Ví dụ

Clear Moon, Frost Soon. If you have a clear view of the winter moon at night, you can expect a brisk morning to follow. Without cloud cover to insulate (cô lập, cách ly) the air, the Earth’s heat rises, which causes surface temperatures to plummet (tụt xuống). This quick drop often yields a blanket of frost the next day.

I knew that farmers and other out-of-doors laborers watched the weather. Their work depended on the weather. If the hay didn’t dry, farmers could not harvest it. The adage telling farmers to “make hay when the sun shines” came about as a result. Weather maxims exist, among them these two: “Clear moon, frost soon.” “Ring around the moon, rain real soon.”
