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.

B
As artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in
the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making
and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs
that rapidly outperform doctors in certain tasks.
Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained
on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial
factor for their success.
One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。Predicting disease outbreaks can save millions of lives by having resources ready should the worst happen. Startup
AIME has successfully combined public health data with machine learning and AI to create a prediction engine
capable of anticipating epidemics months in advance with great accuracy.
Another field where medical AIs are making rapid advances is in diagnostics(诊断学）Doctors base a lot of
decisions on information from X-ray, CT and MRI images. Speeding up. diagnoses from patient scans can rapidly
improve patient care and outcomes. Computer vision AIs use pattern recognition to work through these images
with incredible speed and accuracy. They have been able to outperform junior doctors and even senior specialists
in some tests.
Cardiologist(心脏科医生）Rima Arnaout developed an AI that beat human experts at correctly interpreting
echocardiograms(超声心动图）by 92 percent to 79 percent. She said that despite the result there is no prospect of
AI replacing human doctors any time soon. “As cardiologists, weread the images and then go to see the patient,”
she said. “So we're both reading images and practicing medicine. I don't think that the second piece will be taken
over so quickly. ”
The acceptance of AI in medicine will continue to gather pace in the future as it becomes more widespread.
4. What played a big role in helping AI systems know of human medicine?
A. Certain tasks.
B. Large data.
