"Overcast" 来源于中世纪英语 "ofercasten," 其中 "ofer-" 意为 "over",而 "-casten" 意为 "cast",即投射,指的是云层覆盖在天空之上。
"Cloudy" 来源于古英语 "clud",意为"云"。
以下是一些例句:
It's an overcast day. (这是一个阴天。)
The sky is overcast. (天空阴沉沉的。)
It's going to be a cloudy day. (今天会是个阴天。)
The weather forecast says it will be cloudy tomorrow. (天气预报说明明天会是个阴天。)
