Ouverture des portes 的意思是

The place wasn’t entirely authentic, though. Unlikea normal Parisian apartment, the plumbing worked. There was a nice kitchen and a comfortablebed. Our building even had a tiny lift with a female voice that said, “Ouverturedes portes,” in perfect French. That is the only French phrase I mastered, andit’s a shame I don’t have much use for it.

这是2021年新高考考试英语全国卷I（全国乙卷）的阅读理解七选五中的一段。其中的Ouverture desportes 是法语。请问这个 Ouverture des portes 的意思是呀！麻烦懂法语的老师翻译一下，谢谢！

这是“门已开启”的意思, 这是电梯的自动语音播报。overture（名词）=opening  des= of the portes=doors 法语的冠词复数为les, de=of des=de+les = of the，portes是法语porte（门）的复数。由于电梯一般为两扇门，所以用复数。
