Over 5 million shared bikes in China are using services offered by Beidou Navigation Satellite System. These shared bikes all use Beidou-based positioning chips.
The chips have high qualities. They can deal with information accurately and quickly. They provide a better user experience and easier management for the local companies. Now, several new models of shared electric bikes with Beidou-based chips have also started to be produced and put into market. Besides positioning and navigation, the chips will help users and bike companies record user speed and battery condition of an electric bike. The possible crimes during the bike using will also be recorded.
In fact, years ago, shared bike companies began to use positioning chips which worked well with both GPS and Beidou services. After the Beidou system became completely in use in the summer of 2020, shared bike companies started to install Beidou-based chips on more bikes in more areas. The latest chips which are popular with bike companies are smaller and have more advantages over the old types.
Since 2000, a total of 59 Beidou satellites have been sent into space from the Xichang Satellite Launch Center in Sichuan Province. After the final satellite was sent in 2020, the system was completed and started providing global services. Beidou Satellite System is designed and developed by China. China has built the BeiDou Navigation Satellite System (BDS) into a top-class system with cutting-edge technologies, pioneering design and powerful functions, according to a white paper published on Friday by the State Council Information Office. It is one of four global navigation networks, along with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo.
According to a research in 2022, by the end of 2021 the total value connected with satellite navigation and positioning services in China was 469 billion yuan, a 16.3 percent increase year on year. More than 500,000 Chinese people now work at around 14,000 China’s companies and organizations doing business connected with Beidou and other satellite navigation and positioning services.

①Memory is the ability (能力) to remember things. A good memory can help us do better in school, such as language-learning. A few people are born with amazing memories, but most people need to improve their memories by practising. Here are some secrets (秘密) about memories.
②We can still remember things happened in our childhood (童年) but not those last week. In fact, if the things have strong connections with our feelings in our mind, we can remember them longer. When things happen for the first time, children often have strong feelings. Also, parents tell us the interesting or funny stories from our childhood again and again. As a result, we remember them much better.
③It’s natural for common people to forget the new words which they learnt yesterday. Hermann Ebbinghaus wrote a book called Memory and showed a famous forgetting carve. According to him, the quickest loss (失去) of memory happens during the first two days after learning. That means going over what we’ve learned during this time can help us very well to remember the information.
④A 15-year-old sometimes forgets things, but that doesn’t mean his or her memory is getting worse. Our memory gets the top at the age of 25. At that point, we can remember over 12,000 pieces of information in a minute. But after this age, the brain (大脑) starts to get smaller. By middle age, our memory is much worse than when we were young.
1. Why is it easier to remember things in our childhood?a. Because they were special. b. Because we got strong feelings from them.
c. Because they were helpful. d. Because we heard them many times.

All aboard! Let’s take a ride on the world’s highest railway—the Qinghai-Tibet Railway. Sit back and enjoy the journey. Get ready for the trip of a lifetime.
We’re leaving Qinghai Station. The scenery along the way is some of the wildest in all of China. You’re your eyes open as we go through this beautiful land. You may see some Tibetan antelopes (藏羚羊) from your window.
Before we begin our journey, let’s learn about this fantastic railway. It’s truly one of the great engineering buildings of the 21st century. When it was completed on July 1st, 2006, the Tibet Railway set nine world records (纪录), like the world’s highest railway at 5, 072 metres above sea level, the world’s highest tunnel at 4, 905 metres, and the longest tunnel ever built on permafrost (冻土).
As we travel higher, the air gets thinner and thinner. Soon there will only be 50% to 60% of the oxygen (氧气), but don’t be afraid, Each railcar has two oxygen systems (系统). One system gives oxygen in the train all the time. And each passenger can also get a personal oxygen mask just like those used in planes.
Here are a few more things to think about as our train leaves the station. The workers solved three main problems when building this great railway. First, the high altitude (海拔) made the building difficult because there was no enough oxygen. Then, much of the railway runs across permafrost. It’s a kind of ground and keeps changing when the weather warms and cools. Finally, the railway goes through some of the most sensitive ecology (敏感的生态环境) in China. Great care was a must to make sure of the smallest influence on nature.
All three problems were met, making our trip come true. All aboard! The train to Tibet is leaving in fifteen minutes.

①A Turkish proverb says. “The more languages you know, the more people you are!” There are about 35 languages spoken in Turkey, but 90% of the people speak Turkish.
②Turkish uses an alphabet that is not strange to many English speakers, but when you look at Turkish spelling, you may find it so difficult. There are 29 letters in the Turkish alphabet and six of them—c, g. t, ō, s and ü—aren’t in the English alphabet. For example, all those marks in a word like gūnes gōzlügü (“sunglasses”) can really daunt you!
③But luckily, Turkish pronunciation isn’t always as hard as it seems. In Turkish, each letter is pronounced only one way. So it can become quite easy to pronounce a new Turkish word.
④Turkish is an agglutinative language. That means it puts pieces together to make words. In Turkish, this practice can make some very long words. You can add suffixes to most Turkish root words. For example, the word ev means “house”. Add the ending ler to make evler, “houses”. Then add den, meaning “from”, to make evlerden, “from the houses”. Or add li, meaning “having” and you get evli, “having a house”. The suffix ci can mean “one who does something”. Gazete is “newspaper”; gazeteci means “a newspaper writer”.
⑤There are more facts about Turkish for you to learn. You’ll find that learning about it helps open up door to a different culture.

In China, people play lion dances on big days like the Chinese New Year, because they think the lion dance can bring good luck.
The lion dance started in China over 1000 years ago. In the Han Dynasty*, people from Central Asia gave lions as presents to the Chinese king. In the Three Kingdoms Period*, people began wearing lion-like clothes to celebrate festivals. It was the first lion dance. In the Tang Dynasty, it became more important.
In China, there are two kinds of lion dances - the Northern kind and the Southern kind. The Northern lion is red and yellow, and it looks dangerous, like a real lion. There is usually a father lion, a mother lion, and sometimes little lions in the Northern lion dance. The Southern lion is like a cat and it has more different colours.
The lion dance needs one man dancing the head and the other man dancing the tail. But in the Northern lion dance, there’s a dancer with a ball standing before the lion. The Northern lion dance is usually for fun, and the music is lively. The music of the Southern lion dance is exciting as well.
The lion dance is always a great art for people all over the world and the value* of it never changes* over time.

Cathy Hackl’s son wanted a party for his 9th birthday. He wanted to hold the party on Roblox, a website where users can play and create games. Roblox is part of the metaverse. This is a virtual-reality space. There, users can interact with other people and digital environments. Virtual reality is a three-dimensional simulation of a real-life image or environment. “They hung out and played, ” Hackl said, “Just because it happens in a virtual space doesn’t make it less real.” The term metaverse has become popular. Today, people are spending more of their lives in virtual spaces.
The word metaverse comes from a science fiction book from the 1990s. But the metaverse has been around longer than that. Online communities have existed since the 1980s. We enter the metaverse through a screen. This could be through virtual reality(VR). It could also be through augmented reality(AR). Augmented reality covers computer-generated images on the real world. These experiences create a greater blending of our virtual and real lives. But these two worlds already cannot be separated and we don’t even need any headsets, such as VR glasses. Think about the Didi Taxi app. It uses location data to tell drivers where their cars are.
The metaverse is an expansion of the Internet. There are lots of Internet problems to solve already. Still, many people say it has real benefits. They say it can increase social networks and improve mental health. Hackl is a metaverse expert, and she’s African. She says, “You can encourage a lot more people to join and build social relations.” For those already spending part of their life in the metaverse, that building has begun.
Carrie Tatsu runs a business in the metaverse. But she wants her kids to spend time in the real world. “It’s so important for humans to be with humans in real life, ” she said, “I think as kids grow up in this space, it’s important for them to take part, go smell a flower here, walk on a trail, have a real conversation with a friend. Even though you can simulate that, the simulation is not the same. ”

C.Metaverse: a popular computer game. | D.Metaverse: businesses on the Internet. |
A Swiss radio station called Couleur 3 recently did an experiment on air, testing robot-created content and voicing.
During the 13-hour experiment, listeners heard the cloned voices of five human presenters. The station’s programming also included music created by AI. The program told listeners about the experiment every 20 minutes like this, “AI is taking your favorite radio by storm,” a voice said. “AI is here to surprise and shake you. And for that matter, this text was also written by a robot.”
The Swiss station’s director, Multone, said that Couleur 3 was able to do the experiment because it is already known for doing unusual things. He thought it as a lesson on how to live with AI. “I think if we become ostriches...we put our heads in the sand and say, ‘Multone, there’s a new technology! We’re all going to die!’ then yeah, we’re going to die because it (AI) is coming, whether we like it or not. We want to know it well so we can then put limits on it.”
Music that aired during the experiment was mostly created by AI methods. Besides, human-sounding robot voices provided false short news stories which were too imaginative to be believed. These included a story about one-month ban on spaceship flights over Geneva because of noise complaints. Another talked about the opening of the first underwater restaurant in Lake Zurich, while another told that ________.
There was a lot of discussion about whether to go on the experiment. He said he would stop the project if his team was not fully supportive. The station said it received hundreds of messages, with some supporting and others going against it. One person disliked the unfunny jokes. One considered the project a waste of time for a station that gets money from the government.
Multone said about 90 percent of listener reactions suggested the experiment was a good idea. But at the same time, many listeners pointed, “You can feel these are robots, and there are fewer surprises, less personality.”

8 . ① Going to the cinema is fun. However, in a time when technology has afforded us home video streaming services such as Netflixhy and Hulu, many people choose to stay at home to have fun. And they believe cinemas are going to have problems. Though those services might have a bad influence on the cinemas, I don’t believe the cinemas are going away anytime soon.
② As we all know, staying at home to watch films can save your money because the tickets for cinemas aren’t cheap. Besides, you can lie comfortably on a big sofa to watch films. And generally you can watch films for as long as you want. And you don’t need to worry that others will be angry when you laugh aloud.
③ But the cinema has the low lighting, the big screen, the surround sound etc. War movies especially benefit from being watched in cinemas. You can experience the war better and more closely. As well as war movies, action movies and superhero movies are also much better when seen on the big screen.
④Besides, you can enjoy the time with your friends and family when going to see a good movie. Therefore, you’d better not just watch a movie at home and then go to bed. you can hang out with your friends and share your latest news face to face based on going to see a movie together.
⑤Anyway, we are lucky enough to live in a time that benefits people who love to go out and those who love to stay at home. Netflix and other services will always be there for those who prefer to stay at home. But going to the cinema offers better experience, and it helps cinemas create more jobs. It’s a win-win. So why not see a cool movie at your local cinemas?
1. What influence do home video streaming services seem to bring?A.Cinemas will soon disappear. |

9 . On Dec. 9, 2021, three Chinese astronauts gave a science lecture 400 kilometers above Earth. Zhai Zhigang, Wang Yaping and Ye Guangfu, who are working abroad the Tiangong space station, showed millions of students their life there. They also did some fun science experiments. Let’s take a look at some of them.
Use it or lose it
The human body grows with the pull of Earth’s gravity. But in space, our bones and muscles don’t need to sustain our body’s weight. This will cause bone and muscle loss. NASA says that astronauts can lose up to 20 percent of their muscles after just a couple of weeks. That is dangerous because they will be too weak to work.
Astronauts have different ways to prevent this. During the lecture, Zhai introduced a special uniform Ye was wearing. It’s called a “penguin suit”. There are many elastic bands inside the suit. Wearing it, astronauts use their muscles to stretch the bands. This keeps their muscles strong.
▲ .
During another experiment, Wang made a water film. Then she added more water drops onto the film to make it a water ball. This can never happen on Earth. Why?
We need to first understand the surface tension of water. It is like a “skin” of water. The “skin” is there because water molecules are drawn to each other. Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in space, the “skin” stays strong and the water ball will not break.
Water in space acts differently from water on Earth in other ways. For example, water will not flow downward if you try to pour it into a cup. That’s why astronauts usually drink water through straws in sealed bags.
1. What can we learn about the lecture from space?A.It is a part of the astronauts’ daily work. |
B.It took place in the Tiangong space station. |
C.It is one of the astronauts’ ways to ask for help. |
D.It took place 500 kilometers above Earth. |
A.astronauts | B.muscles | C.bones | D.bodies |
A.Space water is valuable | B.Space water is different |
C.Space water is important | D.Space water is common |
A.To raise people’s interest in space exploration. |
B.To explain the importance of space experiments. |
C.To ask readers to do more science experiments. |
D.To introduce the space lecture given by Chinese astronauts. |
Hawaii is a truly beautiful place. Most people know Hawaii for its lovely beaches. However, Hawaii is also famous for hula, a special dance.
The Start
Hula started in Hawaii about 300 years ago. One hula teacher tells the story of how the dance started. “The hula started, as far as the story tells it, when a local girl Hiiaki and her good friend Hopoe went down to the beach, they noticed the waves and imitated. They used their hands like showing the waves.”
The Ban
Not everyone has always liked the hula. In 1820, some religious people from Western countries came to Hawaii. The visitors were very surprised because the dancers were not wearing many clothes. So the local government banned the dance. After that, most Hawaiians were not allowed to perform the hula in public for almost 60 years. But many dancers still performed it in secret. The dance was always there.
__________
At the moment, people of all ages want to study the old culture. As a result, more and more people are going to halaus. Halaus are special schools that teach hula in the traditional way. Kumano is a hula teacher. For him, the dance is a way to bring the best of old Hawaii culture to people today. Kumano says that the dance is not really about the body, but the mind. “For new dancers, the dancing means very little, because for Hawaiians today, many of them don’t speak the Hawaiian language. So, what I try to do is to bring to mind the real thing they see today.”

A.they didn’t like the story of how it started |
B.they hardly noticed the waves in the dance |
C.the dancers wore fewer clothes than usual |
D.there have been secrets in the dance since 1820 |
