高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。
虚拟语气复习专练 学习目标：旨在协助学生复习虚拟语气，为阅读和写作打下基础。 考查要点： 1. 考查if 非真实条件从句中的虚拟语气 3. 考查suggest ,advise, insist表示建议、要求动词从句中动词用should虚拟语气 4. 考查if only…要是…就好了 5. It is (high) time that句型中，动词用did或should do 【注意】1.suggest表示暗示、表明时,不用虚拟语气,用陈述语气。 The smile on her face suggested that she was satisfied with our work. 2.当insist表示“坚持认为，坚持说”之意时, 不用虚拟语气,用陈述语气. 表示“坚持要求，坚持主张”用虚拟语气。如：The man insisted that he had never stolen the money 3.only if表示"只有" I wake up only if the alarm clock rings.只有闹钟响了，我才会醒。 【写作赏析】 1.How I wish I could have apologized to him yesterday! 2.If I were the headmaster, I would choose those excellent students. 3.If it had not been for his help (= without/but for his help), we would not have succeeded. 4.My English teacher suggested that I should read more to improve my English. 5.It’s high time that something was done about the traffic problem. 6.If only I were a college student now in Beijing! 【小结】虚拟语气用来表达说话人的意愿、请求、设想等未能或不肯能实现的事实，或说话人看来实现的可能性很小的情况。英语水平较高的学生能够用它能够成为一种写作的“制胜秘技”，为自己的写作增添一道亮丽的风景线。 虚拟语气练习 一、单项选择 1.

2020年高考英语写作新题型备考技巧 专题（八）强调倒装虚拟句型+丰富文章细节的手段 特殊句型是英语书面表达中的高级句式，其中强调句和倒装句是较为常见的特殊句型。而虚拟语气也是高中较难掌握的句型之一。它们的准确使用能够彰显考生的英语水平，提高写作档次。 一．重点突出的强调句型 （一）强调句的基本句式结构为：It is/was + 被强调部分+ that/who + 句子其他成分。它可以强调除谓语动词外的其它任何成分，如主语、宾语、状语等。在续写和概写中灵活运用强调句不仅能突出重点、增强表达，更能彰显考生的英语运用能力。 It is just the so-called inconvenience that displays the richness, delicacy and great fascination of Chinese culture with a history of thousands of years. (2019年浙江高考书面表达) 在写作中运用强调句型可以采取以下步骤： 1.在一个写好的句子中找出需要强调的成分，如主语、宾语、状语等； 2.根据句子的时态确定is或was； 3.然后把要强调的成分套进句式里，It is/was + 被强调部分+ that/who + 句子其他成分。 例：We created a harmonious atmosphere with sincerity and faithfulness. 如果我们要强调状语，即with sincerity and faithfulness，在确定好时态was后，把需要强调的部分放在it was后，that后放除强调外的剩余成分便得到： It was with sincerity and faithfulness that we created a harmonious atmosphere. （二）强调句常用句式 1. It is/was + 被强调的部分+ that/who + 句子其它成分 It is on the playground this Friday afternoon that a volleyball game will be held. (2019全国一卷书面 表达) It was because of their help that a disaster was avoided. (2017年浙江高考书面表达) 2. Is/was it + 被强调的部分+ that/who + 句子其它成分 Was it in the park that the children saw the strange green objects? 3.特殊疑问词+ is/was it + 被强调的部分+ 句子其它成分 When was it that you made up your mind to work as a volunteer teacher? 4.It is/was not until that + 句子其它成分

Eg 2. 如果没有审查制度，信息高速公路可能会变成电子“红灯区” If there were no information censorship, the information highway would be in danger of becoming an electronic “red light district”。 2. 虚拟过去时是表示与过去事实相反的假设， if从句的谓语形式用过去完成时，即had+ 过去分词，主句用would/should/could/might+have+过去分词。Eg. 1 如果发达国家过去没有捐赠不计其数的救援物资，发展中国家成百上千的穷人就会死于饥饿或传染病。 If developed countries had not donated countless relief materials, millions of poor peo ple in developing countries would have died of hunger or infectious diseases. Eg. 2. 如果中国没有审查网络，那么青少年就会接触到不雅的材料, 例如暴力与色情 If China had not censored the internet, minors could have been exposed to indecent materials such as violence and pornography. 3. 虚拟将来时是表示对将来事实可能相反的假设。 if从句的谓语形式用一般过去式或用were to/should + 动词原形，主句用would/should/could/might + 动词原形 Eg 1. 如果吸食毒品合法化，警察大量的时间就将用于解决更严重的问题 If drug use were to be legalised, considerable police time could be spent in dealing with other more serious problems. Eg 2. 如果西方国家停止资助第三世界国家，第三世界国家会寻求经济独立。If western countries should stop financing the Third World, it would struggle for its ec onomic independence. 4. 省略if采用倒装语序的条件句 有时可以吧含有助动词、情态动词、be或have的虚拟条件句中的连词if省去，而将had,should,were等词提到主语之前，即用倒装结构。**如果没有 had,should,were等词，既不能省略if, 也不能倒装。

Neanderthals had developed muscles in their stomach To argue against the readings assertion that these muscles helped Neanderthals to speak, the lecturer argues that these muscles could have been used for other purposes. Instead, she states that perhaps the muscles helped them to travel farther or climb mountains easier. 在讲座中，教授对于尼安德特人是否会说话这一争论给出了自己的见解，阅读中的观点是讲他们腹肌非常发达，所以可以帮助他们说话;而教授却指出他们的这些肌肉可能是用来生存，而非帮助他们讲话的，因为当时他们生存的环境比较严酷，因此需要这些发达的腹部肌肉来爬山或远足。但是听力中教授在谈到这个观点时的语气也是一种猜测的口吻，所以我们在写这个段落的时候就可以使用虚拟语气。上面划线的这个句子里由于主语在后面的意思中是一个"被动"的意义，所以作者在虚拟语气后采用了被动语态。也许这样说有些考生还是无法完全体会虚拟语气的"强大"之处，因此我们不妨把这个地方改成常规的句子比较一下就可以看出明显的差别："...these muscles had been used for...", 改了之后的过去完成时表示的是他们"肯定已经用了腹肌"，这样一来意思完全和教授在讲座中的意思不一样了，所以表达就不够准确。想要获得高分的考生在这个细节上一定要特别注意。 The next point brought up is that deforestation by the Dutch destroyed the dodos natural habitats. However, the professor first claims that deforestation did not cover the entire island nor did it kill many other bird species. He next declares that dodos did

虚拟语气（上） 一、虚拟条件句 一般来讲，英语中的虚拟语气分为两大体系：一是表示与事实相反的或假想的情形，通常由if引导，叫做“非真实条件句”，或者叫 “虚拟条件句”；另一个体系是在名词从句中使用虚拟语气，表示建 议、命令或要求等语气，这是一个完全不同于非真实条件句的虚拟的 结构形式。虚拟语气的重点和难点都集中在虚拟条件句中。 1.虚拟条件句的“两时三类” 虚拟条件句分为“两类三时”，两种类型有：假设条件句和事实相反句。三时：即是对将来、现在和过去这三种时间的虚拟。假设条 件句一般用在将来或现在可能性不大的情形，而过去已是事实，故不 使用此情形。事实相反句一般用作现在或过去，表达与事实相违背的 情形，而将来还未发生，故不适应于此情形。 2.虚拟条件句的谓语变化必背 虚拟的时间主句的谓语形式（Z）IF从句的谓语形式（C）将来(j)Zj：would(could,might)+do Cj：were to do/should do 现在(x)Zx：would(could,might)+do Cx：did或were 过去(g)Zg：would(could,might)+have done Cg：had done或had been 为了方便，表中Z表示主句，C表示从句，j表示将来，x表示现在，g表示过去。
以上6种不同的谓语形式，必须分别记住，因为在实际的使用中，主从句的谓语可能会出现混合虚拟的情况。所以，在写作或口语交际中，需要四步走：1.判断是否虚拟；2.何时虚拟；3.主句虚拟；4.从句虚拟。以上四步，一步都不能少，否则就会出错。 二、将来虚拟（ZjCj）考点 结构：从句用were to do或should do，主句用would do。 将来虚拟只能是用来谈将来的“不太可能”的情形，其在很大程度上是由说话人对事件的态度决定的。 If I were to live my life over again,I would have you as my wife. 如果我有来生，我一定会娶你为妻。 再来比较下列真实条件和将来虚拟条件的区别： 1）If it were to rain,I would stay home. 2）If it rains,I will stay home. 这两个例句中不同语气的选择，反映了说话人对未来下雨的可能性的信心程度不同。在例1）中，用了虚拟语气，表明说话人认为将来不太可能会下雨。在例2）中，用了陈述语气，表明说话人认为将来下雨的可能性比较大。
