查询词典 river ice

The melted snow rushed down beneath the mist,the river ice began cracking and moving forward,and the turbid,foaming torrents began flowing more rapidly;the following Monday,from evening on,the mist dissolved,the clouds broke up into fleecy （松软的、蓬松的、羊毛似的） cloudlet s,the sky cleared,and the real spring had come.
