you look as if you've had a good time后面是与现实相反吗是真实情况还是与现实相反
you look as if you've had a good time后面是与现实相反吗
是真实情况还是与现实相反

you look as if you've had a good time后面是与现实相反吗是真实情况还是与现实相反
不是.因为从句中 you've had a good time用的是陈述语气
如果改为 you look as if you had had a good time.就是表示与现实相反的了
因为had had 在这里用的是虚拟语气.
as if 从句中是否用虚拟语气主要根据说话者的判断而定. 不一定非用虚拟语气不可

是的 与现在的现实相反！

你看起来就好像玩得很开心似的。
是与现实相反吧，其实她并不开心。

应该是相反的，要是有前后文最好结合一下，从整体的环境来分析。

as if 一般用于“虚拟语气”--最为简单的解释就是‘与真实情况相反’的用法。一般用法却是如此，但是也有特殊情况的。
这里是几个常用的：（有没有邮箱呢？我还帮你找了个文档，可是看看）。
1. 从意思上来看：
as if (= as though) 意思是“好像……，仿佛……”，是个连词，引导方式状语从句。
例如： He makes it seem as if it...

as if 一般用于“虚拟语气”--最为简单的解释就是‘与真实情况相反’的用法。一般用法却是如此，但是也有特殊情况的。
这里是几个常用的：（有没有邮箱呢？我还帮你找了个文档，可是看看）。
1. 从意思上来看：
as if (= as though) 意思是“好像……，仿佛……”，是个连词，引导方式状语从句。
例如： He makes it seem as if it were one of the best meals he has ever had.
2. 用法相对而言比较复杂一些：
as if 引导的从句经常用虚拟语气。从上面的句子可以看出，主句都是现在时态，as if从句都是过去时态，这说明as if 从句表示的意思与事实不符或者相反。
例如：
He walks as if he were drunk.
My neighbor treats the child as if he were their own son.
******（需要注意的）但是，如果句子表达的意思与事实并没有什么不符，那么就不使用虚拟语气。
例如：
He heard a noise, as if someone was breathing.
It looks as if it is going to rain.
3. 常用搭配：经常和look, seem 连用。
例如：
She looks as if she is (were) ill, because her face is pale.
It seemed as if there was a fight between the two sides.
4. as if 从句中的主语如果和主句主语相同，而且谓语动词有be, 则从句主语和谓语经常省略。
例如：
She stood at the gate as if (she was) waiting for someone.
The teacher shouted at the boy as if (he was) angry.

不是虚拟语气表示修饰或形容。而是陈述句。看起来你玩得不错嘛。
看来很有必要讲讲：as if引导的状语从句，即使用虚拟也不表示与事实相反。而表示对前句所说形容词或副词意义的形容或者修饰。
He speaks English fluently as if he were an American.
陈述语气指很可能发生的事。
The clouds are gatherin...
