Hit by a hammer,my foot became 3times the normal size.

问题描述:

Hit by a hammer,my foot became 3times the normal size.
请问3times the normal size是什么用法?能否具体分析一下
(我只知道表达倍数的有"倍数+as……as+名词","倍数+比较级+than+名词”和“倍数+the+size/length等+of+名词,不知道那句话里的是哪种用法)

3times the normal size就是“倍数+the+size/length”的用法,只是在“倍数+the+size”加了个normal的修饰语.
