as if虚拟语气用法总结
as if虚拟语气用法总结虚拟语气是英语中一种常见的语法现象，用于表示与事实相反或假设的情况。
其中，as if虚拟语气是一种常用的表达方式。
在本文中，我将总结as if虚拟语气的用法及相关注意事项。
首先，as if虚拟语气常用于表示与现实相反的情况。
它可以用来描述假设、愿望、建议或命令等。
在使用as if虚拟语气时，我们常使用动词的过去式形式，与"as if"或"as though"连用，构成"as if/though + 过去式"的句式结构。
例如：1. She looks as if she were a movie star.（她看起来好像是个电影明星。
）2. He speaks as if he knew everything.（他说话好像他什么都知道。
）3. It's as if the sun disappeared.（好像太阳消失了。
）在以上例句中，as if虚拟语气用于表示与现实相反的情况。
实际上，她并不是一位电影明星，他并不是什么都知道，太阳也并没有消失。
这些句子中的as if虚拟语气让我们感受到一种与事实相反的情况。
此外，as if虚拟语气也可以用于表示推测或假设的情况。
在这种情况下，as if 虚拟语气常用于描述对过去的猜测或对现在的推测。
例如：1. It looks as if it had rained earlier.（看起来好像之前下过雨。
）2. He talks about the movie as if he had watched it.（他说起那部电影好像他看过。
）3. She acts as if she were the boss.（她的行为好像她是老板。
）这些句子中的as if虚拟语气用于描述对过去或现在的推测。
虽然我们无法确定是否确实下过雨、他是否真的看过那部电影或她是否真的是老板，但使用as if虚拟语气可以让我们对这些情况进行猜测或推测。
(完整版)asif,asthough的用法
as if, as though的用法as if 与as though 是一组同义词，两者意思相同，用法也相同，只是在口语中人们多半会用as if, 取其简短。
As if/as though 结构中的动词形式通常决定于说话人的语义意图。
试比较：I feel as if I was/were going to faint. (我感觉好像要晕倒了)I feel as if I am going to faint. (我感觉真的就要晕倒了)He walks as if he is drunk. 他已经醉了He walks as if he were drunk. 他没有醉It looks as if it is going to rain. 快要下雨了It looks as if were going to rain. 不会下雨这就是说，在某些语境中，如果不表示假设意义，就不必用过去时形式。
也就是说，如果as if后面的从句所表示的情况时真实的或很可能时真实的，则动词可以用陈述语气，在feel, look, seem, smell, sound, taste之后尤其如此。
例如：There’s H ob, talking to the ticket-collector. It looks as if he hasn’t got a platform ticket. 那不，霍布正在同检票员说话，看样子还没弄到站台票。
It looks as if it is going to rain. It seems as if we will have to go home on foot.You look as if you’ve been running. 你好像刚跑了一阵似的。
You look as if you know each other. You have acted as if you like me.The fish smells as if it has gone bad. The apple tastes as if it is sour.He looks as if he’s tired.It looks/seems as if you’re right.It smells as if it is fresh. 闻起来很新鲜。
as if-as though引导的从句中谓语动词究竟该用何种形式
as if/as though引导的从句中谓语动词究竟该用何种形式笔者常见到有些英语学习辅导资料上这样归纳as if／asthough 引导的从句中的谓语动词形式：as if／as though引导方式状语从句时，从句中的谓语动词常用虚拟语气；as if／asthough引导表语从句时，从句中的谓语动词常用陈述语气。
其实，这种说法是不准确的。
longman dictionary of contenporary english online(《朗文当代英语在线词典》，网址：http：///)中对as if／as though的词义是这样解释的：1.in a way that makes it seem that something i strue or that something is happening.(以某种方式表明某事似乎是真的或某事就要发生，笔者译)：it sounds as though she’s been really ill.听起来好像她真的病了。
(笔者译)mrs crump shook her head as if she was going toexplode.crump 夫人摇了摇头，似乎要发怒了。
(笔者译)ed to emphasize that something is not true orwill not happen(用以强调某事不是真的或某事不会发生，笔者译)：she said she’d never speak to me again.as if icared(=i do not care at all).她说她再也不和我说话，好像我很在乎此事(其实我一点也不在乎)。
(笔者译)从上面义项a)的解释和例句中可以看出，as if／asthough引导的从句中谓语动词用的是陈述语气；从义项b)的解释和例句中可以看出，as if／as though引导的从句中的谓语动词用了虚拟语气。
as if 的用法
as if, as though 用法概述as if 与as though 是一组同义词，两者意思相同，用法也相同，只是在口语中人们多半会用as if, 取其简短。
as if 和as though 用法较为复杂，以下是对其各种用法做一概述。
1．在通常情况下，as if 和as though 所引导的从句的谓语动词多用虚拟语气，表示所叙述的情况与事实相反。
具体用法如下：1)谈论现在情形的，用过去时（动词b e用were,也可用was）：Why is she looking at me as though she knew me?他为什么那样看我？像是认识我似的。
He behaves as if he owned the house. 他的样子好像他拥有这个房子。
He treats me as if /as though I were a stranger.He speaks as if he were an Englishman.2)谈论过去情形的动词形式有以下几种：a)过去式，表示过去的状态，如：He looked at me as if I were mad. 他那样看我，好像我是个疯子。
Mr. Coleman always talked as if he knew everything.但是，如果状态动词带有持续时间状语，则用过去完成时：They talked as if they had been friends for years. (高二册，第95页)Now it is as though she had known Millie for years. (《现代英语用法词典》)情态动词亦用过去时：She felt as though she could hardly endure such a life. 她觉得简直无法忍受这样的生活。
b)过去完成时，表示过去的动作先于主句动词而发生或完成，如：It was as if he had lost his last friend.“I remember,”she tells her children now, “how wild his white hair looked——as if ithad been electrified.”（高二册，第91页）必须注意的是，在指过去的动作时，即使主句是现在时，as if 从句中的动词也要用过去完成时：Y ou look as if you’d seen a ghost. 你好像是见了鬼似的。
as if, as though 用法
as if, as though的用法：这两个复合从属连词的用法和意义完全一样，但as if 在当代英语中比as though 普通得多。
As though 是书面语，比as 正式。
1）as if 引出的方式状语从句所表示的情况是事实或具有很大可能性时，通常用直陈语气。
名子的谓语我为look, seem, taste, smell, sound等。
如：It looks as if they have succeeded in the experiment. 看来好像他们试验成功了。
2) as if 引出的方式状语从句所表示的情况不是事实，而是主观想象或夸大性的比喻时，通常用虚拟语气。
从句中谓语动词一般用过去时，be 动词常用were,但在现代英语中也常见到单数was的情况。
如：The young man with long hair looks as if he were a girl. 这位满头长发的男青年看上去像个女的。
The injured man acted as if nothing had happened to him.这位受伤的男子表现得好像没发生什么事一样。
3）as if 引出的方式状语从句，当主句谓语是过去时态时，从句谓语形式常常没有什么特殊之处。
如：The lady felt as if she lost something. 这位女士好像学得丢了什么东西。
He was singing as though / if he hadn't had / didn't have a care in the world.他唱着歌，好像人世间他没有忧虑。
4）as if 引导的同一从句中所用的时态不同，意思往往不同。
请比较：* The clown looks as if he were ill.那个小丑好像害病似的。
（虚拟语气）The clown looked as if he had been ill.那个小丑过去好像生过病。
as if 在续写中的妙用 讲义 高考英语作文备考
今天，咱们的重心是：as if和as though的虚拟语气到底怎么用？如何记忆才最简单呢？as if：(强调某物不是真的)好像…一样，仿佛，似乎；(表示判断)好像，仿佛，似乎；(表示类比)好像，仿佛，似乎【例句】She works hard as if she never knew fatigue.她工作努力，仿佛从不知疲倦似的。
而“as though”的意思其实是和as if一样的，所以，重点是：意思看的明白，但是在虚拟语气里，怎么用呢？当as if从句用虚拟语气的时候，我们需要分情况去定义：1）如果从句表示与现在事实相反，谓语动词就用一般过去式。
【例句】You look as if you didn't care it.你看上去好像并不在乎。
2）如果从句表示与过去事实相反，谓语动词用“had+过去分词”。
【例句】The boy listened as if he had been turned to stone.那男孩倾听着，一动不动，好像已经变成了石头似的。
3）从句表示与将来事实相反，谓语动词就用“would/could/might+动词原形”。
【例句】It looks as if it might snow.看来好像要下雪了。
从上面三个例子中，我们会发现，as though和as if在虚拟语气中的用法是一样的。
再仔细观察下，我们会发现，虚拟语气下，所有的时态会倒退一个。
如此一来，是不是在选择谓语动词上就好记忆啦？as if 在续写中的巧妙运用as if 的常见用法1.It seemed as if 似乎...It seemed as if she was calling for her puppy to come back. 似乎她在呼唤她的小狗回来。
It seemed as if my cold heart began to melt slowly and my annoyance at him gradually gave way to guilt. 似乎我冰冷的心开始慢慢融化，我对他的恼怒逐渐转变为内疚。
as if as though引导表语从句
as if和as though都是用来引导表语从句的连词，其后的从句说明主语的状况或动作。
它们在句子中的作用和用法基本相同，可以互换使用。
在英语中，as if和as though引导的表语从句可以表示假设、比喻、类比等不同的语境。
下面将从语法、用法和注意事项三个方面来详细介绍as if和as though引导表语从句的用法。
1. 语法在as if和as though引导的表语从句中，从句通常包括一个主语和一个谓语动词，用来描述主句中的动作或状态。
例如：- She looks as if she has seen a ghost.- He speaks as though he were the boss.2. 用法（1）表达假设as if和as though引导的表语从句可以用来表示假设或假象，表明情况并非事实，而是作者的推测或臆测。
比如：- He walks as if he were in p本人n.- She talks as though she knows everything.（2）比喻和类比as if和as though引导的表语从句还可以用于比喻和类比，将一个事物或情况与另一个事物或情况进行比拟。
例如：- The house looks as if it were a palace.- The child behaves as though he were a little adult.（3）加强语气有时候，as if和as though引导的表语从句可以用来加强语气，使句子更具说服力或强调。
比如：- She acts as though nothing had happened.- It sounds as if it were a wonderful idea.3. 注意事项在使用as if和as though引导的表语从句时，需要注意以下几点：- 主句和从句的时态一致性。
通常情况下，as if和as though引导的表语从句中的谓语动词要使用与主句相匹配的时态。

as though和as if的用法
as though和as if的用法1. You know, "as though" and "as if" can be used to describe something that seems to be true but might not actually be. Like when you say "he walks as though he owns the place", it gives the impression that he acts really confident!2. Have you ever said something like "she talks as if she knows everything"? That's a great way to express that someone gives that appearance.3. Imagine this: "the house looked as though it had been abandoned for years". It really makes you picture a rundown place.4. "He acts as if he doesn't care", this really shows a certain attitude, doesn't it? It makes you feel his disregard.5. "The dog barked as though it sensed danger". It's like the dog has this sixth sense!6. When you say "she smiles as if nothing is wrong", it makes you wonder if she's really okay or just putting on a front.7. "He drives as though he's in a race". Oh man, that can be so annoying sometimes!8. "The scenery looks as if it's from a fairy tale". Isn't that a beautiful description?9. "They fought as though their lives depended on it". It really emphasizes how intense their argument was.In conclusion, "as though" and "as if" are super useful in describing situations and behaviors in a really vivid way. They help us express things that might not be exactly true but give a strong sense of how something appears or is acted out.。

又如：It looks as if it is going to rain.It looks as if were going to rain.第一例意味着快要下雨了，第二例则意味着不会下雨。
再看其她例子：There’s Hob, talking to the ticket-collector. It looks as if hehasn’t got a platform ticket. 那不，霍布正在同检票员说话，看样子还没弄到站台票。
You look as if you’ve been running. 你好像刚跑了一阵似的。
You look as if you know each other.He looks as if he’s tired.It looks/seems as if you’re right.You have acted as if you like me.It smells as if it is fresh. 闻起来很新鲜。
3. 随着语言的发展，as if后面的从句即使反映的不是事实，也可以不用虚拟语气而用陈述语气，这主要出现在口语或不太正式的文体中。
例如：With the development of these new tools, it is as if man hassuddenly become a millionaire of the mind. 随着这些新工具的发展，人好像突然间成为精神上的百万富翁似的。
Teen-agers may talk as if they know it all, but statistics tell adifferent story.The “historical present” is sometimes used in narrative when we wantto describe events vividly as if they are happening in our presence.4. 在非正式文体（尤其是美国英语）中，可以用like做连词代替as if 和as though。
例如：It looks like it’s going to rain today.She looks like she’ll win the race.I love that boy like he was my son.He looked like he needed someone to talk to, so we lent him an ear.He sat there smiling like it was his birthday. She started kissing me like we were on our honeymoon.她开始吻我，好像是在度蜜月似的。
5. as if和as though从句中的省略当as if和as though从句的主语与主句一致时，该主语和后面的动词可以省略。
于是便出现下面几种结构：1) as if +不定式He opened his lips as if (he were) to make some reply.The bee checked its forward speed, circledand then drifted slowlyover the mirrorlike surface of the pool as if to admire its ownreflection. 蜜蜂放慢飞行速度，转了几圈儿，然后在清澈如镜的水潭上空慢慢地飘过，似乎要欣赏它自己的倒影。
2) 不定式+形容词或形容词短语Carrie felt as if unable to endure such a life. 嘉莉觉得似乎无法再忍受这种生活了。
He lay still for a long while, as if dead.3) as if +介词短语He looked about as if (he was) in search of something.4) as if +现在分词From time to time Jason turned round as though (he was) searchingfor someone.John paused as if expecting Mary to speak. 约翰停下来，似乎是等玛丽开口。
Nevertheless, the bee kept exercising the wings slowly up and down,as though assessing the damage.然而，那只蜜蜂仍然在不停地慢慢上下活动着它地翅膀，仿佛在估量着所受的损害。
5) as if +名词He acts as if (he was) a fool.6) as if +副词He made that remark as if absently. 他好像是漫不经心地说了那句话。
6. 对as if-从句认识上的一个误区对于as if 的用法，一些人的认识上存在着一个误区，即把asif从句中动词的形式与主句的时态相联系。
如1993年第10期《英语自学》中《浅谈由as if (asthough)和wish引出的虚拟语气就明确指出：“在由as if (asthough)引出的表示虚拟语气的方式状语从句中，如果主句的谓语是一般时，那么其从句的谓语一般应该用动词的过去式(be用were)；反之，如果主句的谓语用一般过去时，那么从句谓语一般用“had+过去分词”。
这种认为从句动词形式受主句时态制约的观点是不符合语言实际的。
实际上，as if和asthough后谓语动词的形式与主句时态无关。
本文前面列举的一些例句足以证明这一点，《现代英语惯用法词典》上也有如下例句：He looks as if he were ill.He looked as if he were ill.He looks as if he had been ill.He looked as if he had been ill.我们在前面也有过类似的例句。
