释义
adj.
Not allowing water to pass through; able to keep water out completely
防水的,不透水的
v.
To make something resistant to water
使……防水,给……做防水处理
词根拆分
原生英语water + proof。这里 proof 表示「能抵御、起防护作用」——和 foolproof、bulletproof 里的 proof 同义。所以 waterproof = 能完全抵御水。既作形容词(waterproof jacket 防水外套),也作动词(waterproof a tent 给帐篷做防水)。
词根 water 还连着 16 个词常用搭配
- 1.waterproof jacket防水外套
- 2.waterproof coating防水涂层
- 3.fully waterproof完全防水
- 4.waterproof material防水材料
例句
- 1.

易混词辨析
waterproof 和 water-resistant 的区别——waterproof 号称完全挡水,浸没也行;water-resistant 只是延缓进水,应付小雨、泼溅。营销常模糊二者,所以「防水 30 米」的表并不等于真正 waterproof。
