请教这句话的语法（特别是后面的两个定语从句,in怎么能提到as前,还有a matter怎么能放在两个as之间）...
请教这句话的语法（特别是后面的两个定语从句,in怎么能提到as前,还有a matter怎么能放在两个as之间）：His function is analogous to that of a judge,who must accept the obligation of revealing in as obvious a matter as possible the course of reasoning which led him to his decision.

Answer 1

in 的宾语是matter,as obvious as possible 是用来修饰matter的短语而已.
整个句子来说,His function是主语,that 是形式表语,who.则引导一个定语从句来修饰judge（法官）.
