高中英语语法造句英语写作if条件句虚拟条件句(高级)

if虚拟语气的用法归纳IF虚拟语气是英语中的一种重要语法现象，主要用于表示与现实相反的假设、愿望、建议等。

它分为两种形式：if条件句和if非条件句。

以下是对IF虚拟语气用法的详细介绍：一、if条件句1. 表示与现在事实相反的假设：If + 主语+ 过去时态，主语+ would/could/might/should + 动词原形。

例如：If I were you, I would go to the party.（如果我处在你的位置，我会去参加派对。

）2. 表示与过去事实相反的假设：If + 主语+ had done，主语+ would/could/might/should + have done。

例如：If he had come to the meeting, he would have known the plan.（如果他参加了会议，他就会知道这个计划。

）二、if非条件句1. 表示建议、劝告：主语+ should/would/might/ought to + 动词原形。

例如：You should go to the party.（你应该去参加派对。

）2. 表示愿望：主语+ could/would/might + 动词原形。

例如：I wish I were a bird.（我希望我是一只鸟。

）3. 表示假设：If + 主语+ 动词过去式，主语+ would/could/might + 动词原形。

例如：If I had time, I would go to the park.（如果我有时间，我会去公园。

）三、if虚拟语气的特殊结构1. 省略if，将were、had、should等词置于主语之前：主语+ were/had/should + 动词原形。

例如：She were here, she would meet him.（如果她在这里，她会见到他。

）2. 使用倒装结构：were/had/should + 主语+ 动词原形。

英语动词有三种语气：陈述语气、祈使语气、虚拟语气（用来表示说的话不是事实，或者是不太可能发生的情况，而是一种愿望，建议，假设的语气叫虚拟语气。

）虚拟语气的考点：1•条件句中的虚拟语气的用法；2.条件句中虚拟语气的倒装；3•名词性从句中虚拟语气的用法；4•几种特殊结构中虚拟语气的用法；5.虚拟语气时态的判定。

一、If引导的虚拟条件句区别：If it rains tomorrow，the crops will be saved.陈述语气If it rained tomorrow，the crops would be saved.虚拟语气真实条件状语从句与非真实条件状语从句真：eg .If he doesn' hurry up, he will miss the bus.如果他不快点，他将错过巴士。

（真实条件状语）（不是虚拟语气）If he is free, he will ask me to tell stories.如果他是空闲的，他会要求我讲故事。

（真实条件状语）（不是虚拟语气）非真：eg. If I were you, I would go at once.如果我是你，我马上就会去。

（非真实条件状语从句）二、虚拟语气在条件从句中：【例句】1.If you had come a few minutes earlier，you would have met him.要是你早来几分钟的话，你就能见到他了。

（与过去事实相反）2.lf it were sunny tomorrow, i would come to see you.明天要是天气好的话，我来看你。

（与将来事实可能相反）3.lf i were you, i would go at once.假如我是你的话，我会马上走。

（与现在事实相反，事实上我不可能是你）主从句的谓语形式（一）与现在事实相反的虚拟条件句表示与现在事实相反的情况，例 1.lf I were you, I would take an umbrella.如果我是你，我会带把伞。

本文将对虚拟语气的用法进行总结和归纳。

一、虚拟语气的用途虚拟语气用于表现非真实情况或不可能实现的愿望、条件、建议、怀疑、命令、警告等。

主要分为以下几种情况：1. 虚拟条件句：表示与现实相反的情况。

例如：If I were you, I would study harder.（如果我是你，我会更加努力学习。

）2. 虚拟愿望句：表示与现实相反的愿望。

例如：I wish I could go on a vacation.（我希望我能去度假。

）3. 虚拟建议句：表示对现实的建议。

）2. 虚拟语气在动词的形态上表现为"were"而不是"was"。

例如：If I were you, I would apologize.（如果我是你，我会道歉。

）3. 虚拟语气在情态动词的用法上表现为"should" + 动词原形。

if引导的条件句中的虚拟语气虚拟语气表示一种不能实现的假设。

该语法主要用于if条件状语从句。

一、if引导的条件状语从句的分类及虚拟条件句的判断1、可以把条件句分为两类：1).真实条件句（Sentences of Real Condition）：凡是假设的情况发生性可能很大，就是真实条件句。

例如：⑴、If I have time , I will help you with this work.如果我有时间会帮助你做此工作的。

(2)、If time permits, we'll go fishing together.(如果有时间的话，我们就一起去钓鱼。

）2).虚拟条件句（Sentences of Unreal Condition）：当假设是不大可能实现时，就是虚拟条件句。

例如：⑴、If I were you , I would have attended the meeting. 如果我是你的话，就去参加会议了。

⑵、If he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话，就会看见他的老朋友。

⑴、If it had rained yesterday, we would have stayed at home.（如果昨天下雨的话，我们就会留在家里。

）2、.if条件状语从句中虚拟语气的判断判断是真实条件句还是非真实条件句。

只有在非真实条件句中才使用虚拟语气。

通过句子意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。

判断这个假设是与哪个事实相反。

通常有三种情况：①与过去事实相反。

②与现在事实相反。

③与将来事实可能相反。

3、“后退一步法”后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。

if 条件句虚拟语气虚拟语气是英语语法中的一种特殊语气，用来表示与事实相反或假设的情况。

混合时间虚拟条件句一般情况下，在虚拟条件句中，if引导的从句中，谓语动词表示的动作与主句谓语动词表示的动作发生的时间是一致的，即同为将来，现在或过去，此时主从句虚拟的时间是相同的。

有时候，条件从句表示的动作和主句表示的动作，发生的时间是不一致的，这时，从句和主句各自的谓语动词形式要根据它们各自动作发生的时间作调整，构成混合虚拟条件句。

一.典型例句1. If you had studied hard before, you would be a college stud ent now.（从句与过去事实相反，主句与现在事实相反。

）2. If you had asked him yesterday, you would know what to d o now.（从句与过去事实相反，主句与现在事实相反。

）二.解题方法找出主从句中的时间状语，然后根据各自的时间找出所对应的谓语形式。

条件句和虚拟语气的高级运用条件句和虚拟语气是英语语法中重要的一部分，它们被广泛应用于日常交流和各类写作中。

借助条件句和虚拟语气的高级运用，我们可以表达不同的假设、愿望、建议和反悔等情态。

本文将对条件句和虚拟语气的高级运用进行详细介绍。

一、条件句的高级形式1. 倒装条件句倒装条件句是指将主语和谓语的位置颠倒的条件句形式。

在实际运用中，倒装条件句通常用于表示某种无法实现的假设、虚构的情境或明显偏离现实的情况。

例如：Had I known the truth, I would have acted differently.（如果我当时知道真相，我会采取不同的行动的）在这个例子中，句子中的主谓位置颠倒，形成了倒装条件句，用于表达过去某个条件没有实现的情况。

2. 与现实相反的条件句与现实相反的条件句用于表达与事实相反的假设情况。

它由两个分句构成，其中一个表示与现在或将来事实相反的情况，而另一个表示这个与现实相反的情况的条件。

例如：If I were a bird, I would fly freely in the sky.（如果我是一只鸟，我将自由地在天空中飞翔）在这个例子中，条件句中的虚拟语气表达了一个与现实相反的情况，即作者并非一只鸟，但如果是的话，他会飞翔。

二、虚拟语气的高级运用1. 愿望与建议虚拟语气常用于表达愿望、建议和要求等情态。

具体地说，当我们希望某件事情发生或提出建议时，可以使用虚拟语气来表达。

例如：I wish I had studied harder when I was in school.（要是我在学校时努力学习就好了）在这个例子中，作者后悔自己在过去学习不够努力，希望事情发生的情况是与过去的事实相反的，因此使用了虚拟语气。

2. 虚拟条件虚拟条件是指表达一种假设情况下所产生的结果。

当我们要表达与现实相反的条件时，可以使用虚拟语气的虚拟条件形式。

例如：If I had taken the earlier flight, I would have arrived on time.（如果我坐早一班飞机的话，我会准时到达）在这个例子中，作者表达了一个与现实相反的条件，即他并没有坐早一班飞机，但这个条件下的结果是他会准时到达。
