Yellowstone National Park is the flagship of the National Park Service and a favorite to millions of visitors each year. The park is a major destination for all members of the family.

How much is the entrance fee?

$25 - Private, noncommercial vehicle;

$20 - Motorcycle or snowmobile (winter);

$12 - Visitors 16 and older entering by foot, bike, ski, etc.

This fee provides the visitor with a 7-day entrance permit for both Yellowstone and Grand Teton National Parks.

A $50 park annual pass provides entrance for a single private non-commercial vehicle at Yellowstone and Grand Teton National Parks. The $10 Interagency Senior Pass (62 and older) is a lifetime pass available to U.S. citizens or permanent residents.

Where can you stay?

Inside Yellowstone, you can choose to stay in modern or historic hotels and cabins inside the park like the Old Faithful Inn, the world’s largest log structure.

In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature — that’s what accounted for all its hot springs and other steamy features. But Christiansen couldn’t find the Yellowstone volcano anywhere.

Most of us, when we talk about volcanoes, think of the classic cone(圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma(岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn’t involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn’t find the caldera anywhere.

Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors’ centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera: almost the whole park—2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.

1.What puzzled Christiansen when he was studying Yellowstone?

A.Its complicated geographical features.

B.Its ever-lasting influence on tourism.

C.The mysterious history of the park.

D.The exact location of the volcano.

2.What does the second paragraph mainly talk about?

A.The shapes of volcanoes.

B.The impacts of volcanoes.

C.The activities of volcanoes.

D.The heights of volcanoes.

3.What does the underlined word “blow-up” in the last paragraph most probably mean?

A.Hot-air balloon. B.Digital camera.

C.Big photograph. D.Bird’s view.

（题文）After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

What does the underlined word ＂displaced＂ in paragraph 2 mean?

A. Tested.　　 B. Separated.

C. Forced out.　　 D. Tracked down.
