The research was conducted on more than 150 bees in Wageningen University’s bio-veterinary research laboratory. The scientists trained the bees by giving them a treat — a sugar-water solution — every time they were exposed to the scent of a mink (貂) infected with COVID-19. Each time the bees were exposed to a non-infected sample, they wouldn’t get a reward. Eventually, the bees could identify an infected sample within a few seconds — and would then stick out their tongues like clockwork to collect the sugar water. Bees aren’t the first animals to detect COVID-19 by scent. Researchers have also trained dogs to distinguish between positive and negative COVID-19 samples from human saliva (唾液) or sweat with fairly high levels of accuracy. A small German study found that dogs could identify positive COVID-19 samples 94% of the time. That’s because metabolic changes from the coronavirus make an infected person’s bodily fluids smell slightly different from those of a non-infected person. But researchers still aren’t sure whether animals are the best bet for sniffing out COVID-19 cases outside the lab. “No one is saying they can replace a PCR machine, but they could be very promising,” Holger Volk, a neurologist, told Nature. PCR machines are what lab technicians use to process standard COVID-19 swab tests. At the very least, certain animals could be useful for identifying COVID-19 in places or countries in which high-tech laboratory equipment is scarce or inaccessible. Wageningen scientists are working on a prototype of a machine that could automatically train multiple bees at once. Then bees can use their skills to test for coronavirus aerosols (气溶胶) in the surrounding environment.1．How did the researchers teach the bees to identify COVID-19?A．By offering bees some rewards. B．By infecting bees with COVID-19.C．By raising bees with sugar water. D．By exposing bees to infected humans.2．Why are dogs capable of finding out negative COVID-19 samples?A．For dogs can sniff out hidden virus of the samples.B．For dogs can tell the different smell of the samples.C．For dogs can feel metabolre changes of the samples.D．For dogs can distinguish saliva from sweat of the samples.3．What is the follow-up task of Wageningen scientists?A．To breed more multiple bees. B．To detect coronavirus aerosols.C．To help underdeveloped countries. D．To develop a new type of machine.4．Which can be a suitable title for the text?A．A New Way to Cure COVID-19 DiseaseB．Bees: Well-trained COVID-19 DetectorsC．Bees’ Extremely Accurate Sense of SmellD．The Best Method of Identifying COVID-1902（2022·广西北海·高三阶段练习）Dogs are born to socialise with people because we raise them that way. Two-month-old dogs can already recognise when people are pointing at objects and will stare at our faces when they’re spoken to—both signs that dogs have an innate capacity to interact with us through body language.“Although individual relationships with people might influence that behaviour, at least 40percent of this ability comes from genetics alone, “says Emily Bray at the University of Arizona. “Over the course of keeping dogs, there has been a clear selection for these social skills,” she says. “It’s something that’s deep in them and that comes out at a really young age even before they have much experience with humans.”Bray and her colleagues tested these types of skills in 375 eight-week-old dogs that were chosen to become service dogs. Bray says, “It was the earliest age when the dogs could carryout such experiments because they were only just old enough to be motivated by food rewards.”The researchers found that pointing at food hidden under a cup helped the dogs to find it nearly 70 percent of the time. The success rate was high from the start, meaning they weren’t learning to follow pointing, but had already known to do so. In a control test, the randomly selected dogs couldn’t find food hidden under one of the two cups at a higher rate, indicating that they weren’t simply smelling it. Much of the variation in different dogs’ abilities to follow finger-pointing is explained by genetics. Using statistical analyses based on the dogs’ parents and other relatives, the researchers found that genetic factors were responsible for much of these variations.The team also ran another experiment in which the researchers spoke “baby talk” to the dogs and found that the dogs fixed their eyes on the person for more than 6 seconds on aver-age, representing an understanding that the researchers were communicating with them.5．What does the underlined word “innate” in paragraph 1 probably mean?A．Weak. B．Natural. C．Secret. D．Complete.6．What’s the future mission of the 375 eight-week-old dogs?A．To serve humans. B．To take part in tests.C．To entertain researchers. D．To learn human body language.7．What mainly influenced the dogs’ success rate in finding the hidden food?A．Food smell. B．Their genes.C．Their habits. D．Professional training.8．How do dogs react to “baby talk”?A．Randomly. B．Confusedly.C．Sensitively. D．Absentmindedly.03（2022·广东深圳·高三阶段练习）The first time that I met a blind scientist. I worked in a program for disabled students interested in pursuing STEM (Science, Technology, Engineering, Maths) research. Until that point, it had never occurred to me how blind students were prevented from receiving science education. My daily experience in classrooms consisted of professors drawing and writing on the board with the assumption that students in the class could see. But what about those students who cannot see or suffer from vision problems?A recent paper from Baylor University, led by Katelyn Baumer and Bryan Shaw, was inspired by exactly this problem.They designed a study to assess whether people could learn to recognize 3D models, like those often used to teach science, with their mouths instead of with their eyes.A 202l paper in Nature found that primates(灵长类动物)showed the same brain circuit activation(激活)when grasping objects with their hands and when moving an object with their tongues.This indicates that there may be underlying similarities of physical manipulations(操纵)of the hand and the mouth.Baumer and Shaw found that there was comparable touch recognition with hands to mouth manipulation recognition when using these models. 365 college students and 31 primary school students participated in the study. The participants were blindfolded and then divided into two groups, one assigned to manipulate objects by hand, and one to manipulate the objects with only their mouths. Each participant was given a single model protein to study. They then were asked to identify whether each of a set of eight other protein models matched the original they were given.The research team saw that both age groups of students were able to successfully distinguish between models. Moreover, the accuracy of recalling the structures was higher in people who only assessed the models through mouth manipulation.Although this study did not involve blind or low-vision students, it sets the basis for expanding into them next. It may offer a way to have science become more accessible, which is the ultimate goal.9．Who will most probably benefit from Baumer and Shaw’s study?A．Professors. B．College students.C．Primary school students. D．Blind and low-vision students.10．What does the author intend to do in paragraph 3?A．Explain a concept to readers. B．Provide supporting information.C．Summarize the previous paragraphs. D．Introduce a new topic for discussion.11．What method is used in the study?A．Making comparisons. B．Doing surveys.C．Conducting interviews. D．Reviewing papers.12．What is the text mainly about?A．A recent paper about STEM education.B．A protein model used in science teaching.C．A potential way for disabled students to learn science.D．An academic program for blind scientists to do research.04（2022·江西·高三阶段练习）Music can really affect your well-being, learning, quality of life, and even happiness. The fact that music can make a difficult task more tolerable may be why students often choose to listen to it while doing their homework. But is listening to music the smart choice for students who want to improve their learning? A new study suggests that for some students, listening to music is a wise strategy, but for others, it isn’t. The effect of music on cognitive (认知的) function appears to depend partly on your personality—specifically, on your need for external stimulation (刺激). Researchers not only assessed listeners’ personality but also changed the difficulty of the task and the complexity of the music. Participants first completed a personality test used to determine the need for external stimulation. Then, they engaged in an easy cognitive task (searching for the letter A in lists of words) and a more challenging one (remembering word pairs) in order. Participants finished both tasks under one of two sound conditions:(1)no music, (2)with music. The data suggest that for those with a high need of external stimulation, on the simple task of finding A’s, the scores for the music condition were significantly worse than those for the silent condition. On the complex task of learning word pairs, their performance was worse whenever music was played. For those with a low need of external stimulation, however, on the simple task, such participants’ scores for the music condition were much better than those for the silent condition. On the complex task of learning word pairs, the participants showed a small but reliable benefit when listening to music. According to the study, there are individual differences in the impact of music on cognitive function. Students who are easily bored and who seek out stimulation should be cautious of adding music to the mix. On the other hand, students with a low need for stimulation may benefit significantly from the presence of music. With the right personality, the right music and the right task, the presence of music may significantly improve cognitive functioning. Given the benefits of music, subscription to Spotify will be rewarding!13．What can we learn about the study in paragraph 2?A．It only involved the participants’ response to music.B．Participants completed two tasks when composing songs.C．The difficulty of the two tasks decreased in the experiment.D．Participants were grouped by their need for external stimulation.14．What can we infer from the result of the research?A．The complexity of tasks might reduce the benefit of music.B．Students should listen to music when performing complex tasks.C．Students with less external stimulation perform badly with music.D．The presence of music benefits students who seek for external stimulation.15．What might the underlined word “Spotify” be?A．A travel guide. B．A psychology journal.C．A music platform. D．A personality test.16．What could be the best title for the article?A．Why is music essential in your study?B．Is music beneficial to your personality?C．How can music affect your external stimulation?D．Does music promote your cognitive performance?05（2022·山东·高三阶段练习）阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。If you were told to stop from breathing through your nose, could you do it? Journalist Nestor made ___17___for about 10 days, plugging up his nose and ____18____(breathe) only through his mouth as part of an experiment at Stanford University. The effects were systemic —sleeping troubles, high blood ____19____(press) and, of course, discomfort.Breathing is so automatic an activity ____20____ most of us never think about doing it.

Based on the results of the experiment, he published a book Breath: The New Science of a Lost Art, ____22____ he explores everything from the role our noses play ____23____ hormone regulation(激素调节) and digestion, to how some athletes build up the lung capacity(肺活量) ____24____(run) marathons in extreme conditions or dive in icy water for more than an hour at a time. The topic is seemingly simple an entire book about breathing? But ____25____ (actual) every chapter reveals new details about how body and breath work together at the same time.Nestor’s daring attitude and _____26_____(curious) were infectious: I not only noticed myself paying attention to my own breathing every time I sat down to read, but my new-found comfort with my own lungs even inspired me to go for my first jog in years.06（2022·重庆八中高三阶段练习）You’ve heard them before. Perfect voices, matching their speakers’ attitude, style, and appearance. Most people know how to recognize a good voice simply because they like it and feel attracted to it. ___27___There are reasons why specific voices feel much easier on the ears, and people describe them as smooth.Good voices usually sound warmer, friendlier, expressive, and controlled. However, a bad voice is the complete opposite. ___28___ The question is: ___29___ When we have a good conversation with someone, we tend to adjust the pitch (音高) of our own voice towards theirs. But when we find someone attractive, the opposite is true. For men, their pitch goes down, while for women, their pitch goes up. What’s more, lowering or raising your pitch might be a sin of how attractive we find our date, but it also makes the other person more attracted to us.But could putting on an accent help you to appear younger or more masculine (男子汉的)? Humans have a remarkable vocal range, but also a good ability to detect fakers. ___30___ -if we could go around deceiving (欺骗) people all the time with our voices , then the entire communication system would fail. At the end of the day, making your voice sound more attractive, better, or deeper is a matter of trying. ___31___ Practice your breathing, keep your pitch in mind, copy good speakers, and learn how to position your voice after you’ve examined it. Record yourself, and see what works and what doesn’t.A．So humans are not easily deceived.B．However, it’s not only a matter of taste.C．Spend some time in front of your mirror.D．Start more conversations with your friends.E．Do men and women always use the same pitch of voice?F．It often sounds annoying, hesitant, boring and never changes.G．Can we use our voice in the right setting to adapt to our needs?  参考答案：1．A    2．B    3．D    4．B 【导语】本文是一篇说明文。文章介绍了科学家训练蜜蜂监测新冠病毒。1．细节理解题。根据第二段第一句“The scientists trained the bees by giving them a treat — a sugar-water solution — every time they were exposed to the scent of a mink (貂) infected with COVID-19.(科学家们训练蜜蜂，每次让它们接触感染了COVID-19的水貂的气味时，就给它们一种糖水溶液)”可知，科学家是通过奖励的方式训练蜜蜂识别新冠病毒的。故选A。2．细节理解题。根据第三段第四句“A small German study found that dogs could identify positive COVID-19 samples 94% of the time. That’s because metabolic changes from the coronavirus make an infected person’s bodily fluids smell slightly different from those of a non-infected person.(德国的一项小型研究发现，狗识别出Covid-19阳性样本的准确率是94%。这是因为冠状病毒的代谢变化使感染者的体液气味与非感染者略有不同)”可知，狗能够辨别出新冠病毒阳性患者是因为它能闻出他们什么不同的味道。故选B。3．细节理解题。根据最后一段“Wageningen scientists are working on a prototype of a machine that could automatically train multiple bees at once. Then bees can use their skills to test for coronavirus aerosols (气溶胶) in the surrounding environment. (瓦赫宁根的科学家们正在研究一种机器的原型，这种机器可以同时自动训练多只蜜蜂。然后，蜜蜂就可以利用它们的技能来检测周围环境中的冠状病毒气溶胶。)”可知, 瓦赫宁根科学家的后续任务是研发一种新的机器。故选D。4．主旨大意题。根据第一段第一句“Scientists in the Netherlands have trained bees to identify COVID-19 through their sense of smell, according to a press release from Wageningen University.(荷兰瓦赫宁根大学的一份新闻稿称，荷兰科学家训练蜜蜂通过嗅觉识别COVID-19)”及下文介绍可知，本文主要介绍了科学家训练蜜蜂使它们可以检测新冠病毒。由此可知，B. Bees: Well-trained COVID-19 Detectors(蜜蜂：训练有素的COVID-19探测器)适合作本文最佳标题。故选B。5．B    6．A    7．B    8．C 【导语】本文是一篇说明文。文章记录了一个实验，表明狗天生就有与人互动的能力。5．词义猜测题。根据文章第一段“Dogs are born to socialise with people because we raise them that way. Two-month-old dogs can already recognise when people are pointing at objects(狗天生就会与人交往，因为我们把它们养大了。两个月大的小狗已经能认出人们指着什么东西)”可知，两个迹象都表明狗有与生俱来的能力可以通过肢体语言与我们互动。故innate与上文中出现的born应是同义词，B项“天生的”符合题意。故选B项。6．细节理解题。根据第三段“Bray and her colleagues tested these types of skills in 375 eight-week-old dogs that were chosen to become service dogs.(Bray和她的同事们在三百七十五只八周大的小狗身上测试了这些技能，这些狗被挑选出来成为服务犬。)”，可知，小狗们被选为服务犬是为了将来为人类服务。故选A项。7．细节理解题。根据第四段“Using statistical analyses based on the dogs’ parents and other relatives, the researchers found that genetic factors were responsible for much of these variations.(通过对狗的父母和其他亲属的统计分析，研究人员发现，基因因素是这些变异的主要原因。)”可知，不同的狗在辨别手指向的能力上的差异很大程度上可以用基因来解释。因此，主要是狗的遗传基因影响了狗找到隐藏的食物的成功率。故选B项。8．推理判断题。文章最后一段“The team also ran another experiment in which the researchers spoke “baby talk” to the dogs and found that the dogs fixed their eyes on the person for more than 6 seconds on aver-age (该团队还进行了另一项实验，研究人员对小狗说“婴儿语”，发现小狗盯着人看的时间平均超过6秒。)”。由此可知，狗对“baby talk”很敏感。故选C项。9．D    10．B    11．A    12．C 【导语】本文是一篇说明文。文章主要内容是：科学家发现人们用嘴学习可以达到和眼、手一样的效果，从而为盲人或弱视人群参与科学学习提供了一种解决办法。【详解】1.细节理解题。根据文章第一段中“But what about those students who cannot see or suffer from vision problems?(但是那些看不见或有视力问题的学生怎么办呢？)”和第二段中“A recent paper from Baylor University, led by Katelyn Baumer and Bryan Shaw, was inspired by exactly this problem.(由凯特琳·鲍默和布莱恩·肖为主的贝勒大学最近的一篇论文正是受到了这个问题的启发)”可知，盲人和弱视学生最有可能从该项研究中受益。故选D项。 2.推理判断题。文章第三段内容主要“A 202l paper in Nature found that primates(灵长类动物)showed the same brain circuit activation(激活)when grasping objects with their hands and when moving an object with their tongues.This indicates that there may be underlying similarities of physical manipulations(操纵)of the hand and the mouth.(2021年刊登在《自然》上的一篇论文发现灵长类动物用手抓握物体和用舌头移动物体时会显示同样的大脑回路激活机制。这说明手和嘴的物理操纵方面存在潜在的相似性。)”由此可知，本段主要为研究提供支持信息。故选B项。3.推理判断题。根据第四段内容“The participants were blindfolded and then divided into two groups, one assigned to manipulate objects by hand, and one to manipulate the objects with only their mouths. Each participant was given a single model protein to study. They then were asked to identify whether each of a set of eight other protein models matched the original they were given.(参与者被蒙上眼睛，然后分成两组，一组被分配用手操作物体，另一组只用嘴操作物体。每个参与者给予一个单一的模型蛋白质进行研究。然后，他们被要求确定另外八种蛋白质模型中的每一种是否与给他们的原始蛋白质模型相匹配。)”可知，本段主要介绍了研究者把受试人员分为两组，分别用手和用嘴操纵物体，每位受试者先学习一个蛋白质模型，然后让他们辨认一组八个模型中哪一个符合他们学习的模型，对比结果得出结论，因此主要采用了对比研究方法。故选A项。4.主旨大意题。本文主要介绍了科学家研究发现人们用嘴学习可以达到和眼、手一样的效果，从而为盲人或弱视人群参与科学学习提供了一种潜在的解决办法。故选C项。13．D    14．A    15．C    16．D 【导语】这是一篇说明文。文章通过实验来证明了在恰当的个性、恰当的音乐和恰当的任务的情况下，音乐的存在可以显著提高认知功能。13．细节理解题。根据文章第二段中“Researchers not only assessed listeners’ personality but also changed the difficulty of the task and the complexity of the music. Participants first completed a personality test used to determine the need for external stimulation. (研究人员不仅评估了听者的性格，还改变了任务的难度和音乐的复杂性。参与者首先完成了一项用来确定外部刺激需求的性格测试)”可知参与者们首先要完成性格测试，根据测试的结果来确定是否需要外部刺激，那么这两类人就根据他们对外部刺激的需求被分成不同的组别来进行试验。故选D项。14．推理判断题。根据文章第三段中“The data suggest that for those with a high need of external stimulation, on the simple task of finding A’s, the scores for the music condition were significantly worse than those for the silent condition. On the complex task of learning word pairs, their performance was worse whenever music was played.For those with a low need of external stimulation, however, on the simple task, such participants’ scores for the music condition were much better than those for the silent condition.On the complex task of learning word pairs, the participants showed a small but reliable benefit when listening to music.(数据表明，对于那些需要大量外部刺激的人来说，在寻找A的简单任务中，音乐条件下的分数比安静条件下的明显要差。在复杂的单词配对学习任务中，只要播放音乐，他们的表现就会变差。然而，对于那些对外部刺激需求较低的人来说，在简单的任务中，音乐条件下的参与者的分数要比安静条件下的参与者好得多。在复杂的单词配对学习任务中，参与者在听音乐时表现出了微小但可靠的益处)”可知通过对两组参与者实验后，发现在复杂任务中，需要大量外部刺激的人只要播放音乐，表现就会变差，而对于不太需要外部刺激的人来说，音乐只起一点点作用，远不及他们在简单任务中音乐所起的作用大。故推知在复杂任务中会降低音乐的益处；故选A项。15．词句猜测题。根据文章最后一段“With the right personality, the right music and the right task, the presence of music may significantly improve cognitive functioning. Given the benefits of music, subscription to Spotify will be rewarding!(有了恰当的个性、恰当的音乐和恰当的任务的情况下，音乐的存在可以显著提高认知功能。考虑到音乐的好处，订阅Spotify可能会为自己带来回报)”可知提到了订阅“Spotify”会有回报，而本文意在阐述音乐对提高认知功能的影响，故推知本文是一篇由音乐平台所发布的文章，来给人们揭露并宣传音乐对于认知功能的影响，故推知划线单词“Spotify”指的是一个音乐平台；故选C项。16．标题判断题。根据文章第一段“But is listening to music the smart choice for students who want to optimize their learning?(但是，对于想要优化学习的学生来说，听音乐是明智的选择吗)”可知，文章第一段提出了一个音乐到底对学生来说是不是一个明智的选择这样一个问题，文章接下来的段落通过一个实验来证明音乐到底是否有利于提高认知功能；文章最后一段“the presence of music may significantly improve cognitive functioning.(有了恰当的个性、恰当的音乐和恰当的任务的情况下，音乐的存在可以显著提高认知功能)”总结出到底音乐是否能提高认知功能这一问题的答案；故本文一直是围绕音乐是否能提高认知能力这一话题来进行阐述的，选项D“Does music promote your cognitive performance(音乐能提高你的认知能力吗)”适合作为本文标题；故选D项。 17．it    18．breathing    19．pressure    20．that    21．makes    22．where    23．in    24．to run    25．actually    26．curiosity 【导语】这是一篇说明文，记者Nestor通过自己的经历以及和一些专家的谈话中表明，呼吸方式影响全身的健康。17．考查固定短语。句意：作为斯坦福大学实验的一部分，记者Nestor用鼻子堵住鼻子，只用嘴呼吸，成功坚持了大约10天。make it成功，到达，固定短语。故填it。18．考查现在分词。句意同上。此处和plugging并列，应用现在分词作状语，故填breathing。19．考查名词。句意：其影响是全身性的——睡眠障碍、高血压，当然还有不适。此处和前后的名词sleeping troubles及discomfort并列，应用名词形式，pressure压力，不可数名词，故填pressure。20．考查结果状语从句。句意：呼吸是一种自动的活动，我们大多数人从来没有想过要做它。此处是so…that…引导的结果状语从句，表示“如此……以至于……”，故填that。21．考查时态和主谓一致。句意：但正如Nestor通过自己的经历以及与数十名专家的交谈所表明的，我们的呼吸方式对身体的整体健康有影响。句子是描述一个事实，应用一般现在时，主语the way是名词单数，谓语动词用第三人称单数形式。故填makes。22．考查定语从句。句意：根据实验结果，他出版了《呼吸：一种失落艺术的新科学》一书，在书中，他探索了从我们的鼻子在激素调节和消化中的作用，到一些运动员如何在极端条件下跑马拉松或在冰冷的水中潜水超过一个小时而增强肺容量的一切。分析句子可知，空处引导非限制性定语从句，先行词是a book Breath: The New Science of a Lost Art，关系词在从句中作地点状语，应用关系副词where，故填where。23．考查介词。句意同上。play a role in…在……中起作用，固定搭配。故填in。24．考查动词不定式。句意同上。结合句意可知，此处表示目的，应用动词不定式作目的状语。故填to run。25．考查副词。句意：但实际上，每一章都揭示了身体和呼吸如何同时协同工作的新细节。此处应用副词作状语，修饰整个句子，故填actually。26．考查名词。句意：Nestor大胆的态度和好奇心很有感染力：我不仅注意到自己每次坐下来看书时都在注意自己的呼吸，而且我对自己的肺新发现的舒适感甚至激励我这么多年来第一次慢跑。空处和名词attitude并列，应用名词作主语，curiosity好奇心，不可数名词。故填curiosity。27．B    28．F    29．G    30．A    31．C 【导语】本文是篇议论文。文章讲述了好的声音让人更有吸引力，人们该如何练习好的声音。27．上一句“Most people know how to recognize a good voice simply because they like it and feel attracted to it.”（大部分人知道如何认出一个好声音只是因为他们喜欢这个声音，感到被吸引。）和下一句“There are reasons why specific voices feel much easier on the ears, ”（有许多原因说明为什么特别的声音更易被耳朵识别）说明好声音容易被听出来不仅仅是人们喜好的问题，这里应为转折关系。故选B。28．上一句“ a bad voice is the complete opposite. ”（一个糟糕的声音完全相反。）设空处与这句为顺承关系，继续说明糟糕的声音的特点。F选项的主语“It”指代“a bad voice”,且后面的句意相符。故选F。29．根据“The question is: ”可知，此处应选问句。根据下一句“ When we have a good conversation with someone, we tend to adjust the pitch (音高) of our own voice towards theirs.
