1 . On April 18—the International Day for Monuments and Sites, China Daily’s digital employee Yuanxi and Dunhuang Mogao Grottoes’ official virtual cartoon figure Jiayao together introduced an interactive digital platform that hosts a virtual copy of the Mogao Grottoes’ Library Cave(藏经洞) to the world.

The platform was developed jointly by the Dunhuang Academy and the Chinese tech firm Tencent. It uses gaming technologies to show the historical scenes of the Library Cave in the digital world.

The Library Cave in Mogao Grottoes was discovered in 1900, with more than 60,000 cultural relics dating from the 4th century to the 11th century unearthed. It was one of the most important archaeological discoveries in the 20th century.

On the platform, visitors can role-play and “time travel” to ancient dynasties and talk with eight historical figures. The public can enter the platform through the Digital Dunhuang website and its WeChat mini program.

In the digital age, the model of “culture+technology” has been introduced to promote the development of Chinese culture. The digitalization rate of China’s precious cultural relics is now over 70 percent, according to the 2022 China Digital Collection Industry Research Report released by iResearch.

Institutions such as the Palace Museum have also started online digital services of their own. Artificial intelligence (AI) technology allows the public to view the interior of the buildings through the Palace Museum’s WeChat mini program.

The Ministry of Culture and Tourism has also encouraged the development and transformation of cultural intellectual property(知识产权) by digital means. China Central Television has created a series of digital collections with different Dunhuang themes, such as the Dunhuang divine deer(神鹿) Youyou. It was created based on the image of the nine-colored deer from Dunhuang murals(壁画). The public can see the divine deer on CCTV’s own digital platform.

Digital collections cater to the consumption habits of young people, who grow up in the information age. They not only protect the intellectual property of the collections but also bring the public closer to China’s “excellent traditional culture”, noted Dunhuang Art Institute.

Su Bomin, director of the Dunhuang Academy, told Xinhua that more efforts will be made to explore new forms for showing cultural relics and offer the public greater cultural experiences to develop Dunhuang culture.

5 . Scientists once thought bigger brains made smarter animals. But birds fly in the face of that logic: with a brain smaller than a walnut, they can develop complicated tools and remember where they hid food. Now research published in Current Biology suggests birds can pull this off because their brain neurons (神经元) use less energy than those of mammals (哺乳动物), letting their bodies support a higher proportion of these cells.

A 2016 study showed that bird brains are denser (密度大的) than those of many other animals. For example, a parrot’s 20-gram brain holds as many neurons as a squirrel monkey’s 30-gram brain.

In the new research, when compared against the neuronal energy budget of mice, humans and other mammals, a pigeon neuron used three times less energy than the average animal’s neuron―a “really surprising” result, says the bird scientist Kaya von Eugen of Ruhr University Bochum in Germany. Although bird neurons are likely smaller than a typical mammal’s, she adds, the difference in energy use “is so big that this cannot be the only explanation. “Perhaps, she suggests, bird brains are organized so that neurons can more easily exchange signals, or maybe birds’ warmer body temperatures let neurons function faster. The author guesses that complex mental needs such as song and flight could have pushed the evolution of more efficient brain cells.

The finding is “pretty remarkable,” says Vanderbilt University scientist Suzana Herculano-Houzel, who worked on the 2016 study but was not involved in the new research. Based on the density difference between mammal and bird brains, she says, the energy difference is “exactly the math you’d expect.” Birds may have evolved this feature simply to work with their limited energy supply, rather than to consider advanced processing needs.

A．Stop flying whenever they want.	B．Have brains smaller than walnuts.

2. How is the new research conducted?

D．By studying diagrams and numbers.

3. What does Kaya von Eugen find surprising?

A．Bird brains exchange signals more easily.

B．Neurons function faster in birds’ warm body.

C．Birds have more efficient brain cells.

D．Pigeons use much less energy than average.

4. What can be inferred from the last paragraph?

A．Birds eat less to become smarter.

B．Bird brains are becoming bigger than before.

C．Birds become smarter due to the insufficient food supply.

D．Birds become smarter to consider how to process food.

6 . Astronauts drink their own pee (尿)—after it's been cleaned.     1     Many experts, though, argue that recycling pee and other waste is an excellent and safe solution when there isn't enough fresh water to go around.

    2     All of the water that astronauts use to drink, brush their teeth, or make coffee comes out of one limited container that has to be resupplied—from Earth. To help conserve water, the waste from sinks, toilets, and even the pee from lab animals on board flows into a recycling system. First, the water goes through a series of filters(过滤器) to get rid of large particles(微粒) and impurities. Then, chemical reactions remove poisonous chemicals and kill any bacteria or viruses.     3    

Chris Hadfield, who lived on the space station for five months, says, "Before you feel uncomfortable with the thought of drinking your leftover wash water and your leftover pee, keep in mind that the water that we end up with is purer than most of the water that you drink on a daily basis at home."

Astronauts, however, tend to be more adventurous than the average person. On Earth, cities in very dry parts of the world have attempted to introduce wastewater purification systems.     4     Citizens recoiled(退缩) in disgust. Despite scientific evidence that the water is clean, many people just can't get over the fact that it once flowed through a toilet. In the 1990s, activists in San Diego and Los Angeles campaigned against "toilet to tap" water.     5     In a survey of 2,000 Americans, 26 percent agreed with the statement: "It is impossible for recycled water to be treated to a high enough quality that I would want to use it."

A．And you wouldn't be alone.

B．And the disapproval remained strong.

C．what comes out is clean enough to drink.

D．On the International Space Station, water is a precious resource.

E．Lots of people feel sick at the thought of drinking recycled wastewater.

F．Though some of these programs have succeeded, others failed miserably.

G．Would you pick up a glass of water that's been through a wastewater cleaning system?
