Passage5Questions 21 to 25 are based on thefollowing passage.Charles Darwinwas born on February 12, 1809, at Shrewsbury, England, the second son of Dr.Robert Darwin, an eminently successful physician. From his earliest youth,Darwin was passionate lover of the outdoors. As he himself said, "I wasborn a naturalist."Every aspect of nature intrigued him. He loved tocollect to fish and hunt, and to read nature books School, consisting largelyof the study of the classics, bored him intolerably. Before he turned seventeenyears old, his father sent him to the University of Edinburgh to studymedicine. But medicine terrified Charles, and he continued to devote much ofhis time to the study of nature. When it became clear that he did not want tobecome a physician, his father sent him early in 1828 to Cambridge to studytheology. This seemed a reasonable choice, since virtually all the naturalistsin England at that time were ministers, as were the professors at Cambridge whotaught botany and geology. Darwin's letters and biographical notes show that atCambridge he devoted more time to collecting beetles, discussing botany andgeology with his professors, and hunting and riding with similarly inclinedfriends than to his studies. Yet he did well in his examinations, and when hetook his B.A. in 1831 he stood tenth on the list of nonhonors students. Moreimportantly, when Darwin had completed his Cambridge years he was anaccomplished young naturalist.Immediately uponfinishing his studies, Darwin received an invitation to join The Beagle asnaturalist and companion of Captain Robert FitzRoy, who had been commissionedto survey the coasts of Patagonia, Tierra del Fuego, Chile, and Peru to provideinformation for making better charts. The voyage was to be completed within twoor three years but actually lasted five. The Beagle left Plymouth on December27, 1831, when Darwin was twenty-two years old, and returned to England onOctober 2, 1836. Darwin used these five years to their fullest extent. In hisJournal of Researches, he tells about all the places he visited-volcanic and coralislands, tropical forests in Brazil, the vast pampas of Patagonia, a crossingof the Andes from Chile to Tucuman in Argentina, and much, much more. Every daybrought unforgettable new experiences, a valuable background for his life'swork.He collected specimens from widely different groups of organisms, he dugout important fossils in Patagonia, he devoted much of his time to geology, butmost of all he observed aspects of nature and asked himself many questions asto the how and why of natural processes. He asked "why" questions notonly about geological features and animal life, but also about political andsocial situations.And it was his ability to ask profound questions and hisperseverance in trying to answer them that would eventually make Darwin a greatscientist. The Beagle was commissioned to gather information on____

The park was the first of its kind, and is known forits wildlife and its many geothermal地热的) features,especially Old Faithful Geyser, one of the most popular features in the park.It has many types of ecosystems, but the subalpine(亚高山带的)forest is dominantAmerican Indianshave lived in the Yellowstone region for at least 11,000 years. The region wasbypassed during the Lewis and Clark Expedition in the early 1800s. Aside fromvisits by mountain men during the early to mid 1800s, organized exploration didnot begin until the late 1860s. The U.S. Army was commissioned to oversee thepark just after its establishment. In 1917, administration of the park wastransferred to the National Park Service, which had been created the previousyear. Hundreds of structures have been built and are protected for theirarchitectural and historical significance, and researchers have examined morethan 1,000 archaeological sites.YellowstoneNational Park spans an area of 3,468 square miles, comprising lakes, canyons,rivers and mountain ranges. Yellowstone Lake is one of the largest high-altitudelakes in North America and is centered over the Yellowstone Caldera, thelargest super-volcano- on the continent. The caldera is considered an active volcano;it has erupted with tremendous force several times in the last two million years.Half of the world's geothermal features are in Yellowstone, fueled by ongoingvolcanic activities. Lava flows and rocks from volcanic eruptions cover most ofthe land area of Yellowstone. The park is the centerpiece of the Greater YellowstoneEcosystem, the largest remaining nearly-intact ecosystem in the Earth'snorthern temperate zone.Hundreds ofspecies of mammals birds, fish and reptiles have been documented, includingseveral that are either endangered or threatened. There are almost 60 speciesof mammals in the park. Apart from wildlife, there are 1, 700 species of treesand other plants native to the park. Another 170 species are considered to beexotic species and are non-native.As one of themost popular national parks in the United States, Yellowstone provides numerousrecreational opportunities including hiking, camping, boating,fishing andsightseeing. Paved roads provide close access to the major geothermal areas aswell as some of the lakes and waterfalls. Since the mid 1960s, at least 2 milliontourists have visited the park almost every year. Nine hotels and lodges, withtotal of 2,238 rooms and cabins, are available to tourists from all over the world.Hundreds of employees work either permanently or seasonally for the NationalPark Service. The Old Faithful Geyser is probably____
