小知识
An addition is the act of adding something new, like a baby — a new addition to your family — or what you do in math class: the addition of columns of numbers to get the sum.
The noun addition comes from the Old French word adition, meaning “that which is added.” A new room built onto your house, a new item in a store's inventory, even another baseball cap in your collection — all of these are additions. Usually thought of as improvements, you may have heard the phrase “welcome addition” to describe a new cast mate to a television show that has lost its creative spark or a new ball field at your local park.
