"China will have 75 percent of its wild animals and 80 percent of its wild plants on land under the national key protection system by 2025," the National Forestry and Grassland Administration said. So far, the national key wildlife protection rate (rise) to 74 percent, up from 71 percent last year. Its announcement coincided with the International Day for Biological Diversity, theme this year was "Building shared future for all life".

The administration said that China's (achieve) in protecting wild animals are partly attributed to releasing wild species into nature reserves after artificial breeding.was said that nine milu deer fawns (小鹿) were recently born in the Daqingshan National Nature Reserve in the Inner Mongolia autonomous region. The fawns were released into the wild in September (follow) artificial breeding in Beijing and Jiangsu province.

"This result showed that close monitoring and health management by researchers led to the successful reintroduction of the deer the wild," the administration said. Artificial breeding has helped to increase the population of some species that had (previous) disappeared in the wild. As for other wild populations, the panda population has increased from 1,114 in the 1980s to 1,864, the number of wild Asian elephants also increased from about 180 to 300 over the same period. Up to now,206 species of rare and (endanger) plants have returned to the wild, of which 112 are unique to China.

Saban has focused much of her research on what she calls "matching markets," and she's been particularly fascinated by online dating. In one study, she and several coauthors partnered with a major U.S. dating platform to explore how updates to the app's algorithm could improve outcomes for romantic hopefuls looking to spark new connections.

Analyzing data from the app, Saban developed a model that not only prioritized potential matches based on a user's preferences but also took into account the likelihood that the person on the other side of the potential match would be interested. "I not only want to show you people that you will like, I also want to show you people that will like you back," Saban notes. Factoring in users' history, activity levels, and this two-sided approach to preference led to a substantial increase in matches during field experiments in Texas. "Our algorithm increased the number of matches by 27% in Houston and by over 37% in Austin," Saban says.

Similarly, when working with the volunteer matching platform VolunteerMatch, Saban identified an imbalance in how volunteer opportunities were being distributed. Some organizations were receiving an overwhelming number of sign-ups, sometimes even more than they needed, while others struggled to attract any volunteers at all. By adjusting the search algorithm to consider the number of volunteers an organization needs and has already received, Saban and her team were able to ensure a more reasonable distribution of volunteers across opportunities.

The technical details of algorithms may be complicated, but our commitment to fairness and equity doesn't have to be. If we want algorithms to work for good, we need to make conscious choices about how we design them.

We don't need to stick to just our armchair-philosophizing, however. Thanks to the wonderful combinatory magic genetics pulls off at each birth, we've had a few individuals on Earth who are unable to forget anything. Solomon Shereshevsky, for instance, could memorize lists of arbitrary (任意的) numbers, words, and nonsense syllables with perfect recall, even decades later. At first glance, this sounds like a superpower. But Shereshevsky described it as exhausting, distracting, and emotionally unbearable.

What most miss about forgetting is that it is not a design flaw (缺陷). It's a feature. In fact, the ability to forget is fundamental to learning. It's what gives us focus, highlights the signal through the noise, and lets the brain determine what matters most given the context we are in.

Research suggests that forgetting is an active process involving brain regions like the hippocampus and prefrontal cortex, which help us manage the inflow and outflow of information. Forgetting is not our memory failing on us as much as it is our memory being better used.

And here is where we meet the concept of the forgetting curve (曲线). First described by Hermann Ebbinghaus in the late 19th century, the forgetting curve tracks how quickly we lose information over time without reinforcement (巩固). Within hours of learning something new, we begin to forget it. Rapidly at first, then more slowly over time. The key insight of those who have followed Ebbinghaus is that this curve is not fixed. On the contrary, it's something we can reshape, a feature we can tune ourselves.

For thousands of years, people have looked to the starry sky and wondered what, or who, is out there. In the early 1600s, Galileo was the first (use) his telescope to explore the sky and since then, telescopes (improve) continually.

One major breakthrough came in 1990, when the Hubble Space Telescope (launch). That Hubble is based in space allows it to see further than ground-based telescopes, and it allows scientists to learn more about the universe. Hubble (observe) have played a crucial role in the discovery of the (mystery) dark energy. Hubble was followed by the Kepler Space Telescope in 2009. Kepler' scientific goal is to search for Earth-size planets (orbit) other stars. life on other planets does exist is yet to be proved, but the signs are promising: Kepler has detected many suitable planets that are almost the same size as the Earth.

In recent years, China has developed advanced telescopes as well. One example is the innovative FAST, is the largest single⁃dish radio telescope in the world. With a dish the size of 30 football fields, FAST is able to carry monitoring with extraordinary sensitivity. One of its scientific goals is to detect communication signals between the stars in the universe.

It is clear that telescopes are crucial tools for space exploration and that developing the required technology will help astronomers all over the world make exciting discovery. How much we will learn from the telescopes is merely limited by (we) imagination.

This is wrong, as was the rapper's motto. I don't believe that eradicating bad feelings is the path to a good life. We have an opportunity here to judge the benefits of negative emotions and experiences instead of trying to push them away.

Negative emotions exist to keep us safe. The main negative emotions include sadness, anger, fear and disgust (厌恶). We experienced them in an unconscious way in response to environmental stimuli (刺激). You never say to yourself, Hey, I think I'll feel afraid now—you just feel it and react with fight or flight, which can save your life. Disgust similarly warns us unconsciously of potential illness.

Negative emotions can also make us more effective in our day-to-day activities. In an article in the journal Psychological Review, two evolutionary psychologists argue that sadness—and even depression—have existed in the face of evolution (进化) because they bring cognitive benefits. Sadness can make us more productive at work by improving focus and helping us learn from mistakes. This is how failure, by means of the resulting negative emotions, can help lead to later success.

Finally, negative emotions make us stronger for when there is a true emergency. Research shows that "stress vaccination training" — in which people learn to cope with anger, fear and anxiety by being brought up to stimuli that cause these feelings — is effective in creating emotional toughness.

In sum, if we want a life full of deep meaning, true love, and emotional strength, it's going to involve the risk of discomfort, fight and loss. This means there will be sadness, fear, anger and disgust. If we remove negative emotions and experiences from our lives, we will be poorer and weaker for having done so.

"Poetry is a great tool for questioning the world," says Sam Illingworth, a poet and a geoscientist who works at the University of Western Australia. Through workshops and a new science-poetry journal, called Consilience, Illingworth is helping scientists to translate their latest results into poems that can attract appreciation from those outside of their immediate scientific field.

Stephany Mazon, a scientist from the University of Helsinki in Finland, joined one of Illingworth's workshops. In the workshop, she was grouped with other scientists and tasked with writing a haiku, a 17-syllable-long poem, which spotlighted water, a fluid that featured in all of the group members' research projects. "It was a lot of fun, and surprisingly easy to write the poem," Mazon says. She plans to continue writing. "We do a disservice (伤害) to ourselves to think that scientists can't be artistic and that art can't be used to communicate scientific ideas," Mazon says.

That viewpoint is echoed by Illingworth, who thinks current science communication initiatives rely too often on public lectures with their hands-off PowerPoint slides. "Actually, when science communication involves writing and sharing poems, it invites a two-way dialogue between experts and nonexperts," he says. Scientist-poet Manjula Silva, an educator at Imperial College London, agrees. Poetry provides a way to translate complex scientific concepts into a language that everyone can understand, Silva says.

Scientists and poets are both trying to understand the world and communicate that understanding with others. The gap between scientists and poets is less than people might think. We're all just people with hopefully really interesting things to say and to share.

Alvin's heart hammered in his chest. Ever since he was a child, he had dreamed of this very scene. He believed this was his childhood wish coming true. And he decided to make Luna's wish come true too. So he posted the Christmas list on his Facebook page, asking for help locating the sender.

Meanwhile, Leticia, the mother of four-year-old Luna, had no idea that such an effort was underway. It had been a hard year for them. On a particularly tough day last December, Leticia told Luna to send her wishes to Santa by balloon. The girl was excited. Leticia helped her write down her wishes, put the note into a Christmas red balloon and took her out to release her wishes on the chilly windy morning.

One day in January, a friend called Leticia, "Someone found Luna's balloon." Her jaw dropped. Then she logged on to Facebook and saw Alvin's post and more netizens trying to help. Leticia was deeply touched and called Alvin. When Alvin told her how much it would mean to him to fulfill the girl' wishes, she agreed to let him meet Luna. Back in Louisiana, Alvin got busy collecting toys from his newfound Facebook community.

On a morning in April, just as chilly and windy as the day when Luna waved goodbye to her balloon, Alvin made a trip to their house. He presented all the gifts, including a puppy. Luna cried with delight. Later, they sat down together to share homemade breakfast. They all felt as if they had known each other forever. Having received so much generosity, Leticia and Luna expressed their gratitude and intended to pay it forward.

One late afternoon, Tina was driving on a highway when a severe (严重的)snowstorm hit without warning before. In a short time, the heavy snow, coupled with the strong wind, turned everything into white and made the road extremely dangerous.

Tina later found out that this kind of storm is called a "Saskatchewan screamer", which comes on extremely fast with high winds. It's really frightening and deadly to be caught in such extreme weather.

Unable to see the road clearly, Tina had to stop her car and call 911. The operator (接线员)told her that phone calls for help kept flooding in and all the rescuers (救援人员)had been called out. She suggested that Tina should wait out the storm in her car rather than risk driving on or going out. She took Tina's information and told her that an officer would call her back. Tina waited anxiously for almost two hours, but nobody called her yet to check in. "The storm showed no sign of stopping. What was worse, it was getting dark. I couldn't see anything outside the car since the snow had covered all the windows. The wind was still howling and the temperature was getting lower and lower in the car. I had no idea whom I could turn to for help," Tina later wrote in a Facebook post. "Alone and cold，I began to panic, worrying about getting hit by an oncoming car, getting buried in a snowbank, having my tailpipe (排气管) blocked by the snow...I was really worried I couldn't ever make it home to my family."

That was when Tina realized that it was no use waiting passively for help. She decided to do something herself. So she took out her cellphone, logged on to the Google Map and determined her location. She found online a neighborhood Facebook group for the area that she was passing through and shared a comment about her trouble with her location marked on the map. Then all she could do next was sitting in the car, praying someone could make a response to her as early as possible.

Fortunately, Tina's request reached 80-year-old retired rescuer Frank.

I wanted to do something special for my 15-year-old son, has always been a perfect boy. He worked all the summer to earn enough money to buy (he) a new bicycle instead of asking for money from me. Then he spent hours and hours on it. I loved my son so much I bought him a pair of sunglasses and gloves. When my son rode the bicycle with them, he looked very cool. He dreamed taking part in a race and winning.

On November 10th, my birthday, when I went to the kitchen to start the milk and bread in the morning, I found beautiful guitar on the table, beside which was a card, (say) "Happy birthday to my wonderful mother. "I was surprised and then began to sob. I remembered once I (joke) to my family that I wanted to learn playing the guitar to make my life colorful. I had forgotten it, but my son remembered. He took it (serious), and bought me one as a birthday gift. When I wondered my son could buy this expensive gift, soon I realized that my son had sold his bicycle (get) me the guitar.
