1、虚拟语气总结be型和were型虚拟语气总结：be型和were型目录： 学习虚拟语气的三个必知一、were式虚拟 二、be式虚拟 三、几个特殊的句式学习虚拟语气必须明确了解以下三点：1、英语的所谓“虚拟语气”，从用途上区别有三种：一种用来表达与实际情况相反的虚构假设，一种用来表达“祈使愿望”的口气，另一种满足特殊的句式需要。 虚拟语气并不全是在表达虚构的情况，理解这一点非常重要。 2、虚拟语气从句式表现上有三种：表达与实际情况相反的虚构假设用were式虚拟，表达“祈使愿望”的口气be式虚拟，在特殊句式中的照句式要求而定。 3、学习虚拟语气，其目的不在于单纯解决语法问题，更不能停留在应试的层面上。
2、掌握虚拟语气的用法对英语的阅读理解非常重要，尤其是进入大学以后，这一点更为重要。 一、were式虚拟 英语中，被叫做“were式虚拟”的这种虚拟语气，通过扭曲时态形式来表示与实际情况相反的虚构假设，具体的做法是将时态的形式“倒推一个时态”。这样的表述也许不太准确，但是非常实用，也极容易理解。 具体的做法，就是将现在时态变成过去时态，将过去时态变成“过去的过去”。 在这种虚拟语气的用法中，动词be至少要倒退一个时态成为“过去时态”的were（在虚拟语气中一般不用was，is、am、are倒推一个时态以后都写成were）。因此，这种表示与实际情况相反的虚构假设的虚拟语气就就以动词be的变化为例，叫
3、做了were式虚拟。 were式虚拟主要用在wish从句，as if从句和非真实条件句。 下面我们结合具体的例子学习were式虚拟的用法：wish从句的虚拟语气用法： 英语中表达一般性的愿望（即希望）用hope这个词，wish这个词往往表达难以实现或不能实现的愿望，所以要用虚拟语气，我们可以看看具体的用法: I wish I had the money to buy the book. 这句话表达的意思是，“我现在没有钱买这本书，但是希望能买这本书，而因为没有钱，虽然有这种愿望，却也买不了这本书。” wish从句中的动词have用来表达“现在有与没有”的情况，通过一个把have“倒推一个时态”
4、变成had，had实际上表达了一个“现在没有”的概念，正好与have这个词的本义相反。 必须牢记：wish不是hope，wish要表达的是不能实现或难以实现的愿望，必须使用were式虚拟，必须通过扭曲wish从句的时态来体现这种虚拟语气。 下面的情况相同： My little brother wishes he had wings to fly up into the sky. Many people wish they could grow rich over a single night. I wish I were a millionaire to have the money to b
5、uy all that I need. Poor little Tom, an orphan, wishes he were in a family full of love and care. My parents wish I would go to college, but they know I will not. I do wish you wouldnt smoke any more.注意：上面最后一句中你不要再抽烟了，也不是不能实现的愿望，但是借用wish来表达，显得相当婉转，没有强加于人的意味，如果说成 I hope you will not smoke any more.口气
6、就过于强硬，颇有些居高临下的意味。请看下面的句子,用法上都差不多： I wish you would come and help us out. I wish you would be more respectful to your father. I wish you would stay with me for a while. I wish I had had the money to buy the book. 这句话表达的意思是，“我当时没有钱买这本书，但是我现在希望当时能买下这个本，因为没有钱，虽然现在还有希望当初能买下这本书的念头，但是这已是不能实现的愿望了。” 这时候，wish
7、从句的正常时态应该是一般过去时态，但是，因为wish要表达一个不能实现的愿望，从句只好倒推一个时态，把一个一般过去时的had扭曲成了过去完成时的had had。这时候的had had，没有过去完成时的时态意义，只是通过一种扭曲了的时态形式表达了一个“虚拟”的情况，一种不能实现了的愿望。 下面的情况相同： We all wish he had not made that silly mistake. I really wish I had not overheard what he said about me. Mr. Smith wishes that he had not spent off
8、 all his money. It was late for the criminal to wish that he had not committed the crime. Linda wished that she had been more patient and careful in the examination. I wish I had been in your place to take the challenge.（最后这一句中的had been也往往写成were，因为这时候的were也是一种扭曲了的时态形式，也能表达出这个虚拟的意味。） 再强调一次： wish后面从句的
9、动词时态形式非常重要，句中的一般过去时表示的是与现在相反的情况，过去完成时表示的与过去相反的情况，过去将来时表示的是与将来情况相反的愿望过去将来时是一般将来时倒推一个时态的结果，这是以汉语为母语的初学英语者常常注意不够的地方。 下面是人们常常使用的例句： I wish I knew the answer to the question. I wish I had known the answer to the question. I wish I could go with you. I wish I could have gone with you yesterday. 请注意上面的最后一句
10、，yesterday决定了could的过去时态，从形式上could不能倒推一个时态，为了体现“时态的倒推”（或者说时态的扭曲），could后面原本应该是一般形式的不定式go变成了完成式的形式have gone。这也是很有意思的语言现象，在各类的were式虚拟中都经常出现，非常值得注意。 当wish作名词使用的时候，其同位语从句表达的是wish的内容，也需要使用were式虚拟，例如： We all have the wish that all mankind could live peacefully together. The wish that all the classmates came
11、 back to another reunion is merely lovely dream.as if从句的虚拟语气用法： as if的意思是“好像”，从用法上有两种，一种是不知道事实的真相，说其好像一种特定的情况；另一种是明知道事实的真相，却说其好像与事实不同的情况。在后一种情况下，句子应该使用虚拟语气，谓语动词的时态形式向后倒推一个时态，而在前一种情况下，句子处于陈述语气，应该使用正常的时态形式，请比较下面的谓语形式： Mr. Sam Smith, my P.E. teacher, looks like an army officer. The stranger at the scho
12、ol gate looks like an army officer. 在前一个句子里，我非常清楚我的体育老师不是军官，而我说他看起来像军官，就用虚拟语气。 在后一个句子里，我不知道门口陌生人的身份，不知道他是不是军官，我说他看起来像军官，就不用虚拟语气。 Tom looks calm and steady as if he were telling the truth. Tom looks calm and steady as if he is telling the truth. 前一句表明汤姆是在撒谎，后一句说明汤姆可能在撒谎。 理解as if从句的虚拟语气和陈述语气的不同用法很重要，特
13、别是在 下面看一些情景练习，这些都是教学中常用的练习，包括了非真实条件句的多种情况。用上述的方法，解决这样的问题并不费力： 1. Last Sunday we all stayed indoors because it rained the whole day. 用if后，主从句从真实条件句的基础上倒移一个事态。 If it hadnt rained for a whole day, we wouldnt have stayed indoors last Sunday. 2. John and Joseph werent given the tickets, so they did not g
14、o to the cinema. If John and Joseph had been given the tickets, they would have gone to the cinema. 3. David Smith was required to leave the country within 24 hours because he had acted as a spy for a foreign country. 主句中的过去完成时“倒移”时其谓语动词不再变形，正如直接引语变成间接引语时那样：David Smith would not have been required t
15、o leave the country if he hadnt acted as a spy for a foreign country. 4. I dont like the diamond necklace, so I dont want to have it. If I liked the diamond necklace, I would want to have it. 5. Johnson was warned of the danger last night, so now he does everything very carefully. 本句和下两句是错综时间条件句，即主句
16、和从句的时态不相同，本来可以成为非真实条件句教学中的一个难题，但是现在只要按照主从句谓语动词时态形式“倒移”的规则，问题就可以迎刃而解。 If Johnson hadnt been warned of the danger last night, he wouldnt do everything so carefully. 本句和下两句是错综时间条件句，即主句和从句的时态不相同，本来可以成为非真实条件句教学中的一个难题，但是现在只要按照主从句谓语动词时态形式“倒移”的规则，问题就可以迎刃而解。 If Johnson hadnt been warned of the danger last ni
17、ght, he wouldnt do everything so carefully. 6. Joan received the invitation yesterday. She will go to the party tomorrow evening. If Joan hadnt received the invitation yesterday, she would not go to the party tomorrow evening. 7. Larry has heard from quite a few friends in China and now he knows muc
18、h about this country. Larry wouldnt know much about this country if he hadnt heard from quite a few friends in China. 8. Bob isnt here, so we cant ask him to help with the task. 在非真实条件句中be 的过去时形式一般用were： If Bob were here, we could ask hime to help with the task. 9. We will have a sports meet next Su
19、nday, so all the students will have to come to school then. 注意从句的形式： If we didnt have a sports meet next Sunday, the students wouldnt have to come to school then. If we werent to have a sports meet next Sunday, the students wouldnt have to come to school then. If we shouldnt have a sports meet next
20、Sunday, the students wouldnt have to come to school then. 关于倒装句式: 在非真实条件句中，如果条件句中有助动词be, had, should等，连接词 if 可以省略，如： Should I come late tomorrow, you could ask someone else to take my place. Should anything gone wrong with this device, you should go and check with the local dealer. Had you been here
21、 a minute late, you would have caught him cheating in the test. Had we asked him a second time, we would sure have had his advice. Were I to attend the meeting in Shanghai, I would fly there tomorrow. Were they in our place, they would have a totally different opinion of the situation. 这时候要注意，如果条件句在
22、主句后面，这种倒装的句式看着相当别扭： The whole school would not have had that silly idea of the so called invention had they noticed the date of the invention issued: April 1st. I would have taken what you said for granted had I not been to the place myself. You would get double paid were I to ask you for additional
23、 service. We would cancel the trip were the weather to be rainy. Go and check with the local dealer should the recorder not work properly. I would have to change my plan should anything wrong happens.最后再次强调两点： 、对最后一组句子还要些说明： 如果条件从句指的是将来时间，非真实条件句有三种形式： 第句：因为真实条件句指将来时间时用现在时态，倒移其时态形式，直接用一般过去时的形式； 第句：这里
24、用were to do 形式，应该指明这是由be to do 结构倒移时态形式的结果（从is(am,are) to do 到were to do）； 第句：这里用should do，可以解释为should 与were to 在此句式同义，属于同义替代。 、非真实条件是建立在与事实相反、或很难成为现实的假设基础之上，其主句是建立在这样的假设之上的推论，主句的would (could, might, should)表示着一种不可实现，或难以实现的可能性，决不能漏掉。 掌握了“时态倒移”的规律，非真实条件句的其他问题就很容易解决了。 二、be式虚拟 英语中，被叫做“be式虚拟”的这种虚拟语气，一般用
25、在名词性从句中，这些名词性从句一般都与表示祈使意义的动词有关。最典型的是，suggest, order, propose等表示祈使意义的动词的宾语从句，其谓语形式应该使用be式虚拟。 be式虚拟通过一种固定不变的谓语动词形式来表示说话者的一种“祈使愿望”，具体的做法是将谓语动词的形式固定为(should) do,不论该语句应该使用什么时态，其谓语动词的形式都是 (should) do形式。以典型的动词be举例，不论它应该是什么时态形式，只要它用来表达“祈使愿望”的虚拟，它的形式就是（should) be，或者说是be了，因此这种虚拟语气就被叫做be式虚拟。例如： We strongly sug
26、gested that the meeting be put off till the next day. The officer ordered that the spy be killed right away. Mr. Smith proposed that people from both companies gather for new ideas. I will suggest to the school board that a basketball team be set up soon. 以上几个句子中省略了should以后显得比较别扭，如果should这个词不省略，虽然看着
27、就不那么别扭了，但是还是容易出错误的。 要记住两点：1、be式虚拟中的谓语动词形式是固定不变的，不受其本身应该使用的时态的限制；2、是否在一个宾语从句中使用be式虚拟，关键看该从句是否受含有祈使意义的动词的限定。 除 suggest, order, propose 以外，这类含有祈使意义的动词还有：advise, ask, arrange, beg, command, demand, decide, desire, make up ones mind, insist, plead, recommend, require, request 等等。 这些动词不管口气强弱的程度如何，都是在“祈使”别
28、人做什么，因此虽然动词比较多，但是并不难记忆。 这些动词中，有一些动词是多义词，如 suggest 可表示“建议”也可表示“暗示、表明”, insist 可以表示“坚持要求”也可以表示“坚持认为、坚持表白”, decide (make up ones mind) 可表示“决定”也可以表示“认定、断定”, ask 可表示“要求”也可以表示“闻讯”等等, 只有当以上动词用作祈使意义的时候，受其限定的宾语从句的谓语才使用 be式虚拟。例如： The principal suggested that the vacation be cut short to two days. The smile on
29、 his face suggested that he was satisfied. My brother insisted that I give away my rights to have my fathers house. The bookseller insisted that I stole his book, but I didnt. The president decided that the trip be cancelled. The police decided that the old man was the murderer. I sincerely ask that
30、 you all attend the meeting tomorrow. Miss Smith asked if I was interested in her boat. 前面提到了be式虚拟用于名词性从句，宾语从句只是名词性从句的一种。 下面请看几个表语从句中使用be式虚拟的情况: My idea is that we begin the party with a warm welcome to Mr. Black. Their proposal was that we start out one hour earlier. We stuck to the original plan t
31、hat we have a meeting before taking actions. His request was that we help the old lady with her daily shopping. My advice is that you should not come back to this place again. What he recommended was that we give it up completely. What you should suggest to her is that she should go and see a decent doctor. (注意，最后一句话中的第一个should不能省略掉，第二个能。）请看看几个主语从句中使用be式虚拟的情况： That we go and visit the Gr
