    一、阅读理解
    When we long live together, we quickly learn to foresee the near-term behaviors of our co-workers or family members. Our ability to predict the actions of others makes it easier to successfully live and work together. In contrast, even the most intelligent and advanced robots have remained inept at this sort of communication. This may be about to change.
    The study, conducted by Mechanical Engineering Professor Hod Lipson, is part of a broader effort to provide robots with the ability to understand and predict what others want. The researchers first built a subject robot and placed it in a playpen. They programmed the robot to seek and move towards any green circle it could see. But there was a hidden difficulty: Sometimes the robot could see a green circle in its camera and move directly towards it. But other times, the green circle would be blocked by a tall red cardboard box, in which case the robot would move towards a different green circle, or not at all.
    After “researching” its partner on screen long, the new robot was eventually able to get its partner’s goal and path 98 out of 100 times, across varying situations. When starting the experiment, the researchers expected the robot might learn to make predictions about the subject robot’s near-term actions. What the researchers didn’t expect, however, was how accurately it could foresee the moves with only a few seconds of video.
    “Our initial results are very exciting, showing how robots can see the world from another robot’s view,” says Lipson. “The understanding ability of the new robot is perhaps a primitive form of sensing others’ feelings, which we all can do.”
    Meanwhile, he acknowledges there’re many moral questions. The technology will make robot more adaptable and useful and no longer passive instruction-following machines, but when robots ca predict how humans think, they may also learn to control or influence those thoughts.
    1.What does “inept” underlined in the first paragraph mean’?
    A.Careful. B.Smart. C.Active. D.Poor.
    2.What is the experiment designed to find?
    A.How a robot moves toward the targeted object.
    B.Whether a robot can predict other robots’ goals.
    C.Whether robots can work together like humans.
    D.How accurately a robot foresees its partner’s moves.
    3.How does the robot gain the understanding ability?
    A.By communication. B.By following its camera.
    C.By visual observation. D.By experiencing various tests.
    4.What does Lipson think of the new robot?
    A.It bears human characteristics. B.It has some kind of moral values.
    C.It might replace human beings. D.It is an instruction-following machine.

    Are you interested in robot-science? What do you think robots are capable of? Let’s have a review of world-leading technology gathered at the World Robot Conference (WRC) 2022.
    Technology in agriculture
    A fruit-picking robot attracted visitors’ attention. With the help of various sensors and an AI system, the robot can collect fruit according to its ripeness, quality and size. The robot first locates the fruit and then uses sensors to decide whether it is ripe, with a robotic arm picking the fruit gently. The fruit is then categorized, ending up in a basket according to its size. It is said that more robotic technology will be used in agriculture in the future, including robots for daily inspection and weeding.
    Robots fighting Covid-19
    Medical staff conducting nucleic acid tests often find their work toilsome, especially under the summer heat. A nucleic acid test robot developed by Tsinghua University and a Chinese biotech company was presented at the WRC.It looks like a vending machine, but the robot can collect throat swabs (拭子), process samples, as well as produce and upload the results within 45 minutes. The whole process will not require the involvement of humans or laboratories.
    Inventions of the youth
    Those visiting the exhibit also witnessed the intelligence of a new generation. Wang Zirun, a junior student at the school, designed a three-dimensional parking facility model. Since there are usually too few parking spaces in older residential areas, Wang’s work aims to fit more cars into current parking spots. The facility works like a sky wheel with six parking spots. When cars need to be picked up, the facility rotates steadily, placing the car on the ground.
    5.Why is the parking facility designed like a sky wheel?
    A.To make the most of limited space.
    B.To prevent cars from being stolen.
    C.To increase ground parking spaces.
    D.To save building materials.
    6.What can we infer from the text?
    A.Human can be replaced by the robot in the future.
    B.The WRC is intended to inspire the intelligence of a young generation.
    C.All the inventions mentioned have been put into practical use.
    D.Both the fruit-picking robot and the nucleic acid test robot can save manpower.
    7.Where is the text probably taken from?
    A.A travel brochure. B.A science magazine.
    C.A technology textbook. D.A product advertisement.

    Heat is the biggest end use for energy all over the world. It’s also critically important for survival in a country like Finland where the winter is long, cold and dark. And the recent move by Russia to cut off supplies of gas and electricity in response to Finland joining NATO has caused concern.
    There is good news, however, that the world’s fully first working sand battery has been installed in Finland. It is a device which can store sustainably produced heat for months at a time and can be used to keep homes warm in winter. That’s why the new technology was developed by researchers there. Researchers believe it can solve the country’s year-round crisis in power supply, which is a significant issue for green energy.
    The sand battery was installed in the Vatajankoski power plant that runs the heating system for the houses in the area. It works by heating the sand, circulating the heat generated in the sand using a heat exchanger. Researchers used low-grade sand to charge the devices with heat from cheap electricity coming from either solar or wind energy. The sand battery can store energy and heat up to 500 degrees Celsius. which can be used to warm homes during winter when electricity is more expensive.
    It is a cost-effective method because when the battery releases the hot air, it warms the water for the district heating system that is pumped around homes, offices, and the local swimming pool. Sand is an ideal material because it is cheap and readily available everywhere. While other inexpensive items like water can store heat, sand can be heated to much higher temperatures. The sand used is of the lowest quality so it cannot be used in construction thus making it a sustainable choice. Besides, sand-based batteries last longer than other batteries. According to a study, researchers obtained silicon using sand to create a battery that lasts three times longer than lithium-ion(锂离子) batteries.
    “This innovation is a part of the smart and green energy transition. Heat storage systems can significantly help to increase intermittent (间歇性的) renewables in the electrical network,” said Markku Ylönen, cofounder of Polar Night Energy. “At the same time, we can make full use of the heat waste to keep the city warm.”
    8.Why did researchers install sand battery in Finland?
    A.Because Finland is in desperate need of it owing to the climate.
    B.Because people there can use it to keep warm in summer.
    C.Because Russia cut off supplies of gas and electricity there.
    D.Because sand in Finland can generate a great deal of solar power.
    9.How does the sand battery work?
    A.It generates electricity with seawater. B.It stores heat from green energy.
    C.It charges electronic devices. D.The hot air is circulating inside a plant.
    10.Sand is used in this new technology mainly because ________.
    A.other material can’t store heat B.it is thrown everywhere
    C.it is a kind of unsustainable resource D.it is inexpensive
    11.What’s Markku Ylönen’s attitude towards the battery?
    A.Indifferent. B.Negative. C.Positive. D.Neutral.


    二、七选五
    Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and headaches to house fires. ___12___
    The theory is that the bees navigation (导航) systems are damaged by the radiation that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home. ___13___
    The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them. ____14____ Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been ruined by this,” he explained, “twenty-nine of my forty hives are now empty.”
    ___15___ However, the fact that bees are disappearing in very large numbers is real. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! ____16____ If the mobile phone theory is correct, we need to do something about it immediately—before it’s too late.
    A.Bees are losing their way.
    B.Nobody has proved the theory is true.
    C.More evidence is provided to support the theory.
    D.It is believed they are dying far from their hives.
    E.Without bees, the crops can’t continue to grow.
    F.The situation needs to be evaluated by the world’s best scientists.
    G.One theory even blames mobile phones for the disappearance of bees.


    三、完形填空
    Do you remember how you felt the first time you rode bike? What about your first heartbreak? ____17____ moments and the emotions they arouse can resonate in our minds for decades, powerfully shaping who we are as individuals. But for those who experience severe trauma(创伤), such painful memories can leave people with life-changing mental conditions. So, what if traumatic memories did not have to cause so much ___18___ ? For now, the work is happening in mice.
    Neuroscientists usually define a singular memory as an engram---a physical change in brain tissue ____19____ a particular recollection. While at MIT in 2013, Steve Ramirez of Boston University and his research partner Xu Liu had a breakthrough: They were able to target the cells that ___20___ one engram in a mouse's brain and then implant a false memory. In their work, mice __21__ in fear to a particular stimulus even when they had not been conditioned in advance.
    In their current work, Ramirez and his colleagues are investigating whether ___22___ memories can be “overwritten” by positive ones. In their experiments, positive memories are created by putting male mice in cages with female ones for an hour, and negative memories are created by putting the mice in cages that deliver brief foot shocks. After a surgical operation on the mice, the researchers find that ___23___ positive memories while mouse is in a cage makes it less fearful. They think that this memory “retraining"may be helping to ___24___ some of the mouse's trauma. ___25___ , it is unclear whether those original fear memories are completely lost or just suppressed(抑制).
    __26__ Ramirez’s team stresses that their work in mice is preliminary(初步的), they see treatment potential for humans down the road. Those suffering from PTSD or depression could have their memories ___27___ , for instance, so that they don't have a strong ___28___ response to painful recollections.
    If it’s one day possible to alter human memory, who should be allowed to receive that treatment? And would the ___29___ system be at a disadvantage if key witnesses and victims cannot remember a crime? These are questions New York University bioethicist Arthur Caplan says are worth thinking about before the technology is ready for human clinical settings.
    As neuroscientists progress with their research, they say these ___30___ issues are being taken into account. Ramirez sees the idea of  ___31___ memories as neither good nor bad. Like water, it just depends on how you use it.
    17.A.Forgettable B.Memorable C.Sustainable D.Believable

    23.考查动词词义辨析。句意:在对老鼠进行外科手术之后科学家们发现,当老鼠在笼子里的时候激活那些积极的记忆会让它不再那么恐惧。A.deleting 删除;B.decreasing 减少;C.activating 激活; D.pausing暂停。根据“positive memories are created by putting male mice in cages with female ones for an hour”,(科学家们对老鼠输入了积极的记忆),所以推测本句指“激活”这些积极记忆。故选C。
    24.考查动词词义辨析。句意:他们认为这种记忆的“重新训练”有助于去除掉老鼠的一些创伤。A.recreate重新创造; B.eliminate消除; C.liberate 解放;D.memorize记住。根据下文,“it is unclear whether those original fear memories are completely lost or just suppressed”(不知这些原始恐惧是否完全消失)可知,本句指这样做可以“消除”掉一些创伤。故选B。
    25.考查副词词义辨析。句意:然而,是否这些原始的恐惧记忆完全消除或抑制是不清楚的。A.Therefore 因此;B.Besides 另外;C.Indeed 实际上;D.However然而。根据上文“They think that this memory “retraining"may be helping to    8    some of the mouse's trauma. ”,这样做有助于消除恐惧记忆,下句又讲“能否完全消除还不清楚”,因此两句之间是转折关系。故选D。
    26.考查连词词义辨析。句意:尽管他们的团队强调他们在老鼠身上的成果只是初步的,但是他们也看到了在这条路上为人类治疗的潜力。A.Since因为; B.Unless 除非;C.Until 直到;D.While然而。根据从句中“preliminary(初步的)”一词,及主句中“潜力”一词,可推出主从句之间为转折关系。故选D。
    27.考查动词词义辨析。句意:例如,那些遭受抑郁的人们就可以让他们的记忆被转换,以致于他们对痛苦的经历没有一种强烈的反应。A.removed 移除;B.strengthened 加强;C.altered 转换;D.stimulated刺激。根据“Ramirez’s team stresses that their work in mice is preliminary(初步的), they see treatment potential for humans down the road”,“科学家们在对老鼠做实验的成效中,看到了人类治疗的潜能”,所以本句是这种“潜能”应用的例子,就是可以转换人的记忆。故选C。
    28.考查形容词词义辨析。句意:例如,那些遭受抑郁的人们就可以让他们的记忆被转换,以致于他们对痛苦的经历没有一种强烈的反应。A.emotional 情感的;B.physical 身体的C.controversial 传统的;D.mechanical机械的;本空修饰“response to painful recollection”’(人对痛苦回忆的反应),这种反应应该是“情感上的”。故选A。
    29.考查名词词义辨析。句意:如果关键的证人和受害者不能记得犯罪事件,那么执法系统会处于不利地位吗? A.immune 免疫的;B.justice 公正的,正义,执法制度;C.medical 医疗的;D.commerce商业。根据 “system be at a disadvantage if key witnesses and victims cannot remember a crime? ”意思,证人和受害者不记得犯罪事件后,那么“执法部门”就无法找到确切的犯罪证据。故选B。
    30.考查形容词词义辨析。句意:伴随着神经科学家们的研究进展,他们说这些道德上的问题也正在被考虑中。A.mental 精神的;B.ethical 道德上的,伦理的 ;C.criminal 罪犯的;D.equality平等性。根据“These are questions New York University bioethicist Arthur Caplan says are worth thinking about ”作者提出,如果这种技术应用在人身上后,会出现的各种问题可知,这些问题都属于“道德”方面的。故选B。
    31.考查动词词义辨析。句意:Ramirez认为这种控制记忆的想法既不是好的,也不是坏的,这取决于你怎样使用它。A.killing 杀害;B.multiplying 繁殖;C.controlling控制;D.justifying证明...合法,辩护。根据“memories can be “overwritten” by positive ones”可知,本文主要讲“改变人的记忆”的问题,所以这里应该是“控制记忆”。故选C。

    37.考查非谓语动词。句意:这次救援被认为是历史性的,因为这是第一次使用配备漂浮装置的无人机来营救这样的游泳者。分析句子结构和意思可知,动词equip和被修饰的名词drone是逻辑上的动宾关系,所以用过去分词形式,作后置定语。故填equipped。
    38.考查时态和语态。句意:警报响起时,救生员主管Jai Sheridan正在驾驶该设备。空处为状语从句的谓语动词,描述过去的动作,主语alarm和动词raise是被动关系,所以用一般过去时的被动语态,be动词用was。故填was raised。
    39.考查形容词。句意:他把这次经历描述为一次不真实的和难以置信的经历。分析句子结构可知,这里需要形容词作定语,结合下文unbelievable可知,空处意为“不真实的”。故填unreal。

    【详解】考查动词。句意:他劝我买这套房子,现在我很高兴那时他让我买。空处为句子谓语动词,根据句意和首字母提示可知,动词persuade“劝说”符合题意,persuade sb. to do sth.“劝说某人做某事”,结合语境和下文did判断此处陈述过去的事情,用一般过去时。故填persuaded。
    44.voluntarily##oluntarily
    【详解】考查副词。句意:我自愿参加了一个慈善项目,去广西农村培训那里的英语老师。take part in为动词短语,需要副词修饰,故填副词voluntarily,“自愿地”。故填voluntarily。

    【详解】考查形容词。句意:我相信人工智能将会有一个光明的前途。根据所给句子和汉语提示可推出是形容词artificial“人工的”,该词作为定语修饰名词intelligence,artificial intelligence“人工智能”,故填artificial。

    50.have been in touch with
    【详解】考查时态和主谓一致。句意:从那以后,我们一直通过电子邮件保持联系。根据时间状语since then可知,空处谓语动词需用现在完成时态,因为表示持续一段时间,所以空处需用持续性动词短语be in touch with…和……保持联系,主语是第一人称复数we,所以助动词需用have。故填have been in touch with。
    51.     constant     innovation
    【详解】考查形容词和名词。句意:经过几十年不断的改革和创新,深圳采取了许多对新兴企业有利的政策。根据汉语提示,第一空应用形容词constant,表示“不断的”,作定语修饰名词reform,第二空应用名词innovation,表示“创新”,与名词reform并列,作介词with的宾语。故填①constant,②innovation。

    【详解】考查动词时态和疑问词。结合句意,该句可用What引导的特殊疑问句表示。由“明天早上十点”和“会在干嘛”可知此处是指将来某个时间正在进行的动作,所以时态应为将来进行时,句型为:What will sb. be doing sth. (+其他)?此处为he,指“他”。句首字母要大写。故填What will he be doing。
