Recent findings show that adults fail to demonstrate the highest learning performance in this area. This paves the way for a fresh perspective on associative learning disorders，which are linked to the development of mental illness later in life. 素能提升练 Researchers from Ruhr University Bochum conducted groundbreaking experiments across four age groups：babies(0－3)，primary school children(6－12)，teenagers(13－19)，and adults.Participants were required to identify patterns between visual pictures and corresponding rewards through computer-based tasks.Several learning sessions were then integrated to assess performance stability. The research team was amazed by the results：“We'd initially assumed that associative learning improves continuously with increasing age，”says Dr.Carolin Konrad.However，there was a clear peak in performance at primary school：“Children at this age achieved the best results，learned most consistently and showed the least variability in their learning behavior.”Although adults and teenagers learned faster than babies，they didn't reach the performance level of primary school children. It also emerged that repeated exposure to the learned material plays a crucial role for babies and teenagers since an additional learning session led to an improvement in learning performance in these age groups.Teenagers improved 40% after additional practice sessions，whereas adults showed minimal progress.This finding highlights the “sensitive period” phenomenon —the brain's higher plasticity during childhood that allows more efficient knowledge strength. The study shows that associative learning is present across the lifespan but that the rates and quantities of learning vary.“This mental capacity not only helps us avoid dangers but also influences emotional regulation patterns，”concludes Konrad.“Early identification of association of associative learning difficulties could serve as an indicator for future mental health risks.” 语篇解读　本文是一篇说明文。文章主要介绍的是不同年龄段在联想学习能力上的差异，以及儿童期学习的高效性对心理健康的影响。 1．Which is an example of associative learning？ A．A baby grasps an object placed in its hand. B．A student works harder after getting good grades. C．A driver keeps speeding up when receiving a ticket. D．A cook follows his recipe despite customer complaints. √ 细节理解题。根据第一段中的“The ability to connect an event with its consequences—experts use the term associative learning—is a crucial skill for adapting to the environment.”可知，联想学习是指将事件与其结果联系起来的能力，B选项中“学生因为取得好成绩而更加努力学习”符合这一定义，因为它体现了事件(取得好成绩)与结果(更加努力学习)之间的关联。故选B项。 2．What were the participants required to do in the experiments？ A．Identify the relationship between different groups. B．Watch and record their own performance over time. C．Assess their learning progress during the sessions. D．Pair pictures with rewards through computer-based tasks. √ 细节理解题。根据第二段中的“Participants were required to identify patterns between visual pictures and corresponding rewards through computer-based tasks.”可知，参与者需要通过计算机任务将图片与奖励配对。故选D项。 3．What surprised the researchers about associative learning？ A．Adults possessed greater adaptability. B．Primary schoolers outperformed others. C．Teenagers peaked in learning performance. D．Babies required frequent exposure to knowledge. √ 推理判断题。根据第三段内容可知，研究人员惊讶地发现，小学生阶段的孩子取得了最佳成绩，学习最稳定，学习行为的差异性最小，由此可知，小学生在联想学习中的表现优于其他年龄段的人群。故选B项。 4．Why is the “sensitive period” phenomenon mentioned in Paragraph 4？ A．To show learning ability differences across all ages. B．To advise adults to learn efficiently in a gradual way. C．To stress the significance of learning during childhood. D．To demonstrate the brain's ability to adapt in adulthood. √ 推理判断题。根据倒数第二段中的“This finding highlights the‘sensitive period’phenomenon—the brain's higher plasticity during childhood that allows more efficient knowledge strength.”可知，儿童时期大脑的高可塑性使知识学习更高效，由此可推知，第四段中提到“敏感期”是为了强调儿童时期学习的重要意义。故选C项。 B (2024·湖北阶段练习) I have been a health care assistant with Marie Curie for four years.What led me to join this remarkable organization was a deeply personal experience. Seven years ago，my father was in the hospital，and I was informed that he was in the end-of-life stage.He had wanted to be at home during his final moments，so I arranged for him to return home.He spent only one more night there，but he wasn't alone.A Marie Curie nurse was by our side.Facing the emotions that come with knowing a loved one is at the end of their life can be heartbreaking.Having a nurse with us made it easier to deal with these feelings.That's when I made the decision to join Marie Curie. Working for the charity，I find myself on duty during most holidays.We operate every single day，including holidays.You might assume that being with families，knowing it's a difficult time for the person they're caring for，would be a sad experience.But what may surprise you is that it's not.The families，in my experience，are not sad.They make the most of the time they have left and they remain positive for everyone knows what's coming.They understand that their loved one is dying，but it's not a time for sorrow—it's a time of togetherness and warmth.I remember one particular family—three sisters—and the fourth was in the end-of-life stage.When I arrived，she was in a critical condition，and I knew she might not make it through the night. But sitting with the sisters，talking about their childhood，recalling what happened in the past was a special time.They mentioned that their sister had asked for peaches and cream earlier that day，and they made sure she got what she wanted.She went to sleep，and we lost her that night. We can't change what happens to us，but we can make a difference.We provide support through the stages of sadness and struggles.And，surprisingly，people may not suffer that much. 语篇解读　本文是一篇记叙文。文章主要讲述了作者加入Marie Curie这个为临终患者提供医疗服务的机构的原因，以及自己加入后的一些经历和感受。 5．What can we learn about Marie Curie from the text？ A．It is a remarkable health care organization for benefit. B．It is one of the most volunteer organizations in the world. C．It won't offer the service during some important festivals. D．It can be a big comfort to those facing their beloved ones' death. √ 推理判断题。根据第二段中“A Marie Curie nurse was by our side...made it easier to deal with these feelings.”和第三段中“You might assume that...The families，in my experience，are not sad.”可知，在作者自己的经历以及其他患者家属的经历中，Marie Curie的工作人员为患者的家属提供了一些安慰和照顾。由此可推知，对于那些面对亲人死亡的人来说，这个机构是一个很大的安慰。故选D。 6．Why does the author call the family mentioned in Paragraph 3 “particular”？ A．Because of the special relationship between them.

B．Misfortune might be an actual blessing. C．Where there is action，there is difference. D．All things are difficult before they are easy. √ 推理判断题。根据最后一段内容可知，作者认为人无法改变不幸，但却可以通过提供支持来削弱那种痛苦。由此可推知，作者想表达的是哪里有行动，哪里就有不同。故选C。 8．Which of the following can best describe the volunteers in Marie Curie？ A．Devoted and caring. B．Gifted and generous. C．Hard-working and honest.
