The Great Wall of China with a total length of over 5,000 kilometers is one of the greatest     1     (wonder) of the world. The Great Wall starts from Jiayuguan in Gansu Province in west China and     2     (end) at Hushan Mountain in Liaoning Province in     3     east. The Great Wall stretches from west to east like a giant loong,     4     (wind) its way across mountains, through deserts and over valleys. It was built continuously over more than 2,000 years originally     5     (protect) the northern borders of the Chinese Empire against intrusions by     6     (vary) nomadic(游牧的)groups. One of the most famous is the wall     7     was built between 220-206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains, and the majority of the existing wall     8     (build) during the Ming Dynasty.

The Great Wall is not only a brick wall, but also one of the world’s greatest historical architectural works. It played a significant role     9     Chinese history. The Great Wall has been a symbol of Chinese civilization,     10     it has become one of the most famous scenic spots in China, attracting tourists from all over the world.

Later, the Ming Dynasty     1     developed relations with these regions. Between 1405 and 1433, seven large fleets sailed west on voyages of trade and exploration. These fleets were a sight to behold and were in a     2     of their own at that time. …African     3     families sent gifts such as giraffes as gestures of friendship in return for gold, silk, and spices. Although China     4     from further expeditions after 1433, these land and sea routes remained active     5     between other, cultures for centuries.

To write his own medical text, Li Shizhen referenced over 800 medical texts, countless books on history and geography, and works of literature. He even studied the complete works of many ancient poets, from     1     he selected a surprising number of verses about medicine. However, the greatest issue he encountered was the widespread     2    (inconsistent) in the use of drug names. Realising the importance of field research outweighed     3    of extensive reading, in 1565 Li travelled far and wide into the mountains and wilderness. He covered what are today’s provinces of Hunan, Jiangxi, Anhui and Jiangsu, and many other places.

After over a decade of field research, Li     4    (successful) completed the first draft of his masterpiece, Bencao Gangmu, or the Compendium of Materia Medica in 1578. He revised     5     work at least three times right up until his death in 1593.

Since its first publication in 1596, the book     6    (receive) world-wide recognition. British naturalist Charles Darwin acknowledged the book     7     an “ancient Chinese encyclopedia.” In 2011, the book    8    (list) on the UNESCO Memory of the World Register. In 2017, an international conference was held in Beijing     9    (celebrate) Li’s 500th birthday.

Today, there are a     10    (grow) number of international exchanges centering on Li Shizhen and his book, and many people around the world can still find the wisdom of human development in this ancient classic.

9 . Up to one quarter of the world’s population use chopsticks as their main eating tool. Called kuaizi in Chinese, chopsticks were developed in China about 5,000 years ago. Often made of wood, chopsticks allow users to pickup pieces of food by holding together and releasing (松开) the sticks with the thumb (拇指) and first three fingers.

Before the invention of chopsticks, the Chinese used only their hands to eat. One reason why chopsticks were invented is that eating with one’s hands allowed some people to take more food than others. This was considered rude, so using chopsticks, which limited the amount of food that could be taken at one time, was thought to be a more polite practice. Another one was about the great Chinese philosopher Confucius, who was a vegetarian. He objected to the use of knives at the table, feeling that they reminded eaters of the slaughterhouse (屠宰场), so he preferred chopsticks.

At first, chopsticks were used only by nobles (贵族). Later on, during the Western Han Dynasty, which began in 202 BC, commoners (平民) began to use chopsticks as well. At that time, people used chopsticks only to eat side dishes; spoons were used for rice and for soups. During the Northern Song Dynasty, which lasted from AD 960 to 1127, noodles became a popular dish. It is very diffcult to eat noodles with a spoon, so chopsticks were used more often. Today, chopsticks are the main eating tool in China, Japan, and Vietnam; and people from countries all over the world commonly use this tool while eating Asian dishes.

10 . 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.
