虚拟语气语法填空专题 考点一 虚拟语气在条件状语中的使用 真题体验 1. _____ (were) it not for the support of the teachers, the student could not overcome her difficulty. 2. If you _____ (come) yesterday, you would have met that famous star. 3. We _____ (not be) in such a difficult situation now if we had taken your advice earlier. 4. _____ (should) it rain tomorrow, we would have to put off the sports meeting. 知识点拨 一、虚拟语气在if条件句的应用 if条件句 从句的谓语形式 主句的谓语形式 表示现在 动词过去式(be的过去式用were) should/would/could/might＋动词原形 表示过去 had＋过去分词 should/would/could/might＋have＋过去分词 表示将来 should＋动词原形；were to＋动词原形 should/would/could/might＋动词原形 二、错综条件句 主句与从句动词发生时间不一致，动词形式要根据发生时间作出相应调整。比如从句表示过去，主句表示现在，从句用had done，主句用should/would/could/might +动词原形。 三、if省略句 含有had/were/should的虚拟条件句中省略if，将had/were/should放在主语之前，构成部分倒装。 四、含蓄条件句 假设条件隐含在词或短语或上下文，常见的有：but for（要不是）、otherwise（否则）、without（没有）等，句子要用虚拟语气。 即时演练 1.
