Before we can even do sth
问题描述：
Before we can even do sth
Before we can even understand how we would come up with prosthetic devices that we may be able to use to supplant certain brain functions that have been lost,we have to model those and understand those at a computational level.
并请重点解释even用法.
答
Before we can even do sth意思是：在我们还没来得及做什么之前就……
这段话的意思是：在我们还没来得及理解我们会如何提出义肢设备这个想法之前,我们可能已经可以用它来取代那些已经失去的特定的大脑功能了,我们必须模仿并从计算机角度去理解它们（特定的大脑功能）.没有even意思不也是这样吗even再此作用类似于进一步强调，加重在……甚至就……的意味
