They finally managed to climb to the top,but down the hill went the children then.

问题描述:

They finally managed to climb to the top,but down the hill went the children then.
down the hill是地点状语吗?

这是倒装句,由于介词位于句首,所以主谓全倒装
原句应为They finally managed to climb to the top,but the children went down the hill then.
就是“他们终于设法爬上山顶,但然后这些孩子们就下山了
