虚拟语气 (1) 动词的语气表示说话人的态度和看法，可分为陈述语气、祈使语气和虚拟语气。陈述语气用来陈述讲话人认为是事实的事情，有肯定、否定、疑问和感叹等形式。祈使语气用来说明说话人的请求、命令等。虚拟语气表示说话人的愿望、假设或建议，而不表示客观存在的事实。虚拟语气通过谓语动词的特殊形式来表示。 如果假设的情况发生的可能性不大，则用虚拟条件句。虚拟条件句分为三种，见下表： 假设情况 条件从句的谓语形式 主句的谓语形式 与现在事实相反 过去式 (be 的过去式 常用 were) would /should/ might/ could ＋动词原形 与将来事实相反 过去式 should ＋动词原形 were to ＋动词原形 would /should/ might/ could ＋动词原形 与过去事实相反 过去完成式 (had ＋过去分词 ) would /should/ might/ could ＋ have ＋过去分词 If I had time ， I would attend the meeting. 如果我有时间，我就参加会议了。 ( 与现在事实相反 ) If I were you, I should seize the chance to go abroad. 如果我是你，我会抓住这个出国的机会。 ( 与现在事实相反 ) If you had taken my advice, you would not have failed in the exams. 如果你采纳了我的建议，你就不会通不过考试了。 ( 与过去事实相反 ) If you came tomorrow, we would have the meeting. 如果你明天来，我们将召开会议。 ( 与将来事实相反 ) If it were to rain, we should get wet. 要是下雨的话，我们就会淋湿了。 ( 与将来事实相反 ) If he should not come tomorrow, we should put off the meeting till next Monday. 如果明天他不来，我们就要把会议推到下周一。 ( 与将来事实相反 ) 【 单项填空 】 ①Sorry, I didn ’ t finish my work. If I________ enough time, I________it. A ． had; would finish B ． have; could have finished C ． had had; would have finished D ． have had; have finished ②He is not native; if he were; we ________this discussion over his identity. 　　　　　　　　　　　　　　　　　　 A ． would not be having B ． are not having C ． had not had D ． will not have 答案　 ① C 　 [ 由前句可知后句应使用虚拟语气，表示与过去情况相反。 if 引导的非真实条件句中的谓语动词形式为： had ＋动词 ed 形式；主句谓语动词的形式为： would/ should /might/ could have ＋动词 ed 形式。 ] ②A 　 [ 考查虚拟语气的用法。句意：他不是本国人，如果他是的话，我们就不会在讨论他的身份问题了。根据 were 可知，此处为与现在事实相反的虚拟语气，而只有 A 项是虚拟语气主句的结构。 ] 【 单项填空 】 ________strict with me when I was young ， I could not be such a successful person now. A. If you are not B ． If you were not C ． Were you not D ． If you had not been 答案　 D 　 [ 考查错综虚拟语气。句意：如果在我年幼时你没有对我严格要求的话，我现在就不可能是这么成功的一个人。根据句意可知，此题中主句说的是与现在事实相反的情况，而从句说的是与过去事实相反的情况，所以从句要用过去完成时，故选 D ，如果采用省略句，其结构应该是 had you not been 。 ] 【 单项填空 】 ①________ today, he would get there by Friday. But he won ’ t set off when it is raining. A ． Would he leave B ． Was he leaving C ． Were he to leave D ． If he leaves ②________ listened to the doctor, you ________ all right now. A ． If you; are B ． If you; were C ． You had; would be D ． Had you; would be 答案　 ① C 　 [ 由语境可知非真实条件从句表示将来不可能实现的事情，故从句谓语动词的形式为：过去式 (be 用 were)/ should ＋动词原形 /were to ＋动词原形，如果省略 if ，要将从句中的 were ， should ， had 等提到句首。 ] ②D 　 [ 根据主句中的时间状语 now ，可知表示与现在情况相反，故主句中谓语动词的形式为 would ＋动词原形。依据语境可知条件句表示与过去情况相反，故条件句中谓语动词的形式为 had ＋动词的 ed 形式，省略 if 时，要将 had 提到句首。 ] (3) 通过上下文的含义，句中往往有 but ， otherwise 等。 I was very busy yesterday, otherwise I would have helped you. 我昨天很忙，不然的话，我会帮助你的。 She would have said no. But that she was afraid. 要不是她害怕的话，她就会说 “ 不 ” 了。 If only I had more money, I could buy the apartment. 要是我有更多的钱，我就会买这套公寓了。 But for your advice, I could not have done it so successfully. 如果不是听了你的建议，我就不会做得如此成功。 The change could not have taken place without the open door policy. 没有开放的政策，就不会有如此大的变化。 【 单项填空 】 ①Without water in the world, everything ________.

A ． hadn ’ t finished B ． didn ’ t finish C ． couldn ’ t have finished D ． couldn ’ t finish 答案　 ① B 　 [without 短语表示非真实条件，故句子使用虚拟语气。因其表示与现在事实相反，谓语动词的形式应为： would ＋动词原形。 ] ②C 　 [ 根据 Thanks a lot. 可知 without your help 表示非真实条件，故后句中应使用虚拟语气，由语境可知句子表示与过去情况相反，故谓语动词的形式应为： would/ should /might/ could have ＋动词 ed 形式。 ] 议论文 【 写作任务 】 假如你是本地报社的一名记者，要对昨天新华中学的学生就 “ 是否允许医学克隆存在？ ” 展开的辩论进行报道，下表是双方理由和辩论结果，请据此写一篇新闻稿。 【 写作内容 】 正方理由 反方理由 辩论结果 1. 医学克隆将会给那些因重病而丧失行动和思考能力的人带来福音； 2. 医学克隆的操作程序对病人来说将会是万无一失、安全和快捷的； 3.67% 的美国民众支持医学克隆。 1. 克隆仍然存在着安全隐患； 2. 生成医用或研究用的胚胎需要反复的尝试，在这一过程中很多潜在的生命会被无情扼杀。 反方说服力稍逊，最终观众投票正方获胜。 3 ．根据题目要求对辩论情况进行客观报道，准确把握要点。准确运用高级词汇并注意新闻类体裁的语言特点。适当运用复杂结构以提高文章的表述层次。注意篇章的整体处理和语言的连贯，并力求条理清晰、层次分明。 第二步：提炼要点 1 ． medical cloning 2 ． support the motion 3 ． serious illnesses 4 ． procedures would be safe 5 ． convincing 6 ． to oppose medical cloning 7 ． potential lives 8 ． a lively discussion 第三步：扩点成句 1 ． The arguments for medical cloning were very strongly put by the team supporting the motion. 2 ． They argued that people who were losing their ability to move or think because of serious illnesses could be helped by medical cloning. 3 ． They explained that the procedures would be safe, quick and with no problems for the patients. 4 ． Their arguments were very convincing. 5 ． The arguments put by the team opposing medical cloning were less strong.
