【推荐1】A special copyright (版权) case has recently drawn attention because it is about artificial intelligence (AI). A court (法庭) in Shenzhen ruled that a news report written by Tencent’s AI enjoys copyright protection. A website broke the law because it used the article without permission (允许). This is the first case in China that has provided copyright protection to work done by AI. But what does it show us? Will AI take the place of creative workers in the future?

Probably not. AI is not yet able to write creative stories. The news report mentioned above is mainly about data. Since AI is good at dealing with data, it is often used to write financial ( 金融的) reports.

Some newspapers also use AI to report on stories about natural disasters (灾害), which mainly require basic facts such as “where” and “when”. As Forbes wrote, instead of losing their jobs, reporters can make their work more efficient (高效的) by using AI so that they can put more energy on storytelling and less on numbers.

AI is actually being helpful in many creative fields. For example, Wayne McGregor, a British choreographer (编舞), is famous for using AI to create new dances. For him, AI is a powerful tool that can help choreographers break out of common movement.

“It’s time to stop worrying about if AI can be creative,” according to Forbes. Instead, we should pay close attention to how humans and AI can work together in ways that we have never dreamed of before.

② A team at RMIT University in Melbourne, Australia, found a way to put special nanostructuresinto clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains (污渍) that don’t belong on your clothes.
③ The nanostructures don’t break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothing in a solution made of silver and copper (铜) nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new.
④ So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment.
⑤ According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done.
⑥ “There’s more work to do before we can start throwing out our washing machines,” said Dr Rajesh Ramanathan, “but this is a strong foundation (基础).”
⑦ So what’s the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat the clothing with the solution while clothes are being made.

【推荐3】Weiqi, as an old board game, was invented in China more than 2500 years ago. And the game is played until today.

The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the game board. As we know, the board surface has 361 cross points. The stones are placed on them.

Weiqi is also called go in the world. Learning it can not only improve people’s logical (逻辑的) thinking ability, but also it can develop their calm character. That’s why it is more and more popular with modern people.

In the Sui and Tang Dynasties, Weiqi traveled to Japan, and then to Europe in the 19th century. Now it has grown into an important international competition event. So far, players from China, Japan and South Korea have the highest level of Weiqi.

On February 19, the Chinese-English Dictionary of Weiqi Terms (术语) came out in Beijing. It’s the first professional dictionary about Weiqi in China. As a symbol of Chinese culture, Weiqi has its special language. It also has its own way of thinking and the method of communicating. The dictionary will serve as a necessary tool and bridge for spreading Weiqi culture.

【推荐1】Artificial intelligence (AI) is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make computers “smart”. John McCarthy, a scientist, came up with the name “artificial intelligence” in 1955. Many things such as learning and problem solving can be done by computers, though not in the same way as we do.

Some people have welcomed AI because it makes things possible. In some industries, AI is already doing the work that people used to do, such as assembling(装配) cars, digging the coal and lifting goods. Even more, AI will have a big influence on our daily life. The AI self-driving car will take us to our destinations (目的地). An AI tutor will help us with homework at home. The future of AI looks quite bright.

However, there are still some risks. Self-driving cars and trucks controlled by AI will take away drivers’ jobs in the future. What’s more, according to an expert, “Every AI advance by good people is an advance for the bad people, too.” The biggest worry is that bad people could use AI for evil purpose. For example, they could use AI to create websites that steal people’s personal information. Or they could use AI programs to hack software and break into computer systems. Although AI has its risks, it is clear that AI is here. It has been used in many ways and it is changing how people live and work. That makes AI important to watch, not to fear.

【推荐2】Today, people who need heart transplants (移植) must wait and hope to receive a donation. Even if they survive the wait, they might experience organ rejection (器官排异)and die. But this problem could be solved soon.

On April 15, 2019, scientists from Israel’s Tel Aviv University announced that they had created a human heart using 3D printing. “This is the first time anyone anywhere has successfully engineered and printed an all heart,” scientist Tal Dvir told Ha’aretz.

The heart has cells, blood vessels(血管), ventricles(心室) and chambers(心房), just like a real heart. But scientists still have more to make certain before they can start using the hearts. For one thing, the new experimental organ(器官) is tiny about half the size of your thumb(拇指). It also can’t pump(抽吸) blood yet. It’s like a tiny airplane that has all of the right parts, but can’t fly.

Don’t laugh, though! This is still a major achievement. The World Health Organization (WHO) says more people die each year from heart diseases than any other cause of death. Dvir and his team used a complex process, turning human fat tissue(脂肪组织) into human heart tissue with stem cells(干细胞) technology. The tissue was then turned into “bio-ink” for the 3D printer.

Perfectly, each printed heart would use tissue taken from the person who needs it. This way, the patients’ bodies will be less likely to refuse the organ, making transplants much safer. In theory，the skill could be used to produce a new heart in just one day.

The team’s next step is to develop the technology further and use it to print other human organs.

“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these programs will be managed regularly,” Dvir said.

1. What do we know about the 3D printed heart?

A．It doesn’t have blood vessels.	B．It is the same size as a real heart.

B．Because it offers some hope to people with heart diseases.

C．Because it was produced through a complex process.

D．Because it proved that printing human organs is impossible.

3. What was used to make the printed heart?

A．Fat tissue.

B．Heart tissue.

C．Stem cells.

D．Heart cells.

【推荐3】One after another, telecommunications giants such as Huawei, Samsung and Qualcomm have announced their latest fifth generation（5G）products with Huawei’s Mate X and Samsung’s Galaxy Fold attracting most eyeballs.

The telecom giants have also announced that 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters have described it as a “much faster” technology than 4G without mentioning any of its other advantages. As a result, the common public idea about 5G is that they could “download a huge movie within one second”. Beyond that, most people know nothing about 5G.

Actually, 5G technology has many more advantages than 4G apart from speed. According to 3GPP, an international standardization organization, 5G technology can be used for at least three purposes-for connecting everything, reliability（可靠性）of connections, and removing delays.

“Connecting everything” is a proper slogan for 5G technology, without which the Internet of Things would be impossible, For example, self-driving cars contain several kinds of sensors, such as radar, computer vision, and GPS to identify driving routes, obstacles and road signs. 5G technology will link all the elements of a transportation system, such as traffic lights, CCTV cameras and, of course, cars to build up perfect coordination so they can avoid obstacles and move on driving routes, which will help strengthen self-driving technology.

Reliability of connections is another key characteristic of 5G technology, whose use can be spread to other fields where high safety standards are required. For example, in certain surgeries（外科手术）, doctors put nano-robots inside a patient’s body and have to keep constant control over the robots to ensure they work well and do not cause any harm to the patient. This is an area where 5G technology can be of great help, as it can build up reliable and continuous connections between the monitor and the nano-robots.

And removing delays might come in handy especially in online games. Even long after 4G technology was introduced, players continued to complain about losing games because of low speed. This problem can be solved with 5G technology, because it will ensure continuous high speed.

And for those people who think that 5G costs will be very high, they need not worry. The cost problem can be solved in two ways.

First, factories can produce more micro base stations, which not only occupy less space but also cost less. And second, many more terminals（终端）can use a 5G base station compared with a 4G base station. The more terminals using a 5G base station, the lower cost each of them have to pay. Therefore, 5G technology won’t be as costly as you thought.

1. How does 5G technology help improve self-driving technology?

A．It clears me obstacles for the cars.

B．It connects every part of a transport system.

C．It makes the self-driving car run much faster.

D．It controls the traffic lights and CCTV cameras.

2. What is the use of 5G technology in certain surgeries?

A．It ensures high speed for the robots.

B．It helps the robots do the surgeries without doctors.

C．It enables doctors to put nano-robots inside a patient’s body.

D．It makes the connection between the monitor and the robots better.

3. Factories can produce more micro base stations so that _________.

A．people can pay less for 5G	B．5G can be compared with 4G
C．the “5G epoch” can come sooner	D．more terminals can use a base station

4. What’s the best title for the passage?

A．The “5G Epoch” is Coming	B．5G-Less Cost with Higher Speed
C．The Latest Fifth Generation Products	D．5G Technology is more than about High Speed

【推荐1】Recently, Lei Jun, the founder(创始人) of China’s tech company Xiaomi, called for more e-waste recycling plans in China. “China should set up different recycling ways to make full use of the unwanted electronics such as smartphones and computers to reduce the country’s carbon emission(碳排放), ” Lei told CCTV News.

According to the 2020 UN Global E-waste Monitor, the world’s e-waste will reach 74.7 million tons by 2030. That’s almost a doubling of e-waste in just 16 years. This makes e-waste the world’s fastest-growing household waste. The report also found that only 17.4 percent of the world’s e-waste was collected and recycled in 2019. This means that gold, silver, copper(铜) and other high-value materials were mostly burned or thrown a way instead of being reused. It’s a waste of 57 billion dollars, or 360 billion yuan, E-waste can also harm the environment and people’s health. For example, one mobile phone battery can pollute 600, 000 liters of water.

China is now the world’s largest producer of e-waste, followed by the US, India and Japan, according to the UN report. Tech companies are looking for different ways to solve the problem. For example, US company Apple built a robot called Daisy to take iPhones apart. With Daisy, valuable materials can be pulled out more easily and then they can be reused. Samsung plans to use recycled materials in all of its new products by the year 2025. Xiaomi is also setting up e-waste recycling platforms so that people can donate or sell their old electronics more easily.

1. What is Lei Jun’s suggestion according to the first paragraph?

A．To reduce the use of e-products.

B．To reuse the old computers.

C．To recycle more e-waste.

2. In which year did the amount of e-waste reach about 37.3 million tons?

A．2014.

B．2019.

C．2021.

3. Throwing away e-waste can cause bad influences EXCEPT ________.

A．waste of valuable materials

B．no more electronics to use

C．harm to health and environment

4. Why does the writer mention Apple’s Daisy, Samsung and Xiaomi?

A．To explain why we should deal with e-waste.

B．To advise our country to work with others.

C．To give examples of reusing e-waste.

5. Where can we probably read this passage?

A．A travel magazine.

B．A comic book.

【推荐2】“Hello, everyone! Welcome to Tiangong Class.” With this greeting, a special class began on Tiangong space station about 400 kilometers above Earth on Dec 9.

Lasting for about an hour, the space class was broadcast live to millions of students. Three astronauts from the Shenzhou XIII crew hosted the class, demonstrating how they live and work on the space station and guiding some interesting experiments that can only be done in space.

Because of technological development, the quality of space to ground interaction and communication is much improved. The space class eight years ago sometimes faced the challenges of the video freezing and an unclear picture, but this year’s class is different. With the help of China’s Tianlian relay satellites, the transmission speed has been highly increased and the whole live broadcast has run smoothly.

This year’s space class discussed more rules of science. Eight years ago, Wang showed students the rules of physics and focused on the interesting phenomenon of weightlessness in space. But this year, biology was added. The astronauts compared the growth and shape of cell(细胞) in artificial gravity(人造重力) and zero gravity, so as to study their changing rules.

Though these space classes showed different topics, the aim behind the classes has never changed. The space classes aim to spread knowledge about manned spaceflights and build dream for science among young people.
