虚拟语气一直都被认为是英语学习中的一个难点,因此也便成为了各类考试的热点.现就虚拟语气的一些问题归纳如下,以帮助解决拟语气这个语法难点.
一、 动词wish后宾语从句中的虚拟语气
1． 用wish表示现在的祝愿和报歉.
其句子结构为：宾语从句的谓语be和were(was),实义动词用过去式.例：I wish the were at home this time.
2． 用wish表示对过去事情的遗憾.其句子结构为：宾语从句的谓语用过去完成时,或could+现在完成时.例：I wish I hadn' t hurt him so much.
3． 用wish表示对将来事情的愿望.其句子结构为宾语从句的谓语为would/could/might+动词原形.例：I wish I might be able to come tomorrow .
二、 用在一般虚拟条件句中的虚拟语气
（一） 表示与现在、过去、将来事实相反的假设
1． 与现在事实相反的假设.
其句子结构为：
从句：if+主语+动词的过去式（be变were）+其他
主句：主语+would(should, could, might)+动词原形+其他
例：If I were you, I would go with him.
2． 与过去事实相反的假设.
其句子结构为：
从句：If+主语+过去完成时+其他
主句：主语+should(would, could, might)+现在完成时+其他.例：If you had studied harder last term, you could have passed exam.
3．表示对将来事实实现的可能性不大的假设.
其句子结构为：
从句：If+主语+should (were to )+动词原形+其他
主句：主语+would (could, should, might)+动词原形
例：If he were to go tomorrow. He might tell you.
(二) 从句和主句要根据各自发所生的时间选用符合具体时间的虚拟语气形式
1． 从句表示过去,主句表示现在.
If they had stared the early morning yesterday, they would be here now.
2． 从句表示将来,主句表示过去.
If I were not to make a preparation for my experiment this afternoon, I would have gone to see the film with you last night.
3． 从句表示过去,主句表示将来.
If we hadn' t made adequate preparations, we shouldn' t dare to do the experiment next week.
4．从句表示将来,主句表示现在.
If we shouldn' t have an exam this afternoon. I would go
shopping now.
三、 可以引起与事实相反的方式状语从句,用虚拟语气 由as if、as though引起的与事实相反的句子,不论主句的谓语是现在时或者说过去时,其谓语表示的时间概念和句子结构,都基本上与wish后的宾语从句相同.例：
John pretends as if he didn' t know the thing at all, but in fact he knows it very well.(用过去式表示与现在事实相反的假设)
The old man looked at the picture, he felt as though he had gone back to time 20 years ago.（用过去完成式表示与过去相反的事实）
They talked and talked as if they would never meet again (would+动词原形,表示与将来事实相反)
四、在表示建议、命令、要求、忠告等动词的后面,其宾语从句的谓语用“should+动词原形”表示虚拟语气
常用的此类动词有：
表示“要求”的：ask, desire, request, demand, require, beg
表示“提议、劝告、建议”的：move, prpose, suggest, recommend, advise, vote
表示“决定、命令”的：decide, order
表示“主张”的：maintain, urge
表示“同意、坚持”的：consent, insist
例：The doctor suggested that he (should) try to lose his weight.
He insisted that we (should ) tell him the news.
上述动词的名词形式,demand, desire, requirment, advice, order,decision, recommendation, suggestion, 以及necessity, preference, plan, motion, idea等名词,其后的表语从句或同位语从句,也用“should+动词原形“表示虚拟语气.现代英语,特别是美国英语,常省去“should”,例：
The advice is that we (should) leave at once.
He idea that we (should)visit Great Wall was warmly
welcomed.
五、在“It is (was)+形容词（或过去分词）+that……”结构中,主语从句的谓语也用“should+原形动词“表虚拟语气
美国英语中省去should, 常用的形容词和过去分词有：
表示“要求”的：required, demanded, requested, desired, desirabl.
表示“建议”的：suggested, recommended,
表示“迫切、紧近、重要”的：imperative, urgent, necessary, essential, important, vital
表示“适当、较好”的：appropriate, advisable, better, preferable
表示“可能”的：probable, possible
表示“命令”的：ordered
例：It was necessary that we (should) make everything ready ahead of time.
It is required that nobody (should)smoke here.
六、由下列名词或短语引导,或含有某些词的从句中应用的虚拟语气
1．“Iest 以免、惟恐”引导的从句用“shuld+动词原形”.
He took a map with him lest he (should ) lose his wag there.
2．“whether不管、无论”引导的让步状语从句,有时用动词原形.
All things, whether you know or don' t know, exist in the world.
3．用“would rather/had rather' would just as soon"表示“宁愿、但愿”,后面的宾语从句谓语用过去式或动词原形表示对将来的要求,用过去时表示对现在的愿望,用过去完成时表示对过去做的事的懊悔.
Don' t live in the world, I would rather( I would just as
soon) you die.
I would rather you go tomorrow.
I would rather everything hadn' t happened in the past.
4．用“had hoped”表示原来希望做到而实际上未能实现的事情,其宾语从句的谓语用“would+动词原形”.
I had hoped that she would go to the U.S. and study there,
but she said she liked to stay in China.
5．在“It is（high/about）time+that”引导的定语从句中,定语从句的主谓语用一般过去时,偶尔也可以用would(或should)+动词原形,或had rather (would rather)+动词原形.
It is hihg (about)time that we left/should leave/ had better leave/had rather leave/ were leaving.(注意与“This is the first/second…time”后从句中用现在完成时的区别.
6．用“without/but for/in the absence of ”表示“要不是”,“如果没有”（相当于if it were not for…）表示条件时,句中一般用虚拟语气.（也可用陈述语气）
Without your help, I couldn' t finish my work on time.
In the absence of water and air, nothing could live
7．由“providing (that)/ provided (that)/on condition that/ in order that”引导的条件从句或目的从句,根据情况,可用虚拟语气.（有时也可用陈述语气）
They are willing surrender provided they are given free
passage.
8．在if引导的虚拟条件句中,若有were, had, should, 在书面语中可省去if ,将were等提到主语前,形成倒装.
Should there be a good film tomorrow. I would go to the
theatre with you.
Were it not for your help. I wouldn' t be succeed.
虚拟语气是高中学到的知识,确实有点难度,但肯用脑子,没有解不开的题!

对啊~~应该不用had wanted吧!
我记得MISS说过"退后一步"法,应该是wanted吧.

虚拟语气，对过去虚拟，从句用过去完成时
虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测， 建议等含义，虚拟语气所表示的含义不是客观存在的事实。
If I were you, I'd take them away.
如果我是你的话，我就会带走他们。
If I had met Li Hua, I could had told him.
如果我碰见了李华，我就告诉了他了。
If I had time. I could come to help you.
如果我有时间，我会来帮助你的。
He suggested that our class should be divided into five groups.
他建议说我们的班应该分成五个小组。
He speaks to us as if he had been there.
他给我们讲的好象他去过那儿。
虚拟语气的用法
1) 虚拟语气用在简单句中，表示祝愿，命令。
May you be happy.
祝你幸福。
May you have a good time.
祝愿你玩的痛快。
May the friendship between us last long.
祝愿我们的友情天长地久。
Have a good journey!
祝愿你旅途愉快！
You go out！
你出去！
2) 虚拟语气用在宾语从句中。动词 wish, suggest,order,insist, propose,等词后面的宾语从句表示的是一种虚拟语气， 宾语从句中的动词动作表示的只是一种愿望，要求。
I wish she would be on my side.
我希望她能站在我一边。
I wish I could help him.
我希望我能帮助他。
He insisted that all of us should be there on time by any means.
他坚持要我们大家想尽办法按时去那儿。
动词 demand, suggest, order, insist, propose 后面的从句中，"should" 可以省略。
The teacher suggested that we (should) clean the blackboard after class.
老师建议我们课后把黑板擦了。
He ordered that the students wash the clothes every week by themselves.
他要求学生每周都要自己洗衣服。
3) 虚拟语气用在主语从句中。
在句型 "It is important (necessary, strange, natural) that .... " 中，that 后面的从句中的谓语动词用： should + 动词原形
It's necessary that we should have a walk now.
我们有必要出去散散步。
It's natural that she should do so.
她这样做是很自然的。
It's important that we should take good care of the patient.
重要的是我们要照顾好病人。
4) 虚拟语气用在状语从句中。
虚拟语气最多地用在表示条件的状语从句和表示结果的主句中。在表示与事实相反的虚拟语气时，动词有三种时态形式，即现在，过去和将来。
与现在事实相反的：
条件从句 结果从句
If I (we,you,he,they)+ 动词过去式.. if I (he,she) were... I (we) should + 动词原形。 He (you,they) would + 动词原形。
与过去事实相反的：
条件从句 结果从句
If I(we,you,he,they)+ had + 过去分词 I(we)should + have+ 过去分词。He (you,they) would + have + 过去分词。
If I were you, I should buy it.
如果我是你，我就买了它。
If I had time, I would study French.
如果我有时间，我会学习法语的。
If she knew English,she would not ask me for help.
如果她懂英语的话，她不会找我帮忙的。
If you had got up earlier, you could have caught the train.
如果你早一点起床，就会赶上火车的。
If it were fine tomorrow,I would go shopping.
如果明天天气好，我就去买东西。
有关虚拟语气的几个问题：
1) 有时if引导的状语从句可以省略 if，而把从句中的动词 were, had 或 should 移到主语前面。
Were she younger, she would do it .
如果她年青点， 她就会干的。
Had he known her address, he would had gone to visite her.
如果他知道她的地址，他会去看她的。
2) 有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个主句或者一个条件从句。
I could help you.
我本来可以帮助你。
If I had time.
我要有时间该多好啊。
She should have come to the party.
她应该来参加聚会。
If he had much more money.
如果他有更多的钱就能...。
3) 虚拟语气中，条件从句的动词动作可以和主句的动词动作时态不一致。
If they had studied hard, they could do it easily now.
如果他们以前努力学习的话，现在干的就会容易些。
If he had not taken my advice, he wouldn't do it much better like this.
如果他不听取我的建议，他就不会干得这样好。
