If I were yu，I wuld seize the chance.（1）表示说话人所说的话不是事实，而是一种假设、猜测、怀疑 等，假设是不可能或者不大可能发生或实现的；（2）表示说话人的愿望、要求、命令、建议等
if条件句中的虚拟语气：
if条件句中的虚拟语气：We wuld be back in the htel nw if yu didn't lse the map.如果你没有把地图丢了的话，我们现在就回到旅馆了。They might have fund a better htel if they had driven a few mre kilmeters.　如果他们多开几公里的话，他们也许会找到一个更好的旅馆。Grace desn't want t mve t New Yrk because she thinks if she were t live there, she wuldn't be able t see her parents very ften.格蕾丝不想搬到纽约，因为她认为如果住在那里，她就不能经常看到她的父母了。
在if引导的虚拟条件状语从句中，谓语动词含有had、were、shuld时，可以把if省略，将had、were、shuld、culd提到句首，变成倒装句。Were it nt fr the supprt f the teachers, the student culd nt vercme her difficulty.如果没有老师们的帮助，这个学生克服不了她的困难。It might have saved me sme truble had I knwn the schedule.要是早知道时间表的话，可能会省去我一些麻烦。注意:若省略的条件句中的谓语动词是否定形式时，不能用动词的缩略形式。如:我们可以说:Were it nt fr the expense, I wuld g abrad nw. 但不能说:Weren't it fr the expense, I wuld g abrad nw.
在if引导的虚拟条件状语从句中，谓语动词含有had、were、shuld时，可以把if省略，将had、were、shuld、culd提到句首，变成倒装句。If I were in yur psitin，I wuld d the same. →Were I in yur psitin，I wuld d the same. 假如我处在你的位置，我也会这样干的。If yu had cme earlier，yu wuld have caught the bus. →Had yu cme earlier，yu wuld have caught the bus. 如果你来得早些，你就会赶上公共汽车了。If it shuld rain tmrrw，we wuld nt g climbing. →Shuld it rain tmrrw，we wuld nt g climbing. 如果明天下雨的话，我们就不去爬山了。
如果主句和从句是对不同时间的事实的虚拟，则被称为错综虚拟语气。此时主句常有明显的时间状语，并且动词的形式要根据它所表示的时间做出相应的调整。If yu had asked him yesterday, yu wuld knw what t d nw. （从句与过去事实相反，主句与现在事实相反） If I were yu, I wuldn’t have missed the cncert last night.If he had fllwed the dctr’s advice, he wuld be quite all right nw.
含蓄条件句的虚拟语气：
有时假设的条件不通过条件状语从句表达出来，而是隐含在某些词或短语中，或隐含在上下文中，这叫含蓄虚拟语气。常用的这类词或短语有withut(没有)、but fr(要不是)、therwise/r(否则)in case，fr fear that等。But fr his help, we wuld be wrking nw.Withut yur instructin, I wuld nt have made such great prgress.But fr yur help，we culdn’t have succeeded．(介词短语)I was ill that day．Otherwise，I wuld have taken part in the sprts meeting．(副词)He telephned t infrm me f yur birthday，r I wuld have knwn nthing abut it．(连词)
虚拟语气在宾语从句中的运用：
(1)wish后宾语从句中的虚拟语气
从句谓语动词:did(be动词一般用were)
从句谓语动词:had＋dne
从句谓语动词:wuld/culd/might＋d
(1)wish后宾语从句中的虚拟语气There is a gd scial life in the village, and I wish I had a secnd chance t becme mre invlved.　这个村子里的人们有良好的社交生活，我希望自己还能有机会去更多地参与其中。I wish I had tld him the way t the supermarket.我真希望我已经告诉了他到超市的路线。I wish yu culd give me the bk yu brrwed frm me last week tmrrw.我希望你明天能把你上周从我这儿借的那本书还给我。
(2)在表示“建议、要求、命令”等动词后的宾语从句中，谓语动词用“(shuld)＋d”，shuld可以省略。常见的这类动词有：①坚持：insist；②命令：rder、cmmand、mandate；③建议：advise、suggest、prpse、recmmend 、 prpse；④要求：request、require、demand、ask、desire;⑤外加一个敦促：urge、 一个提议mve；二主张：advcate； maintain ；三规定： rule；regulate； stipulateI suggest that we (shuld) hld a meeting next week.
特别提醒：①如果suggest不表示“建议”时，意为“暗示、表明”时，宾语从句用陈述语气。His pale face suggested that he was ill and I suggested he (shuld) have a rest.His silence suggested that he agreed with my decisin.②insist——坚持说、坚持认为——不用虚拟 ——坚决要求——用虚拟eg. He insisted that she was seriusly ill and that she (shuld) be sent t hspital at nce.eg. The by insisted that he was right.
(3)wuld rather、wuld sner,、wuld just as sn所接的宾语从句中，意为“宁愿；但愿”: 从句谓语动词用一般过去时，表示对现在或将来的虚拟； 从句谓语动词用过去完成时，表示对过去的虚拟。We wuld rather ur daughter stayed at hme with us, but it is her chice, and she is nt a child any lnger.　我们宁愿女儿待在家，陪在我们身边，但是选择权在她手上，毕竟她不再是个孩子了。I'd rather he had gne t the seaside with me the day befre yesterday.要是前天他和我一起去海边就好了。
虚拟语气在同位语从句和表语从句中的运用：
表示“建议、要求、命令、计划”等的名词，如advice、idea、rder、demand、plan、prpsal、suggestin、request等，其后的表语从句和同位语从句中谓语动词用“（shuld）＋d”，shuld可以省略。My suggestin was that necessary measures (shuld)be taken t prtect the children frm dangerus situatins.我的建议是采取必要措施来保护孩子们远离危险的境遇。His suggestin that we (shuld) g t Shanghai is wnderful.　他让我们去上海的建议很好。
虚拟语气在主语从句中的运用：
在“It is/was＋adj./dne＋that...”句型中，从句中的谓语动词用“(shuld＋)动词原形”。常见的形容词有imprtant、necessary、strange、natural、essential、urgent(紧急的）advisable （明智的）imperative（有绝对必要）常见过去分词有suggested、rdered、advised、requested、demandedIt is necessary that we (shuld) clean the rm every day.我们每天打扫房间是有必要的。It is required that middle schl students (shuld) take at least ne hur exercise every day.中学生被要求每天至少进行一个小时的锻炼。
虚拟语气在定语从句中的运用：
It's (abut/high/very) time＋that从句(从句用虚拟语气，谓语动词用一般过去时或shuld＋动词原形，shuld不能省略)，意为“是某人该做某事的时间了”。It's time that we went/shuld g hme.是我们该回家的时候了。It is high time that we tk/shuld take sme measures t slve the prblem.确实到了我们采取措施解决这个问题的时候了。
虚拟语气在状语从句中的运用：
lest／in case ／fr fear that引导的状语从句  lest（以防、以免）、in case（万一、以防）、fr fear that（因恐、免得）引起的状语从句中，谓语动词要使用（shuld）＋d的形式。  The ld wman walked slwly lest she（shuld）slip． He tk enugh mney fr fear that unexpected things shuld happen.He started ut earlier lest he shuld be late.
as if、as thugh、if nly从句中的虚拟语气：
as if、as thugh、if nly从句中的虚拟语气
as if/ as thugh: 好像、仿佛if nly：要是……就好了If nly the driver didn't drive s fast.要是司机没开那么快就好了。If nly she wuld pass the English examinatin!但愿她能通过英语考试！Mary's descriptin f the party was s vivid that I felt as if I had been there.玛丽对这次聚会的描述是如此生动，以至于我觉得我好像去过那里一样。
特别提醒：当as if/thugh引导的句子所叙述的是真实的或极有可能发生或存在的事实时，从句要用陈述语气。Lk at the dark cluds. It lks as if it is ging t rain. 看那乌云，好像要下雨了。
were it nt fr “要不是因为”含有责备和批评的虚拟语气：shuld/ ught t / culd / might +have +过去分词表示： 过去本应该而事实上没有 are late again. yu culd have cme earlier.你又来晚了， 你本能够早点到的。Yu have made a few mistakes. yu shuld have been a lit bit careful.你犯了几个错误， 比本应该更细心点。It is s near. we needn’t have taken a taxi.这么近， 我们本没有必要打车的。
在 It is a pity/a shame/ n wnder that…..句型中从句也常用(shuld )+动词原型 It’s a pity that yu (shuld) miss a gd chance.shuld可以翻译成什么？
If虚拟条件句的否定(含蓄条件句) 常考两个句型:If it weren't fr…和If it hadn't been fr…，其意为"若不是(有)" "要不是"。如:If it weren't fr water, n plant culd grw. 要是没有水植物就无法生长。If it hadn't been fr yur assistance ，we wuldn't have succeeded.=But fr yur assistance ，we wuldn't have succeeded.=Withut yur assistance ，we wuldn't have succeeded.如果没有你的帮助，我们不会成功的。

方法一　意义和语气判断法所谓意义判断法就是分析语境并确定应填情态动词的含义。因此熟练掌握每个情态动词的意义和用法是答题的前提。此外，情态动词主要表示说话人的语气、态度或情感，所以在解答此类试题时，要从说话者的角度去考虑问题，结合具体的语境来分析和判断，最后确定所需情态动词是否符合说话者的语气以及特定的情感需要。Gerge _____________________(nt g) t far. His cffee is still warm.
表示对过去发生的事情非常有把握的否定推测
can't/culdn't have gne　
方法二　时间判断法虚拟语气的考查重点在于判断句子是对现在、过去还是将来的动作进行虚拟。判断出时间后再根据相应的结构或句型确定谓语动词的形式。I wish I ____________(be) at my sister's wedding last Tuesday, but I was n a business trip in New Yrk then.
表示与过去事实相反的假设
