人教版高考英语一轮复习语法专题11情态动词和虚拟语气课件.pptVIP

4.含蓄条件句 有时候假设的情况不以if引导的条件句形式表现出来, 而是通过介词短语、连词或其他形式表示。常用的单词或短语有: without, with, but for, otherwise, or, but等。 Without his wartime experiences, Hemingway wouldn’t have written his famous novel A Farewell to Arms. 如果没有战时的经历, 海明威就不会写出他的著名小说《永别了, 武器》。 But for your advice, I could not have done it so successfully. 要是没有你的建议, 我就不会这么成功。 I was so busy then; otherwise, I would have gone to help him. 那时我太忙了, 否则我就去帮他了。 They were abroad during the months when we were carrying out the investigation, or they would have come to our help. 我们开展这项调查的几个月期间他们在国外, 否则他们会来帮助我们的。 5.错综时间条件句中的虚拟语气 当条件状语从句表示的行为和主句表示的行为发生的时间不一致时, 这种句子就是 “错综时间条件句”, 动词的形式要根据主句和从句所表示的时间做出相应的调整。 If we had booked a table earlier, we wouldn’t be standing here in a queue. 如果我们早点儿预订一张桌子, 我们就不用站在这儿排队了。(从句说的是过去的情况, 主句说的是现在的情况) 6.省略if的虚拟语气 如果if从句中含有were/should/had时, 则可以省略if, 把这三个词置于句首, 采用倒装语序。 If I were you, I would go to the party. →Were I you, I would go to the party. 如果我是你, 我会去参加聚会。 If it should happen, what would you do? →Should it happen, what would you do? 如果那件事真的发生了, 你会做什么? If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你早点来的话, 你就赶上那辆公交车了。 考点二 wish后的宾语从句中的虚拟语气用法 在wish后的宾语从句中, 表示与现在或过去的事实相反, 或对将来的主观愿望, 通常用虚拟语气。从句中谓语动词的形式有以下几种: 1.表示对现在情况的虚拟, 从句中的谓语动词用过去式(be动词用were)。 —Do you like the school? —Yeah. I only wish the classes were a little smaller. ——你喜欢这个学校吗? ——是的。我只希望班级小一些。 2.表示对过去情况的虚拟, 从句中的谓语动词用 “had+过去分词”。 I wish I had been at my sister’s wedding last Tuesday, but I was on a business trip in New York then. 我真希望自己上个星期二能参加姐姐的婚礼, 可是我当时正在纽约出差。 3.表示对将来的主观愿望, 从句中谓语动词常用“would/could/might+动词原形”。 I wish it would be fine tomorrow. 我希望明天有个好天气。 考点三 谓语动词必须用 “(should+) 动词原形” 的情况 1.表示 “建议, 要求, 命令”的动词: 一坚持(insist), 二命令(order, command), 三建议(suggest, recommend, advise), 四要求(demand, require, request, ask)后面的宾语从句或由it做形式主语的主语从句中的谓语动词要用 “(should+) 动词原形”。这些动词相应的名词后的表语从句和同位语从句中的谓语动词也要用“(should+) 动词原形”。 The teacher ordered that the homework (should) be handed in on time. 老
