1 . Abstract art, a genre often misunderstood and deeply involved in argument, challenges the traditional norms of visual representation. It resists simple explanation, making viewers connect with the artwork in a more thoughtful and emotional way. This style of art, eschewing (避开) literal depiction, instead uses shapes, colors, forms, and gestural marks to achieve its effect.

The genesis of abstract art can be traced back to the early 20th century, a period marked by rapid technological advancements and significant societal changes. Artists began to move away from realistic portrayal, seeking new ways to express the complexities of the modern world. Pioneers like Wassily Kandinsky and Piet Mondrian broke away from traditional techniques, favoring a more subjective approach that emphasized inner feelings over external realities.

Kandinsky, often hailed as the father of abstract painting, believed that art should be free from the constraints of representational accuracy. He advocated for the use of color and form as tools to evoke emotion, asserting that they possessed an intrinsic spiritual value. Mondrian, on the other hand, focused on reducing art to its basic elements – a style he termed Neoplasticism (新塑造主义). His compositions, characterized by horizontal and vertical lines intersecting at right angles, sought to achieve a sense of harmony and balance.

In the ensuing years, abstract art evolved into various movements and styles, each offering a unique perspective on the non-representational aesthetic. Movements like Abstract Expressionism, led by artists such as Jackson Pollock and Mark Rothko, emphasized the creative process and the physical act of painting. Pollock’s drip paintings, made by spreading and dripping paint onto the canvas, showed the movement’s lively and energetic nature.

Despite its evolution, abstract art has often been met with skepticism. Critics argue that its lack of clear, recognizable forms makes it inaccessible to the general public. However, proponents of abstract art contend that its value lies in its ability to transcend language and cultural barriers, offering a universal form of expression that connects with the viewer on a subconscious level.

The impact of abstract art extends beyond the confines of the art world. It has influenced various fields, including architecture, design, and fashion, underscoring its significance as a revolutionary force in the realm of creative expression.

SPACE: THE FINAL FRONTIER

“Are we alone? What’s out there?” People have always looked up at the stars and wondered about space. Today, scientists design vehicles to carry astronauts into space to make important discoveries.Space exploration has come a long way, and we now hope to discover other planets that are suitable enough to support life.

Before the mid­20th century, most people felt travelling into space was only a dream that could never come true. However, scientists were determined to realise that dream. After many experiments, they succeeded in making rockets that could escape Earth's gravity. On 4 October 1957, the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to enter space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, “That’s one small step for (a) man, one giant leap for mankind.” Following this, there were many more important space achievements. For example, on 5 September 1977, America’s NASA space agency launched Voyager 1 to study deep space, and it still transmits data to this day. And the International Space Station (1998) has provided a continuous human presence in space, with astronauts from many different countries on board.

Although scientists try to make sure nothing goes wrong, accidents can still happen. For example, all the astronauts on the Soyuz 11, Challenger, and Columbia spacecrafts died during their missions. However, while such disasters brought much sadness and disappointment, the desire to explore the universe did not die. This is because people believe in the importance of carrying on space exploration despite the huge risks.

China’s space programme started later than those of Russia and the US, but it has made great progress in a short time. China became the third country in the world to independently send humans into space in 2003, when Yang Liwei successfully orbited Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk, followed by the vehicle Jade Rabbit being sent to the moon to study its surface. On 23 July 2020, China sent Tianwen 1 to explore the surface of Mars. It arrived in February 2021 and then sent back lots of valuable information. And from 2021 to 2022, China completed a number of rocket missions to establish its own space station. In 2022, the launch of the Mengtian module signaled the basic completion of the Tiangong Space Station. This modern space station will allow astronauts to conduct many important experiments, greatly furthering our understanding of the universe.

The future of space exploration remains bright. Many countries have plans to further study planets like Mars and Jupiter. Despite the difficulties, scientists hope to make more valuable discoveries that will enable the human race to survive well into the future.

Today was my first day back in San Francisco after camping in the Redwood Forest and visiting the wine country of Napa Valley. I have to admit that it definitely feels good to be back in the city again. And what a city—a city that was able to rebuild itself after the earthquake that occurred in 1906. There are so many beautiful old buildings—many siting on top of big hills, offering great views of the city, the ocean, and the Golden Gate Bridge.

My hotel is near downtown, in the Mission District, one of the oldest parts of the city. Many of the people living here are from Mexico or Central America. This district used to be a poor area of town, but is now a centre for art, music, and food. In fact, an art movement called the “Mission School” started here. It’s influenced by graffiti art and comic art. I walked around looking at the street art for a few hours. It was quite modern and lively. Afterwards, I ate some delicious Mexican-Chinese noodles from a food truck. A real mix of cultures here!

In the afternoon, I headed to a local museum that showed the historical changes in California. I learnt that America got California from Mexico in 1848. In the same year, gold was discovered near San Francisco, which started a gold rush. Over 300,000 people came from all over the world to seek their fortune, and San Francisco quickly became a big city. Many Chinese arrived during this period. To earn a living, some opened up shops and restaurants in Chinatown. Many others found jobs on farms, joined the gold rush, or went to build the railway that joined California to the eastern region of the country. The museum did a really good job of showing how America was built by immigrants from different countries and cultures. When these immigrants left their countries, they carried a bit of home in their hearts, and built a new home here.

This evening, I went to Chinatown. There were so many cafés and restaurants to choose from. I selected a Cantonese restaurant that served its food on beautiful china plates. What great food! That’s enough for today. Tomorrow evening, I’m going to a jazz bar in the Richmond Distinct. Can’t wait!

8 . 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.

10 . In the Pixar movie Up, a fun cartoon dog called Dug wears a magical collar which can detect and translate his barks and cries into fluent human speech. Humans have always been fascinated by the potential to communicate with the animals. This week, an article in the New York Times documented major efforts from a group of researchers using machine-learning algorithms (算法) to analyze the different calls of whales, chickens, bats, cats, and more.

There are several ways to train AI systems now. Typically, Al systems learn through training with labeled data of human language which can be well supplied by the Internet. But analyzing animal language is different. Scientists have to instruct software programs on what to look for, and how to organize the data. This process requires matching gained vocal (发声的) recordings with the visual social behaviors of animals. A group studying Egyptian fruit bats, for example, also used video cameras to record the bats themselves to provide context for the calls.

Many critics of this approach point out two weaknesses of current AI language models: being unable to truly understand the relationships between words and the objects in the real world, and scientists’ little understanding of animal societies. Al language models for humans rely on a computer mapping out the relationship between words and the contexts they could appear in. But these models have their own weak points, and can sometimes be a black box—researchers know what goes in and comes out, but don’t quite understand how the algorithm is arriving at the conclusion.

Another factor that researchers should take into account is that animal communications might not work at all like human communications. There might be unique elements to animal language due to physiological and behavioral differences.

Making a Translator for animals has been a popular project that’s been in the works for the last decade. Although some software has shown some success in identifying the basic vocabulary of certain animals, it’s still a far cry from understanding the complex animal languages.
