高考英语语法——虚拟语气
高考英语语法之虚拟语气(一)语气的种类：英语句子中谓语动词的语气有四种：1. 陈述语气（The Indicative Mood）陈述语气用于直截了当地陈述事实、描述状态：He has publishedquite a number of essays this year .他今年已发表了好几篇论文。
2. 祈使语气（The Imperative Mood）祈使语气用于提出请求、命令、建议或是劝告等：Wait outside untilyou are asked . 请在外面等候，请你进再进去。
Let's just take abreak, shall we ? 我们休息一会儿，好吗？3. 疑问语气( the interrogative mood ) ：用来提出问题Where are you from?4. 虚拟语气（The Subjunctive Mood）虚拟语气用于表示主观愿望和假设的虚拟情况。
虚拟语气不太顾及事实的存在，它表现出说话人的主观因素比较多。
所以说话人所讲的内容往往是与事实相反的；或是其实现的可能性微乎其微，甚至于没有实现的可能性。
当然，有时为了使说话的语气客气、缓和、委婉，也使用虚拟语气。
If I had moremoney, I would buy a bigger apartment.我要是有再多一点钱，我就买一套更大一些房子。
(二) 虚拟语气的种类：虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
虚拟语气在条件句中应用比较多；条件句可分为两类，一类为真实条件句，一类为非真实条件句。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
1.真实性条件句①真实条件句用于陈述语气，假设的情况有可能发生,各种结构如下：条件从句主句一般现在时 shall/will + 动词原形祈使句情态动词一般现在时If he comes, hewill bring his violin. 如果他来，会带小提琴来的。

高考虚拟语气
高考虚拟语气是指在表达虚拟情况或假设的时候所使用的语气，与实际情况不符合。
下面是对高考虚拟语气的解释和用法：
在高考英语中，虚拟语气常常出现在条件句中，表示与事实相反的假设或不可能实现的愿望。
虚拟语气通常由动词的过去式（一般过去式、过去完成时）或“would”引导。
虚拟语气的用法主要有以下几种情况：
1. 虚拟条件句（If 条件句）：
如果现在条件与事实相反，用虚拟语气表示。
例子：If I were you, I would study harder.（如果我是你，我会
更加努力学习。
）
在这个例句中，使用了虚拟语气“were”表示与现实相反的假设
情况。
2. 虚拟愿望句：
表示与现在事实相反的愿望，用虚拟语气表示。
例子：I wish I had studied harder for the exam.（我希望我当时
能更努力地学习考试。
）
这句话中使用了虚拟语气“had studied”表示与现实相反的假设
情况。
3. 虚拟建议句：
表示与现在事实相反的建议，用虚拟语气表示。
例子：I suggest that she go to the library to study.（我建议她去
图书馆学习。
）
这个例句中使用了虚拟语气“go”表示与现实相反的建议情况。
总之，高考虚拟语气在英语考试中常常出现，需要我们掌握相关的用法和规则，并能正确运用。
只有熟练掌握虚拟语气的使用方法，才能在高考中取得更好的成绩。

虚拟语气的详细讲解
高考英语之虚拟语气--冯氏英语虚拟语气语气就是我们常说的说话人说话的口气。
在汉语中，语气是由说话人说话的语调，情节等等表现出来的，动词不变。
而在英语中，除了语调之外，最主要的是动词发生变化而表示不同的语气。
在英语中语气分类为三类：陈述语气，祈使语气和虚拟语气。
陈述语气: 我们把一句话作为对情况的叙述或询问说出来，就用陈述语气，用于陈述句，疑问句和感叹句。
祈使语气：我提出劝告，请求，命令等时，要用于祈使语气虚拟语气：如果我们所说的不是事实，也不是要求命令，劝告等。
而上一种假设，愿望，建议或是一种难以实现的空想，就用虚拟语气。
虚拟语气主要分为三个板块：1. 条件句（if）如：If I were at there, I would give him a hand. 如果我在那儿的话，我会帮他的。
2. 其他从句【主从；宾从；定从；同从；状从（目的；方式；让步）】（主从）如：It is important that we should speak politely. 说话要有礼貌，这是很重要的。
(并不是每时每刻都能保证说话有礼貌，总有犯错的时候，所以这种说法可能性很小。
)（宾从）I wish I should have a chance again. 我希望我还能有一次这样的机会。
（但这种机会不会再有了或这种机会太小了；与现在事实相反）（定从）It is time we had dinner. 我们该吃饭了。
（现在该吃饭的时间，但我们还没吃；与现在事实相反。
）（同从）Where did you get the idea that I could not come? 你在哪儿听说我不能来？（虽说主句是过去时，但从句描述的是现在我已经到了，从句与现在事实相反。
）（目的状语）I say all this, lest there be a misunderstanding.我说所以这些，以免产生误解。
（我担心会产生误解，但事实上没发生；与现在事实相反。

（if 条件句是对过去的虚拟），而主句是对现在的虚拟。
