Sensors implanted (植入) into his brain read his thoughts to control two robotic arms, which helps him to perform daily tasks. Now he can use one robotic arm to control a knife and the other a fork. 　　Modern technology can reach inside someone's head and pull out what he is thinking. Maybe he intends to move a robotic arm or type something on a computer screen. Such thought-controlled devices can help people who aren't able to move or perform different tasks and promote the well-being of the disabled. 　　Decoding (解码) thoughts usually requires placing sensors directly on or in someone's brain. Those im- planted sensors can catch the electrical signals passing between the person's brain cells, or neurons. 第1讲　描述运动的基本概念 Such signals carry messages that allow brains to think, feel and control the body. 　　Using brain implants, researchers have picked up electrical signals in the brain linked to certain words or letters. This has allowed brain implants to transform thoughts into text or speech on a computer. Likewise, brain implants have transformed imagined handwriting into text on a screen. Implanted sensors have even allowed scientists to turn the signals they caught that are associated with a song in someone's head into real music. 　　In a recent study, scientists decoded full stories from people's brains using MRI scans (磁共振成像扫 描). This did not require any brain implants. But building the thought decoder did require many hours of brain scans for each person. What's more, the system only worked on the person whose brain scans helped build it and only when that person was willing to have his mind read. 　　So devices that might let someone secretly read your mind from across the room are still a long, long 第1讲　描述运动的基本概念 way off. Still, it's clear that mind-reading technology is getting more advanced. As it does, scientists are thinking hard about what it would mean to live in a world where not even the inside of your head is com- pletely private. 1.What does the text begin with? A.A suggestion.　　　B.A comparison. C.An argument.　　　D.An example. 2.What is explained in the text? A.What principles a thought decoder should follow. B.How MRI monitors the work of the implanted sensors. C.What's used to catch signals passing through the brain. D.How robotic arms are designed to satisfy different needs. 第1讲　描述运动的基本概念 3.What is scientists' attitude towards the future of the technology discussed in the text? A.Concerned.　　　B.Confident. C.Doubtful.　　　D.Indifferent. 4.What can be a suitable title for the text? A.Mind Reading Is Stealing Our Privacy B.Mind Reading Is Hard, but Not Impossible C.Mind Reading—Good News for Musicians D.Mind Reading—a Brain-Scanning Technology 第1讲　描述运动的基本概念 语篇解读　本文是一篇说明文。文章主要说明了现代科技可以读取人的思想,从而操控机械臂来执行 不同的任务,改善残疾人的生活。 【高频词汇】    1.perform v.执行;做    2.device n.设备 3.promote v.促进;提升;晋升    4.transform v.使改变    5.be associated with 与……有关 【差距词汇】    1.well-being n.安康,幸福    2.neuron n.神经元   第1讲　描述运动的基本概念 1.D　推理判断题。根据第一段内容可知,Robert Chmielewski从十几岁起四肢瘫痪,植入他大脑的传感 器可以读取他的想法,从而控制两个机械臂,帮助他完成日常任务。因此,文章的开头是一个关于瘫痪病 人利用科技进行日常生活的例子。故选D。 2.C    细节理解题。第三段提到解码思想需要在大脑中植入传感器,这些传感器可以捕捉到在人的脑 细胞或者说神经元之间传递的电信号,这些信号携带的信息使大脑能够思考、感觉和控制身体。由此 可知,文章解释了被用来捕捉通过大脑的信号的工具。故选C。 3.A　推理判断题。根据最后一段最后一句“As it does, scientists are thinking hard about...where not even the inside of your head is completely private.”可知,科学家正在努力思考,生活在一个连大脑内部 都不完全私密的世界里意味着什么,由此可推知,科学家对文中讨论的技术的未来持担忧的态度。故选 A。 第1讲　描述运动的基本概念 4.B　主旨大意题。本文的篇章结构图如下: 由篇章结构图可知,文章主要介绍利用科技读取人的思想这一发明的应用场景、实现的方法及其引发的担忧,故B项“读心术很难,但并非不可能”最适合作为文章标题。故选B。 第1讲　描述运动的基本概念 Ⅳ.七选五   [2026辽宁大连期中] 　　Resistance training, also known as strength training, uses weights or resistance to strengthen or in- crease one's muscles. While many people associate such resistance with lifting free weights like dumbbells (哑铃) or doing machine-based exercises such as chest or leg presses, other forms of resistance also qualify. 　1　 　　There are various benefits of resistance training. Research shows that adding 30 minutes of strength training to your workout routine each week could add years to your life. 　2　 Strength training has also been shown to strengthen joints and bones affected by medical conditions, and help with weight man- agement goals since lifting weights improves metabolism (新陈代谢). 第1讲　描述运动的基本概念 　　　3　Monica Ciolino, a doctor of physical therapy at Washington University Physicians, says it's also been linked to protection against degeneration of parts of the hippocampus (海马体)—a grain structure important for learning and memory. “Additionally, strength training may be associated with lower rates of depression and anxiety,” says Ciolino. 　　Given so many advantages, why not try strength training?　4　 Daniel J McDonough, a researcher at the University of Minnesota's School of Public Health, says it's best to choose the type of resistance training that appeals most to you:weights, or resistance bands, and then learn a few simple techniques. For instance, you can lift weights at your local gym, or you can buy several dumbbells or kettlebells to lift at home.　5　“When you are using weights, a good rule of thumb is that your muscles should be tired at the end of a set,” says McDonough, though he stresses the importance of not lifting too much, too soon. “So, start with lighter loads and increase weight and repetitions over time.” 第1讲　描述运动的基本概念 A.How can we get started? B.What benefits can we get from strength training? C.Once you get going, you may want to branch out and add a barbell. D.This is partly because it can significantly improve your heart health. E.Moreover, strength training can improve mental health in several ways. F.You'd better do strength training with the help of a professional trainer regularly. G.Body-weight exercises like push-ups or sit-ups are other examples of resistance training. 1.______    2.______    3.______    4.______    5.______ 　C     　A     　E     　D     　G     第1讲　描述运动的基本概念 语篇解读　本文是一篇说明文。文章主要介绍了抗阻训练,包括其训练形式、益处等,最后就如何开始 进行抗阻训练给出了一些建议。 【高频词汇】    1.strength n.力量→strengthen v.加强,增强    2.associate...with...把……和……联系起来 3.management n.管理    4.be linked to 与……有关系    5.load n.负荷;工作量    6.regularly adv.定期 【差距词汇】    1.degeneration n.退化,恶化    2.a rule of thumb 经验法则,根据经验来看 1.空前一句提到了抗阻训练的一些形式,空处应列举其他形式的抗阻训练,G项“俯卧撑或仰卧起坐等 自身体重训练是抗阻训练的其他例子”符合文意,空前的“other forms of resistance”与G项中的“oth- er examples of resistance training”呼应,故选G。 2.空前一句提到每周在日常锻炼中增加30分钟的抗阻训练可以延长寿命,D项“其中一部分原因是它 可以显著改善你的心脏健康”解释为什么抗阻训练能延长寿命,符合文意,故选D。 3.空后两句提到抗阻训练与保护海马体的部分区域免于退化有关,也可能与较低的抑郁和焦虑发生率 第1讲　描述运动的基本概念 有关,因此,本段主要讲述抗阻训练对精神健康的好处,E项“此外,力量训练可以通过好几种方式改善精 神健康”符合文意,故选E。 4.空前提出问题——鉴于这么多优势,为什么不尝试力量训练呢?根据空后内容可知,研究人员建议,最 好选择最吸引你的抗阻训练类型,然后学习一些简单的技巧,因此,设空处应承上启下,询问如何开始抗 阻训练,A项“我们可以如何开始?”符合文意,故选A。 5.空前列举了一些训练方式,空处应提到进一步的训练方式,C项“一旦你开始了,你可能想朝新的方向 拓展并添加一个杠铃”符合文意,故选C。 第1讲　描述运动的基本概念 Ⅴ.读后续写   [2026湖北武汉二中月考] 　　阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 　　It was a cool fall morning, and the sun was just starting to rise,casting a warm light over the quiet neighborhood. For Alex, the high school junior with a deep passion for science, was filled with both excite- ment and nervousness. Today marked the final presentation of his science project, which he had been work- ing on for months. The topic was renewable energy, and Alex had built a model of a solar-powered car. He hoped it would help him win the regional science fair. 　　Alex checked his bag one last time: notes, sides, and the model car. Just as he was about to leave, his younger brother Axel came into the room with big, sorry-looking eyes. In his hand, he held a broken piece of 第1讲　描述运动的基本概念 the car's solar panel. “I'm really sorry, Alex!” Axel said in a very quiet voice, his head down because he felt guilty. “I was just so curious. I wanted to see how it worked, and I didn't mean to break it.” 　　Alex's eyes opened wide in shock, and his heart felt like it had dropped to the bottom of his stomach. The presentation was in a few hours, and there wasn't time to fix it. He thought about explaining what hap- pened, but he was worried it would sound like an excuse and make him less likely to win. He could put a battery in the car and act like nothing was wrong. But when he thought about it, he felt uncomfortable. He was proud of being honest, and the idea of cheating, even a little bit, made him feel sick. 　　As he walked to school, his steps were slow and heavy. He thought about all the late-night hours he spent working at his work bench, how frustrated he was when the circuits didn't work, and how happy he was when the car finally moved using solar power. His dreams of winning the competition and being recog- nized for his hard work seemed to be going away. But then he remembered the talks at the dinner table a 第1讲　描述运动的基本概念 long time ago, when his parents told him how important it was to be honest, responsible, and keep trying. Their words kept playing in his mind. By the time he got to the school gates, a determined look was on his face. He knew exactly what he had to do. 注意:续写词数应为 150个左右。 Alex stood in front of the class and judges,feeling nervous. ______________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ Later that day,Alex received an email from the science fair organization. __________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ 第1讲　描述运动的基本概念 写作指导 情节线 情感线 故事要素 时间 a cool fall morning 比赛即将到来 (兴奋、满怀期待)  ↓ 太阳能电池板坏了 (震惊、沮丧) 地点 home, school 人物 Alex, Axel 第1讲　描述运动的基本概念 写作指导 情节线 情感线 情节 开端 热爱科学的高中生Alex准备带着他自己研究数月的太阳能汽车模型去参加科学项目的最终展示,希望借此在地区科学 展中获胜。出发前,弟弟Axel因好奇弄坏了汽车的太阳能电池板。  ↓ 纠结该怎么做?

He took a deep breath and began his presentation. “Today, I'd like to talk about my project on a solar-powered car. However, before coming here, an acci- dent happened. My little brother broke a part of the solar panel. I was so shocked and disappointed at first. But then I realized that honesty is more important than winning. So, what you see now is a damaged model. But the knowledge and effort behind it are real.” He then went on to explain the theory and his process of building the car. The audience listened attentively, some nodding in understanding. Later that day,Alex received an email from the science fair organization. His heart raced as he opened it. To his surprise, he had won an honorable mention. The email praised his honesty and his in-depth understand- ing of the project. It said that although his model was damaged, his integrity and the quality of his work im- pressed the judges. Alex felt a rush of joy and relief. He knew that his decision to be honest was the right 第1讲　描述运动的基本概念 one. This experience not only taught him the value of honesty but also made him more determined to pursue his love for science. 第1讲　描述运动的基本概念 $
