Ⅲ.主题语篇阅读(共8小题；每小题2.5分，满分20分) A (2025·河南南阳高二上期末) New research examined the video gaming habits of 160 public-school preteen students(70% from lower income households)，which represents an age group less studied in previous research.Participating students reported playing video games an average of 2.5 hours daily，with the group’s heaviest gamers putting in as much as 4.5 hours each day. The team looked for association between the students’ video game play and their performance on the standardized Cognitive Ability Test 7，known as CogAT，which evaluates language，quantitative and non-language skills.CogAT was chosen as a standard measure，in contrast to the teacher-reported grades or self-reported learning assessments that previous research projects relied on. Overall，neither time of play nor choice of video game types had obvious connections with the CogAT measures.That result showed no direct linkage between video game playing and cognitive performance，despite what had been assumed. But the study showed another side of the issue，too.Certain types of games described to help children build healthy cognitive skills also presented no measurable effects，in spite of the games’ marketing messages.The current study found that types of gameplay that seem to improve cognitive functions in young adults don’t have the same effect on much younger children，which was consistent with previous research. Does this mean the world can play on？Maybe，the research suggests.But the experts also warn that gaming time took the heaviest players away from other more productive activities—homework，to be specific—in a process psychologists call displacement.But even in those cases，the differences were slight between those participants’ and their peers’ CogAT measures of cognitive abilities. The study results show parents probably don’t have to worry so much about cognitive failures among video game-loving children，up to fifth grade.Reasonable amounts of video gaming should be OK，which will be delightful news for the kids.At least now we understand that finding balance in childhood development is the key，and there’s no need for us to over-worry about video gaming. 语篇解读　本文是一篇说明文。文章介绍了一项针对儿童的电子游戏习惯的新研究发现，游戏时间和游戏类型的选择都与认知能力测试结果没有明显的联系。 1．What can we learn from the new research mentioned in the text? A．Reported grades are the only standard measure. B．Poorer students are easier to have gaming addictions. C．Most preteen students play video games 4.5 hours daily. D．There is little direct relation between game play and CogAT results. 答案　D 解析　细节理解题。根据第三段“Overall，neither time of play nor choice of video game types had obvious connections with the CogAT measures.That result showed no direct linkage between video game playing and cognitive performance，despite what had been assumed.”可知，根据新研究，玩电子游戏与CogAT结果之间几乎没有直接关系。故选D。 2．Which statement did the previous study also indicate? A．Types of gameplay matter in children’s cognitive development. B．Young adults are more addictive to games. C．Parents haven’t taken games’ marketing messages seriously. D．Video games can have no effect on children’s cognitive functions. 答案　D 解析　细节理解题。根据第四段中“The current study found that types of gameplay that seem to improve cognitive functions in young adults don’t have the same effect on much younger children，which was consistent with previous research.”可知，之前的研究也表明，电子游戏对儿童的认知功能没有影响。故选D。 3．What does the underlined word “displacement” in paragraph 5 describe? A．The change of position of game players. B．The time usage of game players. C．The homework completion of game players. D．The social ranks of game players. 答案　B 解析　推理判断题。结合上文“But the experts also warn that gaming time took the heaviest players away from other more productive activities—homework，to be specific”可知，displacement这一过程指的是“重度玩家”将时间分配给玩游戏而非做家庭作业这样的更有成效的活动。因此，displacement描述的是游戏玩家的时间使用情况。故选B。 4．What does the author think is the most important for children’s development? A．Interest. B．Imagination. C．Balance. D．Intelligence. 答案　C 解析　细节理解题。根据最后一段中“At least now we understand that finding balance in childhood development is the key，and there’s no need for us to over-worry about video gaming.”可知，作者认为平衡对儿童发展是最重要的。故选C。 B(此篇精读) For the Greek philosopher Celsus，red wine could be used to treat endless diseases，from tiredness to fever and coughs.But despite its convenient healing powers，the grape，he told his faithful readers，could bring about headaches.Now，researchers believe they have found the reason why red wine causes such headaches. “We think we are finally on the right track toward explaining this old mystery，” said Morris Levin，the director of the Headache Center at the University of California，San Francisco.“The next step is to test it scientifically on people who develop these headaches.” Red wine headaches are different from the morning-after hangover(宿醉)．Rather than coming on after a long session，they can strike 30 minutes after drinking only one small glass. The researchers ran lab tests on more than a dozen chemicals in red wine.One stood out.Quercetin(槲皮素)，found almost only in red wine，turned out to be particularly effective at blocking the enzyme(酶) that breaks down alcohol.This could be key to solving the mystery.With the important enzyme suppressed，alcohol builds up in the bloodstream.At high levels，this causes headaches，red faces and sweating. According to the researchers，when some people drink red wine with even small amounts of quercetin，they can develop a headache.Why some are more affected than others is unclear.The team now hopes to find out the effects of red wines with different quercetin levels. Grapes make quercetin in response to sunlight，so grapes grown in plenty of sunlight can have five times more quercetin than other reds.Processes like fining and ageing also affect quercetin levels.“It will be potentially very helpful for people who drink red wine to be able to choose wines less likely to cause headaches，” Levin said.“Also，winemakers may use our findings to reduce quercetin in their wines.” 语篇解读　这是一篇说明文。文章主要说明了研究人员认为红葡萄酒中的槲皮素可能是红葡萄酒导致头痛的原因，并解释了研究开展的经过。 5．In what way are red wine headaches different from those of hangover? A．They come on after a long time. B．They affect wine drinkers equally. C．They occur within a short time. D．They produce different symptoms. 答案　C 解析　细节理解题。根据第二段中的“Red wine headaches are different from the morning-after hangover(宿醉)．Rather than coming on after a long session，they can strike 30 minutes after drinking only one small glass.”可知，红葡萄酒的头痛效应与宿醉头痛不同的地方在于，红葡萄酒引起的头痛是在短时间内发作。故选C。 6．What does the underlined word “suppressed” in paragraph 3 probably mean? A．Blocked. B．Supplied. C．Increased. D．Supported. 答案　A 解析　词义猜测题。根据画线词所在句上文“Quercetin(槲皮素)，found almost only in red wine，turned out to be particularly effective at blocking the enzyme(酶) that breaks down alcohol.This could be key to solving the mystery.”可知，红葡萄酒中含有的槲皮素可以阻止分解酒精的酶，这导致这种重要的酶被抑制，酒精在血液中积累。故画线词“suppressed”意为“抑制”。故选A。 7．What is the team going to focus on next? A．The cure for wine headaches. B．The reduction of quercetin. C．The effects of quercetin amount. D．The way to solve hangover. 答案　C 解析　细节理解题。根据倒数第二段中的“The team now hopes to find out the effects of red wines with different quercetin levels.”可知，该团队下一步研究的重点是槲皮素用量的影响。故选C。 8．What is the last paragraph mainly about? A．The background of the research. B．The importance of processes. C．The way to produce quercetin. D．The applications of the findings. 答案　D 解析　段落大意题。根据最后一段中的“‘It will be potentially very helpful for people who drink red wine to be able to choose wines less likely to cause headaches，’ Levin said.‘Also，winemakers may use our findings to reduce quercetin in their wines.’”可知，最后一段主要讲研究结果的应用。故选D。 [词汇积累] 1．tiredness(派)＝tired＋ness n．疲劳，疲倦 2．on the right track思路正确；做法对路 3．stand out突出，脱颖而出 4．build up增强；积累；逐步发展 5．in response to作为对……的回应 [句式分析] 1．Now，researchers believe they have found the reason why red wine causes such headaches. 分析：此句为复合句。believe后为省略引导词that的宾语从句；why引导定语从句，修饰the reason。 翻译：现在，研究人员认为他们已经找到了红葡萄酒导致头痛的原因。 2．It will be potentially very helpful for people who drink red wine to be able to choose wines less likely to cause headaches. 分析：此句为复合句。it是形式主语，真正的主语为to choose...；其中people为先行词，who引导定语从句。 翻译：对于喝红葡萄酒的人来说，能够选择不太可能引起头痛的葡萄酒是很有帮助的。 Ⅳ.七选五阅读(共5小题；每小题2.5分，满分12.5分) (2025·浙江杭州高二上期末) Have you ever complained that there just aren’t enough hours in a day? Do you usually find yourself falling short on time in completing assigned tasks？ 1 No matter how hard I tried，tasks just kept piling up towards the end every day and it became extremely difficult to stay productive.In spite of trying all kinds of free and paid to-do apps，nothing helped. That didn’t change until I discovered the time management technique called Time Blocking.Since then，I have been able to transform my daily schedule for the better with the help of Time Blocking. 2 It is a simple time management technique where you schedule your day such that it is divided into time blocks that are dedicated to specific tasks or groups of tasks. 3 Imagine that you have a dozen or so tasks that you want to finish working on tomorrow.You open your to-do app of choice and neatly list down everything that you plan to do，and then plot some important meetings and reminders in your calendar app. 4 The more specific you are about the task，the more focused and productive you will be and thus，more productive. 5 It not only makes your to-do list more manageable，but it also gives you more control over your day and helps you prioritize your tasks.It also improves your focus and helps get rid of procrastination(拖延症)，as it allows you to focus on one project at a time. A．So what is it exactly? B．Is everyone interested in it? C．I used to be in the same boat. D．The benefits of Time Blocking are substantial. E．Let’s further explain the concept in another way. F．You’ll encounter countless questions like these in your life. G．You’ll need to be very specific about the time and what you’re planning to do. 语篇解读　本文是一篇说明文。文章介绍了一种时间管理技巧——时间模块管理Time Blocking。 1．答案　C 解析　作者在前文向读者提出两个关于时间分配方面的问题，后文讲述自己在时间分配上的处境，C项“I used to be in the same boat.”符合语境，承上启下。故选C。 2．答案　A 解析　前文“That didn’t change...with the help of Time Blocking.”引入“时间模块管理”这一概念，后文“It is a simple time management technique...”开始具体介绍这一概念，A项“So what is it exactly？”符合语境，引出后文内容，且其中的“it”指代前文的“Time Blocking”。故选A。 3．答案　E 解析　前文具体介绍了Time Blocking这一概念，后文“Imagine that you have a dozen...in your calendar app.”设想了具体应用该概念的情景，E项“Let’s further explain the concept in another way.”符合语境，承上启下，自然过渡到后文的具体解释。故选E。 4．答案　G 解析　后文“The more specific you are about the task，the more focused and productive you will be and thus，more productive.”说明了对待任务的具体程度和注意力、效率的关系，G项“You’ll need to be very specific about the time and what you’re planning to do.”符合语境，引出后文，其中的“specific”与后文内容呼应。故选G。 5．答案　D 解析　空处位于段首，是段落主旨句，需概括段落内容。后文“It not only makes your to-do list...as it allows you to focus on one project at a time.”具体介绍了时间模块管理这一技巧的好处，D项“The benefits of Time Blocking are substantial.”符合语境，可概括段落内容。故选D。 Ⅴ.语法填空(共10小题；每小题1.5分，满分15分) (2025·江苏常州高二上期末) A new marketing trend has arisen in China，driving crowds to places 1._______(recommend) on social media by young adventurers.Armed with just a smartphone and 2.________________ eye for storytelling，the young are transforming lesser-known cities into must-see attractions.A group of university students，now known as the “Night Riding Army”，3.________________(cycle) 50 kilometres to Kaifeng.Their recordings went viral.
