虚拟语气Learning Goals：1.Knowing what the subjunctive mood refers to.2.Knowing the difference forms of the subjunctive forms.3.Master the structure of the subjunctive mood about“if”.4.Practices.虚拟语气概念：1.表示说话人所说的话不是一个事实，而是一个假设、怀疑、猜测等（常见于条件状语从句或让步状语从句）。2.表示说话人的愿望、建议、要求、命令等（常见于名次性从句）。简单来说：不是事实或不大可能发生的事情，用虚拟语气来表述。If引导的虚拟条件句注意：要区分if引导的真实条件句和if引导的虚拟条件句表示虚拟的，几乎无法实现的时候，采用虚拟语气。If引导的虚拟条件句TYPES:特殊：错综时间/倒装句省略IF等与与过去事去事实相反相反与与现在事在事实相反相反与将来事与将来事实可能相可能相反反一.与过去事实相反If he had got up earlier,he could have caught the train.If引导的虚拟条件句 主句与过去事实相反的假设If+主语+had+动词的过去分词（即：If+动词过去完成时）主语+would(should/might/could)+have done二.与现在事实相反 If I were you,I would buy a red skirt.If I had a million dollars,I would donate 30%of it to the charity.If引导的虚拟条件句主句与现在事实相反的假设If+主语+动词过去式（be动词一般用were）即：If+一般过去时If+主语+would(could/should/might)+动词原形三.与将来事实可能相反If it rained tomorrow,I wouldnt attend the party.If it were to rain tomorrow,I wouldnt attend the party.If you should come tomorrow,you would find the new manager working in the office.If虚拟条件句主句与将来事实可能相反的假设1.If+主语主语+动词过去式动词过去式2.If+主语主语+were to+动词原动词原形形 3.If+主语主语+should+动词动词原形原形主语+would(could/should/might)+动词原形特例1.错综时间条件句定义：主句和从句动作发生的时间不同例1）If they had studied hard,they could finish the work in a very short time.如果他们当时刻苦学习，现在就能快速完成这份工作了（从句说明过去，主句说明现在）。2）If I were you,I would have gone to her birthday party yesterday.如果我是你，我就去参加她昨天的生日聚会了（从句说明现在，主句说明过去）。要根据动作发生的时间选择恰当的动词形式。与过去相反，以前没有刻苦学习与过去相反，以前没有刻苦学习与现在事实相反，现在没有快速完成与现在事实相反，现在没有快速完成特例2.省略If的条件从句如果条件句中有were/had（助动词）/should时，可使用倒装句结构省略If，把were/had（助动词）/should放句首。如果条件句是否定句时，not应置于主语后，不能与were/had（助动词）/should等缩略成werent/hadnt/shouldnt.例：Had I seen him then,I would have been very happy.=If I had seen him then,I would have been very happy.Should I have time,I would go with you.=If I should have time,I would go with you.Were I not so busy,I would go to the concert.=If I werent so busy,I would go to the concert.Practice1.If you had told me in advance,I _ him at the airport.A.would meetB.would have metC.would had metD.should meetPractice1.If you had told me in advance,I _ him at the airport.A.would meetB.would have metC.would had metD.should meet2.If it _ tomorrow,I would not attend the party.A.rainedB.rainsC.had rainedD.were to rain3.I would have gone to the meeting if I _time.A.had had B.have hadC.had D.would have hadIf it _ tomorrow,I would not attend the party.A.rainedB.rainsC.had rainedD.were to rain3.I would have gone to the meeting if I _time.A.had had B.have hadC.had D.would have hadIf it _ tomorrow,I would not attend the party.A.rainedB.rainsC.had rainedD.were to rain3.I would have gone to the meeting if I _time.A.had had B.have hadC.had D.would have had4.If me father _ here now,he _ tell me what to do.A.were;wouldB.was;illC.had been;wouldD.is;ill5.If he _ my advice,he wouldnt have lost his job.A.followedB.should followC.had followed D.would follow4.If me father _ here now,he _ tell me what to do.A.were;wouldB.was;illC.had been;wouldD.is;ill5.If he _ my advice,he wouldnt have lost his job.A.followedB.should followC.had followed D.would follow4.If me father _ here now,he _ tell me what to do.A.were;wouldB.was;illC.had been;wouldD.is;ill5.If he _ my advice,he wouldnt have lost his job.A.followedB.should followC.had followed D.would follow6.If I _ in the 22nd century,I _ my vocation in a very different way.A.should live;would spendB.will live;should spendC.are living;should have spentD.will be living;would have spent7._ it rain tomorrow,we would have to put off the visit to Mountain Tai.A.Were B.Should C.Would D.Will 6.If I _ in the 22nd century,I _ my vocation in a very different way.A.should live;would spendB.will live;should spendC.are living;should have spentD.will be living;would have spent7._ it rain tomorrow,we would have to put off the visit to Mountain Tai.A.Were B.Should C.Would D.Will 6.If I _ in the 22nd century,I _ my vocation in a very different way.A.should live;would spendB.will live;should spendC.are living;should have spentD.will be living;would have spent7._ it rain tomorrow,we would have to put off the visit to Mountain Tai.A.Were B.Should C.Would D.Will THANK YOU!
