if条件句中的虚拟语气讲解

虚拟语气(一) 一、考点聚焦 1、虚拟语气用于条件状语从句中 If I were a boy, I would join the army. If she had time, she should go with you. If h e had taken my advice, he would have succeeded in the competition. If i t were to rain tomorrow, the football match would be put off. If I had time, I would attend the meeting. If he had hurried ,he could have caught the train. If I were to go abroad ,I would go to America 如果我是你，我就会努力学习 If I were you, I would work harder at my lessons. 如果我知道他的电话号码，我就给他打电话了 If I had known his telephone number, I would have called him. 如果明天下雨的话，我们会取消比赛． If it should \were to rain, we would call off the match.

使用虚拟条件句要注意的几点： １．当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为：错综时间条件句“，动词的形式要根据它所表示的时间作出相应的调整． If you had followed my advice , you would be better now. 如果你听我的建议，你现在就会痊愈了． If you had studied hard before, you would be a college student now. 如果你努力学习的话，你现在就会是大学生了． If they had worked hard, they would be very tired now.(从句说的是过去，主句指的是现在) ２．省略句 在条件句中，可省略if，把were ,had, should 提到句首，变为倒装句式．If I were at school again, I would study harder. Were I at school again, I would study harder. If you had come earlier, you would have met him. Had you come earlier, you would have met him. If it should rain tomorrow, we would not go climbing. Should it rain tomorrow, we would not go climbing. Were I a boy, I would join the army. Had he taken my advice, he would have succeeded. Were it not for the expense, I would go to Britain. 2、虚拟语气用于名词性从句 （1）虚拟语气在宾语从句中的运用。 ①“wish + 宾语从句”表示不能实现的愿望，译为“要是……就好了”等。 表现在过去时 表过去过去完成时 表将来would, might, could＋动词原形 I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. I wish (that) I were a bird. I wish (that) I had seen the film last night. I wish (that) I would\could go.

If条件句和虚拟语气

If条件句和虚拟语气 if 条件句和虚拟语气 包含条件从句的句子叫条件句。条件句有两类：一类是真实条件句（First conditional）,一类是非真实条件句(Second Conditional)。如果假设的情况是有可能发生的，就是真实条件句；如果是纯属假设情况或是不可能发生或可能性不大的情况，则是非真实条件句。 1.真实条件句,可用if和unless引导 1）一个动作发生，另一动作随之发生 I’ll lend Peter the money if he needs it. If he has time, he will come. If he doesn’t come before 12 o’clock, we won’t wait for him. I shall go tomorrow unless it rains. I won’t go to her party unless I am invited. 2）表示命令、建议或请求,这时的if等于when If she telephones, let me know. Give my love to Lawrence if you see him. 3)will用于if从句中，不表示将来，而表示愿意或坚持的意思 If you will come this way, I’ll take you to the manager’s office. If you will get drunk every night, it’s not surprising you feel ill. 2. 非真实条件句

非真实条件句包括虚拟条件句和错综时间条件句 1）虚拟条件句分三类，其结构列表如下： If I become president, I’ll make all of my people live a happy life. (竞选总统的候选人这样说) If I became president, I’d make all of my people live a happy life. (一个小学生这样说) l 以下与现在事实相反 He wouldn’t feel so cold if he were indoors. I am sorry I am very busy just now. If I hade time, I would certainly go to the movie with you. l 以下与过去事实相反 If you had come here a little earlier, you would have met the pop star. I don’t know what would have happened if Jane hadn’t been able to speak Japanese. l 以下推测将来 If I were to do the work, I should do it in a different way. If it should rain again, what else could we do? 2) 错综时间条件句

(完整版)if引导的非真实性条件状语从句即虚拟语气

if 引导的非真实性条件状语从句即虚拟语气 通过动词形式的变化来表示说话人对发生的动作或存在的状态所持的态度或看法的动词形式称为语气。.英语中的语气分三种：陈述语气、祈使语气、虚拟语气。虚拟语气表示说话人所说的话不是事实，而是一种祝愿，建议，与事实相反的假设或实际可能性不大的情况等（即非真实的假设）。 If 引导的条件状语从句分为真实和非真实条件句（虚拟条件句）。真实条件句表示在假设的条件下，有可能实现的情况。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。 If he does n’t hurry up, he will miss the bus.( 真实条件状语) If he was free, he asked me to tell stories.（真实条件状语） If I were you, I would go at once.（非真实条件状语从句） If there was no air, people would die.（非真实条件状语从句）1）非真实条件句中虚拟语气的基本形式。 假设类型条件从句的动词结果主句的动词 与现在事实相反动词过去式（be只用were）would/should/could/might + 动词原形 与过去事实相反had+过去分词would/should/could/might + have + 过去分词 与将来事实相反动词过去式/(should/were to)+动词原形would/should/could/might + 动词原形

if条件状语从句中虚拟语气

if条件状语从句中的虚拟语气 一、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。 1. “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 students. ⑶、If it should snow tomorrow, they couldn't go out. 2、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。 二、虚拟语气在if 引导的条件句中的用法： 1. If it weren’t for your help, we would get into trouble. 如果没有你们的帮助，我们就会陷入困境。（而事实上得到了你们的帮助） 2.If the weather were fine, I would go there. 如果天气好，我去那儿。（事实天气不好） 3.If I were you, I would read it again. 如果我是你的话，我再读一遍。（事实上我不是你） 4.If time permitted, I would write it again. 如果时间允许的话，我再写一遍。（事实上时间不允许） 5.If it weren’t snowing, we wouldn’t stay in the house. 要是现在不下雪的话，我们就不会待在屋里。（事实上现在下雪） 6.What would I do if I were in your place?要是我处于你地位我会怎么办？（事实上我不在你的位置上） 7.If he hurried, he could catch the first bus. 他要是快点能够赶上头班公共汽车。（可是他不着急） 8. If I were you, I should buy it. (从句用过去式动词were，主句用动词原形buy) 9. If I had time, I would study French. (如果有时间，我会学习法文。)（从句用过去式动词had，主句用动词原形study） 10. If she knew English, she would not ask me for help. (如果她懂英文，她就不必要我帮了。)(从句用过去式动词knew, 主句用动词原形ask) 注意：如果动作在进行中，主句要用："主语+ would be + 进行式动词+ ……" 14. If they were here, he would be speaking to them now. (从句用过去式动词were, 主句用would be speaking)
