The Grand Canyon(科罗拉多大峡谷)
The Grand Canyon, a long, narrow gorge(峡谷) in Arizona, is rich in geological history. Its record of past plant and animal life also makes it an exciting and invaluable object of study for biologists. Using samples (样品) form the two hundred and seventeen miles of the canyon’s walls, scientists analyze(分析)the building materials that form the earth’s surface and study the natural processes which have affected the canyon over its four - billion - year history. These processes include the eruption (喷发) of volcanoes, which were active as recently as one thousand years ago, and gradual decomposition (分解) by erosion(侵蚀). Scientists also study a great variety of fossils that can be found in the canyon. These imprints of past forms of life are preserved in rock. The lower levels of canyon rock contain fossils of seashells and primitive algae (原始类), while the upper levels contain fossils of such creatures as dinosaurs(恐龙)and other prehistoric land animals. All of these discoveries provide scientist with information both on the earth’s history in general and on the area around the Grand Canyon in particular.

阅读下列材料，从所给的六个选项（A、B、C、D、E和F）中，选出符合各小题要求的最佳选项，并在答题卡上将该项涂黑。选项中有一项是多余选项。
The people below are now traveling in the U.S., and now looking for a park to visit. After the description of these people, there is information about six American parks A-F. Decide which park would be most suitable for the person mentioned in questions 61-65 and then mark the correct letter (A-F) on your answer sheet. There is one extra paragraph about one park which you don't need to use.
_______1.Lisa is a naturalist. She loves the outdoors and is fascinated with adventure and all types of wildlife. Along with enjoying wildlife she also has a passion for backpacking and hiking. Lisa is also interested in photography and will climb as high as needed to get that great shot.
_______2.Martin, who is specialized in geography, would like to see a park which is filled with exciting discoveries of facts about the earth movements. He also hopes to observe the changes in rocks due to time and erosion.
_______3.Kelly, just graduated from university. Her major is archeology(考古学). She is interested in ancient finds such as: fossils of animals and plant life, old pottery and especially things dating back to the prehistoric age. Kelly hopes to unearth something significant so she can develop her career.
_______4.Simon is one for excitement. He enjoys all out-door sports especially white water rafting. He has been searching for a park that can fulfill his taste for adventure. And at the same time he can appreciate the beautiful sceneries along the way.
_______5.Chris is looking for something famous perhaps a "superstar" of parks. He is interested in everything from wildlife to Earth activities. He hopes he can find a park which can offer the most to him.
A. This park is a vast natural museum, and it is recognized as the lowest point in the U.S. All the great divisions of geological(地质的) time, the eras and most of their subdivisions, are represented（描写） in the rocks of the mountains bordering the great valley. These rocks and the land forms tell a story of endless changes in the earth's crust（地壳） - vast depositions, contortions, tilting, alternate risings and lowering, faulting and intense heats and pressures that changed the very nature of some rocks.
B. This park protects a large deposit（存放） of fossil（化石） dinosaur bones--remains of the so-called "terrible lizards" that lived millions of years ago. The dinosaurs weren't really lizards, and most of them weren't even terrible. But some of the first dinosaur fossils ever found were huge bones and teeth, very lizard-like except for their size, and so the idea of monstrous lizards was born. Today, many ideas about dinosaurs are changing, and the fossils at this park continue to help us learn more about these fascinating animals.
C. With elevations ranging from 8,000 feet in the wet, grassy valleys to 14,259 feet at the weather-ravaged top of Long's Peak, a visitor to the park has opportunities for countless breathtaking experiences and adventures. A large variety of animals will delight wildlife-watchers of all ages. Wildflower-lovers are never disappointed in June and July when the meadows and hillsides are splashed with botanical color. 359 miles of trail offer endless opportunities to hikers, backpackers and horseback riders. So far to find 60 peaks rising above 12,000 feet challenge intrepid hikers and climbers.
D. The world's largest concentration of natural stone arches is found in this park. Over 1500 of these 'miracles of nature' grace the 73,000-acre area. And it is famous for the red arches of Entrada sandstone that occur there in great profusion A 41-mile round-trip paved road in the park leads to the major sights, including Balanced Rock, Skyline Arch, and the Fiery Furnace. But there are also many other striking rock formations scattered over the park's 73,000 scenic acres.
E. Yellowstone is the oldest park in the U.S. park system and is its flagship. Visitors come to experience the park's restless geology; to see grizzlies, gray wolves, and herds of buffalo. Its turbulent（狂暴的） landscape—which remains among the most geologically active lands on the planet, with steam-spewing geysers（间歇温泉）, gurgling fumaroles, and frequent earthquakes—was protected as the world's first national park in 1872. Yellowstone and the huge tracts of national-forest land that ring it comprise one of the world's last intact temperate ecosystems—all its major species of plants and animals are still present.
F. This park has a Canyon 200 miles long and about a mile deep. Along the ride you follow the Colorado River which carved this massive canyon. At times the canyon is from 5 to 15 miles across. The Colorado River continues to shape and gouge its way through the canyon where about 90 species of mammals（哺乳动物） and some 290 species of birds live. River rafting along the Colorado River has different options for people. You can go on long trips with organizations or even take a smooth ride down the river with a picnic style lunch.
