But what exactly is an AI agent? As a computer scientist, I offer this definition: AI agents are technological tools that can learn a lot about a given environment, and then — with a few simple prompts from a human — work to solve problems or perform specific tasks in that environment.

Simple AI agents can be taught to reply to standard questions sent over email. More advanced ones can book airline and hotel tickets for transcontinental business trips. Take Google's Project Mariner as a typical example. Recently, Google demonstrated it to reporters. It's a browser extension for Chrome that can reason about the text and images on your screen. In the demonstration, the agent helped plan a meal by adding items to a shopping cart on a grocery chain's website, even finding substitutes when certain ingredients were not available. A person still needs to be involved to finalize the purchase, but the agent can be instructed to take all of the necessary steps up to that point.

Actually, many of today's AI agents tend to be utility (实用) based, meaning they give more consideration to how to achieve their goals by themselves. They weigh the risks and benefits of each possible approach before deciding how to proceed. They are also capable of considering goals that conflict with each other and deciding which one is more important to achieve. They go beyond goal-based agents by prioritizing their users' unique preferences.

However, a breach (违反) of an AI agent's system could cause private information about your life and finances to fall into the wrong hands. Are you OK taking these risks if it means that agents can save you some work? What happens when AI agents make a poor choice, or a choice that its user would disagree with? Currently, developers of AI agents are keeping humans in the loop, making sure people have an opportunity to check an agent's work before any final decisions are made.

When a squirting cucumber is ready to spread its seeds, it's like a little explosion. The whole process is super fast, lasting only about 0.03 seconds. The green fruit, which is about 1.6 inches long when ripe, shoots out a mixture of seeds and sticky liquid. It does this at a speed of around 45miles per hour, and the seeds can go as far as 33 feet away.

A long time ago, in the Roman Empire, a naturalist named Pliny the Elder first wrote about these squirting cucumbers. He warned that the seeds shooting out could be dangerous for the eyes. In the 19th century, studies started to explore its high-pressure seed spray, yet many details remained unclear. Now, Scientists used special cameras like high-speed video and time-lapse photography. They also did CT scans and made 3D models for in-depth study.

What they found is that before the seeds shoot out, a lot is happening inside the cucumber. As it fills up with fluid, some of that fluid goes into the stem. This makes the stem thicker and stiffer, and the fruit changes from hanging straight down to an angle of about 45 degrees. Shooting seeds from this angle helps them go farther. Also, when the stem detaches (分离) from the fruit, it gives the fruit a spin, which spreads the seeds out in a wider arc, increasing the chance of new plant growth.

"Scientists often look to model organisms (生物) — certain species that are well-studied. But there's also much to be learned by studying outliers that receive less attention, such as the squirting cucumber", Hay, a German scientist, said. "Many interesting traits are not found inmodel organisms," she noted. "This new study shows how we can learn from diversity."

At 14, Kobayashi came across a video of a historical Peking Opera, The Battle of Red Cliffs. Although he didn't understand the language, he was captivated by the costumes, makeup, and music. At 17, he found a website for the Shincyo Theater, a Peking Opera troupe (巡演) in Tokyo founded by Zhang Chunxiang, a Beijing-born artist, who had moved to Japan in the 1980s and founded the Shincyo Theater to promote Peking Opera in Japan.

Kobayashi emailed the theater, sharing with Zhang his passion for Peking Opera, and his desire to join the troupe. Zhang was impressed by his passion. At 18, Kobayashi moved to Tokyo to attend Chuo University, majoring in Chinese language and culture, while attending Zhang' s Peking Opera classes every Saturday.

Zhang teaches his students by explaining the movements of Peking Opera in simple Japanese. Kobayashi, who enjoys playing civil roles, listens to famous performances to learn the music and get a sense of the roles. He works with Zhang to improve his performance. Years of hard work paid off. In 2020, Kobayashi finally got the chance anddebuted in a small painted-face role in Wild Boar Forest, one of Shincyo Theater's productions, which got well-received.

After graduation, Kobayashi worked for a company in cosmetics, but he still studies Peking Opera in his free time and occasionally performs with Shincyo Theater. "Becoming a professional Peking Opera performer in Japan is difficult and might not be practical as a long-term career. In China, performers usually start training at four or five, whereas I began close to 20. Even so, I'd still like to pursue it professionally and give it my best shot," said Kobayashi.

The Chinese writing system, dates back to several thousand years ago, is one of the reasons for the (survive) of Chinese civilization.

Researchers generally agree that the oldest symbols that are recognizable as Chinese characters are those (find) on ancient oracle bones. These 3000-year-old symbols, known as jiaguwen, (carve) on turtle shells and used to tell fortunes and record events. They give people in modern era insight into how ancient Chinese people saw the world around them and into how they expressed their observations (creative). As people were divided geographically, this well-developed writing system evolved into (variety) dialects and characters. It was not until Emperor Qinshihuang united the seven major states into one unified country, the Chinese writing system began to develop in one direction. This united system has been great importance in connecting Chinese people and culture of the present with those of the past. Thanks to it, no matter when and where you are, people can read and appreciate ancient Chinese (classic).

With China continuously playing a greater role in international community, increasing number of foreign students are beginning to have a taste of Chinese characters and culture.

Decades later, my mother passed away from cancer, and I was8 for cleaning her home to prepare it to be sold. As I was9 the things in her room, I found a box stuffed full of paper. It contained every one of the10 I'd created as a kid, separated into folders based on how11 I was when I drew it. It was located near her bed table and had every sign of being12 on a regular basis. She really had saved and13 my terrible drawings all these years.

Hike with at least one other person. Not only is hiking more fun with a friend, it is also safer. If you decide to hike alone, make sure that you let someone know where you are going and when you plan to be back. This way, if you get lost or injured, someone will know where to look for you and when to send help.

Have plenty of water. Even if you are only going for a short hike, it is important to have lots of water on hand so that you avoid dehydration (脱水). Plan to bring one liter of water per person per hour of hiking. So make sure to drink your water frequently, even if you are not very thirsty.

Wear correct kinds of clothing. You should wear comfortable, closed-toed shoes and thick socks. Your clothing should be comfortable and easy to move around in. Clothing that is too loose might catch on rocks or branches.

If you have not exercised in a very long time, do not try to go on an 8-mile hike up a mountain on the hottest day of the year, Instead, you should start gradually. First, go for regular walks in your neighborhood. Next, you should try to find places to walk on steep hills or rocky soil.

A. Don't take a too long trip at a time.

B. Make sure that your body is prepared.

C. You can begin to dehydrate before you even realize it.

D. If you get injured, your friend will be able to go and get help.

E. But clothing that is too tight might become uncomfortable as you walk.

F. If you are going on a long hike, you might want to bring an extra pair of socks just in case.

G. With enough practice, you will be able to take longer hikes across more challenging landscapes.

"Most researches around body appreciation to date has focused on younger white Western women," said Louise Hanson, who led the study. "We wanted to expand the scope and include older women and other cultures as these groups have historically been not noticed."

A total of 1,186 women aged 18-80 were enlisted from six countries — four Western countries (Australia, Canada, the UK, and the US), as well as China and Nigeria. Participants were asked to complete questionnaires to understand more about their own sense of body appreciation and the pressures they experience around body image from family, peers and the media.

The results showed that all three groups had relatively stable body appreciation across ages. However, there were great cultural differences.

White Western women were found to experience much higher pressure from the media to meet thin or athletic body standards across their lifespan. This pressure did decrease with age, but even at its lowest, it was still higher than that for the other ethnic groups.

Black Nigerian women did not display a strong pressure towards a thin or athletic build and reported higher levels of body appreciation and far less media pressure regarding body image. However, they also reported higher levels of appearance pressure from peers, which reduced with age.

Meanwhile, Chinese women mostly continued to favor a thin body type across all ages. They reported the highest ongoing family and peer pressure around body image, but media-related pressure was less and decreased with age.

The researchers hope that their findings can encourage more cross-cultural studies to better understand the cultural dynamics that impact on body appreciation.
