A.shall B.should C.must D.will

【答案】D

【解析】

【详解】

考查情态动词辨析。句意:——妈妈,小雷又弄坏了他的玩具。——没事的,你看,意外总会发生。A. shall将要,会;B. should应当;C. must必须;D. will总是。Will可以表示习惯,意思为“惯于,总是”。故D选项正确。

【点睛】

will/would是情态动词,其表达的意思如下。

(1)表示意志或意愿:决心,愿意,……好吗?

We will do our best to save the child. 我们会尽力抢救这个孩子。

I told her to stop crying, but she just wouldn’t listen. 我叫她别哭,可她就是不愿听。

注:表示请求、建议或征求对方意见时,用Would you…? 比用Wi ll you…?更婉转。如:Will/Would you please keep the door open? 请让门开着好吗?

Will/Would you go with me? 你愿意和我一起去吗?

(2)表示真理或习惯:惯于,总是。如:

Oil will float on water. 油总是浮在水面上。

She will listen to music alone in her room for hours. 她独自在房间里听音乐,一听往往就是几小时。

He would get up early when he lived in the country. 他住在乡下时总是早起。

(3)表示要求:一定,必须。如:

(4)表示猜测:可能,大概。如:

This will be the house you’re looking for. 这大概就是你找的那所房子了。

(5)表示功能:能。如:

This auditorium will/would seat one thousand people. 这个礼堂能容纳一千人

分析句子可知,本句中的will表示习惯,意思为“惯于,总是”且符合语境。故D选项正确。

2.According to a newly released regulation on online video services, no one _____ generate, release or spread fake news or information by using such technologies.

A.can B.shall C.will D.may

【答案】B

【解析】

【详解】

考查情态动词。句意:根据最新发行的关于网络视频服务的规章,任何人都不可以使用此类技术生成、发行或者传播虚假消息。A. can 能够,有时会;B. shall 一三人称表示征求对方意见;二三人称陈述句,表示允诺、威胁、恐吓或法律条文的规定。C. will 意愿;D. may 也许,可能。根据前面的regulation(规定)可知,本题选shall更加合理。故选B。

3.Look! There are so many mistakes in your composition. You ________ have fixed full attention on it.

A.can B.should

C.need D.might

【答案】B

【解析】

【详解】

考查情态动词。句意:看!你的作文里有那么多的错误。你本应该把所有的注意力都集中在它上面的。表示“本应该做但实际上没有做”应该用should have done结构,can have done 表示可能;need表示需要;might have done表示可能做过某事;故选B。

4.—It’s already 11 o’clock , and he ______ have been here half an hour ago.

—Maybe he got caught in the rain.

A.must B.ought to

C.may D.can

【答案】B

【详解】

考查情态动词。句意:已经11点了,他半小时前就该到了。A. must have done必定做了…(表示对过去的推测);B. ought to have done 本应该做的;C. may have done可能已经做过某事;D. can have done本来可以做的(但没有做),根据题意,故选B。

5.What a pity! Considering his ability and experience, he ___________ it better.

A.need have done B.must have done

C.can have done D.might have done

【答案】D

【解析】

【详解】

考查虚拟语气中的情态动词。句意:真遗憾啊!考虑到他的能力和经验,他也许可以做得更好。can have done较少使用此结构,表示对过去行为的怀疑;用于疑问句时意为“难道

真的做了吗”,表示怀疑;need have done需要做某事,实际上却未做(表示虚拟语气);must have done一定做了某事(表示对过去发生的事情的肯定推测);might have done表示对发生过的事情的推测,意思是“可能已经”或“也许已经”,用于肯定句中。故D正确。【点睛】

本题是高考必考考点,一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事;shou ldn’t have done 本不应该做而实际做了。need have done本有必要做某事而没做;needn’t have done本没有必要做某事;注意没有mustn’t have done的形式。

6.Frankly speaking, I am not sure whether I ________ this in the old days with that kind of equipment, which looks quite odd and ridiculous.

A.should have done B.need have done C.would have done D.must have done 【答案】C

【解析】

【详解】

考查情态动词+have done。句意:坦率地说,我不确定在过去我是否会用这种设备做这件事,这看起来很奇怪和可笑。A. should have done表示本应该做某事,而实际上没有做某事;B. need have done表示本来需要做某事而没有做;C. would have done虚拟语气,表示对过去事情的假设,意思是“本来会做”;D. must have done表示对过去事情的肯定推测,译成“一定做过某事”。由“in the old days”可知,本句表示对过去事情的假设。故选C项。

7.I love the weekend, because I ________ get up early on Saturdays and Sundays. A.mustn’t B.needn’t

【答案】B

【解析】

【详解】

8.While it wasn’t the goal of the trip, I was rewarded with fresh insights, ones that ________ to me during the regular course of business.

A.might never happen B.could never have happened

C.should not happen D.needn’t have happened

【答案】B

【解析】

【详解】

考查虚拟语气。句意:虽然这并不是这次旅行的目的,但我得到了一些新的领悟,那些领悟在我的日常生活中是本不可能发生的。此处考查虚拟语气,“我得到新的领悟”发生在过去,故此处是与过去事实相反,应用could/might/would/need/should+have done,“本不可能发生”是could never have happened,故选B项。

【点睛】

本题考查“情态动词+have done”的虚拟语气,其常用表达有:

could have done本能做某事而未做couldn’t have done不可能做了某事

should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了

【解析】

【详解】

考查情态动词。句意:对我来说,很不正常,如此近的邻居居然不认识。A. could可能,能够;B. would将;C. should竟然;D. might可能,也许。should 作为情态动词,可以用来表示意外、惊喜或者在说话人看来是不可思议的,常常译为"竟会"、"居然",住的这么近的邻居居然不认识。表示意外,所以答案选C。

【点睛】

考点:考察情态动词

高中英语三大类题型超详细解题技巧

1 短文改错 增强语感,宏观把握 短文改错是一种综合技能,主要在于检测考生发现、判断、纠正文章中错误以及在语篇中综合运用英语知识准确性的能力。 短文改错与书面表达一样,最能反映一个人的语言功底。考生在该题上失分最厉害,因为此题而影响英语总成绩的占大多数。 一、短文改错的复习重点 1、考生必须熟悉设错方式:多词、少词、错词。 ⑴多词现象大多出现在冠词、介词、助动词、连词、语义重复及行文逻辑等方面。 ⑵少词现象主要出现在冠词、介词、副词、助动词、不定式符号to、连词等。 ⑶错词现象主要在冠词、介词、名词单复数、动词时态、非谓语动词、主谓一致、代词、连词、词形。 2、考生平时应加强基本功训练,用一个“错题集”把自己或同学在书面表达中出现的错误归纳一下,以便考前复习。 二、对全文的宏观把握

学生应把改错内容当作一篇小短文来理解,这样能对短文有个宏观把握,对上下文有全面的了解。 在理解篇章的基础上逐句审读,分析判断,上下兼顾,把明显的、拿的准的题先做完,这样可以缩小包围圈,也有助于对全文的进一步理解。 三、从语法角度审查 1、查看时态是否一致。 My favorite sport is football. I was a member of our football team. 全文都是用的一般现在时,此句中的was显然与上下文语境不符,应改为am。 2、查看主谓是否一致。 Anyone may borrow books, and it cost nothing to borrow them. cost应改为costs,因其主语是it(为形式主语),且上下文均为一般现在时。 3、查指代是否一致。 The Smiths did his best to make me feel at home.句中的主语the Smiths表的是Smith一家人,因此指示代词his应改为their。 4、查平行结构是否平行一致。 由and, or, but, either...or..., neither...nor..., not only...but also..., as well as等并列连词和词组连接的结构可称为平行结构。 It was very kind of them to meet me at the railway station and drove me to their home. 句中的drove显然与and前面的to meet不平行,应改为drive。

[高考必看]高考英语答题技巧解题方法集锦

高考英语答题技巧解题方法集锦 (仅供参考) 听力测试的主要形式有:对话理解,短文理解。对话理解是考查学生在一定语境或情景中所表现出的快速反应、推理判断能力;短文理解则是在此基础上考查学生对一个结构比较完整,意义相对连贯的语段的理解能力,是一种高层次、有难度的听力测试形式。 【高考英语听力考试的测试点】 1、理解对话的主旨大意 2、获取对话中具体信息 为了说明和解释主旨,对话或独白中需要一些具体信息,如时间、地点、人物、年代、价钱等,这些信息对理解对话,把握对话主旨是不可缺少的内容,且在试题中占相当大的比例。这类题要求学生在听清,听懂信息的同时,还要对所听到的信息做简单的处理。有的也需要考生进行简单的计算。 3、推断对话发生的背景、地点及对话者之间的关系。对对话背景、地点、 对话者之间关系的理解程度,体现了一个人对口语的理解能力。 4、理解领会对话的观点、态度及意图 这类考题要求考生不但能理解录音原文的主旨大意,而且还要通过文中的重要细节、具体事实,揣摩、推断说话者的意图、观点和态度等,这类题能测试出考生在听力方面的综合素质。 【培养良好的听力习惯,掌握正确的答题技巧】 多听是提高听力的前题,但如何去听,如何获得准确的信息,则就不是多听听能解决的问题了。多听是增强语感,提高听力之本,若再加上正确的听力方法,掌握必要的技巧及对策,则可获得事半功倍的效果。 1、利用听录音前的时间,迅速地捕捉每个小题题干选项所提供的信息,预

测短文或对话可能涉及到的内容,这样听录音材料时就有的放矢,有所侧重,提高答题的准确率。 2、克服犹豫不决的毛病,对自己有把握的试题应快速作答,对无把握的试 题也要在所听信息的基础上排除错误选项,进行优化处理。不会作答的,立即暂时搁置,准备听新的题目。 3、目前高考听力测试中短文理解大部分是记叙文或讲话稿,所以听录音时 重在听懂每句话的意思和内涵,注意捕捉文中所涉及的人物(who)、事件(what)、时间(when)、地点(where)、原因(why)、方式(how)、程度(how long,how soon,how much)、数字(how many/how much)、选择(which…)等,以便检查答案。 4、注意听短文的首句和首段,文章的开首和开首段,往往是对短文内容的 概括,如讲话目的、主要内容、作者、论点、故事发生的时间、地点及事由等。 5、不管听什么材料,注意力一定要集中在整体内容的理解上,千万不能只 停留在个别单词或单句上,听不清时马上放弃,不要强迫自己听清每一个词,要把重点放在听关键词即实词上,一边听一边把要点及回答问题的关键词记下来。 【单项填空答题技巧、解题方法】 单项填空主要考查三个方面:1、英语语法知识;2、对近义词或习惯用语的辨析;3、日常交际用语。这三个方面各有其内在规律,因此了解这些规律,掌握这些规律,就能逐渐形成答好单项填空题目的解题技巧。高考的学生要想快又准地做好单选题,必须具备下列技巧: 1、题眼法:"题眼"是指题干中的关键词或关键符号,它具有提示信息的作 用。一旦抓住了它,就能掌握选择的依据。 2、还原法:把倒装式、强调式或疑问式的题干变换为陈述句,再选就容易 多了 3、归类法:根据句意,把选项分组归类,缩小范围,提高做题的速度和准

高中英语情态动词讲解与练习(含答案)

高中英语语法之情态动词 (一)情态动词的定义:情态动词表示说话人对某一动作或状态的态度。 (二)情态动词的特点:1)有一定词义;2)不受主语人称和数的变化影响;3)与主要动词 的原形(或称不带to的不定式)一起构成谓语(除ought to作固定词组看待)。 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. (三)情态动词有四类:①只做情态动词:must,can(could),may(might),ought to 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) ④具有情态动词特征:have(had,has) to,used to ⑤情态动词表猜测 (四)情态动词的基本用法 1. can (could) 1)表示能力,could主要指过去时间。 Two eyes can see more than one. 两只眼比一只眼看得清。 Could the girl read before she went to school? 这女孩上学前能识字吗? 2)表示可能(理论上或是逻辑判断上)。 The temperature can fall to –60℃, that is 60℃ below freezing. 气温可降至—60℃,也就是零下60℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′

A. will B. would C. should D. must ②There _________ be any difficulty about passing the road test since you have practiced a lot in the driving school. A. mustn’t B. shan’t C. shouldn’t D. needn’t (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! A. wouldn’t B. can’t C. mustn’t D. needn’t ②She ______ have left school, for her bike is still here. A. can’t B. wouldn’t C. shouldn’t D. needn’t ③It is usually warm in my hometown in March, but it _____ be rather cold sometime.
