China is the world’s largest tea producer, exporter, and consumer. In 2022, China produced 3.35 million metric tons of tea,     1     (account) for nearly half of the global tea production.

At present, however, the digitalization is     2     the tea industry needs most. “With the development of economy, the tea production area in China     3     (experience) fast development but faces challenges such as old-fashioned production and management methods,” said Jiang Renhua,     4     tea expert, at the opening ceremony of the 32nd China Tea Science and Technology Annual Conference in Qingdao.

    5    (address) the industry’s challenges, Jiang suggested a comprehensive (全面的) digital transformation that covers every aspect of the tea production chain, from picking     6     processing and sales. The concept of intelligent tea gardens     7     (be) a notable example. With the help of modern technologies, tea growers can monitor the growth of tea trees and their surroundings more precisely (准确地).

In spite of the significant progress     8     (achieve) in monitoring methods, challenges remain. High-performance sensors that can     9     (accurate) detect the soil are in high demand but still limited in availability. Research and development efforts, as well as the installation (安装) of such sensors, face challenges due to the diverse soil     10     (condition) in tea-growing areas.

China is known as a state of etiquette (礼仪) and ceremonies. Take the example of an interesting story. Once upon a time, a man went on a long tour     1     (visit) his friend with a swan as a gift. But it escaped from the cage on the way and in his effort to catch it, he caught nothing but a feather. When his friend received this unexpected gift—the swan feather, he was     2     (deep) moved by the sincerity (真诚). Later, the saying “the gift is nothing much, but it is the thought     3     counts,” was spread far and wide.

Gifts are regarded as an important part to show politeness in China.     4     is appropriate to give gifts on     5     (occasion) such as festivals and birthdays. If you are invited     6     a family party, small gifts like wine, tea or candies are welcomed. Also fruit, cookies, and flowers are a safe     7     (choose).

Chinese used to cup one hand in the other before the chest as a salute (致敬). This tradition, nowadays seldom     8     (follow) except in the Spring Festival, has a history of more than 2000 years. Shaking hands, which should be firm and brief but not too strong,     9     (consider) formal greeting behavior in China.

If you follow the usual rules of etiquette in China, there is no need to worry about the cultural barriers, for the warm and friendly Chinese will try their best to respect your customs when     10     (communicate).

China will pool efforts to promote the high-quality development of museums with the aim to build     1    (it) into a country with top-level museums by 2035, a guideline issued on Monday noted.

According to the guideline,     2    (prepare) by nine departments including the National Cultural Heritage Administration, China     3    (plan)to upgrade 10 to 15 museums into world-class ones with Chinese     4    (feature). The country will help foster the     5    (grow) of medium- and small-sized museums and strengthen their innovation mechanisms, the guideline said.

It added China will also expand museum collections and encourage the public     6    (donate)pieces.

By the end of 2020, China was home     7     5,788 museums    8    had been registered with authorities, with 1,224 museums at the state level.

    9     average of one new museum     10    (open)every two days across China between 2016 and 2020.

This scene at the opening ceremony of the Beijing 2022 Winter Olympics amazed the world. Fireworks     1     the shape of the “Guest-Greeting Pine“ made the world feel the enthusiasm of an open China. The “Guest-Greeting Pine”, named after its shape like a person    2    (wave) to welcome visitors, is one of the landmarks on Mount Huangshan, which     3    (sit) in the south of Anhui Province.

As a UNESCO natural and cultural heritage site, Mount Huangshan is also a global geopark characterized by a Mesozoic granite landscape. This     4    (drama) landscape includes formations of natural stone pillars, strangely-shaped rocks, waterfalls, caves, lakes and hot springs, formed by    5    (it) complex geological history. Its magnificent natural scenery of massive granitic stones and ancient pine trees is often    6    (far) enhanced by cloud and mist effects.

Mount Huangshan boasts 72 peaks, among    7     Lianhua Peak, Guangmingding Peak and Tiandu Peak are the three main peaks, with    8     altitude(海拔) of over 1, 800 meters. In Mount Huangshan, there are more than 200 cloudy days in a year. When the water vapor rises or the fog does not disappear after the rain, it     9    (form) a sea of clouds, presenting a fairyland landscape.

As a famous traditional mountain in China, Mount Huangshan bears profound historical and cultural     10    (mean) with ancient buildings, ancient pedals, cliff stone carvings, etc. , and has bred the “Huangshan Painting School” of Chinese landscape painting.

Food from the air

Everyone has seen plants growing, but have you ever thought     1     they get their food? In the seventeenth century, a European scientist     2     (call) Van Helmot asked this question. Like most people, he thought that plants must get their food from soil. However, Van Helmot decided       3     (test) the theory with experiments.

First, he dried some soil, put it into a pot and weighed it. Next, he weighed a small tree, planted it in the pot and added rain water. Then, he watered it     4     (regular) with rain water.

After five years, he removed the tree from the pot and weighed it again. He found that the tree had gained     5     huge amount of weight. When he weighed the soil, however, it was almost exactly the same as it had been five years    6    . So Van Helmot drew the    7    (conclude) that the tree grew by drinking water. Though it turned out to be wrong, he showed the importance of the use of scientific evidence to support ideas.

We now know that plants and trees make their own food. Their leaves, when exposed     8     the air and sun, are like factories    9     can change the energy from the sun into chemical energy. During this process (过程), oxygen and sugar     10     (produce). The oxygen is released back into the air, and the sugar is used by the plant as food.
