高中冀教版高中英语语法全全解 【寒假专版】 A版知识点全解 寒假专版 虚拟语气系统讲解 特殊结构与综合语法 考频分析 冀教版高中特殊结构与综合语法中，虚拟语气是重要语法点，考频占句法总量的15%左右，涉及 试卷多个核心题型：单项选择3-4题、完形填空2-3题、语法填空2-2题、书面表达（关键考察，直 接影响语气表达的准确性与得体性)。在情境假设类题目中，虚拟语气的时态对应及语境适配往往 是解题关键。 考查内容 。基本句型结构：与现在事实相反(if+一般过去时，主句would/could/might+-动词原形)、与过去事 实相反(if+过去完成时，主句would/could/might+-have+过去分词)、与将来事实相反(if+一般过 去时were to do/should do,主句would/could/might+-动词原形)的句式构成 。特殊句式应用：wish后的宾语从句（现在用过去时，过去用过去完成时，将来用would/could+-动词 原形)、as if/though引导的从句（根据语境选用相应时态）入、if only引导的感叹句（用法同wish) ·情态动词的虚拟用法：should+动词原形用于suggest/insist/demand等词后的宾语从句(should可省 略)、would rather后的从句（现在/将来用过去时，过去用过去完成时） 知识点一：虚拟语气的基本概念及语气类型 1.虚拟语气的定义（表达非真实或假设情况） 1.核心功能：表示与事实相反的假设、主观愿望、建议、推测或不可能实现的情况 2.例句： ·If I were you,I would take the job.(与现在事实相反的假设) 。I wish I could fly like a

game yesterday. 答案：would have lost 解析：由but for-+名词'及时间标志词'yesterday'可知，隐含与过去事实相反的假设，主句用”would have+过去分词”，lose的过去分词为lost。 真题2（单项选择)： She was too tired,otherwise shepart in the activity with us A.takes B.took C.will take D.would take 答案：D 解析：由副词'otherwise'”(否则)可知，隐含与现在事实相反的假设，主句用'would:动词原形”， take用原形。 考法二：含蓄虚拟与混合虚拟的综合应用 核心：识别无f引导的含蓄虚拟条件，结合主从句时间不一致的混合虚拟结构，判断正确时态 真题1（语法填空）： But for the heavy rain,we_(arrive)at the destination an hour ago 答案：would have arrived 解析：由含蓄虚拟标志词'But for'”可知此处表假设，”an hour ago'”提示与过去事实相反，主句用”would have+过去分词'，arrive的过去分词为arrived。 真题2（单项选择）： If you_the medicine yesterday,you_better now. A.took would feel B.had taken would feel C.took will feel D.had taken would have felt 答案：B 解析：从句'yesterday'提示与过去事实相反，用过去完成时had taken”;主句'now'提示与现在事 实相反，用woud+动词原形'，构成混合虚拟结构。 考法三：虚拟语气在复合句中的综合应用 核心：结合条件句、名词性从句及含蓄虚拟结构，根据语境判断虚拟时间和对应时态，掌握多结构 混合的虚拟语气用法 真题1（单项选择)： If she-here now,she would suggest that we-the meeting immediately. A.were start B.was start C.were should start D.was should start 答案：A 解析：前半句为与现在事实相反的条件句，be动词用were;后半句为suggest后的宾语从句，需用 5 高中冀教版高中英语语法全全解 【寒假专版】 A版知识点全解 (shoul d+动词原形，should可省略，故选A。 真题2（语法填空）： But for your help,we_(not finish)the task yesterday.Our teacher suggested we_(have)a celebration then. 答案：wouldn't have finished have 解析：第一空由but for+名词”及时间标志”yesterday”可知为与过去事实相反的含蓄虚拟，结构为 would have done;第二空为suggest后的宾语从句，用(should)+动词原形，should可省略。 解题小妙招 虚拟语气妙招 含蓄虚拟看隐含，but for/otherwise是关键： 过去事实用“would have done”,现在相反“would+原形”： 混合虚拟分主从，各自时态看时间： 从句过去“had done”,主句现在“would+动原”； wish后接虚拟时，过去用“could have done”: 真实陈述用直陈，虚拟真实要区分： It's high time特殊记，后面动词用过去。 真题演练 演练一：单项选择试题（共10题） 1.If Iyou,I accept the invitation immediately.
