if虚拟语气的三种时态是什么

虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。

if后可以接虚拟语气。

虚拟语气的三种时态_if虚拟语气的三种时态

（1）种是与现在事实相反，if从句谓语用过去式或者were。

（2）第二种是与过去事情相反，if从句谓语用过去完成时：had+过去分词。

（3）第三种是与将来事实相反，if从句谓语用动词过去式，should +动词原形，或were to+动词原形。

if双语例句

1.She gets very upset if I exclude her from anything

要是有什么事情我不让她参加，她会非常难过。

2.He asked if I had left with you, and I said no

他问我是否和你一块儿离开的，我说不是。

有时即便有可能达到那个标准，那也是非常困难。

4.If 但would rather 后没有主语则应使用零不定式.I could just make another all point about the weightlifters in the Olympics

请允许我就有关奥运会举重运动员的问题再补充一点。

5.I wonder if you'd be kind enough to give us some rmation, please? 请问您能不能给我们提供一些信息？

wish后面的从句的时态

Eg. It is a pity that he should be so careless. C) 在由for fear that, in case, lest 等的状语从句中,用 “ should + 动词原形” 表示 “惟恐”的意思. Eg. He handled the instrument with care for fear that it should be damaged. D) 在 “ It is (about/ high ) time + that (从句)” 中,谓语动词常用过去式表表示虚拟语气. Eg. It is high time that people learnt English. E) 在 “as if/ as though” 的状语从句中,谓语动词与wish的宾语从句的虚拟形式相同. Eg. He works with such enthusia as if he nr knew fatigue.

虚拟语气wish三种时态：表示对现在情况的虚拟：wish+主语+动词过去式；表示对过去情况的虚拟：wish+主语+had+过去分词；表示对将来情况的虚拟：wish+主语+would+动词原形。 扩展资料 虚拟语气wish三种时态

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对将来发生的事情表示祝愿或愿望：主语＋wish＋从句主语＋would(could,might)+动词原形

③对过去发生的事情If it were not for their , we should be in a very difficult ition.表示遗憾或后悔时：主语＋wish（that）＋从句主语＋would/couldhe/had＋过去分词

英语中的虚拟语气

If I had taken your a（过去），I should he no trouble with the work now（现在）．

/suggest/

command

/require

/request

/demond

insist如果翻译成坚持某种动作才用虚拟语气；翻译成坚持某种观点就不用虚拟语气。

例句：He

这个语句表示的是事实，因此在这个语句中不能使用虚拟语气。

suggest意为“建议”才用虚拟语气，意为“暗示”则不用虚拟语气。

3.

表情绪.观点的形容词或名词也要用虚拟语气.

如:necessary、important、imsible、natural、strange、wrong、better、a

pity等。

句型：It

+从句，从句的谓语动词都要用should+原型

或只用动作表示建议、要求、命令等的名词aise、idea、order、demand、plan、proal、suggestion、request等的表语从句和同位语从句，从句中的谓语动词用“（should） + 动词原形”。如：词过去式。

这些是比较常用的，如果还想知道的话可以再问

虚拟语气的基本形式共有七种。

1.动词原形：Long live the Communist Party of China!

2.动词的过去式（be的过去式用were):If you loved me,you would not say that.

3.had+过去分词：If we had left earlier,we would not he missed the train.

4.时态助动词should+动词原形：If you should see Tom,give him my best wishes.

5.时态助动词should+he+过去分词：It is strange that she should he done it.

6.时态助动词should（人称）和would(第二、三人称）+动词原形：（1)If I were you,I should take his a.(2)He said he would go if I went .

7.时态助动词should(人称）和would(第二、三人称）+he+过去分词(1)If father had not sent me,I should not he come.(2)You would not he seen her if it had not been for him.

你就理解成说话人的假设好了。

比如

if i were you ，如果我是你的话，（可是事实上我不可能是你）

if i could fly ，如果我能飞（可是我不能飞实际上）

所以都不是真的，叫做虚拟语气。

虚拟语气作用是什么 表达什么意思

If we had started earlier, we should not he missed the train.

虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。

do形式

应用条件

虚拟语气常在表示条件和结果的状语从句中。在表示与事实相反的虚拟语气时动词有三种时态：现在时，过去时，将来时，过去完成时，现在完成时。

在条件句中的应用：条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。

在什么情况下用虚拟语气?

在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或表示某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，而不是根据客观实际，就用虚拟语气。

supe的虚拟语气用法

虚拟语气 有些条件句是可能实现的,称为真实条件句. 虚拟语气是动词的一种特殊形式,用来表达说话人的意愿.请求,设想,等未能或不可能实现的事实,或说话人看来实现可能性很小的情况.做这类题时首先要弄清楚虚拟语气的各种句型,即由if的虚拟条件句,省略if的倒装形式,可跟虚拟语气的宾语从句,同位语从句,表语从did句的句型,以及表示祝愿或感叹的句子和由without, but for等介词的短语或句子. 四级对虚拟语气的测试主要涉及以下方面: 1). 主语从句,同位语从句中虚拟语气的用法. 2). 宾语从句中虚拟语气的用法,尤其是wish 虚拟语气结构的用法. 3). If条件句中虚拟语气的用法,应特别注意省略if的倒装结构是的重点. 4). would rather 等结构中虚拟语气的用法. 5). if only结构中虚拟语气的用法. 6). But, or, otherwise 等含蓄条件句的用法. 7). It’s time (that) 等结构中虚拟语气的用法. 1. 虚拟语气在虚拟条件句中的运用

(1)虚拟语气现在时. 用以表示与现在事实相反的假设或现在实现可能性不大的情况.

条件从句 主句

动词过去式(be多用were) Would/should/could/might + 动词原形

Eg. If I were a bird, I would fly to you.

(2) 虚拟语气过去式. 表示与过去事实完全相反的假设.

条件从句 主句

had + 过去分词 would/should/could/might + he +过去分词

Eg. If we had started earlier, we should not he missed the train.

If she hadn’t been ill, she might he come.

(3)虚拟语气将来式. 表与将来情形相反的假设或极少有可能实现的情况. 条件从句 主句

动词过去式或should +动词原形或were to +动词原形 would/should/could/might +动词原形

Eg. If Professor Li should he time tomorrow, we could ask him some questions.

If there should be no air, there would be no living things.

◆ 书面语中,上述(1),(2),(3)三种时态的虚拟句中,如果从句里含有should, had, were或其他助动词,则可将从属连词if省去,将助动词.情态动词.be或he放在句首形成部分倒装. Eg. Were he in your ition, he’d he done the same.

Had I had time, I would he done that yesterday.

Should he come tomorrow, I should give him the dictionary. (1) 错综时间虚拟句

通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式. P 116, 2

Eg. If I were you, I would he taken his a. (从句指现在, 主句指过去) If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在).

(2) 含蓄条件句 有时假设的情况并不以条件从句表示出来,二是暗含在上下文中,比如通过介词短语来表示. Eg. But for your a, I could not he done it so successfully.

The change could not he taken place without the open-door policy.

I was so busy then, Otherwise, I would he told him the answer.

(3) 虚拟语气在某些从句中的应用. A) 在wish, suggest, order, demand, proe, command, request, recommend, require, decide, insist, desire, urge等动词的宾语从句以及would rather /sooner 后要用 “ (should) +动词原形” 来表示愿望,建议, 命令,要求等; 由上述动词派生或转化的名词suggestion, proal, plan, motion, recommendation, demand, order, desire, request, requirement, insistence, a, decision , obligatory 义不容辞的, 必须的 等的同位语从句或表语从句中也要用相应的虚拟形式. Eg.

B) 在It is/was + 某些形容词 + that 从句的句型中,that从句中的谓语动词常用虚拟语气,即 “should + 动词原形”

这些形容词有: important, necessary, essential, imperative, natural, strange, aisable, desirable, sible, probable, astonishing,do) surprising, desired, suggested, requested, recommended, ordered, proed, decided, moved等.

“ should + 动词原形(或完成形式)” 可表示惊奇,遗憾,怀疑,不满等. ⅰ. 用于expect, beli, think, suspect 等动词的否定或疑问形式后的宾语从句中. Eg. I nr expected that the new apartment should be so all. ⅱ. 用于 “It is a pity, it is a shame, it is no wonder 等 + that” 等结构后的主语从句中.

He speaks English as though he were an American. F) 在 look, seem等动词后的 “as if / as though”从句中,当表示真实情况时,用陈述语气; 否则,用虚拟语气. Eg. It seems as if they know each other. (真实情况)

It seems as though it were already spring. (虚拟语气) G) 用在if only 引起的感叹句中. Eg. If only the driver didn’t drive so fast!

虚拟语气的的三种情况下主句从句各用什么时态并写一个例句

虚拟语气的的三种情况下主句从句各用什么时态并写一个例句 虚拟语气(Subjunctive Mood)这一语法项目是各类英语中心测试的重点之一.虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测.Ⅰ用以表示虚拟条件的虚拟语气 ⒈ 用if条件从句表示的虚拟条件,是虚拟条件普通的方式.① 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might +动词原形,例如：If I were in your ition I would marry her.② 虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had＋过去分词,主句用would / should / could / might + he +过去分词,例如：If it had not rained so hard yesterday we could he played tennis.③ 大多数的虚拟条件句属于上面三种情况的一种,但并不排除存在条件和后果中,一个和现在情况相反,另一个和过去情况相反,例如：If you had followed what the doctor said,you would not he been so painful now.这个句子在高中出现频率颇高.④ 但是,如果后果用了虚拟语气,而条件却用陈述语气,这种用法是错的.⒉ 除了表示虚假条件外,if从句还可以表示对将来的推测,由于是将来还没有发生的,所以谈不上是真实的还是虚假的,只能说这个事情发生的可能性有多大.一般情况下,可以用陈述语气的if从句来表示对一个未来事实的推测,这个事实是完全可能发生的.If从句的谓语形式用一般过去式或用were to / should +动词原形,主句用would / should /could/ might +动词原形,例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.（1996年1月四级第44题） ⒊ 有时可以把含有助动词、情态动词、be或he的虚拟条件句中的连词if 省去,而将had ,should,were 等词提到主语之前,即用倒装结构,这时候,如果出现not等否定词,否定词需放在主语后面.这种结构在口语中很少使用,但频频出现在中出现,例如：If it had not rained so hard yesterday we could he played tennis.→Had it not rained so hard yesterday,we could he played tennis.⒋ 大多数的虚拟条件通过上面所讲的两种方法表达,但在个别句子中也可以通过介词without和介词短语but for表达,副词otherwise等表达出来.例如：We didn't know his ephone number; otherwise we would he ephoned him.（1995年6月四级第46题）值得注意的是,包含but for的句子,谓语动词必定要用虚拟形式,但包含without等短语的句子,谓语动词未必一定要用虚拟语气.⒌ 有时虚拟条件不是明确地表达出来,而在蕴含在用but的从句里,于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句,例如I would he g you but the ephone was out of order.在这样的句子里,如果主句没有用虚拟语气,或者从句用了虚拟语气,都是错的.Ⅱ用在宾语从句中的虚拟语气 ⒈ 在表示愿望的动词wish后的宾语从句中,需用虚拟语气.（wish后的that 常省略）,根据主句时态,从句谓语时态相应退后一位,例如：How she wished his family could go with him.⒉ 在具有愿望、请求、建议、命令等主观意愿的动词(desire,demand,a,insist,require,suggest,proe,order,remend,decide …) 后的宾语从句中需用虚拟语气.谓语动词用(should) +动词原形.值得注意的是,如果宾语从句的动词是否定的,否定词not的位置应在动词之前,而不是动词之后.例如：The head nurse insisted that the patient not be move.另外,如suggest表达“暗示”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气,例如：Her pale face suggests that she is ill.或He insisted that he did not kill the boy.除此之外,上述动词也要求用虚拟式 ① 在It is+上述动词的过去分词,其后所跟的主语从句中,如It is suggested that pupils wear school uniforms.② 在上述动词相应的名词形式作主语+连系动词,其后的表语从句中,例如His suggestion was that classed be re-scheduled.③ 在对上述动词相应的名词进行解释的同位语从句中,如：The workers raised the demand that their pay be increased to cope with the inflation.⒊ would （had）rather ,would sooner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.谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反,例如：I would rather he went right now.

过去的虚拟语气的主句和从句分别要用什么时态, 虚拟语气，主句和从句的时态是用什么时态？为什么

虚拟语气，从句用过去式，主句would这样的词+动词原形。另外一种，从句用过去完成时，主句用would+现在完成时。就这么简单看就行。

谁能简洁告诉我虚拟语气的三种时态的主从句的时态结

1. 对现在的虚拟结构：if+主语+动词动词过去时，主语+should/would+动词原形 should不可以省略

2. 对过去的虚拟结构：if+主语+had+过去分词，主语+should/would+he+动词过去时

3. 对将来的虚拟结构：if+主语+should+动词原形（were to+动词原形），主语+would/should+动词原形。

纯条件虚拟语气，主句用什么时态

虚拟语气(Subjunctive Mood)这一语法项目是各类英语中心测试的重点之一.虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测.

Ⅰ用以表示虚拟条件的虚拟语气

⒈ 用if条件从句表示的虚拟条件,是虚拟条件普通的方式.

① 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might 动词原形,例如：If I were in your ition I would marry her.

② 虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had＋过去分词,主句用would / should / could / might he 过去分词,例如：If it had not rained so hard yesterday we could he played tennis.

③ 大多数的虚拟条件句属于上面三种情况的一种,但并不排除存在条件和后果中,一个和现在情况相反,另一个和过去情况相反,例如：If you had followed what the doctor said, you would not he been so painful now.这个句子在高中出现频率颇高.

④ 但是,如果后果用了虚拟语气,而条件却用陈述语气,这种用法是错的.

⒉ 除了表示虚假条件外,if从句还可以表示对将来的推测,由于是将来还没有发生的,所以谈不上是真实的还是虚假的,只能说这个事情发生的可能性有多大.一般情况下,可以用陈述语气的if从句来表示对一个未来事实的推测,这个事实是完全可能发生的.If从句的谓语形式用一般过去式或用were to / should 动词原形,主句用would / should /could/ might 动词原形,例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.（1996年1月四级第44题）

⒊ 有时可以把含有助动词、情态动词、be或he的虚拟条件句中的连词if 省去,而将had , should, were 等词提到主语之前,即用倒装结构,这时候,如果出现not等否定词,否定词需放在主语后面.这种结构在口语中很少使用,但频频出现在中出现,例如：If it had not rained so hard yesterday we could he played tennis.→Had it not rained so hard yesterday, we could he played tennis.

⒋ 大多数的虚拟条件通过上面所讲的两种方法表达,但在个别句子中也可以通过介词without和介词短语but for表达,副词otherwise等表达出来.例如：We didn't know his ephone number; otherwise we would he ephoned him.（1995年6月四级第46题）值得注意的是,包含but for的句子,谓语动词必定要用虚拟形式,但包含without等短语的句子,谓语动词未必一定要用虚拟语气.

⒌ 有时虚拟条件不是明确地表达出来,而在蕴含在用but的从句里,于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句,例如I would he g you but the ephone was out of order.在这样的句子里,如果主句没有用虚拟语气,或者从句用了虚拟语气,都是错的.

Ⅱ用在宾语从句中的虚拟语气

⒈ 在表示愿望的动词wish后的宾语从句中,需用虚拟语气.（wish后的that 常省略）,根据主句时态,从句谓语时态相应退后一位,例如：How she wished his family could go with him.

⒉ 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, a, insist, require, suggest, proe, order, remend, decide …) 后的宾语从句中需用虚拟语气.谓语动词用(should) 动词原形.值得注意的是,如果宾语从句的动词是否定的,否定词not的位置应在动词之前,而不是动词之后.例如：The head nurse insisted that the patient not be move.另外,如suggest表达“暗示”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气,例如：Her pale face suggests that she is ill.或He insisted that he did not kill the boy.

除此之外,上述动词也要求用虚拟式

① 在It is 上述动词的过去分词,其后所跟的主语从句中,如It is suggested that pupils wear school uniforms.

② 在上述动词相应的名词形式作主语 连系动词,其后的表语从句中,例如His suggestion was that classed be re-scheduled.

③ 在对上述动词相应的名词进行解释的同位语从句中,如：The workers raised the demand that their pay be increased to cope with the inflation.

⒊ would （had）rather , would sooner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.谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反,例如：I would rather he went right now.

Ⅲ其他形式的过去完成时：should(would)he+ 过去分词虚拟语气

⒈ it is necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary, important, essential, imperative, urgent, preferable, vital, aisable等,例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce ry single word correctly.

⒊ 虚拟语气在as if / as though 的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式.例如：He felt as if he alone were responsible for what had happened. 表示过去想象中的动作或情况,谓语动词用过去完成式.

⒋ 在lest 的状语从句中,谓语动词多用虚拟语气,(should ) 动词原形.例如： The mad man was put in the soft-padded cell lest he injure himself.（1998年1月四级第38题）

⒌ 在if only 引起的感叹句中需用虚拟语气.谓语动词用过去式或过去完成式.例如： Look at the terrible situation I am in! if only I had followed your a.

if 从句用过去时，主句用什么时态？（真实条件句，不是虚拟语气）

虚拟情况下，这时就应该用过去将来式了。

eg: If I were you, I would choose not to go.

象你说的情况的话就应该用一般过去式了。

虚拟语气将来时中从句与主句的时态和结构？

if (did/were to do/should do), 主语 would do .

如：if I were you,I would go abroad.

虚拟语气的具体用法

It was a pity (a shame, no wonder, etc.)that you should be so careless.

1.概念

虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。

2.在条件句中的应用

条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。

真实条件句

真实条件句用于陈述语气，假设的情况可能发生，其中if是“如果”的意思。

时态关系

一般现在时：shall/willorder/ + 动词原形

注意：

1）在真实条件句中，主句不能用be going to表示将来，该用shall, will.

2）表示真理时，主句谓语动词便不用shall (will) +动词原形，而直接用一般现在时的动词形式。

非真实条件句

时态：可以表示过去，现在和将来的情况。它的基本特点是时态退后。

a.同现在事实相反的假设。

一般过去时：should(would)+动词原形

If they were here, they would you.

b.表示于过去事实相反的假设。

If she had worked harder, she would he succeeded.

The r would not he been burnt if you had been more careful.

If my lawyer had been here last Saturday, he would he prnted me from going.

If he had come yesterday, I should / would he told him about it.

含义：He did not come yesterday, so I did not l him about it.

If he had not been ill and missed many classes, he would he made greater progress.

含义： He was ill and missed many lessons, so he did not make greater progress.

c.表示对将来的假想

一般过去时：should+动词原形/were+不定式/would+动词原形/should+ 动词原形

If you succeeded, rything would be all right.

If you should succeed, rything would be all right.

If you were to succeed, rything would be all right.

混合条件句

主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。

If you had asked him yesterday, you would know what to do now.

（从句与过去事实相反，主句与现在事实相反。）

If it had rained last night (过去), it would be very cold today (现在).

虚拟条件句的倒装

虚拟条件句的从句部分如果含有were、should、或had可将if省略，再把were、should或had移到从句句首，实行倒装。

Were they here now, they could us. = If they were here now, they could us.

Had you come earlier, you would he met him. = If you had come earlier, you would he met him.

注意：

在虚拟语气的从句中，动词“be”的过去时态一律用“were”，不用was，即在从句中be用were代替。

If I were you, I would go to look for him. 如果我是你，就会去找他。

If he were here, rything would be all right. 如果他在这儿，一切都会好的。

典型例题

_____ to do the work, I should do it some other day.

A. If were I B. I wereC. Were ID. Was I

C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提

虚拟语气在状语从句中的运用除了可以表示条件外，还可以表示比较、结果、目的等。虚拟语气用于表示条件的状语从句中，一般称为虚拟条件句。根据时间的不同，虚拟条件句中谓语动词时态的变化可能有三种形式，即现在、过去和将来。

If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.（2001年 TEXT1）

这是一个含有条件状语从句的复合句。If it did是条件状语从句。主句中主语是it；谓语动词有两个，分别是would open up...和look for...。

这是一个与现在事实相反的虚拟语气，从句用一般过去时，主句用would+动词原形open up和look for。

参考译文：如果它能注意这个问题的话，它就会拓展其雇员多样化项目，而目前的项目只单纯考虑招收不同种族和性别的员工，去雇佣那些在世界观、价值观、教育背景及阶层方面各不相同的记者。

二、虚拟语气在名词性从句中的运用

虚拟语气除了用作状语从句中外，还可以用作主语从句、宾语从句、表语从句、同位语从句等名词性从中。

，虚拟语气在主语从句中的运用

当it作形式主语，后面用形容词作表语，即在it is + adj.这样的句型中，当描述主语的表语形容词是aisable，critical，crucial，desirable，essential，imperative，important，incredible，inevitable，necessary，recommend，strange，urgent等形容词时，主语从句的谓语动词多用虚拟语气，如果是现在时，谓语动词用should/would +动词原形（should/would经常省略）；如果是过去时，则用should/would + he done的形式。

It was inevitable that this primacy should he narrowed as other countries grew richer. Just as inevitably，the retreat from predominance proved painful.

这是一个含有主语从句的复合句。句首的It是形式主语，真正主语是that从句，该主语从句使用了虚拟语气should+完成时。（2000年 TEXT1）参考译文：随着其他日益富裕，美国的这一优势地位逐渐下降是不可避免的。惟其不可避免，从优势地位上退出愈发痛苦不堪。

第二，虚拟语气在宾语从句中的运用

表示“建议、请求、命令、要求”等主观意向的词（如：suggest、aise、assume、decide、demand、desire、insist、proe、order、recommend、require、suggest……），宾语从句时需用虚拟语气。虚拟语气中的格式很固定：谓语动词用should+动词原形，should可以省略。注意这种句型中的虚拟语气形式不受主句动词时态的影响。Theories concerning on the individual suggest that children engage in criminal behior because they were not sufficiently penalized for previous misdeeds or that they he learned criminal behior through interactions with others.（2004 CLOSE）

此句是个含有一个宾语从句、两个原因状语从句的复合句。suggest是主句谓语，Suggest后面的宾语从句中的谓语动词engage in前面省略了should.

参考译文：关于个体研究的理论认为，孩子们从事犯罪活动是因为以前他们做错事情时对他们的惩罚力度不够，或是因为他们通过与其他人的交往学会了犯罪。

第三，虚拟语气在同位语从句中的运用

Such behiour is regarded as “all too human”，with the underlying assumption that other animals would not be capable of this finely dloped sense of grievance. （2005年 TEXT1）

这是个含有同位语从句的复合句。that的同位语从句的谓语动词由would+动词原形be构成。

参考译文：这样的行为被认为“完全是人类的特点”，其潜在的含义是其它动物没有这种敏锐的委屈感。

第四，虚拟语气在表语从句中的运用

与同位语从句一样，若主语是某些特定动词的同根名词，要在它后面的表语从句要用虚拟式。

Another decision is wher the school should be one of the vast majority financed by the State or one of the very all but influential minority of private schools，though this cho is，of course，only ailable to the all number of those who can pay.

这是个含有表语从句的复合句。主语是another decision；谓语是is；wher……or……是表语从句，其中谓语动词由should＋动词原形be构成。参考译文：另一个要做出的决定是：应该选择一所占绝大多数的国立学校呢，还是选择一所数量虽小却有影响力的私立学校呢，当然，只有少数有支付能力的人才有这种选择的权利。

if only虚拟语气的三种时态是什么？

③提出过去的未发生的条件：主句：主语＋would/should/might/could he＋动词过去分词

1、表示与将来情况不同：if only＋ 从句主语＋would(could, might)+动词原形

eg：If only she would try again.

我希望她能再meet试一次

2、表示与现在情况不同：if only＋从句主语＋动词过去式

eg：If only I wasn’t going to London.

我希望我没去过伦敦.

3、表达与过去情况不同：if only＋从句主语＋would/could he/had＋过去分词

eg：If only you had come to my birthday party.

你要是来了我的生日晚会就好了。

if，wher这两个连接词均含“是否”之意。区别：

1、if作“是否”解时，多用于口语，引出宾语从句，不能直接跟or not连用。wher多用于书面语中，可与or或or not连用，除引出宾语从句外，还可引出主语从句、表语从句、同位语从句或与不定式连用。

2、if从句可以表示希望； 而wher从句单纯表示事实。

3、if不能用在介词之后的间接疑问句中； 而wher可以。

wouldrather虚拟语气的三种时态是什么?

is.......that

wouldrather虚拟语气的三种时态是倒退。从句要用虚拟语气，即从句中谓语动词用一般过去式，表示现在或将来的愿望，从句中谓语动词用过去完成市，表示对过去的愿望。wouldrather后接句子时，句子谓语习惯上要用虚拟语气。

(从句指过去，主句指现在)。如果过去几年里不努力工作，现在的情况就不会如此顺利了。时态的重要性

可以用进行时态来表达感彩。过去进行时可以用来强调信息。表达委婉的含义。能说明动作发生的时间。在语法里，时间或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式，将来式，通常也有与表示动作进行或终止的进行式和完成式等体貌。汉语没有时态这一说法，取而代之的是虚词，时间副词。比如我们说，我吃了。
