如果两个字很相似的话,一个可以代替另一个,也尽管告诉我, 谢谢!!
1 分别,差别,区别
分别:"seperately".ATTENTION. It can be used as a verb, which means family or couple leave for other places for a time. As a verb, it's similar with "分离", 可以替代分别.
差别:"difference". In Chinese, it may used between superiority and inferiority.
区别:mainly as "difference", usually used to describe differences between two things but not between people.
3 形状, 形式
形状:it's mainly means "sharp" of something tangible.
形式:totally different from "形状". I don't know how to explain it, but there are two examples below.
Essays and poems are different 形式 while singing and dancing and drawing are different 形式.
4 年纪,年龄

年龄:certain number.
5. 发表,公开,公布

公开:usually means "uncover"
公布:mainly means "announce", especially some information from authorities.
6 劳动,勤劳,勤奋
劳动:mostly used as a verb or a noun, not for adjective.
勤劳 and 勤奋 are the same meaning. But I think that 勤劳 is much more used to describe somebody industrious in work, especially in physical work while 勤奋 is usually uesd to describe someone in his studying.
