老师：Hello everyone, this is Sharon. Welcome to my class. This is the project part of Unit 4. By the end of this section, you are expected to achieve these goals. At first, you need to design a high tech product of the future through cooperation and exploration. Then you are supposed to use group work to make and present a product description. Finally, you must learn to evaluate and comment on each other's work.
老师：Actually, I came close to being late for this class today because of the heavy traffic. Do you have similar experience due to the crowded roads in the city? How can we solve the problem? Can you imagine the mobility in the city tomorrow? Now let's enjoy a short movie together. Meanwhile, you can think about some advice you may offer to our government. Now, let's start.
学生：Cleaner, more flexible, with efficient use of space. In light of smug and traffic chaos in many cities, there's a need for redesigning sustainable mobility. But what does mobility of the future look like? The car of the future will drive itself, leaving people free to read the newspaper, work during the trip. It can also find the next available parking spot all on its own and come back when it's summoned. At the same time, network cars will communicate with each other and be able to give warning about potential hazards.
学生：Charging cables are a thing of the past. Instead, electric cars of the future are able to get power from charging points built into the asphalt. The car just needs to drive over a slab in order to start the inductive charging. The energy is transmitted to the car's battery by a magnetic field between two coils, one located in the floor of the car and a second one in the asphalt slab under the car.
学生：Instead of fixed traffic lights and painted on pedestrian crossings, the Intelligence City automatically analyzes sensors located in places such as cars, cars and public transit vehicles. It can tell, for instance, where a pedestrian wants to cross the street and then project the necessary signals. There can also be variable speed limits and detour suggestions that appear on the road in order to help keep traffic flowing. Public self driving capsules operate like a taxi on rails, allowing for personalized routes on public transportation. There are no fake schedules. The capsules are just ordered via smartphone. When needed, without having to lift a finger, passengers will be whisked to their desired destination by these innovative vehicles.
学生：Future mobility will also transform metro systems. Turbo pods will automatically carry passengers at enormous speeds through a system of tubes which minimize friction and aerodynamic drag. These systems use their propulsion energy extremely efficiently. Once accelerated to its peak speed, the part just cont
