2、,shall we?我们休息一会儿，好吗?3.疑问语气(the interrogative mood)：用来提出问题e.g.Where are from?4.虚拟语气(The Subjunctive Mood)虚拟语气用于表示主观愿望和假设的虚拟情况。虚拟语气不太顾及事实的存在，它表现出说话人的主观因素比拟多。所以说话人所讲的内容往往是与事实相反的；或是其实现的可能性微乎其微，甚至于没有实现的可能性。当然，有时为了使说话的语气客气、缓和、委婉，也使用虚拟语气。e.g.I wish you were more careful.但愿你更细心一些。If Ihad more money,I would
3、 buy abigger apartment.我要是有再多一点钱，我就买一套更大一些房子。Would you mind shutting the door?劳驾您把门关上。二、虚拟语气的种类：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。虚拟语气在条件句中应用比拟多；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。三、真实性条件句真实条件句用于陈述语气，假设的情况有可能发生,各种构造如下：条件从句主句一般如今时shall/will+动词原形祈使句情态动词一般如今时e.g.If he
4、 es,he will bring his violin.假如他来，会带小提琴来的。典型例题：The volleyball match will be put off if it_.A.will rain B.rains C.rained D.is rained答案B。真实条件句主句为将来时，从句用一般如今时。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.(错)If you leave now,you are never going to regret it.(对)If you leave now,you will never regret it
5、.2.表示真理时，主句谓语动词不用shall(will)+动词原形，而直接用一般如今时的动词形式四、非真实条件句1.虚拟语气可以表示过去，如今和将来的情况，时态的根本特点是时态往后推移2.与如今事实相反的假设一般过去时(be用were)Would/should/could/might/ought to+动词原形1.If they werehere,they would help you.2.if we had enough money,we would buy aputer.3.if Iwere you,I wouldnt do it.4.if it rained tomorrow,wed s

7、should have done so too.5.I should never have done it if Ihadnt been so hard up.与将来不大可能发生的事情的假想一般过去时/should/would+动词原形Should/would/could/might/ought to+动词原形1.If you suc ceeded,everything would be all right.3.if he went,would you go too?与将来事实相反的.假设were+不定式Should/would/could/might/ought to+动词原形1.if sh
8、e were to lose her place they would be ruined.2.if you were to speak to him,it would carry more weight.五、混合条件句(也叫：错综时间条件句)有时，主句与从句的动作发生在不同的时间，主句从句谓语动词的虚拟语气形式因时间不同而不同，这种条件句叫做混合条件句e.g.1.If you had asked him yesterday,you would know what to do now.假如你昨天问过他，今天就知道做什么了。(从句与过去事实相反，主句与如今事实相反。)2.If it had ra
9、ined last night(过去),it would be very cold today(如今).假如昨晚下过雨，今天就会很冷了。3.if youd listened to me,you wouldnt be in such trouble now.假如你听了我的话，你如今也不会这样费事了4.if it hadnt been for her care,I should not be speaking to you now.假如不是她照顾我，我也不会在这里和你讲话5.If the doctor had e in time,any would still be alive.假如医生及时赶到，
10、AMY如今还活着。六、含蓄条件句：含蓄条件句是指非真实条件句中的条件从句有时不表出来,只暗含在上下文中。含蓄条件句常见的表达方式有：1.定语从句和状语从句e.g.anyone who had married such agirl as she would have been regretful.谁娶了像她这样的姑娘都会懊悔的help was promised where it should bee necessary.要是需要的话就容许给予帮助2.介词及介词短语but that,as though,once,but for,without,with,under,undercondition,s

13、住这个时机，你会懊悔的he felt very tired yesterday,or he would have helped you.他昨天觉得很累，不然会帮你的4.通过分词短语表示条件e.g.Given more time,we could have done it better.Legalizing this drug would have disastrous consequence.使_合法化会有灾难性的后果5.用动词不定式表示条件e.g.It would be amistake not to help him.特殊情况：情态动词在日常用语中用得很多，使句子显得比拟委婉；这类谓语算不
14、算虚拟语气很难说，但有两点是肯定的：一是它们不受时态的影响，虽然形式接近过去式，却常指如今的情况，而且和虚拟语气在形式上一致，在不少情况下几乎可以说是一种含蓄的虚拟条件句；二是它们不表示事实，常带有主观色彩，因此使句子显得很委婉。e.g.I should think that might be agood solution.could Itrouble you with aquestion?would you mind taking part?would you like some tea?七、虚拟语气在宾语从句中的运用1.虚拟语气用在would rather，would(just)as so
15、on，would sooner，would prefer(希望)等后接的宾语从句中。意指某人宁愿让另一个人做某事，其后的宾语从句的谓语动词需用虚拟语气。假设表示如今或将来要做某事，从句谓语动词需用一般过去时，表示过去已经做的事，从句谓语动词用过去完成时。e.g.The manager would rather his daughter did not work in the same office.经理宁愿她女儿不与他在同一间办公室工作。To be frank，Id rather you were not involved in the case.坦率地说，我希望你不要卷入这件事。You dont have to be in such ahurry.I would rather you went on business first.你没有必要这么着急，我宁愿你先去上班。Id rather you didnt make any ment on the issue for the time being.我倒希望你暂时先不要就此事发表意见。Frankly speaking，Id rather you didnt do anything about it for the time being.坦白地说我宁愿你如今对此事什么也不做。Wouldnt you rather your chil
