1 . Last April, Runway AI, a New York company introduced technology that let people make videos by typing a sentence into a box on a computer screen. The several-second videos were not clear.

Just 10 months later, another company OpenAI has developed a similar system that can create videos seemingly from a Hollywood movie. It shows a short video created in minutes: a woman is walking down a street. The technology could speed the work of seasoned movie-makers, but make less experienced digital artists lose their jobs. They call this system Sora.

However, Sora is not perfect. Sometimes, things like shop signs in the videos don’t make sense. Although it is good at getting details right, it can still make mistakes, like making the crowd’s feet look strange in the street video.

Despite (尽管) these challenges, Sora has a lot of possibilities. Models like Sora can change things by making videos in real-time (实时). This can be a big deal for things like video games and help the AI market grow even more. But to make this happen, we need a lot of computing power. Making just one second of video needs a lot of frames (电影画面的一帧), but present models take a long time to process each frame.

The company has not made Sora open to the public yet…

2 . The first emperor of China, Qin Shihuang, is remembered for the many things he did during his rule.

Between 221 and 210 B.C, he started the construction of the Great Wall of China. He built a large network of roads. He introduced a new writing system, currency (货币流通), and set of measurements. The emperor also ordered the construction of a huge army of life-sized terracotta (陶器) soldiers. These, he hoped, would protect his tomb (基) after his death.

Today, the soldiers in Xi’an’s terracotta museum are light brown, but they weren’t always this color. They began as an army of red, blue, yellow, green, white, and purple. Sadly, most of the colors did not last to the present day. Before their discovery, the clay soldiers were protected by being underground. When they were ___▲___, however, the air caused the coating under the paint to fall off. The paint disappeared in less time than it takes to boil an egg, taking with it important pieces of history.

New techniques are now starting to reveal (揭露) the army’s true colors. Scientists have recently discovered an area with more than a hundred soldiers. Many of these still have their painted features, including black hair, pink faces, and black or brown eyes. Chinese researchers have developed a special liquid (液体) to help keep the soldiers’ colors. After they find a soldier, scientists spread the liquid over it. They then cover it in plastic.

Scientists are also finding colors in the dirt around Xian’s terracotta warriors. “It’s important not to move the dirt, so the colors won’t be lost. We are treating the earth as an art piece,” says Rong Bo, the museum’s leading chemist. The next challenge, says Rong, is to find a way to put the colors to the army again. Once that happens, artists can bring Emperor Qin’s army back to life in full color.

3 . ①There are a few ways in which Chinese restaurants are different from Western restaurants. Chinese restaurant culture is broad and profound.

②Consider how Westerners go about eating at restaurants. Everyone always gets their own menu and orders their own food. And, since the tables are usually small, it is quite difficult to talk to—or even see—more than a few people during the meal.

③While in modern China there are many Western-style restaurants, the traditional Chinese restaurant experience is quite different from in the West. Usually, everyone sits at large, round tables where it is easy to see and talk with each other, even if it is a rather large group. One person orders the food for everyone, after considering the likes and dislikes of the other people in the group. Then, when the food comes, all of it is put in the middle of the table. Everyone then serves themselves by taking a small bit of food and putting it on their own plates.

④Just as in the West, people can choose what they want to eat. However, while in the West, importance is placed on the individual (个人) and having one's own preferences, in China importance is placed on sharing and community. Instead of seeing themselves as individuals first, and part of the group second, Chinese people generally see themselves as part of the group first and individuals second. Everyone still gets what they want, but it is a shared experience.

⑤Finally, since people are seated at a round table, everyone is treated equally. No one person is given greater importance over another. However, respect is still shown to older people or people of higher status, as they always sit at the far end of the room facing the door.

⑥China has many different styles of food and a wide range of ingredients and cooking methods. And so, when you are in China, you should make an effort to enjoy Chinese food as much as possible. However, you should also make an effort to enjoy it as the Chinese do-as a group experience-a time for sharing. family, and friendship.

6 . Television is good. You’d like to watch it all day and all night. But too much TV is a very bad thing. Scientists found that kids who watch too much TV may have more trouble learning to read. They can’t focus on (专注于) their work. Kids learn language skills best by reading, talking and playing with others. If they spend too much time watching TV, they’ll have less time for those things. Watching too much TV is bad for people’s health. People don’t move much while watching TV. What’s more, they may eat a lot of food while watching. This can make them fat. We call these people “couch potatoes”.

Fighting on TV is a big problem for kids. Young people are good at following. Scientists have found that those who watch a lot of fighting shows are more likely (可能) to fight.

7 . Many students have fun with their school life. But many Japanese students are unhappy. They have lots of pressure from their family. Most of Japanese students must study hard at school for their parents and for future. So it’s tired and boring for some students.

Japanese students always try their best in school, but sometimes they may fail exams and make their parents lose hope for them. The students may have bigger pressure from both family and the school. So they finally don’t get interested in their schoolwork. In this way, more pressure and problems are waiting for them. That’s really a terrible thing.

According to a report, most Japanese parents would like to send their children to different schools on weekends, but it only helps kids to get good grades. They never mind the students’ healthy development. For example, many school students said they don’t know how to get on well with and how to take care of others. That’s bad for kids’ whole development.

In Japan, many schools usually own their strict rules from hair to clothes. So Japanese students live with great pressure both in school and at home.

8 . No model has ever received more attention in China than the Xiaomi SU7, which was launched (上市， 发行) on Thursday night in Beijing.

It may sound unbelievable but the launch event attracted (吸引) more than 40 million views on Xiaomi Auto’s Weibo alone. Even guessing its price level had been a popular topic on China’s social media platforms for weeks.

Xiaomi, one of the world’s leading smartphone companies, began accepting orders in China through an app on Thursday night, after founder Lei Jun finished a more than two-hour presentation (发布会) on the SU7 car by stating the much-awaited price range (区间): 215, 900 yuan to 299, 900 yuan.

Xiaomi said that it received 50, 000 orders for the SU7 in the first 27 minutes after sales opened at 10 p. m. Beijing time. Lei mentioned that Beijing-based Xiaomi aims to become one of the world’s top five car makers in the next 15 to 20 years. “It’s hard to make a car, but it’s cool to succeed,” he said.

Lei said Xiaomi would lose money on the basic model at 215, 900 yuan, a price that is lower than the Tesla (特斯拉) Model 3 in China. In his opinion, the SU7 car did better than the Tesla in most areas, but the best type of the SU7 is not as good as the Porsche (保时捷) Taycan.

“There’s still a long way to go for our car to become a Porsche,” he said, “but if Xiaomi keeps working hard for another five to ten years, one day we will finally catch up with and even surpass Porsche.”

10 . ①At school, students usually learn many subjects in the classroom like English, math and so on. Now there is a new one in some schools—school gardening (园艺). It is an outdoor (户外) subject. In the gardening class, teachers teach students different kinds of vegetables and how to grow (种) them. Then students work in groups.

②________ Why? Because they can have much fun in this class. They don’t have to sit at their desks in the classroom all day. They can get out, get their hands dirty, do things with their own (自己的) hands and relax.

③It’s also fun to get something to eat and see. In some schools, students like to grow carrots and tomatoes. It’s always interesting for them to get a carrot or a tomato, wash it and eat it right in the garden. In some schools, students like to grow flowers (花). When it’s spring, all the flowers come out and they’re really beautiful. Students like to walk and talk in the beauty. That’s their favorite thing to do after busy hours of work.

④Only fun from the classes? Of course not. Students can learn something, too. Keeping a school garden is difficult and all the students in the group need to come and help. This teaches students teamwork. Also, some vegetables are easy to grow, but others need a long time. This teaches students they need to wait (等待) before they get the things they want.

⑤There may (可能) be many other good things about school gardening. But one thing is for sure—students really love having outdoor classes.
