15、状语从句，从句为非真实条件句。非真实条件句是指假设的条件及事实相反或不行能实现。当虚拟语气及如今事实相反时，从句用一般过去时。主句用should /would/could /might + 动词原形。1) If I had time , I would go for a walk. _2) If I were invited , I would go to the dinner party.（翻译）_3) If I won a million dollars in the lottery, I would put it in the bank. _2. He doesnt know if he

16、 should bring a present. 用法：1）此处if 表示“是否”，相当于 whether ，引导宾语从句。2)should 此处表示“ 应当”，不是用来表示虚拟语气。拓展：if 作“是否”讲，引导宾语从句，从句可以用一般将来时或其他时态。 if 作“假设”讲，引导条件状语从句，从句用一般如今时代替一般将来时。（翻译）1) I dont know if I should go to the party. _2) He doesnt know if we will arrive on time tomorrow morning._3) If I have enough money

17、 next year, I will go to England.3. I dont have a present , what if everyone else brings a present ?_用法：what if 表示“假设，怎么办？要是又怎样？”相当于What would happen if ? Eg: 1) What if its true ?_ 2)What if aliens should come to the earth ?_ _本单元语法学习： if 引导的非真实性条件状语从句 即 虚拟语气 通过动词形式的改变来表示说话人对发生的动作或存在的状态所持的看法或看法的动词形

18、式称为语气，虚拟语气表示说话人所说的话不是事实，而是一种祝福，建议或是及事实相反的假设等。 If 引导的条件状语从句分为真实和非真实条件句，非真实条件句应用虚拟语气。假设要表示及如今或将来事实相反时，其虚拟语气构造为：句 型条件从句主 句谓语动词形式动词过去式(be动词用were)would+动词原形 即：(从句)if +主语+动词过去式(be 动词用were), 一般过去时(主句) 主语+would+动词原形 过去将来时 如：If I had time, I would go for a walk.假设我有时间，我就会去漫步。(事实上我如今没有时间) If I were you, I wou
