Li Hua used to eat a lot of junk food, but now he tries to consume (consumption) more vegetables and fiber, regardless of how busy he is. （习惯改变） 2. During his trip to Xinjiang, Li Hua tried local lamb kebabs, which consist of fresh lamb and peppers, and he thought the bold flavors were truly exceptional (exception). （文化体验） 3. To keep a stable (stability) weight, Li Hua believes fundamentally (fundamental) that eating in moderation (moderate) is more than following any extreme diet. (健康理念) 4. When he visited Guangzhou, the dim sum there was served (serve) in small quantities (quantity), and he was impressed by how fresh the ingredients (ingredient) were. (文化对比) 5. Li Hua’s mother always tells him that traditional (tradition) Chinese dishes, like red braised (braise) pork, should be enjoyed occasionally rather than every day. （适量原则） 6. Prior to his trip to the UK, Li Hua had never heard of haggis, but he decided to try it and found it to be somewhat strange yet surprisingly tasty. （跨文化体验） 7. Yesterday, Li Hua sliced (slice) off a piece of whole-grain bread and added a modest (modestly) amount of olive oil, realizing that the simplest recipes often create the most elegant (elegance) meals. (生活实践) 8. Eating a variety (vary) of colorful vegetables is an ideal way to get enough vitamins (vitamin), chewing (chew) your food slowly is also a smart trick for better digestion. （行动号召） 二、健康饮食句型仿写挑战 李华需要用规范的句型向同学们传达健康饮食的理念。请根据中文提示和括号内的关键词/短语，完成句子仿写，确保语法正确、语义连贯。 1. 李华曾经因为经常外出就餐并且偏爱口味浓烈的快餐，结果导致体重明显上升，上课时也总是感到疲惫不堪，不管他怎么努力都无法集中注意力。（lead to, regardless） Li Hua used to eat out frequently and show a strong preference for fast food with bold flavors, which eventually led to noticeable weight gain, and he would always feel tired and sluggish during class, regardless of how hard he tried to concentrate.

(经验传递，核心原则) 4. 李华建议同学们采用蒸、煮等健康的烹饪方式，因为这样可以减少摄入过多的油脂，从而更健康地消耗每日所需的热量。（intake , consume） Li Hua advises his classmates to use healthy cooking methods such as steaming and boiling, as this can help reduce the intake of excess fats and allow them to consume their daily calories in a healthier way. (细化建议，提供方法) 5. 李华坚信，改善心理健康的关键不在于追求某种单一的饮食诀窍，而在于建立稳定的饮食习惯，并且吃饭时细嚼慢咽以帮助身体更好地消化食物。（trick, stable, chew） Li Hua firmly believes that the key to improving mental well-being is not about pursuing some single dietary trick, but rather about establishing a stable eating habit and chewing his food slowly to help his body digest better. (主旨总结，呼应开篇) Part II 饮食文化与健康认知解码 经过前期的词汇积累和句型练习，李华对“健康饮食”有了初步认识。但他发现，很多同学对“吃什么、怎么吃”仍然存在误区。为了帮助大家科学认识饮食与健康的关系，李华在科普周策划了两场专题活动：一场聚焦“饮食与疾病的科学关联”，一场走进普通人的生活，探寻“整果食用”的健康诀窍。请你跟随李华一起，完成以下解码任务。 一、饮食真相：科学认知篇 科普周第一站，李华决定从“饮食与疾病”的科学视角切入。他找到了一篇最新的研究报告，探讨饮食中脂肪酸的平衡如何影响人体免疫系统对抗疾病的能力。这篇文章将帮助同学们理解：为什么“吃什么”不仅关乎体重，更关乎长远的健康。请阅读以下文章，完成相关任务。 改编原文选自2025东北三省三校二模C篇 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 The food you eat might be affecting your body’s ability to fight cancer cells in the digestive system, according to a recent study. The likely cause is an excess of certain omega-6 fatty acids（脂肪酸）, perhaps from ultra-processed foods in your diets, which may prevent another essential fatty acid, omega-3, from having anti-inflammatory (炎症) effects and fighting cancer cells. Dr. Timothy Yeatman, a senior lead author of the study published in Gut, the journal of the British Society of Gastroenterology, explained, “Mutations (突变) happen every day in the digestive system. Usually, with the help of chemicals or substances from omega-3s, the immune system quickly stops these mutations.” However, he believes that if the body is subjected to a long-term inflammatory environment due to an imbalance of omega-6s, common in ultra-processed and junk foods, it becomes easier for a mutation to take hold and harder for the body to fight it. A Western diet is often rich in omega-6 fatty acids, largely due to widely available seed oils often used to fry fast foods and produce ultra-processed foods that now make up approximately 70% of the US food supply. Linoleic acid, an omega-6 fatty acid found in corn, peanut, soybean, safflower, and sunflower oils, is the most common omega-6 in the US food supply. Many individuals have a significant imbalance of omega-6 to omega-3 in their bodies. A study from November 2015 revealed that levels of linoleic acid have increased by 136% in the fat tissue of Americans over the past fifty years. Dr. Bill Harris, a professor of internal medicine not involved in the study, suggests that it is not the omega-6s from ultra-processed foods that are the issue, but rather the scarcity of omega-3s in the American diet, as many dislike fatty fish such as mackerel, herring, and sardines, which are excellent sources of omega-3. He emphasizes, “Don't blame the omega-6s, it's not their fault — it’s the lack of omega-3 fatty acids that's the problem.” 1. What might happen if Americans maintain their current diet? A. Omega-3 level in their bodies will increase rapidly. B. Mutation rate in the digestive system will decrease significantly. C. Colon cancer risk may keep rising due to omega-6/3 imbalance. D. Ultra-processed foods will be replaced soon by healthier ones. 2. What can we learn from the text? A. Western diet is rich in omega-3 fatty acids. B. Linoleic acid is the only omega-6 fatty acid in US food supply. C. Linoleic acid level in the fat tissue of Americans has decreased. D. Seed oils are widely used in making ultra-processed and junk foods . 3. What does the underlined word “scarcity” in the last paragraph mean? A. Shortage. B. abundance. C. resistance. D. fright. 4. What's Dr. Bill Harris’s attitude towards blaming omega-6 fatty acids? A. Supportive. B. Indifferent. C. Opposed. D. Uncertain. 【答案】1-4 CDAC 5. 阅读表达 Do you agree with Dr. Bill Harris that the lack of omega-3s is the real problem, rather than the overabundance of omega-6s ? Why or why not ? Support your opinion with reasons. 1) Sample Answer (Yes): I agree with Dr. Harris. A balanced diet requires both omega-6 and omega-3 fatty acids. Instead of completely avoiding omega-6s, it is more practical to increase our intake of omega-3-rich foods like fatty fish, nuts, and seeds to restore balance. 2) Sample Answer (No): I disagree. The passage clearly states that an overabundance of omega-6s can create a chronic inflammatory environment. Even if we increase omega-3 intake, consuming too many ultra-processed foods rich in omega-6s may still cause health problems. 6. 主题词汇提取：描写“健康饮食” 核心维度 英文词块 中文意思 饮食成分 ultra-processed foods 超加工食品 excellent sources of ...的极佳来源 身体系统 the digestive system 消化系统 the immune system 免疫系统 健康风险 a long-term inflammatory environment 长期的炎症环境 be subjected to... 遭受/处于……之下 an imbalance of  ...失衡 ... takes hold ...扎根/形成 a significant imbalance 显著的失衡 饮食问题 be rich in... 富含…… be low in... 缺乏…… the lack of... …的缺失/不足 the scarcity of  ...的缺乏 二、生活镜像：细节观察篇 科普周第二站，李华把目光投向了日常生活中一个容易被忽视的东西——果皮。他发现很多人在处理果蔬时习惯性地削掉果皮，却不知道这样做可能错失了宝贵的营养。为了帮助同学们建立“整果食用”的健康理念，李华整理了一篇关于果皮营养价值与食用注意事项的科普文章。 改编自上海市七宝中学2024-2025学年高三下学期5月英语试卷，原文选自《国家地理杂志》 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项/选项中有两项为多余选项。 If you remove and throw away the peel of most fruits and vegetables, you might be cheating yourself out of nutrients, fiber, and phytochemicals — compounds found in plants. In some instances, the peel of some fruits has been shown to have antioxidant（抗氧化剂） levels that are much higher than the inside of the fruit. 1 Some food companies are adding fruit and vegetable peels to foods like bread and biscuits to make them healthier. 2 However, Keith Ayoob, a registered nutrition expert at the Albert Einstein College of Medicine in The Bronx, points out,”That’s where the nutrients are hidden.” “Colors have power because they indicate the presence of antioxidants,”which help protect cells from damage caused by pollutants, sunlight, and other sources of unstable composition called free radicals（自由基）. Because “the peel is the protective layer on fruits and vegetables, it tends to have concentrated compounds like phytochemicals that serve as defense mechanisms against the sun, rain, and pests（害虫）,” says Wendy Bazilian, a nutritionist and public health expert based in San Diego. “ 3 When you peel these fruits and vegetables, you literally peel off some of the nutrition.” That’s not to say you should eat the skin of every fruit and vegetable. Avoid eating the skin of pineapple, and always peel onions and garlic. 4 That's why it’s important to clean them thoroughly. “Rinse（冲洗） it under clean water and use a vegetable brush or paper towel on the skin,” advises Lisa Young, a nutrition professor at NYU. 5 . A. Those defense approaches guard our health, too. B. Let's continue to conduct further research on fruit peels. C. The potential health effects of consuming peels are so promising. D. People usually ignore the peels of dark-colored fruits and vegetables. E. Besides reducing food waste, eating the peels has nutritional benefits. F. Of course, you should wash organically grown produce, as well, to remove dirt and germs. G. It’s true that eatable skins of conventional fruits and vegetables may contain harmful remains. 【答案】1-5 CDAGF 6. 阅读表达 Do you agree with the author’s suggestion that people should eat more fruit and vegetable peels ? Why or why not ? Support your opinion with reasons. 1) Sample Answer (Yes): I agree. As the passage shows, peels are rich in nutrients, fiber, and antioxidants. Eating peels can also reduce food waste, which is good for the environment. However, I would make sure to wash them thoroughly first. 2) Sample Answer (No): I partially disagree. Although peels contain nutrients, the passage also points out that some peels may contain pesticide remains and that certain peels should be avoided. For conventionally grown produce, the risk of pesticide exposure might outweigh the nutritional benefits. 7. 主题词汇提取：描写“健康饮食” 核心维度 英文词块 中文意思 传统智慧 the peel of fruits and vegetables 水果和蔬菜的皮 a rich source of nutrients 丰富的营养来源 hidden nutrients 隐藏的营养成分 the protective layer 保护层 饮食认知 be cheating yourself out of... 错失…… indicate the presence of... 表明……的存在 help protect cells from damage 帮助保护细胞免受损害 serve as defense mechanisms 作为防御机制 饮食习惯 remove and throw away the peel 削掉并扔掉果皮 eat the skin of fruits and vegetables 吃水果和蔬菜的皮 clean them thoroughly 彻底清洗 rinse under clean water 用清水冲洗 饮食建议 avoid eating certain peels 避免吃某些皮 wash organically grown produce 清洗有机种植的农产品 use a vegetable brush or paper towel 使用蔬菜刷或纸巾 饮食问题 contain harmful remains 含有有害残留 remove dirt and germs 去除污垢和细菌 Part III健康行动：指南创作篇 模拟任务展示厅 经过前期的科普阅读和人物观察，李华对“健康饮食”有了更深刻的认识。他决定撰写一份“校园健康饮食行动指南”，向全校同学发出行动号召，帮助大家养成科学的饮食习惯。 假设你是李华。你校英语报正在举办以“健康饮食，活力校园”为主题的征文活动。请你写一篇宣传稿投稿，呼吁同学们养成健康的饮食习惯。对他目前的情况表示理解； 1.健康饮食的重要性； 2. 给出2-3条具体建议； 3. 发出倡议。 注意： 1. 词数80左右； 2. 可以适当增加细节，以使行文连贯； 3. 句式要求（请至少运用以下三种）: ·虚拟语气（suggest + sb.

First, I suggest that you should cut down on sugary drinks and highly processed foods, because they contain too much sugar and offer little nutrition. （虚拟语气+原因状语从句，建议一） Second, if you find it hard to cook at home, try to eat more fresh fruits and vegetables rich in fibre and vitamins. （条件状语从句，建议二） Finally, chew your food slowly so that your body can digest it better and absorb more nutrients. （结果状语从句，建议三） I believe that small changes can lead to big results. Let's work together to build a healthier and more energetic campus! （发出倡议） Yours sincerely, Li Hua 使用的句式： 虚拟语气、原因状语从句、结果状语从句、条件状语从句、非限制性定语从句、宾语从句 【详细解答】 Part II 饮食文化与健康认知解码 一、饮食真相：科学认知篇 【语篇导读】本文为一篇说明文。文章主要介绍了最近的一项研究，该研究表明饮食中的某些omega-6脂肪酸可能过多，这可能影响身体对抗结肠癌细胞的能力，并解释了omega-6和omega-3脂肪酸在体内的平衡对于免疫系统功能的重要性。 【解析】 1. 推理判断题。根据文章第一段“The food you eat might be affecting your body’s ability to fight cancer cells in the colon, according to a recent study. The likely offender is an overabundance of certain omega-6 fatty acids, perhaps from ultra-processed foods in your diets, which may prevent another essential fatty acid, omega-3, from having anti-inflammatory (炎症) effects and fighting tumors.(根据最近的一项研究，你所吃的食物可能会影响身体对抗结肠癌细胞的能力。罪魁祸首很可能是某些ω-6脂肪酸摄入过量，这些脂肪酸或许来自你饮食中的超加工食品，它们可能会阻碍另一种必需脂肪酸——ω-3脂肪酸发挥抗炎作用以及对抗肿瘤。)”以及第二段“However, he believes that if the body is subjected to a chronic inflammatory environment due to an imbalance of omega-6s, common in ultra-processed and junk foods, it becomes easier for a mutation to take hold and harder for the body to fight it.(然而，他认为，如果由于ω-6脂肪酸失衡（这种情况在超加工食品和垃圾食品中很常见），身体处于慢性炎症环境中，那么突变就更容易站稳脚跟，而身体也更难对抗它。)”可知，西方饮食常富含ω-6脂肪酸，导致ω-6和ω-3脂肪酸失衡，这种失衡可能会影响身体对抗结肠癌细胞的能力，使身体更难对抗突变，增加患癌风险。因此，如果美国人保持目前的饮食习惯，由于ω-6和ω-3脂肪酸失衡，患结肠癌的风险可能会持续上升。故选C。 2. 推理判断题。根据文章第三段“A Western diet is often rich in omega-6 fatty acids, largely due to widely available seed oils often used to fry fast foods and manufacture ultra-processed foods that now make up approximately 70% of the US food supply. Linoleic acid, an omega-6 fatty acid found in corn, peanut, soybean, safflower, and sunflower oils, is the most common omega-6 in the US food supply.(西方饮食通常富含ω-6脂肪酸，这在很大程度上是因为广泛使用的籽油，这些籽油常被用来油炸快餐食品，以及生产超加工食品，而超加工食品如今约占美国食品供应的70%。亚油酸是一种ω-6脂肪酸，存在于玉米油、花生油、大豆油、红花油和葵花籽油中，它是美国食品供应中最常见的ω-6脂肪酸。)”可知，籽油被广泛用于油炸快餐食品和制作超加工食品，快餐食品也属于垃圾食品的范畴，所以可以推断出籽油被广泛用于制作超加工食品和垃圾食品。故选D。 3. 词义猜测题。根据划线单词所在句“Dr. Bill Harris, a professor of internal medicine not involved in the study, suggests that it is not the omega-6s from ultra-processed foods that are the issue, but rather the scarcity of omega-3s in the American diet, as many dislike fatty fish such as mackerel, herring, and sardines, which are excellent sources of omega-3.(Bill Harris博士是一名内科教授，他并未参与这项研究。他认为，问题不在于超加工食品中的ω-6脂肪酸，而在于美国人的饮食中……ω-3脂肪酸，因为许多人不喜欢鲭鱼、鲱鱼和沙丁鱼等富含ω-3脂肪酸的多脂鱼类。)”可推测，美国人不喜欢吃富含ω- 3脂肪酸的鱼，所以ω- 3脂肪酸在他们的饮食中是缺乏的。因此划线单词的意思和“缺乏、不足”相似。选项A“shortage”，意为“缺乏”，与此相符。故选A。 4. 推理判断题。根据文章最后一段“Dr. Bill Harris, a professor of internal medicine not involved in the study, suggests that it is not the omega-6s from ultra-processed foods that are the issue, but rather the scarcity of omega-3s in the American diet, as many dislike fatty fish such as mackerel, herring, and sardines, which are excellent sources of omega-3. He emphasizes, “Don’t blame the omega-6s, it’s not their fault — it’s the lack of omega-3 fatty acids that’s the problem.”(Bill Harris博士是一名内科教授，他并未参与这项研究。他认为，问题不在于超加工食品中的ω-6脂肪酸，而在于美国人的饮食中缺乏ω-3脂肪酸，因为许多人不喜欢鲭鱼、鲱鱼和沙丁鱼等富含ω-3脂肪酸的多脂鱼类。他强调：“不要怪ω-6脂肪酸，这不是它们的错——问题在于缺乏ω-3脂肪酸。”)”可知，Bill Harris博士认为问题不在于超加工食品中的ω-6脂肪酸，而在于美国饮食中ω-3脂肪酸的缺乏。他强调不要责怪ω-6脂肪酸，这不是它们的错，问题在于ω-3脂肪酸的缺乏。因此，他对责怪ω-6脂肪酸持反对态度。故选C。 二、生活镜像：细节观察篇 【语篇导读】本文是一篇说明文。文章围绕果蔬果皮的营养价值展开论述，指出人们削掉果皮的行为可能错失了丰富的营养来源。文章通过引用营养学家的观点，解释了果皮中抗氧化剂和植物化学物的作用机制，同时提醒读者并非所有果皮都可食用，并强调了彻底清洗的重要性。文章旨在引导读者科学认识果皮的价值，养成合理的食用习惯。 【解析】 1. C本题考查段首句的引入功能。该段首句需要引出“吃果皮有益健康”这一核心观点。C项“食用果皮对健康的潜在影响非常有前景”作为段首句，先总述果皮对健康的积极前景，后文具体解释果皮富含营养、抗氧化剂等，形成“总—分”结构。若直接以“削掉果皮是错失营养”开头，则缺少对果皮价值的正面铺垫。其他选项中，A项涉及“防御机制”，E项涉及“减少食物浪费”，均不适合作为开篇总起句；B、D、F、G与段落主题关联不紧密。故选C。 2. D 本题考查段落内部的逻辑衔接。前一句说“一些食品公司正在把果蔬皮添加到面包、饼干等食物中，让它们更健康”；后一句却用 “However” 引出营养专家Keith Ayoob的话：“那才是营养藏的地方。”——这里存在一个转折：公司已经意识到果皮的营养并加以利用，但专家却指出“人们往往把营养扔掉”，暗示大众普遍没有重视果皮。因此，空格处需要填入一个能体现“人们忽视果皮”的句子，才能与后文的“However”形成对比。D项“人们通常忽略深色水果和蔬菜的皮”恰好符合。后文紧接着提到“颜色有力量，因为它们表明抗氧化剂的存在”，与D项中的“dark-colored”形成呼应。故选D。 3. A 本题考查句间衔接功能。该段以Wendy Bazilian的引言说明果皮中的化合物是植物抵御日晒、雨水和害虫的“defense mechanisms”，空格后强调“削掉果皮就等于削掉部分营养”。A项“Those defense approaches guard our health, too.”作为过渡句，既承接前文的“defense mechanisms”，指出这些植物防御方式同样能守护人体健康，又自然引出后文“削皮损失营养”的结论，形成“植物防御→有益人体→削皮可惜”的逻辑链条。故选A。 故选A。 4. G 本题考查对比喻论证的承接理解。前文Bazilian指出果皮是水果蔬菜的保护层，其中含有作为防御机制的化合物（against sun, rain, pests）。G项“这些防御机制也保护着我们的健康”中的“These defense approaches”指代前文提到的“defense mechanisms against the sun, rain, and pests”，将植物的防御机制与人体健康联系起来，自然引出后文“削掉果皮就是削掉营养”的结论，逻辑连贯。故选G。 5. F 本题考查段尾补充信息的逻辑。前文建议避免食用某些果皮（菠萝皮），并指出要彻底清洗。F项“传统种植的水果蔬菜的可食用皮可能含有有害残留”解释了为什么需要清洗以及为什么某些果皮需要避免食用——因为可能存在残留。该选项为前文的建议提供了科学依据，使论证更加完整。故选F。 2 学科网（北京）股份有限公司 $ 高中英语（人教版）选必二 Unit3 Food and Culture 单元复习作业（学生版） 情境创设： 为响应“健康中国”号召，你校本月开展“健康饮食宣传月”活动。李华被推选为“校园健康饮食推广大使”，他需要完成一系列任务：整理饮食健康核心词汇、调研同学们的饮食习惯、撰写一份健康饮食倡议书。请你帮助李华完成以下任务，和他一起成为健康饮食的传播者！ Part I 饮食健康词汇与句型储备库 李华需要先准备好宣传素材。他正在整理一份“健康饮食核心词汇清单”，并练习如何用规范的句型表达建议。请帮助他完成以下词汇变形和句型仿写练习。 一、 饮食核心词汇变形闯关 1.

(主旨总结，呼应开篇) Part II 饮食文化与健康认知解码 经过前期的词汇积累和句型练习，李华对“健康饮食”有了初步认识。但他发现，很多同学对“吃什么、怎么吃”仍然存在误区。为了帮助大家科学认识饮食与健康的关系，李华在科普周策划了两场专题活动：一场聚焦“饮食与疾病的科学关联”，一场走进普通人的生活，探寻“整果食用”的健康诀窍。请你跟随李华一起，完成以下解码任务。 一、饮食真相：科学认知篇 科普周第一站，李华决定从“饮食与疾病”的科学视角切入。他找到了一篇最新的研究报告，探讨饮食中脂肪酸的平衡如何影响人体免疫系统对抗疾病的能力。这篇文章将帮助同学们理解：为什么“吃什么”不仅关乎体重，更关乎长远的健康。请阅读以下文章，完成相关任务。 改编原文选自2025东北三省三校二模C篇 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 The food you eat might be affecting your body’s ability to fight cancer cells in the digestive system, according to a recent study. The likely cause is an excess of certain omega-6 fatty acids（脂肪酸）, perhaps from ultra-processed foods in your diets, which may prevent another essential fatty acid, omega-3, from having anti-inflammatory (炎症) effects and fighting cancer cells. Dr. Timothy Yeatman, a senior lead author of the study published in Gut, the journal of the British Society of Gastroenterology, explained, “Mutations (突变) happen every day in the digestive system. Usually, with the help of chemicals or substances from omega-3s, the immune system quickly stops these mutations.” However, he believes that if the body is subjected to a long-term inflammatory environment due to an imbalance of omega-6s, common in ultra-processed and junk foods, it becomes easier for a mutation to take hold and harder for the body to fight it. A Western diet is often rich in omega-6 fatty acids, largely due to widely available seed oils often used to fry fast foods and produce ultra-processed foods that now make up approximately 70% of the US food supply. Linoleic acid, an omega-6 fatty acid found in corn, peanut, soybean, safflower, and sunflower oils, is the most common omega-6 in the US food supply. Many individuals have a significant imbalance of omega-6 to omega-3 in their bodies. A study from November 2015 revealed that levels of linoleic acid have increased by 136% in the fat tissue of Americans over the past fifty years. Dr. Bill Harris, a professor of internal medicine not involved in the study, suggests that it is not the omega-6s from ultra-processed foods that are the issue, but rather the scarcity of omega-3s in the American diet, as many dislike fatty fish such as mackerel, herring, and sardines, which are excellent sources of omega-3. He emphasizes, “Don't blame the omega-6s, it's not their fault — it’s the lack of omega-3 fatty acids that's the problem.” 1. What might happen if Americans maintain their current diet? A. Omega-3 level in their bodies will increase rapidly. B. Mutation rate in the digestive system will decrease significantly. C. Colon cancer risk may keep rising due to omega-6/3 imbalance. D. Ultra-processed foods will be replaced soon by healthier ones. 2. What can we learn from the text? A. Western diet is rich in omega-3 fatty acids. B. Linoleic acid is the only omega-6 fatty acid in US food supply. C. Linoleic acid level in the fat tissue of Americans has decreased. D. Seed oils are widely used in making ultra-processed and junk foods . 3. What does the underlined word “scarcity” in the last paragraph mean? A. Shortage. B. abundance. C. resistance. D. fright. 4. What's Dr. Bill Harris’s attitude towards blaming omega-6 fatty acids? A. Supportive. B. Indifferent. C. Opposed. D. Uncertain. 5. 阅读表达 Do you agree with Dr. Bill Harris that the lack of omega-3s is the real problem, rather than the overabundance of omega-6s ? Why or why not ? Support your opinion with reasons. ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 6. 主题词汇提取：描写“健康饮食” 核心维度 英文词块 中文意思 饮食成分 超加工食品 ...的极佳来源 身体系统 消化系统 免疫系统 健康风险 长期的炎症环境 遭受/处于……之下 ...失衡 ...扎根/形成 显著的失衡 饮食问题 富含…… 缺乏…… …的缺失/不足 ...的缺乏 二、生活镜像：细节观察篇 科普周第二站，李华把目光投向了日常生活中一个容易被忽视的东西——果皮。他发现，很多人在处理果蔬时习惯性地削掉果皮，却不知道这样做可能错失了宝贵的营养。为了帮助同学们建立“整果食用”的健康理念，李华整理了一篇关于果皮营养价值与食用注意事项的科普文章。 改编自上海市七宝中学2024-2025学年高三下学期5月英语试卷，原文选自《国家地理杂志》 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项/选项中有两项为多余选项。 If you remove and throw away the peel of most fruits and vegetables, you might be cheating yourself out of nutrients, fiber, and phytochemicals — compounds found in plants. In some instances, the peel of some fruits has been shown to have antioxidant（抗氧化剂） levels that are much higher than the inside of the fruit. 1 Some food companies are adding fruit and vegetable peels to foods like bread and biscuits to make them healthier. 2 However, Keith Ayoob, a registered nutrition expert at the Albert Einstein College of Medicine in The Bronx, points out,”That’s where the nutrients are hidden.” “Colors have power because they indicate the presence of antioxidants,”which help protect cells from damage caused by pollutants, sunlight, and other sources of unstable composition called free radicals（自由基）. Because “the peel is the protective layer on fruits and vegetables, it tends to have concentrated compounds like phytochemicals that serve as defense mechanisms against the sun, rain, and pests（害虫）,” says Wendy Bazilian, a nutritionist and public health expert based in San Diego. “ 3 When you peel these fruits and vegetables, you literally peel off some of the nutrition.” That’s not to say you should eat the skin of every fruit and vegetable. Avoid eating the skin of pineapple, and always peel onions and garlic. 4 That's why it’s important to clean them thoroughly. “Rinse（冲洗） it under clean water and use a vegetable brush or paper towel on the skin,” advises Lisa Young, a nutrition professor at NYU. 5 . A. Those defense approaches guard our health, too. B. Let's continue to conduct further research on fruit peels. C. The potential health effects of consuming peels are so promising. D. People usually ignore the peels of dark-colored fruits and vegetables. E. Besides reducing food waste, eating the peels has nutritional benefits. F. Of course, you should wash organically grown produce, as well, to remove dirt and germs. G. It’s true that eatable skins of conventional fruits and vegetables may contain harmful remains. 5. 阅读表达 Do you agree with the author’s suggestion that people should eat more fruit and vegetable peels ? Why or why not ? Support your opinion with reasons. ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 6. 主题词汇提取：描写“健康饮食” 核心维度 英文词块 中文意思 传统智慧 水果和蔬菜的皮 丰富的营养来源 隐藏的营养成分 保护层 饮食认知 错失…… 表明……的存在 帮助保护细胞免受损害 作为防御机制 饮食习惯 削掉并扔掉果皮 吃水果和蔬菜的皮 彻底清洗 用清水冲洗 饮食建议 避免吃某些皮 清洗有机种植的农产品 使用蔬菜刷或纸巾 饮食问题 含有有害残留 去除污垢和细菌 Part III健康行动：指南创作篇 模拟任务展示厅 经过前期的科普阅读和人物观察，李华对“健康饮食”有了更深刻的认识。他决定撰写一份“校园健康饮食行动指南”，向全校同学发出行动号召，帮助大家养成科学的饮食习惯。 假设你是李华。你校英语报正在举办以“健康饮食，活力校园”为主题的征文活动。请你写一篇宣传稿投稿，呼吁同学们养成健康的饮食习惯。对他目前的情况表示理解； 1.健康饮食的重要性； 2. 给出2-3条具体建议； 3. 发出倡议。 注意： 1. 词数80左右； 2. 可以适当增加细节，以使行文连贯； 3. 句式要求（请至少运用以下三种）: ·虚拟语气（suggest + sb.
