if引导的条件句中的虚拟语气

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 h is 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。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就是： ①与过去事实相反，在从句中用过去完成时形式表示。 ②与现在事实相反，在从句中用过去一般时形式表示。 ③与将来事实可能相反，在从句中用过去将来时形式表示。 主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。例： ⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my stud ents. ⑶、If it should snow tomorrow, they couldn't go out. 4、注意事项 ①if条件句中如有were, should, had，可以省去if，并使用倒装语序。 ②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。

Unit 4 一. if 条件句 if可以引导真实条件句和虚拟条件句。真实条件句表示在假设的条件下，能够实现的情况。在这种情况下，主句和从句的谓语动语随各自的人称和时态发生变化，同时if条件句遵循“主将从现”的原则，即主句用一般将来时，从句用一般现在时表将来。 If it doesn’t rain tomorrow, we will go for a picnic. 如果明天不下雨，我们去野餐。 如果if条件句用来描述说话人认为与事实相反的内容，或仅是一种愿望，假设、猜测等，我们称为虚拟条件句。 If I got rich , I would travel around the world. 如果我有钱了，我将周游全世界。 二.虚拟语气 区分条件从句主句例句 ★与现在事实相反If+主语+过去 式（be多用 were）… 主语+would/should/could/ might+动词原形… If I were rich, I would buy a big house. 如果我 有钱，我将买一所大房 子。 与过去事实相反If+主语+had+ 过去分词… 主语 +would/should/could/might+ have+过去分词… If I had read this article earlier, I would not have made this kind of mistake.如果我早读过这 篇文章，我就不会犯这 样的错误了。 与将来事实相反If+主语+过去 式（be多用 were） /should+动词 原形/were to+ 动词原形… 主语 +would/should/could/might+动 词原形… If it were to rain tomorrow, the match would be put off. 如果明 天下雨，比赛就会被推 迟。

if引导的一般条件句

If 引导的一般条件状语从句 条件状语从句 概念：在复合句中，由从句表示的状语叫做状语从句。它可以用来修饰主语中的动词.形容词.副词等。根据它表达的意思，状语从句可以分为时间状语从句，地点状语从句，条件状语从句，比较状语从句，目的状语从句，结果状语从句和让步状语从句等。由连接词if或unless引导的状语从句叫做条件状语从句。（注意：在含有条件状语从句的复合句中，如果主句是一般将来时态，从句要用一般现在时[主将从现原则]) 经典语句：If it doesn't rain tomorrow, we will go to the zoo. If you open the door，I will come in. if 引导的条件状语从句 主句用一般将来时，if 从句用一般现在时。 We will go to the park if it is fine tomorrow.如果明天天好的话我们就去公园。 We will go traveling if we have time tomorrow.如果明天我们有时间我们就去旅行。 主句祈使句，if 从句用一般现在时。 Please call me if you need help. 如果你需要帮助请打电话给我。 Sing a song if you feel happy. 如果感到快乐就唱首歌吧！ 主句含有情态动词，if 从句用一般现在时。 Y ou can make a lot of money if you run a company.如果你经营一家公司的话你会装很多钱。 Y ou can get number one if you study hard. 如果你努力学习你就可以得第一。 —Mary, what about going boating if it doesn’t rain? 玛丽，如果明天不下雨，我们就划船好吗？ —Good idea. 好主意。 1、主将从现：主语将来时，从句一般现在时，例：If it is rainy tomorrow，（从句）I will stay at home。（主句） 2、虚拟：主句用would do，从句用过去式，具有假设性，一定不会是真的，例如“如果我是你，我不会穿那条裤子”If I were you，I would not wear the pants。我永远都不可能是你，所以是具有假设性的，还有“如果你有一百万，你会怎么做？”突然天降横财机率是很小的，所以也是具有假设性的，像这种几乎不可能发生的事或者根本不会发生的事就用虚拟！ 条件状语从句和主句还有一个共同的伙伴，有时它可以替代从句和主句，它就是“祈使句+and / or+简单句”。其中and表示句意顺承；or则表示转折，意为“否则”。例如： If you work harder, you’ll pass the exam. = Work harder, and you’ll pass the exam. 如果你再努力些，你就会通过考试。 If you don’t hurry up, you’ll miss the train. = Hurry up, or you’ll miss the train. 如果你不快点儿，你就赶不上火车了。 在学习条件状语从句时，同学们要注意以下几点： 一、时态 如果主句是一般将来时态，这时从句不可以用将来时态，而要用一般现在时。例如： I won’t go there with you if it rains tomorrow. 如果明天下雨的话，我就不和你一起去那儿了。 二、主从句的位置 大多数情况下，从句可以位于主句之前，也可以位于主句之后。不过从句在前时，主从句之间必须用逗号隔开。例如： Please tell me if he comes back. = If he comes back, please tell me. 如果他回来了，请告诉我一声。

16 if 引导的真实条件句

if 引导的真实条件句 真实条件句 真实条件句用于陈述语气，假设的情况可能发生，其中if 是如果的意思。 句式为（if + 从句，+主句）。中文意思是“如果某事发生（或不发生），另一事就（不）发生”。 主句：即句子的主体,能单独使用或出现的句子 从句:是复合句中不能独立成句，但具有主语部分和谓语部分 主将从现：主句将来时（一般将来时、将来进行、祈使句），从句现在时（一般现在、现在进行、现在完成） 祈使句表示对别人将来的请求、命令、建议等等 祈使句可以用语气词“吧”作结尾，也可以不用语气词。 祈使句无主语, 主语常省去。 真实条件句

1. if从句和主句都用一般现在时，表示客观真理或习惯和持续发生的事情。如： If the moon goes near the earth, the tide [taid] goes high. 如果月亮离地球距离近，潮水就高。 2. if从句用一般现在时，主句用一般将来时，表示从句中的动作如果发生，那么主句中的动作也将发生。如： If it stops raining later this afternoon, we will eat out. 如果今天下午晚些时候雨能停，我们就出去吃饭。 3. if从句用一般现在时，主句用祈使句，表示给某人提建议或命令某人做某事，及提出建议或请求。如： If you are not likely [?laikli] 可能的to be in town, please let me know. 如果你不可能在城里，请让我知道。 注意： 1）在真实条件句中，主句不能用be going to表示将来，该用shall, will. 2）表示真理时，主句不用shall (will) +动词原形，而直接用一般现在时的动词形式。
