题目内容：

不明白这句话的里面的一句“as indifferent as if”
the frog scratch the side of his head with his hind foot as indifferent as if he had no idea he'd been doing any more than any frog might do
是as...as句型,还是as if句型?

优质解答

青蛙依旧漫不经心地用后腿抓挠自己的一侧脑袋,好像全然不知自己此举已经并非青蛙所为了.
as indifferent as if 应当这样断句：
as indifferent 是一句,表示：依旧那样漫不经心/满不在乎
as if 表示；好像,似乎,仿佛.引起虚拟语气.
