• dry

  General everyday word for something with no moisture at all; used for objects, skin, weather, or land, with no implication about rainfall or plant life.

  日常通用词，指完全没有水分，可用于物品、皮肤、天气或土地，不涉及降雨量或植物生长的问题。

• arid 本词

  Specifically describes a climate or land that gets very little rain, too little for most plants to grow; a stronger, more technical term used mainly for climates and regions, not everyday objects.

  专指降雨极少、大多数植物难以生长的气候或土地；语气更强、更专业，主要用于描述气候和地区，不用于日常物品。

  This arid landscape sees less than two inches of rain a year, so plants rarely survive.

  这片干旱的土地一年下不到两英寸的雨，因此植物很少能存活。

Dry and arid both mean lacking moisture. Dry is the general everyday word, used for any object, skin, weather, or land with no water. Arid describes a climate or land with very little rain, too dry for most plants to grow; it is more formal.

dry 和 arid 都表示“干的”，但 dry 是日常通用词，可以形容任何缺水的东西；arid 专指降雨稀少、难以维持植物生长的气候或土地，语气更强、更书面化。这里不比较 dry 表示“不甜的（酒）”或“枯燥乏味的（幽默）”等其他义项。
