In American English (I'm not sure about British usage), we generally put "mountain"after the name, but if it is an important mountain, we put "mount" before the name, as in Mount St.Helens, Mount McKinley, Mount Ranier. (Usually, Mount is shortened to Mt.) I think the same rule apples to lakes. Usually, "lake"is put after the name, but if the lake is large and important, "lake" is put before the name: Lake Erie, Lake Superior, etc.

峨眉山 = Mount Emei or Mt. Emei 西湖 = West Lake There is no predefined way of saying names of lakes and mountains. It depends on how it is termed in English. For example, we have a lake in the USA called "Lake Erie" but another named "Great Salt Lake". For mountains we have one called "Mount McKinley", and another called "Castle Peak", but we also have another mountain called "Regal Mountain". It just depends on how it was named.

1. Mount Emei. (**not Mountain**) 2. Lake Xihu. We don't say these things the other way round!
