专四虚拟语气题目及讲解概要1.ppt

虚拟语气 回顾历年真题 虚拟语气讲解 1、It’s getting late. I’d rather you __now.A、leftB、leaveC、are leavingD、will leave Would rather后面接从句时，表示主语宁愿某人做某事，从句用虚拟语气，动词用一般过去式，表示希望。注意区分would rather 其它两个惯用句式：would rather do sth. “宁愿做某事”；would rather do…than do…“宁愿做某事而不愿做某事” 2.It is necessary that he __ the assignment without delayA. hand in B. hands in C. must hand in D. has to hand in 考查的是虚拟语气。“It + be +a. +that ”从句，that引导的主语从句谓语动词常用should +动词原形。用于该句型的形容词有necessary, good, important， right， wrong, better, natural, proper, funny, strange, surprising等。 3、If there were no subjunctive mood ,English__ much easier to learn.A、could have seen B、would be C、will beD、would have been 本体表示与现在事实相反的假设。表示与现在事实相反，条件从句用一般过去式，主句使用should (would) + 动词原形。A项 could have been 是对过去事实的假设、与从句所表示的现在事实不符合；C项 wil 不用于虚拟语气中；D项是与过去事实相反的假设的虚拟语气从句形式。 4.Had Judy been more careful on the maths exam , she __ much better results now.A. Would be getting B. could have got C. must get D. Would get 条件句与过去事实相反，虽然主句的时间副词为now，但事实上该成绩已经出来，故用could have got. 而不是 would get. 5. If only the patient__ a different treatment instead of using the antibiotics, he might still be alive now. A. had receivedB. received C. should receiveD. were receiving if only 常常用来表达强烈的愿望或遗憾，主要用在虚拟语气中。由于所提事实与过去事实相反，所以用过去完成时。 6. If only I __ play the guitar as well as you!A. wouldB. couldC. should D. might 考察虚拟语气中情态动词的用法。If only从意义和语法上都相当于I wish，后面的谓语动词用一般过去时表示目前的愿望，用过去完成时表示过去的愿望，用would/could do 表示将来的期望。A项侧重人的意愿，B项指人的能力。 7. It’s high time we __ cutting down the rainforests. A. stoppedB. had to stopC. shall stopD. stop It’s (high) time (that) 后面的从句谓语动词用一般过去式或should +动词原形，且should 不可省略。 8.__ you __ further problems with your printer, contact your dealer for advice. A. If ,had B. Have ,hadC. Should ,have D. in case ,had 本句表示对现在和将来情况的虚拟：Should you have further problems 其实是从 If you should have further problems 转化而来的哦，通常这类从句后面，主句的谓语用祈使语气或陈述语气。 In case“万一，以防”，后面
