(明天/下周的这个时间...) at 9 o'clock tonight / tomorrow... (今晚/明天9点...) this time next month / year... (下个月/明年的这个时候...) in an hour / two days... (一小时后/两天后...) when + 时间从句 (当...的时候) 例句: Don't call me at 8 PM. I'll be having dinner with my family. (别在晚上8点给我打电话。我那时正在和家人吃晚饭。) At this time tomorrow, I 'll be flying to Paris. (明天这个时候，我正在飞往巴黎的途中。) What will you be doing this time next Friday? (下周五这个时候你会在做什么？) The meeting starts at 10. So, at 10:30, we 'll be discussing the budget. (会议10点开始。所以，在10点半，我们将会在讨论预算。) 2. 表示在将来某个时间段内持续进行的动作： 描述一个动作在未来一段时间内（不仅仅是某个点）会持续发生。 关键标志： 常与表示将来时间段的状语连用，如：all morning/afternoon/evening/night/weekend, from ... to ..., during ... 等。 例句: I 'll be studying all weekend for my exam. (我整个周末都会在复习准备考试。) He won't be working next week; he's on vacation. (他下周不会在工作；他在度假。) During the summer, they 'll be traveling around Europe. (在夏天期间，他们将会在欧洲各地旅行。) 3. 表示预料中或按常规、计划会发生的将来动作（较为委婉、客观）： 这种用法强调动作的发生是自然进程的一部分、是预料之中的结果或是事先安排好的，听起来比直接用 will do 更自然、更客观，有时也更委婉。常用于口语中预测或谈论未来的计划/安排。 例句: Good luck with your exam! I 'll be thinking of you. (祝你考试顺利！我会想着你的。) (自然的想法流露) The train will be arriving at platform 3 shortly. (列车即将到达3号站台。) (时刻表安排/常规事件) We 'll be staying at the Grand Hotel for two nights. (我们将在格兰德酒店住两晚。) (事先安排好的行程) Will you be using the car tonight? If not, can I borrow it? (你今晚会用车吗？如果不用，我能借吗？) (比 Will you use... 更委婉询问计划) 4. 礼貌地询问他人未来的计划（避免强加感）： 用将来进行时询问别人的计划，听起来比用一般将来时 (Will you...?) 更礼貌、更不唐突，因为它暗示这个动作是对方正常计划中的一部分，而不是你临时强加的要求。 例句: Will you be joining us for dinner tonight? (你今晚会来和我们一起吃晚饭吗？) (礼貌询问对方原本是否有此打算) Will you be needing any help with the report? (你写报告时会需要帮忙吗？) (比 Will you need...? 更委婉) 一、单句语法填空 1．As an enthusiast of running, Jack (run) in the park at six o’clock tomorrow morning. 【答案】will be running 【详解】考查时态。句意：作为一个跑步爱好者，杰克明天早上6点钟正在公园跑步。根据后文at six o’clock tomorrow morning可知为将来进行时，故填will be running。 2．In the not-too-distant future, we (live) in smart homes that will lock the door for us when we are away. 【答案】will be living 【详解】考查时态。句意：在不远的将来，我们将生活在智能家居中，当我们离开时，它会为我们锁门。此处在句中作谓语，句子描述将来某一时间将要发生的事，是对未来的预测，应用将来进行时，故填will be living。 3．At 6 o’ clock tomorrow afternoon, we (practise) basketball skills. 【答案】will be practising 【详解】考查动词时态。句意：明天下午6点，我们将练习篮球技巧。空处作谓语，根据At 6 o’ clock tomorrow afternoon可知，表示将来具体时间点正在发生的事情，用将来进行时will be doing。故填will be practising。 4．I’m not available at three o’clock this Saturday.

One such startup was Skipping Rocks Lab, which came up with 2 idea of the Ooho eatable water bottle. The product is actually a flexible globe in 3 water doesn’t leak and that can be swallowed once the liquid inside has been consumed. Each globe is made by dipping a chunk of ice into calcium chloride (氯化钙) to form a membrane and then into a brown algae (水藻) 4 (solve) to strengthen that membrane. After the water melts, the globe stays entire. Ooho bottles are economical to produce, requiring minimal money or energy,and they are environmentally friendly. Even if consumers choose not 5 (eat) the membrane,it biodegrades within a few weeks. However, Ooho bottles have failed to take off. At outdoor sporting 6 (event) and festivals, they have proven to be convenient for those who only need a quick, waste-free hydration (水合作用) boost. In spite 7 this, their delicate nature makes them unsuitable for everyday use. Furthermore, if they were to be sold in supermarkets, they 8 (will) likely need some kind of packaging due to concerns about cleaness and safety.

That’s way beyond the handful of days that these setups typically last for before they have to be adjusted — which shows the promise and potential of the tech, according to the University of California, San Francisco (UCSF) research team. Crucial to the brain-computer interface (BCI) system are the AI algorithms (算法) used to match specific brain signals to specific movements. The man is able to watch the robot arm movements in real time while imagining them, and achieve greater accuracy with the robotic actions, because if anything goes against his original intentions, he can rectify it in time. “This combination of learning between humans and AI is the next phase for these brain-computer interfaces,” says neurologist Karunesh Ganguly, from UCSF. “It’s what we need to achieve complicated, life-like functions.” Guiding the robotic arm through thoughts alone, the man could open a cupboard, take out a cup, and place it under a water fountain. The tech has great potential to support people with disability in a wide variety of actions. Among the discoveries made during the course of the research, the team found that the shape of the brain patterns related to movement stayed the same, but their location changed slightly over time — something that’s thought to happen as the brain learns and takes on new information. The AI was able to address this change thanks to the algorithms, which meant the system didn’t need frequent adjustment. What’s more, the researchers are confident that the speed and the accuracy of the setup can be improved over time. Notably, the system functioned entirely through willpower alone, with no machine assistance. The system has given voices to those who can no longer speak and helped a man with tetraplegia play games of chess. While there’s still a lot more work to do, as the technology keeps on improving, more complex actions will become possible. 1．What does the underlined word “rectify” in paragraph 2 mean? A．Correct. B．Ignore. C．Repeat. D．Simplify. 2．What can we know about the BCI system? A．It needs external devices to interpret brain signals. B．It requires users to verbally command the robotic arm. C．It is currently limited to basic movements like holding objects. D．It enables users to perform complex daily tasks independently. 3．How does the AI algorithm contribute to the BCI system’s effectiveness? A．By predicting errors in real-time robotic actions. B．By enhancing the speed of robotic arm movements. C．By adapting to slight changes in brain signal locations. D．By fixing the location of brain patterns related to movement. 4．What is the author’s attitude toward the BCI system’s future? A．Optimistic. B．Uncaring. C．Worried. D．Doubtful. 【答案】1．A 2．D 3．C 4．A 【导语】本文是一篇说明文。文章介绍了一种新型脑机接口（BCI）系统如何通过结合AI和机器人技术，帮助四肢瘫痪患者通过思想控制机械臂完成日常动作，并探讨了其技术原理、优势及未来潜力。 1．词句猜测题。根据第二段“The man is able to watch the robot arm movements in real time while imagining them, and achieve greater accuracy with the robotic actions, because if anything goes against his original intentions, he can rectify it in time.(该男子能够在想象的同时实时观察机器人手臂的运动，并通过机器人动作实现更高的准确性，因为如果有任何违背他初衷的事情，他可以及时rectify)”可知，如果机械臂的动作与他的初衷有任何违背，他就能及时纠正，这样才能通过机器人动作实现更高的准确性，故画线词意思是“纠正”。A选项“Correct.(纠正)”符合题意。故选A。 2．细节理解题。根据文章第四段“Guiding the robotic arm through thoughts alone, the man could open a cupboard, take out a cup, and place it under a water fountain. The tech has great potential to support people with disability in a wide variety of actions.(仅通过思维控制机械臂，这名男子就能打开橱柜、取出杯子并将其放置在饮水机下方。这项技术在支持残疾人士进行各种动作方面具有巨大潜力。)”可知，这项技术有很大的潜力，可以帮助残疾人在各种行动中获得支持。由此可知，BCI系统能够让用户独立执行复杂的日常任务。故选D。 3．细节理解题。根据文章第五段“Among the discoveries made during the course of the research, the team found that the shape of the brain patterns related to movement stayed the same, but their location changed slightly over time — something that’s thought to happen as the brain learns and takes on new information. The AI was able to address this change thanks to the algorithms, which meant the system didn’t need frequent adjustment. (在研究过程中，研究团队发现，与运动相关的大脑信号模式的形状保持不变，但它们的位置会随着时间的推移而略有变化——这被认为是大脑在学习和接收新信息时发生的情况。人工智能之所以能够应对这种变化，要归功于算法，这意味着该系统无需频繁调整。)”可知，AI算法通过适应脑信号位置的轻微变化（而非预测错误、提升速度或固定位置）提升系统有效性。故选C。 4．推理判断题。根据文章最后一段“Notably, the system functioned entirely through willpower alone, with no machine assistance. The system has given voices to those who can no longer speak and helped a man with tetraplegia play games of chess. While there’s still a lot more work to do, as the technology keeps on improving, more complex actions will become possible.(值得注意的是，该系统完全依靠人的意志力运行，没有机器辅助。该系统为那些无法说话的人赋予了声音，并帮助一位四肢瘫痪的男子下象棋。虽然还有大量的工作要做，但随着技术的不断进步，更复杂的动作也将成为可能。)”可知，针对该系统虽然有大量的工作要做，但随着技术的不断进步，更复杂的动作也将成为可能，并且可以为人类提供帮助，由此作者对BCI系统的未来持乐观态度。故选A。 （24-25高二下·湖南邵阳·期末）Backpackers are all too familiar with the uncomfortable burden of a heavy bag, but scientists are investigating methods to lighten the load. A recent study by a Chinese research team introduced a backpack design that significantly reduces the amount of energy required by the user to carry it. Typically, as a person takes a step, the load inside their backpack often shifts up and down, pushing against the inside of the backpack with extra force, which can make the bag feel heavier than it actually is. “A backpack capable of minimizing these forces addresses a real pain point for many people who carry heavy loads during commuting, hiking, or running,” says Yanhe Zhu, a researcher at the Harbin Institute of Technology. “A product that can reduce this burden while enhancing comfort and flexibility would likely be very appealing.” Unlike existing suspension backpacks that use energy-consuming motors, Zhu and his team developed one that requires almost no external power. The backpack uses springs and sticks to balance the load, while a motor-controlled dampener (阻尼器) prevents the load from hitting the bag’s walls. When the load moves close to the walls, the dampener adjusts to cancel out the movement, and the energy it uses is sent back to the motor. This means only a small amount of power is needed to control the system, making it much more energy-efficient than other designs that need extra power for the motor. In experiments, volunteers wore both a regular backpack and the new design while walking on a walking test platform. The results demonstrated that the new design reduced energy use by over 11 % compared to a conventional backpack. Zhu believes this technology holds significant commercial potential, and is interested in exploring ways to introduce it to market. “Our following task will involve integrating intelligent algorithms (算法) to enable the suspension backpack to adjust to a broader range of movement patterns, such as jumping,” says Zhu. 1．What is the main issue with traditional backpacks mentioned in the text? A．They are too heavy when empty for most users. B．The load inside moves vertically, creating extra force. C．They lack modern aesthetic stylish designs for commuters. D．They require periodic motor frequent replacement of motors. 2．What does the underlined phrase “minimizing these forces” in paragraph 2 refer to? A．Reducing the overall weight of the backpack. B．Preventing the backpack from wearing out quickly. C．Decreasing the extra forces caused by load movement. D．Using lighter materials to make the backpack. 3．How does the new backpack achieve energy efficiency? A．By recycling energy through springs and a dampener system. B．By using high-power motors to stabilize the load. C．By eliminating all mechanical components. D．By relying solely on external electrical power sources. 4．What is the research team’s next plan for the backpack? A．To reduce the backpack’s weight further. B．To increase the motor’s power for faster adjustments. C．To design more fashionable styles for consumers. D．To blend smart algorithms for diverse movements. 【答案】1．B 2．C 3．A 4．D 【导语】本文是一篇说明文。文章主要讲述了科学家致力于减轻背包客沉重背包负担的研究。 1．细节理解题。根据第二段“Typically, as a person takes a step, the load inside their backpack often shifts up and down, pushing against the inside of the backpack with extra force, which can make the bag feel heavier than it actually is. (通常，当一个人迈出一步时，背包里的负荷经常上下移动，以额外的力量推着背包的内部，这可能会使背包感觉比实际要重)”可知，传统背包的主要问题是里面的负载会垂直移动，产生额外的力，这使得背包感觉比实际更重。故选B。 2．词句猜测题。根据上文提到传统背包负载移动会产生额外力，结合“addresses a real pain point for many people who carry heavy loads during commuting, hiking, or running (解决了许多在通勤、徒步旅行或跑步时携带重物的人的一个真正的痛点 )” 可推知，“minimizing these forces”指的是减少由负载移动引起的额外力。故选C。 3．细节理解题。根据第三段“The backpack uses springs and sticks to balance the load, while a motor-controlled dampener (阻尼器) prevents the load from hitting the bag’s walls. When the load moves close to the walls, the dampener adjusts to cancel out the movement, and the energy it uses is sent back to the motor. This means only a small amount of power is needed to control the system, making it much more energy-efficient than other designs that need extra power for the motor. (背包使用弹簧和杆件来平衡负载，而电机控制的阻尼器可以防止负载撞击包壁。当负载靠近墙壁移动时，阻尼器调整以抵消运动，并且它使用的能量被发送回电机。这意味着只需要少量的电力来控制系统，这使得它比其他需要额外电力的设计更节能)”可知，新背包通过弹簧和阻尼器系统回收能量来实现能源效率。故选A。 4．细节理解题。根据最后一段““Our following task will involve integrating intelligent algorithms (算法) to enable the suspension backpack to adjust to a broader range of movement patterns, such as jumping,” says Zhu. (朱说：“我们接下来的任务将涉及集成智能算法，使悬架背包能够适应更广泛的运动模式，比如跳跃。”)”可知，研究团队下一步计划是融合智能算法以适应多样化的运动。故选D。 1 / 12 学科网（北京）股份有限公司 $$ Unit 2 Looking into the Future 核心语法精练（将来进行时） 目录 1 B 考点夯基·专项突破 3 一、单句语法填空 3 二、完成句子 4 三、选词填空 5 C 综合攻坚·能力跃升 6 题型一 语法填空（模考真题） 6 题型二 阅读理解（模考真题） 7 将来进行时 (Future Continuous Tense 或 Future Progressive Tense) 是英语中用来描述在未来某个特定时间点或时间段正在进行或预计会持续进行的动作的时态。它强调动作的持续性和进行性。 核心结构： will + be + 动词的现在分词 (V-ing) 肯定句: 主语 + will + be + 动词-ing + ... 否定句: 主语 + will not (won't) + be + 动词-ing + ... 疑问句: Will + 主语 + be + 动词-ing + ...? 主要用法与含义： 1. 表示在未来特定时间点正在进行的动作： 这是将来进行时最核心的用法。它让你能够“展望”未来，想象在某个精确的时刻或短暂的时间段里，某个动作正在进行中。 关键标志： 常与表示具体将来时间点的状语连用，如： at this time tomorrow / next week...

Not only are these bottles 1 (significant) harmful to the environment, but they also pose threats to our health. Therefore, startup companies have been trying to find sustainable alternatives to this plastic membrane (薄膜). One such startup was Skipping Rocks Lab, which came up with 2 idea of the Ooho eatable water bottle. The product is actually a flexible globe in 3 water doesn’t leak and that can be swallowed once the liquid inside has been consumed. Each globe is made by dipping a chunk of ice into calcium chloride (氯化钙) to form a membrane and then into a brown algae (水藻) 4 (solve) to strengthen that membrane. After the water melts, the globe stays entire. Ooho bottles are economical to produce, requiring minimal money or energy,and they are environmentally friendly. Even if consumers choose not 5 (eat) the membrane,it biodegrades within a few weeks. However, Ooho bottles have failed to take off. At outdoor sporting 6 (event) and festivals, they have proven to be convenient for those who only need a quick, waste-free hydration (水合作用) boost. In spite 7 this, their delicate nature makes them unsuitable for everyday use. Furthermore, if they were to be sold in supermarkets, they 8 (will) likely need some kind of packaging due to concerns about cleaness and safety.
