语法复习：

一、虚拟语气和倒装句

知识总结与归纳：

虚拟语气：是一种与事实（包括过去，现在或将来）完全相反的陈述，表示假设，愿望，怀疑，推测或后悔。虚拟语气主要用于条件从句，让步从句和名词性从句。

虚拟语气句型中常见的动词形式：

1. 动词过去式

2. had done

3. would/could/should/might do

4. would/could/should/might have done

5. were

（一）虚拟语气用在与过去事实相反的假设的条件句中：表示假设，后悔或推测。

句型结构：If +主语+had been/done….，主语

+should/could/might/would + have done….

1. If the illness had been diagnosed a day earlier, it might have made all different.

2. If she had told him about the danger, he would not have got hurt.

If +主语+should do

If +主语+动词过去式

（1）If we were to panic, we would not be able to help.

（2）If the little girl should take piano lessons, she would have less free time.

（3）If I were to live long enough to have a job, I would choose to be a doctor, helping these AIDS patients.

注意：虚拟条件句的从句中如果有助动词were; had或should 可以去掉if以后用倒装句语序。

例句：

① Had I not helped him, he would have failed in business.

② Should I be free, I would come .

③ Were she my daughter, I could suggest a different plan .

注意：有时候，主，从句所描述的时间范围不一致，则根据具体语境调整动词的形式。

例句：

① If he had caught the train, he would be here by now.

（四）虚拟语气在其他句型中的使用：

1. 用在与without, but for, but, otherwise短语连用的句型中：

例句：

The rescue arrived in time, otherwise They would have

been frozen to death.

2. 用在It’s time 句型中：It’s time that 主语+动词过去式……

③ I though it necessary that I should stay in the room till he came back.

（五）情态动词（should / ought to; could; needn’t; would like to等）+have done：表示“本来应该/能够/没必要/很愿意”

1. You could have told us earlier.

2. I ought to have bought that dictionary last week.

3. You ought not to have spent so much time in reading

novels.

4. We need not have been in a hurry to catch the train.

倒装句：倒装句是英语中常见的语法现象，他的使用一是出于语法结构的需要，再就是为了强调句中的某一部分。

（1）当否定副词never; hardly; seldom; nor; neither; little; few; not; not only 在句首，后面接助动词/be +主语……的倒装语序。

Never have I realized that water is so precious.

Not until we know more will we be able to improve the situation.

（4）as / so / neither / nor 在句首表示另一个人或另一种情况也是如此。后面接助动词/be +主语……的倒装语序。

Without international cooperation, developing countries cannot prosper, nor will sustainable development be possible.

A better understanding of the environment is necessary, as is the willingness to act.

（5）在以here; there; now; out; in; up; down; away 或表示地点的介词短语为句首后面接完全倒装结构（谓语+主语） Among the speakers was China’s then Premier Zhu Rongji, who stressed the need for equality and fairness in the world.

On a hill in front of them stood a great castle.

（6）倒装句在结果状语从句；让步状语从句；时间状语从句中

的使用：

① so / such ….that….（如此……以致于……）将so / such….部分置于句首：

So loudly did he speak that people upstairs could hear him.

②表示：“虽然……”：名词 / 形容词，副词 / 动词+as +主语+谓语……

Cold as it was, we went out .

Bravely as they fought, they had no chance of winning.

Child as he is, he knew what was the right thing to do.

③表示：“一……就……”：No sooner had …done …than +陈述句（过去时）

Hardly had…done…when+陈述句（过去时）

Hardly had she entered the house when she heard the dog barking.

No sooner had we started lunch than the door bell rang.

【典型例题】

1. You didn’t let me drive. If we ____ in turn, you ____ so tired.

A. drove; didn’t

get

B. drove; wouldn’t get

C. were driving; wouldn’t

get D. had driven; wouldn’t have got

答案：D

分析：本题考查虚拟条件句的运用。题干You didn’t let me drive.告诉我们后面的条件句是一个与过去事实相反的假设，有后悔，埋怨的意思。在这种条件句中主句用would have done，从句用had

done结

构。

2. ___ it rain tomorrow, we would have to put off the visit to the Yangpu Bridge.

A. Were

B.

Should C.

Would D. Will

答案：B

分析：本题考查虚拟条件句与倒装句的结合运用。句中时间状语tomorrow以及主句中的would表明该句是对明天天气情况的虚拟假设，表示将来的虚拟条件句的结构为If it should/ were to rain tomorrow。但是条件从句可以去掉连词if，从句用倒装句结构，即：Should it rain tomorrow.

3. The captain kept calm in the terrible storm, otherwise the accident ____.

A. couldn’t be

prevented B. mustn’t have prevented

C. wouldn’t have been prevented

D. shouldn’t prevent

答案：C

分析：本句是一个含蓄虚拟条件句。根据句义：船长在暴风雨中非常镇静，不然的话一场事故早就不可避免了。前半句描述了事实，而后半句则与过去的事实相反，虽然这部分没有以条件从句的形式出现，但是其内容包含在由连词but; otherwise连接的陈述句中。

4. When the pencil is partly in a glass of water, it look as

if it ____.

A. breaks

B. has

broken

C. were broken

D. had been broken

答案：C

分析：本题考查as if 后从句中的虚拟语气的运用。As if/though后面的从句根据句子的语境可以叙述为真实陈述，也可以是与现在或过去事实相反的虚拟陈述。本句描述的内容是与现在事实相反的虚拟陈述应当用一般过去

时。

5. Why didn’t you tell me there was no meeting today ?

I ___ all the way here through the heavy snow.

A. needn’t have

driven B. can’t have driven

C. mustn’t have

driven D. shouldn’t have driven

答案：A

分析：根据句意：你为什么不告诉我今天没有会？我本来没必要冒着大雪开车跑这么多路。 Needn’t have done表示本来没必要。

6. I was really anxious about you. You ___ home without

a word.

A. mustn’t

leave

B. shouldn’t have left

C. couldn’t have

left D. needn’t leave

答案：B

分析：根据句意：我真的很担心你，你真不应该一句话都不说就离开家。“离开家”已经发生了。Should have done正好表达了本句的意

思。

7. It is suggested that a

doctor immediately.

A. be sent

for

B. send for

C. is sent

for

D. should send for

答案：A

分析：It is suggested +that从句，从句中谓语动词用should do，或只用动词原形：a doctor与send for之间存在被动关系。

8. —Do you know Jim quarreled with his brother?

—I don’t know, ____.

A. nor don’t I

care

B. nor do I care

C. I don’t care,

neither. D. I don’t care also

答案：B

分析：not在句首表示另一种情况也是如此，句子要进行部分

倒装。Nor do I care“我也不在乎”。

9. Not until all the fish died in the river ____ how serious the pollution was.

A. did the villagers realize

B. the villagers realized

C. the villages did realize

D. didn’t the villagers realize

答案：A

分析：not until放在句首时，句子要进行部分倒装。

10. _ can you expect to get a pay rise.

A. With hard

work

B. Although hard work

C. Only with hard

work D. Now that he works hard

答案：C

分析：从谓语动词can you expect to可以看出，它使用了倒装句式，所以要选择能引导倒装的选项。“only+介词短语”引导状语且位于句首时，句子进行部分倒装。

一．虚拟语气

概念

[Subjunctive Mood]

中文译作"虚拟语气"。它是一种动词形式，表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。

语法结构

1.if结构（非真实条件句——表示的是假设的或实际可能性不大的情况）

与..事实相反 If从

句主句

过去 Had

done Would* have done

现

在 Were/did

Would* do

将来 Should

do/were/were to do Would* do

例句：If there hadn’t been much rain in spring, we would have had a good harvest now. [过去] If he smoked less, his cough might be well

soon. [现在]

If the lecturer should be late, you would have to make a speech first. [将来]

备注：

（1）上表中’*’，would都可转换为should、could、might。

（2) 如果为时间错综句的话，左右两栏可互相搭配，排列组合。

例句：

He would still be alive today if he hadn’t taken that drug.

[与现在事实相

反] [与过去事实相反]

(3) if可转换为其他形式

例句：Without your advice, our meeting wouldn’t have been so successfully. [过去]

（=>可转换为：If there hadn’t been your advice, we …）

Your notes are almost illegible (难以辨认的). Notes typed out would be a lot easier

to read.

[将来]

(=> 可转换为：If the notes had been typed out, it would be a lot easier to read.)

I should have gone to see Dr. Smith and he might have cured me of the disease.[过去]

(=> 可转换为：If he have gone to see Dr. Smith, he ..)

2、wish结构

与..事实相反

过去Had done

现在Were/did

将来Would

备注：可转换为其他形式。

例句：He talks as if (好像) he had done all the work himself. [过去]

I wish I were a bird.

I wish he handn' done that.

I wish I would be rich in the future.

3、should结构

从句中用“should + 动词原形”构成。而且should

可以省去。用于此结构的动词有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest,intend等。

例句：The teacher suggest he (should) read English aloud.

注意：当insist表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。

例句：The look on his face suggested that he was quite satisfied with what I had done for him.

He insisted that he was honest.

4、would rather ＋从句

在这种结构中，从句的谓语动词用过去形式表示虚拟。

例句：I would rather you did this instead of me.

5、主语从句中的虚拟语气

1）It be + 形容词 + that ．．．（should）．．．

用于该句型的形容词是：necessary, good, important, right, wrong, better, natural, proper, funny,

strange, surprising ．

一些名词也可以用于在该结构中。如：a pity， no wonder．．．．

2）It be + 过去分词 + that ．．．（should）．．．．

用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如：desired， suggested， requested，

ordered， proposed等。

3）It is time（about time， high time）that ．．．（过去式动词形式或should＋动词原形）．．．．

It is high time I went home now. = It is high

time I should go home now.

6、表语从句、同位语从句中的虚拟语气

在suggestion， proposal， order， plan， idea，advice， decision等需要有内涵的名词后面的表语从句、同

位语从句中，要使用虚拟语气。其谓语动词应用：should＋原形动词。另外连接从句的that不能省

略。

例：My suggestion is that we should go there at once.

What do you think of his proposal that we should put on a play at the English evening?

三、使用范围及判断

1、虚拟语气表示一种不能实现的假设。该语法主要用于if 条件状语从句。也可用于主语从句、表语从句、宾语从句等。

2、if条件状语从句中虚拟语气的判断

判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。

判断这个假设是与哪个事实相反。通常有三种情况：①与过去事实相反。②与现在事实相反。③与将来事实可能相反。

3、“后退一步法”

后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就是：

1）与过去事实相反，在从句中用过去完成时形式表示。

2）与现在事实相反，在从句中用过去一般时形式表示。

3）与将来事实可能相反，在从句中用过去将来时形式表示。

主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。

例：If I had come her yesterday, I would have seen him.

If I were a teacher, I would be strict with my students.

If it should snow tomorrow, they couldn’t go out.

四、注意事项

1.if条件句中如有were, should, had，可以省去if，并使用倒装语序。

2、在现代英语中if条件状与从句中的谓语动词如果是be 其过去形式一般用were。

3、wish 后面宾语从句中的虚拟语气，按“后退一步法”处理从句的谓语动词。注意：与哪个事实相反，不能以主句的时态为判断依据，而是根据从句的意义判断。

高中英语语法虚拟语气教学设计

高中英语语法虚拟语气 教学设计 集团档案编码：[YTTR-YTPT28-YTNTL98-UYTYNN08]

高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。

高中英语倒装句讲解以及习题

倒装句 一、定义：英语最基本的语序是主语在前，谓语动词在后。但有时由于句子结构的需要或表示强调，就要采用倒装形式。 Eg：The bus comes here. Here comes the bus. 车来了。 二、分类：全倒装:将谓语动词完全移到主语之前称为完全倒装， 半倒装:只将助动词或情态动词放到主语之前称为部分倒装。 Eg：Many years ago there lived an old man in the wooden house. 很多年前有一位老人住在那间木屋里。 Never have I been late for school this term. 这学期，我从来没上学迟到过。 三、全倒装：“五全”=有时表地方 经常与be/come/exist/fall/follow/go/remain/seem/stand（表示移动或动态的不及物动词连用） 或用表示类似“存在”观念的其他不及物动词如：live, stand, come, lie, flow, enter, rise 和appear等?㈠、“有”：在“there be”结构里 Eg：There is a box on the table. 桌子上面有一个盒子。 ?㈡、“时”：表示时间副词，如：now，then, Eg：Now comes your turn. 现在轮到你了。 ?㈢、“表”：表语放句子前，“表语＋系动词＋主语”的结构 Eg：Present at the party were Mr. Green and many other guests. 格林先生和其他的客人在这个聚会上。 Seated on the ground are a group of young men. 一群年轻人坐在了地上。 ?㈣、“地”：地点状语放在句首 Eg：In south of the river lies a small factory. 小工厂位于河的南方。 From the valley came a cry. 山谷传来一阵哭声。 ?㈤、“方”：表方位的副词here, there 或out, in, up, down, away, off等标志词放在句首

2020年高考英语新题型写作技巧八 强调倒装虚拟语气句型和丰富细节的手段

2020年高考英语写作新题型备考技巧 专题（八）强调倒装虚拟句型+丰富文章细节的手段 特殊句型是英语书面表达中的高级句式，其中强调句和倒装句是较为常见的特殊句型。而虚拟语气也是高中较难掌握的句型之一。它们的准确使用能够彰显考生的英语水平，提高写作档次。 一．重点突出的强调句型 （一）强调句的基本句式结构为：It is/was + 被强调部分+ that/who + 句子其他成分。它可以强调除谓语动词外的其它任何成分，如主语、宾语、状语等。在续写和概写中灵活运用强调句不仅能突出重点、增强表达，更能彰显考生的英语运用能力。 It is just the so-called inconvenience that displays the richness, delicacy and great fascination of Chinese culture with a history of thousands of years. (2019年浙江高考书面表达) 在写作中运用强调句型可以采取以下步骤： 1.在一个写好的句子中找出需要强调的成分，如主语、宾语、状语等； 2.根据句子的时态确定is或was； 3.然后把要强调的成分套进句式里，It is/was + 被强调部分+ that/who + 句子其他成分。 例：We created a harmonious atmosphere with sincerity and faithfulness. 如果我们要强调状语，即with sincerity and faithfulness，在确定好时态was后，把需要强调的部分放在it was后，that后放除强调外的剩余成分便得到： It was with sincerity and faithfulness that we created a harmonious atmosphere. （二）强调句常用句式 1. It is/was + 被强调的部分+ that/who + 句子其它成分 It is on the playground this Friday afternoon that a volleyball game will be held. (2019全国一卷书面 表达) It was because of their help that a disaster was avoided. (2017年浙江高考书面表达) 2. Is/was it + 被强调的部分+ that/who + 句子其它成分 Was it in the park that the children saw the strange green objects? 3.特殊疑问词+ is/was it + 被强调的部分+ 句子其它成分 When was it that you made up your mind to work as a volunteer teacher? 4.It is/was not until that + 句子其它成分

英语倒装句

英语倒装句(Inversion) 主语和谓语是句子的核心，它们之间有两种语序： 一是主语在谓语之前称为自然语序（Natural Order）； 二是主语在谓语之后则称为倒装语序（Inverted Order）。 而倒装语序中又有完全倒装（Full Inversion）和部分倒装（Partial Inversion）完全倒装（Full Inversion）:又称"全部倒装",是指将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。 部分倒装（Partial Inversion）:指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。 英语句子的倒装一是由于语法结构的需要而进行的倒装,二是由于修辞的需要而进行的倒装。 前一种情况,倒装是必须的,否则就会出现语法错误;后一种情况,倒装是选择性的,倒装与否只会产生表达效果上的差异。 语义解析 一、表示强调: 倒装句最突出、最常见的修辞效果就是强调,其表现形式如下: +状语或状语从句置于句首,句子用部分倒装。 例子: Only in this way can you solve this problem. 只有用这种方法,你才可以解决这个问题。 Only after he had spoken out the word did he realize he had made a big mistake.只有当他已经说出那个字后才意识到自己犯了个大错误。 2. hardly,in no way,little,scarcely,seldom,never,no more, no longer,not, not only, no sooner, not only … (but also),not until… 等具有否定意义的词或词组位于句首,句子用部分倒装。 例子: No sooner had I got home than it began to rain. 我刚到家就下起了雨。 Seldom do I go to work by bus. 我很少乘公共汽车上班。 Not until twelve o'clock did she go to bed last night . 她昨晚十二点才上床睡觉。 3. so / such...that结构中的so或such位于句首可以构成部分倒装句,表示强调so /such和that之间的部分。 例子: So unreasonable was his price that everybody startled. 他的要价太离谱,令每个人都瞠目结舌。 To such length did she go in rehearsal that the two actors walked out. 她的彩排进行得那么长,以致于那两个演员都走出去了。 以上各例都用倒装语序突出了句首成分,其语气较自然语序强烈,因而具有极佳的 修辞效果。 二、承上启下

英语虚拟语气语法归纳总结

虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it.

高中英语语法(虚拟语气)

Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形 与过去事实相反had + 过去分词 should/ would/could /might + have+过去分词 与将来事实相反1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。

大学英语四级语法考点透析

第一章动词的时与体(Tense & Aspect) 时（tense）是个语法范畴，它是表示时间区别的动词形式。英语动词只有“现在时”和“过去时”，而没有“将来时”（在英语中，表示“将来”手段多种多样，但没有一种独特的、能与“现在时”和“过去时”平起平坐的专一表示“将来”的动词形式----“将来时”）。 体（aspect）也是一个语法范畴，它表示动作或过程在一定时间内处于何种状态的动词形式。英语有进行体(progressive aspect)和完成体(perfective aspect)。进行体是由助动词be的一定形式加主动词的-ing 分词构成；完成体由助动词have的一定形式加主动词的-ed分词构成。 现在时和过去时既可以单独使用，也可以和进行体或完成体结合使用，也可以同时与完成体和进行体结合使用。这样，英语的限定动词词组便有8种时、体形式。它们分别是：一般现在时(simple present)、一般过去时(simple past)、现在进行体(present progressive)、过去进行体(past progressive)、现在完成体(present perfective)、过去完成体(past perfective)、现在完成进行体(present perfective progressive)、过去完成进行体(past perfective progressive)。在这一章中，我们单独挑出完成体来加以详述。 1．1 必须使用完成体的结构 1）It (This, This evening, yesterday...) is (was, will be) first (second, third...) time (day, month…)…结构中的分句，要求用完成体。 Is this the first time you've been to Beijing? This was the first time he had been to Beijing. This is the eighth month that I have been out of work.. This was the eighth month that I had been out of work. This is the second time that the goods produced by our factory have been shown in the International Exhibition. This was the second time that the goods produced by our factory had been shown in the International Exhibition. 2）在no sooner…than, hardly/barely/scarcely…when,等的句型中，主句要用过去完成体。 He had no sooner seen me than he left the room. No sooner had he seen me than he left the room. The helicopter had hardly landed when the waiting crowd ran toward it. Scarcely had I seen the lightning when I heard a clap of thunder. 3）将来完成体用来表示在将来某一时间以前已经完成或一直持续的动作。经常与before+将来时间或by+将来时间连用，也可与before或by the time引导的现在时的分句连用。 I will have finished all the work by the time you are back this evening. I am sure he will have left Paris by this time tomorrow. I hope we will have got all the information before you come tomorrow. By the time you get to New York, I _______for London. （2002年1月） A) would be leaving B) am leaving C) have already left D) shall have left 本题时间状语为by+将来时间，考察将来完成体用法，应选择D)。 By the time he arrives in Beijing, we ________here for two days.（2001年6月） A) have been staying B) have stayed C) shall stay D) will have stayed 将来完成体用来可以表示在将来某一时间以前一直持续的动作，本句话的意思是：我们将在这里呆两天，因此谓语动词用将来完成体，答案为D)。 1．2 现在完成体与现在完成进行体 现在完成进行体兼有现在完成体和现在进行体二者基本特点。由于它有现在完成体的特点，所以它

大学英语语法-虚拟语气

虚拟语气 1. 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) 2. He wishes he hadn't lost the chance. 他真希望没有失去机会。(其实已失去) 3. 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) Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。它仅有两个形式，即be型虚拟式和were型虚拟式。 Be型虚拟]----- be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。其主要用法如下： 1)用于表命令、决定、建议、坚持等词语之后的that分句中 这一用法又分三种情况： a)用在 decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句） 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。 He ordered that all the books be sent at once. He ordered that all the books be sent at once. we propose that somebody neutral take the chair. She insisted that she go to the south for her holiday. b)用在 advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。（主语从句） It is essential that all the facts be examined first. It was appropriate that thisi tax be abolished. I thousht it advisable that an armed guard stand in readiness. c)用在 decision,decree,demand,instruction,order,requirement,resolution等名词之后的that分句中。 The board has given instructions that the agent fly to Boston. We were faced with the demand that this tax be abolished. Their decision was that the school remain closed. 在这一用法中be型虚拟式能与“should+不定式”交替使用，也能与to-不定式交替使用。 He ordered that the books be sent at once . = He ordered that the books should be sent at onc. = He ordered that the books to be sent at once. 2）用于由if,though等引导的分句中.
