今天,我看到了一个太阳能摇摆叶,不用电池,不需浇水,只需光能驱动。也就是说,只要把它放在太阳下接收一些阳光,它的两片叶子就一上一下地摇摆。神奇吧!它的外表很漂亮,是个kitty猫。它的两只小耳朵 Today, I saw a solar swinging leaf, no battery, no watering, just light-driven. That is to say, as long as it receives some sunlight under the sun, its two leaves swing up and down. Fantastic! It looks very beautiful, is a kitty cat. It’s two small ears
