虚拟语气要点解读复习知识点精析精练 一、if条件句中的虚拟语气 虚拟条件句 虚拟情况 主句 从句 与现在事实相反 主语＋should/would/could/might＋do if＋主语＋过去式(be用were) 与过去事实相反 主语＋should/would/could/might＋have done if＋主语＋had＋过去分词 与将来事实可能相反 主语＋should/would/could/might＋do if＋主语＋过去式/were to do/should＋do If the new safety system had been put to use，the accident would never have happened. 要是新的安全系统被投入使用的话，这起事故就不会发生了。 We would be back in the hotel now if you didn't lose the map. 如果你没有把地图弄丢的话，我们现在就回到旅馆了。 Grace doesn't want to move to New York because she thinks if she were to live there，she wouldn't be able to see her parents very often. 格蕾丝不想搬到纽约，因为她认为如果住在那里，她就不能经常看到她的父母了。
初二下册英语电子课本 1．如果在表示虚拟语气的if从句中含有were，had或should，可将if省略，然后将were，had或should移至主语之前。 2．如果主句和从句是对不同时间的事实的虚拟，则被称为错综虚拟语气。此时主句常有明显的时间状语。 二、含蓄条件句的虚拟语气 有时假设的条件不通过条件状语从句表达出来，而是隐含在某些词或短语中，或隐含在上下文中，这叫含蓄虚拟语气。常用的这类词或短语有：without(要是)没有；but for要不是；otherwise/or否则等。 —Do you have Betty's phone number? ——你有贝蒂的电话号码吗？ —Yes.Otherwise，I wouldn't have been able to reach her yesterday. ——有。不然我昨天就联系不上她了。 Many of the things we now benefit from would not be around but for Thomas Edison. 要不是托马斯·爱迪生，我们现在从中受益的很多东西就不会存在。 Ⅰ.单句语法填空 1．(2020·浙江台州模拟考试)It's a pity that you were late, otherwise you would have seen(see) the star from Korea. 2．I should not have laughed if I had thought(think) you were serious. 3．(2020·西安九校联考)Don't handle the vase as if it were(be) made of steel. 4．(2020·湖北武昌区高三调考)If we hadn't made(make) adequate preparations，the conference wouldn't have been so successful. Ⅱ.单句改错 5．(2020·湖北武汉高三调考)If it were not to rain tomorrow, the crops will not be saved. will→would It was suggested yesterday that a meeting ________ to discuss the matter. A. will be held B. would be held C. should hold D. be held The look on his face suggested that he ________ quite satisfied with what I had done for him. A. will be B. being C. should be D. was 答案： D；D 详解：It is/was suggested（据建议）后接的that从句应用虚拟语气，谓语动词要用should+动词原形，should可以省略，所以可排除A、B；从句的主语与谓语之间是被动关系，空格处应填(should) be held。 详解：suggest当“表明”讲时，其后的that从句应用陈述语气。从句的动作与主句的动作同时发生，所以从句的谓语动词应用一般过去时。
