问题     Nearly 60 million visitors flock to the 384 national parks across America every year. And you won’t have to wander far from home to enjoy one of these national treasures, with Michigan’s Isle Royale National Park nearby.
    Located 56 miles from Houghton and Copper Harbor on Michigan’s Upper Peninsula or 22 miles from Grand Portage, Minnesota, the park remains a wilderness haven that can only be reached by tour boat. With the exception of the Rock Harbor Lodge, which offers both rooms with private baths and more modest accommodations in the form of small cottages, the 572,000 acres that make up the 45-mile-long park are rough and untamed, threaded with hiking trails that lead to tents-only campsites. In other words, it’s wilderness the way it used to be. You’re likely to see a moose wading through mist-covered ponds at dawn in search of breakfast, gaze open-mouthed as bald eagles and osprey snag fish from Lake Superior, hear the sharp clap of a beaver slapping its tail on the water, or the lulling conversation of loons at sunset. If you’re especially lucky, you might even glimpse one of Isle Royale’s gray wolves, hunted nearly to extinction on the mainland. They’re very shy, however, so it’s more likely that you’ll only hear their eerie howl.
    Plenty of hiking trails open the area to exploration. At the park’s information center, you can find out about ranger-led interpretative hikes and walks that explain the delicate history of the island. Kids especially love learning how to examine an animal’s droppings to figure out its most recent meal. The Stoll Trail, a four-mile loop, winds through spruce and birch trees and offers a tour of the island’s history, including prehistoric Indian copper mines. It leads to scenic Scoville Point—a perfect picnic spot surrounded on three sides by the sparkling waters of Lake Superior.
    You can also rent a canoe at the Rock Island Marina and paddle down the shore to the Rock Harbor Lighthouse, an 1855 jewel, and the Edisen Fishery. Once a thriving business, the fishery today is manned by park service employees who use nets to demonstrate how lake trout, whitefish, and herring used to be caught from island waters. Their catch ends up on the dinner menu at the Rock Harbor Lodge.
    You can explore farther afield on ranger-guided day cruises aboard the park’s MV Sandy, or hop on—and off—the Voyageur II on its daily circumnavigation of the island. Reservations are essential and can be made at the information center.
    Another essential for any visit to Isle Royale is insect repellent. All those boreal bogs, beaver ponds and streams, generously replenished by heavy spring rains, create ideal conditions for breeding bugs. Mosquitoes and black flies—one ranger described them as "little but all teeth" — are at their worst in June and early July. As the weather warms up and the island dries out, horse flies and deer flies—the delta-winged B-1 bomber of the insect world—replace them. Come prepared to protect yourself; Usually a combination of head nets, bite-proof clothing and plenty of bug spray does the trick, which are available at the information center.
    The park is open from mid-April through October; Rock Harbor Lodge is open from Memorial Day weekend until just after Labor Day. [br] Which of the following is the best time to take a shower and be free from mosquitoes?

选项 A、Anytime from Apr. to May.
B、Anytime from May to June.
C、Anytime from July to Aug.
D、Anytime from Aug. to Sept.

答案 D

解析 推理题。从第二段第二句可以看出,整个公园只有Rock Harbor Lodge这个地方才提供带有私人浴室的住宿,而通过最后一段我们可以看出,Rock Harbor Lodge的开放时间为五月中旬至九月初,同时倒数第二段第三句表明蚊蝇最活跃的时期为六月到七月初,所以可以推断出八月和九月的任何时期均可以享受沐浴又可以免受蚊蝇叮咬之苦,故[D]正确。
