1 . It has been more than 40 years since anyone spotted a Japanese river otter (水獭). And the once common Tangtze River dolphins have either disappeared or are very rarely seen.
A huge challenge scientists and conservationists encounter is tracking species facing extinction in order to help them.
In Brazil, AI quickly analyzed over 150, 000 satellite images, revealing that the world’s largest tropical wetlands lost 74 percent of its surface water.
The use of AI has helped to accelerate action and increase conservationists’ ability to protect the natural world for generations to come.
| A．Give animals on the edge of extinction a fighting chance to survive |
| B．In Zambia’s Kafue National Park, home to more than 6, 000 elephants |
| C．Not until that revelation (揭露) were authorities aware of how desperate the situation was |
| D．Saving them was challenging because their whereabouts (行踪) were relatively unknown |
| E．These are just a few of the species that have been listed as extinct or locally extinct in recent years |
| F．However, because of weather conditions, researchers knew next to nothing about their winter behavior |
| G．This is where AI has brought about a revolution in the way data on these species is collected and analyzed |
2 . Being minimalist is about intentionally reducing your possessions to the items you value most and increasing the amount of time you spend on the people and activities you truly enjoy. It can take many forms.
Try clearing away your possessions
If you think hard, you will realize that the physical things you own are not the most important parts of your life. In this case you can clear away all but the most essential things in sweeps. Focus on keeping things that you value deeply.
You must have many friends, but how many of them are people who motivate and inspire you to grow and learn? Becoming minimalist means that you evaluate how well they fit into your ideal life and maximizing your social time spent on people who lift you up. Then you can also free up more time to spend on other priorities in life.
Take time for introspection
Introspection, which means you sitting with your own thoughts, is what people are terrified of in so “busy” a world.
Even though everyone embraces minimalism differently, each path leads to the same place: a more meaningful life with more time and more freedom. Hopefully you will get there.
| A．Have less possessions to enjoy more |
| B．Anyway, you should make space to think |
| C．People are eager for another way of living |
| D．Consider your lifestyle around relationships |
| E．Get rid of things that you don't need any longer |
| F．It’s worth focusing your time on people that matter |
| G．The important part is to figure out your flavor of minimalism |
There are many things in senior middle school that I still remember clearly. I studied three years in a country school, which is faraway. However, it has a good environment and strict but kind teachers, so I loved the school and all my teachers very much.
One Friday, just as we began to read books in reading class at our desks, our teacher, Mrs. Hill, said that she needed to be out of the classroom for a few minutes. She asked the class to read in silence while she was gone. And she said that those who didn’t read books in silence would have to be punished when she returned. It was well-known that Mrs. Hill was strict. So we had to be on our best behaviour.
But that Friday, Mrs. Hill hadn’t been gone for ten seconds before some students in the classroom started to talk. From one corner of the room I heard Josh ask Nick, “Can I trade my candies for your toy?” At the other end of the room I heard Samantha tell Kayla, “Let’s sit together on the bus for the museum field trip tomorrow.” And so it went all around me, until about half of the students communicated with each other.
After a while, I, too, forgot about Mrs. Hill’s instructions. I turned back and asked my friend Liza, “Can I borrow your storybook and keep it for a day?” As soon as the words were out of my mouth, Mrs. Hill walked into the classroom. The whole class returned to silence immediately. And we were full of fear.
Mrs. Hill slowly looked around the classroom and said, “If you were talking while I was gone, then please stand up.” The guilt (内疚) suddenly weighed heavily on me. “I shouldn’t have talked while she was not in the classroom. And now I should be honest and admit my mistake bravely. This is what my parents have always told me.” I thought. Then, I summoned up (鼓起) my courage to stand up, worried about the punishment that waited for me. Then I looked around.

____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________For most people, adopting (收养) a pet is one of the best decisions that they can ever make in their lives. In addition to giving an animal a home and a loving family, the owner will find the company of a pet brings more happiness than expected.
For someone like Maria, having a pet was very suitable. She was all alone after moving to a new apartment in Brazil, which made her feel lonely.
So when she found a cute black puppy named Chips, she knew she had to take him home. Maria thought that Chips would be able to fill the emptiness that she had been experiencing from living all alone.
Maria was right. Once she took the puppy home, they immediately bonded. However, as Maria had to work during the day, she was worried about leaving Chips home alone in her apartment. She was also worried that his crying would upset her neighbors.
One night, when she returned home, outside her door was a package with a folded note attached to it. Maria knew that she was in trouble. She hoped that she would not be evicted (驱逐) from her new apartment because of Chips. She loved Chips so much, and she was afraid that she might have to get rid of him because he made too much noise whenever she was away. Maria was frightened and wondered who could have left it at the door because she had little contact with the people in the building except her neighbor, Angelia. In fact, they only said hello few times.
However, when she noticed the names on the folded note, she found that it wasn’t addressed to her but to her dog, Chips, and that it was “written” by another dog named Corote. Maria opened the package first and found a few toys for pets.

Curious, Maria opened the note and started reading it.

5 . Say many things, and people will remember none. Say some things, and people will remember some. Say ONE thing, and people will remember ALL. Want to express clear viewpoints?
Express more, explain less.
Limit paragraphs to three sentences. If you’re writing your idea in a document or email, try to make paragraphs to three sentences or less. This makes it easier for readers to understand your points because they have less content to process. And because you’re writing in short, direct points compared with long pieces of text, you may find yourself writing less overall.
Hear your own words. No matter how much you review your own, writing, hearing it aloud will always identify places to cut.
| A．Remove unnecessary ideas |
| B．Know your “Need-to-Know” |
| C．These four tips shouldn’t be missed |
| D．You can’t change the style of your writing |
| E．Explaining is often an understanding behavior |
| F．Everyone benefits from applying this writing rule |
| G．You can read it aloud yourself to find out the words |
6 . Are you a fan of outdoor adventures? Do you enjoy scenic views to relax? Look no further, as the following destinations offer all that and more.
Athabasca Falls
Alberta, Canada
Water from the Canadian Rockies flows down into the waterfalls of Jasper National Park, creating a flow with wild energy. The falls are wheelchairs accessible, with a paved path taking admirers to a number of viewpoints. If visitors leave the path, they can explore both the upper and lower regions of the trail.
Akaka Falls Trail
Hakalau, Hawaii
A short half-mile hike is big on sights and low on hard activity. The well-kept ring like trail guide visitors around to see a number of waterfalls, including the 442-foot main attraction, and beautiful local flora (植物群) among the famous landscape. Though there are no hills to climb, there are a number of stairways to go.
Nugget Falls
Juneau, Alaska
Located in Tongass National Forest about 12 miles from Juneau, the Mendenhall Glacier has produced Nugget Falls, a fan-like waterfall that leads into a lake. A series of short hikes allows for different views of the waterfall and icy surrounds, which are also known for frequent brown bear sightings.
Yosemite Falls
Yosemite Valley, California
Yosemite National Park is one of the oldest national parks in America and home to the fifth tallest waterfall in the world. Hikers can reach it by taking a 1-mile trail from the lodge or the 7.2-mile round-trip Yosemite Falls Trail route. Late spring is best, with the highest water flow. In the winter, the temperatures dip below freezing. A park admission fee applies.

8 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.
As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).
With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.
The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.
“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.
“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

9 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

Jianbing is one of China’s most popular street breakfasts.
Contrary
Jianbing has a longer history than almost any other Chinese street food. Thought to have originated in Shandong Province during the Three Kingdoms Period, military strategist Zhuge Liang had his soldiers cook food on shields(盾)
Of course, if Jianbing were that easy to make, it would have taken the world by storm long before now. Part of
