虚拟语气用法总结

虚拟语气分三种情况来掌握:

1、虚拟条件句。

2、名词性虚拟语气。

3、虚拟语气的其他用语。

一、虚拟条件句:

条件状语从句是非真实情况,在这种情况下要用虚拟语气。

1、条件从句与现在事实不一致,其句型为:If 主语+过去时,主语+should(could, would, 或might)+动词原形,如:

If I were you, I would study hard.

If it rained, I would not be here now.

2、条件从句与过去事实不一致,句型为:If 主语+had+过去分词,主语+should(could, would, 或might)+have+过去分词,如:

If the doctor had come last night, the boy would have saved.

If I had not studied hard, I would have failed in the exam last term.

3、条件从句与将来事实不一致,句型为:

If主语+should/wereto+do,主语+should(could…)+原形 do,如:

If it should rain tomorrow, we would stay at home.

If I were to go to the moon one day, I could see it with my own eyes.

If you missed the film to night, you would feel sorry.

注意问题:

1、If条件句中绝对不可出现“would”。

2、根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都是遵守上述句型。

3、在条件句中如果出现were, had, should可省去if,将主语与这些词倒装,例如:

Had the doctor come last night, the boy would have saved.

Were I to go to the moon one day, I would see it with my own eyes.

Should it rain tomorrow, we would stay at home.

二、名词性虚拟语气:

在表示命令、建议要求、惊叹时的名词性从句中需用虚拟语气,基本句型:主语+(should)+动词原形,如:

Mother insisted that John go to bed at 9 o’clock.(宾语从句)

We suggested that the meeting should not be held.

It was required that the crops should be harvested at once.(主语从句)

The suggestion that he be invited was rejected.(同位语从句)

That is their demand that their wages be increased.(表语从句)

注意:在这种句子中绝不出现“would”“must”“could”等。

三、虚拟语气在一些特殊词中的使用或含蓄条件句:

1、wish后的宾语从句:

与现在愿望不一致主语+过去时;

与过去愿望不一致主语+had+过去分词;

与未来愿望不一致主语+would(could)+原形。

I wish I were you.

I wish I had visited the white House when I was in the states.

I wish I met you tomorrow at the party.

2、It’s time句型:当It’s time后用that从句时应该为:主语+should+原形或主语+过去时,例如:

It’s time that you went to school. 或

It’s time that you should go to school.

3、If only引起的感叹句相当于“How I wish+宾语从句”

If only he could come! 他要能来就好了。

If only I had known the answer! 我要早知答案就好了。

4、would rather, as if(though)引导的句子也需使用虚拟,表示过去的情况用过去完成时,表示现在与将来的情况用过去时,如:

I’d rather you posted the letter right away.

I’d rather you had returned the book yesterday.

She loves the children as if they were hers.

Alan talked about Rome as if he had been there.

5、without, but, but for, otherwise引起的短语或句子常暗含着含蓄条件。

Without you, I would never know him.

But for your cooperation, we wouldn’t have done the work so well.

But that she was afraid, she would have said no.

I would be most glad to help you, but I’ am busy now.

I would have come to the party yesterday, but I was working.

I am busy now, otherwise I would do you the favor

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. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低),they wouldn’t go shopping. 附注: 虚拟语气,条件状从倒装 状语从句中,去掉if,提前were/ had/ should 如:If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外,without, but for, otherwise构成的条件状语从句中,也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及,publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.(表示可能性小)

虚拟语气的用法及专项练习题

虚拟语气的用法及专项练习题 虚拟语气表示一种假设的情况,或一种主观的愿望,即动词所表示的动作或状态并非事实,或不可能实现。英语虚拟语气的形式有下列几种: 一 .虚拟语气用于条件状语从句 注意:主句中的should通常用于第一人称,would可用于任何人称,同时也可根据意思用情态动词could,might等代替should,would。 1.与现在事实相反 (1) If had the time, John would make a trip to China to see the Great Wall. (2) If I were you, I would give up drinking immediately. 2.与过去事实相反 If I’d known that it was going to rain, I would never have gone for a walk in the country. 3.与将来事实相反

If it were to/should rain tomorrow,the meeting would be putoff. If you went there next time, you would see what I mean. 4.错综时间虚拟语气 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,动词的形式要根据它所表示的时间来调整。例如: If I were you, I would have gone home. If you had followed the doctor's advice, you would be quite all right now.(从句说的是过去,主句指的是现在。) If the weather had been more favorable ,the crops would be growing still better. 状语从句 1. 方式状语as if(as though) 如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用"had+过去分词";表示与将来事实相反,谓语动词用"would(might,could)+动词原形"。例如: (1) He looks at me as if I were mad. (2) He spoke English so fluently as if he had studied English in England.但as if(as though)后的从句也常用陈述语气,这是因为从句中的情况往往是可能发生的或可能被设想为真实的。例如:It looks as if our side is going to win. 2. 目的状语in order that,so that , lest ,for fear that等 从句谓语动词用" may/might,can/could)+动词原形"。例如: (1) She listened carefully in order that she might discover exactly what he wanted. (2) We hid behind some bushes for fear that passer-by should see us. 3. 连词引导的条件状语从句:

可用虚拟语气的用法总结

虚拟语气的用法总结 语气:语气是动词的一中形式,它表示说话人对某一行为或事情的看法和态度。 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 you, I should study English. 一.虚拟语气在条件从句的用法 条件句有两类,一类是真实条件句;一类是非真实条件句,也就是虚拟条件句。 如果假设的情况是有可能发生的,就是真实条件句,谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中,主句 If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if,采用局部倒装语序。把had /should/were 等动词(不包括行为动词)移到从句的句首。例如: Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致,这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三.含蓄条件句

虚拟语气完整用法

虚拟语气 一、用固定的情态动词表示的虚拟语气 1、 should +动词原形(有时省略should) (1)用在动词如advise, request, require, suggest, urge,demand, desire,command, insist, order, propose, recommend, 等后的宾语从句中。 例如: 1)They requested that we (should) send a invitation to their school、 2)He urged that he acquaint and apply the methods、 2、用在it is suggested,it has been decided, it is desired, it was proposed,it is required, it was ordered, it is necessary (essential, imperative, important, desirable) that等引出的主语从句中。 例如: 1)It is required that we (should) get everything done by tomorrow night、 2)It is imperative that the teachers (should) have a thorough knowledge of the subject they teach、 3、用在suggestion, motion, proposal, order, recommendation, plan, idea, requirement等引起的表语从句与同位语从句 例如:She drives her vessel carefully lest she should lost her way、 4.用在表示比拟的方式状语从句中 例如:He laughed as if he had never been happier before、 5.用在表示虚拟情况的定语从句中 例如:It is high time you stop bitting your child、 6.用在某些表示主观愿望的名词从句中 例1:I wish I were as tall as you、 例2:He insisted that we (should) catch up the first bus in the morning、 7.用在婉转的请求、建议、批评等句子中

虚拟语气用法小结及练习(附答案)

虚拟语气用法小结及相关练习(附答案) 一、虚拟语气在条件从句中的用法 条件句有两类,一类是真实条件句,一类是虚拟条件句。如果假设的情况是有可能发生的,就是真实条件何。在这种真实条件句中的谓语用陈述语气。如: If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚拟条件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天见到你,他会问你这件事的。(事实上他昨天没见到你,因此也未能问你这件事。) 1. 在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气。虚拟 2. 错综时间条件句:有时条件从句中的动作和主句中的动作发生的时间不一致(表示错综时间的虚拟语气),这时动词的形式要根据它所表示的时间加以调整。 If you had listened to the doctor, you would be all right now. 如果你当初听了医生 的话,身体现在就好了。(从句动作指过去,主句动作指现在) 3. 省略连词if (倒装)。在书面语中,如果虚拟条件从句中有were,had 或should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。 Should he come (If he should come), tell him to ring me up. Were I you (If I were you), I would not do it. Were I to meet him tomorrow (= if I were to met him tomorrow), I should ask him about it. 要是我明天见到他,我就会问他这件事的。

虚拟语气用法总结讲课稿

虚拟语气用法总结

虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达: a. 非真实的情景,不可能发生的事,即某种与事实相反或难以实现的情况,或说话人主观愿望。 b. 与客观事实相反地情景,即强制性虚拟语气,表示建议、命令、劝告这一类的意思上,表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的,其特点是主从句时态的不一致,而且一般有明显得标志。 二.虚拟语气的考点为: 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反:从句用一般过去时,主句的谓语用would (could, might) +动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反:从句用过去完成时,主句的谓语用would (could, might) +现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反:从句用should (were to,did) + 动词原形,主句的谓语用would (could, might) +动词原形 If it should/were to snow tomorrow, I would go skiing.

注意: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。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案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,主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.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。例如:条件句动作发生在过去,主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…,要是…多好”的语气表示与事实相反的情况,或表示将来不太可能实现的愿望。其宾语从句的动词形式为: He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形,其中should 经常被省略。这类动词包括: suggest, propose, recommend, demand, order, command, desire, require, insist,

虚拟语气的几种用法

虚拟语气的几种用法 1.错综时间条件句 虚拟语气通常用于含条件状语从句的主从复合句中。条件状语从句中表示与现在、过去或将来事实相反的虚拟语气比较容易掌握,但绝不可把它们当作一成不变的数学公式一样对待。就是说,不能只单纯背语法条条框框,而应充分理解句子锁定的语言环境。有时从句动作与主句动作发生的时间不一致。这时就要根据各自表示的时间概念加以调整。如: If he had taken my advice, he would be much better now.(从句与过去事实相反,主句与现在事实相反。) 2.含蓄条件句 有时假设的情况并不是以条件状语从句的形式表示出来,而是通过一个介词(如:without; butfor)引出的短语,一个连词(如:but; or; otherwise)引出的从句或其它方式来表示。如:Without your help, we couldn’t have finished the job in time.(Without your help=If you hadn’t helped us) He could have given you more help, but he was busy.(but he was busy=if he had not been busy) 3.倒装句 如从句中有were, had或should,则可以省去if, 并将were, had或should提前到句首,构成部分倒装。如: Were I to be young again, I would study medicine.(从句正常语序为:If I were to be young again) Had you not left so early, you might have missed the train.(从句正常语序为:If you had not left so early) 4.错综语气 有时从句用虚拟语气,主句却用陈述语气或祈使语气。如: If there should be an earthquake, what will you do﹖ (从句用虚拟语气,主句用陈述语气。) Ask her to leave a message if she should come.(从句用虚拟语气,主句用祈使语气。) 5.It is (high) time (that)句型 这个句型往往用“过去时”形式表示“现在”的动作,有时也用“should+动词原形”。如:It’s high time (that) we began to work. I think it’s time (that) you made up/should make up your mind. 6.主句中含有suggest, suggestion, propose, proposal, insist, order, demand, request等词时,从句谓语部分常用“(should)+动词原形”。如: She suggests that they (should) go there right away. Her suggestion is that they (should) go there right away.

虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句,表达的是说话人的遗憾后悔的语气,愿望以及建议,命令,要求等等的情感,往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后,有可能出现的情况。 虚拟语气的内容主要有三大模块,第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面:基本用法,各自为政,以及含蓄之美。 下表就是条件从句虚拟语气的基本用法: 通常,在上面表格里反映的是非真实条件句的虚拟语气模式,从句和主句的谓语动词时间是一致的,如果两者时间不一致,此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”,即从句和主句根据各自假设的时间不同,采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢?这就像是数学里的排列组合,一边有三种情况,交叉一搭配就出现了好多种情况。不管怎样,我们要遵循一个原则,就是“各自为政”。例如,从句是对过去情况的假设,而主句则是对现在情况的假设,那我们在使用时,从句就用过去完成式,而主句要用would/could do的形式。当然,也不是所有的AB配就是合理的,有时候在具体语境下,会出现矛盾的情况,这时我们就要结合要表达的意思来判断他们是对什么情况的假设,选择合适的形式。一般而言,主句的假设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现主句的现状。因此在此类的完成句子练习中,我们要特别提醒注意时间状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设,主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设,主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设,主句是对现在的假设) 5.

虚拟语气用法总结及详细解析

虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告,建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实,或难以实现的情况,甚至表达彻底相反的概念。此外,如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird,I would be able to 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。

If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪,我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话,我就会告诉她这件事的始末。 4、有时,虚拟条件句中,结果主句和条件从句的谓语动作若不是同时发生时,虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 ①从句的动作与过去事实相反,而主句的动作与现在或现在正在发生的事实不符。 If I had worked hard at school, I would be an engineer, too.如果我在学校学习刻苦的话,我现在也会成为一个工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话,我们现在就不会来这里了。 ②从句的动作与现在事实相反,而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话,我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话,他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时,if可以省略,这时条件从句要用倒装语序,即把were, should, had等词置于句首,这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话,我们就派他去。 Were she here, she would agree with us.如果她在这儿的话,她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话,我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句,否定词not应置于主语之后,而不能与were,should,had 等缩略成Weren't,Shouldn't,Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏,我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time,I would come. 假若我有时间,我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来,暗含在副词、介词短语、上下文或其他方式表示出来,这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中,如without…, but for…,otherwise(要不是因为)等 But for his help, we would be working now. (要不是他的帮助,我们还会在工作呢。

高中英语语法-虚拟语气全总结

虚拟语气在非真实条件句中

①错综时间条件句: 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,被称为错综时间条件句,动词的形式要根据它表示的时间作出相应的调整。如: If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首,变成倒装句式。如:If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会,我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点,你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话,我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如: What would you do with a million dollars? (=if you had a million dollars) 如果你有100万元,你会做什么? We couldn?t have finished the work ahead of time without your help. (=if we

虚拟语气的基本用法归纳

虚拟语气的基本用法归纳 今天我们从以下几个方面来掌握虚拟语气的基本用法。 一、虚拟语气的使用范围: 虚拟语气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。该语法主要用于if 条件状语从句中,也可用于主语从句、表语从句和宾语从句等。 二、虚拟语气的判断: 1. if 条件状语从句中虚拟语气的判断。if 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句,反之为非真实条件句,要用虚拟语气。其形式分为以下三种: (1) 与过去事实相反的假设。结构为:从句的谓语动词用“had + 过去分词”,主句用“should (would, could, might) + have + 过去分词”。例如: If it had not rained so hard yesterday, we could have played tennis. 如果昨天没有下大雨,我们就能玩网球了。(2) 与现在事实相反的假设。结构为:从句的谓语动词用过去式,系动词用were,主句的谓语用“should (would, could, might) + 动词原形”。例如: If I were in your position, I would marry her. 如果我是你,我就娶她为妻。

虚拟语气中的含蓄条件句常见用法总结

虚拟语气中的含蓄条件句常见用法先看一道高考题: ___ more attention ,the trees could have grown better . A.Given B.To give C.Giving D .Having given (答案是A ) 句中" ...the trees could have grown better" 是一个表达虚拟语气的句子。题中要求选择的是如何表达假设条件的形式。如果我们把这个句子用另一种形式"If they had been given more attentio n ,the trees could have grown better ." 来表示,就不难理解了。很多情况下,在表示假设的虚拟语气中,有时假设的条件并不以条件从句的形式表达,而是通过上下文或句中内在的逻辑关系,或用其它形式表达出来,我们称之为" 含蓄条件句" 。含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。现分述如下:一、介词短语常用来表示虚拟条件的介词有with ,without ,in ,under ,but for 等等,它们表示的虚拟条件都可以被if 从句替换。 ( 1 ) without ,with without 表示否定的条件,意为if ...not ;with 与without 意义相反,表示肯定的条件。如: Without air , there would be no living things .(without air = if there were no air)没有空气,便没有生物。 With her help (= If I had her help ),I would do the experiment well .假如有她帮助,我就可以把这个实验做好。 ( 2 ) under Under the leadership of a less experienced person ,the experiment would have failed .( u nder ...= If there had been the leadership of a less experienced person )假设在一个缺 少经验的人领导下进行实验,实验准会失败。 (3 ) in I would have lost my head in that position .( in that position = if I had been in that po sition )我处在那种情况下,是会丧失理智的。 ( 4 ) but for

高中英语虚拟语气用法小结

虚拟语气用法小结 白杨林 河南省社旗县第二高级中学 虚拟语气表示说话人所说的事或话不是事实,而是一种假设,愿望,怀疑或推测。它主要用于条件从句,让步从句和名词性从句中。 一、虚拟语气在条件句中的用法: 虚拟语气常用在条件句中,表假设的情况与事实相反或不太可能实现,这种句子称为虚拟条件句。可分为下列几种情况: (一)由if引导虚拟条件句。如:If I were you,I should study hard.如:If you had come here,you could have met my brother.这种句子的谓语动词一般分三种情况: 1、假设的条件与现在的事实相反,主从句的谓语动词应为:If主+动词过去式或were…,主+would/should/could/might+V、(原形)(主句中should 一般只用于第1人称)。如:If it were not for the smowy weather ,we would be all right. 例1、If I you,I would go with him to the party. A、was B、were C、had been D、will be 析:该句为if引导的条件句,从主语谓语看“would go”(是与现在事实相反),套用上边句型,从句谓语应为动词过去式,若是be动词应为were,所以该题答案应为B。 2、假设的条件与过去事实相反,其句子结构应为:If+主+had done…,主+would/could/should/mi ght+have done… 例2、 more careful,his ship would not have sunk. A、If the captain were B、Had the captain been C、Should the captain be D、If the captain would have been 析:该题题干部分有一谓语动词为would not have sunk,由此可知是对过去事情的虚拟,便可推出从句的谓语动词应为had done形式,再看选项,
