大学英语四级语法精要：虚拟语气-that从句中
英语四级考试中的虚拟语气
英语四级考试中的虚拟语气英语四级考试中的虚拟语气虚拟语气在宾语从句中的用法是一个常见的考点，我们着重讲一下宾语从句常使用虚拟语气的几类特殊动词，以及这些动词的用法、构成虚拟语气的用法等。
下面是店铺为大家带来的英语四级考试中的虚拟语气，欢迎阅读。
一、何谓虚拟?在英语中，语气(mood)和时态，语态一样，都是谓语动词的一种形式。
表明说话的目的和意图，虚拟语气即表示说话人主观愿望或纯假设情况，动词需用特殊形式。
例如If I were a boy。
其中谓语动词用were，而不是am, shall, was, have等，是因为说话人为女士，而“我是男人”仅是其假设的语气，故用了一个在现实情况中绝不可能用到的were来表达这一虚拟的情况。
通过在I的后面加were这一词，能得知这是虚拟假设出来的情况。
常见的虚拟有两种：1. 表示非真实假设情况：If If I had left sooner, I could have caught the train。
如果早点出发，我就能赶上火车了。
(但我事实上已经错过了，对过去的假设虚拟)He talks so loud as if I were deaf。
他说话声太响，就像我聋了一样。
(但事实我没聋，对现在的假设虚拟)这种情况虚拟时，只需将谓语动词变本身的时态再变过去。
第一句话中的虚拟，本身为过去时，因此再变过去，即过去完成时。
left变为had left, could catch变为could have caught。
第二句话中，as if I am deaf，需要对现在假设，因此变为as if I were a deaf。
(不用I was deaf，避免与真实情况过去式混淆)类似表示非真实情况的`词还有wish希望， suppose假设， would rather宁愿， but for要不是等。
2. 表示建议、命令、要求等主观意愿：He suggested that a petition (should) be drawn up。
英语四级语法 虚拟语气
虚拟语气一．一般虚拟条件句(1) 与现在事实相反——If I were you, I wouldn’t worry.——If I had the book at hand, I would read the passage to you.那么，虚拟语气现在时的句型为：从句：If + 主语＋动词过去式(be 变were) +…主句：主语＋would (should ,could ,might ) + 动词原形＋…(2) 与过去事实相反——If you had gone to last night’s games, you would have met him.——If the policeman had arrived earlier, he would have seen the accident.那么，虚拟语气过去时的结构是：从句：If＋主语＋过去完成时…主句：主语＋should (或would,could,might) + 现在完成时…(3) 与将来事实相反——If he should come tomorrow, I would give him the dictionary he needs.——If Mr. Li were to do the experiment tomorrow, he might read the instructions carefully.那么虚拟语气将来时的句型是：从句：If+主语＋should (或were to )+动词原形＋…主句：同虚拟语气现在时的主句结构。
练习：1.I f this report were more accurate, it __________ an invaluable document.A.wereB.had beenC.will beD.would be(D)2.I _______ in trouble if the police had stopped me.A.wereB.would have beenC.would beD.had been(B)3.W hat would you do if war _________ out.A.breaksB.could breakC.had broken outD. were to break(D)二、在if引导的虚拟条件句中，若有were, had, should，可省去if,将were, had, should提到主语前，形成倒装。
大学英语语法-虚拟语气
虚拟语气1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。
(事实上是不知道)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. 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)Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。
它仅有两个形式，即be型虚拟式和were型虚拟式。
Be型虚拟]-----be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。
其主要用法如下：1)用于表命令、决定、建议、坚持等词语之后的that分句中这一用法又分三种情况：a)用在decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句）在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。
He ordered that all the books be sent at once.He ordered that all the books be sent at once.we propose that somebody neutral take the chair.She insisted that she go to the south for her holiday.b)用在advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。
英语专四语法总结
1.主谓一致就近原则1.由并列结构或连词（either…or，neither…nor，not…but，not only…but also，or 等）连接的并列主语，谓语动词与靠近的那个名词或代词保持一致。
2. 在倒装句和there be句型中，谓语动词与后面的第一个主语保持一致。
例句：There is a book and some pens on the desk.桌子上有一本书和几支钢笔。
3. 在强调句中，连接代词又在句中作主语，这时它应与被强调的主语保持一致。
例句：It is Ma ry’s brother who was injured in the car accident. 是Mary的哥哥在车祸中受伤了。
意义一致原则1. 当主语与谓语动词之间插入along with，with，as well as，together with，no less than，besides，except，but，including等短语时，谓语动词不受这些插入语的干扰，依然和主语保持一致。
例句：I, along with my sister, am going to Shanghai next month. 我，还有我姐姐，打算下个月去上海。
2. 英语中有一类单、复数同型的词（people，means，sheep，deer，fish等），其单、复数取决于它在句中的含义。
例句：All of the people in the country have been prepared for the great reformation.这个国家的人都已经为大变革做好了准备。
3. 多数情况下，由“what”引导的名词性从句作主语时，其后的谓语动词通常用单数形式。
例句：What I want to say is just “ T ake care!”.我只想说：“多保重！”4. 当主语与all，none，any，some等不定代词、形容词连用时，应根据具体句意，来决定其后的谓语动词的单复数。

虚拟语气4-虚拟语气用在其它状语从句中虚拟语气4-虚拟语气用在其它状语从句中IV. 虚拟语气用在其它状语从句中1．虚拟语气用在由as if, as though 引导的方式或让步状语从句中，一般情况下，如果主谓语动词为现在时，从句谓语多用过去时；如果主句谓语为过去时，从句谓语多用过去完成时。
虚拟语气用在 even if, even though, whatever引导的状语从句中，从句谓语可参照由if引导的虚拟条件从句的谓语，一般用过去时或过去完成时。
例如：This old machine runs as if it were a new one.The old worker works as though he were a young man.Even though she had been here very soon, she would not catch the train.Example:He has just arrived, but he talks as if he ______ all about that.a. knowb. knowsc. knownd. knewI can’t stand him. He always talks as though he _____ everything.a. knewb. knowsc. has knownd. had known______ I used a lot of examples I still could not get my idea across.a. Sinceb. But thatc. Now thatd. Even though2. 虚拟语气用在so that, lest （唯恐）, in case （万一）, unless, in order that（为了，以便）, that（为了，以至于）, for fear that （生怕，以免）, on condition that （如果）等引导的目的，条件状语从句中，从句谓语 may 或 might+原形动词，也有用 should, can, could+原形动词构成的。
形容词名词后that从句中的虚拟语气-四级语法
It＋be＋adj．／n．＋that＋主语＋虚拟语⽓，有的认为主语从句中谓语动词的形式统统是"（should ＋）动词原形"，就是说should可⽤可不⽤。
其实不然，有些形容词／名词后 that从句中的should是必⽤的。
⼀、先说形容词A．⽤it充当主语下列形容词之后that从句的虚拟语⽓必须⽤ should：incredible令⼈难以置信的，natural⾃然的， strange奇怪的，absurd 荒谬的，amazing令⼈惊慌的，annoying令⼈烦恼的，astonishing令⼈震惊的，impossible不可能的，interesting有趣的，ludicrous滑稽的，normal正常的，odd古怪的，queer奇怪的，ridiculous可笑的， silly傻的，surprising令⼈惊奇的，unnatural反常的，unthinkable不可思议的，wonderful奇异的等。
例如：1）It is absurd and ridiculous that he should behave so！他竟然如此表现，真是荒唐可笑！2）It's astonishing that she should say that sort of thing to you．她竟然对你说出那样的话，令⼈震惊。
3）It is natural that economic crises should arise in capitalist countries．资本主义国家发⽣经济危机，是很⾃然的事情。
4）Do you think it's normal that the child should be so tired？这个孩⼦这样疲倦，你认为正常吗？5）It is odd ／strange that he should do that．他竟然那样⼲，可真奇怪。
6）It is surprising tht they should choose this method of passing the evening．令⼈吃惊的是，他们竟然选择这个⽅式来度过夜晚。
