2．as if/as thugh引导表语从句as if/as thugh意为“好像，仿佛”，引导的表语从句常跟在系动词(如seem，appear，lk，taste，sund，feel，smell等)之后。若表语从句所述的是非真实的情况，从句用虚拟语气；若所述的是事实或是极可能发生的情况，从句用陈述语气。The thick smg cvered the whle city.It was as if a great black blanket had been thrwn ver it.厚重的烟雾笼罩着整个城市。好像把一个厚厚的黑色的毯子扔到它的上面。

[易错提醒]that引导同位语从句和定语从句的区别：引导定语从句时，that既起引导词的作用，又在从句中充当句子成分；如果在从句中作宾语that可以省略，所修饰的名词指物时可用which替换。引导同位语从句时，that在从句中不充当任何句子成分，但不能省略，也不能用其他词替换。
