‎2019届二轮复习语法专题虚拟语气 虚拟语气 ‎1．虚拟语气用于条件状语从句中 ‎(1)虚拟语气在非真实条件句中的运用 类别 从句谓语动词 主句谓语动词 与现在事实相反 过去式(be用were)‎ should/would/could/might＋动词原形 与过去事实相反 had＋过去分词 should/would/could/might＋have＋过去分词 与将来事实相反 过去式(be用were)‎ should/would/could/might＋动词原形 should＋动词原形 were to＋动词原形 If my brother were here, everything would be all right.‎ 要是我哥哥在这儿的话，一切都没问题了。‎ If it should rain this afternoon, the basketball match would be put off.‎ 要是今天下午下雨，篮球比赛就会被推迟。‎ If you had taken my advice, you would not have failed in the exams.‎ 如果你早听了我的建议，你考试就能通过了。‎ ‎(2)虚拟条件句中的省略与倒装 如果虚拟条件句中含有were/had/should，有时可把if省略，把were/had/should提到主语之前形成倒装；若为否定形式，not不可提前。‎ Had he caught the morning train, he would not have been late for the meeting.‎ 要是他赶上了早晨的火车，那他就不会开会迟到了。‎ ‎(3)错综时间条件句 有时条件句的动作与主句动作发生的时间不一致，这时动词的形式应根据它们各自表示的时间加以调整。‎ If we had booked a table earlier, we wouldn't be standing here in a queue.‎ 如果我们早些订位子，现在也就不用站在这里排队了。(if条件句是对过去的虚拟，而主句是对现在的虚拟。)‎ ‎(4)含蓄条件句 ‎①有时假设的情况不用条件句表达，而是用but for, without等介词(短语)或上下文来表示。‎ We wouldn't have finished the project on time without your timely help.‎ 如果没有你的及时帮助，我们就不能按时完成那项工程了。‎ ‎②用连词otherwise, or等暗示后文与前面的情况相反，从而引出后文的虚拟语气。‎ I was ill that day. Otherwise, I would have taken part in the sports meeting.‎ 我那天病了，否则，我就参加运动会了。‎ ‎③虚拟条件通过but暗示出来，模式为“虚拟情况＋but＋真实情况”。‎ I would have delivered a speech, but I had a cold that day.‎ 我本来可以做演讲，但是那天我感冒了。‎ ‎2．虚拟语气用于名词性从句中 ‎(1)在“It is＋important/necessary/natural/strange/essential/vital/a pity＋that ... ”句型中，that从句中谓语动词用“(should＋)动词原形”。‎ It's vital that we (should) take our safety driving along the road seriously.‎ 认真对待我们在路上开车时的安全非常重要。‎ ‎(2)在would rather (that)后的宾语从句中，从句的谓语动词如果表示现在或将来要发生的动作，从句用一般过去时；如果表示过去发生的动作，从句用过去完成时。‎ I'd rather he had gone to the seaside with me the day before yesterday.‎ 要是他前天和我去海边就好了。‎ ‎(3)句中含有以下单词或变形时，该句中的名词性从句(宾语从句、表语从句、主语从句、同位语从句)部分常用虚拟语气，其谓语动词形式为“should＋动词原形”，其中should可以省略。‎ He suggested that we (should) start off early the next day.‎ 他建议我们第二天早点出发。‎ ‎[名师指津]　当suggest表示“暗示，表明”之意，insist表示“坚持说”之意时，suggest/insist后的宾语从句不使用虚拟语气，而使用陈述语气。‎ The smile on his face suggested that he was satisfied with our work.‎ 他脸上的微笑表明他对我们的工作很满意。‎ The man insisted that he had never stolen the money.‎ 那个人坚持说他从没有偷过那笔钱。‎ ‎(4)wish后宾语从句中的虚拟语气 虚拟语气 从句谓语动词 与现在事实相反 过去式(be动词一般用were)‎ 与过去事实相反 had＋过去分词 与将来事实相反 would/could＋动词原形 I wish (that) I were ten years younger.‎ 但愿我能年轻十岁。‎ I wish (that) I had met that film star yesterday.‎ 我多希望昨天见到了那个影星。‎ ‎(5)as if/though引导的表语从句和方式状语从句中的虚拟语气 as if/though引导的从句中的谓语动词形式及使用情况与wish后宾语从句中的谓语动词及使用情况相同。‎ She looks as if nothing had happened to her.‎ 她看起来好像什么事都没有发生似的。‎ ‎[名师指津]　如果从句中描述的事情可能会发生，那么从句中的谓语动词可 用陈述语气。‎ It sounds as if it is raining.‎ 听起来像是在下雨。‎ ‎3．2个特定句式中的虚拟语气 句型结构 过去虚拟 现在虚拟 将来虚拟 if only引导的条件句及感叹句 had＋过去分词 过去式(be动词一般用were)‎ would/could/should/might＋动词原形 It is (high/about/very) time (that) ...‎ 过去式或“should＋动词原形”‎ If only I had seen the film.‎ 要是我看过那部电影就好了。‎ It is high time that we should start/started out.‎ 我们该出发了。‎ ‎[命题点感悟]　　考什么·考多少·怎么考 ‎ 单句语法填空/单句改错 ‎①(2017·北京高考改编)If the new safety system________(put) to use, the accident would never have happened.‎ 解析：had been put　句意：如果新的安全系统被投入使用，这次事故就不会发生了。由句意和主句中的谓语动词形式可知，此句是对发生在过去的事情的假设，条件状语从句中应该使用过去完成时。‎ ‎②(2016·全国卷Ⅱ)Some classmates suggest we can go to places of interest nearby. ‎ 解析：去掉can或can→should　suggest表示“建议”时，后面的宾语从句的谓语动词要用“should ＋动词原形”，should可以省略，故答案有两种改法。‎ ‎③(2015·四川高考)If you are me, would you talk to them?‎ 解析：are→were　根据语境可知，此处是虚拟语气，表示与现在情况相反，所以要把are改为were。‎ ‎[专题过关训练] ‎ ‎[题点全面练]‎ Ⅰ.用适当的情态动词填空 ‎1．When I was a child, I could watch TV whenever I wanted to.‎ ‎2．—What are you doing this Saturday?‎ ‎—I'm not sure, but I might go to the Rolling Stones concert.‎ ‎3．The door won't (not) open, no matter how hard she pushed.‎ ‎4．One of our rules is that every student shall wear school uniform while at school. ‎ ‎5．—Shall I inform him of the change of the schedule right now? ‎ ‎—I am afraid you must,_in case he comes late for the meeting.‎ ‎6．We needn't (not) have bought so much food now that Suzie won't be with us for dinner.‎ ‎7．—Who can be phoning us at this time of night? ‎ ‎—It might be your sister.‎ ‎8．We can't imagine that two children should be killed by the washing machine of their house.‎ Ⅱ.用所给动词的正确形式填空 ‎1．The national smog serves as a constant reminder, indicating that it's high time we reflected (reflect) on ourselves.‎ ‎2．—It would_be (be) cool if I won this contest.
