And when you say it's 'pelting down' or it's 'bucketing down', they all mean it's raining very, very heavily.

以及" pelting down" 或" bucketing down" 其实是说大雨瓢泼。

The rain was not pelting down quite so hard.

雨下得没那么大。

There was a roll of thunder, and the rain started pelting down.

【roll】雷声滚滚，大雨开始倾盆而下。

Within an hour, a cloud of blackness would cover the planet, and burning rock and other debris would be pelting down everywhere, setting much of the planet ablaze.

不出一个小时，地球会一片漆黑，燃烧的岩石和其他碎物到处飞舞，把这颗行星的大部分地方变成一片火海。
