很多植物在天气变化之前都会表现出特别的反应,人们可以通过观察它们的特有反应,来预测天气变化。柳树在夏季里,树叶下垂,随风摇摆,赏心悦目。但如果发现柳叶变白,就预示着阴雨天气将会来临。其实,仔细观察就会发现,并非柳叶变白,而是柳叶在阴雨天前会全部反转过来,而柳叶的反面是浅绿色的,表面还带一层“白霜”。如果你有兴趣,不妨在夏秋时节的阴雨前后观察验证一番。 Many plants show special reactions before the weather changes, and people can predict changes in the weather by observing their specific responses. Willow trees in the summer, the leaves drooping, swaying, pleasing. However, if found willow white, it indicates that rainy weather will come. In fact, careful observation will find that not the willow white, but the willow in the rainy days will all reverse, and willow the opposite is light green, the surface also with a layer of “white cream.” If you are interested, may wish to observe and verify before and after the rainy season in summer and summer.
