1、 虚拟语气使用方法归纳英语动词一般可带有三种不一样语气：陈说语气，祈使语气和虚拟语气。不一样语气用动词不一样形式（有还借助句法形式）来体现。一、 虚拟条件句条件句有两类：一类是真实条件句，一类是虚拟条件句假如假设状况是有也许发生，就是真实条件句，谓语用陈说语气。If you dont work hard，you will fail.If it is fine tomorrow，we will go for a picnic.假如假设状况过去、目前、未来都不存在，则为虚拟语气虚拟条件句和对应主句动词形式列表：条件从句谓语动词形式主句谓语动词形式与过去事实相反假设had donewould/cou
2、ld/might/should have done与目前事实相反假设过去时(waswere)would/could/might/should do与未来事实相反假设过去时 (waswere ) ；should do;were to dowould/could/might/should do1.与目前事实相反虚拟What would you do if you won the lottery?If I were you，I would seize the chance to go abroad. If I had a lot of money now，I would travel around
3、the world.2.与过去事实相反虚拟If you had been here yesterday，you would have seen her.If he had driven more carefully，he would not have had the car accident yesterday.3. 与未来事实相反虚拟If it were to rain/should rain/rained tomorrow，our plan would be put off.If we were to picnic，we would not be able to help.二、错综、混合虚
4、拟语气一般，在上面表格里反应是非真实条件句虚拟语气模式，从句和主句谓语动词时间是一致，假如两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气使用规定“各自为政”，即从句和主句根据各自假设时间不一样，采用上面表格中对应谓语动词形式。1. If I had seen you，I would not be so worried now. (从句是对过去假设，主句是对目前假设)2. If you had not watched television so late last night，you would not be so sleepy now.( 从句是对过去假设，主句是对目前假设)3. Ha
5、d you followed the doctors suggestion，you would be fine now.( 从句是对过去假设，主句是对目前假设) 4. If I had made some money last summer，I would go on holiday next month.( 从句是对过去假设，主句是对未来假设)5. You didnt let me drive. If we had driven in turns，you wouldnt be so tired now. (从句是对过去假设，主句是对目前假设)6. If I were your mother，
6、I would let you go out this weekend. (从句是对目前假设，主句是对未来假设)三、含蓄虚拟语气虚拟语气中“含蓄之美”指是含蓄虚拟语气。由于有时假设状况并不是以if引导条件从句形式出现，而是通过某些短语等形式暗示虚拟语气存在，常用词语有with，without，but for，otherwise，or，even，in case of，what if(假如将怎样)等等，这种句子往往有主句而无从句 (考试时多数状况是对过去假设)。But for your encouragement，I would not have been admitted to this uni
7、versity. （过去）Without water，all lives would die. （目前）He felt too tired yesterday，or he would have attended my party. （过去）I was having a meeting，otherwise I would have come to see you off. （过去）四、虚名词性从句虚拟语气具有should +V使用方法，这一某些重要是有关提议和命令有关从句，波及主语从句，宾语从句，表语从句，同位语从句以及以之有关形式主语宾语之类从句。记忆口诀：一种坚持(insist)，两个命令(
8、order，command)，三个提议(suggest，advise，recommend)，四个规定(ask，require，demand，request)。1. 宾语从句虚拟语气 He insisted that the meeting be put off.The general ordered (that) all the soldiers (should ) leave.He gives orders that the soldiers (should) leave. 2. 表语从句虚拟语气My suggestion is that we (should) stay here for
9、a rest.3. 同位语从句虚拟语气There is no suggestion that she (should) resign.4. 主语从句虚拟语气重要体目前It做形式主语三种状况： Its +p.p +that ； Its + adj. +that； Its + n. +that常用动词recommand，demand，desire，order，request，require，suggest,command常用形容词important，necessary，right，advisable，natural，strange，surprising，regretful,urgent，vital
10、，insistent，essential常用名词duty，pity，no surpise，no wonder，shame，regret其实这些词在句子中其实也有提议命令类似意思Its important that you should take the medicine.Its a pity that you should refuse the invitation.Its essential that we should learn some knowledge about fist aid.Its demanded that all the students should go to th
11、e playground. It was suggested that he should join the club activities.5. It为形式宾语状况实际上是上面形式主语一种变形，是以it为形式宾语复合宾语从句，it背面宾语补足语多为形容词或名词，常用词就是上面形式主语背面那些词。I consider it vital that he (should) think deeply before acting.We think it necessary that the meeting (should) be put off.6. 某些词语如suggest，insist 等有双重含
12、义，因此在使用时候要注意什么时候用虚拟语气，什么时候不用虚拟语气。Her smile suggested that she was in favor of the plan.We insisted that what the boy did was wrong. 五虚拟语气在特殊句式中运用，重要有两种状况：I. would rather，Its time，for fear thatwould rather在使用时要注意它不一样使用方法。由于自身would rather可以直接接动词原形，构成would rather do sth. (than do sth.else)；或者would do s
13、th. rather than do sth.else.而虚拟语气would rather 是这样使用would rather sb. did(对目前或未来假设)/ had done(对过去假设)I would rather he didnt go now.They would rather they hadnt attended the party. Its (about) (high) time (that)从句中常用过去式(有时也用should do)，含提议意思。汉语意思为“是该做时候了”，也等于Its time for sb. to do sth. Its high time (th
14、at) we went home.Its high time that we (should) go home.Its high time for us to go home.for fear that 背面可以接虚拟语气should do，也可以接其她语气，但仍然会有一种情态动词。I will not make a noise for fear that I should / might disturd you.II. wish+clause；as if/ though+ clause；If only这三种状况虚拟语气有点相似。wish后宾语从句，谓语动词要用虚拟语气，其形式重要有三种wis
15、h sb. did(对目前虚拟)；wish sb. had done(对过去虚拟)；wish sb. would do (对未来虚拟).偶尔在对过去虚拟时，也会出现wish sb. would have done状况。I wish I knew what was going to happen.She wished she had stayed at home.I wish I would have seen her last night.此时要注意体现语气很强时用How sb. Wish+ clause，其使用方法同上。假如要用was仍然换成were.How I wish I were a bird.as if/ though出现虚拟语气重要有两种状况：主句+as if/ though引导状语从句； seem/ look/ smell +as if/ though引导表语从句。主句+as if/ though引导状语从句：主句+as if/ though+主语+did/ were(对目前假设)；主句+as if/ though+主语+could/ would do(对未来假设)；主句+as if/ though+主语+had done(对过去假设)seem/ look/ smell等从句状况
