B3 U1 Nature in the balance 【救助小天鹅】 ★名校真题【2026届河南南阳高一期末】 16-year-old Leo had a deep passion for visiting the wetland near his hometown every weekend. It was his secret escape, a place overgrown with weeds, with fresh water nearby, where the air smelled sweet and the sound of birdsong enveloped him like a warm blanket. He always carried a small bag of grain in his pocket, not just to feed the swans(天鹅), but to watch the way their graceful necks curved as they ate. Last Sunday, however, a sense of unease swept over him — something felt out of the ordinary. As Leo walked along the wetland path, he called softly for his favorite swan family: a mother swan and her three babies. Normally, the mother would lift her head at the sound of his voice and walk quickly toward him, her lovely babies following closely behind. But that day, only two babies appeared. His heart dropped instantly when he spotted a white shape lying beside the weeds, without a move. Not wanting to waste a single second, Leo rushed over. There, half-hidden by the grass, he found the missing baby swan: it let out faint, weak calls and its left wing was broken. Carefully cupping the tiny bird in his hands, he gently wrapped it in his jacket to protect it from the cold. “Don’t worry, little one,” he whispered softly, his voice warm with care. “I won’t let anything happen to you.” Leo didn’t hesitate — he held the baby swan close to his chest and hurried toward home to seek help from his vet (兽医) mother. His legs ached as he ran, but he didn’t slow down; his mind raced with plans. The quiet wetland, once a place of calm where he’d sat for hours watching the swans, now felt cold and lifeless, the air thick with the pressure of a race against time. But as he felt the baby swan’s soft heartbeat close to him, stable yet weak, he was determined to give it a fighting chance, no matter what. 注意：1.续写词数应为150个左右；2.请按如下格式在答题纸的相应位置作答。 Upon arrival, he told his mother what was happening. They cleaned the baby swan’s wound, applied a bandage, and made a cozy bed with old towels. The next week, Leo took on the task of feeding it fish and changing its bandage. Slowly but surely, the little one grew strong enough to flap its wings. One afternoon, Leo carried the baby swan back to the wetland. The moment he set it down, the mother swan glided over, brushing the baby swan tenderly with her beak. To his delight, the other baby swans joined in the greeting, forming a small circle around their sibling as if welcoming it home. But Leo knew this was not enough and that he needed to do more with others. He shared the swan’s story with his classmates, and together, they decided to set up a “Wetland Guardians” group. They put up posters to remind visitors not to litter and partnered with local environmental experts to build special feeding stations for the wetland birds. Now, every weekend, Leo and his friends visit the wetland to check on the birds. The once-injured swan has grown into a graceful, beautiful one, and it still swims over to greet Leo whenever he arrives — a gentle reminder that even the smallest act of kindness can help nature thrive. 【导语】本文以人物为线索展开，主要讲述了16岁的Leo热爱家乡附近的湿地，常去喂天鹅。某周日他发现一只小天鹅翅膀折断，便带回家让当兽医的母亲救治。经过悉心照料，小天鹅康复后被放回湿地，与家人团聚的故事。 【详解】 1.段落续写： ①由第一段首句内容“一到家，他就把发生的事情告诉了母亲。”可知，第一段可描写Leo和母亲一起救治小天鹅，以及小天鹅康复后被放回湿地与家人团聚的情景。 ②由第二段首句内容“但Leo知道这还不够，他需要和别人一起做更多的事情。”可知，第二段可描写Leo意识到保护湿地的重要性，与同学们一起成立“湿地守护者”组织，为保护湿地和鸟类做出更多努力。 2.续写线索：到家告知母亲——救治小天鹅——小天鹅康复——回到湿地——与家人团聚意识到保护湿地的重要性——成立“湿地守护者”——为保护湿地和鸟类做出努力——小天鹅长大——成为Leo善意的提醒 ★话题词汇 行为类 ①包扎：apply a bandage/wrap up/dress the wound ②喂养：feed /raise/nourish ③建立组织：set up a group/establish an organization/found a team 情绪类 ①令某人高兴的是：to one’s delight/to one’s amusement ②温柔地：tenderly/gently/softly ★话题句式 【高分句型1】The moment he set it down, the mother swan glided over, brushing the baby swan tenderly with her beak.(运用了the moment引导的时间状语从句) 【高分句型2】The once-injured swan has grown into a graceful, beautiful one, and it still swims over to greet Leo whenever he arrives — a gentle reminder that even the smallest act of kindness can help nature thrive.(运用了whenever引导的时间状语从句) 【救助流浪小狗】 ★名校真题【2026届山东高一期末】 It was a cold December afternoon. Lily, a 16-year-old high school student, was walking home from school alone. The wind was howling, and snowflakes were dancing in the air, covering the roads and trees with a thick white blanket. She pulled her coat tightly around herself and quickened her steps, anxious to get back to the warmth of her home. As she passed an old alley(小巷) near her neighborhood, she heard a faint whimpering sound. Curious but a little frightened, Lily hesitated(犹豫) for a moment. The sound was soft and weak, like that of a small animal in trouble. “Should I check it out?” she thought to herself. Her parents had always told her not to talk to strangers or go into dark alleys, but the pitiful sound touched her heart. She took a deep breath and walked slowly into the alley. The snow was deeper here, and the wind seemed to blow even harder. After walking a few steps, she found a small, shaking puppy huddled behind a pile of old boxes. Its fur was covered with snow and dirt, and its eyes were filled with fear and helplessness. Lily’s heart melted immediately. She knelt down(跪) gently and reached out her hands. The puppy looked at her cautiously, then slowly moved closer and licked her hands. Lily knew she couldn’t leave the poor puppy alone in the cold. But she also worried: her mother showed no interest in furry animals, and her father was always busy with work. Would her family agree to keep it? With a determined look, she wrapped (包,裹) the puppy in her scarf and held it tightly in her arms. She hurried home, hoping that her parents would understand her decision. 注意：1. 续写词数应为150左右; 2. 续写部分分为两段，每段的开头语已为你写好。 As soon as Lily got home, her mother’s eyes fell on the small puppy. “Lily, what’s this?” her mother asked, a little surprised. Lily hugged the puppy tightly, explaining how she found it shivering in the cold alley, helpless and frightened. She begged her mother to let them keep it, promising to take full responsibility for feeding and cleaning it. Her mother softened when she saw the puppy’s innocent eyes and Lily’s determined look. Just then, her father came home and, after hearing the story, smiled and nodded. The puppy licked their hands gently, as if expressing thanks. A week later, the once-frightened puppy had become an important part of the family. It was no longer shy and would run to greet Lily and her parents when they got home. Lily named it Snowy for its white fur after being cleaned. She fed it every morning and played with it after school, while her mother even prepared a soft bed for it. Her father, though busy, would take Snowy for a walk on weekends. Snowy brought endless joy to the family, and Lily knew her kindness had given the little puppy a warm home and themselves a precious companion. 【导语】本文以流浪小狗为线索，讲述了寒冷的十二月下午，莉莉放学独自回家，路过小巷时听到微弱的呜咽声，不顾父母的叮嘱走进小巷，发现一只浑身是雪、瑟瑟发抖的流浪小狗，心生怜悯将其用围巾裹起抱回家，内心既心疼小狗又担心父母不同意收养它的故事。 【详解】 1. 段落续写： ① 由第一段首句“莉莉一到家，妈妈的目光就落在了那只小狗身上。”可知，本段可描写莉莉劝说父母收养小狗的过程。 ② 由第二段首句“一周后，这只曾经惊恐的小狗已经成为了家庭中重要的一员。”可知，本段可描写小狗融入家庭的温暖场景。 2. 续写线索：莉莉带小狗回家，妈妈发现后惊讶——莉莉解释经过、恳求父母、承诺负责——妈妈心软、爸爸同意收养——一周后小狗变得活泼——莉莉照料小狗，父母主动关爱——小狗给家庭带来欢乐 ★话题词汇 行为类 ①解释：explain/clarify ②恳求：beg/plead ③照料：feed/take care of 情感类 ①善良：kindness/goodness ②喜悦：joy/happiness ★话题句式 【高分句型1】Lily hugged the puppy tightly, explaining how she found it shivering in the cold alley, helpless and frightened.(运用现在分词explaining作伴随状语) 【高分句型2】Her mother softened when she saw the puppy’s innocent eyes and Lily’s determined look.(运用when引导的时间状语从从句) 【救助野生小象】 ★名校真题【2026届湖北武汉高一期末】 A Midnight Rescue It was not uncommon to carry out tasks at night as rescuers. Harry and David were informed of their task when it was nearly midnight. It was urgent so there was no time to hesitate. They headed into the forest. The forest was black and silent. A little way into it they reached a fork(岔路) in the earth path. Harry and David took the left path. They walked in silence, their eyes on the ground, watching out for the traps like big pits(坑) set by the illegal hunters. Every now and then a ray of moonlight through the branches above lit a spot of bright red blood on the fallen leaves. David saw that Harry looked very worried, asking, “Could Unicorn be hurt that badly?” Harry answered, “If we can’t find it as soon as possible, it doesn’t stand much chance to survive.” Of course, Unicorn was not the animal in fairy tales but the nickname of a 3-year-old elephant, the last wild elephant in this forest. The nickname was given by the biodiversity rescuers who were protecting every member in this forest. They knew Unicorn was obedient(顺从的) and not afraid of human beings. “Without it, the forest was not complete. Those illegal hunters should be thrown into prison. “ Harry thought, carrying his first aid kit (急救箱) on his back and walking forward with his flashlight. It seemed that thick fog would come at any time, which would increase the danger. Harry hurried into the heart of the forest with David. They walked for nearly half an hour, deeper and deeper. There were blood splashes on the roots of a tree, as though the poor creature had been struggling around in pain close by. “We must hurry up”, said Harry. 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。 However, it was really not easy for them to find it. Thick fog came, covering almost everything. They had to bend down to search for clues like blood splashes or footprints, which made them walk more slowly, ears sharper than usual. Suddenly, painful roars came to the rescuers and in front of them lay the young elephant. “Look! Unicorn! “Harry rushed forward, cried excitedly, and gently touched the trembling creature. His heart dropped a beat at the sight of the exhausted elephant, with a wound on its left front leg bleeding badly. Without delay, Harry knelt down to do first aid on its wound. Fortunately, everything needed was available in the first aid kit. Calmly and skillfully, Harry conducted an operation on Unicorn immediately, and it seemed more obedient than before. Therefore, it didn’t take much time for Harry to stop the bleeding as an experienced rescuer. And after a while, Unicorn was able to stand up and walked away. It was rescued! Waving goodbye to it, Harry and David felt a heavy burden lifted. At this moment, the whole forest woke up, the moonlight fading while winds singing welcome to the dawn. 【导语】本文以人物为线索展开，讲述了午夜时分，救援员Harry和David紧急进山搜救森林里最后一头野生小象“独角兽”。他们循着血迹，在大雾中艰难搜寻，最终找到受伤的小象并熟练为其止血急救。小象成功获救，两人如释重负，迎来黎明。 【详解】 1.段落续写： ①由第一段首句内容“然而，他们要找到它其实并非易事”可知，第一段可描写他们循着血迹，在大雾中艰难搜寻，最终找到受伤的小象。 ②由第二段首句内容“没有丝毫耽搁，Harry俯身开始对它的伤口进行急救处理”可知，第二段可描写他们为小象止血急救，小象成功获救，两人如释重负，迎来黎明。 2.续写线索：寻找小象——发现小象——对小象急救——小象获救——感悟 ★话题词汇 行为类 ①寻找：search for/look for ②叫喊：cry/shout/yell ③实施：conduct/carry out 情绪类 ①痛苦：painful/miserable ②疲惫的：exhausted/tired ★话题句式 【高分句型1】Thick fog came, covering almost everything.(运用了现在分词作状语) 【高分句型2】They had to bend down to search for clues like blood splashes or footprints, which made them walk more slowly, ears sharper than usual.(运用了which引导非限制性定语从句) 【救助小考拉】 ★名校真题【2026届浙江杭州高一期末】 In Sydney, Australia, there was a wildlife sanctuary(野生动物保护区) named “Bush Haven Sanctuary”, nestled in the lush forests on the outskirts of the city. The sanctuary cared for a variety of injured Australian animals, including playful kangaroos, curious koalas, talkative parrots and fat wombats(袋熊). It was a popular spot for families and nature lovers, who came to learn about wildlife conservation and interact with the gentle creatures. However, a sudden outbreak of an infectious plant disease forced the sanctuary to close to the public in early March this year, with the closure expected to last at least three months to prevent the disease from spreading further. Without the crowds of visitors, the sanctuary fell into an unusual silence. The animals, which had grown accustomed to the daily presence of humans — their laughter, gentle touches, and curious questions — now only saw the sanctuary staff. Soon, strange changes began to happen. The young koala named Lila, who once loved climbing onto visitors’ laps to have some eucalyptus(桉树) leaves, stopped eating properly and spent all day huddled in the corner of her tree hollow, refusing to move. One afternoon, after the caretaker Mia placed a fresh pile of eucalyptus branches in Lila’s cage, the koala didn’t even glance at them. She just stared blankly at the empty path where visitors used to walk. “She’s never been like this before,” Mia muttered anxiously. Dr. Carter, a wildlife veterinarian(兽医), was called to check on Lila. He examined her thoroughly and ruled out any physical illness. “Her body is healthy, so it might be stress or something related to the environment,” he said, scratching his chin thoughtfully. “Maybe we can adjust her cage to make it more comfortable and see if that helps.” But a week later, Lila’s condition didn’t improve. She had lost weight, and her fur looked dull. Desperate, the sanctuary team held a meeting. “We’ve tried everything for her physical health,” Mia said, her voice heavy. “What else could be wrong?” Then, the oldest caretaker at the sanctuary, Grandpa Joe, spoke up slowly: “Could it be that Lila misses the visitors? She’s always been the most social koala here.” While everyone was doubtful, they agreed to give Grandpa Joe’s idea a try. Mia played the sounds of visitors laughing and talking, which she had recorded before the closure. They also put some items that visitors usually brought, like toys and hats, near the cages. At first, Lila just stared at these things. But after a while, she slowly moved out of her tree hollow and sniffed at the toys. Then she actually reached out and took a small hat in her paw, which made everyone in the room cheer with joy. As Lila’s spirits lifted, the sanctuary team realized the solution might work for other animals too. They did the same for the kangaroos, parrots and wombats. The kangaroos, which had been lying around lazily, started to jump around happily when they heard the familiar sounds. The parrots, which had stopped singing, began to chirp again. The wombats, which had been hiding in their burrows, came out and explored their surroundings. The sanctuary was once again filled with life and energy, and it was all because they understood the importance of the emotional connection between animals and humans. 【导语】本文以动物为线索展开，讲述了在悉尼“Bush Haven Sanctuary”野生动物保护区，一只名叫莉拉的小考拉因保护区关闭、游客减少而出现精神萎靡、食欲不振的情况，兽医检查后排除身体疾病，大家尝试各种方法无果后，老饲养员乔爷爷提出可能是莉拉想念游客，大家决定尝试乔爷爷的办法来改善莉拉状况的故事。 【详解】 1.段落续写： ①由第一段首句内容“虽然大家都心存疑虑，但还是同意试试乔爷爷的主意。”可知，第一段可描写大家为吸引游客模拟游客场景，莉拉逐渐恢复活力的过程。 ②由第二段首句内容“随着莉拉的精神好转，保护区团队意识到这个办法或许对其他动物也有效。”可知，第二段可描写团队用同样方法帮助其他动物，保护区恢复生机，强调人与动物情感联系的重要性。 2.续写线索：模拟游客场景——莉拉逐渐恢复——尝试帮助其他动物——保护区恢复生机——感悟人与动物情感联系 ★话题词汇 行为类 ①播放声音：play the sounds/let the sounds out ②放置物品：put the items/place the objects ③欢快地欢呼：cheer with joy/shout with joy/exclaim with delight 情绪类 ①开心地：happily/delightedly/joyfully ②充满希望：be full of hope/be hopeful ★话题句式 【高分句型1】Mia played the sounds of visitors laughing and talking, which she had recorded before the closure.

Among them, a special chick named Bulldozer became my closest friend. We named him for his funny, determined walk. Unlike other roosters, Bulldozer was gentle and quiet. My favorite memory was watching him do his happy dance around the yard. He would run towards me, his feathers shaking with excitement, and then circle me as if celebrating my arrival. My dad, who usually was busy with work, always had a smile for Bulldozer. He enjoyed the rooster’s company while gardening. My mom would save him little treats from the kitchen, like bits of vegetable, and he would eat gently from her hand. In the evenings, I would often sit on the back steps doing my homework, and he would settle quietly beside me. Those peaceful moments were my treasure. He was more than a pet; he was a listener to my secrets and a calm part of our family’s daily life. Bulldozer lived with us for several happy years, becoming a familiar and loved part of our neighborhood. However, one quiet autumn afternoon, something felt wrong. The yard was silent. Bulldozer, who was usually waiting for me at the fence, was nowhere to be seen. My heart dropped. We found him lying still under his favorite tree. He was gone, as if he had simply gone to sleep there. The vet said it was likely a peaceful, natural end due to his age. We buried him under that same tree. The yard felt incredibly empty. I missed his dance, his quiet company, and the simple joy he brought to our family every day. The happy memories we shared now felt bittersweet, and a deep sadness settled in my heart. 注意：1. 续写词数应为150个左右； 2. 请按如下格式在答题卡的相应位置作答。 For a long time, I couldn’t bring myself to visit the corner of the yard. Every time I passed by, memories of Bulldozer’s happy dance and quiet company rushed in, making my eyes tear up. I avoided his favorite tree, where we used to sit together after school, and even skipped playing in the yard. My parents noticed my sadness and tried to comfort me, saying Bulldozer had lived a happy life with us. But I still felt empty, as if a part of my childhood had gone with him. One morning weeks later, a soft sound from the corner pulled me from my thoughts. I walked over hesitantly and was surprised to see three fluffy chicks huddling under the tree — Bulldozer’s tree. My mom smiled and said they were from a neighbor, and we’d take care of them. As one chick walked towards me with a funny, determined step, just like Bulldozer, tears of joy rolled down my face. I knew Bulldozer’s warmth had never left; it lived on in these little lives, keeping our happy memories alive forever. 【导语】本文以祖父母的农场为线索，讲述了“我”童年最美好的回忆都在祖父母的农场，其中一只名叫Bulldozer的小鸡因独特的走路姿势和温柔安静的性格，成为“我”最亲密的朋友，陪伴“我”度过许多宁静快乐的时光；几年后，Bulldozer因年老自然离世，“我”将它葬在它最爱的树下，满心悲伤、难以释怀的故事。 【详解】 1. 段落续写： ① 由第一段首句“很长一段时间里，我都不忍心去院子的那个角落。”可知，本段可描写“我”失去Bulldozer后的悲伤与逃避，为下文看到新小鸡、被治愈做情感铺垫。 ② 由第二段首句“几周后的一个早晨，角落里传来的轻柔声响将我从思绪中拉回。”可知，本段可描述“我”的治愈与回忆的延续。 2. 续写线索：“我”不忍心去院子角落——路过回忆涌现、刻意逃避——父母安慰仍感空虚——角落的轻柔声响吸引“我”——看到树下的三只小鸡——发现一只小鸡像Bulldozer——“我”喜极而泣、释怀治愈——领悟到温暖与回忆永不消逝 ★话题词汇 行为类 ①避免：avoid/keep away from ②安慰：comfort/console ③蜷缩：huddle/curl up ④照料：take care of/look after ⑤. 永存：live on/remain forever 情感类 ①悲伤：sadness/sorrow ②温柔的：gentle/soft ★话题句式 【高分句型1】Every time I passed by, memories of Bulldozer’s happy dance and quiet company rushed in, making my eyes tear up.(运用every time引导时间状语从句，现在分词短语making my eyes tear up作结果状语) 【高分句型2】I knew Bulldozer’s warmth had never left; it lived on in these little lives, keeping our happy memories alive forever.(运用现在分词短语作伴随状语) 1 学科网（北京）股份有限公司 $
