高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。
这种句子称为含蓄条件句。
例如：But for the help from you ， I would not have had the chance to go to college.二、虚拟语气在某些从句中的运用在某些词或短语后接的从句中要使用虚拟语气，表示愿望、建议或命令等。
根据虚拟语气的形式不同，虚拟语气可以分为“should类”和“过去时态类”。
（一）should类这一类的虚拟语气是通过从句中的谓语动词使用“should +动词原形”体现出来的，should可以省略。
其具体运用体现在：1. 在suggest ， order， demand ， propose， command， request， desire，insist等表示建议、命令、要求、意见的动词后接的宾语从句中要使用虚拟语气。
如：He suggests that she should leave the house at once.The leader ordered that the task（should） be finished as soon as possible.He proposed that we （should）deal with the problem by the view of development.2. 与suggest，order，demand，propose，command，request，desire，insist等动词相对应的名词suggestion，order，demand，proposal等后的表语从句或同位语从句中要使用虚拟语气。
如：The general sent the order that the battle （should）be held on until the complete failure of the enemy.My proposal is that we（should） set a deadline for handing in the plan.3. 在It is/was suggested （ordered，demanded，proposed，etc.）结构以及necessary，essential，important，strange，natural等形容词后的主语从句中要使用虚拟语气。
如：It’s requested that we （should）keep the stability of the society for the people’s peaceful life.It is necessary that the badly wounded man（should） be treated immediately. （二）过去时态类英语中，还有一些词或短语后接的从句或句子，也要使用虚拟语气，虚拟语气是通过句中的谓语使用过去的某种时态（如：一般过去时、过去完成时等）来体现的。
1. wish，would rather 后的宾语从句。
如：He wished he had never been involved in such affairs.I would rather you could teach me again.2. as if，as though引导的从句。
如：The little boy knows so many things as if he was a man.He acted as usual as though nothing had happened.3. 由if only （要是……，那该多好啊！）引导的惊叹句。
如：If only I had passed the test！If only it stopped raining！4. It is（about/high） time 后的定语从句。
如：It is time we went out for a walk.It was high time they had begun to prepare the experiment.三、虚拟语气的其它用法在英语中，一些表示建议、请求、劝告、愿望、祈祷、祝福或诅咒的句子，也需要使用虚拟语气。
如：Would you mind smoking here？May you be lucky！Long live the people of China！God save me.虚拟语气练习题1．If Wu Dajing _____ the record in 2018 Winter Olympics. he would not be world famous now. A．hadn't brokenB．hasn't brokenC．didn't breakD．doesn't break【答案】A【解析】【详解】考查虚拟语气。
句意：如果2018年武大靖没有打破世界纪录，他现在就不会世界闻名。
本句考查了条件状语从句虚拟语气中的错综条件句，if从句与过去事实相反，所以用过去完成时，主句与现在事实相反，用“情态动词+动词原形”。
故A项正确。
2．––What a journey! We’ve finally arrived!––_____ an out-of-date train schedule, we would not have missed the train.A．Had we not used B．Did we useC．If we didn’t use D．If we had used【答案】A【解析】【详解】试题分析: 句意：真糟糕的旅行！我们终于到了。
如果我们没有用过期的列车时刻表，我们就不会错过火车了。
根据后句中的would not have missed可知句子使用了虚拟语气，是对过去发生的事情进行假设，主句应该用过去完成时，当句中有had ，should ，were时，可以省略if，把这些词提前，构成倒装结构，选A。
考点：考查虚拟语气3．It is requested that the reporter ________ to blame for the wrong report.A．referring to B．referring to asC．referred to be D．referred to being【答案】C【解析】【详解】试题分析：考查虚拟语气和过去分词做定语：句意：据要求被提到的记者要为错误的报告道歉。
refer to “提及”和reporter之间是被动关系，故用过去分词作定语。
request 是“要求”， It is requested that后加主语从句时从句用虚拟语气，should可以省略；谓语用be动词原形，省略should，所以选C。
考点：考查虚拟语气和过去分词做定语4． it rain tomorrow, we would have to call off the hike.A．Will B．Would C．Should D．Were【答案】C【解析】【详解】试题分析：句意：如果明天下雨，我们将取消这次徒步旅行。
表示对将来情况的虚拟。
从句：①if+主语+were to do ②if+主语+should+do ③if+主语+过去式（be动词用were），主句：主语+should/would+do。
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，即把were,should,had等词置于句首，选C。
考点：考查虚拟语气5．—It's a pity that Andrew didn't want to go to the conference.—________ willing to go，we could have paid all his expenses.A．Had he been B．BeingC．Was he D．He had been【答案】A【解析】【详解】A解析考查虚拟语气与倒装。
根据第一句中的时态可知此处是对过去情况的虚拟，意思是“如果他愿意去，我们会支付他所有的费用”。
此处是省略了虚拟条件句中的if而引起的倒装，其正常语序应为“If he had been willing to go”。
6．Nancy was very disappointed to hear the news. I wish I her about that.A．hadn’t told B．didn’t tell C．wouldn’t tell D．can’t tell【答案】A【解析】【详解】试题分析：考察虚拟语气。
