回答如下:
是的,本句中的as if可以换成as though,它们的意思和功能一样,都是作方式状语从句。
as if / as though (好像,仿佛)可以引导表语从句、方式状语从句,它们既可以用陈述语气,也可以用虚拟语气,这要看它们所陈述的情况是真实情况,还是非真实情况。例如:
He looks as if / as though he were very old.
It seems as if / as though he knows it.
He talks as if / as though had been to Paris.
He eats as if / as though he has not eaten for two days.
