Unit4 语法学案虚拟语气
虚拟语气语气是指讲话人对说话内容的看法：包括陈述语气，祈使语气和虚拟语气。
虚拟语气是表示对说话的内容的怀疑，推测，假设，想象或祝愿，而不是当作客观事实。
一、非真实条件句虚拟条件句可以分为三种：一类是叙述与现在事实相反的情况；一类是叙述与过去事实相【注意】1. 主句中的should ，could ，might 具有情态意义。
2. 与将来事实相反是，条件句中谓语可由“should+动词原形”构成，但要注意这里的should不能被would ，could ，might 等替代。
3. 从句中单数be 动词一般用 ，但是口语中有时可以用was 。
二、省略if 的条件句当虚拟条件句中的谓语动词是 、 、 时，可以将其提到句首，省略if 。
eg. Had I been told earlier, I could have done something. Were she here, she would do something. Should it rain, I would stay at home._____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 三、错综条件句在错综条件句中，主句的时间和从句的时间不一致， 因此主句和从句的谓语动词要根据各自的时间选择适当的虚拟语气形式。
（从句与过去事实相反，主句与现在事实相反。
）’(从句this morning 说明过去，主句now 说明现在) 四、含蓄条件句在句子的表面没有if 等表示条件的句子，但句子的深层含义中或上下文中隐含着虚拟条件句。
常用的词 、 、 、 、 等。
对比下面句子：eg. But for your help, we couldn ’t have succeeded. Without you, we couldn ’t have finished the task. He must be at home, or his car wouldn't be here.If it had not been for the captain, the ship would have sunk.We were delayed at the airport; otherwise we would have been here by lunch time.【注意】 suppose, supposing 用作连接词，意思是imagine what will/would happen if…。

It’s high time that you went. 你该走了。 It’s high time that you should go. 我们该去 It’s time that we went to bed.
睡觉了。
It’s time that we should go to bed.
4.表示要求，命令，建议的虚拟语气。 1.宾语从句。常见动词： 一个坚持，两个命 令，三个建议，四个要求。即 1.insist 2. order, command

I wish I were as tall as you.

高中英语必修四unite4知识点
高中英语必修四unite4知识点高中英语必修四Unit 4主要讲述了语法和词汇两个方面，是英语学习的重点内容。
以下将分别进行介绍。
一、语法知识点1.虚拟语气虚拟语气在英语中是比较重要的一个语法知识点，尤其在口语和写作中经常使用。
它表示的是虚假的或非真实的情况，根据它在句子中的位置不同，可以分为主语从句、宾语从句和条件句。
主语从句：主语从句中，虚拟语气的形式是“should/were + 动词原形”，表示的是我们想象的或未实现的条件，如“如果我有一百万美元，我就会去环游世界。
”宾语从句：宾语从句中的虚拟语气也是“should/were + 动词原形”，但是要注意的是在有些情况下（如宾语从句为动词不定式时）没有虚拟语气。
条件句：条件句中的虚拟语气分为三种情况：第一类条件句表示与现实相反的假设，其形式为“if+过去式+would/could/should+动词原形”，如“If I had enough money, I would buy a house.”；第二类条件句表示与现实相反的假设，其形式为“if+过去完成式+would/could/should+动词原形”，如“If I had met him last week, I could have helped him.”；第三类条件句表示可能发生的情况，其形式为“if+现在式+will/can/should+动词原形”，如“If I have time tomorrow, I will help you.”2.被动语态被动语态在英语中也是一项基本的语法知识点，其句子的主语是被动的，动作的执行者则成为状语，主语可以是各种词类，而被动语态的形成则是将动词的过去分词加上助动词“be”。
被动语态的应用：在写作中被动语态可以强调动作的执行者或结果，可以包含更多的信息，比如说，科技论文中常常应用被动语态来描述实验的程序和结果。
二、词汇知识点1.词根、前缀和后缀词根、前缀和后缀对于学习英语单词是非常有帮助的，在语音、语法和意义的理解方面都有很大的作用。

九年级英语Unit4虚拟语气的用法
九年级英语Unit4虚拟语气的用法虚拟语气是一种动词形式,表示说话人的愿望、假设、猜测、建议等含义，虚拟语气所表示的含义不是客观存在的事实。
下面重点谈谈虚拟语气在条件句中的用法，虚拟语气条件句是用谓语动词的特殊形式来表示与现在、过去事实相反的情况或对将来发生的情况表示怀疑。
具体情况如下：1. 表示与现在事实相反的情况例如:If I were you , I'd get there earlier.如果我是你,我就早一点到那儿。
（事实是：我不是你，因此我没有早到那儿。
）If you went to bed earlier, you would not be so sleepy in the morning. 如果你早点儿睡觉, 早晨就不会这么困了。
（事实是：你经常晚睡, 所以早上觉得困。
）去事实相反的情况例如: If you had worked hard, you wouldn't have failed the exam . 如果你早用功, 你就不至于考试不及格了。
（事实是:你早没用功,所以考试失败了）.表示与将来事实相反的情况例如: If it rained tomorrow, our picnic would be put off.如果明天下雨,我们的野餐就推迟。
(事实是:最近天气很好,下雨的可能性不大)If you should be late tomorrow, we would not wait for you.万一你明天迟到了, 我们就不等你了。
（事实是: 迟到是意料之外的事情注意。
）注意：用虚拟语气表示条件的条件从句, 可以放在主句前,也可以放在主句后, 但所表达的意义侧重点不同。
主句在前时，强调“结果”；从句在前时，强调“条件”。
巩固练习：一、单选题( ).１. If I were you ,I try my best.A. wouldB. shallC. hadD. will( ) 2. If I ten years younger, I very happy.A. am ; shall beB. were ; would beC. were ; shall beD. am ; would be( )3.If I to the moon, I would bring something unusual back to the earth.A. goB. goesC. wentD. will go( ) 4. If Jane here now , she would explain to us how to do it.A. beB. isC. wasD. were( ) 5. “You can ask your brother for help.” “He is not at home. If he , I .”A. is ; wouldB. is ; willC. were ; wouldD. were ; will二、用动词的正确形式填空6. If I ( be ) a teacher , I would not be so strict with my students.7. If he ( have ) time, I would come to help you .8. If she were not so busy , she ( come ) here with me .9. He ( go ) to bed if he had finished doing his homework in time .10. If it ( rain ) tomorrow , our picnic would be put off .答案：1．A 2. B 3. C 4. D 5. C 6. were 7. had 8. would come 9. would have gone 10. rained 解析：1—8 都表示与现在事实相反的情况，条件从句的谓语动词用动词的过去式（ be 一般用were ），主句的谓语动词用would 或 should + 动词原形。
九年级unit4虚拟语气知识点

新目标九年Unit4语法
Unit4语法本单元语法重点（Grammar Focus）虚拟语气1. 语气就是我们常说的说话人说话的口气。
在汉语中，语气是由说话人说话的语调、情节等等表现出来的，动词没有任何变化。
而在英语中，除了语调之外，最主要的是动词发生变化而表示不同的语气。
在英语中语气分为三类：陈述语气、祈使语气、虚拟语气。
2. 虚拟语气：如果我们所说的不是事实，也不是要求、命令、劝告等，而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气。
3. 虚拟语气常用在条件句中，及其他一些从句中。
注意：条件句分两种，真实条件句和虚拟条件句。
只有在虚拟（非真实）条件句中，才用虚拟语气，而在真实条件句中，要用陈述语气。
请比较：（1）If it is sunny tomorrow, we’ll go to the zoo. 如果明天天气好，我们将会去公园。
在这句话中，明天天气好是完全有可能实现的，并非虚拟、幻想，因此是真实条件句。
在本句中，适用“主将从现。
”（2）If I were you, I would go at once. 如果我是你的话，我立刻就走。
在这句话中，条件句，“如果我是你”，但事实上，我不可能成为你，这只是假设的情况，没有实现的可能。
当条件实现的可能性很小，甚至可以说没有时，就需要用虚拟语气来表示，动词发生了变化。
4. 在虚拟语气中，句子动词的时态比真实条件句中的时态后退一步即：现在时→过去时（该用现在时时，用过去时）过去时→过去完成时（该用过去时时，用过去完成时）将来时→过去将来时（该用将来时时，用过去将来时）过去将来时→过去将来完成时（该用过去将来时时，用过去将来完成时）在这一单元中，我们只要求初步接触虚拟语气的用法及结构，学习表示与现在事实相反的情况下如何体现虚拟语气。
5. “表示与现在事实相反的情况”的虚拟语气请看例句：If I were you, I would take a small present. 如果我是你的话，我就带上一个小礼物。

Unit Four 虚拟语气 语法精讲
Unit Four 虚拟语气语法精讲一，虚拟语气的定义：虚拟语气表示说话人认为所说的话是和事实相反的内容，只是一种愿望、假设、猜测、建议、或空想，用于条件句或某些动词之后，在这样的句子中要用虚拟语气。
二，虚拟语气在条件从句中的用法及动词形式。
表示与现在事实相反的情况：从句：If + 主语+ 动词的过去时，（be 动词一律用were ）, 主句：主语+ would + 动词原形。
三，区别if 引导的三种从句。
A, if 引导的条件状语从句：主句：主语+ will + 动词原形。
从句：if + 从句（用一般现在时）。
即，主将从现。
B，if 引导的虚拟语气：从句：If + 主语+ 动词的过去时，（be 动词一律用were ）, 主句：主语+ would + 动词原形。
C, if 引导的宾语从句：若主句为一般现在时，从句可以根据事实情况选用如何时态。
若主句为一般过去时，从句必须要用过去的某种时态。
