Yungang Grottoes(石窟) in Datong, Shanxi Province, are a world cultural heritage site with a history     1     goes back more than 1, 500 years. In Yungang’s 45 big grottoes and more than 200 small grottoes,     2     (rough) 59, 000 figures of the Buddha are a priceless treasure of human culture.

But because of the effects of climate change and natural disasters,     3     grottoes face damage year after year. Thanks to     4     (advance) digital technology, researchers are busy “duplicating” the Yungang Grottoes in an attempt     5     (preserve) the precious cultural relics. Employing 3D laser scanning technology, the researchers digitally record the shapes, colors and other fine details of the grottoes and later reproduce them by     6     (use) 3D printing technology.

The new technology could     7     (able) more people to have access to the cultural relics despite the distance. In June, 2020, the Zhejiang University Cultural Relics Research Institute and Yungang Grottoes Research Institute together copied and pasted Cave No.12 of the Yungang Grottoes for the     8     (exhibit) in Hangzhou. There, people could see the world’s first 3D-printed 1:1 copy of a grotto.

The Yungang researchers’ attempt is a good example of technology helping to preserve cultural heritage. It     9     (hope) that the new digitized technologies will facilitate the “rebirth” of the cultural relics, and bring them     10     more places worldwide.

The Grand Canal is the     1     (long) and oldest canal in the world. It forms a vast inland waterway system in China, running from the capital Beijing in the north     2     the Zhejiang Province in the south.

Constructed in sections from the 5th century BC and completed and     3     (maintain) by several dynasties, it formed the backbone of China’s inland communications system,     4     enabled the supply of rice to feed the population. The Grand Canal     5     (reach) a new peak in the 13th century, providing an inland shipping network consisting of more than 2,000 km of artificial     6     (waterway), which linked five of the most important river basins in China, including the Huanghe River and the Changjiang River. Still the major means of internal communication today, it has played an important role in ensuring     7     prosperity (繁荣)and stability of China over the ages.

The Grand Canal is an essential technological achievement     8     (date) from before the Industrial Revolution. It     9     (be) a perfect example of dealing with difficult natural conditions, as is reflected in the many constructions that are     10     (full) adapted to the diversity and complexity of circumstances. It best demonstrates the technical capabilities of Eastern civilizations.

Hangzhou is recognized as the “City of Well-Being” in China. Hangzhou made its name    1    (know) to the world in 2016 by hosting the G20 Summit. Blessed with pleasant climate and few wars, Hangzhou has gradually formed    2    (it) own urban character.Unlike busy Shanghai, you will slow down and relax once you are here. It seems that Hangzhou people don’t have many things to rush to in their    3    (day) life. No wonder Hangzhou is expanding    4    (annual) by 500, 000 to 600, 000 people.

The lifestyle, however, was laid down by two historical men of letters. One was Bai Juyi,     5    rebuilt the West Lake and made a new bank    6    (benefit) the locals. People love him. When it comes     7     him, it doesn’t sound like one is talking about a person who    8    (live) a thousand years ago. The other was Su Shi. His open-minded personality    9    diligence for his people left many much-told tales. Seemingly,     10    (mention) his name gives people joy even after a thousand years.

Surely, it will be even more brilliant in 2023 when it hosts the 19th Asian Games. Let’s look forward to it.

During the last Spring Festival, thousands of people     1     (attract) to a 2-meter-wide lane in Tong-cheng, Anhui Province. Although it was impossible to count the exact number, at least 5, 000 people visited it each day. This narrow lane,     2     (call) Liu chi Lane in Chinese, won greater     3     (popular) after the story behind it was broadcast on a CCTV show. At first glance it may seem unimportant,     4     to those who know its history, Liu chi Lane means much more than its appearance. In the early Qing Dynasty it     5     (serve) as the boundary between Zhang family and Wu family. They quarreled     6     (fierce) over which family had the right to build a wall on the dividing line. After failing     7    (make) a compromise, the Zhangs turned to Zhang Ying,     8     family member of Zhangs and also a top official in the emperor’s court. To     9     (they) surprise, Zhang Ying did not provide the support they needed. He called for his family to step back one meter from the boundary. Seeing that, the Wus agreed to move back another meter. Thus Liu chi Lane was born. The story of Liu chi Lane tells people how to get along     10     others.
