Children who were overweight had family meals that included more negative emotional interactions compared to children who weren’t overweight.Non-overweight children’s meals tended to have a warmer，more communicative atmosphere.For example，these children were encouraged to eat foods to get stronger or run faster，while heavier children experienced more negative pressures including threats and being made to feel guilty about those who can’t afford to eat three meals a day.If parents talked constantly throughout the meal about food，and lectured the children about homework or attempted to control what the children ate，the youngsters were also more likely to be heavy.Also，the researchers found heavier children tended to have shorter meals. In the meantime，the current data suggests that simply sitting down at the same table at the same time isn’t enough to influence obesity.And it’s up to family doctors to help families understand how to take full advantage of having a meal together. 1.What were sorted into two groups by Berge’s team? A.Foods served at three meals. B.Conversations happening during dinner. C.Features of family meals influencing weight. D.Feelings coming out of discussions about food. √ 推理判断题。根据第二段中“Berge’s team sorted the interactions occurring at the table into two broad groups—those relating to the emotional atmosphere at the meal...and those involving food specially...”可知，Berge的团队探究了经常和家人一起吃饭的孩子患肥胖症的概率更低的原因，根据餐桌上的互动情况将影响孩子体重的家庭用餐特点分为两种类型。故选C。 解析 2.What did parents with non-obese children do at the table? A.They told the children to eat to get healthy. B.They talked with the children about homework. C.They lectured the children about treasuring food. D.They asked the children to finish meals quickly. √ 细节理解题。根据第三段中“these children were encouraged to eat foods to get stronger or run faster”可知，不超重的孩子的父母在餐桌上鼓励孩子吃东西以变得更强壮、跑得更快。故选A。 解析 3.What kind of tip should family doctors offer families? A.Cooking delicious meals. B.Dieting in a healthy manner. C.Making good use of dining together. D.Creating shared conversation topics. √ 细节理解题。根据最后一段中“And it’s up to family doctors to help families understand how to take full advantage of having a meal together.”可知，家庭医生应该建议家庭充分利用一起吃饭的机会。故选C。 解析 4.What is the best title for the text? A.How Obesity Spreads Across Family Members B.Why More Children Are Becoming Overweight C.Why Parents Should Eat Together with Children D.How Dining with Parents Affects Obesity in Kids √ 标题归纳题。通读全文可知，文章主要介绍了一项探讨与家人一起吃饭对儿童体重的影响的研究，具体呈现了影响的方式。因此，D项“与父母共进晚餐如何影响孩子的肥胖”是最佳标题。故选D。 解析 B(此篇精读) (2025·湖南益阳高二上期末) We all know how it is：you finish a long day at work，head home，relax for a few moments，and then haul yourself back up to start dinner.For most of us that will up the time around 7 p.m.at the absolute earliest，but according to a new study，that is simply too late in the day if you are looking to lose weight. 语篇解读　这是一篇说明文。哈佛大学研究表明，提早吃晚饭更利于身体健康。 This Harvard University study actually suggests a time when most of us are still at work，making it almost harder to achieve for the average British.Still，the findings of the study are interesting，as it offers some insight into how the dieting process works in relation to our metabolism(新陈代谢). Here is everything you need to know about the new dinner time study. The Harvard study found 5 p.m.to be the most suitable time for dinner because of the way the body’s metabolism functions for the average person.One of the main reasons is that eating dinner earlier will stop you from getting hungry throughout the day and turning to snacking. The study also found that people who ate food later in the day burned their calories more slowly as their metabolism is slower during later hours.This would mean the weight gained would take longer to shift，helping promote fat growth as a result. As this study is new，it is once again breaking new ground in the ever-evolving，ever-changing conversation surrounding food and weight. One such person is a functional nutritionist and CEO of Flo Living Alisa Vitti，who explained that the later you eat，the harder it is for your food to digest. “Any time between 6－8 p.m.is an ideal dinner time，” another person Tracy said，adding “That’s because it gives the average person enough time to digest before hitting the hay around 10 or 11 p.m.” Naturally，it ultimately comes down to the individual depending on whether or not you are up early or rise later in the day. 5.What is the function of paragraph 1? A.To tell a truth. B.To introduce the topic. C.To provide an example. D.To describe a phenomenon. 推理判断题。由第一段中“For most of us that will up the time around 7 p.m.at the absolute earliest，but according to a new study，that is simply too late in the day if you are looking to lose weight.”以及后文可知，第一段的作用是引出后文话题——提早吃晚饭更利于身体健康。故选B。 解析 √ 6.What did the Harvard study find? A.Everyone must have their dinner at 5 p.m. B.Eating dinner earlier will make people have snacks. C.The later people eat food，the less weight they will get. D.People burn their calories faster when eating dinner earlier. √ 推理判断题。由第四段中“The study also found that people who ate food later in the day burned their calories more slowly as their metabolism is slower during later hours.”可知，提早吃晚饭有助于燃烧卡路里。故选D。 解析 7.What is Alisa Vitti’s attitude towards the study? A.Disapproving. B.Objective. C.Supportive. D.Indifferent. 观点态度题。由倒数第三段“One such person is a functional nutritionist and CEO of Flo Living Alisa Vitti，who explained that the later you eat，the harder it is for your food to digest.”可知，Alisa Vitti是支持这项研究结果的。故选C。 解析 √ 8.What does the text mainly talk about? A.The best time to go to bed. B.Different ways to lose weight. C.Different opinions about having dinner. D.A new study about the best time to have dinner. √ 主旨大意题。通读全文，尤其根据第二段中“Still，the findings of the study are interesting，as it offers some insight into how the dieting process works in relation to our metabolism(新陈代谢).”和第四段内容可知，文章主要讲了哈佛大学的一项关于吃晚饭的最佳时间的研究。故选D。 解析 1.in relation to与……有关 2.functional(派)＝function＋al adj.功能的，职能的 3.nutrition n.营养，滋养→nutritionist n.营养学家→nutritional adj.营养(物)的→nutritious adj.有营养的，营养丰富的 4.come down to可归结为，可归纳为 词汇积累 1.This Harvard University study actually suggests a time when most of us are still at work，making it almost harder to achieve for the average British. 分析：此句为复合句。when引导定语从句，先行词为time，when在从句中作时间状语。it作形式宾语，后面的to do不定式为真正的宾语。 翻译：哈佛大学的这项研究实际上表明，这个时候我们大多数人都还在工作，这使得普通英国人几乎很难达到这个目标。 句式分析 2.The study also found that people who ate food later in the day burned their calories more slowly as their metabolism is slower during later hours. 分析：此句为复合句。that引导宾语从句，作动词found的宾语。who引导定语从句，先行词为people，who在从句中作主语。as引导原因状语从句，意为“因为”。 翻译：研究还发现，晚些时候吃饭的人燃烧卡路里的速度更慢，因为他们在晚些时候的新陈代谢更慢。 (2025·湖北高二上期末) Why Is Eating Colourful Food Good for You? Most of us are faced with the same choice numerous times a day：what to eat. 语篇解读　本文是一篇说明文。文章主要介绍了为什么吃五颜六色的食物对我们的健康有益。 Ⅳ.七选五阅读 A.Food is very complex. B.A varied diet is packed with different vegetables. C.It could be really tricky to get every colour every day. D.But how do we know we’re getting enough nutrients? E.Different coloured foods come with different benefits. F.However，is colour the best guide to getting all the nutrients? G.And one way to do this is by eating all the colours of the rainbow.
