问题 Sometimes an object in nature is so rare that it escapes mention in nature books. Such is the case with the delightful Kirtland’s warbler. The Kirtland’s warbler is a plump, yellow-breasted bird that can be found nesting almost exclusively in the upper half of Michigan’s Lower Peninsula. Although this bird does migrate to the Bahamas during the winter months, Michigan is its natural habitat. Unfortunately, reduced numbers have caused the Kirtland’s warbler to be designated an endangered species. The remaining Kirtland’s warblers now enjoy living among the jack pine trees located in protected Michigan forests. The male warblers generally return north before the female birds. Often, they return as early as May. When they arrive, the male warblers stake out their territories and choose a nesting area. At the completion of their own long journey from the Bahamas, the female warblers begin to collect leaves and grass to build their nests. Oddly, the Kirtland’s warbler nests on the ground and not in the nearby jack pine trees themselves. During the nesting process, the male warbler provides food for his mate while the female Kirtland’s warbler lays four to five speckled eggs. The eggs hatch in two to three weeks and both the male and female warblers tend to their chicks.
In the first two sentences of the passage, the author is mostly likely suggesting that
选项 A、Kirkland’s warblers do not merit mention in nature books
B、birds that migrate are considered native to the place where they build their nests
C、many bird species are so rare that they escape mention in nature books
D、most bird species in Michigan are well documented in scientific literature
E、Kirkland’s warblers are little known because of their limited numbers
答案E
解析 The best answer is E. Choice E restates the main idea of the first two sentences. The difference between A and E is primarily that of tone. The author is slightly positive about the birds(e.g., "the delightful Kirkland’s warbler), which would eliminate choice A. Choice C is too general, while choice B refers to information later in the passage.
