Chinese archaeologists announced Saturday    1    new major discovery has been made at the legendary Sanxingdui Ruins Site. This site    2    archaeologists recently have found six new sacrificial pits (祭祀坑) and unearthed (出土) more than 500 items    3    (date) back to 3,000 years ago lies in Sichuan Province and was first found in 1929. So far,    4    (vary) cultural items    5    (unearth) from four of the pits, including pieces of gold masks, gold foil, bronze masks, bronze trees, ivory and jade. The rest of the    6    (new) discovered pits are still under excavation(开发).

Covering 12 square km, the relics site,    7    (locate) in the city of Guanghan, about 60 km from Chengdu, is believed to be the remnants of the Shu Kingdom. In the process of excavation, archaeologists made full use    8    modern technologies    9    (ensure) the safety of the relics and sound management of relevant data and material. The project featured scientific cooperation and a    10    (combine) of archaeology with conservation and research.

4 . Bears do it. Bats do it. Even European hedgehogs do it. And now it turns out that early human beings may also have been at it. They hibernated - slept through winter, according to fossil experts.

Evidence from the bones found at one of the world's most important fossil sites suggests that our primitive ancestors may have dealt with extreme cold hundreds of thousands of years ago by hibernating.

The conclusion is based on excavations in a cave called Sima de los Hueso—the pit(坑) of bones—at Atapuerca, in northern Spain. The fossils date back more than 400,000 years and were probably from early Neanderthals or their ancestors.

In a paper published in the journal L'Anthropologie, Juan-Luis Arsuaga and Antonis Bartsiokas argue that the fossils found there show seasonal variations that suggest that bone growth was interrupted for several months of each year.

The pattern of lesions(病变) found in the human bones at the Sima cave are consistent with that found in bones of hibernating mammals, including cave bears. "A strategy of hibernation would have been the only solution for them to survive having to spend months in a cave due to the chilly conditions," the authors state.

They examine several opposite arguments. Modern Inuit and Sami people—although living in equally harsh, cold conditions—do not hibernate. So why did the people in the Sima cave do it?

The answer, say Arsuaga and Bartsiokas, is that fatty fish and reindeer fat provide Inuit and Sami people with food during winter and so preclude the need for them to hibernate. In contrast, the area around the Sima site half a million years ago would not have provided anything like enough food.

The Han Dynasty ruled China from 206 B.C. to 220 A.D. It is known for     1     (it) promotion of Confucianism (儒学) as the state religion and opening the Silk Road trade route to Europe, permanently     2     (change) the course of Chinese history. The Han Dynasty art and inventions like paper still influence the world today.

Most knowledge of the Han Dynasty art comes from the tombs of ruling families. The Wu Family site in Jiaxiang is one of the most famous. The tomb features 70 carved stones and     3     (paint) ceilings and walls and various pictures     4     describe historical characters. The site contained about 3000 examples of Han Dynasty art     5     (figure), using silver, bronze, gold etc. Two suits with 2000 pieces of jade (玉) in each     6     (discover) in the tomb. The tomb survived well because the outside areas were not decorated     7     any special way, but marked only by a large pile of dirt.

Paper was invented in China during the Han Dynasty. The paper-making technique was developed by Cai Lun,     8     officer attached to the Imperial court, and he made paper a     9     (common) used writing material. Paper-making technology has promoted the spread of human culture and is a great     10     (contribute) of the Chinese nation to the world civilization.

The site of Sanxingdui is recognized as one of the most important ancient ruins    1    (date) back 4,800 years. Chinese archaeologists launched a second excavation in March after 35 years, which has brought    2    (grow) interest to this ancient land．

Travelers from across the country    3    (come) to get a glimpse of the prehistorical mysteries on the first day of China's five-day Labor Day holiday this year. The museum,    4    (situate) in the northeast of the Sanxingdui site, looks to make the tour more    5    (enjoy) by rolling out over 300 different types of cultural and    6    (create) products. Unearthed from Sanxingdui’s No.2 pit, the ivory beads are    7    the shape of a long drum, painted with black circles.

Ivory was    8    symbol of wealth in ancient China. Jewellery made from ivory     9    (belong) to the noble class and were    10    (most) placed in bronze vessels as offerings to the gods．

Since Chinese archaeologists(考古学家)     1    (make) public some of the newly unearthed artifacts from the Sanxingdui Ruins site on Saturday, a gold mask has caught most of the attention from experts and     2     public alike.

Recognized as one of the most important ancient     3    (remain) found in the 20^th century, the 3000-year-old Sanxingdui in southwest China’s Sichuan province is a treasure house     4    (bury) with a collection of pottery, jade, bronze and gold wares.     5     astonished the archaeologists most about this gold mask is its large size. 23 centimeters wide and 28 centimeters high. Although only about half of the gold mask was unearthed, it’s so far the     6    (large) of its kind found in the primary stage of the Chinese civilization, weighing 280 grams.

It     7    (estimate) that the whole mask could weigh more than 500 grams. This lightweight mask is made of gold foil(箔), featuring a raised nose with a sharp edge at the tip. It’s     8    (basic) the same size as the head sculptures from the same pit. Thus, archaeologists believe it was originally attached     9     the face of a head sculpture.

The masks’ eyes and eyebrows are delicately hollowed out,     10    (create) a sense of seriousness and dignity. They most likely represent authorities or top-level figures at that period, according to archaeologists.

The     1    (remain) of a gold mask are among a huge cache of 3, 000-year-old artifacts found at an archaeological site in China's Sichuan province. Weighing about 280 grams and estimated to be made from 84% gold, the ceremonial mask is one of over 500 items     2    (unearth) from six newly discovered "sacrificial pits," according to official sources. The finds were made at Sanxingdui, a 4. 6-square-mile area outside the provincial capital of Chengdu. Some experts say the items may shine     3    (far) light on the ancient Shu state, a kingdom     4     ruled in the western Sichuan basin until it was conquered in 316 B. C..
