With 5G, cars like this may soon turn into reality.Finland’s “robot buses” are a good example. Telecoms (电信) company Nokia has installed (安装) 5G transmitters (信号发射器) in 15 lampposts (路灯柱) along a 1-km road. These transmitters are able to control (控制) the buses, making them driverless, according to Raconteur Media.There are also 5G roads. These roads would also have many 5G transmitters. They can provide smart services, such as telling you where the nearest gas station (加油站) is. These roads could also be used to control traffic. “Transport bodies will be able to manage a road network (网络) in real time, controlling traffic lights, traffic flow (车流) through computer programs,” said Guy Matthews, director at CGI UK, a tech consultancy company.Public transportation can also benefit (受益) from 5G and smart tech. In the South Korean city of Seoul, a smart management system has been set up in one of the city’s subway stations. This system has many advanced features (功能), including a 3D map, sensors (传感器) and an advanced camera system that make the station more efficient and safe, according to Arirang News.And of course, there are driverless cars. These cars can send signals (信号) to each other. They also “talk” to traffic lights and road sensors. 5G will allow these cars to drive more safely (安全地) because they can communicate with each other, as well as with traffic lights and road sensors.31．What does the underlined phrase “reality” mean?A．幻想 B．科幻 C．现实 D．小说32．________ can control the buses.A．5G transmitters B．LamppostsC．Gas station D．Sensors33．5G roads can be used to________.A．provide smart servicesB．tell people where the nearest gas station isC．control trafficD．All of the above.34．Which of the following is true according to the passage?A．5G is not smart sometimes.B．5G can improve traffic safety.C．5G cannot be used in public transportation.D．Driverless cars cannot communicate with each other.35．What’s the passage mainly about?A．How to control traffic.B．The invention process of 5G.C．Application of 5G in transportation.D．The disadvantages of 5G.C【语篇来自二十一世纪学生英文报·试题原创】Facing our futureThe face is usually the first thing you notice when looking at someone. Everyone has something about their face that’s a little different. And that little difference makes facial recognition possible.You can find this technology in many popular films. In the sci-fi classic 2001: A Space Odyssey, a powerful computer is able to “read” the emotions (情绪) of astronauts by scanning (扫描) their faces. And in the 1987 action film Robocop, a cyborg (半人半机器) police officer identifies (识别) a criminal by scanning his photo on a computer.Today, facial recognition tech is no longer just in films. It has been used as a security measure (安保手段) or to identify threats (威胁).For example, in 2018, facial recognition technology helped identify and catch criminals who were attending concerts by Hong Kong singer Jacky Cheung. And if you use a recent model of Apple’s iPhone, you can unlock the phone with your face. But these are just a few of the things we can use facial recognition for. The possibilities (可能性), it seems, are endless (无尽的).Grab, a ride-hailing (叫车服务) company in Southeast Asia, is developing facial recognition technology that can keep passengers safe. The technology works by scanning both the driver’s face and the passenger’s face. This way, passengers can be sure that their driver is the correct one.Retailers (零售商) are also looking to facial recognition technology to drive (促进) business. With the technology, retailers are able to “see” what their shoppers are actually looking at in stores. Later, they use this information to provide suggestions (建议) for customers in the future.36．A powerful computer can “read” the________ of astronauts in 2001: A Space Odyssey.A．emotions B．information C．dreams D．heights37．The cyborg police officer identifies a criminal by________.A．scanning his ID card B．scanning his photoC．searching for his information D．tests38．Grab develops facial recognition technology to________.A．keep drivers safe B．count the number of carsC．limit the number of passengers D．keep passengers safe39．With the facial recognition technology, retailers can________.A．sell more productsB．see daily salesC．provide accurate suggestions for customersD．choose better goods40．According to the passage, the facial recognition technology can be used to________.A．capture criminals B．capture emotionsC．promote products D．All of the above.D【语篇来自二十一世纪学生英文报·试题原创】 ‘Seeing’ for those who cannotTwo eighth graders from Austin, US, have created a “smart cane (拐杖)”. It helps people who are visually impaired (视力受损的).Ahyan Hassan and Hasan Rizvi made the cane for a school science competition. The cane has sonar sensors (声呐传感器) that “see” obstacles (障碍物) up to 1.5 meters away. This design won first prize in the competition. “We put blood, sweat and tears into this. We were really excited to win,” Hassan told local newspaper KXAN News. The boys have been best friends since the third grade. “We have lots of similarities (相似点). We both like science and have curiosity (好奇心) when it comes to things,” Hassan explained. “When we see something, we always want to know how it works or why it works.”Their idea came from the old canes of Rizvi’s grandfather. “My grandfather is almost blind and has bad legs,” Rizvi said. “It’s hard for him to get from place to place.”So the boys added some sensors at the bottom of a cane. When they “see” things, they send information to the cane, which can then shake to remind the user. “I hope this inspires (激励) other people to think outside the box, and that’s my goal,” Rizvi said. “It would be amazing if one day what I made became an actual product that I could see people using,” Hassan added.Both boys hope to become engineers when they grow up. They also plan to improve their product to compete in more science fairs in the future.41．Ahyan Hassan and Hasan Rizvi created a________ in a school science competition.A．robot B．smart cane C．sensor D．third42．The design of the smart cane won________prize in the competition.A．first B．second C．third D．no43．The idea of the smart came from the old canes of ________.A．Hassan’s father B．Hassan’s grandfatherC．Rizvi’s father D．Rizvi’s grandfather44．The sensors are________ the cane.A．on the top of B．at the bottom of C．beside D．in the middle of45．How does the smart cane remind the user of obstacles(障碍物)?A．It makes a sound.
