虚拟语气的表达法？

Question

谁能帮我看看我写的虚拟语气的表达法哪里有写不对，为什么怎么都通不过，其实我对英语是不懂啦，但是老师要我写“虚拟语气解析”并给了我提纲，我就根据他的提纲在网上找的这些资料拼凑的，但是总也通不过，她就是说不对，谁能帮我修改修改呢？谢谢啦！！！

1. 时间倒退法
1）现在时间的假设（对现在情况的虚拟，与现在的事实相反）：
从句用过去式或过去进行式(时间上是同时的)。其句子结构为：宾语从句的谓语be和were(was)，实义动词用过去式。例：
1. I wish (that可省略,下同)I knew the answer to the question.(wish, 动词过去式knew)我希望知道这个答案。(事实上是不知道)
2. I wish it were spring in my hometown all the year around.(wish, were)但愿我的家乡四季如春。(事实上不可能)
3. I wish I were a bird.(wish, were)但愿我是只小鸟。(事实上不可能)
4. When she was at the party,she wished she were at home.(wished,过去虚拟动词were)(事实上并不在家)
5. Now that he is in China, he wishes he understood Chinese.(wishes,过去虚拟动词understood)
现在他在中国，他希望能懂得中文。(事实上并不懂)
6. When we begin the trip, they will wish they were with us.(will wish,过去虚拟动词were)(事实上并不和我们在一起)
2) 过去时间的假设（对过去情况的虚拟，和过去的事实相反）：
用wish表示对过去事情的遗憾。其句子结构为：宾语从句的谓语用过去完成时，或would, could, might+现在完成时。例：
1. I wish (that可省略，下同)I hadn't wasted so much time.
我后悔不该浪费这么多时间。(事实上已浪费了)
2. He wishes he hadn't lost the chance.
他真希望没有失去机会。(其实已失去)
3. We wished he had spoken to us.
(wished，had + spoken)(事实上他并没同我们讲)
4. I wish you had called earlier.
(wish, had + called)(事实上已迟了)
5. They will wish they had listened to us sooner.
(will wish,had + listened)(事实上并不如此)
动词wish后面接从句，表达不可能实现或与事实相反的情况时，谓语动词要用虚拟语气，即用过去式（表示现在发生的动作）或过去完成式（表示过去发生的动作）。本题后半句谓语动词have用的是过去时had
to get up and come, 所以前面要用过去完成时表示过去发生的动作。所以, 选项A)could have slept是答案
3) 将来时间的假设（对将来情况的虚拟，表示将来的主观愿望)：
从句动词"would/should/could/might + 动词原形"(时间上较后)(请注意：主句和从句的主语不相同)。用wish表示对将来事情的愿望。例：
1. I wish it would stop raining.(虚拟动词would+动词原形stop)
我希望雨能停止。(事实上雨还在下着呢)
2. I wish you would be quiet.(would + be)
我希望你安静一些。(事实上那家伙还在吵着呢)
3. You wished she would arrive the next day.(would + arrive)
你希望她第二天会到。(事实上她还没到)
4. I wish she would change her mind.(would + change)
我希望她会改变主意。(呵呵，女孩子可没那么容易就改变主意喔)
5. He will wish we would join him the following week.(would + join)
(只是希望我们和他在一起，实际上还没在一起)
注意：1.如果将wish改为过去式wished, 其后that 从句中的动词形式不变。例如：
I wished I hadn't spent so much money.
我要是那时没有花掉那么多钱就好了。
2. 如果that 从句中用would , 一般表示对现状不满或希望未来有所改变或请求

Answer 1

虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一.虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测.
Ⅰ用以表示虚拟条件的虚拟语气
⒈ 用if条件从句表示的虚拟条件,是虚拟条件最普通的方式.
① 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might +动词原形,例如：If I were in your position I would marry her.
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,例如：If it had not rained so hard yesterday we could have played tennis.
③ 大多数的虚拟条件句属于上面三种情况的一种,但并不排除存在条件和后果中,一个和现在情况相反,另一个和过去情况相反,例如：If you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高.
④ 但是,如果后果用了虚拟语气,而条件却用陈述语气,这种用法是错的.
⒉ 除了表示虚假条件外,if从句还可以表示对将来的推测,由于是将来还没有发生的,所以谈不上是真实的还是虚假的,只能说这个事情发生的可能性有多大.一般情况下,可以用陈述语气的if从句来表示对一个未来事实的推测,这个事实是完全可能发生的.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,例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.（1996年1月四级第44题）
⒊ 有时可以把含有助动词、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,这时候,如果出现not等否定词,否定词需放在主语后面.这种结构在口语中很少使用,但频频出现在各类考试中出现,例如：If it had not rained so hard yesterday we could have played tennis.→Had it not rained so hard yesterday, we could have played tennis.
⒋ 大多数的虚拟条件通过上面所讲的两种方法表达,但在个别句子中也可以通过介词without和介词短语but for表达,副词otherwise等表达出来.例如：We didn't know his telephone number; otherwise we would have telephoned him.（1995年6月四级第46题）值得注意的是,包含but for的句子,谓语动词必定要用虚拟形式,但包含without等短语的句子,谓语动词未必一定要用虚拟语气.
⒌ 有时虚拟条件不是明确地表达出来,而在蕴含在用but引导的从句里,于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句,例如I would have hung you but the telephone was out of order.在这样的句子里,如果主句没有用虚拟语气,或者从句用了虚拟语气,都是错的.
Ⅱ用在宾语从句中的虚拟语气
⒈ 在表示愿望的动词wish后的宾语从句中,需用虚拟语气.（wish后的that 常省略）,根据主句时态,从句谓语时态相应退后一位,例如：How she wished his family could go with him.
⒉ 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气.谓语动词用(should) +动词原形.值得注意的是,如果宾语从句的动词是否定的,否定词not的位置应在动词之前,而不是动词之后.例如：The head nurse insisted that the patient not be move.另外,如suggest表达“暗示”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气,例如：Her pale face suggests that she is ill.或He insisted that he did not kill the boy.
除此之外,上述动词也要求用虚拟式
① 在It is+上述动词的过去分词,其后所跟的主语从句中,如It is suggested that pupils wear school uniforms.
② 在上述动词相应的名词形式作主语+连系动词,其后的表语从句中,例如His suggestion was that classed be re-scheduled.
③ 在对上述动词相应的名词进行解释的同位语从句中,如：The workers raised the demand that their pay be increased to cope with the inflation.
⒊ would （had）rather , would sooner也用来表达主观愿望,它们之后的宾语从句中需用虚拟语气.谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反,例如：I would rather he went right now.
Ⅲ其他形式的虚拟语气
⒈ it is +necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等,例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly.
⒉ 在It's (high/about) time 之后的定语从句中需用虚拟语气.谓语动词用过去式,例如It is high time that you went to school
⒊ 虚拟语气在as if / as though 引导的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式.例如：He felt as if he alone were responsible for what had happened. 表示过去想象中的动作或情况,谓语动词用过去完成式.
⒋ 在lest 引导的状语从句中,谓语动词多用虚拟语气,(should )+ 动词原形.例如： The mad man was put in the soft-padded cell lest he injure himself.（1998年1月四级第38题）
⒌ 在if only 引起的感叹句中需用虚拟语气.谓语动词用过去式或过去完成式.例如： Look at the terrible situation I am in! if only I had followed your advice.

老师为什么要你写，直接告诉你正确的不就好了吗，还浪费你的时间。
是不是因为你的只有关于WISH的用法呢？
——————————————————————————————
虚拟语气在非真实条件状语从句中的用法
1、真实条件状语从句与非真实条件状语从句
eg .
If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴士。( 真实条件状语)（不是虚拟语气）
If he was free, he would ask me to tell stories. 如果他是空闲的，他会要求我讲故事。（真实条件状语）（不是虚拟语气）
If I were you, I would go at once.如果我是你，我马上就会去。 （非真实条件状语从句）
If there were no air, people would die. 如果没有空气，人就会死亡。（非真实条件状语从句）
2、虚拟语气在非真实条件状语从句中的用法及动词形式
① 表示与现在事实相反的情况：
主语+should/would/could/might+do+其他
if+主语+did/be(were)+其他
例：
1.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）
2.If I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。（事实：不知道）
3.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)
4.If I had any money with me, I could lend you some. 如果我带钱了，我就会借给你些。（事实：没带钱）
5.If he studied harder, he might pass the exam.如果他再努力些，就能通过考试了。（事实：学习不用功）
②表示与过去事实相反的情况
主语+should/would/could/might+have done+其他+
if+主语+had done +其他
例：
1. If I had got there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。（事实：去晚了）
2.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表示对将来情况的主观推测（可能相反或可能性很小）
主语+should/would/could/might+do+其他
if+主语+did/should/were to do+其他
例：
1.If he should come here tomorrow, I should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。 （事实：来的可能性很小）
2.If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。（事实：不知能否下雪）
3.If she were to be there next Monday, I would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事的始末。
在表示建议、命令、要求等含义的宾语从句，谓语动词常用虚拟语气，"should＋动词原形"构成，should 可省略。

虚拟语气的其他用法
①、虚拟语气用在wish 后的宾语从句
a、表示与现在事实相反的愿望，谓语动词用过去式
eg. I wish I had your brains.我希望我有你那样的头脑。(事实：我根本比不上你)
b、表示过去事实相反的愿望，谓语动词：had+v-ed
eg:.I wish I had known the truth of the matter.我希望我原来知道这件事的真相。（事实：原来不知道）
c、表示将来难以实现的愿望
谓语动词：should/would + 动词原形
eg. I wish I should have a chance again.我希望我还能有一次这样的机会。（事实：很难再有这样的机会了）
(注：if only和even if也有相同用法）
②虚拟语气用在 一想要(desire)一宁愿(prefer)二命令(order. command) 三建议(advise. suggest. propose) 五要求(demand. require. request. desire.insist)中，无论主句谓语动词为何种时态，从句的谓语动词都用：“should + 动词原形”或只用“动词原形”。
如 He suggested that we (should) take the teacher’s advice
He insisted that we (should) take the teacher’s advice
He demand that we (should) take the teacher’s advice
He ordered that we (should) take the teacher’s advice
注：insist如果翻译成坚持某种动作才用虚拟语气翻译成坚持某种观点就不用虚拟语气。
如：He insist he is a student. 他坚持说他是个学生。
这个语句表示的是事实，因此在这个语句中不能使用虚拟语气。
suggest意为“建议”才用虚拟语气，意为“暗示”则不用虚拟语气。
如： His face suggests that he looks worried .他的表情暗含着他很担心。
这个句子本身是事实，因此它就没有用到虚拟语气。
③表情绪.观点的形容词或名词也要用虚拟语气.如:necessary. important. impossible. natural. strange. surprising.
funny. right. wrong. better. a pity等。
句型：It is.......that 结构后的主语从句，从句的谓语动词都要用 should+原型 或只用动词原型。
④虚拟语气在方式状语从句的应用。详百度百科之方式状语从句词条。

就上面所说的方式状语从句：

定义
方式状语从句常见的引导词有表示“像……”的as和表示“好像……”的as if/as though， 例如： Let’s study as Lei Feng studied. 让我们像雷锋那样学习吧。// Think as I think. 像我这样去想。// He talks as if/though he is drunk.从他谈话的样子来看他好像醉了。
1. 方式状语从句通常由as, (just) as…so…, as if, as though引导。
1） as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：
Always do to the others as you would be done by.
你希望人家怎样待你，你就要怎样待人。
As water is to fish, so air is to man.
我们离不开空气，犹如鱼儿离不开水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。
2） as if, as though
两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如：
They completely ignore these facts as if (as though) they never existed.
他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。）
He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。）
It looks as if the weather may pick up very soon.
看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。）
说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如：
He stared at me as if seeing me for the first time.
他目不转睛地看着我，就像第一次看见我似的。
He cleared his throat as if to say something.
他清了清嗓子，像要说什么似的。
The waves dashed on the rocks as if in anger.
波涛冲击着岩石，好像很愤怒。
2.其他的引导词
1）the way：Please pronounce the word the way I do.请照我这样,读这个单词.
2）口语常用的like：He sit there smiling like it was his birthday.他面带微笑坐在那儿,像是过生日似的. （这里用了虚拟语气，值得注意的是be动词用的was，而表示虚拟as if引导的be动词则只能是were。）

例题解析
〔考题1〕 When a pencil is partly in a glass of water, it looks as if it ____. (1995)
A. breaks B. has broken
C. were broken D. had been broken
〔答案〕 C
〔解析〕 当说话者认为句子所述的是真实情况或者是极有可能发生、 存在的情况时， as if/though引导的方式状语从句需用陈述语气形式。 但表示所叙述的情况与事实相反时as if从句中应使用虚拟语气。注意比较以下两个例句：
He walks as if he is drunk.
He walks as if he were drunk.
前一句表示“他已经醉了”， 后一句则表示“他没有醉”。
〔考题2〕 Eliza remembers everything exactly as if it ____ yesterday. (2006)
A. was happening B. happens
C. has happened D. happened
〔答案〕 D
〔解析〕 as if后的谓语动词应采用一般过去时的形式与状语yesterday搭配， 表示对现在真实情况的虚拟。本回答被提问者采纳
