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.

【推荐1】Cars make our lives convenient, but they can also be a problem. To improve the environment, many countries are developing electric vehicles (EVs). Among them, China is taking a leading role and has created the world’s largest EV market.
Last year over 40% of the 753,000 EVs in the world was sold in China. That was more than twice as those sold in Japan. Chinese young drivers are big fans of EVs. Some Chinese companies are among the top in the world’s EV sales.
“Charging an electric car is cheaper than a car with gas,” said Wu Hao, a driver who bought an electric car this year.
However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can’t go far before needing to be recharged. Some of these problems are being solved. But we still need more charging piles in some places.
China promised to stop increases carbon dioxide emissions (碳排放) by 2030. Developing EVs is one of many effects China has made to reduce pressure on its environment. As China goes, so will the world car industry.

The Chang’e 5 robotic probe(探测器) has become China’s first spaceship to bring the country’s national flag to the Moon.
The scene of the Five Starred Red Flag against the dark sky on the grey lunar surface was taken by a camera on the Chang’e 5 robotic probe’s lander and then sent to the ground control. In Chang’e 3 and 4 tasks, the national flag was painted on the spaceship. Therefore, the flag carried by Chang’e 5 is the first Chinese national flag that has been planted on the Moon.
The system to raise the flag was designed and produced by engineers at China Space Sanjiang Group in Hubei Province. It has three parts.
Because of the strong radiation(辐射) and the terrible temperatures on the Moon, we couldn’t use traditional fabrics(面料). If we place an ordinary flag on the Moon, its colors will quickly become lighter. Designers spent more than one year choosing and testing ideal materials, and finally picked a new kind of material that can resist the very difficult conditions on the Moon.
1. Chang’e 3, Chang’e 4 and Chang’e 5 all brought the Chinese national flag to the moon.2. The flag raising system includes three parts.
3. If we place an ordinary flag on the Moon, its colors will quickly become dark.
4. The main idea of the passage is about the first Chinese national flag planted on the moon.
【推荐3】Space tourism is not all about rockets—space balloons can do it too! The Spanish company HALO Space had the first unmanned test flight of its balloon in December 2022. It will compete with several other companies in the space-traveling business.
The test lasted 4 hours. The balloon reached 37 kilometers above Earth. People would see Earth from the blackness of space, said the Daily Mail. By 2029, the company plans to carry 3,000 passengers on 400 trips a year. The ticket for each trip will cost between 100,000 and 20,000 US dollars (about 696,000 to 1,392,000 yuan).
The test balloon is 773 kilograms, with a diameter (直径) between 110 and 130 meters (the length of a soccer field). It is filled with hydrogen (氢气), which is much lighter than air. When it flies, it lifts the capsule (舱) connected to it. The capsule can carry eight passengers and a pilot. Passengers can enjoy the360-degree view through the big windows. To ensure people’s safety, the capsule is also equipped with parachutes (降落伞). Another company, the US-based Space Perspective, said that such trips are about relaxation. Their balloon rises slowly at about 300 meters per minute, and takes about two hours to fly to 30 kilometers. Space Perspective is planning to fly their balloons from ships on the sea. Then people can enjoy sunrise and sunset there!

【推荐1】Do you know ChatGPT? It’s an artificial intelligence (AI, 人工智能) tool (工具). It can answer questions, tell stories, and do much more. But it’s very “thirsty (渴的)”, said a new study.
ChatGPT has “homes” around the world in data centers (数据中心). When it works, the computers at the data centers get very hot. Workers then have to use water to cool them down.
Cold water goes into pipes (管道) near the computers. The water needs to be very clean. They can’t use seawater because it can eat away at the pipes.
When you ask ChatGPT 20 to 50 questions, it “drinks” 500 milliliters of water. Scientists used 700, 000 liters of water to build ChatGPT. The water use is very big. People can make 370 cars with it.
ChatGPT is just one AI tool. You need data centers to do everything on the Internet. There are more than 8,000 data centers around the world. The number is still growing. We may have to “fight (斗争)” with AI for water in the future (未来).
1. What do we know about the data centers in Paragraph 2?a. They are AIs just like ChatGPT.

【推荐2】About 30 years ago, Nissan introduced the world’s first “talking car”. Actually, it was just a recorded voice that would tell you that your door was open and would continue talking to you until you closed it. Of course, it never caught on. Only a few people knew about the car.
Times have changed and the talking car of the near future is a car that you can talk to, rather than a car that talks to you. You’ll be able to control your radio by giving voice orders. And you can get traffic reports or directions, and send or receive emails in the talking car. To do all these, you needn’t push a button at all.
This is good news for those who spend more and more of their lives in their cars. In fact, the new type of cars will be more like offices on wheels because it has computers, wireless Internet and satellite radio inside. Companies are hoping that time wasted in traffic could be put to better use. If workers are able to check their e-mails, faxes, and meeting time on the way to work, they can spend more time at the offices doing more important tasks.
Microsoft, of course, is hoping that every one of those mobile offices will use Windows. “It’s a great goal.” says Dick Brass, VP of Microsoft’s automotive division (汽车部门). “But we’d like to have one of our operating systems in every car on earth.” There are already 650 million cars in the world, and every year about 50 million new cars roll off the production lines. If Brass’ wish came true, cars could become a bigger business for Microsoft than computers.
1. The underlined phrase “caught on” in paragraph 1 probably means ________.| A．became expensive | B．drove down | C．became popular | D．broke down |
| A．The talking car of the near future is a car that talks to you. |
| B．It was introduced in the late 20th century. |
| C．It could record voices. |
| D．It could not only record but also talk itself. |
| A．traffic reports | B．voice orders | C．light signals | D．electricity energy |
| A．their workers will get to the office earlier |
| B．much time will be wasted in traffic |
| C．their workers will check e-mails, faxes and meeting time at home |
| D．their workers will have more time to do more important work at the offices |
【推荐3】In recent years, many schools in China have had high-tech products. They add value to student learning and life at school.
At the Tianjin Eco-City School, the high technology makes learning a fun experience. In aerospace (航天) classes, students use VR glasses to learn about what’s inside a rocket and how it is launched (发射) in a computer game. Also, in swimming classes, by wearing smart earphones, children can get real-time commands from the coach under the water. It helps improve the quality of training.
For PE classes, Yuwen School in Wuhu, Anhui, has used self-testing tools with AI technology for activities. Students can get voice reports and results on how they did right after each exercise. They can also see which parts of their exercise need improvement.
Apart from learning, students can also enjoy meals made by smart canteens (食堂). To meet the different needs of students, the canteen offers over 400 dishes, with six to seven choices for each meal. Parents and students can choose their favorite before meals online. And they use facial recognition technology to pick up their meal. It helps the school plan and prepare meals cutting down on food waste.

Washing clothes is easy for most people living in cities, as washing machines do the job. However, in many poor areas, people have to wash their clothes by hand, as they don’t have electricity or money to buy the machines. Now, a new bamboo washing machine might help them solve this problem.
The machine is as simple as the traditional washing machine. However, it uses the natural flow of water instead of electricity. It has a wooden rotation shaft (转轴) in the center and a bamboo drum (桶) outside. You just put the machine in a river and water will go into the bottom of the machine and rotate the main drum. This creates an eddy (涡流) that cleans clothes.
Pan Cheng, one of the designers, said, “There are 836 million people living in extreme poverty (极端贫困) in the world. They have to spend lots of time and energy doing little things like washing clothes. We want the bamboo washing machine to help them free up their time so they can do more meaningful things, like fighting poverty.”
“The best thing about this machine is that it’s cheap and easy to make,” said Yu Yue, another designer. “We give people the rotation shaft and teach them how to set up the machine. They can find bamboo locally and make it into drums. If there is no bamboo, they can also use materials like wood.”
The designers said they spent more than half a year working on the machine. They had countless team meetings and changed their design at least four times. But in the end, they were happy with the results.
1. The bamboo washing machine was created for people who ________.| A．live in big cities |

【推荐2】How do you like movies? As for me, movies are full of interesting people, moving stories and answers to everyday problems. I also like the music and pictures of movies. You have a bad day of problems, just watch a sad movie and you may find that your problems are not so bad.
While I use movies to do with problems in my life, I have a chance (机会) to see life from different ways. We have busy lives, buy different clothing, cars and go to different schools. All of us are from different backgrounds (背景). Some are rich, but some are poor. Some have good jobs, but others don’t. Movies let us think about what life was like in the past, understand the present (现在) and think about the future. Other things don’t let you do this better than watching a movie.
I love all kinds of movies, of course I have my favorites, like Escape Room, The sound of music, Titanic and so on. I also like to watch movies with my family. And tell them what I like.
So, pick out your old favorite movie, or watch a new kind of movie. You can also watch one with your family. Get happy, get sad or get worried and cry if you have to. But just remember this: Life is your movie, try to be a winner of life.
