一片树叶落到平静的湖面上,几乎没什么影响,连波纹也依旧,但树叶却悠悠然浮在水面,如小船飘浮被风吹在一边;一颗石子掉到湖中,“啪”一声,水花四溅,涟漪扩散,而石子却转瞬即沉没,一直沉到湖底,待到水落还会“石”出。请以“浮沉”为话题,写一篇文章,立意自定,文体自选,题目自拟 A leaf fell on a calm lake, almost no effect, and even the ripples remained, but the leaves were leisurely floating on the surface, such as a boat floating by the wind blowing on the side; a stone fell into the lake, “click”, splash Splashing and spreading, the stone sinks instantly and sinks until it reaches the bottom of the lake. Please write an article with the theme of “floating” and be determined by yourself.
