第二十八讲 虚拟语气（2）
(解析版)
黑龙江哈尔滨 邱尚瑛
虚拟语气在历年的高考试题中都占有较大比例，涉及范围较广，是高考试卷中非常重要语法项目，无论是在选择题、完型填空还是在阅读理解等各种题型中都可能出现，是历年高考中的必考内容，每年的命题形式也有所不同。教师在辅导学生进行虚拟语气复习的时候，首先要注重对其语言知识进行梳理，夯实基础知识，掌握核心内容，避免偏题、难题；避免有争议的怪题。教师需要把虚拟语气部分的语法现象从横向与纵向进行融会贯通，通过对语言知识的梳理提高学生借助语法知识进行阅读与写作能力。因此，教师要逐条列出学生出容易出现错误的问题，通过典型例句的讲解和巩固训练提高学生的语言应用能力。
由于虚拟语气部分的语法项目内容较多，而且对我们中国学生来说相对略有复杂。因此，虚拟语气部分的语法项目将分为两部分完成。本讲为第二部分，第一部分--虚拟语气的基本用法已经在第二十七讲中复习过了；在这一讲中，我们着重复习虚拟语气在各种不同情况下的应用。
I. 虚拟语气的不同用法
我们对虚拟语气的基本语法和用法已经在上一讲中进行了比较详细的复习，从三类语气的概述到虚拟语气的基本形式、虚拟条件句的用法以及与真实条件句的区别都做了比较详尽的总结。然而，在虚拟语气中，常常会有一些特殊句式与特殊的表达方法。比如：虚拟语气常会出现在目的状语中，出现在wish后面的宾语从句中，出现在表示坚持后面的宾语从句中，出现在表示命令、建议、要求、提议、投票、敦促、安排、希望、打算、指示等后面的宾语从句中，虚拟语气有时还会出现在定语从句中。在上面所提到的虚拟语气的情况中，有些最常用的已经在上一讲做过简单的介绍，这一讲中，我们要详细对以上情况进行梳理。
1. 虚拟语气在目的状语中的用法
1）在for fear that，in case，lest引导的从句中，若用虚拟语气时，从句谓语为（should）+ do；should可以省略，for fear that，in case，lest不能省略。
She examined the door again for fear that a thief (should) come in.

He started out earlier lest he (should) be late.
他早早地就出发了以防迟到。
2）在so that，in order that所引导的目的状语从句中，从句中的谓语为can / could / may / might / will / would /should + do。其中can / may / will / + do一般表示的是能实现的；could / might / would /should + do一般表示实现的可能性不太大。

6. 在would rather，had rather，would sooner等之后的宾语从句用虚拟语气
一般在would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气。其虚拟语气的结构为：

1. wish后的宾语从句需注意的问题：
表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；
表示与过去事实相反的愿望，从句谓语用would / could + have +过去分词或者过去完成时had done；
表示将来没有把握或不太可能实现的愿望用would (could) + 动词原形。
如果将wish改为过去式wished，后面that从句中动词形式不变（同wish）。
I wished I hadn't spent so much money.
但愿我没有花这么多钱。
I wished the prices would come down.
我希望物价能降下来。
I wished the train would come at that time.
我当时真希望火车会来。
2. 在insist，suggest后的宾语从句需注意的问题：
1）在insist的宾语从句中，从句谓语一般用虚拟语气，由“should+动词原形”构成。但是，insist后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别在于：谓语动词所表示的动作尚未发生或尚未成为事实，用虚拟语气；谓语动词所表示的动作已经发生或已经成为事实，要用陈述语气。
当insist意为“坚持某种动作”用虚拟语气；意为“坚持某种观点、某个事实”时不用虚拟语气。
He insisted that I had read his letter.
他坚持说我看过他的信。
He insisted that I should read his letter.
他坚持要我看他的信。
He insisted that he should have a look.
他坚持要查看。
He insists he is a student.
他坚持说他是个学生。（表示的是事实，因此不能使用虚拟语气。）
My family insisted that I should not give in, but stay and fight
家里人坚持认为我不应让步，而应该留下来继续抗争。（坚持动作，用虚拟语气）
2）与动词insist相似，动词suggest后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别也是：谓语动词所表示的情况尚未成为事实，用虚拟语气，此时suggest通常译为“建议”；谓语动词所表示的情况为既成事实，要用陈述语气，此时的suggest通常译为“表明”、“认为”（既：当suggest意为“建议”时要用虚拟语气，意为“暗示”或“表明”时不用虚拟语气）。
He suggested that we (should) stay for dinner.
他建议我们留下吃饭。（尚未成事实，虚拟语气）
What he said suggested that he was a cheat.
他说的话表明他是个骗子。（既成事实，陈述语气）
I suggested that you had a secret understanding with him.
我觉得你与他心照不宣。（既成事实，陈述语气）
His face suggests that he looks worried .
他的表情表明了他很担心。（这个句子本身是事实，因此它就没用虚拟语气。）
I suggest that we (should) have lunch right now.
我建议我们现在就吃午饭。（表示“建议”用虚拟语气。）
3. 在下面的情况一般要用“should + do”：
在一想要(desire；一宁愿 (prefer)；一坚持 (insist)；二命令 (order，command)；三建议 (advise，suggest，propose/recommend)；四要求 (demand，require，request，ask)中，无论主句谓语动词是何种时态，从句的谓语动词都用“should + do”，should可以省略。
He suggested that we (should) take the teacher's advice.
他建议我们采纳老师的建议。
He insisted that we (should) take the teacher's advice.
他坚持要我们采纳老师的建议
He demand that we (should) take the teacher's advice.
他要求我们采纳老师的建议。
He ordered that we (should) take the teacher's advice.
他命令我们采纳老师的建议。
4. It is/was time that +从句与It is/was the first time that +从句的区别
It is/was time that +从句是表示“早该做某事了”的意思，从句中的谓语动词用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语 + 动词的过去式或should + do。should不可省略，而且要优先使用动词过去式，即从句用虚拟过去式。
It is high time you should go to work.
你早该上班了。
It is high time that the old plane was scrapped.
这架旧飞机该报废了。
但是该句型略微调整成It is或was the first time that +从句（first也可能是其他序数词)，这个句子的谓语动词就不再采用上述形式。具体结构形式如下：
1）若主句是is，that后面句子的谓语动词部分用现在完成时（have/has done）；
2）若主句是was，that后面句子的谓语动词部分用过去完成时（had done)。
It is the first time that I have spoken to a foreigner.
这是我首次和一位外国人交谈。
For most students, we guess, it is the first time that they have been away from home.
我们猜测，对于大部分学生来说，这是他们第一次离家在外。

这是第一次她完全的生活在城市里。

那是我第一次当众挨批。

这是我第一次看到一部如此感人的电影。
He said that it was the first time that he had met such a strange person.
他说他还是第一次遇到这么奇怪的人。
It was the first time that I had seen such a beautiful place.
那是我第一次见到这么美的地方。
知识点一 wish后的宾语从句须注意的情况
例1：Ellen is a fantastic dancer. I wish I _________ as well as her.
A. dance B. will dance C. had danced D. danced
【答案】C
【解析】句意：艾伦是个出色的舞蹈演员，但愿我能够和她跳得一样好。I wish“但愿”后面接宾语从句用虚拟语气，和现在相反用一般过去时，答案C符合（注意：虚拟语气表示一些事与愿违或和事实不符的情况。有一些规则要记忆，如一些固定句型，还有要记住这些句型中动词的形式）。I wish“但愿”后面接宾语从句用虚拟语气，与现在相反用一般过去时，所以选择答案为C。
变式训练1：
1）I wish that you __________ such a bad headache because I am sure that you would have enjoyed the concert.
A. had not B. did not have had C. hadn’t had D. hadn’t have
2）How I wish I _________ to repair the watch! I only made it worse.
A. had tried B. hadn’t tried C. have tried D. didn’t try
知识点二 表示“坚持”、“命令”、“建议”等后的宾语从句
例2：The detective insisted that he ________ a look.
A. has B. has had C. (should) have D. have had
【答案】C
【解析】句意：警探坚持要查看。在表示“坚持”、“命令”、“建议”等后面的宾语从句中，谓语由“should + 动词原形”构成，should可以省略。故选择答案C。
变式训练2：
1）He insisted that I _________ with them.
A. will go B. would go C. will be going D. should go
2）She suggested that I _________ responsible for the arrangements.
A. had been B. was C. (should) be D. were
知识点三 由as if/as though引导的从句常会用到虚拟语气
例3：The girl is giving us a vivid description of the moon. It seems as if she ______ to the moon many times.
A. were B. was C. had been D. would be
【答案】C
【解析】句意：这个女孩正在给我们生动地描述月亮，就她好像已经去过月球很多次了似的。由as if（或者as though）引导的从句中，与事实相反的或者不可能实现的假设/不太可能发生的事情要用虚拟语气。该句中女孩好像多次去过月球这件事不太可能发生，所以用虚拟语气。根据虚拟语气的基本结构，答案A、B、C和D的时态都符合，但是虚拟语气中，be动词不用was，所以排除答案B；“好像去过很多次”是对与过去事实相反的描述，所以谓语动词用had +过去分词。故选择答案C。
变式训练3：
1）Liu Yong is now in a blue jacket. He looks as if he _______ an American boy now.
A. were B. was C. had been C. would be
2）The clouds are gathering. It looks as if it ________.

【答案】A
【解析】句意：她同意打开鞋盒，是到他知道鞋盒里是什么东西的时候了。It is/was time that +从句是表示“早该做某事了”的意思，从句中的谓语动词用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语 + 动词的过去式或should + do。should不可省略，而且要优先使用动词过去式，即从句用虚拟过去式。故选择答案A。
变式训练4：
1）It was the first time that I _________ a head of an office.
A. become B. will become C. have become D. had become
2）It is high time that we ________ trees there.
A. plan B. should plant C. are planning D. would plan
知识点五 would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望而使用虚拟语气
例5：I would rather she _________ me the bad news.
A. have not told B. didn’t told C. had not told D. would not told
【答案】C
【解析】句意：我真希望她没有告诉我这个不幸的消息啊！在would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气；其结构为：与现在和将来事实不相符用过去时；与过去事实不相符用had + done。故选择答案C。

第二十八讲 虚拟语气（2）
(解析版)
黑龙江哈尔滨 邱尚瑛
虚拟语气在历年的高考试题中都占有较大比例，涉及范围较广，是高考试卷中非常重要语法项目，无论是在选择题、完型填空还是在阅读理解等各种题型中都可能出现，是历年高考中的必考内容，每年的命题形式也有所不同。教师在辅导学生进行虚拟语气复习的时候，首先要注重对其语言知识进行梳理，夯实基础知识，掌握核心内容，避免偏题、难题；避免有争议的怪题。教师需要把虚拟语气部分的语法现象从横向与纵向进行融会贯通，通过对语言知识的梳理提高学生借助语法知识进行阅读与写作能力。因此，教师要逐条列出学生出容易出现错误的问题，通过典型例句的讲解和巩固训练提高学生的语言应用能力。
由于虚拟语气部分的语法项目内容较多，而且对我们中国学生来说相对略有复杂。因此，虚拟语气部分的语法项目将分为两部分完成。本讲为第二部分，第一部分--虚拟语气的基本用法已经在第二十七讲中复习过了；在这一讲中，我们着重复习虚拟语气在各种不同情况下的应用。
I. 虚拟语气的不同用法
我们对虚拟语气的基本语法和用法已经在上一讲中进行了比较详细的复习，从三类语气的概述到虚拟语气的基本形式、虚拟条件句的用法以及与真实条件句的区别都做了比较详尽的总结。然而，在虚拟语气中，常常会有一些特殊句式与特殊的表达方法。比如：虚拟语气常会出现在目的状语中，出现在wish后面的宾语从句中，出现在表示坚持后面的宾语从句中，出现在表示命令、建议、要求、提议、投票、敦促、安排、希望、打算、指示等后面的宾语从句中，虚拟语气有时还会出现在定语从句中。在上面所提到的虚拟语气的情况中，有些最常用的已经在上一讲做过简单的介绍，这一讲中，我们要详细对以上情况进行梳理。
1. 虚拟语气在目的状语中的用法
1）在for fear that，in case，lest引导的从句中，若用虚拟语气时，从句谓语为（should）+ do；should可以省略，for fear that，in case，lest不能省略。
She examined the door again for fear that a thief (should) come in.
她又把门检查了一遍，以防盗贼的进入。
He started out earlier lest he (should) be late.
他早早地就出发了以防迟到。
2）在so that，in order that所引导的目的状语从句中，从句中的谓语为can / could / may / might / will / would /should + do。其中can / may / will / + do一般表示的是能实现的；could / might / would /should + do一般表示实现的可能性不太大。
He goes closer to the speaker so that he can hear him clearer.

6. 在would rather，had rather，would sooner等之后的宾语从句用虚拟语气

1. wish后的宾语从句需注意的问题：
表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；
表示与过去事实相反的愿望，从句谓语用would / could + have +过去分词或者过去完成时had done；
表示将来没有把握或不太可能实现的愿望用would (could) + 动词原形。
如果将wish改为过去式wished，后面that从句中动词形式不变（同wish）。
I wished I hadn't spent so much money.
但愿我没有花这么多钱。
I wished the prices would come down.
我希望物价能降下来。
I wished the train would come at that time.
我当时真希望火车会来。
2. 在insist，suggest后的宾语从句需注意的问题：
1）在insist的宾语从句中，从句谓语一般用虚拟语气，由“should+动词原形”构成。但是，insist后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别在于：谓语动词所表示的动作尚未发生或尚未成为事实，用虚拟语气；谓语动词所表示的动作已经发生或已经成为事实，要用陈述语气。
当insist意为“坚持某种动作”用虚拟语气；意为“坚持某种观点、某个事实”时不用虚拟语气。
He insisted that I had read his letter.
他坚持说我看过他的信。
He insisted that I should read his letter.
他坚持要我看他的信。
He insisted that he should have a look.
他坚持要查看。
He insists he is a student.
他坚持说他是个学生。（表示的是事实，因此不能使用虚拟语气。）
My family insisted that I should not give in, but stay and fight
家里人坚持认为我不应让步，而应该留下来继续抗争。（坚持动作，用虚拟语气）
2）与动词insist相似，动词suggest后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别也是：谓语动词所表示的情况尚未成为事实，用虚拟语气，此时suggest通常译为“建议”；谓语动词所表示的情况为既成事实，要用陈述语气，此时的suggest通常译为“表明”、“认为”（既：当suggest意为“建议”时要用虚拟语气，意为“暗示”或“表明”时不用虚拟语气）。
He suggested that we (should) stay for dinner.
他建议我们留下吃饭。（尚未成事实，虚拟语气）
What he said suggested that he was a cheat.
他说的话表明他是个骗子。（既成事实，陈述语气）
I suggested that you had a secret understanding with him.
我觉得你与他心照不宣。（既成事实，陈述语气）
His face suggests that he looks worried .
他的表情表明了他很担心。（这个句子本身是事实，因此它就没用虚拟语气。）
I suggest that we (should) have lunch right now.
我建议我们现在就吃午饭。（表示“建议”用虚拟语气。）
3. 在下面的情况一般要用“should + do”：
在一想要(desire；一宁愿 (prefer)；一坚持 (insist)；二命令 (order，command)；三建议 (advise，suggest，propose/recommend)；四要求 (demand，require，request，ask)中，无论主句谓语动词是何种时态，从句的谓语动词都用“should + do”，should可以省略。
He suggested that we (should) take the teacher's advice.
他建议我们采纳老师的建议。
He insisted that we (should) take the teacher's advice.
他坚持要我们采纳老师的建议
He demand that we (should) take the teacher's advice.
他要求我们采纳老师的建议。
He ordered that we (should) take the teacher's advice.
他命令我们采纳老师的建议。
4. It is/was time that +从句与It is/was the first time that +从句的区别
It is/was time that +从句是表示“早该做某事了”的意思，从句中的谓语动词用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语 + 动词的过去式或should + do。should不可省略，而且要优先使用动词过去式，即从句用虚拟过去式。
It is high time you should go to work.
你早该上班了。
It is high time that the old plane was scrapped.
这架旧飞机该报废了。
但是该句型略微调整成It is或was the first time that +从句（first也可能是其他序数词)，这个句子的谓语动词就不再采用上述形式。具体结构形式如下：
1）若主句是is，that后面句子的谓语动词部分用现在完成时（have/has done）；
2）若主句是was，that后面句子的谓语动词部分用过去完成时（had done)。
It is the first time that I have spoken to a foreigner.
这是我首次和一位外国人交谈。
For most students, we guess, it is the first time that they have been away from home.
我们猜测，对于大部分学生来说，这是他们第一次离家在外。

他说他还是第一次遇到这么奇怪的人。
It was the first time that I had seen such a beautiful place.
那是我第一次见到这么美的地方。
知识点一 wish后的宾语从句须注意的情况
例1：Ellen is a fantastic dancer. I wish I _________ as well as her.
A. dance B. will dance C. had danced D. danced
【答案】C
【解析】句意：艾伦是个出色的舞蹈演员，但愿我能够和她跳得一样好。I wish“但愿”后面接宾语从句用虚拟语气，和现在相反用一般过去时，答案C符合（注意：虚拟语气表示一些事与愿违或和事实不符的情况。有一些规则要记忆，如一些固定句型，还有要记住这些句型中动词的形式）。I wish“但愿”后面接宾语从句用虚拟语气，与现在相反用一般过去时，所以选择答案为C。
变式训练1：
1）I wish that you __________ such a bad headache because I am sure that you would have enjoyed the concert.
A. had not B. did not have had C. hadn’t had D. hadn’t have
【答案】C
【解析】句意：我真希望你头痛得没有这么严重，因为我确信你会喜欢这场音乐会。事实上是头痛的很严重。wish引导宾语从句表示与事实相反的情况，或者表示将来不太可能实现的愿望，谓语动词要用虚拟语气。从该句主句的谓语动词（ would have enjoyed ）可以看出句子所表示的是与过去事实相反的假设，所以谓语动词用过去完成式。故选择C。
2）How I wish I _________ to repair the watch! I only made it worse.
A. had tried B. hadn’t tried C. have tried D. didn’t try
【答案】B
【解析】句意：我多么希望我没有尝试过修这块表啊！我只是让它变得更糟了。wish在这里引导宾语从句表示的是与事实相反的假设，事实上是修了这块表，而且把这块表修坏了。答案A所表示的是我希望我修理过，但是后面的句子告诉我们已经修坏了，所以答案A所表示的是事实，不符合wish引出的虚拟语气的句子结构。hadn’t tried to repair表示的是过去没有修理过，联系前面的wish可以分析出希望没有修理过；故选择答案B。
知识点二 表示“坚持”、“命令”、“建议”等后的宾语从句
例2：The detective insisted that he ________ a look.
A. has B. has had C. (should) have D. have had
【答案】C
【解析】句意：警探坚持要查看。在表示“坚持”、“命令”、“建议”等后面的宾语从句中，谓语由“should + 动词原形”构成，should可以省略。故选择答案C。
变式训练2：
1）He insisted that I _________ with them.
A. will go B. would go C. will be going D. should go
【答案】D
【解析】句意：他坚持要我同他们一起去。在表示“坚持”、“命令”、“建议”等后面的宾语从句中，谓语由“should + 动词原形”构成。故选择答案D。
2）She suggested that I _________ responsible for the arrangements.
A. had been B. was C. (should) be D. were
【答案】C
【解析】句意：她建议我来负责进行安排。动词suggest后接宾语从句时，除可用虚拟语气外，也可用陈述语气，两者的区别也是：谓语动词所表示的情况尚未成为事实，用虚拟语气，此时suggest通常译为“建议”。谓语动词所表示的情况为既成事实，要用陈述语气，此时的suggest通常译为“表明、认为”。当suggest意为“建议”时要用虚拟语气，意为“暗示、表明”时不用虚拟语气。该句子中的动作是表示建议，尚未成事实，用虚拟语气。故选择答案C。
知识点三 由as if/as though引导的从句常会用到虚拟语气
例3：The girl is giving us a vivid description of the moon. It seems as if she ______ to the moon many times.
A. were B. was C. had been D. would be
【答案】C
【解析】句意：这个女孩正在给我们生动地描述月亮，就她好像已经去过月球很多次了似的。由as if（或者as though）引导的从句中，与事实相反的或者不可能实现的假设/不太可能发生的事情要用虚拟语气。该句中女孩好像多次去过月球这件事不太可能发生，所以用虚拟语气。根据虚拟语气的基本结构，答案A、B、C和D的时态都符合，但是虚拟语气中，be动词不用was，所以排除答案B；“好像去过很多次”是对与过去事实相反的描述，所以谓语动词用had +过去分词。故选择答案C。
变式训练3：
1）Liu Yong is now in a blue jacket. He looks as if he _______ an American boy now.
A. were B. was C. had been C. would be
【答案】A
【解析】句意：刘勇现在穿着一件蓝色的夹克衫。他现在看起来好像是个美国男孩。由as if（或者as though）引导的从句常用虚拟语气。但是用虚拟语气，还是用陈述语气，需要根据具体情况而定。如果从句表示的意思与事实完全相反，或者纯粹是一种假设，通常用虚拟语气。而且在虚拟语气中，be动词用were。故选择答案A。
2）The clouds are gathering. It looks as if it ________.
A. might rain B. is going to rain C. had rained D. rained
【答案】B
【解析】句意：云在聚集。看来要下雨了。该句子所描述的是即将发生的事实，所以要注意：as if（或as though）引导的从句与事实相符的时候，从句要用陈述语气。故选择答案B。
知识点四 It is/was time that +从句与It is/was the first time that +从句的区别
例4：She agreed that it was high time that he _________ what was in the box.
should know B. knows C. known D. would know
【答案】A
【解析】句意：她同意打开鞋盒，是到他知道鞋盒里是什么东西的时候了。It is/was time that +从句是表示“早该做某事了”的意思，从句中的谓语动词用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语 + 动词的过去式或should + do。should不可省略，而且要优先使用动词过去式，即从句用虚拟过去式。故选择答案A。
变式训练4：
1）It was the first time that I _________ a head of an office.
A. become B. will become C. have become D. had become
【答案】D
【解析】句意：这是我第一次成为头部的一个办事处。该句型与It is (high / about) time that + 主语 + 动词的过去式或should + do不同，已经调整成It is或was the first time that +完整句子（first也可能是其他序数词)，这个句子谓语动词就不再采用例题4中的形式。当主句系动词用的是is，则that后面的句子的谓语动词部分用现在完成时（have/has done）：若主句用的是was，则that后面的句子的谓语动词部分用过去完成时（had done)。故选择答案D。
2）It is high time that we ________ trees there.
A. plan B. should plant C. are planning D. would plan
【答案】B
【解析】句意：是到我们在那儿种树的时候了。It is/was time that +从句是表示“早该做某事了”的意思，从句中的谓语动词用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语 + 动词的过去式或should + do。should不可省略，而且要优先使用动词过去式，即从句用虚拟过去式。故选择答案B。
知识点五 would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望而使用虚拟语气
例5：I would rather she _________ me the bad news.
A. have not told B. didn’t told C. had not told D. would not told
【答案】C
【解析】句意：我真希望她没有告诉我这个不幸的消息啊！在would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气；其结构为：与现在和将来事实不相符用过去时；与过去事实不相符用had + done。故选择答案C。
变式训练5：
1）I would rather I _________ to the theatre than stayed home night.
A. had gone B. have gone C. didn’t go C. would go
【答案】A
【解析】句意：我真希望昨天晚上去看了戏而不是呆在家里。在would rather，had rather，would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气；其结构为：与现在和将来事实不相符用过去时；与过去事实不相符用had + done。故选择答案A。
2）I ________ you had told me the truth.
A. will rather B. would rather C. have rather D. will sooner
【答案】B
【解析】句意：我倒想你本该把事实真相告诉我。would rather，had rather，would sooner都表示宁愿，宁可；但是它们略有一些差别。在它们之后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气。其结构为：与现在和将来事实不相符用过去时；与过去事实不相符用had + done。故选择答案为B。
一、选择题（Choose the best answer）
1. __________ hard, he would have passed the exam.
If he were to work B. Had he worked
C. Should he work D. Were he to work
【答案】B
【解析】句意：如果他努力学习，他就会通过考试了。这个句子也是一个带有省略形式的虚拟条件句，没有省略之前应该是If he had worked hard, he would have passed the exam. 当从句的谓语动词含有were，should，had时，if可以省略，这时从句要用倒装语序，即把were，should，had等词置于句首。故选择答案B。
2. I wish I _________ here then.
A. was B. had been C. were D. would be
【答案】D
【解析】句意：我多么希望那时候我会在这里。wish引导宾语从句表示与事实相反的情况，或者表示将来不太可能实现的愿望，谓语动词要用虚拟语气。该句子是对将来事情的假设，所以用would + be。故选择答案D。
3. She seems as if she _________ a great thing
A. does B. had done C. makes D. was doing
【答案】B
【解析】句意：她看起来好像做了一件大事。as if引导表语从句，一般是与事实相反的、或者不太可能实现的假设，所以从句的谓语要用虚拟语气；但是如果从句的假设可以实现或者即将成为事实，可以用陈述句语序。从该从句的句意看，她看上去好像做了一件大事，暗含着不是的意思，所以用虚拟语气。故选择B。
4. How I wish every family ________ a large house with a beautiful garden.
A. has B. had C. will have D. had had
【答案】B
【解析】句意：我多么希望每个家庭都有一座有漂亮花园的大房子。wish引导宾语从句表示与事实相反的情况，或者表示将来不太可能实现的愿望，谓语动词要用虚拟语气。该句子所表示的是与现在事实相反的假设，谓语动词用过去式。故答案为B。
5. We would rather our daughter ________ at home with us, but it is her choice, and she is not a child any longer.
A. would stay B. has stayed C. stayed D. stay
【答案】C
【解析】句意：我们宁愿我们的女儿和我们呆在家里，但这是她的选择，她不再是一个孩子了。would rather表示宁愿，宁可；其后的宾语从句常表示与客观事实不相符的一种愿望，所以使用虚拟语气。其结构为：与现在和将来事实不相符用过去时；与过去事实不相符用had + done。该句子是于现在事实不符合，所以用过去时态；故答案为C。
6. If I __________ it with my own eyes, I wouldn’t have believed it.
A. didn’t see B. weren’t seeing C. wouldn’t see D. hadn’t seen
【答案】D
【解析】句意：如果不是我亲眼看到，我不会相信。当有if引导时，首先要根据句意和句子结构判断是真实条件句还是虚拟条件句，如果符合虚拟的结构，就可以根据句子中的时间和语意判断应该用哪种虚拟语气。根据后半句wouldn’t have believed可以判断是对过去的虚拟。所以从句是if +主语 + had + done的形式。故选择答案D。
7. Without his wartime experiences, Hemingway____ his famous novel A Farewell to Arms.
A. didn’t write B. hadn’t written
C. wouldn’t write D. wouldn’t have written
【答案】D
【解析】句意：海明威没有他战时的经验，他就不可能写出著名小说《永别了，武器》。这是一个虚拟语气的句子，所表示的含义不是客观存在的事实，是对过去的虚拟猜测；根据without his wartime experience没有战时的经历，可知所表示是对于过去的否定猜测，所以主句用would have done，故选择答案D。
8. I wish I ______ at my sister’s wedding last Tuesday, but I was on a business trip in New York then.
A. will be B. would be C. have been D. had been
【答案】D
【解析】句意：上个周二我本希望参加我姐姐的婚礼，但那时我在纽约出差。这是由wish引导的宾语从句，从时间状语last Tuesday可以判断出wish用于对过去的事实表示一种不可能实现的愿望。表示与过去事实相反的愿望，从句用had + 过去分词，答案D符合。由wish引起的表示愿望的虚拟语气：① wish表示对现在的愿望时，从句谓语动词为过去式（be动词用were）；② wish表示对将来的愿望时，从句中谓语动词形式为：would，could，might + 动词原形；③ wish用于对过去的事实表示一种不可能实现的愿望时，从句中的谓语动词形式为had + 动词过去分词或could，would + have + 动词过去分词。故选择答案D。
9. We lost our way in that small village, otherwise we ________ more places of interest yesterday.
A. visited B. had visited C. would visit D. would have visited
【答案】D
【解析】句意：我们在那个小村庄迷路了，要不然我们昨天会参观更多的名胜古迹。虚拟语气可以通过副词otherwise等表达。该句子表示的是与过去事实相反的假设，主句用would have done。故选择答案D。
10. It is lucky we booked a room, or we _________ nowhere to stay now.
A. had B. had had C. would have D. would have had
【答案】C
【解析】句意：我们很幸运地订到了房间，否则的话，我们现在就会无处可去了。or引导含蓄虚拟条件句，or后面是主句，相当于if we hadn’t booked a room, we would have nowhere to stay now. 根据now可知，是对现在情况的假设，所以用would + 动词原形符合该句。本题考查含蓄虚拟语气和错综时间虚拟语气，由otherwise，or，without等引出的相反的情况被称为含蓄虚拟语气。or引出相反的情况，对过去虚拟，主句用would + have done，但是主句中有now，表示与现在相反，因此用would + 动词原形。故选择答案C。
11. It was suggested that he _________ the club activities.
A. would join B. has joined C. should join D. had joined
【答案】C
【解析】句意：有人提议他应该参加俱乐部的活动。用来表示建议、命令、要求、惊异和失望等的词后面的从句一般用虚拟语气，其形式为：(should) + 动词原形。suggested表示建议，故选择答案C。
12. It is essential that you _________ the voters’ hearts.
A. would win B. has wined C. win D. will win
【答案】C
【解析】句意：赢得选民的心是绝对必要的。用来表示建议、命令、要求、惊异和失望等的词后面的从句一般用虚拟语气，其形式为：(should) + 动词原形。常这样用的形容词有appropriate适当的advisable适当的，合理的better较好的desirable理想的essential精华的 imperative迫切的important重要的insistent坚持的natural自然的necessary必要的preferable优越的，较好的strange奇怪的urgent紧迫的vital极其重要的；故选择答案C。
13. The thief closed his eyes ________ he _________ dying.
A. as if；was B. though； would be
C. even；had been D.as if； were
【答案】D
【解析】句意：小偷闭上了眼睛，就好像要死了一样。从全句子看，小偷把眼睛闭上，好像要死去了一样，事实上不是真的。由as if（或者as though）引导的从句中，与事实相反的或者不可能实现的假设/不太可能发生的事情都要用虚拟语气。在所给答案中，先排除答案B和C；而答案A中的be动词错误，虚拟语气be动词用were；所以只有答案D符合。故选择答案D。
14. If I _________ you, I _________ travel abroad with them.
A. am；will B. were；would C. was；would D. were；will
【答案】B
【解析】句意：如果我是你，我会和他们一起出国旅游。这是一个虚拟条件句，因为我不可能是你，此处只是一个不可能实现的假设，因此要用虚拟语气。虚拟语气if从句要用过去时态，主句用would+动词原形；所以首先排除答案A和D；再看答案C的be动词用的是was，实际上应该用were，虚拟语气要求be动词都用were。
15. Without electricity, human life ____________ quite difficult today
A. is B. will be C. would have been D. would be
【答案】D
【解析】句意：如果没有电，今天的人类生活就会十分艰难。根据虚拟语气也可以通过介词without或者介词短语but for来表达，这个句子就是通过介词without引出的虚拟条件句。因为是虚拟语气，所以先排除答案A和B；再则，所表达的是于现在事实相反的假设，因此要用would be，而答案C表达的是与过去事实相反的假设。故选择答案D。
16. _________ the clouds, you would find the airplane in the sky easily.
Had it not been for B. If it were not
C. If it had not been for D. Were it not for
【答案】D
【解析】句意：如果不是因为有云，你会很容易找到天空中的飞机。该句子是一个含有省略形式的虚拟语气的句子，是省略if的倒装句。当从句的谓语动词含有were，should，had时，if可以省略，这时从句要用倒装语序，即把were，should，had等词置于句首。该句子是对现在事实相反的假设，所以排除答案A和D。答案D强调了找不到飞机的原因是因为天上有云；而答案的意思是如果天上不是云，显然表达不清。故选择答案D。
17. If my lawyer ________ here last Sunday, he ________ me from going.
A. had been, would have prevented B. had been, would prevent
C. were, prevent D. were, would have prevented
【答案】A
【解析】 句意：如果我的律师上星期天来过这里，他会阻止我去的。与过去事实相反的假设，从句是If+主语+had+done；主句是主语+ should / would / might / could + have done。故选择答案A。
18. The clouds are gathering. It looks as if it ________.
A. might rain B. is going to rain C. had rained D. rained
【答案】B
【解析】句意：云在聚集。看来要下雨了。该句子所描述的是即将发生的事实，所以要注意：as if（或as though）引导的从句与事实相符的时候，从句要用陈述语气。故选择答案B。
19. He ________ busy yesterday, or he ________ you with your experiment.
A. was；had helped B. was；would have helped
C. had been；would have helped D. were；would have helped
【答案】B
【解析】句意：他昨天很忙，否则他会帮你做实验的。or =otherwise，要不然的话……，后面与事实相反，事实是因为忙，没能帮上。or后面用虚拟语气来委婉表达自己的想法愿望，前面部分陈述昨天的事实，后面部分用虚拟语气表达对过去的愿望和想法，对过去的假设用would have done。故选择答案B。
20. We ________ last night, but we went to the cinema instead.
A. must have studied B. might study
C. would study D. would have studied
【答案】D
【解析】句意：我们昨晚本来可以学习的，但取而代之的是我们去看电影了。故有时虚拟条件不是明确地表达出来，而在蕴含在用but引导的从句里，这个句子就是蕴含在用but引导的从句里的虚拟语气；该句子所表达的是对过去发生事情的假设，故选择答案D。
二、句型训练（Choose the correct words to fill in the blanks）
1. If he _________，he would miss the train. (didn't hurry up；doesn't hurry up)
【答案】didn't hurry up
【解析】 从主句的谓语动词可以看出这是一个虚拟条件句，事实上因为他当时动作快，而赶上火车了。虚拟条件句的if从句的谓语动词用过去时态，从句用过去将来时态。（如果他没快点的话，他就会赶不上火车了。）
2. __________ it rain tomorrow, we would have to put off the visit to the Songhua Bridge.（Were；Should）
【答案】 Should
【解析】句意：这个句子在没有省略前应该是if it should rain tomorrow, we would have to put off the visit to the Songhua Bridge. 所表达的是明天很可能会下雨，我们只好推迟参观杨浦大桥这个活动。当从句的谓语动词含有were，should，had时，if可以省略，这时从句要用倒装语序，即把were，should，had等词置于句首。（如果明天下雨，我们就不得不推迟参观松花江大桥。）
3. ________ today, he would get there by Friday.（Were he to leave；Had he left）
【答案】 Were he to leave
【解析】句意：从主句的谓语动词可以看出这是一个与现在事实相反的假设，说明他今天不太可能出发。当从句的谓语动词含有were，should，had时，if可以省略，这时从句要用倒装语序，即把were，should，had等词置于句首。虚拟语气是were to do。（如果他今天出发，在星期五之前他就会到达那里。）
4. We ________ the difficulty together, but why didn't you tell me?
(could have faced；should face)
【答案】 could have faced
【解析】 该句子通过but可以分析出是一句隐含的虚拟语气，意思是如果你告诉我了，我们就会和你一起面对困难。事实上没有告诉我。（我们可以一起面对困难，但是你为什么不告诉我？）
5. Had you listened to the doctor, you ________ now.（would be all right；are all right）
【答案】 would be all right
【解析】 Had引出的含有虚拟语气的倒装句，从句表示的是与过去事实相反的情况，而主句强调的是现在的情况。（如果你听医生的话，你现在就会完全好了。）
6. Sorry, I am too busy now, if I ________ time, I would certainly go for an outing with you. (have；had )
【答案】 had

【答案】should come

10. Had they known what was coming next, they ________ second thoughts.（could have；might have had）
【答案】 might have had
【解析】 这个句子的if从句用的是省略形式，没省略之前的句子是：If they had known what was coming next, ... if从句的谓语动词是过去完成时态，所以主句用might have done。（如果他们知道接下来会发生什么，他们也许会重新考虑。）
