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．。
4、通过Were it not for...或Had it not been for...等句式表达条件
Were it not for(=If it were not for) the leadership of the Party,we could not live a happy life.
Given more attention, the trees could have grown better.
与现在事实相反过去时（were）
与过去事实相反had+过去分词
与将来事实相反would/could/might+动词原形
I wish I were as tall as you.
He wished he hadn't said that.
I wish it would rain tomorrow.
三．表示要求,命令,建议的虚拟语气
一个（坚持） ___insist______
两个（命令） ___order, command_________
三个（建议） ___suggest, advise, propose_(recommend)__
四个（要求） __require, demand, request, __ask________
这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词使用should + 动词原形, 或者将should省略。The doctor suggested that he (should) try to lose his weight.
He insisted that we (should) tell him the news.
It is arranged that he leave for Canada on Friday.
What do you think of his proposal that we should put on a play at the English evening
My suggestion is that we should go there at once.
四．It’s necessary/strange/natural/ important/pity/no wonder/impossible + that Clause 从句中的动词要用虚拟, 即(should)+动词原形
I It is a great pity that you (should) think so.
It is highly desirable that a new president be appointed for this college．
It is strange that the girl（should）be so arrogant．
五. would rather 后的宾语从句,用虚拟语气
I would rather you could teach me again.
The manager would rather that his secretary went to the meeting instead of him .
六. as if， as though引导的从句, 用虚拟语气
以as if 、as though（似乎，仿佛）引出的方式状语从，如果表示真实情况应该用直陈语气；如果表示非真实情况，都必须用虚拟语气。当从句表示与现在的事实相反，谓语动词用一般过去时；表示与过去事实相反要用"had ＋过去分词"；表示与将来可能相反的则用"would（could，might）＋动词原形"。
The little boy knows so many things as if he were an adult
He acted as usual as though nothing had happened.
七. 由if only （要是……，那该多好啊！）引导的惊叹句,用虚拟语气
If only I had passed the test ！
If only it stopped raining！
If only I had taken mother's advice
比较if only与only if
only if表示“只有"；if only则表示"如果……就好了"。If only也可用于陈述语气。
I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。
If only the alarm clock had rung. 当时闹钟响了，就好了。
If only he comes early. 但愿他早点回来。
八. It is (high) time that
It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。
It is time that the children went to bed.
It is high time that the children should go to bed.
It is high time that we had our lunch. 该是我们吃午饭的时候了。
It is time that he made up his mind. 该是他作出决定的时候了。
九、在和idea，necessity，plan， motion，order，proposal，recommendation，suggestion，under- standing 等词有关的同位语或表语从句中，谓语动词用动词原形或"should ＋动词原形"表示虚拟语气。
My idea is that the group（should）hold another session to discuss the problem．
Emphasis is laid on the necessity that all the objectives to be attained be taken into account before starting a new project．
十、虚拟语气用在简单句中，表示祝愿，命令。
May you be happy. 祝你幸福。
May you have a good time. 祝愿你玩的痛快
十一、情态动词中的虚拟语气
didn't need to do表示：过去不必做某事, 事实上也没做。.
needn't have done表示：过去不必做某事, 但事实上做了。
John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽，所以她不必步行回家了。
John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽，所以她本不必步行回家了。 (Mary步行回家，没有遇上John的车。)

（1）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类： (1) 从属连词that。如： The trouble is that I have lost his address. 麻烦是我把他的地址丢了。 (2) 从属连词whether, as, as if。如： He looked just as he had looked ten years before. 他看起来还与十年前一样。 The question is whether they will be able to help us. 问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago, but it's as if it was only yesterday. gh能跟表语从句的谓语动词一般为系动词be, seem, look等。如： It looked as if it was going to rain. 看起来天要下雨了。 连接副词 where, when, how, why。 如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 The question is how he did it. 问题是他是如何做此事的。 That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 解释： 1．连词because可引导表语从句。如： I think it is because you are doing too much. 我想这是因为你做得太多。 2．在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。（2）主语从句 1．定义：用作主语的从句叫做主语从句。 2．构成：关联词+简单句 3．引导主语从句的关联词有三类： (1) 从属连词that。如：That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。 (2) 从属连词whether。如： Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。 (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词 where, when, how, why。如： What she did is not yet known. 她干了什么尚不清楚。 How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。 Whoever comes is welcome. 不论谁来都欢迎。 Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。 解释： 1．主语从句能用it作形式上的主语。常以it作形式主语的句型有： A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 It is probable that he told her everything. 很可能他把一切都告诉她了。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that
按：本套资料省去了名词、代词、形容词等部分，保留了最最核心的句型和动词。希望能有所帮助。 第一章名词性从句 在句子中起名词作用的句子叫名词性从句。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It作形式主语和it引导强调句的比较 It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 - b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …; It is an honor that…; It is common knowledge that… (2) It is ＋形容词＋从句 It is natural that…It is strange that… . (3) It is ＋不及物动词＋从句 It seems that…It happened that…It appears that… (4) It ＋过去分词＋从句 It is reported that…It has been proved that…It is said that… 3. 主语从句不可位于句首的五种情况： （1）if引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. ( 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not. 错误表达：Whether he is wrong or not doesn’t matter. （5）含主语从句的复合句是疑问句时，主语从句不可提前。例如： ； 正确表达：Is it likely that it will rain in the evening 错误表达：Is that will rain in the evening likely 4. what 与that 在引导主语从句时的区别 what 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：

英语的句子成分主要有六种：即主语、谓语、宾语、定语、状语和补语。（可以熟记为：主谓宾，定状补）除了这六种主要成分之外，还有“表语”和“同位语”的说法。但表语和系动词一起作谓语，因此划分成分时，划分在谓语上。同位语分为主语同位语和宾语同位语，属于主语或宾语的一部分。 考点1. 划分句子成分时的常用符号 英语中划分句子成分的符号 主语在下面画直线 谓语在下面画曲线 宾语在下面画双横线 定语在下面画虚线?（一行点使我们想到一排钉子，“钉”谐音为“定语”的“定”）状语下面为短横线（短横线使我们想到短木桩，木桩撞（状）钟） 补语上一短横，下一短横（下一短横好像是为了弥补上面短横间的空隙） 同位语上下双曲线（都有曲折，上下位置基本相同） 考点1. 主语 主语是一个句子所叙述的主体，一般位于句首，通常由名词性的词来充当。 可以作主语的词性或语法结构： 1. 名词 2. 代词 3. 数词 4. 不定式 5. 动名词 6. 主语从句等表示。 7. 名词化的形容词（如the rich） 在英语中，形容词、副词和介词短语是不能作主语的。如果它们在句首时，句子可能是倒装句，真正的主语在后面。 On the desk are some books. (主语是books，所以用are) Down jumps the boy. (主语是the boy，所以用jumps ) Gone are the days. (主语是the days，所以用are) 练习1. 在下面句子的主语下面画横线，并说出由什么充当。 1.During the 1990s, American country music has become more and more popular. 2.We often speak English in class. 3.One-third of the students in this class are girls. 4.To swim in the river is a great pleasure. 5.Smoking does harm to the health. 6.The rich should help the poor. 7.When we are going to have English test has not been decided. 8.It is necessary to master a foreign language. 9.That he isn’t at home is not true. 10.There comes the bus. 11.Beyond the village lies a small village. 12.Now comes your turn.

英语的句子成分主要有六种：即主语、谓语、宾语、定语、状语和补语。（可以熟记为：主谓宾，定状补）除了这六种主要成分之外，还有“表语”和“同位语”的说法。但表语和系动词一起作谓语，因此划分成分时，划分在谓语上。同位语分为主语同位语和宾语同位语，属于主语或宾语的一部分。 考点1.划分句子成分时的常用符号 英语中划分句子成分的符号 主语在下面画直线 谓语在下面画曲线 宾语在下面画双横线 定语在下面画虚线（一行点使我们想到一排钉子，“钉”谐音为“定语”的“定”） 状语下面为短横线（短横线使我们想到短木桩，木桩撞（状）钟） 补语上一短横，下一短横（下一短横好像是为了弥补上面短横间的空隙） 同位语上下双曲线（都有曲折，上下位置基本相同） 考点1.主语 主语是一个句子所叙述的主体，一般位于句首，通常由名词性的词来充当。 可以作主语的词性或语法结构： 1. 名词 2. 代词 3. 数词 4. 不定式 5. 动名词 6. 主语从句等表示。 7. 名词化的形容词（如the rich） 在英语中，形容词、副词和介词短语是不能作主语的。如果它们在句首时，句子可能是倒装句，真正的主语在后面。 On the desk are some books. (主语是books，所以用are) Down jumps the boy. (主语是the boy，所以用jumps ) Gone are the days. (主语是the days，所以用are) 练习1.在下面句子的主语下面画横线，并说出由什么充当。 1.During the 1990s, American country music has become more and more popular. 2.We often speak English in class. 3.One-third of the students in this class are girls. 4.To swim in the river is a great pleasure. 5.Smoking does harm to the health.
高中英语语法大全之形容词和副词 形容词及其用法 形容词修饰名词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面。 1)直接说明事物的性质或特征的形容词是性质形容词，它有级的变化，可以用程度副词修饰，在句中可作定语、表语和补语。例如：hot 热的。 2)叙述形容词只能作表语，所以又称为表语形容词。这类形容词没有级的变化，也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如：afraid 害怕的。 （错）He is an ill man. （对）The man is ill. （错）She is an afraid girl. （对）The girl is afraid. 这类词还有：well，unwell，ill，faint，afraid，alike，alive，alone，asleep，awake 等。 3）形容词作定语修饰名词时，要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时，要放在这些词之后，例如： something nice 以-ly结尾的形容词 1）大部分形容词加-ly可构成副词。但friendly，deadly，lovely，lonely，likely，lively，ugly，brotherly，仍为形容词。 改错：(错）She sang lovely. （错）He spoke to me very friendly. （对）Her singing was lovely. （对）He spoke to me in a very friendly way. 2）有些以-ly 结尾既为形容词，也为副词。 daily，weekly，monthly，yearly，early The Times is a daily paper. The Times is published daily. 用形容词表示类别和整体 1）某些形容词加上定冠词可以泛指一类人，与谓语动词的复数连接。如：the dead，the living，the rich，the poor，the blind，the hungry The poor are losing hope. 2）有关国家和民族的形容词加上定冠词指这个民族的整体，与动词的复数连用。 the British，the English，the French，the Chinese. The English have wonderful sense of humor. 多个形容词修饰名词的顺序 多个形容词修饰名词时，其顺序为： 限定词--数词--描绘词--(大小，长短，形状，新旧，颜色) --出处--材料性质，类别--名词 a small round table a tall gray building

高考英语语法知识之It 的用法总结 1．It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，状语。强调的主语如果是人，that可以由who换用。 如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3．It is clear ( obvious, true, possible,certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ... 该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ... 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen . That was the worst song that he had heard . 11. It is .... since ...
