This was certainly true for a dog named Lucky in a small town in China. Lucky lived with the Chen family. One summer night, everyone was sleeping soundly. Suddenly, Lucky started barking loudly and scratching at the bedroom doors. He wouldn't stop. Mr. Chen woke up, feeling annoyed. "Quiet, Lucky! Go to sleep!" he shouted. But Lucky kept barking and running to the front door. Then Mrs. Chen noticed something strange. "The floor feels like it's moving," she said. Just then, the bed started shaking. "Earthquake!" Mr. Chen shouted. He woke up his children, and they ran outside. Lucky ran with them. Outside, they joined other neighbors who had also run out of their homes. The shaking continued for about 30 seconds. When it stopped, they saw that some houses had cracks in the walls. But everyone in their neighborhood was safe. Later, they learned that the earthquake was magnitude (震级) 4.8. No one in their town died, and people said it was because of warnings from animals like Lucky. From that day on, the Chen family treated Lucky like a hero. "He saved our lives," Mr. Chen said. "If he hadn't woken us up, we might still be inside when the earthquake hit." 根据短文内容，选择最佳答案。 21.

Scientists have long believed that lightning is always bad for trees. But a 2025 study from the University of Birmingham has found something surprising. The research team studied trees in a Panamanian rainforest. They found that some trees have a special ability to survive lightning strikes. One tree even grew new branches from its damaged top after being hit. This was the first time scientists had seen such a strong recovery (恢复). The study showed that some tropical trees have a natural protection against lightning. Their bark (树皮) is thicker and contains special chemicals. These chemicals help reduce the damage when lightning strikes. Why does this matter? Every year, about 100 lightning bolts (闪电) hit each square kilometer of some rainforests. Understanding how these trees survive can help scientists develop better lightning protection for buildings and power lines. It may also help us understand how rainforests will change with more storms in the future. Dr. Evan Gora, who led the study, said in an interview, "We used to think lightning only killed trees. Now we know that some trees are much stronger than we thought. Nature still has many secrets to share with us." 根据短文内容，选择最佳答案。 26. What did the 2025 study from the University of Birmingham discover? A. Lightning is always bad for trees. B. Some trees can survive lightning strikes. C. Rainforests have fewer lightning strikes. D. Trees grow faster after being hit by lightning. 27. How do some tropical trees protect themselves from lightning? A. They have very deep roots. B. They grow very tall. C. They have thicker bark and special chemicals. D. They move away from lightning. 28. What happened to one tree after it was hit by lightning? A. It died immediately. B. It grew new branches. C. It changed color. D. It fell to the ground. 29. How can this discovery help humans? A. It can help develop better lightning protection. B. It can help grow more trees. C. It can help stop lightning. D. It can help build taller buildings. 30. What does Dr. Evan Gora think about the discovery? A. He thinks lightning is very dangerous. B. He thinks the study was a failure. C. He thinks trees should be protected. D. He thinks nature still has many secrets. C Surviving the Storm: One Family's Story When Hurricane Melissa hit Jamaica in October 2025, it was the strongest storm to reach the island in years. Winds reached 260 kilometers per hour. The hurricane destroyed thousands of homes and left many people homeless. Antwane, a 15-year-old boy from a small fishing village, still remembers that day clearly. "I was helping my grandmother prepare dinner when my father ran inside," Antwane told UNICEF reporters in December 2025. "He shouted, 'A big storm is coming! We have to leave now!'" The family gathered what they could — some food, water, and important papers — and rushed to a nearby shelter (避难所). The shelter was a solid building that had been built after a previous hurricane. It was crowded. Antwane counted over 100 people in the same room. "That night was the longest night of my life," Antwane said. "We could hear the wind howling (呼啸) outside. It sounded like a monster. I was holding my grandmother's hand the whole time." When they came out the next morning, their village was destroyed. Many houses were gone. Trees had fallen everywhere. But Antwane's family was safe. "Losing our home was hard," Antwane said. "But we still have each other. And people from all over the world sent help. We will rebuild." Thanks to early warnings and emergency shelters, no one in Antwane's village lost their life. The experience taught him the importance of being prepared. 根据短文内容，选择最佳答案。 31.

According to a 2025 report by the World Meteorological Organization, hurricanes and typhoons are becoming stronger and more dangerous. 37 These storms now carry more rain and have stronger winds. This is because warmer oceans give storms more energy. Scientists have been studying this problem for years. 38 For example, Hurricane Melissa in 2025 was one of the strongest storms ever recorded in that area. 39 They are building stronger sea walls. They are creating better warning systems. They are planting more trees along coastlines to reduce flooding (洪水). Dr. Maria Santos, a climate scientist, said in a 2025 interview, "We cannot stop climate change overnight. 40 Every small action counts." ( A. Their 2025 study shows that storm speeds have increased by 20% in the past 30 years . B. The storm lasted for over 10 hours. C. It is also making natural disasters worse. D. But we can prepare for what is coming. E. People around the world are taking action to protect their cities. F. They now develop faster and cause more damage. ) 四、词汇运用（共15小题；每小题1分，满分15分） A) 根据句意和汉语提示，写出单词的正确形式。（每小题1分，满分8分） 41. A terrible _________ (地震) hit the small town last night. 42.
