1 . “Beijing’s Forbidden City can be at risk of being flooded, but it’s not because modern technologies and repairs have deteriorated the drainage (排水) system,” Beijing News Radio reported.

The report is in response to a popular online view: The Forbidden City, the royal palace of Ming and Qing dynasties also known as the Palace Museum, has never been flooded throughout its history of more than 600 years.

Earlier, a video showed ankle-deep water near the Forbidden City’s Cining Palace, where the royal women used to live. Some netizens have questioned whether modern drainage repair works have made the system much weaker.

Di Yajing, an official in control of affairs relating to the site, told Beijing News Radio that the Forbidden City has a complex (复杂的) drainage system. “Rain coming down from roofs was guided to the basement and then to the drains,” she said, adding that rainwater would flow from the central of the palace to both sides, and from north to south, due to differences in heights.

“The drains were cleared once a year in springtime in ancient times and nowadays they are cleared three times a year except in winter,” the report said. “Although the number of clearing increased every year, it’s not modern technology that worsened the ability of the drainage system,” the report said. During the clearing process, workers found lots of modern objects such as plastic bottles and bags, even towels and clothing, and these things resulted in the blocking of the drainage system.

In addition, there are plenty of records that have recorded occasions in which the palace was flooded and some roofs or walls were damaged by floodwaters, according to the report. For example, a rain in 1885 led to floodwaters of about 1 meter deep. Every time people would have to find out the place of blockage, clear it and then the drainage system would work well right away.

2 . The first wave of concerns over artificial intelligence(AI)in 2023 appeared soon after New Year’s Day when classrooms reopened and schools from Seattle to Paris started blocking ChatGPT, a powerful software based on AI large language models, because teenagers were using it to do their homework.

The AI large language models behind such products as ChatGPT work by repeatedly guessing the next word in a sentence after having “learned” the rules from a huge amount of/human-written works. Although they often get facts wrong, their answers appear so natural that Keven, their inventors begin to worry about their possible use for spreading false information.

People became more worried when various AI products started to create not just texts but novel images, music and human voices, which threatened the livelihoods of anyone who writes, draws or sings for a living. It led to strikes by Hollywood writers and actors and legal challenges from artists and bestselling authors. Some of the most respected scientists even warned that the technology’s unchecked progress was possibly threatening human existence. “In the longer term, they might manage our attention,” pioneering AI scientist Fei Fei Lisaid. “They would tell us which video to watch, which book to read or whose communication to respond as AI technology’s abilities improve rapidly. They could be a very good assistant, but also with really big risks.”

Li hoped that 2023 is going to be a year for people to think about what Al is, how to use it and what the effects are — all the good, the bad and the ugly.

“It’s easy to forget that they are not the first wave of AI products. Computer vision techniques developed by Li and other scientists have helped sort through a huge database of photos to recognize objects and individual faces and guide self-driving cars. Speech recognition advances have made voice assistants like Siri and Alexa a normal thing in many people’s lives,” said Tom Gruber, co-founder of Siri Inc.

3 . Janet, now 37, was playing with her new pet dog, Stitch, who jumped up, grabbed her sleeve, and tore several holes in her sweater with its sharp teeth. Instead of throwing the sweater away, Janet decided to repair it.

She turned to “visible repairing,” an idea of repairing clothes that leaves an obvious fix. She added bright flowers and other small designs to damaged clothes. “Every time you do a repair, it’s like having bought a new piece of clothes,” says Janet.

Actually, repairing is a great opportunity to realize the urgent (迫切的) need to reduce waste. Sadly, we have become used to replacing things instead of repairing them — and the rubbish is piling up. Worldwide, we throw away 92 million tons of cloth every year. Electronic waste is another growing problem: About 50 million tons of it is created each year around the world.

The good news is that fixing things can help deal with the waste problem. There are some solutions. Due to information online, the popular how-to site iFixit.com , a database (数据库) with nearly 100,000 repair brochures for everything from electronics to clothing, has promoted more than 100 million repairs. In addition, since the first Repair Café opened in2009 in Amsterdam, more than 2,700 cafés have been set up to offer in-person fix-it help in various countries. Organizers set up events, and volunteers with repair knowledge bring their tools. They will try to fix whatever people bring in, for free, and teach visitors how to do repairs themselves.

Fixing things is part of a larger change toward a circular economy —the idea that instead of throwing away things once they are broken or out of date, we reuse or repair them, keeping them out of the landfill (垃圾填埋场) for as long as possible. According to a 2023 report from Circle Economy, a Netherlands-based NGO, if the world changed to a circular economy, we could lower the amount of waste by a third.

Students’ Time Spent on Physical Exercise Weekly

Nowadays, many students are aware of the significance of physical exercise, although the time they spend on it varies.

5 . Many Silicon Valley parents are becoming more concerned about preventing their children from using screens. Some parents think that even a little screen time can be extremely addictive, so it is better if their children avoid using or seeing these devices completely. However, it is difficult for working adults in the 21st century to give up using a phone at home. So, it’s simpler to employ someone to do this.

“Silicon Valley nanny (保姆)”, who takes children back to a time without screens every day is widely needed. From Cupertino to San Francisco, it’s widely agreed that screen time is harmful to youngsters. Therefore, parents are requesting nannies to keep phones, tablets and computers in a hidden place. Others even offer no-phone agreements.

Research shows that spending too much time on technology can harm young minds. For example, teenagers who use social media frequently are more likely to feel depressed and anxious. Insomnia (失眠) rates have also increased amongst this age group, and an increasing number of children display the signs that they can’t focus attention. These seemingly minor (轻微的) problems could become significant challenges for future generations.

“Many parents come back home and focus on their smartphones, ignoring whatever their children are trying to say,” said Shannon Zimmerman, who works as a nanny in San Jose for families that forbid screen time. “As a nanny, I also call on more parents to spend more time with their kids.”

8 . We’re frequently told that our attention problem-being easily distracted-result from modern technology. If we truly want to focus, according to the popular belief, we need to turn off all our digital devices and quit social media.

Here’s my opinion about that idea. This era(时代)is no different than any other-there has always been a “crisis of attention”. Think about life long ago: people in ancient India or Europe didn’t have smartphones and social media, but they were faced with the same problem.

A crisis of attention can happen anytime you don’t allow yourself a break-when you don’t allow your mind to daydream, which may inspire your creativity. We are always engaged in something. With these digital tools at our fingertips, we have constant access to all these forms of communication, content, and interaction, and we don’t let our thoughts wander(漫游)freely. When was the last time you stood in line at a store and just…looked around? Thought about whatever came to your mind? Or did you pull out your phone, check your texts, read your email during that time?

We all do it. We catch ourselves all the time going from one type of mental engagement to the next. Like surfing online (clicking from link to link), we go from one task to the next and the next. We are “all task and no downtime”. Even something you might think of as relaxing is more engagement. Checking your phone messages may seem “fun”, but it’s just another task for your attention. Your attention is focused on task after task after task, without a moment for the mind to wander freely.

It’s not always realistic to unplug. We can’t just turn off our phones and pause our email. We can’t create a distraction-free world. The problem is not the existence(存在)of modern technology; rather, it’s how we’re using it.
