Ⅵ.新素材 人脸识别系统的应用 (2025·安徽合肥庐阳中学期中)阅读理解
人脸识别系统的应用已经越来越普及了,但其潜在的安全问题也应引起关注。
精题详解
①Facial recognition (人脸识别) is used everywhere. Many people use it to unlock (解锁) their phones, open doors or pay quickly. Now, people can even make this happen with masks (口罩) on their faces.
②For example, Engineering & Technology (E & T) magazine said that Hanwang, a company in Beijing, has made a system (系统). For people wearing masks, it can tell who they are 95 percent of the time.
③How? It's all about your eyes.
④Marios Savvides from Carnegie Mellon University, USA, studies facial recognition. As we get older, our faces change shape, he explained. But the part around our eyes doesn't. It stays the same—even if we become fatter. As long as there are enough data (数据) from the parts around our eyes, the cameras can know us.
⑤Tech5 is another facial recognition company. The Swiss company's product (产品) studies the shape of your face. It also studies your iris (虹膜), which is the coloured part of your eyes. Tech5 hopes to leave out all of the face below the nose.
⑥This kind of tool has more uses than just unlocking your phone. Huang Lei from Hanwang thinks that it can help find bad people even when they wear masks. Chinese police use it in places like subway stations and airports. Similar technology is used by the United States Air Force. Huang pointed out one big problem: It doesn't work when people wear both a mask and sunglasses. “In this situation, all of the key facial information is lost,” Huang said to E & T.

答案： 【解析】：
这是一道英语阅读理解题，主要考查学生从文章中获取信息、理解文章细节以及进行推理判断的能力。题目围绕人脸识别系统展开，包括其应用、解决的新问题、识别原理、不同公司的识别技术以及存在的不足等方面。
1. 第一题是细节理解题，需要从第一段中找出科学家解决的最新问题。
2. 第二题也是细节理解题，要根据Marios Savvides所说的内容来判断选项。
3. 第三题同样是细节理解题，从文中找出Tech5在面部识别技术中使用的部分。
4. 第四题是推理判断题，从第六段内容推断出相关信息。
5. 第五题是推断文章出处题，根据文章主题判断可能出自杂志的哪个部分。
【答案】：
1. D。根据第一段“Now, people can even make this happen with masks (口罩) on their faces.”可知科学家解决的最新问题是即使戴着口罩也能识别面部，所以选D。
2. B。由第四段“But the part around our eyes doesn't. It stays the same—even if we become fatter.”可知眼睛周围的部分形状不会随时间改变，B选项正确；A选项“Cameras can always tell who people are by the shape of their face.”与原文不符；C选项“Facial recognition technology works better on young people.”文中未提及；D选项“Getting fatter may change the shape of our eyes.”与原文“the part around our eyes doesn't change”相悖。
3. C。从第五段“The Swiss company's product (产品) studies the shape of your face. It also studies your iris (虹膜), which is the coloured part of your eyes.”可知Tech5使用虹膜进行面部识别，选C。
4. B。第六段提到“Huang pointed out one big problem: It doesn't work when people wear both a mask and sunglasses. ‘In this situation, all of the key facial information is lost,’”可知新技术存在不足，B选项正确；A选项“Ways for bad people to hide.”不是该段重点；C选项“Different types of facial recognition software.”不是该段主要内容；D选项“The way China and the USA are working together.”文中未体现。
5. C。文章主要围绕人脸识别系统这一科技话题展开，所以可能出自杂志的“Science and technology”部分，选C。
