French doctors and American scientists have reported doing an operation in which the doctor was outside the operating room. This kind of operation is known as robotic operation.
Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France.
A doctor in Strasbourg got the patient ready. He placed medical tools and a small video camera in her stomach area. Doctor Marescaux in New York watched the patient on a video screen. Then he used the computer to send messages to the robot machine. The robot moved the tools that cut the woman’s gallbladder（胆囊）away. The woman got well soon after the operation and left the hospital two days later.
Experts say the main problem with such a robotic operation is based on high-speed telecommunications between the doctor and the robot. Technology must be able to send a doctor’s order to a robot to move the tools quickly.
Experts also say a successful robotic operation will improve an operation. For example, the robot can make much smaller movements than a person can. A robot machine can turn tools in ways that a doctor’s hand cannot.
Doctors say such a robotic operation will make possible safer and better operations in the future. They say it will improve doctor training. It will also mean that doctors could do an operation on people in dangerous places far away. And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work.

【推荐1】In 2023, a popular chatbot(聊天机器人) named ChatGPT could answer science questions and even write poetry! It was like having an online brain to help with homework. However, some schools were worried that students would use it to cheat, so they didn’t allow it.
ChatGPT was made by a company called OpenAI, using something called Artificial Intelligence (AI人工智能) technology. AI makes computers and robots act like they have human intelligence. Some people think using AI to do homework is not a good idea. They say you need to learn how to think and solve problems on your own. Using AI to do all the work means you miss the chance to learn.
Even though ChatGPT can do many things, it’s not perfect. It can make mistakes and sometimes give answers that are too difficult to understand. Some teachers believe the chatbot’s work is too hard for students, so they would be suspicious(怀疑的) if someone handed it in as their own work.
However, some people think that we should learn how to use AI. They say that AI is a part of our world now, and we need to know how to use it correctly.
So, what do you think? Should your school allow AI? Maybe we should learn how to use it to help us remember and grow.

【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 Sating Oval is said to have“the fastest ice”, as 12 new Olympic records and one world record were set there. The secret is the 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 only 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 a 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 iPad and decide 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.

【推荐3】What will our life be like in 50 years? No one knows the answer exactly (确切地), but we are sure that it will be very different from the life today. My brother Jim Green makes some predictions. Here are some of his ideas.
First, people will have less work to do, and robots will do most work. People will use robots to make cars, do the housework, look after sick people and teach students. People will spend most of their time playing sports and traveling. So people will become stronger and healthier, and they will live to be about 200 years old.
Second, cars will become very small and computers will control (控制) their speed. So there will be fewer accidents on the road. Planes will be very popular and most people would like to take them to travel.
Third, people will be able to live in the sea, on the moon or on Mars. The earth won’t be crowded or noisy. So there will be more space for people to plant trees. There will be less pollution, and the air will become much fresher.
Finally, water shortage will become one of the most serious problems. If people don’t save water now, there will be water wars in 50 years.

【推荐1】The first emperor of China, Qin Shihuang, completed a lot of achievements in his rule. Between 221 and 210 B.C, he started the building of the Great Wall. He built a large network of roads. He introduced a set of systems, such as writing, money and measurements. He also ordered the building of a huge army of life-sized terracotta soldiers. These, he hoped, would protect his tomb（坟墓）after his death.
The soldiers today in Xi’an’s Terracotta Museum are light brown, but they weren’t always. They used to be an army of red, blue, yellow, green, white, and purple. Sadly, most of the color did not last to the present day. After being open to air during digging, the coating（覆盖层）under the paint began to fall off. The paint disappeared in less time than it takes to boil an egg.
Now new technological ways are starting to show the army’s true colors. Archeologists（考古）have recently discovered an area with more than a hundred soldiers. Many of these still have their drawings, including black hair, pink faces, and black or brown eyes. Chinese and French researchers have developed a special medicine to help protect the soldiers’ colors. After they find a soldier, archeologists put some medicine onto it. They then cover it with plastic.
Archeologists are also finding colors in the dirt around the soldiers. It’s important not to mess the dirt, so the colors won’t be lost. “We are treating the earth as a treasure,” says Rong Bo, the museum’s leading archeologist, “the next challenge 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 colors.”

There is probably no better symbol of spring than flowers. The peach blossom is one of those seasonal flowers. It usually blooms (开花) in March and April.
Pinggu district in Beijing, Nanhui County in Shanghai and Longquan Mountain in Chengdu are all good places to enjoy the beautiful peach blossoms. But if they are not special enough for you, you can go to Nyingchi (林芝) in Tibet. There you can see a sea of pink at the foot of snow-covered mountains under a blue sky. The peach blossom, with its beauty, has won the hearts of visitors and many Chinese poets and writers. From China’s first book of poetry, the Classic of Poetry (《诗经》), to the many poems of the Tang Dynasty, the peach blossom usually has to do with beautiful young ladies. As one famous poem goes:
This very day last year, oh, at this very place,
A pretty face outshone the flowers of peach trees.
I do not know today where shines the pretty face,
Only the pretty flowers still smile in the vernal breeze.
The peach blossom makes people think of a shy woman blushing (脸红). Because of this, the peach blossom is related to romance (浪漫) in China. And if your eyes are the shape of peach petals (花瓣), you have a pair of “taohuayan”. And you probably have peach blossom luck.
1. We can enjoy peach blossoms in Longquan Mountain in Chengdu in March and April.
2. The peach blossom has something to do with handsome young men.
3. The writer quotes (引用) the poem in the passage in order to show the popularity of peach blossoms.
4. Chinese people believe if you have a pair of eyes in the shape of peach petals, it means you may be lucky in love.
5. The passage is mainly about the introduction to peach blossoms.
【推荐2】A middle school organized a “No TV Week” program. All the teachers, parents and students worked together for this program and most of them found it to be a very good one. The headmaster said, “The idea was not to stop watching TV completely but for the students just to find how much time they watch TV and try to use the time for other things.” What did the students say about this “No TV Week”?
