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】should的用法1、should 作为情态动词,通常用来表示现在或将来的责任或义务,译作“应该”、“应当”,这时它可以和 ought to, be supposed to 互换使用.例如:You should (= ought to ) tell your mother about it at once.2、should 作为情态动词,可以用在条件状语从句中,表示语气较强的假设,译作“万一”、“竟然”,这时也可将 should 置于从句之首,即将 should 放在主语前面,而省略从属连词 if。
例如:If you should fail to come, ask Mrs Chen to work in your place. (= Should you fail to come, ask Mrs Chen to work in your place. )3、should 作为情态动词,可以表示谦逊、客气、委婉之意,译为“可……”、“倒……”。
例如:I should say that it would be better to try it again.4、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.尤其在以 why, who, how 等开头的修辞疑问句或某些感叹句中常常译为“竟会”、“居然”。

【英语】高一英语情态动词专题训练答案一、单项选择情态动词1.would可以表达过去常常做的事,过去习惯发生的动作:Pirates would bury gold in a cave. 海盗们常常把黄金藏在山洞中。
We would take a walk along the river. 我们过去常常沿河散步。
3. would后接like、love、mind等动词,表示要求、邀请、希望或询问,此时不是说过去,而是对现在的询问:Would you like to come to my party? 你愿意来我的派对吗?Would you mind coming with us? 你介意和我们一起吗?比如本题,would 表示婉转的请求,征求对方的意见,故选A。
2.We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible.A.Should B.Were C.Would D.Had【答案】A【解析】【分析】【详解】考查虚拟语气。
句意:我们将对我们的计划做最后决定。
如果你改变主意,请尽快通知我们。

2)If I were you, I would do it at once.→Were I you, I would do it at once.假若我是你,我就会马上做。

高一英语情态动词专题训练概说助动词(auxiliary)主要有两类:基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。
基本助动词有三个:do, have和be;情态助动词有十三个:may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是,在协助主动词构成限定动词词组时,具有作用词的功能:1)构成否定式:He didn’t go and neither did she.The meeting might not start until 5 o’clock.2)构成疑问式或附加疑问式:Must you leave right now?You have been learning French for 5 years, haven’t you?3)构成修辞倒装:Nowhere can he obtain any information about his sister.Hardly had he arrived when she started complaining.4)代替限定动词词组:A: Who can solve this crossword puzzle?B: Tom can.A: Shall I write to him?B: Yes, do.情态助动词的特征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、-ing分词和-ed分词形式: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.情态助动词的意义和用法情态助动词从最普通的意义上来说,是修饰分句意义的一种方式,它可以反映说话者对其表述是否真实和可能的程度作出判断。
但不同的情态助动词本身所包含的意义和用法又不同,下面逐个分析。
1)can和could的用法1.表示能力或客观可能性,还可以表示请求和允许。
如:Can you finish this work tonight?Man cannot live without air.—Can I go now? —Yes, you can.注意:①could也可表示请求,预期委婉,主要用于疑问句,不可用于肯定句,答语应用can(即could不能用于现在时态的简略答语中)。
如:Could I come to see you tomorrow?Yes, you can. (否定答语可用No, I’m afraid not.)②can表示能力时,还可用be able to代替。
如:I’ll not be able to come this afternoon.2.表示惊异、怀疑、不相信的态度。
(主要用在否定句、疑问句或惊叹句中)Can this be true?How can you be so careless!This cannot be done by him.3.“can(could) + have + 过去分词”的疑问或否定形式表示对过去发生的行为怀疑或不肯定。
如:He cannot have been to that town.Can he have got the book?2)may和might的用法1.表示许可。
表示请求、允许时,might比many的语气更委婉一些,否定回答时要用mustn’t表示“不可以”、“禁止”、“阻止”之意。
如:You may drive the car.—Might I use your pen? —No, you mustn’t.用May I ... 征询对方许可在文体上比较正式,在口气上比较客气。
在日常口语中,用Can I ... 征询对方意见在现代口语中更为常见。
2.用于祈使句中表示祝愿。
如:May you succeed!3.表示推测、可能(疑问句不能用于此意)。
He may be very busy now.4.“may(might) + have + 过去分词”表示对过去发生的行为的推测。
如:He may not have finished the work.3)must和have to的用法1.表示必须、必要。
如:You must come in time.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。
—Must we hand in our exercise books today?—Yes, you must. (No, you don’t have to.)2.“must be + 表语”的结构表示推测,它的否定或疑问式用can代替must。
This must be your pen.3.“must + have + 过去分词”的结构常用在肯定句中,表示对过去发生的行为的推测。
它的否定或疑问式用can代替must。
He must have been to Shanghai.4.have to的含义与must相似,两者往往可以互换使用,但have to有各种形式,随have 的变化而定。
must与have to有下列几点不同:①must表示的是说话人的主观看法,而have to则往往强调客观需要。
如:The play is not interesting. I really must go now.I had to work when I was your age.②must一般只表现在,have则有更多的时态形式。
③二者的否定意义不大相同。
如:You mustn’t go. 你可不要去。
You don’t have to go. 你不必去。
④询问对方的意愿时应用must。
如:Must I clean all the room?4)dare和need的用法1.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。
如:You needn’t come so early.—Need I finish the work today?—Yes, you must.注意:needn’t + 不定式的完成式“表示本来不必做某事而实际上做了某事”。
如:You needn’t have waited for me.2.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。
如:How dare you say I’m unfair.He daren’t speak English before such a crowd, dare he?3.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 river.He does not dare (to) answer.Don’t you dare (to) touch it!I wondered he dare (to) say that.He needs to finish it this evening.5)shall和should的用法1.Shall用于第一人称,表示征求对方的意愿。
如:What shall we do this evening?2.Shall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?3.Shall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)4.Should表示劝告、建议、命令,其同义词是ought to;在疑问句中,通常用should 代替ought to。
如:You should go to class right away.Should I open the window?Should的含义较多,用法较活,现介绍三种其特殊用法。
请看下面的句子:①I should think it would be better to try it again. 我倒是认为最好再试一试。
