1．Some young people win distinction （出名） because of their good looks，their dance moves or their singing ability.A much smaller number gain fame because they have done something significant and worthwhile with their abilities.Rishab Jain is among the latter.In 2018 at the age of 13，he developed a way to use artificial intelligence （人工智能） to help pancreatic （胰腺的） cancer patients.Rishab's "Pancreatic Cancer Deep Learning System" won the Discovery Education 3 M Young Scientist Challenge and is 525，000 prize.
   Rishab explains that a family friend died of cancer.Then he learned about how deadly pancreatic cancer is，and that its low survival rate is due to how difficult it is to treat."I'm also into programming，so I was learning about artificial intelligence.I decided to combine the two areas to try to solve a real-world problem using artificial intelligence."
   Rishab has invested his winnings in further research and in his nonprofit （非營(yíng)利的） Samyak Science Society.Samyak helps poor children center the STEM.Rishab is also raising awareness about pancreatic cancer.Many kids would have simply blown their prize money on a fast car or some other shallow things.Rishab has also put some money aside to further his own learning.He is considering becoming a biomedical engineer or a doctor or both.
   How did Rishab become the one that he is？It helped that his father is an engineer.And he has been inspired by his brother and other relatives who work and do research in the medical field.He's seen how STEM jobs have given them "the opportunity to make immediate differences in people's lives".That's an outstanding outlook （見解） for one so young.Rishab is providing his teenage peers with a much-needed model of what kinds of things youth can accomplish.

2．     Only a "cloud" away is how residents at the Dzilam reserve in Mexico think of the distance between Latin America and China，despite their geographical remoteness.
   The "cloud" isn't the one hanging up in the sky.What the residents refer to is in fact cloud technology，which has been applied to wildlife conservation in this Mexican reserve.
In recent years，with cloud technology，technicians and ecologists from China and its trans-Pacific partners have been able to work hand in hand under the Belt and Road Initiative to protect endangered species and their habitats in Mexico.
   Home to many endangered species in Mexico，the Dzilam reserve，known for its biodiversity-rich habitats，has started to witness ecosystem degradation （衰退） over the years due to human activities and climate change.In 2002，the jaguar，the only big cat left in the reserve，was listed as "Near Threatened" on the IUCN Red List.
   Local communities and environmentalists have tried to track the habitat of jaguars，but have found it rather difficult：These animals are often hidden in vast forests，rarely leaving obvious traces，making it hard to observe them under natural conditions.
   To better protect wild animals and biodiversity，the Tech4 Nature Mexico project was launched in the Dzilam reserve.The project collects video data from cameras recording 24 hours a day in the Dzilam reserve to monitor the biodiversity of the area and uses acoustic （聲學(xué)的） technology to understand the existence of species and the health of ecosystems.The research team would use Huawei's Al model to identify the areas where the big cat appeared by identifying sounds，studying their living habits and developing management plans to protect the species.In addition，when a threat is detected，the system immediately sends a real-time alarm with the location to local forest guards through an app for rapid intervention.
   From September 2022 to May 2023，local experts，with the help of Huawei Cloud，have identified 119 species in the Dzilam reserve，including 88 species of birds，22 species of mammals，five species of reptiles and four species of amphibians，of which 34 species are on the IUCN Red List of Threatened Species.They have also spotted at least five jaguars in the reserve.
   Omelia Trejo，a resident of the Dzilam community，said their dream is "protecting jaguars for a lifetime，" but they worried that in the future，children might only see jaguars in photos. "Thanks to this project，our dream has come true."

3．    ON TUESDAY，the Shenzhen team of Blue Sky Rescue，confirmed （確認(rèn)） that two of its members had died trying to rescue 24 tourists.
    According to the official news，it was on Monday that the rescue team received a call from 24 travelers，who were trapped，in a river valley.
    The team responded immediately.However，when they helped the travelers，two team members got trapped by the rising river water.The next day，they were confirmed dead.
    Who can rescue the rescuers？The question aroused a heated discussion among people.Most of them think we would rather such "heroic deeds" were not required.In the past several years，there have been many cases in which travelers，ignoring the signs saying certain areas are dangerous and off-limits （禁止進(jìn)入的），ended up needing to be rescued.By so doing，they put not only their own lives at risk but also the lives of those who go to their aid.
    Although the majority of travelers behave properly，some attempt challenging tasks that are obviously beyond their abilities.
    The law has already made it clear that if a traveler or group gets into difficulties when entering unauthorized （未經(jīng)許可的） regions，they must bear the costs of the rescue.The rules need strengthening to deter travelers from putting their own lives and the lives of others at risk.

A．24.

C．42.
D．26.
（2）What happened to the two rescue workers？
