1 . Consider the following statement: “My husband bought me a pink Lamborghini...” The correct way to finish the sentence, according to some, is not showing appreciation or acting excited, but to complain about the pricy gift. If you say, “The color is so ugly, men have such bad taste!” Congratulations, you have mastered the “Versailles (凡尔赛) literature.”

The term has nothing to do with the French palace nor with literature. It came from the Japanese manga series “The Rose of Versailles” and was coined by a Chinese influencer earlier this year. This new kind of bragging (吹嘘) is called humblebragging, the psychology behind which is to be recognized for one's successes and be liked by others at the same time. “The humblebragger recognizes that it's hard to be liked and be a showoff at the same time,” said psychologist Dr. Susan KraussWhitbourne at the University of Massachusetts Amherst.

In an article titled “Why people hate humblebragging” published in Psychology Today, Whitbourne noted that the humblebrag is a “strategy in pursuit of respect” because it draws attention to one's accomplishments, but in a roundabout (迂回的) fashion.

However, studies on social media users show that humblebragging, as a self-promotion strategy does not work. In the essay, “Humblebragging: A distinct-and ineffective-self-presentation strategy,” researcher Ovul Sezer concluded from his research that humblebraggers are perceived more negatively than straight braggers due to the former's insincerity. “The critical factor telling these strategies was sincerity. People don't like braggers, but they at least see them as more sincere than humblebraggers.”

“So, next time if you hear ‘My husband bought me a pink Lamborghini. The color is so ugly, men have such bad taste!’. Just pretend you don’t get whatever it is they try to show off.” a Zhihu user advised others on how to respond to a “pretentious narcissist”, “Respond with genuine sympathy for their complaint.”

3 . Research found that when people saw others in their herd (群体) hesitating before making a choice, they were about twice as likely to break from the group and make a different choice.

The findings have meanings for group behaviour in finance, fashion—any situation where there might be herd behaviour, Krajbich said. “Even if it appears at first that everyone is following the same trend, hesitation may show that they are not all on the same page,” he said.

The research studied 72 college students. They participated in groups of eight. When their predecessor (前任) responded slowly, participants chose against the herd about 66% of the time, compared to only 33% of the time when their predecessor chose quickly. In cases where the group was making the wrong decision, this often led people to break from the herd and make the correct choice, he said.

“A couple of bad decisions at the beginning can lead everyone to the wrong road. That’s the herd behaviour,” Krajbich said. “But what we found is that if people can see the hesitation in others’ choices, that can help them break the chain and change the course of the herd.”

Fast decisions by others can consolidate one’s own belief. For example, if a person sees their friends quickly choose to get a vaccine for COVID-19, that may make them more comfortable making the same choice, Krajbich said. If friends hesitate before getting a vaccine—even if they eventually get one—that may make a person less sure about whether to get the shot, he said.

Krajbich said the findings in the research aren’t necessary a universal rule. There may be some decisions for which taking longer to choose could indicate a more thoughtful choice. “It will be important to figure out when fast decisions signal confidence or when instead they signal thoughtlessness,” he said.

4 . In astronomy, star classification is governed by the Morgan-Keenen system, which categorizes stars based on their composition and surface temperature. The origins of this system can be traced back to the work of Annie Jump Cannon, a late nineteenth-century and early twentieth-century astronomer who spent over forty years classifying stars based on their unique spectra (光谱) of transmitted light.

Beginning early in her life, Cannon demonstrated an exceptional talent for the physical sciences. As a child, she developed an interest in astronomy and transformed her study into a temporary observatory. Later, as a student at Wellesley College, Cannon earned a degree in physics and became an expert in spectroscopy, the process by which light is separated into its component wavelengths. During this period, she also took up photography and traveled extensively in order to experiment with the newly invented black-box camera.

Cannon’s background in physics, astronomy, and photography provided her with a unique skillset that would serve her well for the rest of her career. After working as a research assistant for a number of astronomers at Wellesley and Radcliffe Colleges, Cannon was hired by Professor Edward Charles Pickering, the director of the Harvard College Observatory. Under Pickering, she classified over 300,000 stars — more than any other human in history — using only a telescope, a spectrometer, and a camera. Using this knowledge, she developed her own classification system that relied on the surface temperature of the stars, which could be accurately estimated using the spectra of light transmitted from stars. It was said that Cannon could classify three stars a minute and, using a magnifying glass, could classify stars down to the 9th magnitude — sixteen times fainter than what can be seen by human eyes.

Today, Cannon’s unique classification system is used by countless astronomy enthusiasts around the world. Harlow Shapley, the astronomer who succeeded Pickering, once referred to Cannon’s contribution to astronomy as “a structure that probably will never be duplicated (复制) in kind or extent by a single individual.”

As a distinctive visual art symbol of China, Chinese paper cutting, has been around for centuries. With     1     (simple) a piece of paper and a pair of scissors, diverse patterns ranging from portraits to animal zodiacs     2     (create) with delicate designs.

Due to their     3     (culture) value and low cost, Chinese paper cut-outs are popular ornaments used to decorate windows and mirrors. When light shines through the negative spaces of the cut-outs,     4     elegant pattern is formed indoors.     5     (refer) to as ‘window flowers’, the pretty cuts outs decorating windows are significant in Chinese traditional culture.

The oldest     6     (survive) paper cut-out is a symmetrical (对称的) circle from the 6th century found in Xinjiang, China. The art of Chinese paper cutting is believed     7     (originate) in China even before the invention of paper by Cai Lun in 105 CE. There have been documentaries     8     record the Chinese using other thin materials such as leaves, silk, and leather to carve hollowed patterns. It was found that during the Western Zhou Dynasty (1046–771 BC), people had already cut tree leaves into various art forms     9     given them out as presents. They created paper-cuts to depict beautiful things, worship, and express good     10     (wish) .

10 . The history of the school bus can date back to 1886 when the Wayne Works company made horse-drawn carriages (四轮马车) known as “ school wagons” or “kid hacks” in Indiana.     1    

In the early 1900s, the car industry was beginning to develop fast.    2     The company managed to make its carriages powered by engines. But the design remained mostly the same as that of the previous ones, with students sitting along the walls of the bus while facing inside.

In 1927, a man built the first bus that primarily used steel. Before long, Wayne Works introduced the first all-steel school bus body with safety glass windows.     3     This led to a turning point in the history of the school bus in 1939, when a conference was organised at Manhattan College to develop school bus standards.

Many new national standards were created, determining everything from seating designs to the famous yellow color that school buses still sport today. The reason why the color was chosen was simple.     4    The color is especially easy to see in the early morning and evening light when school buses usually operate.

    5     For example, a variety of changes have been made to enable the school bus to not only be safer but also have better fuel (燃料) economy, be easier to drive, etc. The most creative approach among all of these is probably a kind of stop signal arm that warns traffic of a stop in progress, which states began to require in the early 1950s.
