2 . In various restaurants worldwide, there’s a new sight-child-sized robots. These robots can welcome guests, show them to their tables, deliver food and drinks, and even transport dirty dishes back to the kitchen. Some believe these robot waiters could be a solution to today’s worker shortages in the restaurant industry, with tens of thousands of them now in use.

But other people think that robots can’t replace human workers. Robot waiters can’t take orders, and they struggle with steps, limiting their abilities.

Despite these disadvantages, their use is growing. For example, in Madison Heights, Michigan, Li Zhai faced difficulty finding enough workers for his restaurant, Noodle Topia. To address this, he purchased robots from Pudu Robotics. These robots have been a success, with one leading diners to their seats, another delivering food, and a third transporting dirty dishes.

Zhai found that using these robots reduced his need for employees. Three robots now do the work of what used to require five or six people. In terms of cost, a robot costs around $15 000, while a human can cost $5,000 to $6,000 per month. These robots also have a surprising benefit-they free up human servers to spend more time with customers, resulting in increased tips, Additionally, diners often share videos of the robots on social media, attracting more visitors to the restaurant.

However, not all restaurants have had the same success. For instance, Chili’s (奇利斯餐厅)introduced robot servers in 2020, expanding the test to 61U.S. restaurants before suddenly stopping the program. The robots were criticized (批评) for their slow movement and getting in the way of human servers. A survey showed that 58% of guests believed the robots didn’t improve their overall dining experience.

4 . Wildlife conservation is the practice of protecting plant and animal species and their habitats. As part of the world’s ecosystems, wildlife provides balance and stability to nature’s processes. Wildlife conservation is aimed to ensure the survival of these species and educate people on living sustainably with other species.

The number of people has grown to more than eight billion today, and it continues to rapidly grow. The economic growth endangers the habitats and existence of various types of wildlife around the world, particularly animals and plants that may be displaced for land development, or used for food or other human purposes. This threat is at top of the list and means natural resources are being consumed faster than ever by the billions of people on the planet. The introduction of invasive species from other parts of the world is another threat to wildlife. Other threats include climate change, pollution, fishing and hunting.

International organizations like the World Wildlife Fund, Conservation International, Wildlife Conservation Society and the United Nations work to support global animal and habitat conservation on many different fronts. They work with the government to establish and protect public lands, like national parks and wildlife protection areas. They help write legislation(法规), such as the Endangered Species Act(ESA)of 1973 in the United States, to protect various species. They work with law enforcement to charge those with wildlife crimes. They also promote biodiversity to support the growing human population while preserving existing species and habitats.

National Geographic Explorers, like conservation biologists Camille Coudrat and Titus Adhola, are working to slow the extinction of global species and protect global biodiversity and habitats. Environmental filmmakers and photographers, like Thomas P. Peschak, are essential to conservation efforts as well, documenting and bringing attention to endangered wildlife all over the world.

5 . German Chancellor Olaf Scholz has dismissed concerns that growing Chinese competition is a threat to the local automotive industry, while welcoming Chinese carmakers to Europe’s largest auto show, IAA Mobility 2023, in Munich.

The six-day event officially opened on Tuesday. Scholz said increased competition from China was good for the German auto industry. “Fair competition stimulates business. It is in the interest of consumers,” he said, “as Chinese electric vehicle companies show eased several new fully electric models, out shining some German automotive giants.” Competition should stimulate us on, not scare us.

“The countries that have achieved great prosperity in the course of globalization, the workers there, have no less right and no less claim to the opportunities of modernity than we do,” Scholz said of China.

“In the 1980s, it was said (that) Japanese cars would overrun the market. Twenty years later, it was cars made in South Korea and now supposedly Chinese electric cars,” Scholz, who wore a black eye patch due to an injury from a jogging accident on Saturday, said.

The German chancellor also expressed confidence in his country’s strengths. “There is no question about the international competitiveness of Germany as a car country,” he said, adding that “Germany is still the linchpin of the auto industry and will remain so.”

Jun Jin, an auto industry expert, said the international market provides great opportunities for Chinese EV (电动汽车) makers, given their strength in technology and costs. “But this does not simply mean repeating their China success story; they need to succeed by adopting local practices,” Jun told China Daily.

Chinese companies, he said, still count on exports and have a long way to go before manufacturing vehicles overseas, arranging global supply chains and improving services for local customers.

6 . You may have heard video game characters deliver lines like “Shatter (击碎) the darkness with thunder!” But it’s refreshing to hear it in an unexpected place — the classroom. Xia Zhendong is a physics teacher working at a senior high school in south China. Now in his 30s, Xia has won the hearts of millions of online viewers with his classroom experiments.

In one video, Xia pointed a self-made “thunderbolt wand (魔杖)” toward a hanging light tube in his classroom and said, “Shatter the darkness with thunder.” Suddenly, an electric arc (弧线) emerged from the tip of the wand, illuminating the tube. After the cheers from his students, he went on to explain the science behind it—static electricity (静电) and point discharge (尖端放电).

“The idea came when I enjoyed playing a popular game on my smart phone,” he said. In his spare time, he likes to try out what students are interested in to get closer to them. Apart from the “thunderbolt wand”, Xia has done many other creative experiments. Once, he lit steel wool with a battery to show the heating effect of electric current. Another time, he used a “laser weapon” to pop balloons while explaining the principles of lasers.

For Xia, physics is supposed to be fun. So, when he saw his students struggle with physics, he decided to make a change. “Circuit diagrams (电路图) are abstract, and I want them to actually see the electricity through lightning to realize that knowledge is not just on paper. You can see it and even touch it,” Xia said. Now, Xia has also started free live classes online. “I hope that through online classes, more students can also have access to fun physics lessons. And their parents can also join in. I hope that physics could make them feel happier,” Xia said.

10 . Pushpa hates tears but when she tells of incidents from her childhood, which she spent battling poverty, she can’t help feeling overwhelmed. “We used to be able to afford only one meal every day,” she says. But as challenging as those early years were, they would lead to her remarkable life as a scribe (抄写员) for people with special needs.

Pushpa remembers enjoying a blessedly normal childhood, peppered with “toys, dinners out and movies at the theatre”, until around grade 4. But life as she knew it disappeared when an accident left her father disabled.

“My mother, who wasn’t well-educated, had to work for ＄500 per month.” But what hit her hardest was her struggle to continue her education. The memory of her grade 7 teacher refusing to allow her to attend classes over unpaid school fees still hurts.

One day in 2007, while travelling with two visually impaired (有缺陷的) college students by bus, she heard them talk about how difficult it was for them to continue their education. “I remembered my own struggle to finish my studies so I seized the opportunity to help them.”

“I was a little nervous at first because I had passed my grade 10 examination only with a third class,” she smiles. “Since then, I’ve written exams for students who have low IQ, or are blind or visually impaired, or have met with an accident.”

It is, by no means, an easy task. “I read out the questions slowly and, sometimes, several times, and wait for the student to tell me the answer. I have seen scribes getting irritated (愤怒的) at students and that should not happen.” she explains.

Over the last 16 years, the young girl who once survived on handouts has come a long way. Connecting with examinees by word of mouth, till date, Pushpa has written 1,086 exams for special-needs test-takers and won the Nari Shakti Puraskar in 2018 for her efforts. “You should be prepared to help the student for those few hours, without expecting anything in return.” Pushpa adds.
