基本定义

“Clean” 和 “clear” 都是形容词，但含义略有不同。

“Clean” 通常用来描述物体的卫生程度，表示没有污垢或杂物，例如：clean clothes（干净的衣服）、clean room（整洁的房间）、clean water（清洁的水）等。
例如：
Could you please make sure the kitchen is clean before you leave?（在你离开之前，你能确保厨房是干净的吗？）
I always wash my hands with soap to keep them clean.（我总是用肥皂洗手，让它们保持干净。）
The hotel room was spotlessly clean when we arrived.（我们到达时，酒店房间是一尘不染的。）

而 “clear” 则用于描述信息的清晰度或事物的透明度，表示没有混淆或障碍，例如：clear instructions（清晰的指示）、clear sky（晴朗的天空）、clear glass（透明的玻璃）等。
例如：
The speaker’s voice wasn’t clear enough, so I had trouble understanding what he was saying.（演讲者的声音不够清晰，所以我难以理解他在说什么。）
The teacher provided clear examples to help us understand the concept.（老师提供了清晰的例子来帮助我们理解这个概念。）
The company has a clear policy against discrimination of any kind.（公司有明确的反对任何形式歧视的政策。）

用法总结：
“Clean” 用来形容物体或表面的卫生程度，表示没有污垢或杂物。
“Clear” 用来形容信息或事物的透明度，表示没有混淆或障碍。
“Clear” 还可以用来形容人的思想或语言，表示没有混淆或模糊。
通常来说，”clean” 的比 “clear” 的使用更为普遍，因为我们更多地关注卫生和清洁。
