We know that elephants are large.But did you know that elephants often avoid eating a type of acacia tree(金合欢树),because it is home to ants?And an elephant doesn’t want to get the ants inside its trunk.Its trunk is full of sensitive nerve endings. Female elephants live in groups of about 15 animals.The oldest in the group is the leader.She decides not only when and where they move but also when they rest all year round.Male elephants leave the female groups between age 12 and 15.But they aren’t loners.They live in all-male groups. Asian elephants don’t run.Running requires lifting all four feet at once.But elephants filmed in Thailand always keep at least two on the ground at all times. Elephants have passed the mirror test.They recognize themselves in a mirror.According to tests,great apes,and dolphins also have this ability. Elephants can get sunburned so they take care to protect themselves.“Elephants will throw sand on their backs and on their heads to keep them from getting sunburned and to keep bugs off,” said Tony Barthel,working at Smithsonian’s National Zoo.How do elephants protect their young?Adult elephants will put them in sand and then they will stand over the little ones as they sleep. Some farmers in Kenya protect their fields from elephants by lining the borders with beehives.Not only are their crops saved,but the farmers also get more money from honey. 1.Why is World Elephant Day designed? A.To show some facts about elephants. B.To call on people to protect elephants. C.To tell people some animals are in danger. D.To introduce Asian elephants’ features. 2.Why are elephants not willing to eat a type of acacia tree? A.Elephants are sensitive to acacia trees. B.Acacia trees are too tall to reach. C.Fruits on the acacia trees are hard to eat. D.Elephants’ trunks are easily hurt by ants in the trees. 3.What do we infer about male elephants? A.They live with female elephants at an early age. B.They decide when and where their groups move. C.Their oldest male elephant is chosen as their leader. D.They can run faster than female elephants. 4.How do elephants protect their young kids? A.Put some sand on kids’ heads. B.Guard kids when kids sleep. C.Pat kids’ backs from time to time. D.Use their trunks to keep bugs off. B (2026重庆高一上期末) Evolution(进化) can cause amazing changes in living things.For example,today’s songbirds came from wingless dinosaurs that lived millions of years ago.However,some animals seem to avoid these changes and stay almost the same.The coelacanth,a fish that still exists today,looks very similar to its 410-million-year-ago fossils. Scientists have long wondered how these species stay unchanged.It has been commonly believed that natural selection keeps some species unchanged through stabilizing selection. This selection favors average qualities,while directional selection favors extreme qualities that would cause a species to change. But a study published in the National Academy of Sciences USA goes against this idea,showing that evolution constantly offers different qualities to those seemingly unchanging animals to improve their short-term survival. In the long term,though,“all that evolution cancels out(相互抵消) and leads to no change,” says the study’s lead author,James Stroud. Stroud and his colleagues studied lizards,all relatively unchanged for 20 million years.The researchers caught members of lizard groups every six months for three years.They measured each lizard’s head size,leg length,mass and height,as well as the size of its sticky toes,recording which individuals survived.He saw clearer evidence of directional selection:some lizards with unique characteristics,such as stickier toes,survived better. “The study offers a good explanation,” says Tadashi Fukami,an ecologist studying evolution at Stanford University.Many new qualities are evolving in the short term,but they don’t provide a crucial advantage over the long term.In other words,species staying unchanged may simply have found the best possible combination of qualities for lasting success in their environment.So what happens when the lizards’ environment changes more significantly?To help answer this bigger question,Stroud is still making trips to visit the lizards. 5.What’s the purpose of mentioning the “coelacanth fish” in paragraph 1? A.To show the power of evolution. B.To add evidence to natural selection. C.To prove species’ great changes. D.To give an example of unchanged species. 6.What is paragraph 2 mainly about? A.A common belief. B.A sharp contrast. C.Unsolved mysteries. D.Unique characteristics. 7.How was Stroud’s research conducted? A.By analyzing lizard fossils. B.By tracking research objects. C.By explaining natural selection. D.By identifying different lizards. 8.What will Stroud probably do in the future? A.He will make trips to visit lizard experts. B.He will summarize average features of lizards. C.He will reveal the best combinations of qualities. D.He will examine lizards under extreme conditions. Ⅴ.七选五 (2026山东日照高一上期末) A small helping hand from a classmate is not just a kind act.Sometimes,it’s the exact thing that helps us get through a tough school day,or finish a task we could never manage alone.Teamwork is highly valued in high school group projects.On the face of it,splitting(划分) the work seems like the best way to go.　1　  Last Wednesday in a high school biology lab,I watched a group of students work on a plant growth experiment.Curious classmates gathered around the lab tables with their tools and materials.　2　 The first group got straight to work:They split the tasks clearly,with one measuring soil,another planting seeds,and the third setting up the light sources.Their experiment was well-organized from start to finish.  Next was a second group of four students.At first,they argued about who should do the easy parts,and no one wanted to take on the tiring job of watering the plants daily.　3　 They ended up mixing up the seed types by mistake,and their first batch of seeds failed to come out a week later.With a final effort,they put their differences aside,corrected their mistakes,and restarted the experiment together.  　4　 The first group received feedback like,“You finished so quickly—you’re such a great team!” The second group’s teacher also nodded in approval,saying,“You fixed your problems well and learned a lot from the process.”  Which group is likely to gain more useful experience for future projects?When groups only focus on finishing tasks quickly by splitting work,they may miss the chance to learn from each other.But when groups face problems together and solve them as a team,they develop better communication and problem-solving skills.　5　 Small disagreements are part of the journey,not a sign of failure.As a result,they will become more confident and better prepared to handle all kinds of group tasks in the future.  A.They learn teamwork matters less than hurrying to finish tasks. B.In both cases,the teacher made positive comments on their work. C.Proper teamwork helps students learn more than task completion. D.The key to successful teamwork is arranging tasks based on strengths. E.They wasted half an hour arguing,with original preparation in a mess. F.They were asked to observe seed growth under different light conditions. G.However,dividing tasks without communication may cause more problems.

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.请按如下格式在相应位置作答。 Upon arrival,he told his mother what was happening.              But

elephants.”可知,世界大象日是为了保护并拯救大象而设立的。故选B项。 2.D　推理判断题。根据第二段中的“But did you know that...Its trunk is full of sensitive nerve endings.”可知,大象经常不吃一种金合欢树,因为这种树是蚂蚁的家,大象不想让蚂蚁进入自己的鼻子,它的鼻子有很多敏感的神经末梢。由此推断这种金合欢树上大量的蚂蚁一旦爬到大象的鼻子里,会对大象敏感的神经末梢带来一定的伤害,所以大象不愿意吃这种树。故选D项。 3.A　推理判断题。根据第三段中的“Male elephants leave the female groups between age 12 and 15.”可推知,雄性大象幼年时(也就是12~15岁之前)是与雌性群体共同生活的。故选A项。 4.B　细节理解题。根据第六段的“Adult elephants will put them in sand and then they will stand over the little ones as they sleep.”可知,成年大象会让自己的孩子躺在沙子里,然后在幼象睡觉时守护着幼象。故选B项。 【语篇导读】本文是一篇说明文。文章探讨了物种如何在漫长岁月中保持外表“不变”这一科学问题,介绍了传统“稳定选择”理论以及Stroud团队通过对蜥蜴的长期追踪研究提出的新解释。 5.D　推理判断题。根据第一段中“However,some animals seem to avoid these changes and stay almost the same.The coelacanth,a fish that still exists today,looks very similar to its 410-million-year-ago fossils.”可知,作者用“However”转折引出有些动物几乎保持不变的现象,随后以腔棘鱼为例,说明其现状与4.1亿年前化石极为相似,因此提及腔棘鱼是为了举例说明“不变的物种”,故选D项。 6.A　主旨大意题。根据第二段中“It has been commonly believed that natural selection keeps some species unchanged through stabilizing selection.”可知,本段主要介绍了长期以来科学界普遍认为的“稳定选择”理论,即自然选择通过稳定选择使物种保持不变,故选A项。 7.B　细节理解题。根据第四段中“The researchers caught members of lizard groups every six months for three years.They measured each lizard’s head size,leg length,mass and height...recording which individuals survived.”可知,Stroud团队通过每六个月捕捉一次蜥蜴、持续三年的方式进行长期追踪观测,记录其各项特征及存活情况,故选B项。 8.D　推理判断题。根据最后一段中“So what happens when the lizards’ environment changes more significantly?To help answer this bigger question,Stroud is still making trips to visit the lizards.”可知,Stroud提出了环境发生更显著变化时蜥蜴会如何的问题,并仍在继续研究以回答这一更大问题,由此可推断他未来可能会研究环境发生更显著变化时,这些蜥蜴的情况,故选D项。 Ⅴ.【语篇导读】本文是一篇夹叙夹议文。文章通过对比高中生物课上两组学生进行植物生长实验的不同表现,探讨了团队合作的真谛——共同面对并解决问题的团队比单纯快速分工的团队能获得更多有益经验。 1.G　上文提到表面上分工似乎是最佳方式;下文转而描述两个实验小组的具体案例。G项通过“However”形成转折,指出单纯分工的潜在隐患,为后文两组不同经历做好铺垫。 2.F　根据上文可知,学生们已做好准备;下文提及土壤、种子和光源等具体操作。F项明确交代实验任务,使上下文语义连贯。 3.E　根据上文可知,第二组学生因分工争执不下;下文说明争执导致的混乱后果。E项承上启下,具体描述争执引发的时间浪费和准备混乱。 4.B　根据下文可知,老师对两组都给予了积极评价。B项概括两组共同点,引出后文具体评价内容。 5.C　根据上文可知,文章通过对比强调共同解决问题的深层价值;下文进一步阐述面对分歧的正确态度。C项精炼概括核心论点,即团队合作的价值超越任务完成本身。 Ⅵ.【语篇导读】本文是一篇说明文。文章主要介绍了中国西南部一家餐厅户外庭院发现的一亿年前恐龙足迹,包括发现过程、恐龙特征、足迹保存原因及保护措施等相关信息。 1.dating　考查非谓语动词。根据“have been discovered”可知,空处需填非谓语动词作后置定语;date back to与逻辑主语Dinosaur footprints之间是主动关系,故填dating。 2.where　考查定语从句。先行词是“several stone pits”,关系词在从句中作地点状语,故填where。 3.a　考查冠词。researcher为可数名词单数,且以辅音音素开头,此处表示泛指,故填a。 4.length　考查名词。根据定冠词“the”和介词“of”可知,空处需填名词形式,故填length。 5.that　考查固定句型。根据“so heavy”和“the ground must have shaken”可知,此处为so...that...固定句型,表示“如此……以至于……”。 6.destroyed　考查非谓语动词。根据“may get”和“by construction work”可知,get后接过去分词构成被动语态,表示“被破坏”,故填destroyed。 7.buried　考查非谓语动词。根据“with the dinosaur footprints”和“by layers of dirt and sand”可知,此处为with复合结构,footprints与bury之间是被动关系,需用过去分词作宾语补足语,故填buried。 8.was removed　考查被动语态。根据“about a year ago”可知,此处用一般过去时;主语The dirt与remove之间是被动关系,故填was removed。 9.natural　考查形容词。根据“the 　　　look of the stone”可知,空处需填形容词修饰名词look,表示“自然的”,故填natural。  10.further　考查副词比较级。根据“protect the footprints”可知,空处需填副词修饰动词protect;结合语境,设置栅栏是为了“进一步”保护足迹,故填further。 Ⅶ.Volunteer Recruitment for Wildlife Protection  Dear fellow students, To raise awareness of wildlife protection and take practical action to help endangered animals,our school is setting up a wildlife protection volunteer team.We’re looking for enthusiastic senior one students to join us! As volunteers,you’ll take part in campus publicity activities(like making posters),assist in local wildlife rescue center work on weekends,and share knowledge about animal protection online.No special skills are needed,but you must be responsible and love animals. If you’re interested,send your application to the Student Union email by October 20th.Let’s work together to protect our animal friends! Ⅷ.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.  知识积累卡 一、1.稳定的　使稳定　稳定性　2.证据　明显的　3.特征;特点　4.测量　测量结果　5.同意　不同意　分歧 二、1.拍成电影　电影　2.改正　正确的　3.双手捧起　茶杯 三、1.看起来像　2.短期来看　3.换句话说　4.自始至终 5.不小心,错误地　6.施工 四、1.普遍认为,自然选择通过稳定性选择使某些物种保持不变。 2.有时,正是它帮助我们度过艰难的学校时光,或是完成那些仅凭一己之力永远无法做到的任务。 五、后置定　伴随状　宾语　目的状 但《美国国家科学院院刊》上发表的一项研究反驳了这一观点,表明进化会不断赋予这些看似不变的动物不同的特性,以提高它们的短期生存能力。 1 学科网（北京）股份有限公司 $
