9、or, please。请打开门。(3)虚拟语气: 表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。如: If I were you, I should study English. 如果我是你，我就学英语了。May you succeed! 祝您成功！二、虚拟语气在条件从句中的用法 条件句有两类，一类是真实条件句，一类是虚拟条件句。如果假设的情况是有可能发生的，就是真实条件何。在这种真实条件句中的谓语用陈述语气。如: If it doesnt rain tomorrow, we will go to the park. 如果明天不下雨，我们就去公园。如果假设的情况是过去或
10、现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天见到你，他会问你这件事的。(事实上他昨天没见到你，因此也未能问你这件事。)在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气。现将虚拟条件从句和主句的动词形式列表如下:从 句主 句与现在事实相反动词的过去式（be的过去式一般用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
11、 + have + 过去分词与将来事实相反 动词过去式，should + 动词原形，were to + 动词原形would/ should/ could/ might + 动词原形注: 主句中的should只用于I、we，但在美国英语中，should常被would代替；从句中的should 可用于各种人称。l. 表示与现在事实相反的假设和结果。如: If my brother were here, everything would be all right. 要是我哥哥在这儿, 一切都没问题了。 2. 表示与过去事实相反的假设和结果。如: If you had taken my advice，
12、you wouldnt (couldnt) have failed in the exam. 如果你按照我的建议去做，你一定不会(不可能)考试不及格。3. 表示与将来事实可能相反的假设和结果。如: If it were Sunday tomorrow, I should (would，could，might) go to see my grandmother. 如果明天是星期天，我就 (可能)去看望我奶奶。If it were to snow this evening, they would not go out. 如果今晚下雪，他们将不出去了。4. 在条件句中如果出现were, had, s
