hello Fer .I hope you can understand my explication in chinese. If not , please tell me.. 它们有很大的区别。 “程度”refers to 事情发展的结果,我们理解的是事情结果的深度(deep). for exemple....I don't know how deep I love him ...(我不知道我爱他有多深。） another exemple : About the accident ,I wonder how terrible it is ..(关于这个事故，我想知道它有多严重。） “档次”在无形中，给事物分了层次,一般来说分为:好/中/差, 优/平/劣,这是人们对事物的主观评价. for exemple : When you're shopping . you have many choises ..some are dear ,some are cheap . (这里的档次是因为价格造成的,档次高的价格贵,档次低的价格低,但是在不同的人心中,档次的区分都会不同) 另外,"档次"还可以是因为人的品位造成 的. for exemple: 一些优雅的,礼貌的,举止得体的人,以及一切美好的事物,我们也可以区分档次是"高"的,而那些粗鲁,放肆,品行不端的人或者污秽的事物,我们区分它的档次是低的..ETC ....完全出于主观判断,但是,有些是被世俗的观念,约定俗成的. 题外话 :这让我联想到"时尚"与"时髦"的比较......."时尚"永远是最适合自己的风格,内在气质加上外在的包装浑然而成(something most suitable ,never out ),而 "时髦"永远追赶世界上正在风行的元素 (always run after the mode which is changing quickly),then my opinion is:时尚可以有档次之分(高雅/甜美/质朴/运动/...,但是,时髦没有.
