高考情态动词常用考点分类讲解(含高考真题及答案讲解)

情态动词

一、概念:

情态动词表示说话人对某一动作或状态的态度。

常见的情态动词有:can、may、must、could、might、should、will、shall、would、ought to、need、dare等以及具有情态动词功能的have to、ought to和had better。

二、特点:

1. 有一定词义,但本身词义不全,不能单独作谓语,后面必须与动词原形一起构成谓语(情态动词必须放在行为动词之前)。

例如:He can play basketball.他会打篮球。

在这个句子中,情态动词仅仅表达“能够”,但未表达出“打”,不能单独充当谓语,必须和“play”一起构成谓语。

2. 情态动词没有人称和数的变化,但有的情态动词有过去式。

例如:(1)I must go now.我必须走了。

(2)He must go now.他必须走了。

(3)She might be doing her homework at that time.那时她也许正在做作业。

在句子(2)中,虽然主语he是第三人称单数,但谓语由情态动词must和行为动词构成,没有人称和数的变化。

在句子(3)中,用at that time表示过去的时间,谓语动词may用其过去式might。

具有过去式的情态动词如下:

can→could may→might will→would shall→should

注意: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。

例如:Would you mind very much if I ask you to do something?(此句中would不表过去)3. 情态动词本身没有分词形式,如果要表达正在进行或已经进行完毕,分词形式要加在情态动词后面的行为动词上。

例如:(1)They must have won the match, for they are so excited now.

他们一定赢了比赛,因为他们现在很兴奋。

(2)They must be discussing something.他们一定正在讨论一些事情。

4. 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。

三、常见考点讲解分析:

考点一can与could

1.表示能力,但could主要指过去的能力(但不一定去做)。表示“过去有能力并成功做成某事”时通常用was/were able to。[来源:学科网]

3.表示请求和允许。在问句中could语气比can要委婉。

2.need作行为动词时,若主语和动作之间存在被动关系,可采用下列两种方式表达:方式一:用动词的主动形式表示被动意义,结构为need(s)+动词ing形式;

方式二:用不定式的被动形式,结构为need(s)+to be+动词过去分词。

考点八情态动词表推测时情态动词的选择

can,may,must皆可用来表示推测。

1. 在肯定句中都可以用来表示可能性。在含义上“must”语气最肯定,“may”表示不太肯定的可能性,而can表示理论上的可能性。

2. 在否定句中只能用“can not”和“may not”。“can't”(不可能)语气比“may not”(可能不、也许不)更强。

在雪下得这样打的天气,容易发生事故。(表理论上的可能性)(2)Look,there is some blood on the road;an accident must have happened just now.

昨晚不可能下过雨,因为路面是干的。

2.may/might have done 表示对过去行为的推测,意为“可能做过”。might 所表示的可能性比较弱,此外might have done 还可表示“本可能做而实际上未做”,含有轻微的责备语气。

例句:(1)You might have given him more help,though you were busy with your work.

虽然你工作很忙,但你本来可以给他更多的帮助的。(实际上没有)(2)He might have been to Beijing. 他或许去过北京了呢。

答案:

2013年

1. 【解析】选B。考查情态动词。句意:根本不可能是词汇造成了你练习中的问题,因为你掌握了许多单词。根据句意可知本题考查的是对现在的否定推测,故选B。may“可能”;should“应该”;needn’t“不需要”。K][来源:Z+xx+https://www.wendangku.net/doc/a311989832.html,]

2.【解析】选B。考查情态动词表示推测。句意:因为没有人帮助他,他一定独自完成了这项研究。can表示推测时,常用于否定句和疑问句,用于肯定句时,表示理论上对客观情况的推测;must表示推测时,只能用于肯定句,推测的可能性很大,译为“一定”;would常用于虚拟,不用于推测;need表示推测时,常用于否定句。由此可知选B。[来源:https://www.wendangku.net/doc/a311989832.html,]

3.【解析】选D。考查情态动词的用法。句意:我玩得再开心不过了——这是完美的一天。D 项表示不可能做过……,这里是用比较级的否定形式表示最高级的意思,故选D。A项表示本不该做却做了……;B项表示本不必做却做了……;C项将不会做……,用于与过去事实相反的虚拟语气。

4.【解析】选A。考查情态动词的用法。句意:——你的眼为什么那么红?昨晚你肯定没睡好。——是的,我熬夜写一篇报道了。A项can’t have don e表示对过去的否定推测;B项表示“禁止,不允许”,不能用于对过去的推测;C项needn’t have done表示过去不需要做某事(但却做了);D 项不能用于对过去的推测。

5.【解析】选D。考查情态动词。句意:——你这个周六要干什么?——我不太确定。我可能去滚石乐队的音乐会。由“我不太确定”可以判断应该选择可能性不是很大的情态动词might, 故选D;A项表示“必定,必然”;B项为“will”的过去式,往往表示意愿或请求;C项表示“应该”。

6.【解析】选D。考查情态动词的用法。句意:Harry感到不舒服。他一定是在昨晚的聚会上喝了太多的酒。根据句意是对发生在过去的情况的推测,用must have done。

7.【解析】选A。考查情态动词。句意:没有人能比他更慷慨大方,他拥有一颗金子般高尚的心灵。could可能;must必须,一定(表示非常肯定的猜测,不用于否定句);dare敢;need需要。根据句意选A。

8.【解析】选A。考查情态动词。句意:孩子们一定在森林里迷路了;否则他们会按照预定时间来到湖边营地的。根据后半句“would have been”可知是对过去事情的虚拟,must have done 表示对过去发生的事情的肯定推测,根据句意,应选A。

9.【解析】选A。考查情态动词。句意:——你不需要带伞,不会下雨。——哦,我不知道。也许会下雨。might表示不太确定。由I don’t know可知A项符合句意。B项表示“需要”;C项表示“意愿”;D项表示“应该”。

10.【解析】选C。考查情态动词。句意:当他正寻找一个主意的时候,尽管他试图入睡,但是他就是无法睡觉,直到把主意想出来。could表能力,意为“能够,可以”,couldn’t是其否定形式。11.【解析】选B。考查情态动词。句意:当我是一个孩子的时候,无论什么时候想看电视都可以。could在此表示“可以”。

12.【解析】选C。考查情态动词。句意:不管她怎么用力推,门总是打不开。shouldn’t不应该,couldn’t主观的不能,wouldn’t不肯,不可能,总是不;mightn’t可能不。

4.【解析】选C句意:这里现在很暖和,我们还没有必要打开供暖设备。c ouldn't “不能”;mustn't “禁止,不许”;needn't “不必”;wouldn't “不愿,不想”。

5.【解析】选D句意:这项新法律说,人们在喝酒之后禁止开车。故此处用mustn't表示“禁

止”。

12.【解析】选B might表示可能性。句意:我走近了,听见他们在说汉语。然后我就以在中国可能的打招呼方式说了声“你好”。must“必须,偏要”,can“能够,可能”,should“应该”,均不符合句意。

13.【解析】选C此处must表示“偏偏,非要”。句意:如果你非要吸烟,请到外面去。14.【解析】选D句意:——我真不喜欢詹姆斯,你为什么邀请他?——不要担心,他有可能不来,他说过他对他的计划不确定。might “可能”,可能性较小。由句意可知,选D项。15.【解析】选D句意:我不必担心我的周末,我总是在周末到来之前做好计划。can't“不能”;mustn't“禁止,不许”;daren't“不敢”;needn't “不必”。

16.【解析】选B根据语境可知,手提包失而复得。这里是猜测,但并不确定,意为“这个手提包可能会被偷”。might的可能性小。

17.【解析】选B will “愿意,要”,用来表示一个人的意愿;must “必须,一定”,用来表示必要性;may “可以”;can “能够,会”。由空前的I'm afraid可知,此处应侧重必要性。句意:——我现在通知他日程表的变动吗?——恐怕你必须通知他,以免他开会迟到。故选B 项。

18.【解析】选D句意:——你们的新保姆怎么样?——我们不可能再请到更好的了。我们的孩子非常喜欢她。“We couldn't ask for a better one.”中couldn't与better连用表示“不可能更好”。如I couldn't agree more.表示“我非常同意”。故选D项。
