As we walked about halfway down the hillside，she fell over a stone.I jogged (慢跑) up to where she fell down.Suddenly，I saw a lion making a long deep angry sound about ten feet up on a huge rock watching me.I stood still，holding my breath，wondering what to do.Christina was crying down below.I couldn't shout to her to be quiet，or the lion might attack me. Then，remembering Dad's words，I slowly dropped my backpack and took off my T-shirt.With the pack on one arm and the T-shirt on the other，I spread my arms，trying to look as wide and big as I could.Carefully I moved away down the hillside toward Christina，keeping my eyes on the lion. “Christina，” I called.“Stop crying.Get up slowly and catch my belt. We're going down the hill.There's a lion at the top.” We moved quietly and slowly down the hill.Once back to the forest，with the lion out of view，I removed the sweat from my face with my T-shirt before putting it on，and looked at Christina.Hatless，red eyes，a few small cuts but nothing major.We had hiked for miles before we finally made our way back to our site. Dad saw me first. “Where have you been？”he shouted. “We were so worried，” Mother cried. “Mommy，you didn't have to worry.Sean is really smart，” Christina said.

And if that continues，they'll be extinct in less than a decade.There are a few societies working to prevent this，and now some of them are getting some help from Big Tech. Three such groups have teamed up with Intel to stop poachers (偷猎者).They're doing this by using AI-based cameras in national parks across the globe. The TrailGuard AI camera makes use of Intel's Movidius Myriad 2 VPU processors. “By pairing AI technology with human decision-makers，we can solve some of our greatest challenges，” says Anna Bethke，head of AI for Social Good at Intel.“With TrailGuard AI，Intel's Movidius technology enables the camera to take pictures of suspected poachers and warns park rangers (巡护员) in almost real time，who will then decide the most appropriate response.” Intel claims its system can show the exact position of people and cars among the wildlife with a high degree of accuracy.The first generation of the system involved cameras that were triggered (触发) by movement tracking which would then send photos to the rangers on duty.Inauspiciously，that just sent them a lot of photos they had to review when anything moved in a camera's field of view.However，by adding AI on top of it，the cameras can act as a first-line check and work much better without wasting time. The system is also designed to run at low power，allowing it to function in the wild for up to a year and a half on a single charge.“Edge computing technology has the power to revolutionize the way we understand and protect our wildlife，” said Dr.Fabien Laurier，vice president of National Geographic Labs.“It is really helpful for us to accelerate conservation and work toward our dream of achieving a planet in balance.” 语篇解读　本文是一篇说明文。文章主要说明了人们通过人工智能来帮助阻止偷猎者。 5．What is mainly described in Paragraph 2? A．Why AI-based cameras are popular. B．Why Intel works to prevent poachers. C．How park rangers respond to poachers. D．How TrailGuard AI helps stop poachers. √ 段落大意题。第二段主要描述了人工智能如何帮助阻止偷猎者。故选D。 6．What does the underlined word “Inauspiciously” in Paragraph 3 probably mean? A．Impossibly. B．Unfortunately. C．Immediately. D．Unambiguously. √ 词义猜测题。根据画线词上文“The first generation...the rangers on duty.”以及下文“that just sent them ...a camera's field of view”可知，摄像头会拍摄太多照片，给工作人员带来太多工作，这是不幸的。故画线词意思是“不幸地”。故选B。 7．What does Dr.Fabien Laurier probably think of AI-based cameras? A．He has high hopes for them. B．He is worried about them. C．He has doubts about them. D．He is dissatisfied with them. √ 细节理解题。根据最后一段“Edge computing technology...achieving a planet in balance.”可知，Fabien Laurier博士对人工智能相机寄予厚望。故选A。 8．From which website is the text probably taken? A．www.culturetourism.com. B．www.humanhealthcentre.com. C．www.earthharmonyhabitats.org. D．www.learnkoreanlanguage.com. √ 文章出处题。通读全文，尤其根据第一段“About 35，000 African elephants...help from Big Tech.”可知，文章主要说明了人们通过人工智能来帮助阻止偷猎者。由此可知，这篇文章与地球环境保护有关，可能来自www.earthharmonyhabitats.org。故选C。 Ⅱ.语法填空(每小题1分，共10分) (2025·四川省雅安市高一检测) Bhutan's snow leopard (雪豹) population 1______________ (increase) by 39.5% since 2016，according to a new survey.Findings from over 10，000 camera trap images confirmed the presence of 134 snow leopards in the country，an 2___________ (impress) jump from the baseline of 96 snow leopards in 2016. 3_____ survey showed promising evidence that Bhutan's conservation efforts impact snow leopard populations 4____________ (positive).It involved 310 camera traps across 2.2 million acres of the big cat's habitat. has increased impressive The positively “With less than 3% of the habitat surveyed，there are serious knowledge gaps in the population status of snow leopards，” said Dechen Dorji，Senior Director for Asia，Wildlife Conservation.“A 39.5% increase in Bhutan's snow leopard population is remarkable and calls for the urgent need to 5___________ (strength) the population assessment efforts.These amazing 6_________ (creature) deserve our continued care and protection from illegal hunting，habitat destruction，and conflicts with people.Finding effective co-existence measures between local communities 7______ snow leopards must continue to be at the top of the list.” strengthen creatures and Although the news is uplifting，the species is still listed as endangered by the International Union for Conservation of Nature.It 8___________ (threaten) globally by habitat losses，food shortage，conflicts with humans，and the climate crisis，9__________ (request) continued protection to address these threats，10_______ also affect the other wildlife in their habitat. 语篇解读　本文是一篇说明文。一项新的调查显示，自 2016 年以来，不丹的雪豹数量增加了39.5%。文章主要介绍了不丹为保护雪豹所付出的努力。 is threatened requesting which 考查形容词。此处应用形容词impressive作定语，修饰名词jump，表示“可观的；令人印象深刻的”，故填impressive。 1．答案：has increased 2．答案：impressive 考查动词的时态和主谓一致。此处在句中作谓语，由since 2016可知，句子应用现在完成时，且主语是“Bhutan's snow leopard (雪豹) population”，助动词应用has，故填has increased。 考查副词。此处应用副词positively作状语，修饰动词impact，故填positively。 3．答案：The 4．答案：positively 考查冠词。上文“according to a new survey”第一次提到一项研究，此处是第二次提到，是特指，应用定冠词来修饰，单词位于句首，首字母大写，故填The。 考查名词的单复数。由These可知，此处应用名词复数形式作主语，故填creatures。 5．答案：strengthen 6．答案：creatures 考查动词。动词不定式to后面需要用动词原形，故填strengthen。 考查动词的时态、语态和主谓一致。此处作谓语，it和动词threaten是被动关系，且句子描述一般性事实，应用一般现在时的被动语态，主语为第三人称单数，故填is threatened。 7．答案：and 8．答案：is threatened 考查连词。between...and...为固定搭配，意为“在……与……之间”，故填and。 考查定语从句。空处引导非限制性定语从句，修饰先行词these threats，指物，且关系词在从句中作主语，应用which引导定语从句，故填which。 9．答案：requesting 10．答案：which 考查非谓语动词。此处是非谓语动词作状语，动词request的逻辑主语是前面整个句子，二者之间是主动关系，应用动词-ing形式作状语，故填requesting。 返回 谢 谢 观 看 UNIT 2　WILDLIFE PROTECTION 返回 $
