第二节 (满分 25分) 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 Our monthly Community Day is my favorite — a get-together where neighbors come to bond through fun activities and strengthen our community spirit. But I was certainly nervous that Sunday two years ago. I had invited my new neighbor Chelsy — who had just moved in and was going through a tough time — and her 10-year-old daughter, Olivia, to attend the event. I hoped it might provide her with a sense of community during a difficult season. That Sunday morning, our community was hosting a pancake breakfast before the activities to welcome any newcomers, and I was eager to make sure everything went just right. Remembering the long lines from the previous breakfast, I had purposely told Chelsy to arrive fifteen minutes late so we could skip the waiting. We were able to walk right up to the breakfast buffet, but my eight-year-old daughter Evelyn whispered, “They're out of French toast.” Even worse, we had to wait several minutes for the next batch of pancakes. Finally, as we loaded our plates, I realized all the seats had already been taken. “Here, take our seats. We're done,” said a gentleman who must have seen the desperation in my eyes. My anxiety eased a little. I silently hoped our guests' experience would go smoothly from then on. But it wasn't to be. Noticing that our guests didn't have anything to drink, I got up to fetch water, but it took a while to find a pitcher (水壶). When I returned to our table, everyone had finished eating. I was so disappointed that I'd missed my opportunity to talk with Chelsy and her daughter and get to know each other better. Later, it was almost time for the activities to start, so we headed to the hall to check in. “Why is the line so long today?” I wondered. That was when I remembered receiving an email warning about delays due to the new check-in system. After twenty minutes, we finally reached the front, only to be asked to wait again — this time because our guests' first visit required extra time to enter their information. 注意: (1) 续写词数应为 150 左右; (2) 请按如下格式在答题卡的相应位置作答。 Finally, we stepped inside and my anxiety hit its peak. ____ Chelsy shook her head slightly and smiled. ____

As a kid, Jorg Massen would watch birds dive and circle overhead and wonder whether they were doing it for enjoyment. Massen, now a behavioral biologist at Utrecht University, was finally able to put that question to the test thanks to a nearby bird park. For several months each year the birds at Avifauna Bird Park are free to leave their cages at certain times every day. When the gates open, each bird decides for itself: fly out into the open sky or stay home. They get no punishment or reward either way. Among these birds were 17 pink-and-gray Galah Cockatoos (鹦鹉) that, in the wild, fly long distances to find seeds. They chose to fly for almost every 20-minute period offered, Massen reported. "Their consistent choice to fly is in line with the idea that the birds found flight rewarding," says Michael Mendl, an animal behavior researcher. The only exception was a pair of birds that skipped flying once, on a day when they had just been given new nest boxes. Massen says, "they had other activities to attend to, which are also considered joyful." After flight sessions, the Galahs searched for food, scratched and raised their crests (羽冠) more — behaviors interpreted as signs of "positive excitement resulting from free flight." And in a test designed to measure optimism, the Galahs grew more hopeful of finding their favorite treat (a walnut) when they'd had several days of free flight and more pessimistic after several days of being grounded. Animal-cognition scientists used to be hesitant to judge whether animals have conscious experiences, but researchers have become increasingly open to accepting the idea. If birds are capable of conscious experience, Mendl says, "the findings would indeed suggest that the birds enjoyed flying." For Galahs, Massen says, flight appears to be a behavior they're naturally driven to perform. Massen sees his study as part of a broader shift in animal-welfare science away from only preventing suffering and toward designing environments that let animals express the natural behaviors that seem to make them feel good. 32. What did the Galahs do during the experiment? A. They flew mainly to look for seeds. B. They waited for a reward before flying. C. They rarely turned down the chance to fly. D. They only flew when the keepers gave them food. 33. What did the test in paragraph 5 show? A. The birds grew tired of flying after many sessions. B. The birds expected fewer treats after several flights. C. The birds lost interest in their walnut treats over time. D. Flying lifted their spirits while staying in lowered them. 34. What is the significance of the study according to Massen? A. It shows a return to studying animals in the wild. B. It shows a focus on preventing animals' suffering. C. It causes a debate over whether animals belong in cages. D. It signals a move toward letting animals behave naturally. 35. Which of the following is the best title? A. Why Do Birds Fly? B. What Do Birds Want? C. Do Birds Enjoy Flying? D. Do Birds Have Consciousness?

At the 20th Asian Games Aichi-Nagoya 2026, 17-year-old Chen Yujie of China made history. On September 25, she claimed the women's 100-meter gold medal in 11.06 seconds, setting a new Games record, beating the previous mark of 11.15 seconds set by Sri Lanka's Susanthika Jayasinghe in 2002 — a record that had stood for 24 years. The road to victory was far from smooth. In the semi-finals, Singapore's two-time Olympian Shanti Pereira clocked 11.28 seconds and became the clear favorite. Chen clocked 11.41 seconds — a solid result, though not eye-catching — to secure her place in the final. Chen later admitted she felt heavy pressure ahead of her first Asian Games final. "On the training track, my legs shook. I was afraid of a false start," she recalled. Rather than submitting to nervousness, she kept repeating to herself, "Stay calm, avoid mistakes, and run cleanly." When the starting gun went off, Chen found another gear. She turned in a brilliant final run and crossed the finish line first. Pereira took silver with a season-best 11.21 seconds, while Bahrain's Edidiong Odiong earned bronze in 11.33 seconds. For Chen, this gold serves as an early, meaningful birthday gift. She will turn 18 this December — the legal age of adulthood in China. When asked how fast she believes she can go in the years ahead, she just replied: "I have no limits." Pereira spoke highly of the rising Chinese sprinter. She said she was excited to see what Chen would do and believed Chen would keep breaking records. This remarkable win builds on Chen's earlier achievement: she won the women's 200-meter title at the 2025 Asian Athletics Championships, where she also finished ahead of Pereira. Now holding her first Asian Games gold, the teenager has set her sights higher. "I hope to show my strength at the World Championships and the Olympics. I want to leave my mark on Chinese and Asian women's sprinting," Chen shared. 24. What do we know about Chen Yujie from this article? A. She broke a 24-year-old Asian Games record. B. She made it to the final with an extraordinary result. C. She beat Shanti Pereira by 0.09 seconds in the final. D. She won her Asian Games gold medal at the age of 18. 25. What does the underlined phrase "found another gear" in Paragraph 4 mean? A. Realized her true personal limit. B. Entered a more powerful state. C. Changed her usual way of running. D. Discovered new sports equipment. 26. Why does the writer mention Chen's success at the 2025 Asian Athletics Championships? A. To stress rules vary in different competitions. B. To show her Asian Games victory was no accident. C. To explain why she felt great pressure before the final. D. To prove she once broke a Games record at that competition. 27. What message does the author want to convey? A. Young athletes can break records as long as they keep calm. B. Top-level runners often set higher goals for their own future. C. Real courage is moving forward bravely when you feel afraid. D. Constant hard work is the only secret to becoming a great athlete.

阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 Grandpa handed Toby a small whistle (哨子) carved out of thick animal bone. Its surface was worn smooth by years of use. “This is a winter whistle,” Grandpa explained. “If you are ever lost in the woods when it snows, blow this. The sound carries far across snow-covered ground. We will hear you and come find you.” Toby slipped it deep inside his winter-coat pocket, “I’m 12, and I no longer need to call for help!” To him, blowing the whistle would mean admitting he was not brave enough. That weekend, Toby went snow-trekking (雪地徒步) in the nearby forest with his best friend Jax. But an argument broke out between them over a silly game. Toby stormed off in anger, leaving Jax behind. He told himself he did not need anyone’s company. He would explore deeper into the woods alone to prove how tough he was. But the sun began to set. Grey clouds rolled in unexpectedly. A bitter winter wind sprang up. Snow began to fall in thick, swirling flakes. The gentle afternoon snow quickly turned into a snowstorm. Visibility dropped sharply. Toby could no longer tell which path led back home. He was lost. Cold bit through his gloves and his winter jacket. His cheeks and nose ached from the bitter wind. Panic rose inside his chest. He pulled his hands out of his gloves and fumbled (摸索) inside his coat pocket. His fingers closed around the hard shape of Grandpa’s whistle. It was right there. But shame washed over him. He had run away after the fight. If he blew the whistle, Grandpa and Jax would know he had acted stupidly. They would laugh at him for getting lost. Pride held him back. He stuffed the whistle back into his pocket and told himself he could find the way home by himself. He struggled forward through the heavy snow. The wind howled, blowing snow into his eyes. The temperature kept dropping. Still, the whistle stayed safely hidden in his pocket. As it was getting dark in the snowy woods, Toby felt close to passing out from the cold. He had to hide behind a large pine tree for shelter. 注意: 1. 续写词数应为 150 左右; 2. 请按如下格式在答题卡的相应位置作答。 Inside his pocket, the bone whistle pressed against his hand. The sound of the whistle drew anxious Grandpa and Jax over.
