分析句子成分,since后面的能做主语?这是怎么个理由?
Since the laws of physics,not some arbitrary decision, have determined the general form of applied-art objects,they follow basic patterns, so much so that functional forms can vary only within certain limites.

Answer 1

since,这里是由于的意思,它引导原因状语从句,the laws of physics是从句的主语啊.
