虚拟语气的倒装以及错综虚拟语气 1. 注意四个情态动词的用法 （1）若表示在某一假设的条件下，必然而然就会发生某事，第一人称可用should或would, 而二、三人称只用would. （2）若表示在某一假设条件下就能够干某事，各人称都用could. （3）如果表示在某种假设条件下有可能会发生某事，各人称都用might. 2. 虚拟语气的倒装 当虚拟条件句中含有 were，had，should，could等动词时，可以将if省略，然后将 were，had，should， could 等词移至句首。  注意：以上移至句首的 had不一定是助动词，如果是实义动词也可倒装： If he had money，he would buy a car. Had he money，he would buy a car. 3. 错综虚拟语气（主从句指的是不同的时间，根据上下文的意思采用不同的谓语动词形式） 高中英语单词表3500词必背 英语单词记忆法 人教版初中英语单词 常见的两种错综虚拟语气： （1）从句与过去事实相反相成，而主句与现在事实相反。例如：    If you had not been strict with me when I was young, I could not be such a successful person now.（这种虚拟语气的特点是主句中常含有时间准状语now 或nowadays） （2）Should anyone come and ask for me, tell them I will come back tomorrow.（主句为祈使句，条件句与将来事实相反，表示说话人认为某件事情发生的可能性很小。） 题1： Tom took the police to the spot ______ the accident happened． A. which          B. that          C. where      D. when 题1： C  详解：______ the accident happened是定语从句，其先行词是spot。从句缺少地点状语，所以选where。 题2： Our partnership with France Telecom is really a win-win situation ______ both sides benefit a great deal.
