选择性必修第1册 Unit 4 Body Language(Word练习)-【创新教程】2025年高考英语艺考生文化课总复习（人教版2019）

Ⅰ.阅读理解 [话题：通过步态，识别个人] One Chinese startup (科技创业公司) apparently developed technology that allows it to identify individuals by their walk, even if their face is covered or they have their back to the camera. Known as “gait recognition” (步态识别技术), the technology invented by artificial intelligence startup Watrix analyses thousands of metrics (指标) about a person's walk, from their body shape and the angle of arm movement to their posture and whether they have a toe­in or toe­out gait.All these individual features go into a database that the software then goes through when attempting to identify people.According to an official statement from Watrix, the accuracy rate of gait technology at the laboratory level exceeds (超过) 96 percent. Facial recognition technology has come a long way in recent years, but it still has a fundamental weakness — it needs to “see” people's faces in order to identify them, so if someone's face is covered or if their back is to the camera, it's basically useless.Gait recognition, on the other hand, is much more reliable.It works from virtually any angle, and because it analyses so many metrics, it can identify subjects even if they attempt to cover their legs.Disguises (伪装物) or fake limps are not very effective in fooling the technology either. “Covering your legs would reduce the recognition score but we analyse all of a person's body，” Huang Yongzhen, co­founder and chief executive of Watrix, said in an interview.“With facial recognition people need to look into a camera — cooperation is not needed for them to be recognized by our technology.” Watrix revealed the first version of their gait recognition technology in October, 2018 and has since been in talks with security companies from Singapore, India, Russia, the Netherlands, and Czech Republic for contracts.The technology has also been tested by public security officials for thousands of hours and used to solve dozens of police cases.Authorities in Shanghai and Beijing are already using gait recognition to detect wanted criminals and identify jaywalkers (乱穿马路者)． The current version of gait recognition software isn't yet capable of detecting people in real time, but the Chinese startup claims that it's able to analyse an hour's worth of video footage in just 10 minutes, with over 94% accuracy. 1．How could Watrix guarantee the accuracy of “gait recognition”？ A．By checking the angle of people's arm movement. B．By combining facial recognition with people's walk. C．By establishing a database of numerous individuals' metrics. D．By analysing thousands of features of people's legs and toes. 2．What advantage does gait technology have over facial recognition? A．Unlimited angles. B．Free gestures. C．No need to cover. D．Active cooperation. 3．What can we learn from the fifth paragraph? A．Watrix has found several cooperative partners for its first version. B．Gait recognition has been widely used in the field of public security. C．Watrix is trying to extend the use of the technology in Chinese big cities. D．Gait technology has been proved beneficial in identifying wanted criminals. 4．Which of the following can best describe the future of the technology? A．Challenging.　　　 B．Promising. C．Profitable. D．Unknown. [语篇解读]　本文是一篇说明文。主要介绍了一家中国初创公司开发出了通过步态来识别个人的技术。 1．C　[细节理解题。根据第二段中的“Known as ‘gait recognition’(步态识别技术), the technology invented by artificial intelligence startup Watrix analyses thousands of metrics (指标) about a person's walk, from their body shape and the angle of arm movement to their posture and whether they have a toe­in or toe­out gait.All these individual features go into a database that the software then goes through when attempting to identify people.(这项被称为‘步态识别’的技术是由人工智能初创公司Watrix发明的，它分析了关于一个人走路的数千个指标，从他们的体型、手臂运动的角度到他们的姿势，以及他们是脚趾向内还是脚趾向外的步态。所有这些个人特征都被输入一个数据库，然后软件在尝试识别人员时会通过该数据库进行检索。)”可知，Watrix通过建立一个包含众多个人指标的数据库来保证“步态识别”的准确性。] 2．A　[细节理解题。根据第三段中的“Gait recognition, on the other hand, is much more reliable.It works from virtually any angle, and because it analyses so many metrics, it can identify subjects even if they attempt to cover their legs.(另一方面，步态识别从几乎任何角度都是更可靠地工作，因为它分析了如此多的指标，即使试图遮住他们的腿，它也能识别出受试者。)”可知，与面部识别相比，步态技术的优点是几乎任何角度都可以更可靠地工作，即无识别角度限制。] 3．D　[推理判断题。根据第五段中的“The technology has also been tested by public security officials for thousands of hours and used to solve dozens of police cases.Authorities in Shanghai and Beijing are already using gait recognition to detect wanted criminals and identify jaywalkers.(该技术还经过公安人员数千小时的测试，并被用于侦破数十起警方案件。上海和北京的有关部门已经在使用识别技术来侦查通缉犯和识别乱穿马路的行人。)”可推知，步态识别技术已被证明有助于识别通缉犯。] 4．B　[推理判断题。根据倒数第二段中的“Watrix revealed the first version of their gait recognition technology in October, 2018 and has since been in talks with security companies from Singapore, India, Russia, the Netherlands, and Czech Republic for contracts.(Watrix在去年10月公布了他们的步态识别技术的第一个版本，此后一直在与来自新加坡、印度、俄罗斯、荷兰和捷克共和国的安全公司进行合同谈判。)”和最后一段“The current version of gait recognition software isn't yet capable of detecting people in real time, but the Chinese startup claims that it's able to analyze an hour's worth of video footage in just 10 minutes, with over 94% accuracy.(目前版本的步态识别软件还不能实时检测人。这家中国初创公司声称，它能够在短短10分钟内分析一小时的视频片段，准确率超过94%。)”可推知，Watrix与来自新加坡、印度、俄罗斯、荷兰和捷克共和国的安全公司进行合同谈判，同时当前版本能够在短短10分钟内分析一小时的视频片段，准确率超过94%，因此这项技术的未来是有前途的。] Ⅱ.七选五 [话题：身体语言，注意应用] When it comes to making a good impression, you can say all the right things.But it won't be helpful until they are accompanied with the right body language. 　　__1__　.Weak handshakes can make you seem anything but confident.Your handshake should be firm but not too tight, because you won't impress anyone by giving them a painful hand.
