08-语法专题突破16讲(八) 情态动词与虚拟语气.ppt

解析：此题考查虚拟语气。在虚拟条件句中，如果表达与过去事实不符的情况，if从句的谓语应使用“had＋过去分词”的结构。故选D项。 答案：D 虚拟条件句 主句 例句 与现在事实相反的假设 If ＋主语＋动词的过去式(be 动词通常用were) 主语＋should/would/could/might＋动词原形 If I had time，I would go to the concert. If I were you，I should seize the chance. 与过去事实相反的假设 If ＋主语＋had ＋过去分词 主语＋should/would/could/might＋have＋过去分词 If I had practised more，I would have passed the driving exam. 虚拟条件句 主句 例句 与将来事实相反的假设 ①If ＋主语＋动词过去式②If ＋主语＋were to ＋动词原形③If ＋主语＋should ＋动词原形 主语＋should/would/could/might＋动词原形 If you came tomorrow，we would have the meeting. If it were to rain tomorrow，the sports meeting would be put off. If he should not come tomorrow，we should put off the meeting till next Monday. [注意]　(1)混合条件句 主句与从句的动作发生在不同的时间，这时主、从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。 If it had rained last night，it would be very cold today. 如果昨天晚上下了雨，今天就会非常冷。 (2)虚拟条件句的倒装 虚拟条件句的从句部分如果含有were，should或had，可将if 省略，再把were，should或had 移到从句句首，实行倒装。 Should it rain，the crops would be saved.＝Were it to rain，the crops would be saved. 要是下了雨，庄稼就会有救了。 (2011·安徽师大附中模拟)But for the fact that China ________also affected by the global economic crisis，we________fewer unemployed workers now. A．is；would have　　　　 B．were；would have C．was；would have had D．were；would have had 解析：句意：如果中国没有受到全球性经济危机的影响，现在我们就会有更少的失业者。第一空表示现在的事实，用一般现在时；第二空表示与现在相反的虚拟语气，用would/should/could/might＋动词原形。 答案：A 有时假设的情况并不以条件从句表示出来，而是隐含在某些词或短语中，如otherwise, without (没有)，but for(要不是)等。 Without electricity，there would not be modern industry. 要是没有电的话，就不会有现代工业了。 But for the leadership of the Party，we could not live such a happy life.要不是党的领导，我们就不会生活得这么幸福。 (2010·福建高考)Teachers recommend parents ________ their children under 12 to ride bicycles to school for safety. A．not allow B．do not allow C．mustnt allow D．couldnt allow 解析：考查虚拟语气。recommend后跟宾语从句应用虚拟语气，其结构为“should＋动词原形”，should 可以省略，故A正确。 答案：A 1．虚拟语气用于名词性从句中 (1)虚拟语气用于主语从句中 ①在句型“It is /was ＋过去分词＋that 从句”中，当过去分词为insisted，required，demanded，decided，proposed，urged，requested，suggested，recommended，ordered 等时，从句中要用“should ＋动词原形”(should 可
