5 . Humans have sailed the oceans’ surfaces for millennia (千年), but their depths remain effectively uncharted. Only about a quarter of the seafloor has been mapped at high resolution. Maps of most regions display only approximate depths and often miss entire underwater mountains or canyons (峡谷).
So a group of researchers has recruited some deep-diving experts: Elephant Seals and Weddell Seals. Scientists have been placing trackers on these blubbery marine mammals around Antarctica for years, gathering data on ocean temperature and salinity. For a new study, the researchers compared these dives’ location and depth data with some of the less detailed seafloor maps. They spotted places where the seals dove deeper than should have been possible according to the maps-meaning the existing depth estimates were inaccurate.
In eastern Antarctica’s Vincennes Bay, the diving seals helped the scientists find a large, hidden underwater canyon. An Australian research ship called the RSV Nuyina later measured the canyon’s exact depth using sonar, and the researchers have proposed naming their find the Mirounga-Nuyina Canyon — honoring both the ship and the involved Elephant Seals, genus (动植物的属) Mirounga.
But seals can’t map the entire ocean floor. The trackers used in the study could pinpoint a seal’s geographical location only within about 1.5miles. Plus, because the seals don’t always dive to the bottom of the ocean, they can reveal only where the bottom is deeper than in existing maps — not shallower. McMahon notes that scientists could improve on these data by using more precise GPS trackers and analyzing the seals’ diving patterns to determine whether they have reached the seafloor or simply stopped descending.
The current seal-dive data can still be valuable for an important task, says Anna Wåhlin, an oceanographer. The deep ocean around Antarctica is warmer than the frigid waters at the surface, and seafloor canyons can allow that warmer water to flow to the ice along the continent’s coast, Wåhlin explains. To predict how Antarctica’s ice will melt, scientists will need to know where those canyons are and how deep they go.

8 . Born to an adventure-loving mom and a National Geographic’s photographer dad, Alison Teal was already exploring the world as a baby. The family traveled the globe staying not at five-star hotels but in a six-foot-wide tent. From cold mountaintops to hot jungles, they completely involved themselves in local nature and culture.
Between journeys, they would return home to a quiet and faraway part of the Big Island of Hawaii, where they built a solar-powered oceanfront rest center. The front yard was the ocean, and Alison’s friends were dolphins. She would dive into the water and release seaweed. A dolphin would catch it on its nose or fin and throw it to the next player. Over the years, the dolphins grew to trust Alison. They looked for her and came close to her in the water.
After graduating from university, she continued her world travels. Her adventurous childhood and life skills landed her a spot in the reality show Naked and Afraid, in which she and her partner had to live on an unwelcoming island for 21 days. Alison’s deep knowledge of how to live in a wilderness saved the pair, but what shocked her was the amount of trash washed upon the shore.
“After that, I couldn’t ignore our plastic problem. I shifted my focus and started to protect our greatest resource, the ocean,” says Alison. Swimming in familiar waters back home, she also found her dolphin friends were no longer tossing (抛) seaweed to each other, but plastic. “That was distressing,” she says.
Her book, Alison’s Adventures: Your Passport to the World, is fled with travel tales and environmental lessons. She also offers free adventure films to go along with each chapter on her YouTube and TikTok. Alison believes all of us can make changes to protect the Earth and, in turn, those we love. “Whether you’re a lawyer, a gardener, an artist, a teacher or a surfer, we can all help in our own ways,” she says.

9 . Billions of insects are moving together over the sky like a black cloud. It’s a swarm of locusts. Many insects move in huge swarms. They form swarms for different reasons. Some move together to look for food or to find new homes. Sometimes insects swarm for protection. These enormous swarms can destroy food crops and harm other living things.
When something disturbs a red fire ants’ nest, out they will come. Not just one or two, but thousands of them. The fire ants swarm all over their victim. Their stings burn like fire. Each ant in the swarm can sting over and over again. The fire ants hold onto their victim with their mouth parts. Then they inject their prey with poison. Most small animals cannot survive the stings from a swarm of fire ants.
When army ants are on the move, anything in their path is prey. Even snakes can’t escape a swarm of these stinging ants. Army ants move together to look for food. They can’t see their prey, but they use smells and sounds to find their way. If they come to a river, they make a bridge with their bodies. They cling together with their legs. Then the rest of the ants can cross the bridge. There is not much that can stop these fierce and cruel ants from chasing their prey.
Insects are not the only animals that swarm. There are many others that do. Most are not harmful to people. Being close to a huge swarm of animals can be scary and dangerous. Some scientists have studied animal swarms. They have found that many swarms follow simple rules. They work together to solve problems. When they work together they are a very strong team.

10 . If you think about World Heritage Sites, you probably think of places associated with ancient art and culture and historical buildings. And of course, many of these are on the World Heritage List (WHL). These include remains of ancient cultures like Cuzco in Peru or the rock city of Petra in Jordan as well as old city centers such as Rome in Italy. Also common are places of artistic or cultural significance, like the Stonehenge stone circle in England. But the WHL contains a lot of sites that are not so obvious. Let’s look at a few of the more unusual sites on the WHL and why it is important to preserve them.
Citadel of Haiti
These monuments were built at the end of the 19th century when Haiti became independent and the many thousands of black slaves in Haiti were free for the first time. These ex-slaves built the monuments, which the WHL describes as “a universal symbol of liberty”.
Borders of France and Spain
This is an area of great natural beauty and the mountains have many interesting geological formations.
But it is also an area of small farms. The WHL has listed the site because it shows us about past European society through its landscape of villages, farms, fields, up land pastures and mountain roads.
The Darjeeling Himalayan Railway
This railway in India was opened in 1881 and is still operating today. It crosses a difficult area of mountain landscape and it is a great example of railway engineering. The WHL says that it is “the first, and still the most outstanding, example of a hill passenger railway.”
The city of Brasilia
Brasilia is a capital city that was created from nothing in 1956. The WHL calls it “a land mark in the history of town planning”. The different areas of the city and the buildings themselves were all designed at the same time so that they would harmonize with each other.
1. What’s the function of the examples of World Heritage Sites in paragraph 1?A.To highlight the importance of WHL. |
B.To exemplify sites of artistic and cultural value. |
C.To compare the differences between various sites. |
D.To draw readers’ attention to more unique sites on the WHL. |
A.Former slaves. | B.Citizens in Haiti. |
C.Active revolutionaries. | D.Haiti government. |
A.Citadel of Haiti. | B.Borders of France and Spain. |
C.The city of Brasilia. | D.The Darjeeling Himalayan Railway. |
