Question

下面这两句话中it和this分别指代什么呢?
1、Even sensation corresponds to some cerebral action.for an identical sensation to recur it would have to occur the second time in an unmodified brain.
2、But as this,strictly speaking,is a physiological impossibility,so is an unmodified feeling an impossibility.
以上两句话出自如下一段文字：为便于分析，句子序号已经标出
A、To these indirect presumptions that our sensations,following the mutations of our capacity for feeling,are always undergoing an essential change,must be added another presumption,based on what must happen in the brain.
B、Even sensation corresponds to some cerebral action.
C、for an identical sensation to recur it would have to occur the second time in an unmodified brain.
D、But as this,strictly speaking,is a physiological impossibility,so is an unmodified feeling an impossibility;for to every brain-modification,however small,we suppose that there must correspond a change of equal amount in the consciousness which the brain subserves.

Answer 1

你这是什么考试的题目还是你看学术专著然后看不懂找人帮你看看啊.
我觉得你是在做什么考试的题目吧.分析这样细致.
你看这句话的出处都是很专业的书籍.
这句话你提问了两次.我一百度这句话看看它的上下文的时候就看见你这两个提问.
it = an identical sensation
这是理it最近的名词.因此是最合理的猜测.因为他来自学术专著,所以他的写作都会很严谨.不会代词和所指代的词跑得太远.离太远的都是文法不好的写作.
同理,this 指C这个句子.
可以理解吗?
