If it should rain tomorrow, I would stay at home. 如果明天下雨，我会待在家里。 → Should it rain tomorrow, I would stay at home.

Otherwise, I would have taken part in the sports meeting. 那天我病了。否则，我就参加运动会了。 Without water, fish could die. 离开水，鱼儿就会死掉。 But for your help, we could not have succeeded. 要不是你帮忙，我们就不会成功。 考点一 非真实条件状语从句中的虚拟语气 专题十九 虚拟语气 1. —He failed in the exam again. —He his teacher's advice. A. mustn't follow B. must follow C. had been kept D. should have followed 【解析】考查虚拟语气。根据第一句He failed in the exam again（他考试又不及格）可知，是发生在过去的事情，表示与过去事实相反的虚拟语气用should have+过去分词形式。句意：——他考试又不及格。——他早就应该听老师的建议。故选D。 2. If I were you, I start to work right now. A. can B. would C. will D. had 【解析】考查虚拟语气。虚拟语气表示与事实相反的假设。与现在事实相反的虚拟语气的构成为：If+主语+动词过去式（be动词用were）, 主语+should/would/might/could+动词原形。根据题干中的I were you可知，是与现在事实相反的虚拟语气，主句用“主语+should/would/might/could+动词原形”结构。句意：如果我是你，我立刻就开始工作。故选B。 考点精讲 D 典例剖析 专题十九 虚拟语气 B 3.
