虚拟语态中时态交叉的题目怎么做

虚拟语气表示说话人说的话并不是事实,而是一种假设.其中拟所说的时态退一步,我想应该可以概括为以下几个：
首先是虚拟现在时,就是与现在事实相反的假设,那么从句中就要用过去时,主句用would等词加动词原形.来个例句吧,If I were you,I should do it now!
其次是虚拟过去时,就是与过去事实相反的假设,这个时候从句就要用过去完成时态had加过去分词,主句用could等词加过去分词.还是用一个句子比较形象的表示吧,If I had not went to that school,I might have 、、、、、
然后还有一种就是,从句和主句中的一个句子和现在事实相反,一个和过去事实相反.例如If you have done what the woman said,you could not have been wrong!
简言之呢,从句的时态和句中意思的时态往后推一个,句子情况是与现在事实相反,就用过去时,这里的过去时和与现在事实相反就存在一个退一步的过程!
这就是我的理解了,不知道你理解了没有,对照教材看看吧!

（⒈） 用if条件从句表示的虚拟条件,是虚拟条件最普通的方式.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 position 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 + have +过去分词,例如：If it had not rained so hard yesterday we could have 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 be 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
告诉你方法,自己搞答案

1）对过去情况的虚拟,句子用过去完成时.如：If only I had taken his advice!2）对现在情况的虚拟,句子用一般过去时/过去进行时.如果是be动词的话用were如：If only I were a billionaire!If only I were dreaming!3...

虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试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，是虚拟条件最普通的方式。 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 position 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 + have +过去分词，例如：If it had not rained so hard yesterday we could have 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 have 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have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，但频频出现在各类考试中出现，例如：If it had not rained so hard yesterday we could have played tennis.→Had it not rained so hard yesterday, we could have 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 telephone number; otherwise we would have telephoned 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引导的从句里，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 have hung you but the telephone 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, advice, insist, require, suggest, propose, order, recommend, 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, advisable等，例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly. ⒉ 在It's (high/about) time 之后的定语从句中需用虚拟语气。谓语动词用过去式，例如It is high time that you went to school ⒊ 虚拟语气在as if / as though 引导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 引导的状语从句中，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 advice. 同学您好，如果问题已解决，记得右上角采纳哦~~~您的采纳是对我的肯定~谢谢哦

If I got up earlier,I won't be late.

我倒觉得都可以,还帮你查了一下,例句是But for the rain we should have a pleasant journey.

表示于过去事实相反的假设.
句型：条件从句(if had+done) ,主句(would have done)
过去完成时 should(would) have+ 过去分词
例子:
If she had worked harder,she would have succeeded.
hope this can help!

这里不是虚拟语气.
这里是强调会攻击,让人小心的
如果碰到除非就是虚拟的话,那么如果 if 也就是虚拟了
if 假设的情况不是更重么?
要具体问题具体分析,不要死板的套书

由if引导的条件从句叫虚拟语态
有be动词要用were,口语可用was
建议你买一本张道真英语语法,上面很全!

If you hadn't told me ,I would know nothing about it .

B A
1、do you suggest 是插入语,但是suggest 会影响句子的谓语动词,should do ,should可以省略.
2、If were not for 对现在的虚拟,但一般会看成是固定句型,后面主句随着用对现在的虚拟的结构would do

If I had known,I would not ask you.

是的
1 表示与现在事实相反的情况：
从句：主语+过去时 　　主句：主语+should/would/could/might+do
就像您的B句中得结构
2.表示与过去事实相反的情况
从句：主语+had+done 　　主句：主语+should/would/could/might+have done　
A句是对“we haven't discussed it over the phone ”这一事实的虚拟,同时表达一种强烈的感情,“难道就不能电话里说?!”
这种用法的规则是：
虚拟条件句中,主、从句可以省略其中的一个,来表示说话人的一种强烈的感情.
①省略从句
He would have finished it.他本该完成了.
You could have passed this exam.你本该通过这次考试的.
②省略主句
If I were at home now.要是我现在在家里该多好啊.
If only I had got it.要是只有我得到它了该多好啊.

这句是对过去,而过句式是 If 主语+had＋过去分词,主语+would / should / could / might + have +过去分词 例如：If I were in your position I would marry he

1 insist+从句时,从句谓语用（should）+ v原形.should可省略.
2 答案应为D,主句虚拟将来,应该用would be.
3 答案应为A,从句和主句都虚拟过去.从句退一格用过去完成时,主句用would（should）+ 现在完成时.
虚拟语气分为从句和主句,从句和主句又各自分为虚拟过去,虚拟现在,虚拟将来三种情况.语法书上有各情况的表格,一目了然,可以去看下.
insist属于词法的特殊情况,类似的有表示建议、命令、请求的几个词---advice,demand,suggest,etc.
我确定我的解释是正确的.

1.主语从句
在主语从句中用以表示惊奇、惋惜、理应如此等意,其谓语用should +动词原形,should 在口语中可省略.主要用于以下三种结构：1)Itis necessary/important/natural / strange/essential /advisable/desirable/urgent …+that...如：It is necessary that he (should) get everything ready by tomorrow evening.到明天晚上前把一切准备好是必要的.It is important that you (should ) read English aloud every morning.你们每天早上朗读英语很重要.2) It is a pity (a shame,no wonder...)+that...如：It is a pity that she (should )be so careless.她这么粗心真是遗憾.It is no wonder that they (should) go there by air.难怪他们要坐飞机到那里去.3) It is suggested( decided,ordered,requested,desired,demanded,required,proposed,recommended) that ...如：It is requested that that factory (should) stop polluting the river.要求那家工厂停止对那条河的污染.It is decided that the sports meet (should) be put off till next week.已决定运动会推迟到下星期.
2.宾语从句
1) 在表示命令、建议、劝告、欲望、要求、主张这一类动词后的宾语从句中,从句应用虚拟语气,其谓语用should+动词原形,should可省略,这类动词有suggest,insist,demand,request,desire,order,ask,advise,propose ,command,recommend,require等,如：The teacher insisted that we (should) use an English-English dictionary.老师坚持要我们使用英英词典.I suggest the invitation to the conference (should) be sent to Dr Baker.我建议给贝克博士发出出席的邀请.
表语从句
当表示间接的要求、建议、命令、决定、欲望、劝告、主张等名词作主语时,其表语从句用虚拟语气.这类名词有suggestion,proposal ,request,order,advice,idea,demand,recommendation等,其谓语用(should)＋动词原形.如：Our suggestion is that you (should) be the first to go.我们的建议是你应该先去.My idea is that he (should) do his homework first.我的想法是他先做作业.4.上述名词的同位语从句也用虚拟语气,其谓语用(should)＋动词原形.如：Do you know the order that you (should ) keep watch 你知道你该去放哨的命令吗?We all agreed to his suggestion that we (should ) go to Beijing for sightseeing.我们都同意他要我们去北京浏览的建议.

why not go and talk with him? if I recognized him,I would do.

I'm not him.不用he是因为动词(系动词be)后面应该用宾格,而he上主格,him是he的宾格,这句话中I是主格.

虚拟条件句本来是保持时态一致的,但也有例外：错综时间条件句.比如一例：
你昨天要是听了我的建议,你现在就会好了.在这句话中条件是过去的,但主句却是现在的,因此语法上有个规则：“各扫门前雪”,即分别按自己的规则办事,If you had followed my advice,you would be better now.因此你的问题也是这个道理,主句是现在的说法,故用wouldn't you be upset,意为如果你昨天输了比赛,你现在不会伤心吗?

If I were him
后面应该用宾格

虚拟语态
一、虚拟语态的几种固定句式
1.I wish.(一定用虚拟)
1）I wish i were you
2)I wish that she were here with me
2、as if./as though 好象 (不一定用虚拟,要看说话的语境``)
1）He speaks as if he were an American.(如果他真的是美国人就不用虚拟了`)
2）He looks as if nothing had happened.
3、if I did/were.I would.
1)If I were you,I wouldn't do that
2)If it were to snow tomorrow,they would not go out
.(用were to 和were的区别是were to 是对将来的虚拟,
用were是对现在的虚拟`详见二、虚拟语态的几种形式```)
二、虚拟语态的几种形式
1、对现在的虚拟：（直接用动词的过去时.）
if I did /were.i would.
2、对将来的虚拟：if ..were to..I would.= if ..did...I would.
(此项与对现在的虚拟相同,但对现在的虚拟不用were to.
要区别对将来的虚拟和对现在的虚拟``一般句子里面都有时间标志``)
(If it were to rain tomorrow,we would not go out.
=If it rained tomorow,we would not go out.)
3、对过去的虚拟 If I had done.I would have done.
(If I had know the answer,I would have told you.)
(至于If ..had been done ...would have done
前面的been只是因为是被动语态```所以要看句子的具体意思````)
另外.固定句型的补充.
要用虚拟语态的句子:
i would rather i could.(I would rather she could not come here)
if noly..(但愿.)
A:I will go to Korean next month.B:If only I could go with you
虚拟语态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,推测,命令,建议,要求等.
o(∩_∩)o...
三种基本结构：
1.与现在事实相反的假设：一般过去时（be用were),主句结构{ should(would)等+动词原型}
例如：If they were here ,they would help you.如果他们在这,
2.与过去事实相反的假设：过去完成时 主句结构：{should(would)等+have+过去分词}
例如：If he had come yesterday,i should(would)have told him about it.如果他昨天来的话,我会把这件事告诉他的.
3.表示对将来不大发生的是的假想.一般过去时,were+不定式,should+动词原形；主句结构：{should(would)+动词原形.
例如：If you succeeded ,everything would be all right.如果你将来成功了一切都会好的.

这里没有一个虚拟语气的句子.正确的形式应该是If I had (也可以用：should have或were to have)time,I would go with you.

虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试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,是虚拟条件最普通的方式.
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 position 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 + have +过去分词,例如：If it had not rained so hard yesterday we could have 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 have 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have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,但频频出现在各类考试中出现,例如：If it had not rained so hard yesterday we could have played tennis.→Had it not rained so hard yesterday, we could have 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 telephone number; otherwise we would have telephoned 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引导的从句里,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 have hung you but the telephone 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, advice, insist, require, suggest, propose, order, recommend, 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, advisable等,例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly.
⒉ 在It's (high/about) time 之后的定语从句中需用虚拟语气.谓语动词用过去式,例如It is high time that you went to school
⒊ 虚拟语气在as if / as though 引导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 引导的状语从句中,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 advice.

主句一般情况下符合语境,如果是做题的话,要注意从句的形式,但要注意有混合虚拟语气,混合虚拟语气中会有提示时态的词语如now、yesterday等,这时就要根据语境.
