　　A

　　This natural wonder's extraordinary beauty let the U．S. government create the world's first national park. For a young country just coming of age in the early 1800's, the discovery of Yellowstone helped explain America's character with its wonderful landscape.

　　Today, Yellowstone's identity(身份)is closely connected with its powerful, natural geysers (喷泉) such as the ever present：Old Faithful. Old Faithful erupts about every 85 － 87 minutes. It's 130 － 140 feet tall, and it's attractive.

　　The unbelievable geysers and picture postcard landscape brought Yellowstone its fame. But today, its wildlife population is just as popular. The most arguable of these is Yellowstone's wolf population. Until recently, the wolf almost disappeared.

　　This world has been filled with killing wolves. We have been killing wolves for centuries, probably for thousands of years. Afraid that the wolves would threaten their livestock (家畜), government bounty hunters in the early 1900's killed Yellowstone's grey wolves for the price of fifteen dollars a head. They were hunted to near dying out. It would be almost a century before an effort would begin to reverse this damage.

　　In 1995，Yellowstone's wolf population was almost gone, so Douglas Smith (Yellowstone's Wolf Preservation Project leader) went to Canada to catch fourteen of the animals in an effort to revive Yellowstone's wolf population. Douglas said, "Catching a wolf is a tough thing to do. And there's nothing more exciting than flying over a wolf in a helicopter. You throw a net over them, they get tied up, and then you go up and calm them. When you move a wolf from one place to another, they try and get back home. We held them for about ten weeks inside the pens."

　　One of the transplanted wolves in particular has had a lot to do with the park's wolf repopulation. This wolf，a female known as No.9, is one of the park's top breeders，and 70% of the wolves born in the park today have her genes. Wolves are now the marquee (招牌)animal in Yellowstone. Many people said it was a lifetime experience seeing a wolf in the wild in Yellowstone.
