Ⅱ.含蓄虚拟条件句 英语中某些假设的条件句不是通过 if 从句表达出来，而是使用介 词短语、副词或非谓语动词等形式来代替 if 条件句，句子的谓语也常 用虚拟语气来表达，这种形式的句子就叫含蓄虚拟条件句。常用的含
蓄词或短语有：with, without, otherwise, or, but, or else, but for，分词(短 语)等。
____w__o_u_ld___h_a_v_e__jo_i_n_e_d____ our party. 真遗憾，要不是他昨天工作到很晚，他不会不参加我们的联欢会
的。
说明：第一句中的第二个“条件”指的是条件词 if；第二句的“含 蓄用词”指 without, or, otherwise 等；第四句中“据时填”指的是按句 子虚拟的时间(过去、现在、将来)来使用相对应的时态(参考 if 条件句 的虚拟用法)。

人教版高中英语选修六Unit2Poem知识讲解虚拟语气(2)
虚拟语气（2）编稿：牛新阁审稿：王春霞概念引入上一单元我们学习了虚拟语气中与现在、将来事实相反的虚拟条件句及宾语从句的虚拟语气。
本单元要继续学习虚拟语气中与过去事实相反的虚拟条件句，及虚拟语气在其它从句中的应用。
首先，我们先看下面含虚拟语气的句子：1. We would have won, if Jack had scored that goal.2. We would have won if we hadn’t stayed up so late the night before.3. We would have won the championship, if we had got Mr Han to coach us.4. If she had studied harder, she would have got the diploma.这些句子都是与过去事实相反的虚拟条件句。
下面我们就来学习这部分内容。
用法讲解与过去事实相反的虚拟条件句虚拟条件句的动词形式假设类型条件从句（if从句）谓语动词主句的谓语动词与现在事实相反一般过去式(be用were) would/should/might/could +动词原形与将来事实可能相反1）一般过去式(be只用were)2）were to + 动词原形;3）should + 动词原形would/should/might/could+动词原形与过去事实相反had done would/should/might/could + have过去分词从表格可知，虚拟条件句与过去事实相反时，条件从句的谓语用过去完成时，而主句的谓语用would/should/might/could加现在完成时形式。
If he had taken my advice, he would not have made such a mistake.如果他听我的劝告的话，就不会犯这样的错误了。
人教版选修六第二单元虚拟语气(2)
虚拟语气（2）1、wish后的宾语从句中的虚拟语气wish和hopewish表示“愿望”,而hope表示“希望”。
wish后描述的是人们优美的愿望，很有可能是不能实现的，所以wish就要用虚拟语气，而其虚拟语气是通过宾语从句的谓语动词的变化实现的。
现在时过去时wishdid（be动词用were）希望“同步”发生某事had + donecould希望“之前”发生某事将来时would希望“之后”发生某事(1)I wish Iwereten years younger.我希望我能够年青十岁。
I wish Iknewhow to drive a car.真希望我会开车。
(2)I wish Ihad goneto the football match last night.我希望昨晚我去看足球比赛了。
（注意：last night表明用had gone）(3)He wishes youwould goand visit him.他希望你会来看他。
I wish the boyscould bequiet.我希望男孩们能保持安静。
注意：从句谓语动词的变化不受wish的时态的影响，无论wish还是wished，我们只需判断从句谓语动作是和wish同步发生，还是在wish前，还是在wish后发生的，就可以了。
不要受前面这个词的变形影响。
试一试：1) I wish I ________a bird. (be)2) I wish/wished I ________ (not eat) so much watermelon.3) The party was terrible, I wish I ________ (never go) to it.4) I wish it ________ (rain) tomorrow.答案与解析：1) were。
现在的愿望，即与wish同步的愿望，用were。
不用was。
2)hadn’t eaten。

一、虚拟语气用于非真实条件句 第一单元详细讲述了虚拟语气用于与现在事实相反和与将 来事实可能相反的非真实条件句，所以本单元学习与过去 事实相反的非真实条件句，主句和从句的形式如下：
从句 if ＋主语＋had＋过去分词 主语＋would/should/could/might＋have＋过去
主句 分词
If he had won the game, he wouldn’t have been so sad. 如果他赢得比赛的话，他就不会那么悲伤了。 If you had taken my advice, you would not have failed in the exams. 如果你当时听取我的忠告，你考试不会不及格的。
He gave the advice that we (should) do the work carefully. 他建议我们认真做这项工作。
3．as if/as though从句以及if only 后的句子常用虚拟语气。
as if/as though/if
only
时间
谓语动词的虚拟形式
与过去相反 had＋过去分词
[考题印证3]
3－I ________through that bitter period
without your generous help. A．couldn’t have gone C．wouldn’t go
B．didn’t go D．hadn’t gone
解析：选 A 。考查虚拟语气。英语中， without, with, or, otherwise 等可构成含蓄虚拟语气，相当于条件状语 从句“If it hadn’t been your generous help”，表示与过去 事实相反，此时句中的谓语动词应用should/could/would ＋have＋过去分词。据此可知A项当选。句意：假如当 时没有您慷慨相助，我就不会度过那段艰难的时期。
高二英语选修6学案Unit2PoemsSectionⅡ含解析
Unit 2PoemsSection ⅡGrammar语法指南虚拟语气（2)本单元语法重点是讲解虚拟语气中与过去事实相反的情况.1．基本句型：If＋主语＋had＋过去分词,主句主语＋should/would/could/might＋have＋过去分词If you had come yesterday，you would have met him．要是你昨天来的话，你就会遇到他了。
If you hadn't helped us，we couldn’t have made such great progress．要是当时你没有帮助我们，我们不会取得如此大的进步.2．if省略句在条件句中可以省略if，把were，had，should提到句首，变为倒装句式。
如：Were I you，I would accept the challenge．如果我是你的话,我会接受挑战的。
Had you informed me earlier，I wouldn't have signed the contract．要是当初你早点告诉我，我就不会签那个合同了。
Should I have time，I would help Tom with his maths．要是我有时间，我就帮汤姆学数学。
3．错综时间条件句如果条件句的动作和主句的动作不是同时发生，这时主句和从句的谓语动词的形式应根据它要表达的具体时间来调整。
如：If you had repaired the house yesterday，it wouldn't be wet now．要是你昨天修了房子的话,房子现在就不会湿了。
（过去→现在) If I were you，I wouldn’t have missed the movi e last night．如果我是你,我就不会错过昨晚那部电影。
（现在→过去）4．(1）If it be not for.。

He behaves as if he owned the house.
(But he doesn’t own it or probably doesn’t own it or we don’t know whether he owns it or not.)
She talks about Rome as though she had been there herself.
The Subjunctive Mood
虚拟语气用来表示说话人 所说的话不是一个事实， 而只是一种愿望、假设、 怀疑、猜测、空想等。
Everyone has wishes!
When I was young I wished I could have been a model. But I was not tall enough, so I couldn’t become a model. If I had grown taller, I would have been a model.
主句与从句的动作发生在不同的时间, 这时主从句位于动词的虚拟语气形式因 时间不同而不同, 这叫做混合条件句。
例句中从句与过去事实相反, 主句与 现在事实相反
If you had asked him yesterday, you would know what to do now.
If the staff had been more careful,
他那样对待我, 好像我是陌生人似的。
He treats me as if I were a stranger.

高中英语学习材料***鼎尚图文理制作***虚拟语气（2）编稿：牛新阁审稿：王春霞概念引入上一单元我们学习了虚拟语气中与现在、将来事实相反的虚拟条件句及宾语从句的虚拟语气。
本单元要继续学习虚拟语气中与过去事实相反的虚拟条件句，及虚拟语气在其它从句中的应用。
首先，我们先看下面含虚拟语气的句子：1. We would have won, if Jack had scored that goal.2. We would have won if we hadn’t stayed up so late the night before.3. We would have won the championship, if we had got Mr Han to coach us.4. If she had studied harder, she would have got the diploma.这些句子都是与过去事实相反的虚拟条件句。
下面我们就来学习这部分内容。
用法讲解与过去事实相反的虚拟条件句虚拟条件句的动词形式假设类型条件从句（if从句）谓语动词主句的谓语动词与现在事实相反一般过去式(be用were) would/should/might/could +动词原形与将来事实可能相反1）一般过去式(be只用were)2）were to + 动词原形;3）should + 动词原形would/should/might/could+动词原形与过去事实相反had done would/should/might/could + have过去分词从表格可知，虚拟条件句与过去事实相反时，条件从句的谓语用过去完成时，而主句的谓语用would/should/might/could加现在完成时形式。
If he had taken my advice, he would not have made such a mistake.如果他听我的劝告的话，就不会犯这样的错误了。
（事实：没有听我的话---he didn’t take my advice）If you had come a few minutes earlier，you would have met him.要是你早来几分钟的话，你就见到他了。
（事实：来晚了---you came late）If She hadn’t been so strict with herself, she wouldn’t have made such great progress.她要是对自己要求不严格，她就不会有这样大的进步。
（事实：她对自己很严格---she was strict with herself）虚拟语气中的倒装条件从句中的were，had, should可放句首，省略if，条件句成为倒装句。
Had you (If you had) invited us, we would have come to your party.如果你邀请我们了，我们会参加你的聚会的。
Were I ( If I were ) you, I would do more practice.如果我是你，我会做更多的练习。
Should she ( If she should) lend us a helping hand, we would succeed.如果她帮助我们，我们会成功的。
注意：条件句或省略的条件句可以放句尾。
如：We would have lost our lives had it not been for the policeman.如果没有这位警察，我们就没命了。
【高清课堂：虚拟语气（上）法则二：千变万化的表现形式。
】千变万化的表现形式if虚拟条件句的三个公式的倒装我们说完了，那是不是就这一种变化呢？我们接下来看看它的千变万化的表达形式。
含蓄虚拟语气有时假设的条件不通过条件从句表达出来，而是隐含在某些介词短语（如without，but for等）或上下文中。
1. I was very tired. Otherwise, I would have gone to the party with you last night.我太累了。
否则，我昨晚就同你去聚会了。
（otherwise代替了条件句“If I hadn’t been very tired”）2. Life without any friends or family would be lonely for me.如果生活既没有朋友也没有家庭，那对我来讲就太孤独了。
（without短语代替“If there were no friends or family”）3. If only we had done as we were told. 如果我们按照被告知的去做，该多好呀。
4. If only I had known the answer before the test. 考试前就知道答案，那该多好呀。
（if only表示“要是......该多好呀”，表示假设的内容成立时的感受，但是并没有明确说出这种感受）5. But for the rain, we should have had a pleasant journey.要不是下雨，我们本来会有一个愉快的旅行的。
（But for the rain，代替的是“If it hadn’t rained”）混合虚拟语气什么混合了呢？从下面例句中我们看出是时态方面的混合，即主句与从句所指的时间不一致，这时主从句的时态根据实际的时间概念确定。
1. If I had eaten breakfast several hours ago, I would not be hungry now.如果我几小时前吃了早餐的话，我现在就不会饿了。
（从句与过去事实相反，主句与现在事实相反）2. If I were you, I would have gone to the theatre. 如果我是你，我就去剧院了。
（从句与经常的状况相反，属特殊用法，主句与过去事实相反）3. If you hadn’t helped me, I would be still working now.如果当时你没有帮我的话，现在我还在工作呢。
（从句与过去事实相反，主句与现在事实相反）分裂虚拟语气在这种句型中，虚拟语气通常省略条件句，只保留主句，后面再加上真实的情况。
1. He would gain weight but he doesn’t eat much.他会增加重量的，但是他吃得不多。
（=If he ate much, he would gain weight, but he doesn’t eat much.）2. I would go to visit them but I don’t think they are anxious to see me.我本来是会看他们的，但是我想他们不会急于见我。
（=If they were anxious to see me, I would go to visit them.）3. I would have invited her to the party but I did n’t know her well.我本来想邀请她来聚会的，但是与她不怎么熟。
注意：这种句型的关键词but。
■虚拟语气在其它从句中的用法（1）主语从句的虚拟语气这种主语从句由连词that引导，虚拟语气为“（should）动词原形”。
其中should可省略。
should 常译成“应该、必须、竟然”。
注意下面句型：1．It is／was + 形容词+ that从句当形容词为important, necessary，strange，natural，appropriate, proper, right, desirable, essential, surprising, unthinkable等或名词短语a good idea时。
如：It is important and necessary that we (should) master a foreign language．我们精通一门外语是重要而且必要的。
It is proper that an independent inquiry (should) take place. 进行独立调查很合适。
It is strange that he (should) refuse your help．他竟然拒绝你的帮助真是奇怪。
It is surprising that you (should) not understand me! 你竟然不理解我，真令人吃惊！2. It is／was + a pity/a shame / a surprise / no wonder + that从句It’s a pity that you (should) miss a good chance.你竟然错过一个好机会真是遗憾。
3. It is demanded/suggested/ordered/required/ ….that-clauseIt is suggested that he (should) not spend too much time watching TV.有人建议他不应该花太多时间看电视。
It is proposed that the plan (should) be delayed. 有人建议推迟这项计划。
表语从句的虚拟语气1. 在名词“suggestion, proposal, idea, plan，order, advice, desire, requirement, request, command, decision, recommendation等”后面的同位语从句或表语从句中，用“should+动词原形”，其中should可省略。
My idea is that we (should) get more people to attend the conference．我的建议是我们应该让更多的人参加会议。
2. as if ( as though)引导的表语从句中的虚拟语气。
It seems as if the meeting would never end. 看来会议没完没了。
（与将来相反）It seems as though he had been there many times. 好像他已经去过那里好多次了。
（与过去事实相反）It seems as if nobody knew what happened. 好像没有知道发生了什么事。
