2 . While many of us might long to just sleep through this entire winter, humans, unlike a lot of other mammals - don’t have the capacity to hibernate (冬眠). But researchers think they have found some tell-tale marks on the fossils, which suggests that early humans may have survived the harsh winter by hibernating.
Bears have specialized metabolic (新陈代谢的) processes to protect them from this extended sleep, but sometimes this process doesn’t quite go to plan. For example, hibernators can end up with a host of diseases after hibernation if they don’t get enough food reserves before they go down for the winter. The researchers believe this may have been the circumstance of some human ancestors whose remains with deep cracks in bones were discovered in a Spanish cave called Sima de los Huesos. This deep hole is home to an incredible number of fossils, with archaeologists having discovered thousands of early humans’ skeletal remains that are around 430,000 years old and probably the ancestors of the Sima people or others.
In a paper published in L’Anthropologie, two experts argue that the fossils found in Sima de los Huesos show seasonal variations that suggest that bone growth got interrupted for several months of each year. They suggest these early humans found themselves being in metabolic states that helped them to survive for long periods of time in extremely cold conditions with limited stores of body fat.
The researchers admit the idea “may sound like science fiction”, but they point out that many mammals including primates (灵长类动物) do this. “This suggests that the genetic basis and physiology for such slow metabolism could be preserved in many mammalian species including humans," state Arsuaga and Bartsiokas.
However, Chris Stringer of the Natural History Museum in London pointed out that large mammals such as bears do not actually hibernate, because their large bodies cannot lower their core temperature enough. Instead, they enter a less deep sleep known as torpor. In such a condition, the energy demands of the human-sized brains of the Sima people would have remained very large, creating an additional survival problem for them during torpor.

In China, 2024 is the Year of the Dragon, or “loong,” as is known in Chinese. This creature appears on many cultural artifacts
Unlike Western dragons,
For thousands of years, the Chinese have respected the loong,
At a historical site in Liaoning Province, a stone sculpture of a loong was discovered in 1994.
In much of Asia, especially the so-called “rice bowl” cultures of China, Japan, Korea,
Chopsticks are usually two long, thin
The Chinese have used chopsticks for five thousand years. People probably cooked
Some people think that the great Chinese scholar Confucius,

8 . Every day people joined archaeologists and artists in finding some of the year’s most dramatic discoveries. Below are some examples of 2023.
“Naughty pupils”-ancient punishment method resurfaces
Archaeologists discovered 18,000 ink-carved pieces of pottery-known as “ostraca”—at the site of Athribis early this year, and among them were hundreds of fragments(碎片)with a single symbol repeated front and back.
Those scribbles(潦草的文字)are evidence of ‘naughty “pupils” being made to write lines, according to researchers a Germany’s University of Tuebingen. The fragments also included receipts, school texts, trade information and lists of names.
Van Gogh peers out in hidden portrait
There is one more known van Gogh’s self-portrait in the world, and it was hidden behind a painting of a peasant woman. People made the discovery when they took an X-ray of one of his portraits from 1885 and discovered the artist’s own image behind layers of cardboard and glue. While X-rays often reveal how artists-changed their compositions, the full self-portrait of van Gogh came as a huge surprise, who was known to reuse canvase(画布)to save money.
Another treasure collection from Sanxingdui
The Sanxingdui archaeological site has produced thousands of relics. The latest discovery, reported by Chinese state media in June includes 3,155 objects, a turtle shell-shaped box and a sacrificial altar among them. A team has been digging six places of the site, turning up more than 13,000 objects so far. Last year, the relics they uncovered included a golden mask, ivory artifacts(手工艺品)and a jade knife. The Sanxingdui culture still remains mysterious, as it left behind no written records or human remains, though many believe it to be part of the ancient kingdom of Shu, which ruled along the upper stream of the Yangtze River until it was conquered in 316 BC.

9 . To us it seems so natural to put up an umbrella to keep the water off when it rains, but actually the umbrella was not invented as protection against the rain. Its first use was as a shade against the sun! Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honour. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was commonly used in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered as a symbol of power. By 1680, the umbrella appeared in France and later in England.
By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas did not change much in style during all this time, though they became much lighter in weight. It wasn’t until the twentieth century that women’s umbrellas began to be made in a whole variety of colours.
