前些天,我经常到好朋友家去玩。在她家旁边的一个小池塘中洗手时,发现水面上漂浮着几块“泡沫”,觉得好玩,就用扫把把它拨到岸边。用手拿起来一看,发现它很特别,与我见到过的泡沫不同,它比泡沫稍重一些,但比一般的石头要轻得多,颜色有些灰白,表面较为粗糙,没有泡沫那样光滑。再 A few days ago, I often go to a good friend's house to play. When washing hands in a small pond next to her home, I found a few “bubbles” floating on the surface of the water, and found it fun and broombed it to the shore with a broomstick. It was unusual to find it by hand, and unlike the foam I had seen, it was slightly heavier than the foam, but lighter than usual stones, somewhat gray in color, rough in surface and as smooth as foam. again
