This change directly affects the number of its main predator, the lynx (猞猁). This interaction is a classic example studied in ecology. However, scientists are now "alarmed" to see these natural cycles becoming less predictable due to climate change. Warmer winters with less snow are a problem for the snowshoe hare, whose white winter coat makes it easy to spot against the brown, snowless ground. It’s harder for them to hide, and more of them are likely to "lose their lives". Meanwhile, halfway across the world, in a "nature reserve" in China, a different kind of guardian is at work. The "red-crowned crane" is not only a rare and beautiful bird but also plays a crucial role in its ecosystem. It helps control insect populations and spreads seeds. However, these cranes are "under threat". The wetlands they live in are being used for farming and building. To "protect" them, conservationists work "day and night". They "make use of" technology like drones (无人机) to watch the cranes without disturbing them. They also work with local farmers to create a safe environment. The situation of the polar bear is even more serious. As sea ice melts, polar bears have to swim longer distances to find food, which uses up their energy. Sometimes, they are "forced" to come near towns to look for food, which is dangerous for both bears and people. "The progress in saving them is slow," says a researcher. "It requires a global effort." What all these stories show is that every animal, big or small, is part of a complex web. Protecting them is not just an act of kindness; it is necessary for keeping the balance of nature. The "direction" for the future is clear: we must act now. 26. What is the main reason the snowshoe hare is facing more danger now? A. The increasing number of lynxes. B. The loss of their natural food. C. Warmer winters with less snow cover. D. Too many human hunters. 27. According to the passage, how do the red-crowned cranes help their ecosystem? A. By making the wetlands more beautiful. B. By controlling insects and spreading seeds. C. By attracting tourists to nature reserves. D. By working with local farmers. 28. Why are polar bears sometimes “forced” to come near human towns? A. Because they are curious about human life. B. Because the sea ice is melting and they need to find food. C. Because they have lost their way in the vast ocean. D. Because people in towns feed them. 29. What does the underlined word "progress" most likely mean? A. Movement forward. B. A difficult situation. C. A research project. D. A new law. 30. What is the main purpose of this passage? A. To introduce three interesting animals to the readers. B. To explain how drones are used in animal protection. C. To show the challenges some animals face and the need to protect them. D. To compare the living conditions of animals in Canada and China. （二）首字母填空（10小题，每小题1分，共10分） 根据短文内容和首字母提示，写出所缺单词，使短文完整、通顺。 A Call for Help One day, a man named Peter found a s__31__ bird with a broken wing near his house.
