习题讲评(一)　主题阅读训练 A (2025·秦皇岛模拟)Scientists are worried about the future of the axolotl (蝾螈), an unusual Mexican salamander (蜥蜴), and they're asking for help. A new program lets people “adopt” an axolotl to raise money to support efforts to save the endangered animal. If an axolotl loses a leg, or even part of its heart, brain, or lungs, it can regrow them. Scientists have long been interested in this. Some people think the information could help solve some human medical problems. The Mexican axolotl is only found naturally in Lake Xochimilco near Mexico City. This is not a big and open lake, but a collection of canals and smaller bodies of water. Sadly, axolotls are in trouble. The number of axolotls in Xochimilco has dropped 99.5% in less than 20 years. Scientists used to find thousands of axolotls in a fairly small area. Now, they're only finding dozens. There are a number of reasons for the drop in axolotls. One is that the water in the canals has become more and more polluted. Another is that there are invasive fish in the lake which are eating the axolotl's food and even their babies. Scientists at Mexico's National Autonomous University (UNAM) have been working for years to try to protect the axolotls. Last year, the UNAM scientists started a program they called AdoptAxolotl. They asked people to donate money to help pay for efforts to save the axolotl. The program was a big hit, and raised more than $26,000. The money was used to help clean up some of Xochimilco's canals and for a program to raise axolotls in a safe environment. This year, the scientists are trying AdoptAxolotl again. The program offers several ways for people to support axolotls. For $30, you can virtually “adopt” one of the animals for a month. Smaller donations can help pay for food for an axolotl. Larger donations are aimed at improving areas where axolotls live, and include a visit to the protected area where UNAM is raising axolotls. 语篇解读：本文是一篇说明文。文章主要介绍了墨西哥蝾螈面临着严峻的生存危机，科学家们正致力于拯救这种濒危动物。 1．What have the scientists had an interest in?

In the 1950s, the boom in package tourism showed promise as a new cash crop. But while the Canary Islands had the sunshine, warm climate and ease of access from Europe needed for this new industry, they were missing a vital element picture postcard sandy beaches. So the developers on Tenerife in the Canary Islands constructed a breakwater (防波堤) over half a mile long. And then, from the Western Sahara on Africa's northwest coast, they shipped in 270,000 tons of sand. By 1973, the project was complete. As anticipated, tourists arrived. Along the engineered beach, rows and rows of tourists relax on beach chairs under umbrellas or walk across soft sand to cool down in the water. Unanticipated was what their presence gave to one of the world's most endangered fish species, angel sharks — visibility. The gentle wind creates tiny waves on the water's surface, a magical cover for what lies beneath — an angel shark nursery. Female angel sharks regularly migrate to these ideally sheltered waters to give birth to pups (幼崽), who remain in the shallows for about a year. Feeding on small fishes, they grow to around the same length as a newborn human baby. Surveys have shown that other beaches in the Canary Islands are also potential nursery sites. Interestingly, most of them have been remade to make them more attractive to people. Playa Chica has another long sweep of imported sand. It's an attraction for divers as well as angel sharks, so the number of sightings of mature angel sharks of this shoreline is one of highest in the islands. Normally, massive, environmentally disruptive projects are bad for wildlife.But what's clear is that after the breakwater was built and the sand arrived, people followed, and in the calm, shallow waters they began to see baby angel sharks. And unlike how many an association between humans and wildlife ends-in conflict and dead animals, this time it led to conservation. 语篇解读：本文是一篇说明文。文章主要介绍了加那利群岛通过人造沙海滩吸引旅游的同时，意外地为濒危物种天使鲨提供了理想的繁殖地，从而促进了对该物种的保护。原本可能对环境产生负面影响的人工改造工程，在此案例中却意外成了野生动物保护的契机，展现了人与自然可以和谐共存的可能性。 5．Why did the developers on Tenerife carry out the project?

Hummingbirds are a very important part of Mexico's ecosystem, but because of the ever-expanding urban landscape, they face all sorts of serious threats. That's where 73-year-old Catia comes in. As a self-taught hummingbird caretaker, she devotes most of her free time and resources to nursing the tiny birds back to health. She has been doing it for over a decade and her home in Mexico City has become known as a hummingbird hospital. Catia's story as a hummingbird nurse began in 2011, at a very difficult moment in her life. She had lost her husband two years prior and she herself was battling cancer. She was walking on the street one day when she noticed a hummingbird that had suffered a serious eye injury. The kindhearted woman took it home, but she knew nothing about taking care of a bird, let alone such a tiny one. However, a veterinarian (兽医) friend encouraged her to look after the hummingbird, and that led to a life devoted to rescuing hundreds of tiny birds. “It wrote me a new life，” Catia recently said about Gucci, the first hummingbird she ever cared for. Catia managed to nurse Gucci back to health, but she claims it was the tiny bird that saved her. She had sold her five high-end boutiques (精品店) in the city to focus on her battle with cancer and had fallen into a depression, but the hummingbird managed to pull her out of the sadness and loneliness that had taken over her life. And it was only the beginning. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 Word of her success spread among Catia's friends, and before long some of them began bringing her injured and abandoned hummingbirds. __________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ In order to raise awareness of the difficulty of hummingbirds in Mexico, Catia started posting videos of the patients on social media and many of them spread quickly.　__________________ ________________________________________________________________________________________________________________________________________________________________ 参考范文： Word of her success spread among Catia's friends, and before long some of them began bringing her injured and abandoned hummingbirds. She never turned them away. Some of them were just babies, while others had physical injuries or had suffered poisoning. She needed to study the birds and their habits in order to better take care of them, and after many years of experience, the 73-year-old woman is considered an expert on hummingbirds and she has been invited to speak at several events. In order to raise awareness of the difficulty of hummingbirds in Mexico, Catia started posting videos of the patients on social media and many of them spread quickly. That's when the demand for her nursing services really blew up. She has cared for hundreds of hummingbirds in her career. Together with her partners, she spends pretty much all her time looking after the tiny birds. After nursing the birds back to health, Catia releases them in a wooded area on the south side of Mexico City. The ones that are beyond saving are cared for until their last moments and then buried near her building. 7 / 7 学科网（北京）股份有限公司 $$
