W: Yellow Stone？ I've always wanted to spend sometime out in Wyoming.
M: Wait till you hear what the project is. She is working with the buffalo population. The herds have been increasing in size lately which is good in theory.
W: Yeah. But I thought they were in danger of becoming extinct.
M: Well, apparently because of all the winter tourists, paths are created in the snow. More buffalo are surviving the harsh winters because the paths make it easier for the buffalo to move around and find food. But it turns out that some of the herds are infected with bacteria.
W: Oh, yeah. I heard about that a blue...
M: A blue seller aborters.
W: Right, it has been around for quite a while.
M: Yes, it has. And because the buffalo population is increasing, they have been roaming more than usual. And the diseases begin to spread to the cattle ranches that border the park.
W: That's bad news. Isn't that the disease that causes animals to abort their young？
M: Yes. And it caused a lot of controversy. Some of the ranches even wanted to destroy the buffalo herds.
W: That's awful. Have they made much progress with the research？
M: So far they have been collecting tissue samples from dead buffalo to see if bacteria are present.
W: I'd really be interested in working on this. You know I've been researching diseased animal population.
M: That's why I thought of you. I took the liberty of mentioning your name to my friend. She's hoping you'll be able to spend the whole summer out there.
W: Well, I was going to work on my thesis a lot in July, but I'm sure my adviser wouldn't want me to pass up this opportunity.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
A gripping, fast-paced tale of adventure, The Call of the Wild focuses on Buck, a sheepdog stolen from a California farm and transported to the arctic. Buck's struggle to survive on the arctic trail demonstrates the uncertain nature of life in the wild. Although it is an engaging animal story, the reader cannot help but draw parallels between Buck's experience and that of humans. The book suggests that environment shapes character, and emphasizes that primitive character—often hidden beneath a layer of civilization—is never lost to the individual. Providing a fascinating glimpse of a way of life that has almost disappeared, the novel suggests that creatures survive best when they adapt to the natural world, rather than trying to impose changes on their environment.
The story begins in 1897, at the start of the Gold Rush. The discovery of gold in the Klondike—a region in northwestern Canada—prompted thousands of gold seekers to head for the far north, all of them desperately in need of dogs to pull sleds across the harsh arctic trails. Buck, a large dog who has enjoyed a leisurely life on a California farm, is stolen and shipped to the Yukon. Buck learns to survive in this cruel environment; he begins to discover the primitive knowledge of his ancestors, and in time he responds to the call of the wild. Because the book focuses upon Buck's experience, the human characters are of secondary importance. Buck is a magnificent dog, part shepherd and part St. Bernard. His superior strength enables him to adapt readily to the northern climate and the harsh demands of his labors. But he possesses one additional quality—imagination. Buck fights with his head as well as his strength. Adaptability is a dominant theme in this novel. In order to survive in the arctic, Buck must learn "the law of club and fang(牙齿)". Buck is first taught this law by the club wielding sled drivers, who show him that the strongest individuals are the ones who rule. Buck also learns this primitive law from the other team dogs, such as Dave, Solleks, and the vicious team leader, Spitz. From them, Buck learns that he must either bite or be bitten, master or be mastered.
