Similarly, cider is technically juice pressed from apples, meaning that " apple cider" is redundant, but given that now we can buy blueberry cider, peach cider, and so on, " apple cider" makes it more clear what is in the bottle.
类似地,从技术上讲, 苹果酒是用苹果榨出的汁,这意味着“苹果酒”是多余的,但考虑到现在我们可以买到蓝莓酒、桃子酒等等,“苹果酒” 更能让人清楚地知道瓶子里装的是什么。
