答案

[一模题组]

1.选C考查虚拟语气。句意:“要不是你及时警告,我们也许已经陷入很大的麻烦中了。”“好了,你知道我们是朋友啊。”but for意为“要不是,如果没有”,后接名词,相当于一个if条件句,根据句意可知,本题中if条件句与过去事实相反,即if you hadn't warned us,此时主句谓语动词应用would have done表示。故C项正确。

2.选D考查情态动词。句意:“我可以用支票支付吗?”“对不起,先生。我们旅馆的管理规定是必须用现金支付。”情态动词shall在陈述句中用于第一、三人称可表示命令、规定等。故选D项。

3.选D考查情态动词。句意:“会是谁没锁门呢?”“可能是迈克,因为他总是忘事。”would“将”;should“应该”;must“一定”;could“可能”。

4.选B考查虚拟语气。句意:我愿意毕业后参加工作,但我父亲却愿意我出国进修。“would rather+动词原形”表示:愿意现在或将来做某事,故第一空用动词原形;在“would rather+that从句”句型中,that从句的谓语动词需用“一般过去时或过去完成时”,用一般过去时表示现在或将来,用过去完成时表示过去。综上所述答案为B项。

5.选C考查情态动词。句意:“截止日期就要临近了,但我挑战那项任务又失败了。”“让我的弟弟试试好吗?”shall与第三人称连用,用于一般疑问句表示请求对方的许可。will用于一般疑问句表示请求对方允许时,需与第二人称连用,故排除A项。may 用于一般疑问句表示请求对方允许时,需与第一人称连用,故排除B项;must意为“必须,偏偏”,不符合句意,故被排除。

6.选D考查情态动词。句意:“是谁又那么做了?”“你还有必要问吗?当然是小汤姆了!”Need you ask?意为“还有必要问吗?”故答案为D项。B、C两项意为“你可以问一问吗?”是向对方(you)提出建议,不符合句意,故被排除。征求对方允许或提出建议时,没有“Might you ...?”句型。

7.选D考查情态动词。句意:莉莎很可能不想去旅游,因为她讨厌旅游。may well do sth.(=be very likely to do sth.)意为“很可能做某事”。

8.选A考查情态动词。句意:如果你非要接听电话,你最好靠路边停车。must“偏要,非要”;will“将,愿意”;can“能,可能”;may“可能,可以”。

9.选C考查情态动词。句意:这只大熊猫看起来很温顺。但如果你把它惹恼了,它有可能非常凶猛。情态动词can在此意为“有时可能会”,表示偶尔的可能性。

10.选D考查情态动词。句意:“Mike英语考试又没有及格。”“你还能指望什么?难道你不认为他应该花更多的时间学习英语吗?”should have done表示“本来应该做某事,但实际上并未做”,符合题意。

11.选D考查情态动词。句意:广州恒大足球俱乐部运动员最近表现一直很好,所以按道理说他们应该能赢得决赛。根据句意可知,此处用情态动词should表示很大的可能性,常译为“按道理说应该”。

12.选C考查虚拟语气。句意:“为什么我们要这么早起床?”“如果我们错过航班,我们将不得不在这里再待一天。”此处为if引导的虚拟条件句,因表示与将来的事实相反的假设,从句谓语动词可以用should do/did/were to do,所以选择C。

13.选C考查虚拟语气。句意:“我要到旧金山去几天。”“我真羡慕你。我多希望我能出去休一段时间的假啊。”在wish后的宾语从句中,通常用虚拟语气,此处表示对将来的虚拟,故用情态动词could。

14.选A考查虚拟语气。句意:“你去听那个客座教授的讲座了吗?”“没有。我本来要去听的,但这几天我一直忙着在医院照看我奶奶。”这里叙述的是与过去事实相反的假设,表示“本来要做某事却没做”,应用would have done。故选A。

15.选D考查虚拟语气。根据前半句中的“was delayed”“yesterday”可知,此处是对过去发生的事情的虚拟,所以用would have done。

[二模题组]

1.选A考查情态动词。句意:“把你的秘密告诉我吧。”“我不会告诉你的。如果告诉你了,这就不是秘密了。”这里表示说话人的意志或决心,故用won't。

2.选B考查情态动词。句意:汉语词语“土豪”竟然变得如此流行,以至于被广泛应用,这超出了我的想象。should在此处意为“竟然”,表示惊讶、惊奇。故选B。

3.选B考查情态动词。句意:“Peter已经出发了吗?他说他会与我们一起去远足。”“他肯定已经出发了。他是一个信守诺言的人。”根据“He is a man of his word.”可知,

答话人猜测Peter肯定已经动身了。must have done表示对过去情况的肯定猜测,符合语境。

4.选C考查情态动词。句意:“今天早上上班你为什么迟到啊?”“我正准备动身,可我的孩子偏偏醒了。”can可以表能力或表推测。may表示“可以”,表示可能性时语气较弱。will表客观将来或意志决心。must在此处意为“非得,偏偏”。

5.选A考查情态动词。句意:“出租车司机应为这起严重的事故负责。”“我非常赞同。他本不应该喝酒的。”should not have done sth.意为“本不应该做某事,但实际上却做了”。

6.选C考查情态动词。根据“Wonderful”可知,此处意为“我不可能过得比那更愉快了”,暗指当时过得最愉快。“can't/couldn't ...+比较级”可表达最高级含义,故选C项。

7.选D考查虚拟语气。句意:要不是观众们鼓励性的欢呼,我们队不可能赢得这么重要的比赛。根据该句中的“But for”可知,此处应用虚拟语气,表示与过去事实相反,再结合句意可知,应用couldn't have won。

8.选D考查情态动词。句意:你本没必要带这么多现金的,你知道那家店接受支票。needn't have done表示“本没必要做某事”,符合句意。故答案为D项。

9.选C考查情态动词。句意:杰克是个外向的孩子,平时很善良且乐于助人,但有时他也可能会发脾气。情态动词can可以表示理论上的可能性,意为“有时候会”。

10.选C考查情态动词。句意:“Mary不介意把她的电子词典借给你。”“她不必借给我了。我已经向Jane借了。”根据句意可知,应选needn't“不必”。

11.选D考查情态动词。句意:如果你不照我说的做,你就得不到晋升的机会,因为竞争太激烈了。shall用于第二、三人称可表示说话人给对方的警告,符合句意。

12.选C考查虚拟语气。if only表示“要是……就好了”,谓语动词应使用虚拟语气。根据“right now”可知,此处表示对现在的虚拟,因此谓语动词用过去式。

13.选C考查虚拟语气。句意:要是当初你听我的,那么我们现在就在聚会现场了。你挪过去,我来开车。if从句表示与过去事实相反的假设,而本空表示与现在的实际情况相反的假设,说话人此时还在路上,因此选C项。

14.选D考查虚拟语气与倒装。依据题干中的“you would become pretty rich and popular”可知,该句是对将来情况进行的假设,因此这里是if虚拟条件句的省略。if虚拟条件句中有should, had或were时if可省略,从句中should, were或had放到主语前,构成倒装。因此选D项。

15.选A考查虚拟语气与倒装。句意:“Helen, 后天你会去机场送Jack吗?”“如果他明天走的话,我就去送。”答语是对将来进行虚拟,所以if从句中谓语应该用一般过去式、were to+动词原形或should+动词原形。含有虚拟语气的条件状语从句中,如有had, should,were或could,可将if省略,把were, should, had或could置于句首。因此选A项。

[押题题组]

1.选D考查情态动词。句意:根据工厂的安全条例,所有的事故都必须上报给安全员。shall用于第三人称,在条约、规定、法令等文件中表示义务或规定,意为“应,必须”。故选D项。

2.选C考查情态动词。句意:眼科专家们已经意识到,眼睛大非但不是一个人的优势,事实上有可能是一个人的劣势。这里用can表示理论上的可能性,常译为“有可能”。

3.选C考查情态动词。句意:“放学了,我们怎么联系罗伯特?”“试试给他打电话。他住的离学校很近,按道理说这会儿他应该到家了。”语境说他住的离学校很近,因此这里用should表示很大的可能性,常译为“按道理说应该”。

4.选A考查情态动词。根据“You talk so much about London.”可知,空处应表示对过去事实的肯定推测,因此用must have done。can表示推测时常用于否定句或疑问句。

5.选A考查虚拟语气。句意:要不是李明在去年的入学考试中犯了那些错误,他原本可以通过考试的。由“But for”和“made”可知,这里表示与过去事实相反的假设,主句应用would have done,因此选A项。

6.选C考查情态动词。句意:中国不应该关注短期发展而是必须把精力集中在国家的长期发展上。should作为情态动词,意为“不应该”,符合句意。

7.选C考查情态动词。shall用于第三人称时,在条约、规定、法令等文件中表示义务或规定,意为“应,必须”。

8.选B考查情态动词。句意:昨天是个好天,我本不该带雨衣。needn't have done sth.“本不该做某事”,符合句意。

9.选A考查情态动词。句意:“你能开车送我去火车站吗?我要晚了。”“我会走最近的路线。你一定能及时赶上火车。”shall可以用于第二、三人称,表示允诺、命令、警告、威胁等语气。

10.选A考查情态动词。句意:“凯特,吉姆这些天在哪儿呢?”“他前几天请病假了。他有可能住院了。”此处的might表示可能性,符合语境。

11.选A考查情态动词。句意:如果你知道急救方法,便能够在紧急状况下更加冷静,更有帮助。can表示理论上的可能性,符合题意。

12.选C考查虚拟语气。句意:“很遗憾!上周的音乐会上没有看到你。”“但愿我抽得出时间。”从第一句话看出答话者没有去听音乐会,根据答语可知,此处是对过去情况的虚拟,因此选C。

13.选A考查虚拟语气。句意:如果不是邮政罢工,我寄出的那封家书也不会被耽搁。由“had it not been for ...”可看出,邮政罢工发生在过去,因此,家书寄出后被耽搁也发生在过去。might not have done表示对过去事情的虚拟假设,意为“原本不可能做某事”。

14.选B考查虚拟语气。由时间状语“this Saturday evening”可知,此处是对将来的虚拟,因此if从句要用“should/were to+动词原形/did(be动词用were)”,故选B。

15.选A考查固定短语和虚拟语气。句意:他们主张我们反对的那个提议应该在下次会议上重新讨论。be opposed to sth.为固定短语,由此可知此处首先需要补充完整,故排除B、D两项;再分析句子成分可知,advocate后的从句为宾语从句,需要用虚拟语气,即“(should +)动词原形”,故A项正确。

虚拟语气用法总结及详细解析

虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告,建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实,或难以实现的情况,甚至表达彻底相反的概念。此外,如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird,I would be able to fly in the air. 如果我是一只小鸟,我就能在空中飞行。 I wish I could pass the examination. 我希望我能通过考试。

If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪,我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话,我就会告诉她这件事的始末。 4、有时,虚拟条件句中,结果主句和条件从句的谓语动作若不是同时发生时,虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 ①从句的动作与过去事实相反,而主句的动作与现在或现在正在发生的事实不符。 If I had worked hard at school, I would be an engineer, too.如果我在学校学习刻苦的话,我现在也会成为一个工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话,我们现在就不会来这里了。 ②从句的动作与现在事实相反,而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话,我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话,他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时,if可以省略,这时条件从句要用倒装语序,即把were, should, had等词置于句首,这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话,我们就派他去。 Were she here, she would agree with us.如果她在这儿的话,她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话,我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句,否定词not应置于主语之后,而不能与were,should,had 等缩略成Weren't,Shouldn't,Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏,我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time,I would come. 假若我有时间,我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来,暗含在副词、介词短语、上下文或其他方式表示出来,这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中,如without…, but for…,otherwise(要不是因为)等 But for his help, we would be working now. (要不是他的帮助,我们还会在工作呢。

语 法 讲 解 ——虚拟语气

语法讲解 ——虚拟语气 英语中有三种不同的语气:陈述语气,祈使语气和虚拟语气。虚拟语气表示动作或状态与事实相反,或不可能发生的情况。 1. 表示与现在事实相反或不可能发生:条件状语从句:一般过去时(虚拟语气中be→were)主句用:would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生:条件状语从句:had+过去分词;主句:would(should, could, might)+have+过去分词。If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生:条件状语从句: ①一般过去时②should +动词原形③were to+动词原形;主句:would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况

(1). 混合/错综型虚拟语气 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,称为‘错综条件句’,动词的形式要根据它所表示的时间作出相应的调整。 If you had followed my advice, you would be better now.(从句说的是过去,主句是现在) If I were you, I would have taken his advice.(从句是现在,主句是过去) (2)省略if的虚拟语气 如果从句中含有were/ should/ had时,则可以把这三个词置于句首,省略if.采用倒装语序。 If it should happen, what would you do? →Should it happen, what would you do? If he had recognized me, he would have come over. →Had he recognized me, he would have come over. (3) 含蓄虚拟条件句 有时候假设的情况不以if引导的条件从句形式表现出来,而是通过一个介词短语,连词或其他形式表示。常用的词或短语有:without, with, but for(要是没有), otherwise, or, but等。Without your help(=If we had not had your help), we could not have succeeded.
