【知识要点】
虚拟语气
一、语气的定义和种类1.语气(mood)
语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度。
2.语气的种类
1)陈述语气：表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。如：
There are two sides to every question.每个问题都有两个方面。
Were you busy all day yesterday?昨天一整天你都很忙吗？
How good a teacher she is! 她是多好的一位老师啊！
2)祈使语气：表示说话人对对方的请求或命令。如：
Never be late again! 再也不要迟到了。
Don’t forget to turn off the light.别忘了关灯。
3)虚拟语气：表示动作或状态不是客观存在的事实，而是说话人的主观 愿望、假设或推测等。如：
If I were a bird, I could 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。
May you succeed! 祝您成功！
二、简单句中的虚拟语气
1.情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌、或委婉的语气，常用于日常会话中。如：
Would you be kind enough to show me the way to the post office？
请你告诉我去邮局的路好吗？
It
2.表祝愿
1)常用“may+动词原形”表示“祝愿，但愿”，此时may须置于句首（多用于正式文体中）如：May good luck be yours! 祝你好运！
May you do even better! 祝你取得更大成就！
May you have a good time. 祝愿你玩得痛快。
May the friendship between us last long. 祝愿我们的友情天长地久。
May you be happy. (注意be) 祝你幸福。
2)用动词原形，如： Long live the people! 人民万岁！
“God bless you,”said the priest.牧师说：“愿上帝保佑你！”
Have a good journey! 祝愿你旅途愉快！
3.表示强烈愿望（该类型虚拟语气谓语仅用动词原形，第三人称单数也不加“s”）
4.表命令
1)命令虚拟语气只能用在第二人称(you)，而且通常省略主语(也就是you)。
2)句子尾通常加上感叹号：！
3)虚拟语气动词用一般现在时态(Simple Present)，如：work, be, go
4)否定形式的命令语气，可用助动词do，加上not。
Do not work so hard. (do not 表示否定的虚拟语气) 别工作那么卖力。
5.在一些习惯表达中，如：
You’d better set off now.你最好现在就出发。
I’d rather not tell you the secret.我情愿不告诉你这个秘密。
三、名词性从句中的虚拟语气
1.宾语从句中的虚拟语气
1)在动词wish后的宾语从句中的虚拟语气
在动词wish后的宾语从句中的虚拟语气，常省去宾语从句的引导词that。
①对现在情况的虚拟（与现在的事实相反）：从句用过去时或过去进行时(时间上是同时的)。其句子结构为：宾语从句的谓语be用were，实义动词用过去式。如：
I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。(事实上是不知道)
I wish it were spring in my hometown all the year around.但愿我的家乡四季如春。(事实上不可能)
I wish I were a bird.但愿我是只小鸟。(事实上不可能)
Now that he is in China, he wishes he understood Chinese.现在他在中国，他希望能懂得中文。(事实上并不懂)
②对过去情况的虚拟（和过去的事实相反）：
用wish表示对过去事情的遗憾。其句子结构为：宾语从句的谓语用过去完成时，或would, could, might+现在完成时。如：
I wish (that可省略，下同)I hadn’t wasted so much time. 我后悔不该浪费这么多时间。(事实上已浪费了)
He wishes he hadn’t lost the chance. 他真希望没有失去机会。(其实已失去)
③对将来情况的虚拟(表示将来的主观愿望)： 从句动词“would/should/could/might+动词原形”(时间上较后)(请注意：主句和从句的主语不相同)。用wish表示对将来事情的愿望。如I wish it would stop raining.(虚拟动词would+动词原形stop) 我希望雨能停止。(事实上雨还在下着呢)
I wish you would be quiet.(would + be) 我希望你安静一些。(事实上那家伙还在吵着呢)
You wished she would arrive the next day.(would + arrive) 你希望她第二天会到。(事实上她还没到)
注意： ① 如果将wish改为过去式wished, 其后that 从句中的动词形式不变。如：
I wished I hadn’t spent so much money. 我要是那时没有花掉那么多钱就好了。
②如果that 从句中用would, 一般表示对现状不满或希望未来有所改变或请求。如：
I wish you would help me. 我希望你能帮我。
2)在表示建议、命令、要求、忠告等动词的后面的宾语从句中的虚拟语气 由于这些动词本身隐含说话者的主观意见，认为某事应该或不应该怎样，这些词语后面的that从句应用虚拟语气，且均以should+动词原形表示这种语气，但事实上“should”常被省略，故此从句中谓语动词用原形，常用的此类动词有：
表示“要求”的：ask, desire, request, demand, require, beg
表示“提议、劝告、建议”的：move, propose, suggest, recommend, advise, vote
表示“决定、命令”的：decide, order
表示“主张”的：maintain, urge
表示“同意、坚持”的：consent, insist 如：
When I suggested that he try shaving cream, he said, “The razor and water do the job.”
当我建议他用刮胡膏时，他说“剃刀和水就行了”。
He pursued various theories for several days until I suggested we take the toy apart to see how it did work.
他费了几天功夫寻找理论根据，直到我建议拆开看看它是如何转动的。
One can suggest that students should spend two or three years in an English speaking country.
我们建议学生应在说英语的国家待上两三年。
在表示命令、建议、要求等一类动词后面的从句中虚拟语气很普遍，其结构如：
order, suggest, propose, require, demand, request, insist, command, insist +... (should) do
I suggest that we (should) hold a meeting next week. 我建议我们下周开个会
注意：在insist 后的从句中, 如果是坚持自己, 用陈述语气, 坚持别人做什么事情, 用虚拟语气。
She insists that she is right. 她坚持说她是对的。
She insisted that I should finish the work at once.
她一再坚持我应该马上完成这项工作。
或者说，suggest, insist不表示建议或坚持要某人做某事时，即它们用于其本意暗示、表明、坚持认为时，宾语从句用陈述语气。
判断改错:
(错)Your pale face suggests that you (should) be ill.
(对)Your pale face suggests that you are ill. (错)I insisted that you (should) be wrong.
(对) I insisted that you were wrong.
3)在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中的虚拟语气。
在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇、怀疑、不满等。
I never thought that he should be such a brave young soldier.
我们从来没想到他是个如此勇敢的小战士。
4)would rather，would sooner，had rather， would (just) as soon ，would prefer之后的宾语从句中的虚拟语气 would rather, would sooner, had rather, would (just) as soon，would prefer（希望）也用来表达主观愿望，它们之后的宾语从句中需用虚拟语气。谓语动词用过去时表示现在或将来，用过去完成时表示与过去事实相反。表示“宁愿做什么”或“对过去做的事的懊悔”。 The manager would rather his daughter did not work in the same office.
经理宁愿她女儿不与他在同一间办公室工作。
To be frank，I’d rather you were not involved in the case.坦率地说，我希望你不要卷入这件事。
I’d rather you didn’t make any comment on the issue for the time being.
我倒希望你暂时先不要就此事发表意见。
注意：
①若某人愿自己做某事，would rather后用动词原形
I would rather stay at home today.今天我愿待在家里。②would rather...than...中用动词原形
I would rather stay at home than go out today. 今天我想待在家里而不想外出。
5)“had hoped”后的宾语从句中的虚拟语气
用“had hoped”表示原来希望做到而实际上未能实现的事情，其宾语从句的谓语用“would+动词原形”。
I had hoped that she would go to the
我原本希望她到美国去念书并留在那，但她说她喜欢留在中国。
2.主语从句中的虚拟语气
1)“It is (was)+形容词（或过去分词）+that...”结构中的虚拟语气
在It is (was)+形容词（或过去分词）+that...结构中，使用某些表示愿望、建议、请求、命令、可能、适当、较好、迫切、紧近、重要等形容词后的主语从句的谓语也用虚拟语气。其表达形式为should ＋动词原形或省略should直接用动词原形（美国英语中省去should）
常用的形容词：natural (自然的), appropriate (适当的),advisable (合适的), preferable (更可取的), better (更好的)，necessary (必须的), important (重要的), imperative (急需的), essential (本质的), vital (必不可少的)，probable (很可能的), possible (可能的) desirable (极好的)，advisable（合理的），compulsory（必须的），crucial（紧急的），incre
常用的过去分词(Past Participle): required (需要的), demanded (要求), requested (被请求), desired (要求)，suggested (建议), recommended (推荐)，orderd (命令) 如：
It is essential that these application forms be sent back as early as possible.
这些申请表应尽早地寄回，这是很重要的。
It is vital that enough money be collected to fund the project.重要的是募集足够的钱，为这个项目提供资金。
注意：在上述所列形容词后面用that引出的宾语从句中，谓语动词也要用虚拟语气。
I don’t think it advisable that Tom be assigned to the job since he has no experience.
汤姆缺乏经验，指派他做这项工作我认为是不恰当的。
2）在It is ＋名词＋that...的主语从句中的虚拟语气
在It is ＋名词＋that的主语从句中，常用虚拟语气，表示建议、命令、请求、道歉、怀疑、惊奇等。这类名词有：advice，decision，desire，demand，idea，motion，order，pity，preference，proposal，recommendation，requirement，resolution，shame，suggestion，surprise，wish，wonder等。如：
It is my proposal that he be sent to study further abroad.我建议派他去国外深造。
3.虚拟语气用在表语从句或同位语从句中
当某些表示建议、请求、命令等主观意向的名词作主语时，其后的表语从句或同位语从句需用虚拟语气，其表达形式为should ＋动词原形或直接用动词原形。这类名词常见的有： demand (要求), desire (请求),requirement (要求)，advice (劝告), recommendation (建议),suggestion (建议)，order (命令)，necessity (必要地), preference (优先)，proposal (计划), plan (计划), idea (办法)， recommendation以及resolution等。如：
We are all for your proposal that the discussion be put off.
我们都赞成你提出的将讨论延期的建议。
The suggestion that the mayor present the prizes was accepted by everyone.
由市长颁发奖金的建议被每个人接受。
【考点诠释】
虚拟语气考点透析
考点一、虚拟语气的基本用法
1.与现在事实相反的虚拟语气，基本结构为：主语+动词的一般过去时（be动词用were）+其他成分+if+should/would/could...+动词原形+其他成分。例如：
①If it were not for the fact that she ______ sing，I would invite her to the party.
A.couldn’t B.shouldn’t C.can’t D.might not
解析 句意为：如果不是因为她不会唱歌的事实，我会邀请她来参加那次聚会的。that从句为同位语从句，描述的是事实，用陈述语气。正确答案为C。
2.与过去事实相反的虚拟语气，基本结构为：主语+动词的过去完成时+其他成分+if+should/would/could...+have done+其他成分。例如：
If the weather had been better，we could have had a picnic.But it ______ all day.
A.rained B.rains C.has rained D.is raining
If I ______ plan to do anything I want to，I’d like to go to Tibet and travel through as much of it as possible.
A.would B.could C.had to D.ought to
解析 句意为：如果我能够计划做我想做的事情，我想去西藏并且尽可能多玩一些地方。句子描述的是与将来事实相反的事情，所以正确答案为B。
考点二、含蓄虚拟条件句
这样的虚拟句不含有if从句，而是以but for/without/or/otherwise等引导的句子代替if从句，主句的谓语动词的形式与前面虚拟语气的基本用法相同。例如：
Thank you for all your
A.can manage B.could have managed
C.could managed D.can have managed
解析 由语境可知这里要表达的意思是：如果没有你们辛勤的工作，我们不可能处理好这件事。很显然，这是对过去发生的事实的虚拟，所以要用could have done，故应选B。
考点三、主从句时间不一致的虚拟条件句
在有些虚拟条件句中，主从句时间不一致，应根据不同情况区别对待。例如：
It’s hard for me to imagine what I would be doing today if I ______ in love，at the age of seven，with the Melinda Cox Library in my hometown.
A.wouldn’t have fallen B.had not fallen
C.should fall D.were to fall
解析 句意为：如果不是我在七岁时爱上家乡的Melinda Cox图书馆的话，很难想象今天的我会是什么样子。主句描述的是与现在事实相反的事情，从句描述的是与过去事实相反的事情。正确答案为B。
考点四、名词性从句中的虚拟语气
在含有表示坚持、建议、命令、要求等含义的名词性从句和在it做形式宾语或形式主语的复合句中，宾语补足语是necessary/strange/essential/natural/a pity/a shame等表示“惊奇、惋惜或者理应如此”等含义时，从句中的谓语动词需用“should+动词原形”，其中should可以省略。例如：
—Don’t you think it necessary that he ______ to Miami but to New Y
—I agree，but the problem is ______ he has refused to.
A.will not be sent；that B.not be sent；that
C.should not be sent；what D.should not send；what
具体说来其基本结构为：wish/if only/would rather+主语+动词一般过去时（表示与现在事实相反，其中be动词用were）/动词过去完成时（表示与过去事实相反）/would+动词原型（表示与将来事实相反）。例如：
Look at the trouble I’m in，if only I ______ your advice！
A.followed B.would follow
C.had followed D.should follow
解析 句意为：看我目前的困境，要是我听你的建议就好了。其描述的是与过去事实相反的事情。正确答案为C。

1. She might have been in time for the train, but she ______ late.
A. started B. has st
C. was to start D. had started
答案：A
解析：本题考查动词语气。might have done表示与过去事实相反，因此but后用一般过去时态表示实际发生的事。
2. I lost your cell phone number, otherwise, I _______ you long before.
A. had called B. have called
C. would have called D. should call
答案：C
解析：根据时间状语long before，可知这是对过去的假设，要是知道你的手机号码，我早就给你打电话了。
3.—It’s so near! We should have walked there.
—Yes, a taxi _______ necessary at all.
A. wasn’t B. isn’t
C. hadn’t been D. won’t be
答案：A
解析：这是一道根据情态动词+have done判断时态的题目。我们知道这个结构只可能有两种时态：过去时和现在完成时，对话内容是恍然发现目的地离得很近，所以本没必要打车，是对过去的虚拟，表示后悔的心情。真实的过去是坐了出租车的。
4. ________ it rain tomorrow, we would have to put off the sports meeting.
A. Would B. Should
C. Might D. If
答案：B
解析：if引导的虚拟将来的结构是：if...should/were to do...,...would do...这个句式可以倒装，变成：were...to do/should ...do...,...would do...。
5.________ the traffic jam, we would have arrived earlier.
A. In spite of B. Because of
C. But for D. Due to
答案：C
解析：这是一个含蓄的if虚拟条件句，相当于:If it hadn’t been for the traffic jam, we would have arrived earlier. but for=without,要不是。
6. Without your timely help, we _______ in big trouble that day.
A. had been B. would be
C. would have been D. were
答案：C
解析：本题同第五题。相当于if it hadn’t been for your timely help, we would have been in trouble that day.
7. It’s high time you _______ to make the decision yourself.
A. shall learn B. learn
C. learnt D. have learnt
答案： C
解析：It’s high time+从句表建议时要用were式虚拟语气，从句中用过去式。
8. If you ______ me earlier, you ________ sorry now.
A. had listened to; wouldn’t have been
B. were to listen to; shouldn’t have been
C. had listened to; wouldn’t beD. listened to; wouldn’t be
答案：C
解析：此题是一个混合虚拟语气题，从句是对过去的假设，所以根据if虚拟条件句的规则，要用过去完成时，而主句部分讲的是目前的情况所以要用would + do。 9.—I’m fe
—Well, I’d rather you _______ like a fish in the party.
A. didn’t drink B. hadn’t drunk
C. weren’t drinking D. not drink
A. did; set B. had done; should be set
C. do; be set D. had done; must be set
答案：B
解析：insist只有表示在建议的时候才用虚拟语气，如果是陈述事实的话就不用虚拟语气。所以他说he had done nothing是事实，不是要求。后面的句子才是要求，所以后面用“should do”式虚拟语气结构。
11. If only I ______ an umbrella! I was wet through.
A. took B. should take
C. had taken D. take
答案：C
解析：if only引导were式主观愿望虚拟语气句，“如果……就好了”根据规则，对过去虚拟用过去完成时。
