壹苹派生活美语　嗅一嗅～有没有闻到下雨的味道？

　　Have you ever noticed how the smell in the air changes as it starts to rain? The refreshing scent that appears during rain has a scientific name: petrichor. It is a unique, earthy smell that many people find calming and nostalgic. This scent primarily comes from a natural compound called geosmin, which is produced by certain bacteria that grow in warm, damp soil. These bacteria release geosmin as part of their life cycle, and the compound builds up in the soil during dry periods.

　　你有没有注意过，当开始下雨时，空气中的气味会发生变化？这种在下雨时出现的清新气味有一个科学名称：petrichor。它是一种独特的泥土味，许多人认为这种味道让人感到放松且充满念旧之情。这种气味主要来自一种叫作土臭素的天然化合物，它是由某种生长在温暖潮湿土壤中的细菌所产生的。这些细菌在其生命周期中会释放土臭素，在干燥的时节，这种化合物会在土壤中累积。
