Dieters who want to limit what they eat could have an unlikely supporter — big forks. Dieters who use them eat less than those with smaller forks, according to a study. The two-day experiment was conducted in an Italian restaurant. Tables were set with either a bigger fork or a smaller one — holding 20 percent more and 20 percent less food than the restaurant’s regular size. Each plate of food was weighed before it went out to a customer and when it came back to calculate how much food was left over. Diners given bigger forks ate less, leaving more on their plates. The authors of the study found that fark size helped diners see how far along they were toward finishing. With smaller forks, they did not feel much progress was being made so they put greater effort into satisfying their hunger — by eating more. Mr. Mishra said: “The fork size provided diners with a means to observe their goal progress. The physiological (生理的) feedback of feeling full or the satiation (满足) signal comes later. In its absence diners focus on the visual signal of whether they are making any dent on the food on their plate to assess goal progress.” The study, reported in the Journal of Consumer Research, concludes: “Grandma’s advice tells us to chew well so that our body has enough time to let us know that we are full. But given people’s busy lives, if we are not chewing longer, then using a larger fork may actually be more helpful in controlling over-consumption.” 1．What is the main idea of the passage? A．To introduce different factors affecting people’s eating habits. B．To discuss the impact of fork size on how much people eat. C．To compare the advantages and disadvantages of portion sizes. D．To explain the influence of food color on people’s eating behaviors. 2．What does the underlined word “dent” in the third paragraph probably mean? A．Decrease. B．Mark. C．Delay. D．Gap. 3．What is the study’s attitude towards Grandma’s advice in the last paragraph? A．It holds that the advice remains accessible in modern times. B．It thinks it’s too old-fashioned and out of date. C．It provides an alternative way based on the advice. D．It believes the advice is only applicable to certain foods. 4．Which of the following best describes the structure of the passage? A．Introduction — Experiment — Conclusion — Advice. B．Problem — Solution — Discussion — Suggestion. C．Opinion — Evidence — Analysis — Conclusion. D．Background — Research — Explanation — Advice. 【答案】 1．B 2．A 3．C 4．D 【导语】本文是一篇说明文。文章介绍了研究表明，使用大叉子能通过视觉信号帮助人们减少进食量，尤其在忙碌生活中可作为细嚼慢咽的替代方法。 1．主旨大意题。通读全文，尤其是第一段中“While previous research examined portion (一份饭) sizes, the colour of food and diners’ eating habit, researchers at the University of Utah in the U.S. assessed the impact of fork size. Dieters who want to limit what they eat could have an unlikely supporter — big forks. (之前的研究考察了食物的份量、食物的颜色和用餐者的饮食习惯，而美国犹他大学的研究人员评估了叉子大小的影响。想要限制食量的节食者可能会有一个意想不到的支持者——大叉子)”可知，文章围绕叉子大小对食量的影响展开，主要包括研究过程、分析和建议，结果表明大叉子能帮助减少进食量。故选B项。 2．词句猜测题。根据画线词的上文“The fork size provided diners with a means to observe their goal progress. The physiological (生理的) feedback of feeling full or the satiation (满足) signal comes later. In its absence diners focus on the visual signal (叉子的大小为用餐者提供了一种观察进食进度的方式。而饱腹的生理反馈或满足感信号会稍后才会出现。在没有它的情况下，用餐者会转而关注视觉信号)”和下文“to assess goal progress (以评估目标进度)”可知，叉子大小帮助食客在未感到饱腹的情况下观察进食进度，进度依据的是视觉上食物量有无“减少”，画线词意思应该是“减少”，与Decrease意思一致。故选A项。 3．推理判断题。根据最后一段中“Grandma’s advice tells us to chew well so that our body has enough time to let us know that we are full. But given people’s busy lives, if we are not chewing longer, then using a larger fork may actually be more helpful in controlling over-consumption. (祖母的建议告诉我们要好好咀嚼，这样我们的身体就有足够的时间让我们知道我们吃饱了。但考虑到人们忙碌的生活，如果我们咀嚼的时间不长，那么使用更大的叉子实际上可能更有助于控制过度进食)”可知，研究并未否定祖母充分咀嚼的建议，而是基于该建议提出替代方案以适应现实情况。故选C项。 4．推理判断题。文章第一段介绍研究背景，说明先前研究聚焦的因素，第二段描述研究实验，介绍餐厅的测试，第三段解释实验结果，分析叉子大小如何影响进食行为，第四段给出使用大叉子控制进食的建议，因此总体结构是“背景—研究—解释—建议”。故选D项。 七、七选五 （2025高一·全国·专题练习）The watermelon is sweet and juicy. It is the best time to eat it when it is hot. However, what you may not know is that eating watermelons has many health benefits and may even help you fight off disease. 1 Keep you hydrated. A medium-sized watermelon is about 92% water, so it’s a great option to keep you hydrated. 2 One cup of watermelon contains about 45 calories, making it a low-calorie snack. The high water content in watermelon can also be filling and help you eat fewer calories overall. A small 2019 study examining the effects of watermelon consumption on satiety and body weight in overweight and obese adults had been conducted. 3 It is obvious when they were compared with the group who consumed low-fat cookies with the same amount of calories. Prevent muscle soreness. 4 The way it works by opening blood vessels up allows for more blood flowing to the muscles which can decrease soreness by improving the supply of oxygen during exercise. Lower blood pressure. 5 Staying properly hydrated can also help improve blood pressure because it helps the heart pump blood to muscles more effectively. A small 2012 study found watermelon extract supplementation reduced blood pressure in obese adults with high blood pressure. A．The watermelon contains L-citrulline, an amino acid (氨基酸) that may help reduce muscle soreness after a workout. B．Reduce risk of disease. C．Here are so many health benefits of it! D．Assist in weight management. E．Because L-citrulline helps open and relax blood vessels, it can improve blood flow and lower blood pressure. F．Some studies have indicated lycopene may help protect against certain cancers. G．It found those who consumed two cups of watermelon daily for four weeks reported feeling less hungry and lost significantly more weight. 【答案】 1．C 2．D 3．G 4．A 5．E 【导语】本文是一篇说明文，主要介绍了吃西瓜对健康的诸多益处，包括保持水分、有助于体重管理、预防肌肉酸痛以及降低血压等。 1．根据上文“However, what you may not know is that eating watermelons has many health benefits and may even help you fight off disease.(然而，你可能不知道的是，吃西瓜有很多健康益处，甚至可能帮助你抵御疾病)” 及后文各要点可知，承上启下，引出下文对西瓜健康益处的具体介绍。C选项“以下是它的诸多健康益处！”符合语境，故选C。 2．根据下文“One cup of watermelon contains about 45 calories, making it a low - calorie snack. The high water content in watermelon can also be filling and help you eat fewer calories overall.(一杯西瓜大约含有 45 卡路里，是一种低热量的零食。西瓜的高含水量还能让人有饱腹感，有助于你总体摄入更少的卡路里)” 可知，本段在说吃西瓜有助于体重管理。D选项“有助于体重管理” 符合语境，作为小标题概括该段内容，故选D。 3．根据上文“A small 2019 study examining the effects of watermelon consumption on satiety and body weight in overweight and obese adults had been conducted.(2019 年进行了一项小型研究，考察食用西瓜对超重和肥胖成年人饱腹感和体重的影响)” 可知，此处应说明研究结果。G选项“研究发现，那些连续四周每天食用两杯西瓜的人表示饥饿感减轻，且体重明显下降” 符合语境。故选G。 4．根据下文“The way it works by opening blood vessels up allows for more blood flowing to the muscles which can decrease soreness by improving the supply of oxygen during exercise.(它通过扩张血管，让更多血液流向肌肉，在运动过程中通过改善氧气供应来减少酸痛)” 可知，此处应说明西瓜中有助于预防肌肉酸痛的成分。A选项“西瓜含有L-瓜氨酸，这是一种氨基酸，可能有助于减轻锻炼后的肌肉酸痛” 符合语境，故选A。 5．根据小标题“Lower blood pressure.(降低血压)”以及下文“Staying properly hydrated can also help improve blood pressure because it helps the heart pump blood to muscles more effectively.(保持适当的水分也可以帮助改善血压，因为它可以帮助心脏更有效地将血液泵入肌肉。)”可知，此处应说明西瓜降低血压的原因。E选项“因为 L-瓜氨酸有助于扩张和放松血管，它可以改善血液流动并降低血压” 符合语境，故选E。 八、完形填空 （24-25高二下·浙江嘉兴·期末）For all of elementary and middle school, and most of high school, I ate school lunch in the cafeteria.
