2014高考英语(北师大版)总复习课件语法专项突破六名词性从句和虚拟语气.ppt

19. (2013·赣州模拟)— Yesterday， I didn’t see Ben at the party. — You ________ him. We just came back from Beijing this morning.  A. mustn’t have seen B. needn’t have seen C. couldn’t see D. can’t have seen 答案 D 解析 考查情态动词。由于我和本今天早晨才从北京回来，所以你昨天“不可能”在聚会上见到本的。 20. (2013·昆明模拟)But for the heavy traffic， the police _________ the thieves who tried to escape in the stolen car.  A. would not catch B. couldn’t have caught C. haven’t caught D. couldn’t catch 答案 B 解析 考查虚拟语气。but for the heavy traffic相当于without the heavy traffic / if it hadn’t been for the heavy traffic。如果不是交通拥挤的话，警察就抓不住小偷了。根据who tried可知此处表示与过去事实相反。 21. (2013·哈尔滨模拟)— I paid him 300 yuan for the sneakers.  — Oh， he charged you too much. You ________ them with half the money.  A. could have bought B. needn’t have bought C. must have bought D. wouldn’t have bought 答案 A 解析 考查虚拟语气。答语句意：他向你收的钱太多了。你本来可以以半价买到的。could have done“过去本能够做某事却没有做到”。 22. (2013·合肥模拟)They didn’t turn up at the meeting yesterday. Otherwise， they ________ the report.  A. had listened to B. would listen to C. should listen to D. would have listened to 答案 D 解析 考查虚拟语气。“他们昨天没有出席会议”这是事实，暗示的虚拟条件是“if they had turned up at the meeting yesterday”，所以D项正确。 23. (2013·温州模拟)Look at the trouble I am in. If only I ________ your advice then.  A. followed B. would follow C. had followed D. should follow 答案 C 解析 考查虚拟语气。根据then(那时)可知此处表示的是与过去事实相反的情况，故if only后的从句用过去完成时。 24. (2013·西安模拟)— This is the first time I ________ my first picture with my own hands.  — It’s time that you ________ a photo of me.  A. took； took B. have taken； took C. took； will take D. will take； have taken 答案 B 解析 考查虚拟语气。this is the first time后的从句中应用现在完成时，这是固定用法。第二句it’s time后的从句谓语动词用“should+动词原形”或动词过去式。 25. (2013·杭州模拟)________ about his financial situation， I would have helped him out.  A. Did I know B. Had I been knowing C. Had I known D. Have I known 答案 C 解析 考查虚拟语气。根据主句谓语would have helped ...可知此句是表示与过去事实相反的虚拟语气，故从句谓语用过去完成时。C项相当于If I had known。 26. (
