我们学校有个小山坡,上面种满了各种树木。我很喜欢去那儿玩。一天下午,我在小山坡上散步,突然,脚下发出“噼噼啪啪”的声音。我吓了一跳,低头一看,发现遍地都是圆圆的小“豆子”。它蚕豆般大小,深褐色。大概是干透了,脚一踩就是一声爆响,很像过年时放的小鞭炮的声音。这“豆子”是从哪里来的?我抬头一看,哦,原来是无患子树的果实啊。哈哈,这小“豆子”真有趣,我就叫它“爆爆豆”吧。 There is a small hill in our school, where we planted all kinds of trees. I really like to go there to play. One afternoon, I walked on a hillside, suddenly, the sound of “噼 噼 啪啪啪” was issued at my feet. I was shocked, looked down and found around are round small “beans ”. It is faba bean-sized, dark brown. Probably dry, the foot is a snapped sound, much like the small firecrackers when the New Year’s voice. Where does this “bean” come from? I looked up, oh, it turned out to be the fruit of a Sapindus tree. Haha, this small “beans ” really interesting, I’ll call it “explosion explosion bean ” it.
