51、kOne thing I think we all agree on is that【主题阅读】.阅读理解A(2020北京高二检测)Elon Musk,perhaps the worlds most famous businessman,has a habit of making statements that stretch the bounds of believability.On July 16th,2019,he introduced a new type of brain-machine interface(BMI),starting from the design of a“ne

52、ural lace(神经织网)”,a net of thin electrodes(电极)that capture the information from the brain.However,the electrodes must be flexible,so that they do not damage brain tissue and will lastfor a long time.And to make the implantation(植入)of so many electrodes safe,painless and effective,the process has to b

53、e automated.Mr Musks team does indeed seem to have made progress towards these goals.Its presentation included videos of a robot that is best described as a sewing machine.This robot grabs“threads”,and shoots them deep into the brain through a hole.The firm has also designed a chip that can handle s

54、ignals from as many as 3,072 electrodes.With all these technological breakthroughs,the firm now hopes to help people overcome such illnesses as blindness and paralysis.They designed a small device that would sit behind someones ear,picking up signals from the implanted chip and passing them on as ap

55、propriate.In a few years,using a brain implant to control your devices may be as prevalent as wearing wirelessearphones today.Finally,Musk predicts neural lace will allow humans to be combined with AI systems,thus enabling the species to survive.Though,as this announcement shows,Mr Musk does have a

56、habit of presenting himself as the hero of the human race,the idea that some machines at least will come under the direct control of human brains seems possible to be carried out.The biggest barrier to this happening will probably not be writing the software needed to interpret brainwaves,but rather

57、 persuading people that the necessary surgery,whether by sewing machine or otherwise,is actually a good idea.【文章大意】这是一篇说明文。文章主要介绍了Elon Musk提出的新型脑机交互的想法,并从现今研究成果和未来应用前景进行了详细说明。1.We can learn from the first two paragraphs that _.A.electrodes should be flexible to extend lifeB.Elon Musk constantly come

58、s up with unexpected ideasC.a neural lace is used to store information from the brainD.electrodes are implanted by top surgeons for safety reasons【解析】选B。推理判断题。根据第一段中“Elon Musk.has a habit of making statements that stretch the bounds of believability.和第二段中“On July 16th,2019,he introduced a new type o

59、f brain-machine interface(BMI)”可知Elon Musk经常能提出前所未闻的想法,B项符合题意。2.What does the underlined word“prevalent”in Paragraph 4 probably mean?A.Useful.B.Common.C.Professional.D.Appropriate.【解析】选B。词义猜测题。根据第四段中“They designed a small device that would sit behind someones ear,picking up signals from the implante

60、d chip and passing them on as appropriate.”可知,现在设计的小设备安装在人的耳后,从植入芯片中收集信息,然后以合适的方式传递下去。表明现在的应用较为复杂。画线词所在句的表述为几年后,与现在形成对比关系,表明这项技术会变得更为普遍和简易。通过翻译选项可知,B项common“普遍的”切合题意。故选B。3.What is the hardest part of carrying out BMI?A.Convincing people to accept the surgery.B.Developing devices to perform the surge

61、ry.C.Writing the software to interpret brainwaves.D.Informing people of the success of the surgery.【解析】选A。细节理解题。根据最后一段中“The biggest barrier to this happening will probably not be writing the software needed to interpret brainwaves,but rather persuading people that the necessary surgery.”可知,最大的阻碍可能不是

62、写脑电波所需的软件,而是说服人们做必要的外科手术。意在表明BMI最艰难的部分是说服人们接受必要的外科手术。故选A。4.What is the best title of this passage?A.The Neural Lace,A New Type of BMIB.Elon Musk,the Hero of Human BeingsC.Artificial Intelligence,the Way to SurviveD.A Brain Implant,A Step to Control Machines【解析】选A。主旨大意题。根据第二段中“On July 16th,2019,he in

63、troduced a new type of brain-machine interface(BMI).”可知2019年7月16日,他提出了一个关于新型脑机交互的想法。接下来全文围绕新型脑机交互(BMI)进行展开说明,因此可知A项“神经织网,一种新型的脑机交互”切题。故选A。【方法技巧】猜测词义题旨在考查学生根据上下文推测生词、短语或句子意思的能力,突出考查对语境的分析和把握能力。是阅读理解的常考题型,题干中通常含有mean,refer to或者be replaced by等。例如第2小题中的“In a few years,using a brain implant to control yo

64、ur devices may be as prevalent as wearing wireless earphones today.”根据同位或解释关系,当作者不能十分确定读者能够理解他的意思时,会用另外一种方式来进一步详细解释或用类比关系衬托自己的观点表述。句中as起到了连接前后句语境的作用,通过后句的类比关系暗示画线词的含义,考生要将前后两句都读完才能理清语境间内在联系,进而准确地推测出画线词的含义。BThe oddness of life in space never quite goes away.Here are some examples.First consider somet

68、 with what astronauts call a carbon-dioxide headache.Leroy Chiao,54,an American retired astronaut after four flights,describes what happens even before you float out of your seat.“Your inner ear thinksyoure falling.Meanwhile your eyes are telling you youre standing straight.That can be annoyingthats

69、 why some people feel sick.“Within a couple of daystruly terrible days for some astronauts brains learn to ignore the panicky signals from the inner ear,and space sickness disappears.Space travel can be so delightful but at the same time invisibly dangerous.For instance,astronauts lose bone mass.Tha

70、ts why exercise is considered so vital that National Aeronautics and Space Administration(NASA)puts it right on the workday schedule.The focus on fitness is as much about science and the future as it is about keeping any individual astronaut healthy.NASA is worried about two things:recovery time onc

71、e astronauts return home,and,more importantly,how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.【文章大意】这是一篇说明文。本文通过举例说明了太空生活的奇妙:在太空睡觉时,对宇航员来说主要的挑战在于合适的睡眠姿势;宇航员在一个地方运动久了会出现碳毒性头痛;宇航员的大脑接收到矛盾的信息时会感到恶心。最后告诉我们美国国家宇航局对宇航员主要的担心是宇航员回家后的修

74、ile pedaling【解析】选C。细节理解题。根据第三段中“But station residents have to be careful about staying in one place too long.You can end up with what astronauts call a carbon-dioxide headache.”可知宇航员在一个地方待久了会出现碳毒性头痛。故选C。7.Some astronauts feel sick on the station during the first few days because_.A.their senses stop

75、 workingB.they have to stand up straightC.they float out of their seats unexpectedlyD.their brains receive contradictory messages【解析】选D。细节理解题。根据第四段中“Your inner ear thinks youre failing.Meanwhile your eyes are telling you youre standing straight.That can be annoyingthats why some people feel sick.”可知

76、宇航员在大脑接收到矛盾的信息时会感到恶心。故选D。8.One of NASAs major concerns about astronauts is_.A.how much exercise they do on the stationB.how they can remain healthy for long in spaceC.whether they can recover after returning homeD.whether they are able to go back to the station【解析】选B。细节理解题。根据最后一段倒数第一、二句“The focus on

77、 fitness is as much about science and the future as it is about keeping any individual astronaut healthy.NASA is worried about two things:.and,more importantly,how to maintain strength and fitness.”可知美国国家宇航局对宇航员主要的担心之一是如何在太空长久地保持健康。故选B。.阅读填句(2020慈溪高二检测)After a long day at work,coming home is a breat
