由于初冬清晨气温骤降至零度以下导致人行道台阶表面凝结了薄霜，上下台阶的行人和学生一定要格外留神防滑。

As the temperature plummeted below zero in the early morning hours of winter, a thin layer of frost formed on the surface of the sidewalk steps. Pedestrians and students going up and down the steps must pay special attention to preventing slipping.

寒冬时节，室外水盆里的水在零度以下很快凝固成了厚厚的冰块。
