我们家乡附近有一个山洞,清晨有时会从洞口冒出云烟般的白雾。传说这是一个仙洞,仙人曾经在这里修炼过,这雾气据说是仙人练功时呼出的仙气。虽然我们对这种传说不相信,但却对这种现象感到非常好奇。我想,这一定与气象知识有关。于是,在老师的组织下,我们对山洞进行实地考察和气象观测。 There is a cave near our hometown, and some misty white fog sometimes emerges from the cave in the morning. Legend is this a fairy cave, immortal had practiced here, this fog is said to be immortal practice cents exhaled Xianqi. Although we do not believe this legend, we are very curious about this phenomenon. I think this must be related to meteorological knowledge. So, under the teacher's organization, we conducted fieldwork and meteorological observation of the cave.
