Since then，Sophie founded the Alternative Limb Project (ALP)to make artistic limbs.Her work includes an arm wrapped in sculpted snakes and a leg that looks like porcelain (瓷器)covered in a painted flowery vine.She makes about six limbs per year，always including clients’ ideas so that they receive a personal piece they can celebrate rather than hide. Of course，a fancy-looking limb won’t suit everyone.For Sophie，the basis is that each limb must satisfy a combination of comfort，beauty and functionality，and pushing too hard in one direction can weaken other areas.But for amputees who appreciate novelty，Sophie has some amazing ideas. “I’d really like to make a candy-dispenser leg with colorful candies inside it，” she says.“Or a cuckoo-clock leg with a wooden bird that pops out every hour.” Her goal is to fashion a striking limb. “It’ll transform the limbs from an elephant in the room into a conversationpiece. ” 　　语篇解读　本文是一篇记叙文。文章主要讲述了Sophie为被截肢者设计独特假肢的经历和想法，展示了她的设计理念和对被截肢者需求的 关注。 1.Why did Pollyanna Hope come to Sophie？ A.She hoped to have a tailored limb. B.She intended to design a cartoon figure. C.She longed to expand the market for limbs. D.She expected to sell Sophie some odd ideas. √ 细节理解题。根据文章第二段“‘She wanted something a little different on her leg...other pigs riding a bicycle and eating ice cream.”可知，Pollyanna Hope来找Sophie的原因是希望有一个定制的假肢。故选A。 2.According to Paragraph 3，ALP aims to __________. A.boost users’ confidence B.sharpen users’ creativity C.improve Sophie’s sculpture skills D.extend Sophie’s art business √ 细节理解题。根据文章第三段内容可知，Sophie创立“ALP”是为了让客户有一件可以庆祝而不是隐藏的假肢，也就是为了提升用户的自信心。故选A。 3.What is the basis for Sophie’s works？ A.The novelty of the pattern tops the list. B.The balance of multi-needs comes first. C.Fashion is the best policy. D.Functionality is the key. √ 细节理解题。根据文章第四段“For Sophie，the basis is that each limb must satisfy a combination of comfort，beauty and functionality，and pushing too hard in one direction can weaken other areas.But for amputees who appreciate novelty，Sophie has some amazing ideas.”可知，对Sophie来说，作品的基础是每个肢体都必须满足舒适、美观和功能的结合。故选B。 4.What can be inferred from the underlined sentence in the last paragraph？ A.Sophie resolves to lead the fashion of limbs. B.Sophie plans to further transform artistic limbs. C.Amputees will feel at ease to talk about limbs. D.Amputees will have easy access to artistic limbs. √ 推理判断题。在英文中“an elephant in the room”比喻一些非常显而易见的，可是却一直被忽略的棘手问题。由此可知，这句话的意思指的是“将假肢的事变成日常话题”，也就是说Sophie希望被截肢者能够轻松地谈论假肢。故选C。 B (2025·吉林省洮南市第一中学高二下月考) Lena is a psychologist (心理医生)working in a high school.She is devoted to helping students who are struggling with mental health issues.Her days are filled with counseling (咨询)sessions and organizing workshops to educate students about mental health.One day，a student named Sarah came to Lena for help.Sarah had been feeling anxious about her schoolwork. Lena listened carefully to Sarah’s concerns and asked her questions to better understand her situation.Lena then developed a personalized plan for Sarah，including relaxation techniques，time management strategies，and a referral to a support group. Over the next few weeks，Lena worked closely with Sarah，meeting regularly to discuss her progress and adjust the plan as needed.Sarah gradually felt more in control of her emotions and her schoolwork.She even started to participate in extra-curricular activities and make new friends. Lena’s work doesn’t stop at the school gates.Beyond the school，Lena leads community activities.She organizes monthly “Mind Matters” talks at the local library，where she explains mental health through easy-to-understand stories and fun activities.During lockdowns，her online support groups became really important connections for lonely teens，making her known as a kind guide who links adolescents and the resources they can get. What makes Lena do all this？ Memories of her brother having a hard time with depression without saying anything，a personal experience of feeling really tired during training that taught her how important it is to take care of herself，and the many moments when students get their confidence back.To her，every counseling session gives a chance to change how society thinks turning silent struggles into open talks and helping those facing life’s challenges become stronger.She believes that by raising awareness and breaking down shame，she can help create a more supportive and understanding environment for everyone. 　　语篇解读　本文是一篇记叙文。文章主要讲述了高中心理医生Lena的日常工作和志愿者经历。 5.Why did Sarah come to Lena？ A.She was feeling stressed. B.She was flooded by her housework. C.She was suffering physical disease. D.She was defeated by boring courses. √ 细节理解题。根据第一段中的“One day，a student named Sarah came to Lena for help.Sarah had been feeling anxious about her schoolwork.”可知，Sarah一直焦虑不安，所以来找Lena寻求帮助。故选A。 6.What does the underlined word “referral” in Paragraph 2 probably mean？ A.Devotion. B.Recommendation. C.Approach. D.Punishment. √ 词义猜测题。根据第二段内容可推知，Lena为Sarah定制了一个方案，包括放松技巧、时间管理策略，还为她推荐了一个互助小组，所以referral的意思是“推荐”，与Recommendation“推荐”意思相近。故选B。 7.What does Lena think of her job？ A.Significant. B.Tiresome. C.Demanding. D.Depressing. √ 推理判断题。根据最后一段中的“She believes that by raising awareness and breaking down shame，she can help create a more supportive and understanding environment for everyone.”可知，Lena相信自己的工作是有意义的。故选A。 8.Which of the following can best describe Lena？ A.Talented and calm.
