苍耳是一种常常靠动物传播种子的植物。在一片绿莹莹的草地上,长着几株苍耳,摇曳的枝头上挂着许多美丽的小苍耳。每天,小苍耳们不停地嬉戏,日子过得很快乐。有一天,苍耳妈妈看见一只麻雀在草地上找食物,她松开了手,小苍耳们纷纷落下。 Xanthium is a kind of plant that often spread seeds by animal. In a green Yingying grass, with a few strains of cocklebur, swaying branches hang many beautiful little cocks. Every day, little cocks are constantly playing and having a good time. One day, the mother of the cocklebur saw a sparrow looking for food on the grass. She let go of her hand and the small cock had dropped.
