高中英语虚拟语气详细讲解 虚拟语气 什么是虚拟语气？是的，我们要学习虚拟语气就必须先弄明白它的概念。 虚拟语气包含两种：一种指与事实相反或不可能发生。“虚拟条件句+虚拟主句”的结构都属于这一类；even if、even though、as if、as though引导的状语中如果需要用到虚拟语气也属于这一类；wish、would rather后面接的宾语从句表示不可能实现的愿望，还是属于这一类。 另一种指与事实实际是否发生没有直接关系。如和suggest、order、demand等表示建议、命令、要求等相关的名词性从句都属于这一类。 大家知道以上两类虚拟语气后，我们就从从句的角度来系统学习虚拟语气。紧跟小简老师的步伐哦！ 一. 虚拟条件句中的虚拟语气 1、表示与现在事实相反的情况 从句：If+主语+did(be动词用were) 主句：主语+ should/would/might/could+do
If I were you,I would take an umbrella. 如果我是你，我会带把伞。（事实：我不可能是你） If I knew his telephone number,I would tell you. 如果我知道他的，我就会告诉你。（事实：不知道） If there were no air or water,there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) 2、表示与过去事实相反的情况 从句：If+主语+had+done 主句：主语+should/would/might/could+have done If I had got there earlier,I should/would have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话） 3、表示与将来事实相反的情况

高中英语虚拟语气知识 点及练习 内部编号：（YUUT-TBBY-MMUT-URRUY-UOOY-DBUYI-0128）
虚拟语气：虚拟证据表示说的话不是事实，或者不可能发生的情况，而是一种愿望、建议或者与事实相反的假设等，一般常用于正式的书面语中。 一、虚拟语气在if条件从句中的用法： 1、a. If I were you, I would apply for the job. b. If I lived near my office, I would walk to the office. 与现在事实相反，If条件从句谓语：过去式（be用were） 主句谓语：should / would / could / might+动词原形 2、a. If you had been more careful, You could have passed the exam. b. If you had turned off the gas, the house wouldn’t have caught fire. 与过去事实相反，If条件从句谓语：had+动词过去分词 主句谓语：should / would / could / might + have done 3、a. If it should rain tomorrow, we would not go camping. b. if it were to rain tomorrow, we would not go camping. c. If it rained tomorrow, we would not go camping. 与将来事实相反：If条件从句谓语：过去式 / should + v原形 / were + to do 主句谓语：should / would / could / might + do 二、混合虚拟条件句：不同时间的虚拟，各遵守各的规则，如： a. If you had followed the doctor’s advice, you would be quite all right now. 从句叙述与过去事实相反（had + done），主句叙述与现在事实相反（would + v）
【The Subjunctive Mood】 语气 (mood)是一种动词形式，用以表示说话者的意图或态度。英语中的语气有三种：陈述语气、祈使语气和虚拟语气。 陈述语气(indicative mood),表示所说的话是事实。 祈使语气 (imperative mood),表示所说的话是请求或命令。 虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或及事实相反的假设等。 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句及非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句及结果主句都用陈述语气。 如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句及结果主句皆须用虚拟语气。
1. 及现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式 (be的过去式用were), 主句的谓语用should （would, might, could）+动词原形。 如： If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。 （事实是：天在下雨，我们不能出去野餐。表示愿望。） If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。 （事实是：他没来这，他不可能帮助你。表示对他的良好印象。） 2. 及过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （ would, might， could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited. 要是当初她被邀请的话，她就会去参加这次聚会了。 （事实是：当时没有人邀请她，因此，她没有来参加聚会。表示后悔。） If she hadn't called me, I would have overslept this morning. 今天早上，她要是不叫我的话，我就会睡过头了。 （事实是：她今天早上叫我了，我没有睡过头。表示感激。）
Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) 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1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。
高中虚拟语气精讲 英语动词有三种语气，陈述语气，祈使语气和虚拟语气。 定义：用来表示说的话不是事实，或者是不可能发生的情况，而是一种 愿望，建议，假设的语气叫虚拟语气。 ●虚拟语气在条件状语从句中的用法。 假如我有足够的钱, 我就去环游世界. If I had enough money, I would travel around the world. 假如我是你, 我就不会说那样的话. If I were you, I would not say that. 假如我听了你的建议, 我就不会犯错误了. If I had taken your advice, I wouldn’t have made a mistake. 假如明天下雪的话, 我就不去野营了. If it should rain tomorrow, I wouldn’t go camping. ●有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个 主句或者一个条件从句。 ●假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致， 叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间 而定。(“各归各”的原则） If the weather had been finer, the crops would be growing still better. If you had followed the teacher’s advice, you wouldn’t fail the exam now. ●假设条件虚拟倒装。条件从句中有should，were，had三个助动 词可以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If it were not for your advice, we couldn’t have got over the difficulties. Were it not for your advice, we couldn’t have got over the difficulties. If I had had time, I would have run round that lake again. Had I had time, I would have run round that lake again. If there should be a flood, what should we do?

With favorable winds, we might have arrived there in two days. ●with, or, otherwise, but, however 引导的从句如与事实不符，用虚拟 My parents lent me the money. Otherwise, I couldn't have afforded the trip.我父母借钱给我了。否则，我可付不起这次旅费。（虚拟） Shut the window, otherwise it'll get too cold in here. （非虚拟） I'm lucky that I'm interested in school work, otherwise I'd go mad.
高三年级安全工作计划 篇一：高三年级工作计划 东台市安丰中学 XX-XX学年度高三年级组工作计划 为进一步提高我校高三年级的教学效益，增强各项工作的针对性，力争XX年高考取得成功，学校在总结前几届高三复习经验的基础上，针对本届学生实际，特制定高三管理方案： 一、情况介绍 本届高三共有17个教学班，其中物化组合5个班，物生组合7个班，政史组合2个班，史地组合3个班，在班学生885人（其中借复读生164人），应届生721人，加上在东中借读的10人左右，总人数比上一届要少70人左右，这一届学生由于在三仓中学后一批次录取，生源与仓中相差不大，优质生源还略差于三仓中学，中考时全东台前1000名、1500名、XX名，我校分别比仓中少12人、44人、7人；与前几届相比，生源下降明显；加上本届在高一阶段时正值四星级高中验收，学校组织开展了多项活动，造成主要学科课时不足，学生的基础不够扎实，学生的行为习惯养成也没有完全到位，因而高一高二阶段整体的优势不够明显，小高考成绩也未能全面反超三仓中学。尽管在9月份的盐城市高三摸底考试中我校达本二模拟线的465人，比仓中多60人左
右，各个分数段人数均高于三仓中学，但部分学科的均分、达B率仍低于三仓中学，这一成绩与社会、家长、上级的要求相比形势仍然是严峻的，压力是相当大的。本届高三聘用教师69人，语文12人，数学15人，英语12人， 6门选科用27人，体育3人。 二、指导思想 以“一切为了学生的美好未来”为宗旨，以“班之为战、科之为战、有效教研、全面超越”为策略，深化课堂教学改革、扎实推进有效教学，科学管理、合理调控、优化配置、加强督导与考核，使学生成人成才，创XX年高考佳绩。 三、管理队伍 学校校长、党总支书记卢惠斌老师亲自督查协调高三年级，并建立由副校长、主任、年级组长参加的高三年级管理小组，由分管教学的副校长顾劲松老师担任年级分管校长，教务处副主任贾新荣老师担任年级分管主任，年级分为两个部，一部部长为办公室副主任任益老师，副部长为教科室副主任姜波老师；二部部长为贾新荣兼任， 副部长为政教处副主任朱世权老师。省优秀班主任、高三15班班主任王如玉老师担任年级组长。高三17位班主任中有省、县级优秀班主任5人，老中青结合，有9人是原高三留任的。 四、年级目标

虚拟语气在非真实条件句中
①错综时间条件句: 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为错综时间条件句，动词的形式要根据它表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。如：If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars) 如果你有100万元，你会做什么？ We couldn?t have finished the work ahead of time without your help. (=if we
