Imagine a world where air pollution is no longer a problem. Clean air is all around us. People don’t have to worry about polluting the air 164 every time they drive their cars. They no longer need to face the problem of not having enough fuel either.
Although scientists have been trying for many years to develop a new kind of car that does not need gasoline (汽油), they have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity. This is the famous hybrid car. This car gets its name from the fact that it has a gasoline engine (引擎) and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars.
Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.

Today, cities are getting bigger and busier. This gives us challenges. We need better transport to get around and clean energy to power our homes.
A smart city can be a bit like a big, clever robot. It can “think” and make decision s to make everything work in a smart way! For example, the bins “tell” the garbage trucks (垃圾车) when they are full. The buildings can “talk” to computers to help save energy. So we need different technologies to make these things come true.
Imagine when you are close to your home, your smart watch tells your home to turn on the lights. Internet of things can help to do this.
Sensors (传感器) are like a city’s eyes. They are in every corner of the city.
| A．How can we live in a smart city |
| B．How can we live more conveniently |
| C．It connects everything to the Internet |
| D．They work together to make a city smart |
| E．They collect data on people and environment |
| F．We know online maps like Baidu Map and Gao de Map |

【推荐2】The Beijing 2022 Winter Olympics were more than a sporting event. They were also a show for science and technology. They are helping athletes (运动员) become “faster, higher, stronger” and offering you a great game-watching experience with the support of 5G. Let’s look at some technologies behind the Beijing Winter Olympics.
The fastest ice
The National Speed Skating Oval is said to have “the fastest ice”, as 12 new Olympic records and one world record were set there. The secret is new ice-making technology. Liquid carbon dioxide (液体二氧化碳) is put under the ice to keep temperature changes on the ice surface in half a degree. That keeps the ice a level surface and it is easier to skate on.
“Seeing” the wind
In events like freestyle skiing and ski jumping, the direction and speed of the wind can have great influence on an athlete’s performance. A Chinese research team developed a system to measure wind. The system uses AI technology. It allows athletes and coaches to “see” wind with real-time data (数据) on their Ipads, and decided when and where to jump.
High-speed cameras
During the speed skating race, athletes can reach speeds of up to 18 meters per second. To catch every exciting moment of the competition, Lie Bao has been used for the event.
Lie Bao, is a 4K high-definition (高清) camera system developed by China Media Group (CMG). It can record speeds of up to 25 meters per second. It closely follows the athletes’ movements and catches different scenes during speed skating, according to Shanghai Plus.

How has technology changed the way we watch TV?
Watching TV shows has become the most popular activity. A survey points out that people have many ways to watch shows besides cable TV. They include smart phones, computers, and tablets. Technology has not only changed where but also how we watch TV. Streaming (流媒体) networks have helped viewers watch their favorite shows when it’s most convenient for them.
Binge-watching (刷剧) has become a new trend. Without having to wait for next week’s episode (集), viewers can watch the whole season in a day, or at whatever pace (速度) they choose. In the US, content (内容) providers also release a choose-your-own-adventure movie, where your choices can affect how the story ends, an idea not possible before with traditional TV.
