尽量详细一点，谢谢

用but的时候。一般情况下，but后面的句子根前面有某种程度上的相反
ex: I want to go home, but I can't.
ex: The shoes are Nike brand, but they are fake
ex: This dress is fancy, but it doesn't fit me
unless就像是“除非” 需要除非。。后面的句子让句子成立
ex:sports shoes were not shoes unless they were Nike or Reebok

－nike和reebok牌子的鞋子才算是运动鞋，其他根本就不算
－运动鞋根本就不能说是鞋子，“除非”它们是nike或者reebok的牌子

and用于肯定
OR用于疑问句
