蛋糕复数

蛋糕的复数形式是 cakes。无论是指一个完整的蛋糕还是指切成一块块的蛋糕，都可以用复数形式表达。例如：

1. She baked three cakes for the party.

2. They ordered several cakes for the celebration.

3. We enjoyed eating cakes at the birthday party.

需要注意的是，当提到“一块蛋糕”时，通常使用“a piece of cake”而不是复数形式“cakes”。例如：

1. I ate a piece of cake for dessert.

2. She shared a piece of cake with her friend.
