If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设) 3. If I were you, I would seize the chance to ‎ go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctors suggestion, you would be fine now.( 从句是对过去的假设，主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设) 6. You didnt let me drive. If we had driven in turns, you wouldnt be so tired now. (从句是对过去的假设，主句是对现在的假设) 7. If Lily didnt attend todays party, she could not have the chance to work in the company next week. (从句是对现在的假设，主句是对将来的假设) 虚拟语气在if引导的条件状语从句中，特别注意虚拟语气与倒装的结合，前提是省略if，这种情况多见于过去和将来的假设，具体表现是将if省略，把had, were, should之类词语提前构成倒装。例如： Were I you, I would go. Should it happen, what should you do? Had he recognised me, he would have come over. ‎ 虚拟语气中的含蓄之美指的是含蓄虚拟语气。因为有时假设的情况并不是以if引导的条件从句形式出现，而是通过一些短语等形式暗示虚拟语气的存在，常用的词语有without, but for, otherwise, or等等，此时我们可以从意思上推断出虚拟语气的时间(考试时多数情况是对过去的假设)。 But for your encouragement, I would not have been admitted to this university. (过去) Without water, all lives would die. (现在) 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) 2.should+do的用法 虚拟语气的第二模块就是含有should +do的用法，这一部分主要是有关建议和命令的相关从句，包括主语从句，宾语从句，表语从句，同位语从句以及以之相关的形式主语宾语之类的从句。 这一部分的词主要有常见的动词有advise, suggest, insist, order, require, recommend, command以及相关名词等等。记忆口诀：一个坚持(insist)，两个命令(order, command)，三个建议(suggest, advise, recommend)，四个要求(ask, require, demand, request)。 1. 宾语从句的虚拟语气 ‎ ‎ He insisted that the meeting be put off. He gives orders that the soldiers (should) leave. 2. 表语从句的虚拟语气 My suggestion is that we (should) stay here for a rest. 3. 同位语从句的虚拟语气 There is no suggestion that she (should) resign. 4. 主语从句的虚拟语气主要体现在It做形式主语的三种情况： Its +p.p +that ; Its + adj. +that; Its + n. +that 常用的动词:recommand, demand, desire, order, request, require, suggest,command 常用的形容词:important, necessary, right, advisable, natural, strange, surprising, regretful,urgent, vital, insistent, essential 常用的名词:duty, pity, no surpise, no wonder, shame, regret 其实这些词在句子中其实也有建议命令类似的的意思 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 the playground. It was suggested that he should join the club activities. 5. It为形式宾语的情况实际上是上面形式主语的一种变形，是以it为形式宾语的复合宾语从句，it后面的宾语补足语多为形容词或名词，常见词就是上面形式主语后面的那些词。 I consider it vital that he (should) think deeply before acting. 6. 某些词语如suggest, insist 等有双重含义，所以在使用的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. 3.特殊句式 ‎ 虚拟语气的第三大模块指的是虚拟语气在特殊句式中的运用。句这些句式使用的虚拟语气与上面的虚拟语气会有所不同： would rather在使用时要注意它的不同用法。因为本身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 sth. rather than do sth.else.而虚拟语气的would rather 是这样使用的would rather sb. did(对现在或将来的假设)/ had done(对过去的假设) 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), 含建议的意思。汉语的意思为是该做;的时候了，也等于Its time for sb. to do sth. Its high time (that) we went home. Its high time that we (should) go home. for fear that 后面可以接虚拟语气should do，也可以接其他语气，但依然会有一个情态动词。 I will not make a noise for fear that I should / might disturd you. wish+clause; as if/ though+ clause; If only这三种情况的虚拟语气有点相似。 ‎ wish后的宾语从句，谓语动词要用虚拟语气，其形式主要有三种wish sb. did(对现在的虚拟); wish sb. had done(对过去的虚拟); wish sb. would do (对将来的虚拟).偶尔在对过去的虚拟时，也会出现wish sb. would have done的情况。 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. ★此时要注意表示语气很强时用How sb. wish+ clause, 其用法同上。如果要用was依然换成were. 例如：How I wish I were a bird. as if/ though出现的虚拟语气主要有两种情况：主句+as if/ though引导的状语从句; seem/ look/ smell +as if/ though引导的表语从句。 主句+as if/ though引导的状语从句：主句+as if/ though+主语+did/ were(对现在的假设);主句+as if/ though+主语+could/ would do(对将来的假设);主句+as if/ though+主语+had done(对过去的假设) seem/ look/ smell等的从句情况基本上和上面一致。例如： She talks as if she knew everything. 注意不需要用虚拟语气的情况 If ‎ only引起的感叹句要求用虚拟语气，表示愿望。形式为：用过去式或者would/ could do, 表示与现在或未来事实相反的愿望;用过去完成式表示与过去事实相反的愿望。 If only he were here! If only you would listen to our advise! If only I had not been busy last week! ★If only 也可以用于虚拟条件从句中，如： If only I had more money, I could buy a car!‎
