Startled, the man dropped his bucket down the well and spun around.

那个男人吓了一跳。水桶掉到了井里。他迅速转过身来。

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。

It’s been bucketing down all day.

【bucket】倾盆大雨已下了一整天。

Usually I would say " It's bucketing down" if it's raining really hard but if it's raining cats and dogs, it's probably best to stay inside.

如果雨真的下的很大的话，我通常会说“大雨倾盆”，但是如果说“瓢泼大雨”的话，可能最好还是待在室内。

And I remember putting the buckets down in every 20 meters or so and how the handles digged into my hands.

我记得每隔20米左右就把水桶放下，把手是如何挖到我手中的。
