。
)I shouldn´t be telling you this.It´s supposed to be a secret.我不应该告诉你这件事。
这是个秘密。
143 ought/should与完成式连用这个结构用来表示没有覆行义务或不明智地忽略了该做的事。
在否定式中这一结构表示从前发生的、错误的或愚蠢的事。
You ought to have told him that the paint on that seat was wet.你本应该告诉他椅子上的油漆还没有干。
You should have turned his omelette;he likes it turned.你本应该给他摊的鸡蛋翻个身的;他喜欢吃两面都煎透的摊鸡蛋。
They ought to have stopped at the traffic lights.他们本应在红绿灯处停下。
She shouldn´t have opened the letter;it wasn´t addressed to her.她不应该拆开信,信封上写的不是她的名字。
The Emergency Exit doors shouldn´t have been blocked.紧急出口的门本来不应被堵死。
