A、To Build a Fire. B、Love of Life. C、The Call of the Wild. D、The Sea-Wolf D由句(1)可知，杰克-伦敦的一些著名作品是以育空为写作背景的，比如《生火》、《热爱生命》和《野性的呼唤》。

W: Hey, Tim. Recently, I have been to some lectures of American literature and I have heard that some of Jack London’s stories are set in Yukon, Canada.
M: Yes. (1) Some of his best stories happen there such as To Build a Fire, Love of Life and The Call of the Wild.
W: I see. But I wonder why. What is so particular about this region? Mr As far as I know, (2-1) Yukon’ appeal lies in its pristine nature.
W: What do you mean by pristine nature?
M: (2-2) That means tourism in this region relies heavily on appreciating the beauty of nature, and there are many organized outfitters and guides available to hunters and anglers and nature lovers of all sorts.
W: I see. (3-1) I heard that many sports enthusiasts can paddle lakes and rivers with canoes and kayaks, ride or walk trails, ski or snowboard in an organized setting. Isn’t it amazing?
M: (3-2) Or you can access the backcountry by air or snowmobile, climb the highest peaks in Canada or take a family hike up smaller mountains. It is a magnificent place for nature lovers.
W: So did I gather. I remember Yukon’s tourism motto is "Larger than life". What does that mean anyway?
M: That means Yukon has a wide array of events and infrastructures that attract artists, participants and tourists from all parts of the world.
W: I see. And I read from newspapers that in Yukon, you can have a very close look at some wild animals.
M: Including some dangerous ones.
W: And I heard that the Yukon sled dog race is quite famous, just like the one in The Call of the Wild.
M: Yes. In the past, people in Yukon depended heavily on sled dogs for transportation, especially in winters. And one thing peculiar about Yukon is that the latitude of it enables the view of aurora.
W: Wow, what a rare scene!
M: Don’t forget Yukon is also rich in a cultural sense. (4) By far, the strongest cultural and tourism aspect of Yukon is the legacy of the Klondike Gold Rush which inspired such contemporary writers at the time as Robert W. Service and Jack London.
W: (5-1) You mean the Gold Rush that took place more than a century ago?
M: (5-2) Yes. The discovery of gold in the Yukon in 1896 led to a stampede to the Klondike region between 1897 and 1899.
W: Did Jack London try his luck there in this Gold Rush?
M: Yes. But unfortunately, he did not get any gold at all. And I guess that is one of the reasons why many of his stories are based on his experience in Yukon.
W: I see. Thanks for your information on the Yukon and Jack London.
