難得 的英文怎麼說?

[1] something I haven't done in a while[2] special[3] admirable[4] On this special occasion...[5] a special occasion
  a special day
  a special effort[6] rare
  hard to come by[7] unusual
  once in a blue moon

難得有很多意思，得根據意思來正確翻譯，而且常常白話翻譯即可，例如:

Last weekend I wanted to go hiking which I hadn't done in a while.. = 難得上週末我想去爬山..

a special character trait = 一個難得的性格/品格/品行

Good opportunities are hard to come by. = 好機會很難得。

而 admirable 形容令人稱讚的特質，special 形容特別，rare 形容稀少。

unusual 跟 once in a blue moon 都指很罕見的意思。
