1 . Human faces cut into stone up to 2,000 years ago have again been found on a rocky area along the Amazon River in northern Brazil. The stone carvings (雕刻品) appeared as a result of a big drop in water levels because of dry weather in parts of northern Brazil. The water level had dropped to the lowest level in the history of the river.
“People had reported some of the stone carvings before during periods when water levels were low. But now a greater number have been identified. That will help researchers establish the history of the carvings, and more secrets of historical relics will come to light,” researcher Jaime de Santana Oliveira said recently.
One area shows smooth marks in the rock thought to be where natives once sharpened their tools such as arrows and spears before European settlers arrived.
“The carvings are prehistoric, or precolonial (殖民地时期前的). We can’t be sure of their precise date but based on the evidence of human living places of the area, we believe they are about 1, 000 to 2, 000 years old.” Oliveira said.
The rocky area is on the north shore of the Amazon River near the place where the Rio Negro River joins it.
Oliveira said the carvings were first seen in 2010, but this year’s drought has been more serious than earlier dry periods. The Rio Negro’s levels have dropped 15 meters since July, uncovering large areas of rocks and sand where there had been no beaches.
“This time we found not just more carvings, but the statue of a human face cut into the rock,” said Oliveira, who works for the Brazilian government’s National Historic and Artistic Heritage Institute. The organization watches the care of historic places in Brazil.

2 . Lisa St. Coeur Cormier, a high school science teacher in Prince Edward Island (PEI), Canada, found a tree root. When she took a closer look, she found the shape was very strange. She realized it wasn’t a tree root though it shared the same color. She felt it was hard to break and noticed an impression of bones of what looked like some kind of animal.
Cormier sent a photo of the find to Laura MacNeil who used her knowledge in this field to confirm that what Cormier had seen really was a fossil (化石). MacNeil runs tours of sites where prehistoric fossils have been found and also helps people identify fossils. She visited the site of Cormier’s find to take more photos of it.
MacNeil contacted John Calder, a scientist, who examined the fossil and led a team of scientists to study it. John Calder said it could be as much as 300 million years old. He said it’s probably from a reptile (爬行动物) of some kind — likely one that is unknown to scientists. Scientists spent 5.5 hours carefully digging out the fossil from the ground so they could study it more in-depth and find out exactly what kind of animal it is. That research could take a year or more.
“This is an important discovery here on Prince Edward Island. It is the second of the only two articulated skeletons (关节相连的骨头) found on PEI,” Laura MacNeil said. “This creature lived about 300 million years ago. This find tells us there is a great possibility for future scientifically important fossils that could be discovered on PEI. It will lead to more researchers paying a visit.”

6 . Stonehenge is hiding a secret: the source of one of its stones.
Researchers know that the prehistoric circle’s outer stones come from nearby areas in England. But even after a century of study, the Altar Stone near the center of Stonehenge remains difficult to understand.
The Altar Stone belongs to a group of Stonehenge building blocks known as the bluestones, which came from areas far from Stonehenge. Researchers have found that some of the bluestones come from as far as 225 kilometers away.
“It’s a massive job of transport,” says Richard Bevins, an earth scientist at Aberystwyth University in Wales. His team is looking for the source of the Altar Stone. Uncovering the stone’s origins could suggest which ancient groups of people contributed to the building.
Scientists have been working to find the rock’s origins since 1923. A report about the Altar Stone’s minerals back then suggested it might have come from a set of rocks in Wales near where other bluestones cane from. Bevins’ team decided to revisit the rock’s riddle with modern techniques.
In 2021, the team analyzed (分析) the Altar Stone’s chemical makeup using X-rays. The X-ray method showed that the Altar Stone has high levels of the element barium (钡). But the stone’s makeup didn’t seem to match the rocks in Wales.
In the new study, the team collected 58 samples (样本) from a wider area in England and Wales. Of the 58 sample stones, four had high barium levels similar to the Altar Stone. The team then compared the overall mineral makeup of those four stones with the Altar Stone. But none were a match.
“Maybe we’ve been looking in the wrong area, and maybe we’ve possibly been looking at rocks of the wrong age,” Bevins says, “It’s not clear exactly how old the Altar Stone is.” So scientists may need to consider stone sources that are younger than the ones they have looked at so far.

8 . Several cultural relics unearthed from the Haihunhou tomb in Nanchang have been confirmed to be official documents presented to the imperial court. The three pieces already released were all written with ink, according to the Nanchang Evening News.
Based on the analysis by Zhang Yuzheng, an expert at Beijing Union University, the relics may be the oldest original copies of senior official documents in the Han Dynasty (BC 206-AD 220), which have great value for the study of ancient official documents.
Among the three publicly released relics, two of them remain fairly intact with exact date information, though the handwriting is partly damaged. Chinese characters meaning “concubine (妾)” and “Haihunhou He” can be seen on the relics, which show that they were written by the Marquis of Haihun Liu He and his concubine.
Zhang Yuzheng suggested that according to Haushu, the documents presented to the imperial court should be in two copies, with the original copy submitted to the emperor and the copy to the minister. The minister would first review the contents and then decide whether it was appropriate to be submitted to the emperor. The system was ended during the reign of Emperor Hanxuan in the Han Dynasty. The unearthed relics from Haihunhou tomb are believed to have been written on the fourth year of Yuankang during the reign of Emperor Hanxun when the system was already ended.
Therefore, Zhang holds that the unearthed relics written with date information “fourth year of Yuankang” were very likely the original copies of official documents, instead of copies.
The whole structure and content are also complete, the handwriting is quite neat, and the format (格式) is strict, consistent with the features of an original copy, according to Zhang.
1. What can we know about the three released relics?| A．They were official documents by senior officials. |
| B．They proved to be the oldest documents in the Han Dynasty. |
| C．They were recognized as Liu He and his concubine’s handwriting. |

| A．Complete. | B．Meaningful. | C．Organized. | D．Reliable. |
| A．The valuable relics kept until today. |
| B．How the relics were presented to the imperial court. |
| C．What information should be included in the official document. |

9 . What killed King Tut? Historians and scientists have long believed that ancient Egypt’s most famous king was probably murdered. But a recent scientific study claims to have found a different answer to this more than 3,300-year-old mystery. A team of researchers now say that King Tut, the boy ruler, died of complications (并发症) from a broken leg.
Tut’s full name was Tutankhamun. He was just 9 years old when he became the ruler of Egypt. His treasure-filled tomb was discovered almost a century ago. It was filled with royal riches, including a solid-gold coffin, a gold mask, and piles of jewelry.
Unfortunately Tut died at the age of 19. Many experts have thought that Tut was killed by one of his advisers, named Ay, who wanted to be king. But thanks to a major modern science project, it seems Ay is innocent.
Researchers set out to solve the mystery of King Tut’s death by using the tools of science, including DNA tests and electronic scans of his mummy (木乃伊). Scientist Carsten Pusch conducted the tests on Tut for the new study. He thinks a broken leg contributed to the young king’s death.
More than 100 walking sticks were found in King Tut’s tomb. This supports the team’s findings. But how could a person die from a simple broken leg?
Pusch also found DNA evidence in Tut’s body that indicates he had malaria (疟疾), a disease carried by mosquitoes. Malaria severely weakens the immune system.
Pusch and his fellow researchers believe the malaria and the bone disease together caused the king’s fracture (骨折) to become deadly. Finally, the young king was just too weak to recover. So effects of the disease combined with the bad luck of a broken bone — not a jealous adviser — are likely the real causes of King Tut’s death.
