虚拟语气和倒装
语法：虚拟语气和倒装句
虚拟语气虚拟语气在英语里主要用来表达：1.非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人的主观愿望。
2.强制性虚拟语气，表示建议、命令、劝告等意思，表示强烈地要求做到、必须做到这样的含义。
虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而起一般有明显的标志。
难点释疑一、If型If条件状语从句表示的虚拟语气，其句型结构如下：特别值得注意的是，这种虚拟语气的形式存在交叉虚拟，即如果从句发生的动作和主句发生的动作不一致(例如：从句动作发生在过去，主句动作发生在现在)，谓语动词要根据表示的时间进行调整。
例如：If Peter had applied for the post, he would probably get it now.要是彼得申请了那职位，他很可能现在就得到了。
If he had left for Shanghai yesterday, he would get there now.如果他昨天动身去上海的话，他现在已经到那里了。
二、Wish型1.wish后的宾语从句用虚拟语气，其句型结构如下：与过去事实相反wish that 从句的谓语动词用had done与现在事实相反wish that 从句的谓语动词用did与将来事实相反wish that 从句的谓语动词用would/could do例如：I wish they would change the menu.他们要是改变一下菜单就好了。
I wish I hadn’t spent so much money.我要是没花那么多的钱就好了。
同样地，在as if/as though引导的宾语从句中和以if only引导的带有感叹色彩的虚拟语气句子中，谓语动词与wish引导的宾语从句中的虚拟形式相同。
2.由if only 引导的虚拟语气与过去事实相反if only 谓语动词用had done与现在事实相反if only 谓语动词用did例如：If only she had asked someone’s advice! 她要是征求了别人的意见就好了！3.由as if/as though 引导的虚拟语气与过去事实相反as if/as though谓语动词用had done与现在事实相反as if/as though谓语动词用did例如：He talks about Rome as if he had been there himself.谈论起罗马来就像他去过似的。

英语语法中的倒装句和虚拟语气
英语语法中的倒装句和虚拟语气英语是一门语法非常严密的语言，其中倒装句和虚拟语气是比较有代表性的两种语法现象。
它们的运用非常灵活，不但能够丰富语言表达的层次，还能够措辞优美、言简意赅。
下面我们就来探讨一下这两种语法现象的用法与特点。
倒装句所谓倒装句，指的是在语句中将主语和谓语的位置颠倒的现象。
具体来说，有三种情况：1.整个谓语做倒装。
例如：Never had I seen such a beautiful view before.（我以前从没看过这么美的风景。
）Only by working hard can we achieve our goals.（只有通过努力工作，我们才能实现我们的目标。
）注意，这种倒装通常用于强调句子中的某一部分，比如"never"和"only"这样的副词。
在平常的口语和写作中，这种用法并不常见。
2.助动词和主语的位置互换。
例如：Are you going to the party tonight? -> Are you not going to theparty tonight?He has finished the report. -> Has he finished the report?这种倒装在否定句和疑问句中比较常见。
3.只有谓语的一部分做倒装。
例如：Up the hill walked the little girl.（小女孩沿着山坡走了。
）In the garden sat the old man.（老人坐在花园里。
）这种倒装通常在口语和文学作品中出现，英语中很多歌曲和诗歌也会使用这种语法结构。
总体来说，倒装结构让英语句子的语序独特，增加了句子的语言美感和表达效果。
虚拟语气虚拟语气（Subjunctive Mood）是英语语法中非常重要的一个概念。
虚拟语气主要用来表达一些虚构的假设或者反事实情况，比如愿望、建议、命令、条件句等等。
虚拟语气和倒装
倒装的分类
完全倒装
例如，“Here comes the bus.”（公交车来了。）这句话中， 谓语“comes”完全提前到了句首。
部分倒装
例如，“Only in this way can we solve the problem.”（只 有这样，我们才能解决这个问题。）这句话中，情态动词“can” 提前到了主语“we”之前，但谓语“solve”没有提前。

）If you dropped/should drop/were to drop the glass,it would break.万一杯子掉下来会打碎的。
4） i f 的省略如果条件句中有were,had,should 等助动词，可将if 省略，而把were,had 或should置于句首,来表达以if 引导的条件句的相同意思。
例如：Should it rain/were it to rain tomorrow,the sports meet would be put off./Had he seen you yesterday,he would have returned your book.5)条件句或主句的省略当有上下文或上下句中的语言环境暗示的时候，表示虚拟语气的从句或主句往往可以省略，以避免重复。

Subjunctive mood(1) Nevertheless, should a fight follow, neither creature will be badly hurt, for the loser will save himself by makinga gesture of submission. (Line 5)(2) If it had not had this disability it would have undoubtedly stayed in the jungle and hunted for food in the customary way. (Line12)If the human population had not increased so rapidly, people would have had more space and freedom. (Line 23)(3) If the caged lion, for example, were free to wander on the grassy plains of Africa, it would be continually active, ranging over long distances, hunting in family groups. (Line 15)此三类句子体现了虚拟语气的三种时态变化。
（1）第1句中“should a fight follow”是表示将来情况的虚拟语气，意思为“if a fight should follow”，句中省略了“if”，将“should”提前，构成倒装，表示“万一，一旦”的意思。
值得注意的是本句中的主句部分未使用虚拟语气。
(2) 第二部分这两句是与过去事实相反的虚拟语气。
这类句子，从句用“had +动词过去分词”，主句用“would/should/could/might + have + 动词过去分词”。
(3) 第3句是与现在事实相反的虚拟语气。
从句用“did/were”，主句用“would/should/could/ might + 动词原型”。
虚拟语气专项复习：A．虚拟语气在非真实条件状语从句中的用法1、表示与现在事实相反的情况：if+主语+过去时+其他+主语+should/would/could/might+do+其他例：If I were you, I would take an umbrella.如果我是你，我会带把伞。
If I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。
If there were no air or water, there would be no living things on the earth.If I had any money with me, I could lend you some. 如果我带钱了，我就会借给你些。
（事实：没带钱）If he studied harder, he might pass the exam.如果他再努力些，就能通过考试了。
（事实：学习不用功）2、表示与过去事实相反的情况if+主语+had done +其他+主语+should/would/could/might+have done+其他例：If I had got there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。
If he had taken my advice, he would not have made such a mistake.3、表示对将来情况的主观推测①if+主语+did/should/were to do+sth.+主语+should/would/could/might+do+其他② if+主语+did/be(were)+sth.+主语+should/would/could/might+do+其他③if+主语+should+do+sth.+主语+should/would/could/might+do+其他例：If he should come here tomorrow, I should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。
If there were a heavy snow next Sunday, we would not go skating.If she were to be there next Monday, I would tell her about the matter.4、有时，虚拟条件句中，结果主句和条件从句的谓语动作不是同时发生时，①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。
如：If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会成为一个工程师了If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。
②从句的动作与现在事实相反，而主句的动作与过去事实不符。
如：If he were free today, we would have sent him to Beijing. 如果他今天有空，我们会已经派他去北京了。
If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。
③从句的动作与过去发生的情况相反，而主句的动作与现在正在发生的情况相反。
如：If it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的话，庄稼会长得更好。
If he had been working hard, he would be working in the office now. 要是他一直努力工作的话，他现在已进了办公室了。
5、当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即将were, should, had等词置于句首，这种多用于书面语。
如：Should he agree to go there, we would send him there. 要是他答应去的话，我们就派他去。
Were she here, she would agree with us. 如果她在这儿的话，她会同意我们的。
Had he learnt about computers, we would have hired him to work here.6、非真实条件句中的条件从句有时不表达出来，只暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句，在多数情况下，条件会暗含在短语中，如without…., but for….等But for his help, we would be working now. 要不是他的帮助，我们还会在工作呢。
Without your instruction, I would not have made such great progress. 要是没有你的指导，我不会取得如此大的进步。
We didn’t know his telephone number; otherwise we would have telephoned him. 我们不知道他的电话号码，否则我们就会给他打电话。
7、有时，虚拟条件句中，主、从句可以省略其中的一个，来表示说话人的一种强烈的感情。
①省略从句He would have finished it. 他本该完成了。
You could have passed this exam. 你应该能通过这次考试了。
②省略主句If I were at home now. 要是我现在在家里该多好啊。
If only I had got it. 要是我得到它了该多好啊。
B. 虚拟语气（Subjunctive Mood)的其他用法1、虚拟语气用在wish 后的宾语从句a、表示与现在事实相反的愿望，谓语动词用过去式eg. I wish I had your brains.我希望我有你那样的头脑。
(事实：我根本比不上你)b、表示与过去事实相反的愿望，谓语动词：had+done(动词过去分词）eg:.I wish I had known the truth of the matter.我希望我原来知道这件事的真相。
（事实：原来不知道）c、表示将来难以实现的愿望谓语动词：should/would + 动词原形eg. I wish I should have a chance again.我希望还能有一次这样的机会。
（事实：很难再有这样的机会了）(注：if only和as if/as though也有相同用法）2、虚拟语气用在目的状语从句中a.在for fear that, in case, lest引导的，若用虚拟语气时，从句谓语为：（should）+ 动词原形。
She examined the door again for fear that a thief (should )come in. 她又把门检查了一遍，以防盗贼进入。
He started out earlier lest he (should )be late. 他很早就出发了以防迟到。
b、在so that, in order that所引导的目的状语从句中，从句中的谓语为：can / may / could / might / will / would / should + 动词原形。
He goes closer to the speaker so that he can hear him clearer.He read the letter carefully in order that he should not miss a word.3、一想要(desire)二宁愿(prefer)三命令(order. command)四建议(advise. suggest. propose)五要求(demand. require. request. desire.insist)中，无论主句谓语动词为何种时态，从句的谓语动词都用：“should + 动词原形”或只用“动词原形”。
