Xiling Gorge is the largest and most downstream—eastern of the famous Three Gorges.

该句话中的 most downstream —eastern of the famous Three Gorges 怎么理解？谢谢!

【答】我认为，eastern of 是east of 的笔误。east of 等于 to the east of：在......以东。建议改为：

Xiling Gorge is the largest and most downstream—east of the famous Three Gorges.

【翻译】西陵峡是在著名的三峡以东最大、最下游的一个峡谷。
