4 . Minor Cold: A sugary feast to get through the freezing winter

Minor Cold, or “Xiaohan” in Chinese, is the 23rd of the 24 solar terms in the Chinese lunar calendar     1       We’ve outlined below how people deal with the Minor Cold and its significance in Chinese culture.

Eight treasures rice pudding or “babaofan” in Mandarin is a special sweet rice dish enjoyed during Minor Cold and Chinese New Year dinner. In Chinese, the number eight is pronounced as “ba”, which is similar to another Chinese word “fa”.     2    . Because of its pronunciation, this traditional Chinese dim sum is regarded as a symbol of wealth and health.

    3    . Different regions in China have different eating habits. People in Nanjing and Shanghai usually cook vegetable rice while in Guangzhou, it is a tradition to eat sticky rice on the morning of Minor Cold.

For Chinese people, this time of year also sees preparation for the most important festival of the year: the Spring Festival.     4    . In the old days, Chinese families would usually start to purchase the necessities for the Spring Festival, write couplets and make paper cuts by themselves.

The ancient Chinese noticed the slight changes in seasons by observing the movements of the birds. Wild geese would usually start to fly back to the north while the magpies (喜鹊) make their nests. These animals remind people of the beginning of the suitable farming and life for Minor Cold.     5    . Therefore, more attention should be paid to domestic animals’ warmth.

5 . A community canteen at the Zhanongkou Community in Shangcheng, Hangzhou recently launched “happiness blind boxes”, which cost just 6 yuan per box. Sales start at 7 p. m. each evening.

The dishes are packaged in transparent (透明的) containers, but to maintain an element of surprise, stickers are placed over the lid (盖子) of the “main dish” section of each box. The “blind boxes” have become popular since being introduced, and on some nights they sell out by about 8 p. m.

A meal assistance program introduced in Zhanongkou subdistrict ensures the elderly can access meals within a 10-minute walk of their homes or have them delivered within five minutes. The service has also been welcomed by younger people living and working in the area.

Yan Xuyang, a professor at Beijing Union University’s Tourism College, predicts that by 2035, those born from the 1970s to the 2000s will comprise the main group of customers for such canteens. “This generation has a reasonable level of disposable (可自由支配的) income, and many of its members may also lack the willingness to prepare meals for themselves,” Yan said.

The successful operation of community canteens depends on their ability to integrate into the daily lives and culture of local residents. In addition to serving dishes to suit local tastes and fostering a welcoming environment for diners, it is important to widen the functions of these canteens. They have been used for cultural activities and other events, which helps raise awareness and foster a positive perspective on these canteens among local communities.

In the latter part of last year, the Weikang community canteen in Ziyang subdistrict, Hangzhou, experienced a significant transformation from being a canteen for seniors to catering for the whole community. Its services have been broadened beyond regular operations to include services for hospitals and businesses, complete with home delivery options. Some other community canteens have also made efforts to appeal to more residents.

6 . Each year, the discovery of new shark species underlines how little we know about ocean biodiversity. In a recent report conducted by Sibert and Rubin, they reported an unexpected finding: a large-scale extinction of sharks in the pelagic ocean, the largest ecosystem on Earth, about 19 million years ago. Their discovery suggests that some extinctions in the open sea of the past may have been mysterious.

The study of Sibert and Rubin takes advantage of a system by using tiny, hard bits of shark skin and bony fish teeth that naturally fall from their bodies to the seafloor. These extremely small fossils provide a rich record of ancient oceanic sharks and their abundance for thousands of years. By studying fossils from many regions, the diversity patterns can give major insights into evolution (进化) of the open sea that would be otherwise unknown.

Sibert and Rubin quantified(量化)a past extinction of sharks, reporting a 90% decline in number and >70% drop in diversity. They found that nearer-shore sharks appear to survive, but migratory ones go extinct. The finding of this study is that sharks had undergone a widespread extinction that reorganized their communities from 16 million to 20 million years ago.

Sibert and Rubin narrowed the disappearance of sharks to a window of time under 100,000 years around 19 million years ago, but the causes of this event remain unclear. Because this time period does not stand out as a period of major climatic change, the authors do not attribute(归因于) environmental factors as an extinction driver. As for other causes, the loss of shark diversity is directly linked to overfishing.

The loss of sharks from the oceans has profound, complex, and unavoidable ecological consequences because their presence reflects the stability of marine ecosystems. Yet, one-quarter of the global diversity of sharks is currently threatened with extinction. Despite recent improvements in conservation actions, shark communities never recovered from a mysterious extinction event 19 million years ago; the ecological fate of what remains is now in our hands.

7 . Books are the most valuable cultural heritage. However, there are many ancient Chinese classics suffering from different degrees of damage due to various reasons.     1    

Bai Yuzhi,a post-90s restorer (修复师) at the Wuhan Library,graduated from Wuhan University in 2016 with a major in restoring ancient books. She is now the fourth generation of restorers at the Wuhan Library, Bai started practicing this technique during her after-class activities at college in 2014.     2     “I’m shy and not good at socializing, so this job suits me very well,” she said

    3     The restoration steps cannot be rushed. When restorers receive an ancient book, their first task is not to directly restore it but to observe it and record the book’s important details. After that, the restorers will open the book,remove every page, and repair it on the back side.     4     It may take one or two days to restore a single page. So it could take at least a month to complete the restoration of a whole book.

Bai has restored about 10,000 pages of ancient books in her over 10 years of work. The most difficult part of the restoration, according to her, is keeping everything under exact control over every stage.     5     If the paste (面糊) is too thin, the repaired pages may easily come off and become broken, which could affect the quality of the restoration. However, if the paste is too thick, the fixed pages will be tough, challenging to open.

With the advancement of science and digital technology, the methods for protecting ancient books have become more various.

8 . Working for a big company in London on a salary (薪水)of over £100,000, you might expect Grayden Reece-Smith to have a luxurious (奢侈)lifestyle, going on expensive holidays or driving a sports car around south London, where he lives. In fact, the 28-year-old lives a very different existence from his colleagues. He gives away everything he earns over £42,000–a figure that he thought he could comfortably live on.

Over the past five years, Reece-Smith has handed over more than £250,000 to organizations such as International Care Ministries, which helps poor families in the Philippines, and the Against Malaria Foundation. He is part of a growing number of young professionals described as “effective altruists”. Effective altruists typically donate regularly to a charity which they think will have a great impact (影响). Some change careers to make more money, which can then be given away.

Reece-Smith considered working in the charity sector after graduating from university, but thought that he could make a bigger difference by donating a large part of his salary. He had volunteered as a teacher at a school in Tanzania, but then realized that earning and giving would be more effective. “The cost of my flights there could have paid the salaries of two teachers for an entire year,” he says. Instead, he could “stay at home, living a nice life and still make a huge difference in the world”.

He is not mean with money-last year he went to Cuba on holiday, and spent several thousand pounds on a new sofa. But his lifestyle isn’t as luxurious as some of the people he works with. “I usually don’t buy supermarket-branded food products, but I don’t own a car. Other people on my salary might have a bigger house. Some of my colleagues have four-bedroom houses, but we only bought what we needed-a two-bedroom flat.£42,000 is more than enough to live on and still save,” he says.

9 . When handball was introduced to Sri Lankan schools in 2010, I wanted to bring it to my school in a remote village. This became a(n) _______ task as the sports teacher was unwilling to initiate anything _______ traditional sports like basketball. Despite being an English language teacher before _______ my post as deputy principal (副校长), I was _______ to start this game at any cost.

40 students aged between 13 and 19 _______ to play. I had the support of their parents but I still couldn’t _______ the sports teacher to agree. _______ , I used my position to get the game going.

Heshan Pradeep, an alumnus (校友) and member of the Air Force handball team, volunteered to _______ the team. Although handball is an indoor game, we trained outdoors due to limited _______. Training started early in the morning before class and ________ after school until it was dark. The boys loved the game and were ________ training. After three months of devoted training, we were able to send an under-19s boys’ team to ________ with 50 other schools. Our boys played remarkably well and ________ the semifinals. The following year, nobody could ________ our team from winning the all-island schools handball championship.

The ________ sent the whole village into carnival mode. Heshan and I were much honored to have shown the boys that dreams can be fulfilled.

10 . When I first met Nao Junior, he was in his 40s and one of only nine members of his Indigenous(土著的) group, Great Andamanese, who still spoke the idiom of his ancestors. As a language specialist, I had researched more than 80 Indian languages. I was on the islands to document their Indigenous voices before they faded into whispers.

Words in this language consisted of two classes: free and bound. The free words were all nouns that referred to the environment and its inhabitants, such as ra for “pig”. They could occur alone. The bound words were nouns, verbs, adjectives and adverbs that always existed with markers indicating a relation to other objects, events or states. The markers came from seven zones of the body and were attached to a root word to describe concepts such as “inside”, “outside”, “upper” and “lower”. For example, the morpheme(词素) er-, which qualified most anything having to do with an outer body part, could be stuck to -cho to yield ercho, meaning “head”.

Just as a head, a bound word, could not conceptually exist on its own, the mode and effect of an action could not be divided from the verb describing the action. Great Andamanese had no words for agriculture but a great many for hunting and fishing, mainly with a bow and arrow. Thus, the root word shile, meaning “to aim”, had several versions: utshile, to aim from above; arashile, to aim from a distance; and eshile, aiming to make a hole with a sharp object.

The studies established that the language seems to be truly old in origin. In a multistage process of development, words describing diverse body parts had changed into morphemes referring to different zones and combined with content words to yield meaning. The structure alone provides an insight into an ancient worldview in which the macrocosm(宏观世界) reflects the microcosm, and everything that is or that happens inseparably connects to everything else.
