第十五周 | 周一 (限时15分钟　满分：22.5分) Ⅰ.阅读理解(每小题2.5分，共10分) (2025·安徽合肥高三模拟)As a popular subject of study among evolutionary ecologists, three­spined stickleback (三刺鱼) is known for their different shapes, sizes, and behaviours—they can even live in both seawater and freshwater, and under a wide range of temperatures.But what makes that? The researchers tracked six populations of the fish before and after seasonal changes to their environment，using genome sequencing (基因组测序)．Seasonal changes result in great changes in habitat structure and balance of salt and freshwater，and only those fish able to tolerate these rapid changes survive into the next season. “These changes probably resemble the habitat shifts experienced by stickleback populations during the past 10，000 years，”says Professor Barrett.“We hope to gain insight into the genetic changes that may have resulted from natural selection long in the past.” Remarkably，the researchers discovered the evidence of genetic changes driven by the seasonal shifts in habitats, which mirrored the differences found between long­established freshwater and saltwater populations.“These genetic changes occurred in independent populations over a single season，highlighting just how quickly the effects of natural selection can be detected，”says Professor Barrett.“The findings suggest that we may be able to use the genetic differences to predict how populations may adapt to environment.” The research emphasizes the importance of studying species in dynamic environments to gain a better understanding of how natural selection operates.In further research, they plan to investigate how repeatable the observed genetic changes are，by testing whether they show up year after year.Doing so would demonstrate their ability to reliably forecast the evolutionary future of these populations. 1．What does the underlined word “that” refer to in Paragraph 1？(　　) A.Stickleback can adapt to different living conditions.

D．The background of the research. 3．What is the main reason for stickleback's survival？(　　) A．Habitat shifts. B．Genetic change. C．Seasonal changes. D．Independent populations. 4．Why will scientists study the repetition of the genetic changes？(　　) A．To know what natural selection is. B．To study species in dynamic environments. C.To test the reliability of the present discoveries. D.To forecast the evolutionary future of certain species. Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2025·广东高三联考)If you've ever been bitten by a mosquito, you know how frustrating their bites can be.1(____),__creating an itch (痒) that once you start scratching only seems to get worse.Why does a mosquito bite itch and what can we do? Why does a mosquito bite itch? When a mosquito bites you, it pierces the skin using a special mouthpart to suck up blood and injects saliva (唾液) into your skin.Mosquitoes' saliva has lots of proteins in it, some of which our body recognizes as foreign things, and our immune cells spring into action to try to fight them.2(____). It's actually the body's response to the foreign mosquito proteins, because it is trying to fight.That's why some people may only have a mild reaction to bites, while others, more sensitive to the foreign proteins, react with large areas of swelling that are more painful. What helps resist the urge to scratch? “Don't scratch”is the advice that most experts and health professionals give.As hard and sometimes unrealistic as it can sound, scratching inflames (使更棘手) the skin, and the inflammation makes the skin itch more.“3(____)，”warned Daniel Markowski, technical adviser for the American Mosquito Control Association, adding that in extreme cases, people can scar themselves. Instead, there are dozens of creams and sprays that promise itch relief as well as home remedy (疗法)．Choosing what's right for you can often come down to trial and error.In general, all of the various anti­itch creams are very similar.There is no scientific evidence that these remedies work, and they can come with their own precautions or side effects.4(____). 5(____) Some people can have serious allergic reactions to mosquitoes, although in practice it is rare, Vosshall said.If you experience severe symptoms such as breathing trouble, you should seek medical attention immediately. A．When to seek medical attention? B．What to do with a mosquito bite? C．It's not the bite that causes the itch D．The more you scratch, the more they itch E.The little red bumps swell up almost immediately F．Scratching can cause secondary infections and prolong the irritation G．In fact, the best remedy to fight the itch is to prevent a bite in the first place 参考答案： Ⅰ.语篇解读：本文是一篇说明文。三刺鱼可以适应不同的生活条件，研究人员对此展开研究， 发现三刺鱼通过基因变化去适应环境。这一研究发现可以预测某些物种的进化未来。 1．解析：选A。代词指代题。第一段画线词的前一句指出，作为进化生态学家的一个热门研究课题，三刺鱼以其不同的形状、大小和行为而闻名——它们甚至可以在海水和淡水中生活，并在大范围的温度下生活。由此可知，第一段最后一句对三刺鱼可以适应不同的生活条件提出疑问，故that指的是“三刺鱼可以适应不同的生活条件的能力”。故选A。 2．解析：选C。段落大意题。由第二段的内容可知，研究人员通过基因组测序技术追踪了环境季节性变化前后的六个鱼类种群。季节的变化导致了栖息地结构和盐淡水平衡的巨大变化，而只有那些能够忍受这些快速变化的鱼类才能存活到下一个季节。综上可知，第二段主要讲的是研究方法。故选C。 3．解析：选B。细节理解题。第三段的最后一句“We hope to gain insight into the genetic changes that may have resulted from natural selection long in the past.”说到研究者希望深入了解可能是长期以来自然选择导致的基因变化。由此可知，三刺鱼生存的主要原因是基因变化。故选B。 4．解析：选D。细节理解题。根据最后一段的最后一句“Doing so would demonstrate their ability to reliably forecast the evolutionary future of these populations.”可知，科学家重复研究基因变化是为了预测某些物种未来可能的进化趋势。故选D。 Ⅱ.语篇解读：本文是说明文。本文主要讲述了为什么蚊子叮咬会痒、如何抵制抓挠的冲动以及何时就医。 1．解析：选E。根据空后的“creating an itch (痒)...to get worse”可知，你觉得痒，一旦你开始抓挠，(事情)似乎只会变得更严重，E项“这个小小的红点几乎会立即肿起来”符合语境，即承接上文说明被蚊子叮咬后的反应，又引出下文抓挠后的结果。 2．解析：选C。根据本段小标题“Why does a mosquito bite itch？”可知， 本段主要讲述为什么蚊子叮咬会痒。根据空后的“It's actually the...trying to fight”可推知，空处内容应与蚊子叮咬会痒的原因有关。故选C。 3．解析：选F。根据下文“adding that...scar themselves”可知，Daniel Markowski补充道，在极端情况下，人们会抓伤自己。据此可推知，上文应阐述抓伤(皮肤)产生的常见后果。F项“抓伤(皮肤)可能会导致继发感染并延长刺激时间”符合语境。 4．解析：选G。根据上文“There is no scientific...or side effects”可知，没有科学证据表明这些方法有效，而且它们可能有副作用。由此可推知，下文应提及对抗瘙痒的有效方法。G项“事实上，对抗瘙痒的最好疗法是首先防止被咬”符合语境。故选G。 5．解析：选A。根据本文结构可知，空处是本段的小标题，且应是一个问句。根据下文中的“If you experience...medical attention immediately”可知，本段主要围绕“就医”展开论述。A项“什么时候寻求医药治疗？”符合语境。故选A。 学科网（北京）股份有限公司 $
