Every weekend, many bookworms gather in Liyuan Library in Jiaojiehe village, a book sanctuary surrounded by chestnut, walnut and peach trees     1     branches are used to decorate the building.

Deep in the heart of a rocky valley on the outskirts of Beijing, the wooden library sits seemingly in    2    middle of nowhere. It     3    (design) about 11 years ago by Professor Li Xiaodong, from the School of Architecture at Tsinghua University. Decorated with 40,000 firewood sticks outside, the bookstore features 10, 000 books    4    (range) from literature to history.

The library, which opened in 2012, draws     5    (hundred) of visitors every weekend, many of whom are attracted by the design. The main framework of the bookstore is made of steel bars and the outside wall and     6    (it) roof, glass. With space for just 40 people     7     a time, visitors line up       8    (enter) the library, which only opens on weekends. Bookshelves line the reading area, as readers stand or sit on the floor and platforms.

“We have now     9    (strict) banned taking pictures inside, as some people come here just to take pictures. They even come in costumes, and that’s really disturbing,” owner Pan Xi complained. “We still want to give those who really love reading a quiet and     10    (peace) environment. ”

Libraries have been treasures of knowledge for millennia, and during the ages, little has changed in     1     they operate on a basic level.

Only in the past few decades have computer databases made logging books and academic     2     (paper) more efficient. Artificial intelligence (AI) has meant that library chatbots can answer questions for visitors     3     (look) for new books and direct them to the appropriate resources.     4     (typical), automated (自动化) conversations between users and machines can enable librarians     5    (focus) on more complex questions about books that require nuance (细微差别), and it can save     6     (they) from repeating the same answers again and again.

Library open hours could also be extended as a result of having such a consistent and open     7     (serve). Machine learning programs mean other complex library tasks,     8     require an understanding of the literature, can be further automated. In the sea of information, books require the content summary that     9     (preserve) key elements of the meaning from original texts for potential readers. AI tools are now capable of such an automatic summary, meaning a chapter can be broken down     10     just three sentences.

Chinese scientists have started a scientific expedition to the Mount Qomolangma.     1     total of 170 scientists have begun to do research on water, ecology and human activity, aiming     2     (reveal) the mechanism of environmental change and optimize the ecological security barrier system on the Qinghai-Tibet Plateau.

    3     (label) as the roof of the world and water tower of Asia, the Qinghai-Tibet Plateau is an essential ecological security barrier in China. It is also a natural laboratory for     4     (conduct) research on the evolution of Earth and life, and the relationship between man and Earth.     5     an important part of the research, the ongoing expedition is     6     (particular) important to the study of the impact of climatic and environmental changes in the Mount Qomolangma region on other parts of the world.

The expedition focuses on major scientific     7     (issue), such as how the extreme high-altitude environment of the Mount Qomolangma changes under the influence of global warming, according to Yao Tandong,     8     is the team leader. “The expedition has realized the     9     (transform) from ‘I want to conquer you’ to ‘I want to understand you’, achieved the application of new technologies and resulted in important international influence,” he said. So far, many scientific achievements     10     (make).
