More than 500 items were discovered at Sanxingdui Ruins site in southwest China’s Sichuan Province. These items, including remains of a gold mask,     1    (dig) in one of China’s     2    (significant) excavations(n. 发掘) ever.

Sanxingdui is believed to have sat at the heart of the Shu state,     3     historians know relatively little about due to rare     4    (write) records.     5    (discovery) made at the site date from the 12th and 11th centuries BC, and many of the items are now on show at an on-site museum. The site has changed experts understanding of     6     civilization developed in ancient China.

Archaeologists(考古学家) realized they had just got     7     excellent chance to study ancient culture     8    (date) back between 3,000 and 5,000 years.     9     particular, evidence of a unique Shu culture suggests that the kingdom     10    (develop) independently of neighboring societies in the Yellow River Valley, which was traditionally considered to be the cradle(摇篮) of Chinese civilization.

4 . Like many of the arts, music flourished during the Zhou dynasty. From this period we have instruments, models of performers, descriptions of musicians and dancers, and the Shijing, or The Book of Poetry, which contains poems and songs of court and common people during the Zhou dynasty. It is likely that music played an extremely important role in the Zhou dynasty for all social classes.

One of the most important sources of information the researchers have regarding Zhou-dynasty music is from the tomb of the Marquis Yi of Zeng (433 B.C.E.). This tomb was uncovered in 1977 in Hubei Province and contained the most extensive and well-preserved set of musical instruments ever found in an ancient Chinese tomb. This four-chamber (室) tomb was designed in imitation of a palace with a central courtyard, reflecting the belief that the Marquis Yi would require the same comforts in the afterlife that he had enjoyed during his lifetime. The central chamber of the tomb, which mirrored a palace courtyard, contained most of the musical instruments found, including a complete set of sixty-five graduated bells fixed on wooden shelves. In addition, twenty-one young women were buried with the Marquis Yi, some of whom were likely his favorite musicians and dancers.

The Marquis Yi’s set of sixty-five bells is remarkable for a variety of reasons. First, they are clearly dated—an inscription (碑文) indicates that the bells were a gift given to him in 433 B.C.E.. Second, the bells were very expensive to produce and to purchase, particularly a set of this size, so they are further evidence of the Marquis Yi’s status. Finally, the bells, along with the other instruments in the room, illustrate what an instrumental band might have consisted of during this period. Scholars predict that it would have required twenty-four musicians to play all instruments at once.

There are still many gaps in our knowledge of ancient Chinese music, partly because there was no system for recording music in a written form.

6 . The researchers say they have discovered two huge magma chambers (岩浆库) under Wei Mountain in Heilongjiang. If it is true, it will be a surprising discovery since the volcano last erupted over 500,000 years ago.

Zhang Haijiang and his team visited nearly 100 sites across Wei Mountain. They were looking for magma, and they found an unusual signal from 15km underground, followed by another one at 8km. Their computer modelling suggested there could be two huge magma chambers with a depth of more than 9km. According to their research, 15 percent of the upper chamber is now filled with molten (熔化的) rock. Some studies have suggested that a volcanic eruption could take place when a chamber is filled to 40 percent magma.

They suggested that the volcanic activity in northeast China is likely to be in an active stage, and the active volcanic monitoring is needed to further understand the magma system in this area.

Xu Jiandong, director of the volcanic research, said seismic (地震的) stations had been monitoring this area for many years. "If there are really huge magma chambers in the area, we should have found some related seismic activities—When the lower chamber fills the upper one, there should be some movement," he said. "But so far, after decades of monitoring on the site, we've picked up almost nothing. The whole area has been very, very quiet," he added.

So did the researchers really find huge magma chambers? While the unusual signals found by Zhang's team looked like magma chambers, they could also have been caused by other things.

But what is for sure is that the area is active. It's like porridge boiling in a pot. But since the studies in recent years have suggested a low risk of immediate eruption in the area, the government has not set up seismic stations around. And it is certain that they aren't prepared for a big eruption over there.

7 . Considered one of the greatest archaeological finds of mankind in the 20th century, the Sanxingdui Ruins site in Sichuan province has continued to amaze the world. Since May, more than 500 cultural relics have been found at the site. 

Some of the bronze artifacts  (工艺品) discovered during the current excavation have never been seen before, according to experts. They were beyond “our previous understanding of bronze wares and posed great challenges to our research”, said Xu Feihong, a lecturer at Shanghai University.

A unique bronze artifact from the No 3 pit features a man carrying a bronze vessel known as a zun that has a round rim (边沿) and a square body, said Ran Honglin, a researcher with Sichuan Provincial Cultural Relics and Archaeology Research Institute.

Three bronze figures, with their palms pressed together and their heads twisted to the right, have been excavated from the No 4 pit.

These three bronze figures are a unique find among Sanxingdui items in terms of their shape and decorative pattern, and they provide further material for studying the bronze casting technology of the Shu people as well as their art, religious beliefs, social system and cultural exchanges with surrounding areas, Ran said. Shu was an ancient state in what is now Sichuan. 

Again, a gold mask is catching the world’s attention. 

It is the biggest of its kind unearthed at the site so far. It is 37.2 centimeters wide, 16.5 cm high and weighs about 100 grams. Another thing that makes it stand out is that it is complete. 

It was discovered in June at the No 3 pit. Earlier this year, a similar, but less complete gold mask was found at the No 5 pit.

Gold items were found at the Sanxingdui Ruins site as early as 1986, including gold foil (金箔) pieces that show how the precious metal was used by the ancient Shu people. The finding further illustrates the custom of the ancient Shu people to use gold items, experts said.

Radiocarbon dating (放射性碳年代测定) has shown that the No 3 and No 4 pits, at 3,000 to 3,200 years old, go back to the late Shang Dynasty (16th century-11th century BC), Xu said.

Excavation of the No 4 pit was completed on Aug 19, and digging at the No 3 pit will be completed in the next two months. What other treasures will the pit bring us? Only time will tell!

8 . Born into poverty on 21 May 1799, Mary Anning had to work hard from a young age. Her parents had 10 children, of whom only two survived childhood --- Mary and her elder brother Joseph. Mary’s own survival was said by her parents to be a wonder. At the age of 15 months, a sudden rainstorm hit the shelter, where Mary, her babysitter, and two children stayed. A lightning strike killed them all except Mary.

She didn’t have formal education and was only taught to read at a Sunday school. Raised in the seaside holiday village of Lyme Regis in Dorset, Mary and Joseph made a living by selling fossils to holidaymakers at their father’s waterfront booth.

Her life changed in 1811 when Joseph noticed bones mixed together with rock. Unknown to them, this was the first ever discovery of an ichthyosaurus ( 鱼 龙 ), a marine lizard from the Triassic period. Anning noted down every find she made, and after failing to find any new fossils for over a year, in 1821 she made her next discovery, digging up three more ichthyosaur skeletons. This was followed two years later by an even more impressive find --- a complete plesiosaur(蛇颈龙). This was so extraordinary that many leading scientists declared it a counterfeit, unwilling to believe that an uneducated 24-year-old could find such remarkable remains. Additionally, society at the time was highly religious and many rejected these discoveries as they conflicted with the teachings of the Bible.

Despite the setback, Anning continued to make more shocking revelations. Anning also dug up fossilized shit, which made experts know the diets of prehistoric creatures. But her biggest find of all was the first complete skeleton of a pterosaur in 1828.

All of Mary Anning’s discoveries helped influence the study of paleontology(古生物学) as scientists began to take an increased interest in fossilized animals and plants. Her work also encouraged people to question the history of the Earth in more detail and encouraged girls and those from poor backgrounds by proving that they could succeed in scientific study, a profession mainly controlled by wealthy upper-class men.
