Question

这里是形容词做主语?求前半句的语法分析,that之后的句子可以理解为愿意状语从句吗?

So ordinary and routine has this become to us that it takes a determined leap of the imagination to grasp the impact of those first moving images.

Answer 1

前半句So开头用了倒装，正常语序是this has become so ordinary and routine to us，that之后是一个结果状语从句 ，so（such）……that……的常见句型。
