UNIT 9　限时规范练(A) (限时30分钟) 　　　　　　　　　　　　　　　　 Ⅰ.阅读理解 A A Harvard nutritionist shares 4 brain foods that will help your kids stay “sharp and focused”． Homemade hummus Legumes(豆类) are healthy，plant­based sources of iron，zinc，protein，omega­3s and fiber，benefiting brain development.Homemade hummus is a good way to include legumes into your child's diet.It can be served in so many ways，such as a dip paired with apple slices，carrot sticks or sugar snap peas.Adding some color to your hummus can make it more appealing to kids.Think: a bright orange carrot hummus topped with a monster face made out of vegetables. Salmon Introducing your child to fish at a young age can increase their likelihood of enjoying it and eating low­fat，vitamin­rich proteins for the rest of their life.Salmon is soft and mild enough for young children，and is also a good source of vitamin B12 and omega­3s，which promote healthy brain development and happier moods. Eggs Whole eggs are an excellent source of brain­boosting vitamins A，D and B12，along with choline(胆碱).Choline is especially important for young children，as it has been shown to improve brain development and long­term memory.One study found that pastured eggs can have twice as much vitamin E and almost three times as many omega­3s as caged eggs. Meatballs Add some powerful plant­based fiber and nutritious vegetables to your child's diet through meatballs.Start with a base of beans or ground turkey.Then add grated celery and flax seeds full of omega­3s.Of course，don't forget your favourite spices.Cook and serve. 1．Which food can enhance healthy brain development and happier moods? A．Homemade hummus. B．Salmon. C．Eggs. D．Meatballs. 2．What do these four foods have in common? A．They all have plant fibers. B．They all have low fat. C．They all have vitamin B12. D．They all have omega­3s. 3．Who is this passage targeted at? A．Those who want to lose weight. B．Those who desire to put on weight. C.Those who intend their kids to be more focused. D．Those who expect their students to be more hard­working. 【语篇解读】本文是一篇应用文。一位营养学家分享了4种让孩子保持“敏锐和专注”的健脑食物。 1．B　[解析]细节理解题。根据Salmon部分中的“Salmon is soft and mild enough ...which promote healthy brain development and happier moods.”可知，鲑鱼有助于大脑健康发育和心情愉快。故选B。 2．D　[解析]细节理解题。根据Homemade hummus部分中的“Legumes are healthy，plant­based sources of iron，zinc，protein，omega­3s and fiber”、Salmon部分中的“Salmon is soft and mild enough for young children，and is also a good source of vitamin B12 and omega­3s ”、Eggs部分中的“One study found that pastured eggs can have twice as much vitamin E and almost three times as many omega­3s as caged eggs.”和Meatballs部分中的“Then add grated celery and flax seeds full of omega­3s.”可知，四种食物中都含有omega­3s。故选D。 3．C　[解析]推理判断题。根据第一段可推知，这篇文章的目标读者是那些想让孩子更专注的人。故选C。 B (2025·湖北武昌区模拟)Growing up，Maitri Wadher，a left­hander，has struggled to cope in a world made for right­handed people.From school desks to spiral notebooks that stop the natural flow of writing，Maitri has faced tough challenges from a young age.“My mother used to tie my left hand and make me eat with my right until a doctor warned that this could greatly affect my growth and confidence，” Maitri says.

Starting The Left Out Store wasn't in the cards for Maitri for a very long time.The idea for The Left Out Store came to Maitri in just 20 minutes during a festival at St.Joseph's Institute of Management，where she was a post­graduate student.She presented the rough idea to judges who later became sponsors，and they enthusiastically supported it.This encouragement gave her the push to make it a reality.She eventually make it her market research project to test the waters and explore the potential market.

A new study in the journal PLOS Biology finds that bumblebees can learn certain behaviors from each other，suggesting these social insects have a capacity for what we humans call “culture”． In the past couple of decades，a growing body of evidence has shown that animals like chimps and birds show behaviors of learning.If what they learn lasts for a long time，it turns into a tradition.And culture is made up of multiple traditions.“Bumblebees，though，have some of the most complex behavioral abilities，nobody has really thought to look at culture in such insects and people generally assume they're mostly driven by inborn factors instead，” says Alice Bridges，a behavioral ecologist at Anglia Ruskin University in England. To prove them wrong，Bridges built a puzzle box，whose base held the reward: a drop of super sweet sugar water.The box was designed with a rotating(旋转) top that can be rotated by pushing either on a red tab clockwise or a blue tab anti­clockwise.Some bees were trained to push the red tab to get the sugar water while others pushed the blue one.Then，these tutor bees were placed inside different colonies(蜂群)，along with the puzzle boxes. The experiment ultimately played itself out.In colonies where the tutor bee had originally learned to push the red tab，the other bees in the colony usually pushed the red tab.In colonies where the tutor bee was trained to push the blue tab，their fellow bees also tended to do the same.In contrast，in the control groups without tutors，the bees sometimes learned how to open the boxes，but most of them would do it once or twice and then never again.“They perhaps hadn't quite made the link between their behavior and the reward，” Bridges supposes. “Many of us consider ourselves to be rather special ...because we have culture，we can learn and we're social，” Bridges says.“But now it turns out that even the bee also has culture，which is an uncomfortable truth: human culture，once thought unique，does not emerge ‘out of the blue’ but has obviously built on deep evolutionary foundations.” 1．What is people's common attitude to bumblebees having culture? A．Positive. B．Indifferent. C．Interested. D．Doubtful. 2．Why does Bridges place trained bees inside different colonies? A.To test their learning capability in new settings. B．To see if they will spread the secret of the boxes. C．To evaluate their ruling power in various groups. D．To observe if they will share their food with peers. 3．What does the last paragraph mainly talk about concerning the study? A．Its appeal to the public. B．Implications on cultural origins. C．Its practical application. D．Suggestions for future directions. 4．Which of the following can be the best title for the text? A．Human Culture Is Losing Its Uniqueness B．Bee's Behavior Builds on Biological Factors C．Culture May Be Present Among Bumblebees D．Animals' Evolution May Start from Colonies 【语篇解读】本文是一篇说明文。文章介绍了一项新的研究发现：大黄蜂具有人类所说的“文化”的能力。 1．D　[解析]推理判断题。根据第三段中的“Bumblebees，though，have some of the most complex behavioral abilities，nobody has really thought to look at culture in such insects and people generally assume they're mostly driven by inborn factors instead”可知，人们通常认为大黄蜂的文化是由先天因素驱动的，对大黄蜂具有文化持有怀疑的态度。故选D。 2．B　[解析]推理判断题。根据第五段中的“The experiment ultimately played itself out ... their fellow bees also tended to do the same.”可推知，Bridges把经过训练的大黄蜂放在不同的蜂群里，是为了观察大黄蜂是否会传播盒子里的秘密，将自己的行为传播给同伴。故选B。 3．B　[解析]主旨大意题。根据最后一段中的“But now it turns out that even the bee also has culture，which is an uncomfortable truth: human culture，once thought unique，does not emerge ‘out of the blue’ but has obviously built on deep evolutionary foundations.”可知，本段主要介绍了曾经被认为是独一无二的文化并不是突然出现，而是逐渐进化而来的。因此，本段主要谈论了这项研究对于文化起源的影响。故选B。 4．C　[解析]标题概括题。通读全文可知，研究发现，大黄蜂具有人类所说的“文化”的能力，所以C项“文化可能存在于大黄蜂中”适合作文章标题。故选C。 B We've had waves of panic around technology for decades，whether it is comic books or video games.Now it happens to be social media.And the fact of the matter is that parents and teachers，who are trying to raise their kids in the face of these panics，are being poorly served by the government when it comes to getting meaningful advice. It's not that social media is good or bad for people.It's that the science of social media and mental health is broken.We need to do research，but we shouldn't be approaching it from the perspective that the world is ending.We need to be curious and open to the possibility of its effects，positive and negative. The danger for policymakers or parents is that if you pretend that social media is a problem，without having evidence，and you take steps to regulate it，the intervention(妨碍) could end up being really bad for young people.You might be taking away a lifeline for vulnerable(脆弱的) kids or free them of their human right to play，which is morally reprehensible(受谴责的) at the best of times，let alone during a pandemic. So that's why I'm not going to tell you that I know social media is bad.It's perfectly reasonable for parents and teachers to be concerned about social media，but it's unavoidable and young people are going to encounter it sooner or later.So what would you rather do：keep them in the dark and leave them ill­equipped to deal with it or let them learn about social media with your help and support？It's a little like learning to ride a bike.Bikes can be huge fun to ride，but you can also hurt yourself on them，which is why you don't just give your kid a bike and a helmet and wish them good luck.You help them learn to ride.Similarly，you're not asking your 14­year­old daughter to choose between telling you someone scary is messaging her or losing her phone.You need to treat it like anything else that can hurt you，but can also connect you. 5．What does this wave of panic refer to now according to the passage? A．Technology. B．Comic books. C．Video games. D．Social media. 6．What is the author's attitude towards the social media? A．Doubtful. B．Supportive. C．Neutral. D．Indifferent. 7．Which of the following statements does the author agree with? A.Parents should let children learn about social media on their own. B．The world is ending as a result of the negative effects of social media. C.Parents should be cautious when regulating children's using social media. D．Parents are advised not to give kids helmets when they learn to ride a bike. 8．What should we do to help our children? A．Give them some instructions. B．Ask the experts for help. C．Go to the special treatment center. D．Free them of their human right to play. 【语篇解读】本文是一篇议论文。文章主要介绍了社交媒体带来的科技恐慌。社交媒体无好坏之分，决策者和家长应该给予孩子正确的指导。 5．D　[解析]细节理解题。根据第一段前两句可知，目前新一波的科技恐慌来自社交媒体。故选D。 6．C　[解析]推理判断题。根据第二段中的“It's not that social media is good or bad for people.”及“We need to be curious and open to the possibility of its effects，positive and negative.”可知，作者对于社交媒体的态度是中立的。故选C。 7．C　[解析]推理判断题。根据第三段首句可知，作者认为家长应该谨慎干预孩子接触社交媒体。故选C。 8．A　[解析]细节理解题。根据最后一段中的“So what would you rather do ...or let them learn about social media with your help and support？It's a little like learning to ride a bike.”可知，面对社交媒体，我们应该给予孩子们指导，就像他们学习骑自行车一样。故选A。 Ⅱ.七选五阅读 Are you someone who easily gets tired and doesn't feel like doing anything? Do you label this kind of behavior as mere laziness？1.______ Feel disconnected from everything.

Meanwhile，Leticia Flores­Gonzalez，the mother of four­year­old Luna and her twin sister，Gianella，had no idea that such an effort was underway.It had been a hard year for Leticia and her girls.As the pandemic spread，the family felt lonely，scared，and isolated，with no relatives living nearby. On a particularly tough day last December，Leticia had come up with the idea of having the girls send letters to Santa by balloon.She told them that Santa would grab the balloons while he flew through the air on his sled.The twins were excited.Leticia helped them write down all the things that they dreamed Santa might bring them，and put the notes into Christmas red balloons.Then she took them outside to release their wishes to the universe on the chilly windy morning. 注意： 1．续写词数应为150左右； 2．请按如下格式在相应位置作答。 Paragraph 1： One day in January，a friend called Leticia and said，“Someone found Luna's balloon.” ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Paragraph 2： In April，Alvin and his wife made a trip to meet the girls. ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ [参考范文] Paragraph 1： One day in January，a friend called Leticia and said，“Someone found Luna's balloon.”Her jaw dropped.At her friend's urging，Leticia logged onto the social media website and saw Alvin's post.Then she saw that people from all over the world were asking if they，too，could be part of fulfilling the wish list.Leticia was deeply touched and gave Alvin a call.When Alvin told her how much it would mean to him to grant the girls' wishes，she agreed to let him bring them some gifts.Back in Louisiana，Alvin got busy collecting toys from his newfound social media community. Paragraph 2： In April，Alvin and his wife made a trip to meet the girls.That morning，just as chilly and windy as the day Luna and Gianella waved goodbye to their balloons，Alvin got out of the car in front of their house.He presented all the gifts to the twins，including a puppy.The girls cried with delight.Later，both families sat down together to share homemade breakfast.They all felt as if they had known each other forever.Having received so much generosity，Leticia and her girls expressed their gratitude and intended to pay it forward. 学科网（北京）股份有限公司 $$
