The resulting study was able to divide the individuals into two previously identified types, as far as curiosity goes: the “busybody” who explores a lot of diverse information, and the “hunter” who stays on a more focused track when it comes to gaining knowledge. “The search engine allowed both introverts (内向) and extroverts to have equal opportunity in curious practice, a limitation in other studies of curiosity, while the ad－free search engine allowed individuals to truly be captains of their own curiosity ships，” says biophysicist Bassett. By recording pages as nodes (节点) and analysing how closely they were related, Bassett and her colleagues were able to find both busybodies and hunters in their pool of volunteers — those who tended to jump all around the search engine and those who were more likely to stay on closely related pages. However, the participants didn't always stick to one type of behaviour or the other, and to find out why the researchers used a well－being questionnaire given to the participants before the study began, covering topics like seeking out social interaction and tolerating stress.Based on the surveys, a need to fill specific knowledge gaps seemed to drive hunter－style behaviour, while a desire to seek out brand new information was an indicator of a busybody－style of search engine browsing (浏览) — taking larger leaps between nodes or pages.“We assume that a switch from hunter to busybody style might arise due to sensation seeking, or the tendency to pursue novel and exciting information，” says Bassett. These findings can be useful in a number of ways, including in informing approaches to teaching.Curiosity is also linked to emotional well－being: people who are more curious tend to be more satisfied with life and less anxious.By making sure information is available in ways that are accessible, we can encourage curiosity and promote contentment at the same time. 语篇解读：本文为一篇说明文。 文章介绍了在某个搜索引擎的帮助下研究者所做的关于两种主要的好奇心类型的研究，并得出结论：培养好奇心有助于人们焦虑的减轻和生活满足感的增加。 1．Why did the researchers use the search engine to do their study? A．It could arouse a higher level of curiosity. B．It charged no fees for browsing information. C．It enabled introverts to switch to extroverts. D．It caused no disturbance to study participants. 解析：选D　推理判断题。根据第三段可知，他们使用这一搜索引擎进行这项研究的一个原因是，它没有广告，参与研究的人员可以做自己好奇心的主人来进行网页浏览。由此推知，这一搜索引擎不会对参与研究的人员形成干扰。 2．What did the researchers find out about busybodies? A．They took smaller leaps between pages. B．They tended to browse loosely connected information. C．They were anxious to narrow specific knowledge gaps. D．They were more likely to stick to their type of behavior. 解析：选B　细节理解题。根据第二段中的“the ‘busybody’ who explores a lot of diverse information”及第五段中的“while a desire to seek out brand new information was an indicator of a busybody－style of search engine browsing (浏览) — taking larger leaps between nodes or pages.”可知，好事者风格的人喜欢跳转到不同的页面去探索大量信息。由此可知，他们倾向于浏览联系不紧密的信息。 3．What may drive hunters to become busybodies? A．The desire to seek novelty. B．A reduction in sensation seeking. C．A wish to know like－minded individuals. D．The need to dive deeply into a certain topic. 解析：选A　细节理解题。根据倒数第二段最后一句可知，对于寻求新奇的渴望可能促使猎人风格转变为好事者风格。故选A项。 4．What's the consequence of promoting people's curiosity? A．Well－rounded individuals. B．Increased feelings of contentment. C．Greater ability to figure out problems. D．More chances to become top teachers. 解析：选B　推理判断题。根据最后一段第二句可知，好奇心越强越会使人获得更多满足感。由此推知，激发人们的好奇心会增强人们的满足感。 B (2024·江苏镇江高三统考)Cooking or baking has become a common cure for stress or feeling down, but there might actually be some science behind it.A study conducted by researchers followed 658 people for two weeks and found that a little creativity each day can go a long way towards happiness and satisfaction in daily life. “There is growing recognition in psychology research that creativity is associated with emotional functioning，” Tamlin Conner, lead author on the study, explained.“However, most of this work focuses on how emotions benefit or prevent creativity, not whether creativity benefits or hampers (阻碍) emotional well－being.” By following detailed diaries kept by the study subjects, Conner found that in addition to feeling happier, people who worked on little creative projects every day also felt they were “flourishing” — a psychological term that describes the feeling of personal growth. This isn't the first time researchers have drawn a line connecting making food with positive feelings.In recent years, psychologists have started spending more time exploring cooking and baking as a therapeutic (治疗的) tool to help people dealing with things like depression and anxiety. “When I'm in the kitchen, measuring the amount of sugar or butter I need for a recipe — I am in control.” baker John Whaite said. For people like Whaite, who is suffering from manic depression, baking can help their mood by providing small tasks to focus on in a manner similar to meditation (冥想)．In order to put together a good meal, cooks have to be constantly in the moment, adding ingredients, adjusting the heat of the stove and tasting their food — all of which can be helpful techniques in treating some forms of mental illness. “A lot of us turn to baking when we're feeling low.” Melanie Denyer, the founder of a bakery designed to draw awareness to mental health conditions, says.“Some of us even started baking because they were ill and needed something simple as a focus.And there is genuinely something very therapeutic about baking.” Baking may not be a be－all and end－all cure for mental illness, but anyone in need of lifted spirits should consider pulling out the flour and warming up the oven. 语篇解读：本文是一篇说明文。文章介绍了一些创造性任务，比如烹饪和烘焙，有益于心理问题的治疗。 5．What is the focus of most psychology research on creativity and emotions? A．The benefits of creative projects on emotions. B．The impacts of emotion on creativity. C．The harm of creativity to emotional well－being. D．The effects of creativity on emotional well－being. 解析：选B　细节理解题。根据第二段第二句“然而，大部分的研究都集中在情绪如何促进或阻碍创造力，而不是创造力是否有利于或阻碍情绪健康。”可知，大多数关于创造力和情感的心理学研究的重点是情绪对创造力的影响。故选B项。 6．Why do some psychologists explore cooking as a therapeutic tool? A．To provide an alternative form of meditation. B．To promote healthy and balanced eating habits. C．To assist individuals in handling mental problems. D．To help people with serious physical illnesses. 解析：选C　细节理解题。根据第三段最后一句“近年来，心理学家开始花更多的时间探索将烹饪和烘焙作为一种治疗工具来帮助人们处理抑郁和焦虑等问题。”可知，一些心理学家探索将烹饪作为一种治疗工具是为了帮助个人处理心理问题。故选C项。 7．How did John Whaite benefit from baking? A．It won him some honors. B．It helped him gain a sense of control. C．It cured his depression through meditation. D．It enabled him to become more creative. 解析：选B　推理判断题。根据第四段中“当我在厨房里，测量一份食谱所需的糖或黄油的量时，一切尽在我的掌控之中。”可知，烘焙帮助他获得了一种控制感。故选B项。 8．What is the main idea of the passage? A．Cooking and baking are creative activities. B．Baking is a complete cure for mental illness. C．Small creative tasks lead to improved emotional well－being. D．Following recipes leads to personal growth in creativity. 解析：选C　主旨大意题。根据全文，尤其是文章第一段最后一句“研究人员对658人进行了为期两周的跟踪调查，发现每天一点创造力可以大大提高日常生活中的幸福感和满意度。”可知，本文主要讲述了小的创造性任务可以改善情绪健康。故选C项。 Ⅱ.阅读七选五 (2024·湖北部分学校联考)Humans are emotional beings who experience all kinds of emotions.Living a joyful life doesn't mean refusing painful emotions.Instead, it means developing a mindset (心态) that prefers a positive view of the world.At the same time, it means developing healthy ways to deal with difficult emotions.__9__ Joy strengthens relationships.When you have a positive attitude, you tend to approach the people in your life from a place of gratitude and love.__10__ You also tend to appreciate the strengths in others, rather than focus on what you don't like in that person.
