It has become such a necessary part of modern life that many people cannot imagine a day without it. While it brings great convenience, the future popularization of smartphones also causes heated discussion about its influences on people’s life, work and health. Smartphones greatly improve efficiency. With one device, people can complete online payment, real-time navigation, video calls and remote office work. In the future, smartphones will further break the boundary between the virtual world and reality. AR technology will allow users to try on clothes, view 3D models or receive navigation information directly on the phone screen. Students can use AR functions to learn abstract knowledge, which will greatly change classroom teaching styles. However, experts warn about the hidden costs. Many people suffer from sleep loss because they stay up late scrolling through phone screens. Constant interruptions from messages reduce people’s focus and productivity. Some research shows that heavy smartphone users may have weaker ability to concentrate on long-time tasks. Besides, the biometric information stored in phones, such as fingerprints and face data, faces possible safety risks. Hackers may steal private information if the system is not well protected. Manufacturers are trying to solve these problems. They are developing healthier screen settings to reduce eye strain and stronger encryption systems to guard personal data. Environmental groups also push producers to design recyclable phones, to cut down electronic waste. Smartphones will continue to develop rapidly in the coming years. It is not the technology itself but the way humans use it that decides whether it benefits us or harms us. The future calls for a balance between enjoying convenience and controlling its negative influences. 1. What can AR technology on future smartphones help people do? A.

Unlike traditional cars controlled fully by human drivers, smart cars depend on sensors, cameras, LiDAR and powerful onboard computers to observe the road and make driving decisions. LiDAR sends laser pulses to build 3D maps of surroundings. Radar detects the speed and distance of nearby cars even on rainy or foggy days. Cameras recognize traffic lights, road signs and pedestrians. All these devices collect real-time information and send it to the car’s computer. Within milliseconds, the AI system analyzes the situation, predicts possible dangers and controls steering, braking and acceleration. Nowadays, most smart cars on roads are semi-autonomous. They can assist drivers with lane keeping, automatic parking and emergency braking, but human drivers still need to watch the road and take over control when necessary. Fully autonomous cars, which need no human attention at all, are still being tested. Engineers carry out tests in many cities to improve the system’s ability to deal with unexpected situations, such as sudden roadblocks or jaywalking pedestrians. Smart cars are expected to bring huge changes. First, they can reduce traffic accidents, since most accidents are caused by human mistakes like tired driving or careless operation. Second, they can improve traffic flow and cut down jams. The elderly and disabled people who cannot drive will also get easier access to transport. However, smart cars face many difficulties. Bad weather may weaken sensors. The legal responsibility after accidents, data privacy and high production costs remain big problems. Before fully autonomous cars widely enter public life, engineers, policymakers and researchers still have a long way to go. 1. Which of the following helps smart cars work well in foggy weather? A. LiDAR B. Radar C. Cameras D. Onboard screens 2. What is the main idea of Paragraph 3? A. The differences between semi-autonomous and fully autonomous cars. B. The common causes of road traffic accidents. C. Rules for testing smart cars in big cities. D. How human drivers control traditional cars. 3. What is the purpose of the text? A. To explain how smart cars work and their prospects and challenges. B. To persuade all drivers to buy self-driving cars right now. C. To compare smart cars with traditional cars in prices. D. To describe traffic rules for autonomous vehicles. 4. Who is the intended reader? A. Teenage learners exploring future transport technology. B. Professional car software developers. C. Traffic police responsible for road safety. D. Lawyers studying traffic accident laws. 【答案】1.B 2.A 3.A 4.A 【解析】 1. 细节题。原文 “Radar detects the speed and distance of nearby cars even on rainy or foggy days.” 2. 主旨题。第三段介绍半自动驾驶（需要人监控）和全自动驾驶（仍在测试）。 3. 写作目的：讲解智能汽车工作原理、好处与现存挑战，没有推销、比价或讲解交通法规。 4. 目标读者：科普说明文，面向学习未来交通科技的青少年，不是程序员、交警、律师。 Passage 4 Smart Cars: Reshaping Future Urban Mobility 改编自 Sage Reference, Encyclopedia of Transportation: Social Science and Policy - Smart Cars As cities develop rapidly, traffic jams, carbon emissions and limited parking space become serious headaches. Smart cars are considered a key solution to future urban transport. Connected with the city’s traffic network, smart cars can communicate with each other and road facilities, creating a smarter traffic system. One important feature of smart cars is vehicle-to-everything communication, or V2X. Smart cars can exchange information with traffic lights and roadside sensors. They know the real-time traffic condition ahead in advance and choose the fastest route. This will reduce unnecessary stops and cut traffic jams greatly. Besides, most future smart cars will use clean energy such as electricity, lowering carbon pollution and helping build environmentally friendly cities. In the future, people may not need to own private cars. Shared smart cars can be ordered through mobile apps. After sending passengers to destinations, the cars can drive themselves to pick up the next user or find parking spots automatically. This model will reduce the total number of cars on city roads and save large areas for parking lots. The elderly and disabled can enjoy convenient travel without learning driving skills. Even so, smart cars cannot be widely used overnight. Safety is the top concern. AI systems may fail to deal with rare and complex road conditions. Privacy risk is another worry: smart cars collect large amounts of location data and travel records. If the data is not properly protected, users’ personal information may leak. Governments around the world are making new rules to manage autonomous vehicles and clarify responsibilities when accidents happen. Smart cars will not completely replace traditional vehicles in the short term. But step by step, they will reshape how people travel in cities, changing the whole pattern of urban mobility. 1. What can V2X technology help smart cars do? A. Stop carbon emissions completely. B. Communicate with traffic equipment to avoid traffic jams. C. Repair damaged sensors automatically. D. Remove all private cars from city roads. 2. What is the main idea of the text? A. The advantages of shared smart cars and problems to be solved. B. The history of electric vehicle development. C. Ways to cut down city parking space. D. Different kinds of energy for future cars. 3. What is the author’s purpose of writing this passage? A. To prove that traditional cars will disappear soon. B. To introduce how smart cars will change city transport and related challenges. C. To teach readers how to order shared smart cars with apps. D. To criticize city traffic management systems. 4. Who is the intended reader of this article? A. High school students learning about future technology. B. Urban planners designing city transport systems. C. Car salesmen selling electric vehicles. D.
