"as if"和"as though"都用于描述虚拟、假设或比喻的情况，但"as though"通常跟随形容词或副词短语，而"as if"通常引导从句。除此之外，它们可以互换使用，没有本质上的区别。
以下是关于"as if"和"as though"区别的解答，大家可以先看下面的表格简单了解一下这两个词组：
as if和as though的区别：
结构形式：
as if 是常用的固定短语形式；as though 是 as if 的同义词，但在形式上更接近于完整的比较从句。

例子2：He acted as though he knew everything.（他表现得好像他什么都知道。）

例子2：He talks about the past as though he was there.（他谈论过去的事情，好像他亲身经历过一样。）

as if 后面可以直接接否定形式；as though 在否定形式时需要在 though 后添加 not。

一、文法不同
as if 引导的方式状语从句或表语从句，用虚拟语气。
例句： He acts as if he knew me. 他显得认识我似的。
as though 表示与现在事实相反，谓语动词，用would (might, could)+动词原形。
例句：They treat me as though I were a stranger. 他们待我如陌生人。
二、时态不同
as if 表示与过去事实相反，用过去完成时。
例句：This meat tastes as if it has already gone bad. 这肉吃起来似乎已经坏了。
as though 表示将来的可能性不大，用一般过去时。
例句：I feel as though I’m floating on air. 他感到好像漂浮在空中。
三、语境不同
as if 用来描述比较悲惨的境遇或者状况。
例句：It is not as if he were poor. 他不像穷的样子(或他又不穷)。
as though 语境属于中性，可以用到很多情境中。
例句：It is not as though you were going away for good. 又不是你离开不回来了。
没区别，as if与as though是一组同义词，两者意思相同，用法也相同。
as if = as though，常用来引导一个让步状语从句或表语从句，常译为“俨然”“仿佛”“好像”“犹如”，都可引导方式状语从句。例如：
He closed his eyes as though he were too tired．他闭着眼睛，好像太累了。
当从句主语和主句主语一致，从句谓语中又含有动词to be时，可以把主语和to be一起省去。
as if在使用时应注意
1、当as if引导的从句所表示的内容并不是事实或真实性很小时，一般该从句要用虚拟语气。但如果表示的内容真实性较大，就要用陈述语气。
在as if或as though引导的从句中，谓语动词用过去式（be的过去式一般用were，在口语中，主语是一、三人称时也可以用was）表示与现在实事或情况相反的虚拟：用“had+过去分词”表示与过去实事或情况相反的虚拟。
2、在非正式文体中，尤其在美国英语中，常用like代替as if。
3、as if后有时可直接跟动词不定式（短语）、分词（短语）或介词短语等。这实际上可以看作从句的简略形式。不过，as if后是虚拟语气，还是陈述语气，从字面上不易看出，要根据上下文加以判断。
4、as if前可用程度副词加以修饰或加强语气。
