虚拟语气

进门测试

1．（23-24高三下·广东中山·阶段练习）If he ______ hard at high school, he ______ a college student now.

A．studied; is          B．had studied; is         C．studied; would be    D．had studied; would be

【答案】D

【详解】考查虚拟语气。句意：如果他在高中时努力学习的话，他现在就是一名大学生了。study“学习”，be“是”。结合句意可知，If引导的条件状语从句，是对过去的假设，从句时态用过去完成时，用had studied；而主句是对现在的假设，时态用过去将来时，用would be。故选D。

2．（23-24高三上·陕西西安·期末）It is strongly recommended that the machine ______ maintained every year for safety reasons.

A．be                     B．will be                   C．is                           D．has been

【答案】A

【详解】考查谓语动词。句意：出于安全考虑，强烈建议每年对机器进行维护。分析句子结构和意思可知，这里考查that引导的主语从句的谓语动词，前面有recommend，从句谓语动词用虚拟语气should+动词原形，should可以省略，be是动词原形。故选A。

3．（23-24高三下·广东东莞·开学考试）He might have already recovered from his illness ________ the fact that he didn’t follow the doctor’s advice.

A．if it was not for  B．were it not for        C．if it should not be for       D．had it not been for

【答案】D

【详解】考查虚拟语气。句意：如果不是因为他没有听从医生的建议，他可能已经康复了。由主句中的might have recovered可知，这是对过去发生的事情的虚拟，所以if条件句中应该用过去完成时态，即if it had not been for...，在if引导的条件句中，如果if被省略，则把had提前，变为had it not been for...，故选D。

一、知识脉络

二、知识精讲

虚拟语气用来表示说话人的主观愿望或假想，所说的或者不是事实，或者与事实相反。

一、虚拟语气在非真实条件句中的应用

1.虚拟条件不同时，非真实条件句的形式

We would go with you if we had time.(与现在事实相反)如果我们有时间的话，就和你一起去。

In the past,if I'd wanted to see them,I would hare visited them in person.(与过去事实相反)

过去，如果我想见他们，我就亲自去拜访他们了。

4．（23-24高三上·福建·开学考试）We wouldn’t have called a taxi yesterday if Harold  (offer) us a ride home. (所给词的适当形式填空)

【答案】had offered

【详解】考查虚拟语气。句意：如果哈罗德让我们搭车回家，我们昨天就不会叫出租车了。offer“提供，表示愿意”。由前文wouldn’t have called可知，此处是对过去的虚拟，时态应用过去完成时。故填had offered。

5．（2024高三下·全国·专题练习）I am sorry I am very busy now. If I  (have)time，I would certainly go to the movies with you. (所给词的适当形式填空)

【答案】had

【详解】考查虚拟语气。句意：对不起，我现在太忙了。如果我有时间，我一定会和你一起去看电影。根据语境和句子结构分析，此句为虚拟语气句子，根据I am too busy now，可知此句是对现在的虚拟，句子从句用一般过去时，主句用would/could/should/might+do。故填had。

 

2.虚拟语气在省略if的条件句中的用法

当虚拟条件从句中含有were,had或should时，可以省略if,并把这些词提至句首。

Were I to meet him tomorrow,I should ask him about it.如果明天见到他，我会问他这件事的。

Had I had the money last year,I would have bought the house.如果我去年有这笔钱，我就会买了那座房子。

Should I have time,I would go and watch the football game.要是我有时间，我会去看那场足球赛的。

6．（23-24高三上·黑龙江哈尔滨·期中） it snow tomorrow, I would take the subway to work. (用适当的词填空)

【答案】Should

【详解】考查虚拟语气。句意：如果明天下雨，我会乘坐地铁去工作。分析句子结构，该句子使用了虚拟语气。从句是省略了连词if进行倒装，补充完整为“If it ________ snow tomorrow”。由时间词“tomorrow”可知与将来事实相反，从句要用should+动词原形的结构，所以空处填should，空格置于句首，首字母要大写，即Should。故填Should。

7．（21-22高一下·全国·课前预习）(be) I a bird, I would fly to see you at once. (所给词的适当形式填空)

【答案】Were

【详解】考查虚拟语气中的省略。句意：如果我是一只鸟，我马上就会飞过去看你。在虚拟语气中表示对现在情况的虚拟，be动词用were。此处为虚拟条件句应该为:：If I were a bird。此处省略了if的倒装句式，首字母大写。故填Were。

 

3.虚拟语气在错综时间条件句中的用法

有些条件句的主句谓语和从句谓语表示的动作发生的时间并不一致，这类句子称为错综时间条件句，这时主、从句谓语动词的形式应由各自的时间来确定。

If I were you,I would hare taken his advice.(从句是对现在情况的假设，主句是对过去情况的假设)

如果我是你，我就采纳他的建议了。

If he had followed the doctor's advice,he would recover now.

(从句是对过去情况的假设，主句是对现在情况的假设)如果他听从了医生的建议，现在他的病就好了。

8．（22-23高三上·河南南阳·阶段练习）Had you listened to the doctor, you (be) all right now. （所给词的适当形式填空）

【答案】would be

【详解】考查虚拟语气。句意：如果你听了医生的话，你现在就好了。根据句意和句子结构，此题考查省略if的错综时间条件句。从句部分为过去事实相反的假设，省略if后，助动词had置于句首，根据主句的时间状语now，主句部分应与现在事实相反，故设空处应填would+动词原形。故填would be。

9．（2022高三上·全国·专题练习）If he had spent more time practising speaking English before, he (be) able to speak it much better now. （所给词的适当形式填空）

【答案】would be

【详解】考查虚拟语气。句意：如果他以前花更多的时间练习说英语，他现在就能说得更好了。本句是虚拟语气含蓄条件句，now说明主句与现在事实相反，应用would do。故答案是would be。

 

二、虚拟语气在名词性从句中的应用

1.虚拟语气在宾语从句中的用法

(1)用于表示建议、命令、要求等动词后的宾语从句中。

10．（23-24高三下·全国·课后作业）The expert requests teenagers  (focus) on what they are doing and be responsible for their behaviour. (所给词的适当形式填空)

【答案】to focus/focus

【详解】考查动词不定式和虚拟语气用法。句意：专家要求青少年专注于他们正在做的事情，并对自己的行为负责。分析句子可知，此处为动词短语request sb to do sth“要求某人做某事”，所以此处为动词不定式作宾语补足语；此处也可为虚拟语气用法，request后接宾语从句（此处省略了引导词that）要用虚拟语气，从句谓语动词用(should) do，should可以省略。故填to focus/ focus。

11．（23-24高三上·陕西渭南·阶段练习）He insisted that we (change) our schedule, though no one really agreed with him. (所给词的适当形式填空)

【答案】change/should change

【详解】考查虚拟语气。句意：他坚持要我们改变日程安排，尽管没有人真正同意他的意见。insist表示坚持要求，所接的宾语从句一般用虚拟语气，其虚拟语气的结构为：(should) +原形动词，should可省略。故填change/should change。

 

 

(2)虚拟语气在wish后的宾语从句中的用法。

wish表示“但愿，要是……就好了”,后接宾语从句时，表示不能实现的愿望，从句应用虚拟语气。

 

12．（2023高三·全国·专题练习）I wish I(take) your advice last time, and then I wouldn't have been blamed by others. (所给词的适当形式填空)

【答案】had taken

【详解】考查虚拟语气。句意：我希望我上次接受你的建议，这样我就不会被别人责备了。虚拟语气通常用于wish后的宾语从句中，表示与事实相反或不大可能实现的愿望。通常有三种形式：①表示与现在事实相反的愿望，用过去时：②表示与过去事实相反的愿望，用过去完成时：③表示与将来事实相反的愿望，用could / would+ / might+动词原形。根据“last time”可知，此处表示与过去事实相反，从句用过去完成时。故填had taken。

13．（2022高三上·全国·专题练习）—Where are the children? The dinner’s going to be completely ruined.

—I wish they (not be) always late. （所给词的适当形式填空）

【答案】wouldn’t be

【详解】考查虚拟语气。句意：——孩子们在哪儿？这顿饭快要给搅黄了。——我多么希望他们别老是迟到。wish后的宾语从句应用虚拟语气，结合语境从句与将来事实相反，故应用would do且表示的是“不要老是迟到”。故答案是wouldn’t be。

 

(3)虚拟语气在would rather+that从句中的用法

从句谓语动词的形式如下：

对现在或将来的虚拟：过去式(be动词用were)

对过去的虚拟：had+过去分词

I'd rather you paid the money yourself.(对现在情况的假设)我宁愿你自己付钱。

I'd rather she hadn't come yesterday.(对过去情况的假设)我宁愿她昨天没来。

 

2.虚拟语气在主语从句中的用法

14．（2024高三下·全国·专题练习）It is essential that these application forms  (send) back as early as possible. (所给词的适当形式填空)

【答案】(should) be sent

【详解】考查虚拟语气与被动语态。句意：这些申请表必须尽早寄回。It is essential that...“……是至关重要的”，that从句中要用虚拟语气，谓语用should+动词原形，should可省略，从句中动词send与主语these application forms为动宾关系，故应用被动语态should be sent，should可省略。故填(should) be sent。

15．（23-24高一上·全国·课后作业）It’s our desire that you(provide) some money to fund our program, as well as offer us some practical suggestions. (用所给词的适当形式填空)

【答案】should provide/provide

【详解】考查虚拟语气。句意：我们希望你们提供一些资金来资助我们的项目，并给我们一些实际的建议。it是形式主语，that引导主语从句，desire后面的从句用虚拟语气should+动词原形，should可以省略，故填should provide或provide。

16．（23-24高三上·河北石家庄·开学考试）Obviously, it is high time that we (take) effective measures to tackle the problem. (所给词的适当形式填空)

【答案】took/should take

【详解】考查虚拟语气。句意：显然，现在是我们采取有效措施解决这个问题的时候了。it is high time that意为“到了……的时候了”，为固定句式，从句谓语应用did/were或should do。故填took/should take。

 

3.虚拟语气在表语从句/同位语从句中的用法

在表示主张、要求、建议、命令的名词(如suggestion,proposal,advice,demand,order,requirement等)构成的表语从句和同位语从句中，谓语动词常用“(should+)动词原形”的形式。

My suggestion is that we(should)walk home instead of takinga taxi.我的建议是我们走着回家，而不是坐出租车。

Doctors give us a piece of advice that we(should)pay moreattention to our health.医生们建议我们更加关注自己的健康。

 

三、虚拟语气在一些其他句式中的应用

17．（2024高三下·全国·专题练习）The Antarctica is so mysteriously described by some people. If only I  (be) there before! (所给词的适当形式填空)

【答案】had been

【详解】考查虚拟语气。句意：有些人对南极洲的描述如此神秘。要是我以前去过那里就好了！If only引导的条件状语从句，对过去事情的虚拟，故谓语用过去完成时。故填had been。

 

三、解题方法

1.时间暗示法

在解答虚拟语气试题时，要注意找出句子中动作发生的时间，这是解答此类试题的关键。

例：(天津市静海一中高三月考)Had I knownabout this computer program,a huge amount of time and

energy_________(save).

A.would have save

B.would save

C.would have been saved

D.would be saved

解析句意：如果我了解这种电脑程序的话，就节约了大量的时间和精力了。分析句子结构并结合句意可知，此处是省略了if的虚拟条件句，表示与过去事实相反的假设，所以主句谓语动词应用“would/could/should/might have+过去分词”的形式；主语a huge amount of time and energy和动词save之间是被动关系，所以应用被动语态。结合选项可知，选C。

2.语气暗示法

正确判断题干中所暗含的语气，是虚拟语气还是陈述语气，也是正确解答此类试题的关键。

例：(江西省南昌市八一中学高三期中)Theteacher insisted that every minute _________(make)full use of todo the work well.

解析 句意：老师坚持要求要充分利用每一分钟把工作做好。根据句意可知，此处insisted作“坚持要求”讲，其后跟从句时应用虚拟语气，即从句谓语动词应用“(should+)动词原形”的形式；every minute与make full use of之间是被动关系，所以应用被动语态。答案时(should)be made

3.重要词汇、句型提示法

在虚拟语气试题中，有些单词、句型是解题的关键，如order,advise,wish等，考生应牢固掌握此类单词和句型的特殊用法。

例：(河北省石家庄一中高三二模)The doctorrecommended that you _________(not)swim after eating a largemeal.

解析句意：医生建议吃得太多后不要去游泳。表示“命令、建议、请求、要求”的动词后跟宾语从句时，从句应用虚拟语气，即从句的谓语动词应用“(should+)动词原形”的形式。答案shouldn't

 

 

真题回顾

一、单项选择

1．（23-24高三下·广东东莞·开学考试）The surgeon recommended the patient ________ in no time.

A．to be operated    B．operate on              C．should operate         D．be operated on

【答案】D

【详解】考查虚拟语气。句意：外科医生建议病人马上动手术。英语中表示请求、要求、命令或建议等意义的动词所接的宾语从句一般用虚拟语气，其虚拟语气的结构为：(should) +原形动词，should可省略；分析句子可知，“the patient ________ in no time”是动词recommended(建议)后宾语从句，应使用虚拟语气；从句中谓语operate on(给……动手术)与主语patient(病人)之间是被动关系，用虚拟语气和被动语态形式should be operated on，should可省略。故选D项。

2．（23-24高三上·黑龙江大庆·期末）He suggested that the problems ______ paid special attention to.

A．referred to being                                   B．referring to being    C．referred to be    D．referring to be

【答案】C

【详解】考查非谓语动词和虚拟语气。句意：他建议应该要对涉及到的问题给予重视。分析句子成分可知，suggested后为that引导的宾语从句，从句应用虚拟语气(should) do，又因宾语从句的主语为the problems，所以谓语动词应为(should) be paid；refer to“涉及，提到”与the problems是被动关系，应为过去分词形式作后置定语修饰前面的名词the problems。故选C。

3．（23-24高三上·陕西西安·阶段练习）I would rather Tom ______ to see me in the office instead of at home tomorrow.

A．would come       B．had come               C．came                      D．is coming

【答案】C

【详解】考查虚拟语气。句意：我宁愿汤姆明天来办公室找我，而不是在家里。would rather后的宾语从句使用虚拟语气，根据后文tomorrow可知表示与将来事实相反用一般过去时，应用came。故选C。

4．（19-20高三上·天津北辰·期中）Richard is so tired after work that he feels ________ he could sleep for 24 hours.

A．as if                  B．even though            C．in case                    D．now that

【答案】A

【详解】考查连词词义辨析。句意：Richard下班后太累了，他觉得自己好像能睡24小时。A. as if好像，似乎；B. even though尽管，即使；C. in case万一，假使；D. now that既然。根据空前的Richard is so tired after work that he feels和空后的从句he could sleep for 24 hours可知，表示与将来事实相反的情况，因此空处可用表示虚拟语气的连词as if。故选A项。

5．（22-23高三上·天津武清·期中）It’s a pity that such a talent as Jerry ______ leave his favourite work in that company.

A．need                 B．could                     C．should                    D．may

【答案】C

【详解】考查虚拟语气。句意：像杰瑞这样的人才竟然离开了他最喜欢的工作，真是太遗憾了。“It is a pity+that从句”意为“竟然；居然”时，表示出乎意料的事情，that后的从句要用虚拟语气，即从句谓语用“should+动词原形”。故选C。

 

二、语法填空

6．（2024高三下·全国·专题练习）My suggestion is that more people from all walks of life  (encourage) to finance the project with their deeper love for these children. (所给词的适当形式填空)

【答案】should be encouraged/be encouraged

【详解】考查谓语动词。句意：我的建议是，应该鼓励更多来自各行各业的人怀着对这些孩子更深的爱来资助这个项目。分析句子结构可知，此处应为表语从句的谓语，suggestion意为“建议”，其后的表语从句的谓语动词形式应为“should+动词原形”，且should可以省略，encourage与主语“more people from all walks of life”之间为被动关系，所以此处应为should be encouraged，且should可以省略。故填(should) be encouraged。

7．（2024高三下·全国·专题练习）My husband is always talking about the economy, but I’d rather he  (focus) more on our children’s education. (所给词的适当形式填空)

【答案】focused

【详解】考查虚拟语气。句意：我丈夫总是谈论经济，但我宁愿他多关注一下我们孩子的教育。分析句子结构可知，此处应为“would rather+从句”结构，从句中的谓语动词通常使用虚拟语气，根据并列句的谓语动词is always talking可知，此处表示的是现在的情况，所以谓语动词应使用一般过去时，focus与句子主语he之间为主动关系。故填focused。

8．（23-24高三上·内蒙古赤峰·阶段练习）Kate suggested that not onlyI go to the party but also give a performance at the ball. (用适当的词填空)

【答案】should

【详解】考查（should）do虚拟语气和部分倒装。句意：凯特建议我不仅要去参加晚会，还要在舞会上表演。动词suggest意为“建议”，其后的宾语从句中应用（should）do虚拟语气，从句中not only位于句首，所以句子应用部分倒装。故填should。

9．（2023高三·全国·专题练习）“  it were not for tennis, I would still be helping out my family with farm work back at home,” Wang said. (用适当的词填空)

【答案】If

【详解】考查条件状语从句。句意：“如果不是打网球，我可能还在家里帮家人做农活”，王说。分析句子可知，此处为if引导的条件状语从句用虚拟语气，表示与现在的事实相反，首字母大写。故填If。

10．（2023高三·全国·专题练习）I am sure I would have lost him if I  (continue) dancing.（所给词的适当形式填空）

【答案】had continued

【详解】考查虚拟语气。句意：我相信如果我继续跳舞的话，我会失去他的。根据主句would have lost him可知是虚拟语气，且表示对过去事情的相反，故从句谓语用had +过去分词。故填had continued。

11．（23-24高三上·黑龙江哈尔滨·期中）If motorists  (avoid) speeding on highways, there would not be more traffic accidents reported. (所给词的适当形式填空)

【答案】avoided

【详解】考查虚拟语气。句意：如果驾驶者在高速公路上避免超速行驶，就不会有更多的被报道的交通事故了。分析句子可知，此处为if引导虚拟语气句型中从句谓语动词的填入，结合句意以及主句动词would not be可知，此处应为对现在情况的假设，所以从句动词为一般过去时。故填avoided。

（2024·浙江金华·二模）阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Short-form videos, which gained popularity on the Chinese platform Douyin, have given rise to a new trend in entertainment: ultra-short (超短) dramas.     12     (tailor) to our fast-paced lifestyles, ultra-short dramas are far more likely to attract people to try them out than traditional television series. In the past, committing     13     a show meant investing upwards of 40 minutes, but with ultra-short dramas, only a few minutes is enough for     14     taste.

Despite the initial success of ultra-short dramas, Chinese authorities     15     (tighten) regulations and intensifying monitoring on them. Currently, most of these ultra-short dramas revolve around clichéd (陈词滥调的) romantic plots, often     16     (feature) a wealthy individual getting together with a poor person. This narrative trend bears the potential     17     (shape) young minds’ perceptions of reality and their approaches to real-life challenges.

What’s equally concerning is     18     ultra-short dramas are designed to catch the viewers’ attention with bite-sized runtimes. In a world dominated by smartphones,     19     attention spans are already declining, frequent     20     (expose) to ultra-short videos can only worsen the issue.

It’s natural for us to seek entertainment. But it’s also worth pausing to consider the consequences      21      diving into ultra-short dramas.

【答案】

12．Tailored    13．to    14．a    15．are tightening    16．featuring    17．to shape    18．that    19．where    20．exposure    21．before/of

【导语】这是一篇议论文。文章讨论了一种新的娱乐趋势“超短剧”的有利因素和不利因素。

12．考查非谓语动词。句意：为了适应我们快节奏的生活方式，超短剧比传统电视剧更有可能吸引人们去尝试。分析可知，此处为非谓语，动词tailor“使适应”和主语之间是被动关系，故用其过去分词作状语。句首字母大写，故填Tailored。

13．考查介词。句意：在过去，看一部剧意味着要花40分钟以上的时间，但对于超短剧来说，几分钟就足够了。commit to sth“投入某事”是固定搭配。故填to。

14．考查冠词。句意：同上。可数名词单数taste“体验，尝试”是泛指概念，应用不定冠词限定。taste以辅音音素开头，故填a。

15．考查时态。句意：尽管超短剧取得了初步成功，但中国当局正在收紧监管，加强对它们的监控。根据句意可知，此处描述现在正在进行的动作，用现在进行时。主谓一致，故填are tightening。

16．考查非谓语动词。句意：目前，这些超短剧大多围绕着老套的浪漫情节展开，通常的特点是一个富人和一个穷人在一起。分析可知，此处为非谓语，动词feature和主语之间是主动关系，用其现在分词作状语。故填featuring。

17．考查非谓语动词。句意：这种叙事趋势有可能塑造年轻人对现实的看法，以及他们应对现实挑战的方法。potential to do sth“做某事的潜力”是习惯用法，不定式作后置定语。故填to shape。

18．考查表语从句。句意：同样令人担忧的是，超短剧的设计目的是用简短的片长来吸引观众的注意力。分析可知，此处引导表语从句，从句中意义完整，应用没有实际意义的连接词that引导。故填that。

19．考查定语从句。句意：在一个由智能手机主导的世界里，人们的注意力持续时间已经在下降，频繁地观看超短视频只会让这个问题变得更糟。此处引导非限制性定语从句，先行词为world，从句中不缺少主语或宾语，应用关系副词where引导，作地点状语。故填where。

20．考查名词。句意：同上。根据句子结构可知，此处应用其名词exposure(不可数)作句子主语。故填exposure。

21．考查介词。句意：但也值得停下来考虑一下，一头扎进超短剧的后果（但在一头扎进超短剧之前，也值得停下来考虑一下后果）。根据句意可知，此处可用介词before“在……之前”构成介词短语作状语；也可用介词of“……的”，构成介词短语作后置定语。故填before/of。

 

三、阅读理解

（2024·浙江杭州·一模）Diana was out shopping in a busy department store after work one evening. Just five minutes before closing time, she heard a staff member saying, “someone is having a seizure (癫痫)”: Walking quickly towards the staff member, Diana saw a fellow shopper on the ground. She had fallen and was lying on the floor, jerking uncontrollably. A small group of people had gathered to help the woman and a staff member called an ambulance. Dian a knew that she could use what she had learned on her first aid course to help as well.

Knowing it was important to keep the woman safe, one of the employees brought over a staff jacket and they put it under the woman’s head so she wouldn’t injure herself. “The seizure probably lasted only a few minutes, but it seemed much longer while it was going on,” Diana said. “When the jerking stopped, a man helped turn the woman on to her side. I then tilted her head back to help her keep breathing. After the seizure, the woman seemed not to be able to understand what we were saying and couldn’t speak. Luckily, I had learned that this can happen after a seizure and it may take some time for people to get back to normal.”

“It was such a comfort when she very tentatively answered that she was OK. By this time, the ambulance was on its way, the store had closed for the night and the other shoppers who had helped at first had left.” “We all a-greed that the woman was in safe hands with the first aider and a nurse who had also stopped to help, so I started to make my way out of the store.”

“As I was leaving, one of the store’s employees said, ‘thank you for your kindness’”. “I was very touched by her words, and I told her that I’d learned first aid in case something like this ever happened, and now it had. Even though the incident left me feeling very shaken, I was glad I knew what to do to help.”

23．How did Diana feel after the incident?

A．Grateful.          B．Relieved.                C．Anxious.                D．Regretful.

24．What can we learn from the last two paragraphs?

A．Diana stayed to help when the ambulance arrived.

B．The woman could not answer their questions because of pain.

C．It was essential to learn some knowledge of first aid.

D．The employee was too frightened to offer a helping hand.

25．Which proverb can be applied to Diana’s actions in this situation?

A．Actions speak louder than words.          B．Constant dropping water wears the stone.

C．A friend in need is a friend indeed.        D．Where there is a will, there is a way.
