解释下最后一句话怎么理解
So she's basically the Greek symbol for massive inconvenience,which makes sense when you're fumbling with your too-fat fingers over a smudgy touch screen that cracks if you so much as cast a shadow on it.最后一句 if you so much as cast a shadow on it

答案

这是一种夸张的表达方式,主要是阐述那个已脏兮兮的触摸屏是如何的脆弱不堪,别说是用您的肥指头点击,就算是投下一个影子也能使触摸屏开裂!
