白题 Week 6 Friday 阅读理解 主题：最短的一天 难度：★★★★ 建议用时：9min 参考答案：P20 If July 22th this year felt like it's flying by,you can blame it on our spinning 夕干 planet:The day was indeed a fraction of a second shorter than normal.A shorter day is 读 not uncommon.On July 9,for example,the Earth's quick spin shortened the day by nearly 1.4 milliseconds.But recent headlines from all over the world have been hyping "freakishly short"days in July and August. Good data on the Earth's rotation goes back thousands of years,thanks to observations of solar eclipses in China.These days,researchers track the spinning of the globe by pointing radio telescopes at quasars,incredibly luminous cores of distant galaxies that are so far away,they act as fixed points in space. Generally speaking,over millions of years,the Earth's rotation has been decelerating,a trend that's expected to continue into the future.The main reason is the Moon.The Moon's gravitational pull on the Earth creates ocean tides,and a process called "tidal braking"gradually slows the Earth's spin. Researchers have started comparing the rotation of the Earth to the very accurate time standard provided by atomic clocks that measure the regular oscillations of atoms.In the past,the world's timekeepers have occasionally resorted to adding in some "leap seconds"-these extra seconds keep atomic time in sync with Earth's rotation as it slows.The last time an extra second was added to the clock was in 2016.The recent speedy spins of the Earth,however,raise the possibility of instituting "negative leap seconds",which is something that's never been done before. While the Moon has long been the major player in controlling the speed of the Earth's rotation,something else is stepping in.Climate change is melting ice at the poles and sending water down to the equator,slowing the rotation down.Some have calculated that in a worst-case scenario,climate change could eventually redistribute water in a way that would make the days milliseconds longer.But the question comes-who has been behind the climate change? 1.What does the underlined word "decelerating"in Paragraph 3 probably mean? A.Standing still.B.Speeding up. C.Slowing down. D.Became unstable. 2.How can negative leap seconds keep in step with Earth's rotation? A.By checking the atomic clocks. B.By adding another second. C.By testing oscillations of atoms. D.By taking away a second. 3.What does the underlined question in the last paragraph want to express? A.Moon affects water redistribution around the world. B.Humans might be the dominant driver of day length. C.Iceberg at the poles is the main reason of a longer day. D.Environment protection is already shortening the days. 4.What is the text mainly about? A.Prediction of variations in Earth's rotation.B.Earth's rotation will slow due to the Moon. C.Shorter days from Earth's rotation change.D.It's urgent to adjust how atomic clocks work. 074英语·0黑白题高二下 阅读理解+语法填空 Saturday Week 6 黑题 +读后续写 一、阅读理解 On a driveway with 15 vehicles per mile,one driver tapping the brakes can cause a persistent traffic jam.But actual ants-unlike cars-can avoid the stop-and-go traffic.Researchers are now studying these insects'cooperative strategies to learn how to program self-driving cars that don't jam up. Ants can maintain their flow even at high densities().So what's their secret?In a recent study,researchers recorded ants on trails and used traffic-engineering models to analyze their movement.They found that the ants don't jam because they travel in groups of 3 to 20 that move at nearly constant rates while keeping good distances between one another and they don't speed up to pass others. Human drivers at rush hour hardly tend to follow such rules."We're maximizing the interests of individuals.That is why,at a given point,you start to have a traffic jam,"says study co-author Nicola Pugno.In his vision of this future,autonomous vehicles would avoid traffic jams by prioritizing constant speeds and headways or by not passing others on the road. Like ants on a trail,which use scent()to control behavior while interacting with one another,the autonomous vehicle network would help cars keep constant speeds while collecting and sharing information."There is no leader,but this organization emerges anyway,"says Noa Pinter- Wollman,a behavioral scientist.And in both ant and vehicle traffic,this type of distributed system can be very strong and changeable. Still,ants can do a lot of things that cars-even self-driving ones-can't.Ants can make trails as wide as they like,unlike drivers stuck on highways.Plus,unlike cars,ants don't crash;they can literally walk over one another.Today's drivers can learn at least one thing from ants to avoid causing a traffic jam:by leaving room between their car and the one ahead of them,drivers can absorb a wave of braking in dense traffic conditions that would otherwise give rise to a traffic jam with no obvious cause. 1.Which is the contributing factor to ants'stable traffic at high densities? A.Slow speed. B.Varied trails. C.Sufficient space.D.Strict rules. 2.Which of the following is in line with Nicola Pugno's opinion about autonomous vehicles? A.They can lead to inefficient traffic flow. B.They may break the traffic rules at rush hour. C.They will drive more quickly than humans.D.They may be programmed to improve traffic. 3.What can we learn about autonomous vehicle network? A.It can keep the speed of vehicle under control.B.It can provide changeable routes. C.It can form a solid and flexible traffic system.D.It can use scent to communicate. 4.What does the passage mainly talk about? A.What ants do when facing traffic jams. B.How ants may save you from traffic jams. C.What we can benefit from ants'society.D.Why we should follow the traffic rules. 高二下英语·0黑白题075享平台”可知，lexicon指字符参考数据库。故选D。 4.B推理判断题。根据最后一段“these digital innovations exemplify China's integration of technology and cultural preservation,bridging ancient texts with modern tools to make Jiandu accessible to all'”可知，长沙博物馆使用AR图画书，甘肃 博物馆采用AI机器人，均为基于技术的教育方式的例证，旨在 强调科技在文化传承中的应用。故选B。 二、完形填空 【语篇解读】本文是一篇记叙文。文章讲述了作者决定去学习吉 他。但是，在经过一番努力之后，他发现他并不能在音乐上有所成 就，于是他决定写歌。最后，他终于取得了成功。 l.C由下文“Later,I watched a video of a street guitarist performing”可知，作者决定学习的是吉他。故选C。 2.B由下文“but where's the feeling”可知，同学评价作者的吉他 演奏缺乏感情，说明表演机械、无生气。故选B。 3.A由下文“I realized I'd been seeking technical perfection”可 知，同学承认追求技术上完美的作者演奏技巧完美，但就是缺 乏情感。故选A。 4.D由上文同学的评论“You played3,but where'sthe feeling?”可知，演奏技巧完美，但是缺乏情感，这些话触动了作 者，引出下文“Later,I watched a video of a street guitarist performing一his music5 like a conversation.”作者去观摩 真正有情感的吉他演奏是怎样的。故选D。 5.A对比上文“You played3,but where's the feeling?”作者 吉他演奏缺乏情感可知，街头吉他手的演奏充满了感情，音乐 像对话般自然流动。故选A。 6.B由上文语境可知，同学评价作者的吉他演奏缺乏感情，作者 观看视频中街头吉他手的演奏充满了感情，作者意识到自己是 在追求技术而非情感表达。故选B。 7.C gave up放弃，went on继续；turned to转向；dealt with处 理。由“Discouraged”和“writing my own songs”可知，作者意识 到自己的吉他演奏只有技巧没有感情，因沮丧放弃学习弹吉 他，转而写自己的歌。故选C。 8.A由下文“chords conflicted,lyrics wandered”可知，初次创作 和弦冲突、歌词散乱，说明一团糟。故选A。 9.C由上文“At a cafe open mic night,I froze halfway through my song.”可知，表演卡壳后，现场陷人沉默，与下文 “unbearable'”对应。故选C。 10.D由下文“He pointed to his heart..”可知，老人强调音乐是分 享内心，而不是为了避免错误。故选D。 ll.C由下文“I stopped comparing myself to others and began mixing my imperfections into my composition.”可知，听了老人 的话，作者心态和创作方式发生改变。故选C。 l2.B呼应上文“began mixing my imperfections into my composition'”讲作者创作原创作品。故选B。 l3.D由上文“began mixing my imperfections into my composition”可知，作者创作的歌曲仍有瑕疵，但观众仍享受， 体现接受不完美。故选D。 l4.B呼应上文“‘It's about10what's here..’He pointed to his heart..”讲老人建议作者音乐应发自内心。故选B。 l5.A由上文“‘It's about 10what's here..’He pointed to his heart.”可知，音乐应发自内心，再结合上文“began mixing my imperfections into my composition”可知，真正的音乐来自接受 自己独特的声音，允许自己犯错。故选A。 Friday 阅读理解 【语篇解读】本文是一篇说明文，围绕地球自转变化展开，介绍了地 球自转速度出现的短期加快、长期减慢的情况，阐述了影响地球自 转速度的因素（月球引力、气候变化等），以及由此引发的对原子钟 “负闰秒”设置的可能等内容。 1.C词义猜测题。根据第三段“The moon's gravitational pull on the Earth creates ocean tides,and a process called tidal braking'gradually slows the Earth's spin..”可知，月球引力等因 素使地球自转逐渐变慢，所以“decelerating”意思是“减速；变 慢”，与“Slowing down”同义。故选C。 2.D推理判断题。根据第四段“In the past,the world's 高二下 timekeepers have occasionally resorted to adding in some 'leap seconds'-these extra seconds keep atomic time in sync with Earth's rotation as it slows..”可知，过去地球自转变慢时通过添 加闰秒协调原子钟时间；而近期自转加快则可能需引入负闰 秒。逻辑上，负闰秒需通过减去一秒使原子钟时间与加快的自 转同步。故选D。 3.B推理判断题。根据最后一段可知，气候变化使两极冰融化， 导致自转变慢，随后反问“谁是气候变化的幕后推手？”。结合 前文climate change的主动描述及反问的隐含指向，暗示人类 活动可能是日长变化的主因。故选B。 4.C主旨大意题。文章开篇讲今年7月22日等日子因地球自 转加快而变短，接着介绍地球自转速度监测方式、长期减慢趋 势及影响因素（月球、气候变化等），还提到由此产生的“负闰 秒”可能，整体围绕地球自转变化导致白昼时间长短变化展开。 故选C。 Saturday 一、阅读理解 【语篇解读】本文是一篇说明文。文章主要介绍了研究人员通过研 究蚂蚁在高密度交通下的行为模式，探讨将这些策略应用于自动 驾驶汽车，以减少或避免交通拥堵。 1.C细节理解题。根据第二段“They found that the ants don't jam because they travel in groups of 3 to 20 that move at nearly constant rates while keeping good distances between one another and they don't speed up to pass others.”可知，蚂蚁在高密度下 交通稳定的原因是它们之间保持了足够的空间。故选C。 2.D细节理解题。根据第三段“In his vision of this future, autonomous vehicles would avoid traffic jams by prioritizing constant speeds and headways or by not passing others on the road.”可知，Nicola Pugno认为自动驾驶汽车可以通过编程来改 善交通状况，即自动驾驶汽车可能被编程以改善交通状况。故 选D。 3.C推理判断题。根据第四段“Like ants on a trail,which use scent.strong and changeable..”可知，自动驾驶汽车网络将帮 助汽车保持恒定速度，同时收集和共享信息，这种分布式系统 都非常强大且可变，可推理出自动驾驶汽车网络可以形成一个 坚固而灵活的交通系统。故选C。 4.B主旨大意题。通读全文，尤其是第一段“But actual ants- unlike cars-can avoid the stop-and-go traffic.Researchers are now studying these insects'cooperative strategies to learn how to program self-driving cars that don't jam up.”和最后一段 "Today's drivers can learn at least one thing from ants to avoid causing a traffic jam”可知，文章围绕蚂蚁的交通策略展开， 说明其对解决人类交通拥堵的启发，尤其是对自动驾驶汽车的 借鉴意义，因此，“蚂蚁如何帮你摆脱未来交通拥堵”可以概括 本文的主题。故选B。 二、语法填空 【语篇解读】本文是一篇说明文。文章介绍了中国科学院付巧妹团 队对新疆小河人墓葬中出土的世界上最古老奶酪进行基因分析的 情况，揭示了青铜时代的文化交流等信息。 1.undisturbed考查形容词。lay(处于…状态；躺；位于)是系 动词，提示词作表语，结合句意，用形容词undisturbed,意为“未 受惊扰的；未被打搅的”，表明主语the mummified remains的状 态。故填undisturbed.。 2.the oldest考查形容词最高级。根据in the world可知，空处应 填最高级，故填the oldest。 3.analysis考查名词。形容词后接名词，且first表示单数，故填 analysis. 4.exchanged考查时态。exchange是定语从句中的谓语动词，与 主语that(即先行词a rich Bronze Age culture)之间是主动关 系，根据语境可知，此处描述的是过去发生的事情，应用一般过 去时。故填exchanged。 5.imperfectly考查副词。空处修饰动词，应填副词。前文提到 研究团队发现了奶酪并分析了其来源，但此处用“though”(然 而)转折，说明“他们为什么随葬这些东西”这一问题尚未得到 完全解答。故填imperfectly。 6.by考查介词。此处需填入介词“by”,构成“by十动名词”结 学霸黑白题20
