【A篇】文章主要介绍了airfare deals(机票优惠)，机票预订如何达到最省钱。 一、开头总述 背景引入：购买机票的省钱建议五花八门，令人困惑（提前订/最后 一刻订、周几订票/出行最便宜，说法不一）。 解决方案：Expedia 2025年的《Air Hacks Report》为这些问题提供 了明确答案。 二、正文 小标题1：What is the cheapest day to book airline tickets? （订票的最便宜的日子是哪天？） 小标题2：What are the cheapest days to fly? （出行的最便宜的日子是哪天？） 小标题3：How far in advance should you book airline tickets to save money?（提前多久订票最省钱？） Hacks：口语里指「实用小技巧、省钱妙招、高效方法」 When it comes to finding the best airfare deals, advice can be confusing. Some travelers recommend booking well in advance, while others swear by last-minute deals. Additionally, opinions differ on which day of the week is best for booking flights and which days are cheapest to travel. Fortunately, Expedia's 2025 Air Hacks Report provides clear answers to these questions. What is the cheapest day to book airline tickets? When you're ready to purchase airfare for your next trip, set aside time on a Sunday to book. Based on Expedia's 2025 Air Hacks Report, booking on Sundays can save you up to 6% on domestic(国内的)flights and up to 17% on international flights compared to bookings made on a Monday or Friday. This trend has held true for three years in a row. What are the cheapest days to fly? The day your flight departs is another important factor in determining the cost of your airfare. For the cheapest flights, aim to fly on a Thursday or Saturday. If you're flying domestically, departing on a Saturday instead of a Sunday can save you up to 17%. For international travel, leaving on a Thursday rather than a Sunday can result in savings of up to 15%. How far in advance should you book airline tickets to save money? Many people assume that the earlier you book your flight, the cheaper your ticket will be. But that's not the case. In fact, booking an international flight just 18 to 29 days before departure will save you up to 17% compared to booking three months in advance. The sweet spot for domestic flights is one to three months before your trip. Booking then can save you 25% compared with tickets booked at the last minute. 21. How can you save money concerning domestic flights?( 细节理解) A. Purchasing tickets on Mondays or Fridays. B. Choosing flights leaving on Sundays. C. Flying on Saturdays instead of Sundays. D. Booking 18 to 29 days in advance.​ 22. What is a common misconception about booking flights?( 细节理解) A. Last-minute deals are best choices. B. Booking early guarantees low prices. C. Weekends are always more expensive. D. Airfare varies greatly from year to year.​ 23. What's the text? ( 文章出处) A.

However, in her 30s, a visit to her eye doctor revealed troubling news, her eyesight was declining. Over time, Jan faced increasing challenges, simple pleasures like reading became difficult, and driving at night turned dangerous as curbs(路沿)seemed to disappear into darkness. Eventually, Jan's condition progressed to geographic atrophy(GA), which can lead to permanent vision loss. This left her questioning, "Why me? Why now?" Knowing she couldn't face this diagnosis alone, Jan naturally turned to her 81-year-old mom, Carolyn, with whom she had always shared a special connection. GA forced Jan to give up aspects of her independence, so she leaned more on Carolyn for daily activities like cooking and reading. Jan loves to bake, and Carolyn is her trusted partner in the kitchen, assisting with tasks that require more precision. "I love that I can count on her," Jan said, "She helps me, but she's also my best friend." In 2023, during a conversation with her doctor, Jan learned of treatment options for GA, including IZERVAY, an injection (注射)designed to treat the condition. After starting treatment, she was relieved to find that her GA progression had slowed. Despite the challenges of GA, Jan and Carolyn have not let it stop their love for travel. In fact, it has given them more opportunities to enjoy what they cherish. They are already planning their next adventure cruise to celebrate Carolyn's 82nd birthday.

This has led many researchers to work on different approaches to passively cool buildings without the use of air conditioning. A fascinating new approach uses a bioplastic to dramatically reduce temperatures. The plastic material can be placed as a film and during peak sunlight hours can reflect 98.7 percent of sunlight. In lab measurements, the material can passively reduce temperature by up to 9.2°C. The material is made of polylactic acid(PLA), which is a common plastic made from plants, and it is constructed using a low-temperature separation technique, which makes it extremely reflective. "Our metafilm(超材料薄膜)offers an environmentally friendly alternative to air conditioning, which contributes significantly to carbon emissions," lead author Yangzhe Hou said in a statement. "The material reflects nearly all solar radiation but also allows internal building heat to escape directly into outer space. This enables the building to stay cooler than the surrounding air, even under direct sunlight." Outside of the lab, the material has shown that it can produce an average temperature drop of 4.9°C during the day and 5.1°C at night. It is also pretty stable-in a 120-hour test in an acidic and high ultraviolet(紫外线) environment, equivalent to eight months outside, the film maintained its cooling, with a drop of up to 6.5°C. "Unlike conventional cooling technologies, this metafilm requires no electricity or mechanical systems," added Dr Xianhu Liu. "By using biodegradable PLA, we are presenting a green alternative that offers high solar reflectance, strong thermal emission (热辐射), sustainability, and durability." This bioplastic seems to have a similar cooling power to another recent invention, the world's whitest paint, estimated to reflect 98.1 percent of sunlight and to keep painted surfaces 4.4°C cooler than ambient temperature. At night, it maintained a temperature of 10.5°C. The application of these passive cooling technologies could be revolutionary in keeping people cool without the need for more electricity usage. 28. What is one advantage of PLA? ( 细节理解) A. It is widely available. B. It is cheaper than regular plastics. C. It dissolves quickly under sunlight. D. It can store more heat during the day.​ 29. What is Xianhu Liu's attitude to the bioplastic metafilm? ( 观点态度) A. Neutral. 中立的 B. Critical.批判的；批评的 C. Positive. 积极的；肯定的 D. Doubtful.​怀疑的 30. Why does the author mention "the world's whitest paint"? ( 细节理解) A. To promote both inventions together. B. To compare two different cooling methods. C. To criticize the limitations of the bioplastic. D. To explain how white paint reduces pollution.​ 31. What does the word "ambient" in paragraph 6 mean? ( 词义猜测) A. Average. 普通的；平均的；一般的 B. Surrounding. 周围的；附近的 C. Constant. 持续的；不断的；恒定的 D. Extreme. 极端的；极度的 四大类必背态度词 积极正向 positive 积极的、supportive 支持的、favorable 赞同的、optimistic 乐观的 消极负面 critical 批判的、negative 否定的、doubtful/skeptical 怀疑的、worried 担忧的 中立客观 neutral 中立的、objective 客观的、informative 知识性的（纯介绍） 干扰错项（几乎不选） indifferent 冷漠的、uninterested 不感兴趣、biased 偏见的、confused 困惑的 高考规律：作者写文章不会冷漠 / 偏见 / 困惑，优先排除。 1. 抓情感形容词、副词 重点锁定：fortunately、amazingly、unfortunately、regrettably、surprisingly 等感情色彩词，直接定态度。 2. 看转折逻辑 but / however / yet / although 后才是真实态度；转折前多为铺垫，答案必看转折之后。 3. 区分两类主体 作者态度：看全文结尾、总结句、评价句 文中人物态度：只看该人物的直接引语、观点句，不要混为一谈 方法 高频易错点突破 科普 / 说明文、新闻报道 → 大多选 objective/neutral 客观中立 议论文、社会现象 → 多含 critical 批判 或 positive 支持 有改进建议、期待展望 → 常考 optimistic 乐观 只陈述事实、无褒贬 → 绝不选褒贬类词汇 【D篇】文章是一篇科研报道类说明文，研究发现，首次出现精神病发作且伴有皮肤问题的患者，经治疗后更易出现抑郁、自杀等不良后果，皮肤问题或可成为精神健康风险预警，未来还需进一步研究验证。 段落 核心功能 关键信息 段 1 提出结论 精神疾病患者 + 皮肤问题 = 更高的抑郁 / 自杀风险 段 2 说明过程 481 名样本，皮肤问题比例，治疗流程 段 3-4 分析结果 具体数据对比，确认皮肤问题与不良后果的关联 段 5-6 总结与展望 预警意义 + 胚胎层原因，说明后续研究计划 Scientists have found that people receiving treatment for mental health conditions who also have skin problems may face a higher risk of severe outcomes, including depression and suicidal(自杀的)thoughts. The research, which could help doctors better identify vulnerable patients and tailor psychiatric care, was presented at the ECNP meeting in Amsterdam. The study involved 481 individuals experiencing their first episode of psychosis(精神病). Among them, 14.5% showed signs of skin issues (24% of females and 9.8% of males), including rashes(皮疹), itching, or sensitivity to light. All participants received four weeks of antipsychotic treatment, after which researchers assessed various mental health indicators. Dr. Joaquin Galvan explained; After 4 weeks of follow-up, patients with a first episode of psychosis presenting with skin conditions experienced higher levels of depression and risk of suicide. We found that just 7% of the patients without the initial skin conditions had suicidal thoughts or attempts, in contrast, around 25% of the patients with initial skin conditions had suicidal thoughts or attempts. Initial skin conditions are also linked to greater depression and poorer well-being at follow-up. "This discovery suggests that the presence of skin conditions indicates that these patients are more at risk for worse outcomes than patients who do not have skin conditions after a first episode of psychosis." The team noted that, if further research supports these results, skin symptoms could serve as an early warning sign for high mental health risks, much like how blood tests can signal the likelihood of cancer or heart disease. Because both the brain and skin develop from the same embryonic layer called the ectoderm, the scientists set out to explore how these two systems might be connected. As far as we know this is the first study to show this link in patients with psychosis, so we need follow-up studies to confirm the finding. We also need to understand if this link applies also to a range of other psychiatric conditions, such as bipolar disorder, ADHD, anxiety or depression. 32. What did researchers do after the four-week treatment? ( 细节理解) A. They checked mental health signs. B. They gave more antipsychotics. C. They asked about skin history. D. They recorded skin changes. 33. Why did scientists study the brain and skin? ( 细节理解) A. They have same functions. B. They grow from one layer. C. They affect each other directly. D. They cause similar diseases. 34. What do we know about the study? ( 细节理解) A. It has confirmed the link fully. B. It covers all psychiatric conditions. C. It needs more studies to support it. D. It has solved mental health issues. 35. What is the best title for the text? (主旨大意--标题归纳） A. How to Treat Psychosis Effectively B. Skin Problems; Causes and Cures C. Mental Health, New Treatment Ways D. Skin Issues and Mental Health Risks 标题归纳题解题方法 1. 抓主题句（首段 / 尾段 / 段首转折） 说明文、议论文：主题多在首段尾句或第二段开头 记叙文：主题常在结尾升华 出现转折词（but/however/yet/while/in fact），转折后是重点 2. 找高频复现词（主题词） 全文反复出现的名词 / 名词短语，基本就是核心话题，标题必须包含它。 3. 用 “三看” 快速判断 看范围：不能太大（太空泛），不能太小（只概括一段） 看对象：必须包含文章主要说明 / 论述对象 看态度：记叙文、议论文要体现作者情感或观点 4. 代入验证（最实用技巧） 假设用这个标题写一篇文章，是否和原文内容一致？不一致直接排除。 【完形填空】本文主要讲述了中国女孩李梅转学到巴黎高中后，因午餐与法国同学不同而遭遇嘲笑，后来在历史老师发起的“食物与文化周”项目中，通过展示中国传统食物煎饼，改变了同学们的看法，促进了文化交流，让大家建立起联系的故事。 冲突开端 第 1 段（前文） 李梅转学到巴黎高中，因午餐（蒸米饭）和法国同学不同，被 Pierre 嘲笑 转折契机 第 2 段前半部分 历史老师 Dupont 发起 “Food & Culture Week” 项目，要求学生展示传统美食及文化意义；李梅犹豫后选择家乡煎饼 化解融合 第 2-3 段 展示日李梅紧张准备，Pierre 主动帮忙并道歉；煎饼大受欢迎，同学道歉、友好相处，还提议合做中法食谱 主题升华 第 4-5 段 完成《Bites Beyond Borders》食谱书，李梅领悟食物是文化交流的桥梁；老师总结 “食物是最好的外交政策” While her French classmates ate salads, Li Mei took out a package of steamed rice.
