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.

Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive
because of warming oceans from climate change.
Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer
conditions sped up the sharks’ growing process. That meant the sharks were born earlier and very tired. The
findings could be used in the study of other sharks, including those that give birth to live young.
The scientists studied 27 sharks. Some were raised in average summer water temperatures, about 27 degrees
Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found
that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures.
They also showed reduced energy levels.
Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies
that look like decorations on some military clothing.
One study this year found that worldwide numbers of oceanie sharks and rays dropped more than 70 percent
between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten shark.
Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of
Excellence for Coral Reef Studies at James Cook University in Australia. She was the lead author of the epaulette
shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong
enough to survive for long in the wild.
She added that if the sharks are born smaller than usual “they are probably going to have to start looking for
food sooner—and they’re going to have less time to adjust to their surroundings.” The study should serve as a
warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.
4. In what aspect do the warmer conditions affect the baby sharks?
A. Their food. B. Their body weight. C. Their living habits. D. Their
moving route.
5. How did the scientists carry out their study?
A. By studying former data.
