Unformatted text preview: tion to finding an increase of suitable browse, like huckleberry and vine maple, Arthur Einarsen, longtime game biologist in the Pacific Northwest, found quality of browse in the open areas to be substantially more nutritive. The protein content of shade­grown vegetation, for example, was much lower than that for plants grown in clearings. Paragraph 1: Two species of deer have been prevalent in the Puget Sound area of Washington state in the Pacific Northwest of the United States. The black­tailed deer, a lowland, west­side cousin of the mule deer of eastern Washington, is now the most common. The other species, the Columbian white­tailed deer, in earlier times was common in the open prairie country, it is now restricted to the low, marshy islands and flood plains along the lower Columbia River. 1. According to paragraph 1, which of the following is true of the white­tailed deer of Puget Sound? ○It is native to lowlands and marshes. ○It is more closely related to the mule deer of eastern Washington than to other types of deer. ○It has replaced the black­tailed deer in the open prairie. ○It no longer lives in a particular type of habitat that it once occupied. Paragraph 2: Nearly any kind of plant of the forest understory can be part of a deer's diet. Where the forest inhibits the growth of grass and other meadow plants, the black­tailed deer browses on huckleberry, salad, dogwood, and almost any other shrub or herb. But this is fair­weather feeding. What keeps the black­tailed deer alive in the harsher seasons of plant decay and dormancy? One compensation for not hibernating is the built­in urge to migrate. Deer may move from high­elevation browse areas in summer down to the lowland areas in late fall. Even with snow 153 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 on the ground, the high bushy understory is exposed; also snow and wind bring down leafy branches of cedar, hemlock, red alder, and other arboreal fodder. 2. It can be inferred from the discussion in paragraph 2 that winter conditions ○ Cause some deer to hibernate ○ Make food unavailable in the highlands for deer ○ Make it easier for deer to locate understory plants ○Prevent deer from migrating during the winter 3. The word "inhibits" in the passage is closest in meaning to ○ Consists of ○ Combines ○ Restricts ○ Establishes Paragraph 3 在 The numbers of deer have fluctuated markedly since the entry of Europeans into Puget Sound country. The early explorers and settlers told of abundant deer in the early 1800s and yet almost in the same breath bemoaned the lack of this succulent game animal. Famous explorers of the North American frontier, Lewis and Clark had experienced great difficulty finding game west of the Rockies and not until the second of December did they kill their first elk. To keep 40 people alive that winter, they consumed approximately 150 elk and 20 deer. And when game moved out of the lowlands in early spring, the expedition decided to return east ra...
