【推荐1】Now many people go to work and school on buses, trains and bikes. However, some people dream of a day when they can fly in the sky.

In Singapore, a company has showed a flying taxi. When some people travel in flying taxis, there will be fewer cars on the roads. It can be less crowded. In the 3D space of the sky, cars could move around each other without bridges or roads. The taxis can also take off and arrive on rooftops. That will save parking space on the ground. And flying is fun. It’s cool and interesting to fly in the sky every day on the way to work.

However, some people don’t like flying cars. A famous scientist has a rocket company and a car company. It seems that he can make flying cars, but he says, “If the sky is full of flying cars, it will be noisier. Something may fall on people’s heads more easily. It’s dangerous.” He thinks it’s much better to build lots of tunnels (隧道) underground.

Are flying cars or taxis a good idea? Shall we find other ways to solve the traffic problems?

【推荐2】AI model Sora surprises the world

Meet Sora, the cool model from OpenAI. It can turn your words into videos like magic (魔法)! Just tell Sora your idea, and watch it make a video right before your eyes.

How good is it?

Videos made by Sora look good on both computers and smartphones. Sora can also make videos with lots of people doing different things with clear details (细节). It also knows how things should look in real life.

How does work?

Sora looks at many videos and learns from them by breaking them into very small pieces. It uses these pieces to make a new video. The new video is gray at first and very messy (乱糟糟的) —you can’t tell what’s in it. Then, Sora fixes the video until it looks good and smooth.

Sora also gets help from ChatGPT. It turns the user’s short sentences into clear instructions (指令). This helps Sora make the video just as you asked.

Is it good enough?

Sora may find “busy” pictures hard to understand. For example, when a person moves, things around them change (变化). Sora may not be able to tell “left” from “right” and mess up a person’s leg moves.

The 19th Asian Games was held in Hangzhou, China in 2023. It was the largest and most technological Asian Games. The Games included many kinds of cutting-edge(前沿的) technologies to make players and watchers have safe and enjoyable experiences.

	Facial recognition(人脸识别) technology was used to know about players and officials in order to make sure that only related people can enter Asian Games Village. The facial recognition system was connected with the event’s safety systems, allowing for a safer environment for all players.
	Drones were used to learn about the event, both on and off the field. The drones were fixed with cameras and sensors (感应器) to provide a full view of the event for the watchers who watch the game on TV. The drones were able to notice any activity, as well as provide real-time events.
	VR (Virtual Reality) was well used in every area of the Asian Games. With a pair of special glasses, players can train and compete in a virtual (虚拟的) world instead of going into the field. For watchers, it provided a chance to experience the players’ real training. All the people with VR glasses can enjoy the games in different places.

【推荐1】Would you like to live in a city where buildings turn the lights off for you, and self-driving cars will find the nearest parking space themselves? Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think.

Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence system (远程遥控系统)”—allowing users to control the heating and locks, take part in video meetings, and receive education, health care and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.

The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.

About 75% of the world’s population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener,” said Dan Hill, head of a research company.

It’s not a dream that every home will have a robot. We believe that there will be robots in people’s homes.

Now, robots are able to help people do the housework. They can also help doctors do difficult operations, play chess with people, play the piano and do some other things.

It is really funny to have a cooking robot. It can cook all the dishes on the menu. What you only need to do is just to wait for two to four minutes. You’ll be surprised at how delicious the food will taste.

In the future, the robot will be a nurse, a guard or a partner in your life. Robots will become part of the family, and provide close service for people. We all look forward to the new robot age.
