The plane climbed until it was clear of the clouds.
飛機爬升直至穿出了云層。
The sky was full of dark masses of clouds.
天空中烏云密布。
A cloud of dust rose as the truck drove off.
卡車開過時揚起一片灰塵。
The sun disappeared behind a bank of clouds.
太陽消失在一大片云后面。
It was beginning to cloud over.
天空開始陰云密布。
The dark clouds in the sky meant that a storm was coming.
天空中的烏云預示暴風雨即將來臨。
