【聽歌練聽力】the easy way ;-): "Northwest Passage"
Northwest Passage, as seen in the picture of the wikipedia page, is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Arctic Archipelago of Canada.

"Northwest Passage" is one of the best-known songs by Canadian musician Stan Rogers. An a cappella song, it features Rogers alone singing the verses, with several guest vocalists harmonizing with him in the chorus.
The song recalls the history of early explorers who were trying to discover a route across Canada to the Pacific Ocean (especially Sir John Franklin, who lost his life in the quest for the Northwest Passage). And the song's central theme is a comparison between the journeys of these past explorers and the singer's own journey across Canada.
I put the full and very interesting lyrics below, so you can relax and focus on listening to the beautiful song, and check wth the lyrics if you like. Enjoy!
Ah, for just one time I would take the Northwest Passage
To find the hand of Franklin reaching for the Beaufort Sea
Tracing one warm line through a land so wild and savage
And make a Northwest Passage to the sea
Westward from the Davis Strait 'tis there 'twas said to lie
The sea route to the Orient for which so many died
Seeking gold and glory, leaving weathered, broken bones
And a long-forgotten lonely cairn of stones
Ah, for just one time I would take the Northwest Passage
To find the hand of Franklin reaching for the Beaufort Sea
Tracing one warm line through a land so wild and savage
And make a Northwest Passage to the sea
Three centuries thereafter, I take passage overland
In the footsteps of brave Kelsey, where his Sea of Flowers began
Watching cities rise before me, then behind me sink again
This tardiest explorer, driving hard across the plain
Ah, for just one time I would take the Northwest Passage
To find the hand of Franklin reaching for the Beaufort Sea
Tracing one warm line through a land so wild and savage
And make a Northwest Passage to the sea
And through the night, behind the wheel, the mileage clicking west
I think upon Mackenzie, David Thompson and the rest
Who cracked the mountain ramparts and did show a path for me
To race the roaring Fraser to the sea
Ah, for just one time I would take the Northwest Passage
To find the hand of Franklin reaching for the Beaufort Sea
Tracing one warm line through a land so wild and savage
And make a Northwest Passage to the sea
How then am I so different from the first men through this way?
Like them, I left a settled life, I threw it all away
To seek a Northwest Passage at the call of many men
To find there but the road back home again
Ah, for just one time I would take the Northwest Passage
To find the hand of Franklin reaching for the Beaufort Sea
Tracing one warm line through a land so wild and savage
And make a Northwest Passage to the sea
