The company told a news agency that a team of 20 people built the system in about a month.The system is based on existing technologies developed over the past 10 years.The process involved adding a collection of about 6 million unmasked faces and a much smaller collection of masked faces, the company said. The company is now selling two main kinds of products that use the new technology.One performs “single channel” recognition, which is designed to be used at the entrances to buildings.The other product is a “multi­channel” recognition system that uses groups of surveillance(监视) cameras.It can identify individuals in a crowd of up to 30 people within a second. “When people are wearing a mask that covers the mouth and nose, the recognition rate can reach about 95%, which can ensure that most people can be identified，” said Huang, vice president of the company. He added that the system's success rate for people not wearing a mask is about 99.5%. However, the new system struggles to identify people wearing both masks and sunglasses.“In this situation, all of the key facial information is lost.In such cases recognition is tough，” Huang said. People were reacting differently to the new technology.While some citizens have been against using such tools, the majority have accepted the technology as an effective way to decrease crime and catch criminals. [语篇解读]　本文是一篇说明文。主要介绍了一种新的面部识别系统，即使人们戴着口罩也能进行识别。 1．What did the company do to build the system? A．They gathered many face images. B．They employed hundreds of people. C．They spent about a decade building it. D．They merely used the latest technology. 解析：A　[细节理解题。根据第二段中的“The process involved adding a collection of about 6 million unmasked faces and a much smaller collection of masked faces，the company said.”可知，该公司通过收集很多人脸图像来帮助建立该系统。故选A。] 2．According to the text which of the following can be true? A．The new system has already been used by the police. B．The recognition rate of masked faces is about 99.5%. C．The single channel produce can be used at the entrances. D．It isn't hard to recognize people with both masks and glasses. 解析：C　[细节理解题。根据第三段中的“One performs ‘single channel’recognition，which is designed to be used at the entrances to buildings.”可知，单通道产品可以被运用在建筑物的入口处。故选C。] 3．What is the author's attitude towards the new technology? A．Critical.　　　　　　　　 B．Objective. C．Skeptical. D．Optimistic. 解析：B　[推理判断题。根据最后一段中的“While some citizens have been against using such tools，the majority have accepted the technology as an effective way to decrease crime and catch criminals.”以及文章其他内容可知，作者对该系统并没有发表自己的观点，而是以客观的口吻介绍了该面部识别系统，所以作者的态度是客观的。故选B。] 4．Which of the following is the best title for the text? A．Artificial Intelligence and Facial Recognition B．China－the First to Create Facial Recognition C．An Effective Way to Decrease Crime and Catch Criminals D．A New Recognition System to Identify People with Masks 解析：D　[主旨大意题。根据第一段中的“Engineers at the company say their system is the first to be created to effectively identify people wearing face masks.”以及文章其他内容可知，本文主要介绍了一种新的面部识别系统，即使人们戴着口罩也能进行面部识别。所以D项“一种新的用于识别戴口罩的人的识别系统”作为文章的标题最佳。故选D。] B Having a microchip implanted in a man's brain may be common in sci­fi movie plots，but it may soon become an actual possibility. Elon Musk—a US tech mogul (大亨)，founder of SpaceX and co­founder of electric car maker Tesla—has been working on this technology.On Aug 28, Musk gave a livestream demonstration of the chip，which was implanted into the head of a pig named Gertrude. The chip, developed by Musk's company Neuralink, is the size of a coin. But don't let its size fool you.The tiny chip has over 3000 electrodes (电极) attached to flexible threads, which can monitor about 1000 neurons (神经元). It collects neural signals from an area of the brain, and then transmits those signals wirelessly to nearby computers, according to MSN. In the livestream, Gertrude could be seen walking around her pen sniffing (嗅) the ground while a monitor showed her brain activity. Though the technology is still in its early stage, it is encouraging for humans. This technology “would solve a lot of brain/spine injuries and is ultimately essential for AI symbiosis (共生)”， which allows the human brain to merge (融合) with an artificial intelligence, Musk said in previous interviews. When the device can be applied to humans, its main goal will be to help those who have mobility (行动) issues, such as those suffering from paralysis. Musk hopes this technology could also be used to help those with hearing and eyesight issues and one day lead to a cure for epilepsy (癫痫)． Although such a device could, in principle, repair those problems, putting it into practice is by no means a piece of cake.Currently, the device can transmit signals from about 500 neurons in the pig's brain.Compared to 80 billion neurons in a human brain, this number is tiny. And to cover the whole human brain also means the electrodes have to be much smaller. Also, implanting the chip into the brain poses a potential danger. There is a risk of the immune system attacking this foreign body. Right now, the hope of controlling the brain via controlling a few neurons seems overly optimistic.“There are many technological challenges ... to overcome before Neuralink can put its devices to the purposes，” Yuan Lanfeng, an associate professor at the University of Science and Technology of China, told China Daily.
