Swimming Holes in America
In America, these secret swimming holes are hidden and hard to reach but well worth the adventure.
Cummins Falls
Looking for the best place to escape the summer heat in the heartland of America? For more than 100 years, Cummins Falls, a scenic,75-foot waterfall located in Jackson County, TN, has been a treasure for Tennessee natives. But now, the secret is out! Although it’s a bit tough to get to, once in the park, the mountains and river provide unmatched beauty on your way to taking a swim in Tennessee's eighth-largest waterfall.
Sliding Rock
A popular place to cool off during those hot North Carolina summers, Sliding Rock waterfall is located in the Pisgah National Forest in Transylvania County. A flattened rock about 60 feet lies in a nearly 7-foot-deep pool at the bottom, making this natural waterslide a great place to visit with people of all ages.
Mooney Falls
It is the tallest water feature in the Grand Canyon, rising 190 feet above the surface. Named after an explorer in the 1800s, Mooney Falls is accessible only by crawling（爬）through 2 underground passages and then climbing down a sheer cliff（峭壁）face with just a couple of chains to hold on to. Although it is tough to get to, the view and the cool alone make it worth the trip.
Lihue Estate
A private swimming hole at the old Lihue Sugar Farm on Kauai, HI, was changed into an inner-tube water ride by Kauai Backcountry Adventures in 2003 and opened to adults. The waters for this 2.5-mile journey, which come from near the top of Mount Waialeale—one of the wettest spots in the world—are channeled through ditches（沟渠）that were hand-dug by farm workers over a century ago.

【21题详解】
细节理解题。根据第三段中的“A flattened rock about 60 feet lies in a nearly 7-foot-deep pool at the bottom, making this natural waterslide a great place to visit with people of all ages(底部有一个近7英尺深的水池，里面有一块大约60英尺高的扁平岩石，这使得这个天然的滑水道成为各个年龄段的人游玩的好地方)”可知，Sliding Rock适合各个年龄段的人游玩。一个家庭中可能有不同年龄段的人，所以Sliding Rock比较适合家庭。故选B。

推理判断题。根据第四段中的“Named after an explorer in the 1800s, Mooney Falls is accessible only by crawling（爬）through 2 underground passages and then climbing down a sheer cliff（峭壁）face with just a couple of chains to hold on to. … it is tough to get to(穆尼瀑布以19世纪一位探险家的名字命名，要进入穆尼瀑布，只能爬过2个地下通道，然后沿着陡峭的悬崖面爬下去，只能抓住几根铁链。很难到达那里)”可知，到达穆尼瀑布很难，要沿着陡峭的悬崖面爬下去，只有几根铁链可以抓。由此推之，到达那里是存在一定危险的。故选C。

推理判断题。根据最后一段中的“A private swimming hole at the old Lihue Sugar Farm on Kauai, HI, was changed into an inner-tube water ride by Kauai Backcountry Adventures in 2003 and opened to adults. The waters for this 2.5-mile journey, which come from near the top of Mount Waialeale—one of the wettest spots in the world—are channeled through ditches（沟渠）that were hand-dug by farm workers over a century ago(2003年，在夏威夷考艾岛的老利休糖厂，一个私人游泳池被考艾岛野外探险公司改成了一个内管式水上游乐设施，并对成年人开放。在这段2.5英里的旅程中，水来自世界上最潮湿的地方之一 — 怀亚利尔山的山顶附近，通过一个多世纪前农场工人手工挖掘的沟渠引水)”可知，Lihue Estate是经过人工建造而成的，不是自然形成的。而其他三个地方均为提及这一点。故这是Lihue Estate特别的地方。故选A。
