1 . At a recycling center, two team members spend all day pulling items from a conveyor belt covered in garbage. One pulls out juice cartons and plastic bottles that can be reprocessed, while the other searches for pollutants in the stream of paper products. They are AI-powered robots that each look like a supercharged mechanical arm. Yes, even recycling has gotten involved in the AI revolution.
In theory, materials recovery facilities (MRFs) gather the wastes, sort them out, and then sell the materials to companies that can reuse them. In practice, the MRFs aren’t all that good. The issue is that it’s long been too hard for recycling plants to sort materials with the level of specificity needed to reuse them. The traditional recycling methods succeed in separating waste into broad categories of paper, glass, and metal. But finer layers of detail often go unnoticed, especially with plastic. It’s hard for recyclers to determine whether, say, a container is a milk container or a pesticide (杀虫剂) container.
AI stands to make a change, giving recycling plants a far more detailed view into packaging. The AI-powered recycling robots are “vision systems”: In the same way ChatGPT is trained, they ingest lots of photographs of thrown- away items in various states of damage. The robots are then able to identify even tiny differences in a product’s color, shape, texture, or logo. Recycling operators said that traditional systems tend to be 85 to 95 percent accurate, while robotics companies claim up to 99 percent accuracy.
That is not to say that the turn to AI has already fixed recycling. The high- tech systems won’t come cheap — an individual robot can cost as much as $300,000. Even if costs eventually decrease, recycling robots can’t change the fact that recycling, even at its best, is just not a particularly efficient way of dealing with single-use products. From a plastics- pollution standpoint, what’s better than a recyclable single-use cup is not using one at all.

3 . Technology and the Psychology of Second Language Learners and Users is a collection of studies that focuses on second language (L2) teaching and learning. This book, made up of 23parts, presents research on how technology affects the learning psychology (心理) of L2learners.
One of the main contributions of the book is that it is more than just a descriptive account of current research regarding technology and the psychological side of L2 learners. A key view is that technology does not necessarily lead to positive psychological effects. In fact, some learners may feel anxious or uncomfortable using technology for language learning, which can hinder their performance. What’s more, learner psychology still requires closer examination, as learners’ attitudes towards technology-assisted learning do not always match their actual practices.
Another important contribution of this book is that it presents the connection and interplay between language learners’ online identity and offline identity. As studies in the book have shown, positive online identities may support language learning and can potentially apply to offline situations. Also, individuals have different identities in the off line environment, which may influence how they experience online.
A third contribution of the book is that it provides various cases in detail to tell readers how to conduct research. Technology has created different online learning contexts for researchers to investigate, such as blogs and online social networks, to name a few. Thus, researchers are offered a lot of choices and have various studies to refer to when they do future research.
As illustrated above, this book provides both theoretical and practical value. It familiarizes researchers with the interplay of technology, psychology, and L2 learning, while also reminding teachers of the importance of integrating(结合) technology thoughtfully, considering individual learner differences. Adding instructions and steps on how to apply research findings to real teaching and learning contexts at the end of each part could further strengthen the book’s usefulness for language instructors.

4 . If talking near a busy road is tough, think how hard it is to raise a baby bird in that place. Anew experiment on growing birds shows traffic noise has a negative influence on their growth and leads to lifelong harm.
Researchers already knew too much noise can disturb breeding birds, making it more difficult for parents to communicate with and care for their nestlings. But it wasn't clear whether the noise itself could directly harm young birds.
Mariette, a behavioral ecologist at Deakin University, and her team set out to answer that question with zebra finches held in an aviary (鸟舍) on campus in Melbourne, Australia. For 5 nights they played eggs either road noise or zebra finch songs for several hours. The sounds were kept at a moderate volume of 65 decibel. Other eggs were left in silence. After the eggs hatched, the baby birds received one of two treatments — road noise or zebra finch songs — for another 9 nights. The nestlings heard the sounds in a separate room and then were returned to their nests.
Eggs that heard traffic noise hatched 19% less often than those that heard bird songs. As the baby birds developed, they also showed worrying development signs. Those exposed to noise grew slower, and had health problems. Their blood had fewer red blood cells, and their cells were under stress. When they became adults, they had half as many babies as the birds that heard songs when they were young. “I’ve never had such clear results in any experiments before,” Mariette says.
How exactly traffic noise harms the young birds remains a mystery. Auditory (听觉的) parts of the brain connect to areas important for development and the regulation of emotion and learning, so it’s likely that noise could disrupt healthy growth. Mariette says she would like to conduct other experiments to learn what aspects of noise are harmful. For example, it could be that hearing constant sound without any rhythm — unlike song — is somehow stressful.

5 . As a mother, I can’t imagine how heartbroken a mother would be if she is told that she can’t afford the treatment for her baby who suffers from cancer. And Cupcakes of Hope is a non-profit organization which raises funds to help families of children who are battling cancer.
Despite my poor health, I volunteered for this worthy cause. I’m not a good baker, but I am good at selling stuff, so I signed up to help turn all the beautiful, delicious cupcakes donated by others into money for these families in need. Our stand was set up in the Canal Walk Shopping Centre at 8 a. m. so that volunteers were ready to sell from 9 a. m. My shift started at 2 p. m. Before I got there, I expected to find a pretty empty table. I could not have been more mistaken!
Four big tables were full of beautiful cupcakes of every colour and flavour and there were3 shopping carts full of boxes of cupcakes which had not even been unpacked yet! The generosity and creativity of every single baker really were beyond my expectation.
The best moment of the day came when a sweet, blue-eyed toddler arrived at the stand. He was about 18 months old, happily sucking on a pacifier (安抚奶嘴) in his mom’s arms. I told his parents that all cupcakes were free gifts and all money raised would help families. His dad donated, and I picked out a Cookie Monster cupcake for the boy. As soon as I showed it to him he smiled from ear to ear, dropped his pacifier, and grabbed the cupcake. It made me feel happy and warm to see his bright eyes and joyful smile!
We kept turning cupcakes into cash until the last possible minute and still had enough cupcakes left over to donate to the needy! The time just flew by. I’m really grateful to have had the opportunity to do my small part for this very worthy cause.

8 . Beijing is a city of opposites, with one foot in the past and another in the present. Nowhere is this contrast more visible than in its architecture, where traditional and modern styles coexist. Here are three spots to enjoy the ancient architecture as well as spring flowers in Beijing.
Longevity Hill
Sitting at the back of Longevity Hill, the Flower Pavilion and Glass Tower are hidden spots in the Summer Palace where you can breathe in the colorful spring in quietude. The Flower Pavilion was constructed in 1754, and the Glass Tower in the pavilion was a gift from Emperor Qianlong to celebrate his mother’s 60th birthday.
The pavilion was destroyed by British and French soldiers in 1860 while the colorful tower survived. The original Flower Pavilion is in ruins but the flowers in the garden still blossom (开花) every spring.
The Imperial Garden
The Imperial Garden in the Forbidden City was only enjoyed by members of the royal (皇家的) family, but now its beauty can be appreciated by the public. The pink apricot flowers in front of the palaces have viewed the change of history.
Drum Tower and Bell Tower
Beijing’s Bell and Drum Towers lie on the northern end of the central line of the inner city. Looking at each other for hundreds of years, the two towers are surrounded by hutongs and trees.
The best place to enjoy the spring views of the old city is to find a coffee shop or a restaurant in the hutong, where you can see the spring flowers blossoming against the towers.

Ask yourself how you want to feel
Hobbies present an escape—they can help you get out of your head and calm down. It is necessary to ask yourself how you want an activity to make you feel. Mentally engaged? Relaxed? Socially connected? Recognize that you have different needs at different moments, and that’s OK.
Keep an open mind
Keeping an open mind and not ignoring potential hobbies is the key. Human beings are born to be curious and open, which is usually forgotten in this burned-out world.
Don’t spend a ton of time and money on a new hobby immediately. Ease in to figure out if it’s right for you, and you can always do more later. Try out a free online course or join a beginner’s group, for example, to get a feel of the hobby before committing heavily.
