On Feb 8, 2001, workers at a construction site in Jinsha village, Chengdu, found many pieces of ivory and jade and the hidden ruins of the capital of the ancient Shu Kingdom were brought     1    light by archaeologists. Among the over 5,000 precious relics     2    (excavate)from the ruins, the most eye-catching is the Golden Sun Bird. It is made from delicate gold foil(箔), just one     3    (five)of a millimeter thick. It has two sections: The center is a sun pattern with 12 rays     4    (indicate)the rotation(自转)of the sun and around the sun are four birds flying anticlockwise. According to archaeologists, the four birds symbolize four seasons, while the 12 rays     5    (mean)to represent 12 months of the year. Hence, it could be inferred that over 3000 years ago ancient Shu people possessed     6     good knowledge of astronomy and nature. Furthermore, this masterpiece is believed to be an illustration of an ancient Chinese myth recorded in the classic The Legends of Mountains and Seas,     7     was written about 2,500 years ago. According to the book, ancient people believed the sun was carried up     8    down by birds daily.

In 2005, the pattern was     9    (successful)selected as the symbol of China’s cultural heritage to showcase the ancient Chinese people’s     10    ( wise)and aspirations.

2 . 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.

3 . Frozen in time, a 125-million-year-old mammal attacking a dinosaur. A 39-million-year-old whale, the heaviest animal that ever lived. The oldest known jellyfish, from 505 million years ago. Paleontology (古生物学) produces newsworthy discoveries.

Fossils (化石), moreover, provide direct evidence for the long history of life, allowing paleontologists to test hypotheses (假设) about evolution with data only they provide. They allow investigation of present and past life on Earth. Flows of biological diversity, appearances of new life forms and the extinctions of long existing ones, would go undiscovered without these efforts. But the headlines over exciting new fossils greatly underestimate the true importance of paleontology. Its real significance lies in how such discoveries brighten the grand history of life on Earth. From its beginnings, more than three billion years ago, to the present day, fossils record how life adapted or disappeared in the face of major environmental challenges.

Paleontologists provide us with a unique vantage on modern climate change. They play an essential role in interpreting ancient environments, in reconstructing ancient oceans, continents and climates. Fossils provide key limitation on the climate models that are essential for predicting future climate change. And the fossil record gives important insights into how life will respond to predicted future climate conditions, because these have occurred before in Earth’s history.

In addition, paleontology has provided a fundamental contribution to human thought: the reality of species extinction and thus of a world that has dramatically changed over time. In documenting the history of life, paleontologists recognized that many extinction episodes could occur suddenly, such as the event 66 million years ago that ended the dinosaurs. The search for the causes of past mass extinctions started pioneering studies from across the scientific spectrum (科学界), focusing on potential future threats to humanity.

Not only do paleontologists know what happens to life when things go bad, they also know how long it takes for ecosystems and biodiversity to recover from these disasters, which can take far longer than modern humans have existed.

Paleontologists thus provide a unique perspective on the nature and future long-term ecological impact of the current human-produced biodiversity crisis, the so-called Sixth Extinction, and therefore the importance of protecting modern biodiversity. The very concept of a Sixth Extinction would not exist without paleontologists documenting the first five.

Paleontologists know that understanding life’s past is critical to anticipating and adapting to life’s and humanity’s future. Paleontology is important because it brings its unique and critical perspective to current challenges in climate change, biodiversity loss and the environment. Paleontologists can predict the future because they know the past.

6 . Archaeologists in Mexico have discovered the remains of a lost Maya city hidden deep within the jungles of the Yucatán Peninsula.

The site, located in the Balamkú ecological reserve in the Mexican state of Campeche, contains numerous large pyramids that were built during the Classic Period of the Maya civilisation. The archaeologists named the location Ocomtún, meaning “stone column (石柱)” in Yucatec Maya language, in a nod to the many stone columns spreading around on the over 123-acre site.

The team found the city while mapping the Maya lowlands with billions of lasers shot from an aircraft flying overhead. This technique, known as light detection and ranging, is a noninvasive (非创伤的) way for researchers to understand the geography of human-made structures hidden beneath leaves. In this case, the technique revealed a Maya city with several pyramidal structures, with the tallest towering nearly 50 feet.

“The site serves as an important center at the regional level,” lead archaeologist Ivan Šprajc said in the statement, “and it is a breakthrough in Maya archeology.”

The Maya had numerous city sites spread across southern Mexico and Central America; the civilization reached its peak during the first millennium AD until it “collapsed” between 800 and 1000. In addition to finding the pyramids and columns, while on foot, the archaeologists discovered ceramics (陶瓷), three squares, a court used to play ball games and a complex comprising low and thin structures arranged almost in circles.

However, the archaeologists are still investigating how the Maya used some of the structures. “It is possible that they are markets or spaces designed for community events,” Šprajc said. “The most common ceramic types that we collected on the surface and in some test pits are from the Late Classic. However, the analysis of samples of this material will offer us more reliable data on the sequences of occupation.”

7 . That dinosaurs ate the mammals (哺乳动物) that ran beneath their feet is not in doubt. Now an extraordinary fossil newly described in Scientific Reports, unearthed by a team led by Gang Han at Hainan Vocational University of Science and Technology in China, shows that sometimes the tables were turned.

The fossil -dated to about 125 million years ago, during the Cretaceous period-was formed when a flow of boiling volcanic mud swallowed two animals seemingly locked in a life-and-death fight. The one on top is a mammal. This animal is a herbivorous species closely related to the Triceratops (三角恐龙). Animal interactions such as this are exceptionally cam e in the fossil record.

One possibility is that the mammal was eating something already dead, other than hunting live prey. These days it is uncommon for small mammals to attack much larger animals. But it is not unheard of. And Dr. Han and his colleagues point out that those mammals which eat dead bodies typically leave tooth marks all over the bones of the animals. The dinosaur’s remains show no such marks. There is also a chance the fossil could be a fake. More and more convincing fake s have emerged, as this one did -though Dr. Han and his colleagues argue that the complexly connected nature of the skeletons (骨骼) makes that unlikely, too.

Assuming it is genuine, the discovery serves as a reminder that not all dinosaurs were enormous during the Cretaceous and not all mammals were tiny. From nose to tail, the dinosaur is just 1.2 meters long. The mammal is a bit under half a meter in length. Despite being half the size, the mammal has one paw firmly wrapped around one of its prey’s limbs, and another pulling on its jaw. It is biting down on the dinosaur’s chest, and has ripped off two of its ribs. Before they were interrupted, it seems that the mammal was winning.

9 . In 1986, thirteen tombs were found in Fangmatan, an area that lies close to the city of Tianshui in China’s northwestern Gansu Province. Most were built during the Warring States Periods (475-221 B.C.). The tombs were located in Gui County, which lay within the territory of the state of Qin.

What the archaeologists found in one of the tombs was quite a surprise — seven maps that, through a fortunate coincidence, had survived for more than 2,200 years. This early date makes them the oldest known surviving maps from China.

After two years of difficult work, specialists managed to restore the maps and bring all their details back to light. The seven maps were drawn with black ink on four rectangular slabs (平板) of pine wood. The pieces all measured almost the same size. Each is about 10.5 inches long, 7.13 inches wide, and 0.43 inch thick.

These maps offer positive proof of how advanced the art and science of mapping was in China at the time. They include information about both the administration and the geography of Gui County. They also include the longitude and latitude of the area, as well as the most characteristic elements that are marked on today’s maps. Less important areas are simply named and have no lines drawn around them. Also labeled on these maps are roads, mountains, and rivers.

When you take a closer look, you will note another fascinating feature. The forests in Gui County are also defined. Interestingly, we can even recognize markings that describe the types and sizes of the timber (木材) to be found in the several areas. This information offers valuable insights into what the local plant life looked like during that time.

But that is not all. In some cases, even the distances from the forests to the settlements are marked. Can you guess why? Well, timber was an important commodity (商品), and it had to be transported. The Fangmatan maps include everything that was necessary for the organization of such journeys and business dealings. Taking all this into consideration, they clearly served as economic maps for traders.

Two young Chinese athletes placed a torch in the center of a giant snowflake during the opening ceremony of the Beijing 2022 Winter Olympic Games. One of the two athletes, Dinigeer Yilamujiang, was born in the Altay Prefecture,    1    (locate) in the northern part of the Xinjiang Uygur Autonomous Region,    2    (wide) acknowledged as the birthplace of human skiing.

In earlier times, artifacts from Scandinavian and Russian archaeology proved the    3    (exist) of ancient skiing, with the oldest found in Russia    4    (date) back to 7,000-8,000 years ago. In 2005,the record    5    (break). A group of farmers in the Altay region went to a cave to hide from the rain,only    6    (find) cave paintings describing men stepping on twin snowboards    7    prey（猎物）carried on their backs. It turned out that， according to archaeologists’ analyses, the cave paintings were drawn 12,000 years ago, some 4,000 years     8     the artifacts from Russia that were believed to have been made.

After Beijing’s successful bid to host the Winter Olympics, experts from 18 countries including Norway and Russia paid a visit to Altay to study the “potential origin of human skiing activity, ” after    9    they jointly issued a declaration in 2015, recognizing Xinjiang's Altay as the    10    (early) skiing region in the world.
