1 . By drawing patterns on the surface of a cup of tea, chabaixi (茶百戏), an ancient Chinese tea trick displayed in a recent TV drama, has gone viral for its apparent similarity with modern coffee art. However, ten years ago, this distinctive technique was close to disappearing. Zhang Zhifeng, a practician of chabaixi, found scenes of chabaixi in the drama aroused great interest among ordinary people.

Chabaixi can create endless patterns such as bamboos and mountains or even calligraphy. There are over a dozen steps, from grinding (碾碎) tea for fine powder, to pouring boiled water, stirring the mixture for thick froth (泡沫), and finally drawing the patterns. It is different from making coffee because people use clear water as the object to put into the cup instead of milk. But when the water touches the surface of whipped (搅打起泡的) tea, it turns into a white color and disappears in 20 minutes. The process before the drawing is known as the tea—making technique, diancha. The quality of diancha is crucial to whether patterns can be successfully produced later.

“Chabaixi is one of the countless forms of tea-making techniques in China. The importance of chabaixi is not only that this technique is unique in the world, but also it gives us a window into people’s lifestyle in the Song Dynasty, a period of time when leisure activities in some ways are similar to what we have now,” Zhang said.

Before chabaixi was discovered by TV audiences, the technique was listed as part of China’s Intangible Cultural Heritage in 2017, after it was recovered by Zhang Zhifeng. He started researching the origins of chabaixi in the 1980s and brought the technique back in 2009 after decades of trials and practice.

“To let this technique fade would be a shame. It must be passed on to the next generations so they can understand its history,” Zhang said.

2 . As a child, I never considered myself an athlete at all as I was very uncoordinated(不协调的). However, I did love to run because I felt as if I was flying but this all changed two years ago when I suffered a knee injury. I was bedridden for two weeks and I had a difficult time moving even short distances. I literally cried myself on my way to the car for a few days.

When therapy wasn’t working well for me, I signed up for a hot yoga class for girls, Bikram Yoga to be exact. Starting a yoga practice was truly a godsend because it helped me gain strength in my knees but, most importantly, yoga helped me attain a more peaceful state of mind, body and spirit.

Since each class was heated to 105°F, every time I stepped foot in the yoga studio, I’d feel a surge(涌起) of negative thoughts come upon me like a big ocean wave. Some of these thoughts were, in the beginning of my practice, so strong that I walked out of the class several times. However, as the months passed by, I noticed that when I didn’t get swayed away by my negative thoughts, I could stay in the hot room for longer.

After 3 – 4 months of practicing hot yoga, my arms and legs were beginning to get definition. I also woke up with so much more energy than I had before starting my yoga practice and I gradually started shedding the pounds from my body. Yoga literally made me feel as if I’d taken a shot of energy drink and just gave me that burst that helped my knees heal and made my overall health better.

As I saw some of my classmates do poses that looked appealing to me, I started to think maybe I could do them too. Therefore, yoga helped show me that I have no real limitations physically unless I set those limitations myself through eating junk and thinking in negative limiting terms.

Also, practicing yoga in front of a mirror helped me connect with myself and practicing with a group of people really helped me to feel a greater sense of connection with humanity whereas before I didn’t. Overall, this yoga practice has helped me to see I’m part of a bigger picture in life!

5 . Seagrass meadows(海草床)are wonder plants growing beneath the sea. They feed and shelter sea life and are masterful at storing carbon.

Seagrass has usually been detected by Earth-orbiting satellites that identify darker patches in the blue water. In this study, tiger sharks were selected as research tools due to their highly consistent associations with seagrass ecosystems. They spend 70% of their time in seagrass meadows. The team equipped eight tiger sharks with satellite tags and used a 360-degree camera on them for the first time ever.

The data researchers collected was astonishing. The world’s largest seagrass ecosystem, measuring at least 66,900 square kilometers, has been discovered. This reflects a 41% increase from previous estimates of global seagrass. Seagrass can capture(捕获)huge quantities of carbon by photosynthesis and stores it on the seafloor. In terms of climate change, this is excellent news; seagrass is 35 times faster at removing carbon than tropical rainforests. When referred to global seagrass carbon stock estimates, the study indicates that seagrass in the Bahamas may contain 19.2% to 26.3% of all the carbon stored in seagrass meadows on Earth.

Yet seagrass meadows are rapidly disappearing, with over 92% of meadows in the UK gone, according to the World Wildlife Fund. Scientists are collecting seeds and trying to grow new seagrass meadows through restoration projects.

The sharks led us to the seagrass ecosystem in the Bahamas, which we now know is likely the most significant blue carbon sink on the planet. What this discovery shows us is that ocean exploration and research are essential for a healthy future. The untapped potential of the ocean is limitless, offering hope for climate change around the globe.

6 . With the new semester about to start, our school is welcoming a group of new international students. We have some apps here that will make your life easier. We hope you will have a wonderful life here.

★WeChat

WeChat is now the most popular social media app in China. Almost everyone is using WeChat. You can send both text and voice messages on WeChat. You can also make voice and video calls. You can also post texts, pictures and video clips. If your friends in your home country have this app, you can also chat with them through voice or video. WeChat is also widely used now as a form of payment which can be used in stores, online, and in other shopping apps.

★Alipay

Alipay is a similar app to PayPal. It was first used on Taobao and now people can still use it as a mobile payment option. You can even use mobile payment at street vendors, so if you have this app, you can leave your wallet at home.

★Didi

Now Didi seems to be the smartest way to travel around. With one tap, a car comes directly to you. Didi is a Chinese car-hailing service app. It has a function called “ride sharing”, which saves a lot of money for passengers. But it does not have an English version, so if you want to use it, you will have to learn some Chinese.

★Pleco

This is one of the top Chinese/English dictionary apps and it covers 130, 000 Chinese words and includes 20, 000 example sentences with pinyin. It is perfect for those who want to learn Chinese, and also for tourists who need to translate words or phrases from English to Chinese.

8 . How clever can a computer be? Maybe you can get the answer after reading the following passage about a newly-developed US computer program called Smarter Child.

If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can remember many facts. For example, Smarter Child knows every baseball player in every team this season and the weather in every city across the US. He also knows every word in the dictionary. However, if you ask Smarter Child other private questions, you will get strange answers. A question about Smarter Child’s age returns, “I’ll be older than you after further study!”, and asking where he lives, you will get, “In a clean room in a high-tech building in California.”

Smarter Child uses the huge information on the World Wide Web as his memory bank. To answer questions about spelling, for example, Smarter Child goes to www.ahdictionary.com. For the weather, he visits www.intellicast.com. He turns to www.the-scientist.com for scientists and www.moviefone.com for a fantastic movie.

Some scientists believe that by joining many systems of the Internet, an Artificial Intelligence (AI) with the combined (结合的) knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, Smarter Child has difficulty in discerning whether a behavior is right or wrong, which is obvious to any young child. If he wants to think and learn without any help from the programmers like boy-computer David in the movie Artificial Intelligence (AI), he must solve two problems.

The first is that computers find it difficult to read web pages because the files are sorted in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it by himself. Another problem is that while Smarter Child can deal with information more exactly and faster than any human, he needs programmers to make better systems that allow machines to solve problems of common sense, which is a huge challenge.
