一、如果what if是对现在情况的表达,不用虚拟语气,就用一般现在时【你的例句一】二、如果what if后面是对过去、将来的推测、假设,需要用虚拟语气 1、如果表示对将来的推测 有这几种用法: ①if+主语+were to do ②if+主语+should/would/could/might+do ③if+主语+did(动词过去式)/were (be动词都变were) 【你的后三个例句都是这种用法】 2、对过去事实的推测 If+主语+had done(过去完成时) →what If I had got a better job? 再问: 方便解释一下,虚拟语气吗 再答: Subjunctive Mood (虚拟语气) 非真实条件句的虚拟:(if从句比正常情况提前一个时态) (Ls。 15-16) It wouldn't be so bad if he’d let a taxman work on the forms with him, but he insists on doing it himself… 与现在事实相反: if用过去式或用should/were to 表示更小的可能性,主句用should/would/could/might+不定式。 I would have thought they were city fellows if I hadn’t seen the flying saucer stepped in。 与过去事实相反: if用过去完成式(had+done),主句用should/would/could/might+have done (完成体)再问: 请多给我一点what if 的例句。 再答: what happens if there is not any water in the earth。 如果地球上没有水了怎么办? 再答: What happens if Tom doesn't pass the exam?汤姆如果考试不及格,会怎么样? 祝你进步v再问: what if 主语 should 的例句有吗?
