这天,我和妹妹在家里帮妈妈煮白萝卜。只见新鲜的白萝卜,表皮是白色的,切开看,里面同样是白色的。可是我们把萝卜放在水中煮了一段时间后,却发现白萝卜从原先不透明的白色变成近似于无色透明了。 这是什么原因?我和妹妹都不知道。妹妹可是个“小好问”,不知道的事情还非得打破沙锅问到底不可,在她的“纠缠”下,我只好带着她一起去请教自然老师。 This day, my sister and I cook white radish at home. I saw fresh white radish, the skin is white, cut open, which is also white. However, after we boiled the radish in water for a while, we found that the white radish turned from the opaque white to almost colorless and transparent. What is the reason? Neither my sister nor I know. Sister, but a “little good question,” do not know things have to break the casserole asked in the end, in her “entanglement”, I had to go with her to consult a natural teacher.
