Without these trees, koalas cannot survive. In recent years, koalas have faced serious threats. They are hunted by other animals, suffer from diseases, and are often hit by cars. Wildfires have destroyed large areas of forest, and humans continue to cut down eucalyptus trees for wood. As a result, koala numbers have fallen sharply. In the Australian state of New South Wales (NSW), koalas are now considered endangered, meaning they are at risk of disappearing forever. The Australian government has warned that if no action is taken, this could happen by 2050. However, there is some good news. The Australian government has announced the creation of a new national park designed to protect koalas. The Great Koala National Park (GKNP) will cover 4,760 square kilometres, making it one of the largest parks in NSW. The park will connect with existing national parks to create a much larger protected area. For many years, people have worked to protect koalas, mainly by protecting eucalyptus trees that provide food and shelter. Their efforts led to the idea of creating a national park dedicated to the koala.  The plan became a greater need after wildfires killed thousands of koalas in 2019 and 2020. In February 2022, koalas were officially listed as endangered. In September 2025, the government said that $146 million would be set aside to create the park and that tree-cutting in the area should stop. This move is expected to protect about one-fifth of the remaining koalas in NSW. Wildlife groups welcomed the decision but pointed out that habitat destruction remains the main threat. The new park is seen as only a first step towards protecting these endangered and well-known animals and ensuring their future survival. (　)1.What situation about koalas is described in the first two paragraphs? A.Growing risks to their survival. B.Reduced threats to their survival. C.Stable numbers in their population. D.Improved conditions in their forests. (　)2.The underlined phrase “dedicated to” in Paragraph 4 is closest in meaning to 　　　　.  A.far from　　　　B.harmful to C.crowded with D.designed for (　)3.What do wildlife groups probably think about the new park? A.It is just a first step. B.It is mostly for show. C.It is too small to matter. D.It is a complete solution. (　)4.What is the author’s main purpose in writing the passage? A.To address environmental problems. B.To discuss threats to koalas and solutions. C.To explain why koalas are endangered. D.To describe the history of national parks. ●Ⅳ 阅读七选五(每小题2.5分,满分12.5分) [2026·广东广州二中高一期末] The evolutionary choice and survival crisis of African elephants The world’s African elephants are in serious danger. 1.　　　　 And if we do nothing to put an end to the illegal ivory trade, elephants will be extinct from the wild within the next 20 years.  Many believe that an illegal hunter could get ivory without killing the elephant—this is not true. 2.　　　　 And the rest lies beneath the surface like an iceberg in water. The tusk (象牙) is not just bone but rather it is alive, filled with nerves and blood vessels (血管) and when broken off, the tusks would likely become infected and lead to a slow and painful death.  However, there is a new form of hope rising from nature itself. African elephants are being born without the tusks that illegal hunters have hunted for decades. But why is the largest land mammal on Earth now being born tuskless? 3.　　　　　  Is such change beneficial to elephants’ survival in the long term? As we know, elephant tusks are not just glorious-looking. 4.　　　　 Therefore scientists are working to track the newly tuskless among them, to see how this unfortunate adaptation affects the species.  Ivory hunters are not the only danger faced by elephants today. More support is needed than ever to create a safe world where elephants can live together with humans happily, tusks and all. 5.　　　  A.Action should be taken to protect animals in the world. B.Only two-thirds of an elephant’s tusks stick out of their mouth. C.They also have important uses such as self-defense and digging. D.It is estimated that one is killed every 15 minutes for its ivory. E.That’s because elephants without tusks have a better chance of surviving. F.After centuries of being hunted by humans, many African elephants are tuskless. G.And it’s in our power to make this happen by cutting demand and raising awareness. ●Ⅴ 完形填空(每小题1分,满分15分) [2026·云南曲靖高一期末] My love of nature started with a book called The Jungle Mystery when I was a kid.
