Videos shared on social media showed a flooded underground railway station, water gushing down escalators, flooded platforms and buses swamped with water.

社交媒体上分享的视频显示，一个地铁站被洪水淹没，水从自动扶梯上涌下，淹没了站台，公交车也淹没在水中。

And then also as an adjective, coming back to the sort of preposition type of meaning, the " down escalator" .

然后也作为形容词，回到那种介词类型的意思， “向下的自动扶梯” 。

" Shall we take the up escalator or" , then before " down" , " d" is a consonant, so: " thuh, the down escalator" .

“我们该乘上行扶梯还是”，之后是" down" ，“d”是一个辅音，所以发音“thuh down，下行扶梯”。

You might say: " Shall we take the up escalator or the down escalator? " Okay, so which one would you use?

您可能会说：“我们应该乘坐上行自动扶梯还是下行自动扶梯？”好的，那么您会使用哪一个？

So, you can have the " down escalator" - the one that goes down; you can have the " up escalator" - the one that goes up.

因此，您可以拥有“下行自动扶梯”——向下的那个；您可以使用“上行自动扶梯”——向上的那个。
