We’re calling on artists with a vision for happy, healthy oceans to submit sail designs for the Clean Ocean Sailing team. Design Specifications ● Submit a sail design that reimagines a more sustainable future and an ocean free from plastic pollutants. The background color of the sail will be black.

We are more than happy for designs to be drawn on an A4 piece of paper — just scan and send! ● If the winning design is hand drawn on paper, we will work with you and a designer to create a digitized version of your artwork!

TikTok videos promoting “anti-inflammatory diets” — which often require cutting out entire food groups like dairy and refined wheat products — have gained millions of views. These videos promise benefits such as weight loss and less stomach discomfort, making them especially popular among young users. 14 The key difference between short-term and long-term inflammation is often left out in these videos. Diet does play a key role in managing inflammation. A typical Western diet, high in processed foods and low in fresh produce, is linked to higher inflammation levels. 15 In this sense, some TikTok advice, like the possible benefits of whole-wheat foods, follows science, though more research is needed. 16 For most people, cutting out entire food groups without a medical reason lacks scientific support — such inflammation only happens in those with specific diseases like celiac disease (乳糜泻). 17 For everyone else, dairy and wheat products are generally safe and provide essential nutrients. In fact, many studies have found no connection between these foods and increased inflammation in healthy individuals. Systematic studies show dairy often has neutral or even positive effects on inflammation, and dairy products like yogurt and cheese are good for the balance of our gut bacteria. For healthy individuals, there is no need to cut out entire food groups. 18 Combine this with physical activity, quality sleep, limited alcohol, and not smoking to effectively manage inflammation and support the body’s natural defenses. A．However, TikTok’s common “avoid lists” are often misleading. B．Unnecessary restriction also risks missing out on important nutrients. C．Instead, focus on a balanced diet built around minimally processed foods. D．This type of short-term inflammation is actually helpful for fighting off infections. E．While the idea that diet influences inflammation is scientifically correct, the social media version is often too simple. F．In contrast, diets rich in fruits, vegetables, whole grains, and healthy fats — like the Mediterranean diet — can reduce inflammation. G．Some people believe that cutting out dairy alone can greatly improve inflammatory conditions. 四、完形填空 The other day, a bat (蝙蝠), ugly and black, flew into my house.

(我们呼吁有快乐、健康海洋愿景的艺术家为Clean Ocean Sailing团队提交帆船设计)”可知，船帆设计大赛的目的是请艺术家设计一个帆。故选A。 12．细节理解题。根据Design Specifications部分的“The background color of the sail will be black.

These videos promise benefits such as weight loss and less stomach discomfort, making them especially popular among young users.(TikTok上宣传“抗炎饮食”的视频——这类饮食通常要求摒弃诸如奶制品和精制小麦制品等整个食物类别——已经获得了数百万次的观看量。这些视频承诺能带来诸如减肥和减轻胃部不适等好处，因此在年轻用户中特别受欢迎)”以及后文“The key difference between short-term and long-term inflammation is often left out in these videos.(这些视频中常常忽略了短期炎症与长期炎症之间的关键区别)”可知，前文介绍抗炎饮食在抖音走红，后文指出这类视频刻意省略了短期/长期炎症的核心区别。E选项“虽然‘饮食影响炎症’这个概念符合科学，但社交媒体上的说法通常过于简化”承上启下，既肯定核心逻辑，又引出抖音说法的问题，符合语境。故选E。 15．根据上文“Diet does play a key role in managing inflammation. A typical Western diet, high in processed foods and low in fresh produce, is linked to higher inflammation levels.(饮食确实对控制炎症有着至关重要的作用。典型的西方饮食，富含加工食品而蔬果摄入量低，与较高的炎症水平密切相关)”以及后文“this sense, some TikTok advice, like the possible benefits of whole-wheat foods, follows science, though more research is needed.(从这个角度来看，TikTok上的一些建议（比如全麦食品可能带来的益处）是基于科学依据的，不过还需要更多的研究来证实这一点)”可知，前文提到高加工的西式饮食会提升炎症水平，后文提到抖音关于全谷物有益的建议符合科学。F选项“相反，富含果蔬、全谷物、健康脂肪的饮食（比如地中海饮食）可以降低炎症”和前文形成正反对比，也引出后文全谷物的科学性，逻辑通顺。故选F。 16．根据后文“For most people, cutting out entire food groups without a medical reason lacks scientific support — such inflammation only happens in those with specific diseases like celiac disease (乳糜泻).(对于大多数人而言，无缘无故地完全摒弃某些食物类别是没有科学依据的——这种炎症现象只会在患有特定疾病（如乳糜泻）的人群中出现)”可知，前文承认部分抖音内容有一定科学依据，后文提出“无医学原因切掉整类食物缺乏科学支持”。A选项“然而，抖音常见的‘禁食清单’往往具有误导性”转折引出错误观点，开启下文的反驳，符合语境。故选A。 17．根据前文“For most people, cutting out entire food groups without a medical reason lacks scientific support (对于大多数人而言，没有医学依据的情况下就完全摒弃某些食物类别，这种做法缺乏科学依据)”和后文“For everyone else, dairy and wheat products are generally safe and provide essential nutrients.(对于其他人来说，乳制品和小麦制品通常是安全的，并提供必要的营养素)”可知，前文讲无医学依据完全摒弃某些食物类别的做法缺乏科学依据，后文提到乳制品和谷物对普通人通常是安全的，并提供必要的营养素，选项B“不必要的限制也可能导致错过重要的营养素”既承接前文“无依据限制饮食”的行为，又引出下文“这些食物提供必要营养素”内容，符合语境。故选B。 18．根据上文“For healthy individuals, there is no need to cut out entire food groups.(对于健康人群而言，没有必要完全摒弃任何一类食物)”以及后文“Combine this with physical activity, quality sleep, limited alcohol, and not smoking to effectively manage inflammation and support the body’s natural defenses.(将此与适量运动、充足睡眠、限制饮酒以及不吸烟相结合，就能有效地控制炎症并增强身体的自然防御能力)”可知，前文指出健康人不需要戒断整类食物，后文提到“将它和运动、睡眠等结合起来控制炎症”。C选项“相反，应该专注于以低加工食物为基础的均衡饮食”给出正确做法，后文的this正好指代“均衡饮食”，衔接完美。故选C。 19．C 20．D 21．B 22．A 23．D 24．D 25．C 26．A 27．A 28．B 29．C 30．B 31．D 32．A 33．B 【导语】本文是一篇记叙文。文章讲述了作者作为家中男人，面对闯入屋内的蝙蝠时内心的恐惧与矛盾，反映了男性在社会角色期望下所感受到的困境与压力。 19．考查动词词义辨析。句意：作为“一家之主”，把这个可怕的家伙赶出房子是我的责任。A. rob抢劫；B. warn警告；C. clear清除，使离开；D.

34．考查连词。句意：但最近在西藏自治区举行的一次直播活动却有所不同。分析句子结构可知，此处需要填连词连接空前与空后的句子，结合句意可知，空前与空后两个句子间为转折关系，且位于句首，首字母需大写。故填But。 35．考查非谓语动词。句意：废塑料瓶，通常被视为对当地环境的极大破坏，以每瓶0.5元的价格出售，目的是提高人们对西藏污染问题的认识。分析句子结构可知，该句中已经有一个谓语动词were sold，且没有连词，所以此处应填非谓语动词，regard意为“认为”，与空前的名词Waste plastic bottles为被动关系，所以应为过去分词。故填regarded。 36．考查名词。句意：废塑料瓶，通常被视为对当地环境的极大破坏，以每瓶0.5元的价格出售，目的是提高人们对西藏污染问题的认识。此空位于冠词之后，介词之前，所以填名词，intend的名词为intention意为“目的，意图”。故填intention。 37．考查名词。句意：2019年，约有4000万游客访问西藏，导致约3.6亿个塑料瓶被遗弃在树枝、悬崖和河流中。此空处提示词为名词，前有about 40 million来修饰，在句中作主语，所以此处填名词复数。故填tourists。 38．考查冠词。句意：白色污染对当地生态系统和当地动物（如牦牛）构成严重威胁。此空提示词threat意为“构成威胁的事/人”时为可数名词，其前必须有限定词，结合句意可知此处表示泛指，填不定冠词，且空后serious的发音是以辅音音素开头，应用a。故填a。 39．考查动词时态。句意：在过去的几年里，超过5000名志愿者参加了反白色污染运动。分析句子结构可知，此处应该填谓语动词，由时间状语Over the past few years可知，应用现在完成时，主语more than 5,000 volunteers为复数，且与participate为主动关系。故填have participated。 40．考查副词。句意：大致而言，每瓶的价格约为0.5元。分析句子结构可知，此处填副词作状语，rough的副词形式为roughly，且位于句首，首字母要大写。故填Roughly。 41．考查介词。句意：直播成功地让更多的人参与了反白色污染运动，他们所做的确实有所作为。结合句意可知，此处表示的是“在……运动中”，介词应使用in。故填in。 42．考查主语从句。句意：直播成功地让更多的人参与了反白色污染运动，他们所做的确实有所作为。分析句子结构可知，此处引导主语从句，从句中缺少谓语动词have done的宾语，指的是“事情”。故填what。 43．考查代词。句意：这确实是一个有意义的事件，有助于使我们人类有可能与自然和谐相处。此空位于介词之后与human being的内容相同，作做介词的宾语，所以填we的宾格形式。故填us。
