第1讲 描述运动的基本概念

之间为被动关系,因此用过去完成时的被动语态。故填had been restored。
2.根据语境可知,修复项目是过去的事情,由Before the project可知,设空处的动作发生在“过去的过
去”,要用过去完成时,且rare cultural relics 和所给提示词document之间是被动关系,因此用过去完成时
的被动语态。故填had been documented。
3.根据Before the project和and 可知,第三空和第二空一样,也要用过去完成时,且 convincing evidence 和
所给提示词collect 之间是被动关系,因此用过去完成时的被动语态。故填had been collected。

Ⅰ.阅读理解
[2026河北沧县中学月考]
Constantly reaching for our phones upon waking, standing at the same point on the station platform—we all
have habits that shape our lives. But objectively speaking, you may underestimate the power habits have in
your life. A new study finds most daily actions are done on autopilot.
Habitual behaviour is made up of the things that we do without thinking, prompted(引起) by our environ-
ment and learned through repeated action. Meeting a familiar situation can cause a learned association,
which in turn prompts a non-conscious(无意识的) desire to act. The sound of your alarm clock, for exam-
ple, may be enough to prompt you to reach for your phone, without consciously deciding to.
第1讲 描述运动的基本概念
How much of our day-to-day lives are shaped by habit? To answer the question, we recruited(招募) 105
people, aged 18-73, and sent messages to their phones six times a day over one week. Each message asked
four questions: what were they doing when we interrupted them? To what extent was that action begun
without conscious thought? To what extent was it performed automatically? And how much had they wanted
to do it? The most commonly reported behaviour types were working, studying, or using a screen-based de-
vice. More importantly, 65% of all actions were done out of habit.
However, this does not mean that we simply act mindlessly, without awareness or free will. Around one
in three actions in our study were intentional but not habitual. People had consciously chosen to do them,
probably because the action or setting was unfamiliar, or because their habits were not strong enough to gen-
erate influence. Crucially, 76% of all actions were things people intended to do. Habits develop when we re-
第1讲 描述运动的基本概念
peatedly do things in certain settings. Several studies suggest that, with once-daily repetition, it takes around
two months to form a habit. The time required for habit formation ranges considerably, though. One 2021
study found habit formation to take anywhere from 4 to 335 days.
Therefore, habits aren't free will's enemy—they ease life. Problems arise when habits conflict with
goals. When such conflicts occur, understanding how to change those habits becomes crucial.

第1讲 描述运动的基本概念
语篇解读 本文是一篇说明文。文章主要介绍了习惯对人们日常生活的影响、习惯是如何形成的,以
及当习惯与目标发生冲突时,如何改变这些习惯变得至关重要。
【高频词汇】 1.association n.联想,联系;关联;协会 2.conscious adj.有意识的 consciously adv.有意
识地 3.generate v.产生 4.crucial adj.关键的,至关重要的 crucially adv.至关重要地,关键地 5.re-

2.will熟义:modal v.将要 生义:n.意愿
3.break熟义:v.打碎 生义:v.戒除(习惯)
【差距词汇】 underestimate v.低估
第1讲 描述运动的基本概念
1.D 推理判断题。第一段在列出“醒来就习惯性地去拿手机、在站台固定站位”两个日常例子后,
用表示转折的“But”引出核心观点“you may underestimate the power habits have in your life(你可能
低估了习惯在你生活中的影响力)”,最后以“A new study finds most daily actions are done on autopilot.
(一项新研究发现,大多数日常行为都是下意识自动完成的。)”引出对“习惯行为”的深入探讨。因
此,第一段的目的是引出本文话题“the habitual behaviour”。故选D。
类比启发 首段是“举例→提出观点→铺垫研究”的逻辑,需注意区分“举例内容”和“核心观
点”,避免被具体例子误导,并重点关注表示转折的连词“But”后的句子。
第1讲 描述运动的基本概念
2.B 细节理解题。由第四段第五句“Habits develop when we repeatedly do things in certain settings.(当
我们在特定的环境中反复做某事时,习惯就会形成。)”可知,B项“Through repeated actions in stable
contexts.(通过在稳定环境中反复践行。)”符合题意,其中“repeated actions”对应“repeatedly do
things”,“stable contexts”对应“certain settings”。故选B。
3.D 推理判断题。通读第三段可知,该段主要介绍了研究的对象(105 people, aged 18-73)、过程和方
法(sent messages to their phones six times a day over one week. Each message asked four questions...)与调
研结果(The most commonly reported behaviour types...habit.)。由此可推测,研究人员给参与者的手机发
送信息是为了收集关于他们行为的数据。故选D。
第1讲 描述运动的基本概念
4.A 推理判断题。由文章最后一句“When such conflicts occur...crucial.(当那样的冲突发生时,了解如
何改变那些习惯变得至关重要。)”可推测,接下来可能会讨论戒除那些习惯的方法,A项“Ways to
break those habits.(戒除那些习惯的方法)”与文章话题一致,且符合行文逻辑“冲突出现→需要改变习
惯→陈述方法”。故选A。
类比启发 下文推断题考查学生根据文本信息,推断文章后续发展的能力。考生须关注文章最后一
句内容或最后几句的话题,选出话题一致、逻辑顺畅的选项。

Sleep Procrastination: Why You Can't Just Go to Bed
Have you ever told yourself, “Just five more minutes” before bed, only to find yourself still awake
an hour later? If so, you're not alone. Sleep procrastination—delaying bedtime despite knowing the conse-
quences—isn't unusual. Instead, it's a constant part of many people's nightly routines.
1 The truth is, sleep procrastination is more complex than poor time management. Both psycholog-
ical and emotional factors make it difficult to simply go to bed earlier.
During the day, we are faced with responsibilities: school, homework, and endless tasks. At night, we
finally feel in control of our time. 2 We seek distractions like scrolling through social media or playing
第1讲 描述运动的基本概念
games. These might feel like stress relief, but staying up late leaves you exhausted the next day.
However, the problem is that most of these activities are designed to keep us addicted. Social media
apps and video platforms trigger dopamine(多巴胺) releases, making it hard to stop. 3 It's a vicious cy-
cle.
But it's one we can break. First, we need to find moments of pleasure during the day, so we don't feel
the need to steal time at night. Furthermore, a friendly sleeping environment is also crucial. 4 Avoid
overstimulating activities like intense gaming or action movies right before bed.
Sleep procrastination may seem like a small win. 5 So the next time you think, “Just five more
minutes,” choose self-care. Your future self will be grateful.
第1讲 描述运动的基本概念
A.But the real victory is waking up refreshed.
B.Stop blaming yourself for a simple lack of self-discipline.
C.This cycle can be broken with strong determination alone.
D.Instead of resting, we often stay up late as a form of rebellion.
E.Therefore, creating a consistent sleep schedule is the most effective solution.
F.Dim the lights, avoid screens, and wind down with a book or a calming activity.
G.Our brains seek the next small hit of pleasure, even when our bodies are begging for sleep.

第1讲 描述运动的基本概念
语篇解读 本文是一篇说明文。文章介绍了睡眠拖延这一常见现象,分析其并非因单纯时间管理不当
或缺乏自律,而是受心理、情绪因素及娱乐产品成瘾性影响,并给出了戒除睡眠拖延的具体方法。
【高频词汇】 1.delay v.推迟 2.complex adj.复杂的 3.psychological adj.心理的 4.in control of掌
控,管理
5.release n.& v.释放 6.intense adj.激烈的 7.refreshed adj.清爽的;精神振作的 8.blame v.责怪,指责
【差距词汇】 1.vicious adj.恶劣的,严重的
2.overstimulating adj.过度刺激的
1.根据下文“The truth is, sleep procrastination is more complex than poor time management.(事实上,睡眠
拖延比糟糕的时间管理更复杂。)”可知,空处需否定“睡眠拖延是简单问题”的认知,B项(别再因为
单纯缺乏自律而自责了。)既呼应了人们对睡眠拖延的常见误解,又引出下文对复杂原因的分析,符合
语境,连接了现象与本质。故选B。
第1讲 描述运动的基本概念
学科思维 “The truth is”“The fact is that”“In reality/fact”等常用来提醒读者,接下来要说的内
容可能与之前提到的信息有所不同,或者是对之前信息的一个纠正或补充,表示“转折和强调”的逻辑
关系,通常起到承上启下、澄清事实的作用。
第1讲 描述运动的基本概念
2.前文指出“晚上我们终于觉得能掌控自己的时间”,后面说明“通过浏览社交媒体、玩游戏来分心,
看似减压,实则熬夜会导致第二天疲惫”。D项(我们常常把熬夜作为一种反抗形式,而非休息。)解释
了“掌控时间”的具体表现——反抗白天的责任束缚,通过熬夜夺回时间自主权,与后文“寻求分心”
形成因果逻辑。故选D。
易错归因 该题易只关注到后文功能而错选G。文章整体为“心理→行为→成瘾”的层层递进逻
辑,分析睡眠拖延。G项(即使在身体渴望睡眠时,大脑仍在追求下一次小小的愉悦感。)对应第四段语
境,而且G项没有衔接前文“掌控时间”,无法解释“为什么掌控时间后,会选择熬夜而非休息”,与前
后文逻辑脱节。故排除G。
第1讲 描述运动的基本概念
3.上文指出“社交媒体应用软件和视频平台触发多巴胺释放,让人难以停止”,下文总结“这是一个恶
性循环”。G项(即使在身体渴望睡眠时,大脑仍在追求下一次小小的愉悦感。)具体解释了“多巴胺释
放”如何导致“大脑追求愉悦→不愿睡觉→身体疲惫→次日状态差”这一循环,却仍重复,完美呼应
“vicious cycle”。故选G。
4.前文提出“友好的睡眠环境至关重要”,后文补充“避免睡前过度刺激的活动”。F项(调暗灯光、
远离屏幕,通过读书或舒缓活动放松。)是对“友好的睡眠环境”的具体建议,与后文“避免睡前过度
刺激的活动”形成并列关系,共同构成“改善睡眠的措施”。故选F。
5.根据上文“睡眠拖延看似是小胜利”和下文“选择自我关怀,未来的自己会感激这个决定”可知,A
项(但是真正的胜利是精神振作地醒来。)符合语境,通过“小胜利”与“真正的胜利”的对比,升华主
题——短期的熬夜快乐不如长期的清爽状态,呼应前文“熬夜导致疲惫”,并给出积极的行动导向。故
选A。

视。
14.D 根据下文的原因状语从句“as everything we do has rejection attached to it in some way”可知,我
