推理过程

　　His function is analogous to that of a judge, who must accept the obligation of revealingin as obvious a matter as possible the course of reasoning which led him to his decision.

　　译文

　　他的职责与法官相似,必须承担这样的责任:用尽可能明了的方式来展示自己作出决定的推理过程。

　　点睛

　　be analogous to/with意为“和…相似”,其后的that指代之前的function。who引导的是以judge为先行词的定语从句。面as obvious a matter as possible为revealing的方式状语,其中包含as...as possible结构,表示“尽可能…”。the course of...为revealing的宾语,其中which引导的是以the course of reasoning为先行词的定语从句。reveal此处意为“展现,显示”。
