Yunnan is the hometown of tea. It provides the ideal climate and the ecological environment for large-leaf tea trees, which are located in the     1     (region) along the Lancang River. Thousands of years ago, they formed those ancient tea plantations,     2     are the best gift that nature has grated us.

    3     (preserve) the ancient tea trees, Southwest Chinn’s Yunnan Province has passed a protection regulation recently,     4     (clarify) that wild and cultivated ten plants aged over 100 wars should be better protected in the province. The new regulation, which will come into force starting from March 1, 2023,    5    (prohibit) six kinds of behaviors that harm ancient tea plants and their growing environment. Unauthorized cutting and transplantation of ancient tea trees, carving tree branches, digging the roots,     6    damaging the ancient lea trees are all banned.

Other     7     (legal) practices include using harmful chemical herbicides, releasing waste gas and water, as well as dumping and throwing waste     8     (casual) within the protection range of the trees, according to the regulation.

Yunnan has diverse resources of tea trees. The regulation also advocates proper research and     9    (apply) of Yunnan’s resources of ancient tea trees, raising varieties     10    new tea trees of good quality, as well as the establishment of relevant industrial chains.

In southern China, there is a famous road     1    (build) across Poyang Lake, which lies in the north of Jiangxi Province, China and is known as China’s second     2     (large) lake. People in China also call it “the most beautiful road under the water.”

This road is sure     3     (attract) a lot of attention towards the end of May every year. A lot of people come out of     4     (curious). The water level of the lake is so close to the surface of the road,     5     makes the view ahead broad and bright when people drive along. It’s as though they were taking a boat across the lake. The feeling is     6     (simple) wonderful!

For the next few months, this road is not above the surface    7    under the water. When the water level of Poyang Lake starts to go up, the road surface becomes unseen. However, drivers can still drive across the lake safely     8     watching the guardrails(防撞护栏) fixed on either side of the road. For thrill-seeking motorists, it’s like     9     (drive) an amphibious(水陆两栖的) super car. Then in a few days, the entire road     10     (flood) with the continuously rising water. A few months later, the road will reappear.

There are certain things on the Earth that we must not lose. The great animal migration across the Serengeti Plains or the towering pyramids of Egypt are such examples. Every country is proud of     1     (it) cultural or natural heritage sites,     2     must be protected. We are lucky to have UNESCO to oversee such an important task. It sees heritage as our legacy from     3    past, what we live with today, and what we pass on to future generations as well as sources    4    irreplaceable inspiration.

The incredible splendour of heritage sites is a     5     (remind) of the power of nature and the genius of man. As a nature reserve, Jiuzhaigou Valley is home to snow-capped mountains, thick forests, impressive waterfalls and lakes. This dream-like scenery makes us realize that nature has    6     (true) created a masterpiece. Similarly, standing in the shadow of the Borobudur Temple, as the sun rises over this grand historic building, we    7     (impress) with the effort and determination of the people who     8    (build) it with only primitive tools.

It is in heritage sites like this     9     we cannot help but be humbled, come to understand our limitations as human beings, and know that our duty is to protect them for generations     10     (come).

Every Lunar New Year, China introduces a zodiac(生肖) sign from a cycle of 12 lucky animals. This year, it’s the Year of the Dragon, or more     1     (accurate), ”the Year of the Loong”. Then what’s the difference?

The Western     2     (describe) of dragons as “fire-breathing winged creatures” was inspired by literature such as Beowulf - the Old English epic about a Scandinavian hero     3    contribution was killing monsters, including a dragon. Greek fairy tales also presented dragons    4    violent sea monsters or guards of valuable     5     (possession). By contrast, “loong”, a word    6     (create) in the 19th century, reminds people of strength and fortune, and should    7     (distinguish) from its Western cousin. In Shiji,     8    2, 000-year-old Chinese history book, the emperor’s mother dreamed of a dragon lying on her body,     9     (predict) the birth of a future emperor. Exactly for this reason, Chinese people proudly claim they are “descendants of the Loong” .

Therefore, some culture experts have been calling for a switch to ”loong”     10     (tell) the Chinese dragon from the frightening monsters of Western tales. The call is also in line with the push for cultural confidence to choose the preferred translation of the Mandarin word for a creature long respected in Chinese culture.

Bird-watching, a hobby    1     (favor) by many westerners, has been included in a public benefit program “Park Classes” in Wuhan schools. In the past six years, the program has carried out over 3,000 activities in Wuhan’s thirty urban parks,    2    (cover) all of the city’s primary schools and welcomed by over one million students. Buried in books and having little access to the outside world, many students don’t have the     3    (little) idea of what nature really is. This program is designed to enhance the awareness of environmental protection among school kids,    4    often feel greatly refreshed by appreciating the grace of the adorable creatures through cameras.

Among the selective courses     5    (be) the restoration of small and micro wetlands .As for this course, what is needed is a lot of hands-on practice. Under the    6    (guide) of their teachers, students are required to conduct a research on a 500-square-meter wetland in the city parks. Focusing their attention    7    the wetland’s physical condition, they have recorded the number of plant and animal species to create a restoration plan. Thanks to    8    (they) efforts, the biodiversity of the wetland has been significantly improved.

“It’s very meaningful,” said Li Chenliang,    9    eighth grader from this project. “I have learned a lot of knowledge that cannot be    10    (direct) got from books. I should make full use of the city’s ecological advantages and get more chances to get closer to nature.”

The World Health Organization (WHO) has announced a shocking finding about the air we breathe. It has found that almost everyone on Earth breathes unhealthy air. The WHO made     1    (it) air quality update ahead of World Health Day on April 7. The update reported that 99 per cent of the world’s population breathes air     2     goes beyond WHO air quality limits. It looked at data from over 6,000 cities in 117 countries. People     3    (live) in lower- and middle-income countries breathe the poorest-quality air. Millions of people die in these countries because of pollution-related diseases. The WHO said: “After surviving a pandemic, it is unacceptable to still have 7 million preventable deaths due     4     air pollution.”

The WHO said its report highlighted the need to move away from fossil fuels. It asked governments to do more     5     (reduce) levels of air pollution. It said: “Current energy concerns highlight the importance of speeding up the transition to cleaner and     6    (healthy) energy systems.” It added that high gas prices, energy     7    (secure), the dangers of air pollution, and climate change mean the world must be less dependent on fossil fuels. The WHO report     8    (include) many recommendations for change. One of these is     9     use of clean energy for cooking, heating and lighting. Another is to “build safe and affordable public transport systems and pedestrian- and cycle-friendly     10    (network)”.

Mount Tai, a typical representative of the Chinese famous mountains, is a mountain with     1    long history and a special historic status. In 1982, Mount Tai was designated as the National Park of China and it     2    (list) formally in the directory of the World Natural and Cultural Heritage in 1987. It becomes a precious heritage of human beings.

Mount Tai,     3    (locate) in the east of North China Plain and the middle of Shandong Province, is known to the world for its splendid scenery. Standing out among the Shandong Hills, it is of     4    (significant) around other hills. The south of Mount Tai is     5    (high)than the north. In Mount Tai, the transportation is convenient with the Jinghu railway     6     (pass) by in the west. The distance     7     Mount Tai and Qufu City is 83.1 kilometers. Many roads and railways meet in Tai’an City,     8     just lies in the south of Mount Tai.

As a mountainous     9     (scene) spot, Mount Tai has a high value in terms of aesthetics( 美学) and science, especially the aesthetic value, which     10    (be) the foundation for Mount Tai to become a famous mountain in the history and an unparalleled heritage today.

No structure is as symbolically significant or     1     (cultural) important to China as the Great Wall. Architectural     2     (engineer)are part of a huge project to repair this centuries-old structure.

Jiankou     3     (believe) to be one of the most rugged stretches of the relic. Some of the most dangerous work includes laborers hanging from towering heights. With ropes tied around     4     (they) waists, repair workers spread cement on the wall’s steep sides, while others hold the ropes for support.     5     (survive) a fall from the steep sides would be unlikely. A laborer explains     6     he risks his life to make repairs to the ancient structure, saying that it is an honor to be part of such a great cause, and it is very     7     (meaning) to do so.

Getting supplies to this part of the wall is also a demanding effort. Because the path is so steep, donkeys and mules must be used to transport bricks,     8     can weigh as much as 150 kg each. The repair team goes to great lengths     9     (keep) the principle of minimal intervention. “We have to stick     10     the original format, the original material and the original craftsmanship, so that we can better preserve the historical and cultural values, ” said Cheng Yongmao, the engineer leading Jiankou’s restoration work.

For protecting endangered neighbors, pandas make unreliable umbrellas.

Like many undergraduate biology students, Wang Fang was taught that pandas are a prime example of     1     umbrella species—a well-known and usually endangered animal     2     protection benefits an entire ecosystem.

In fact, the story is much     3     (complex), according to findings that Dr. Wang, now an ecologist at Fudan University in Shanghai, published last month in Biological Conservation. Refuting (反驳) years of     4     (assume) about the universal benefits of panda conservation, Dr. Wang and his colleagues report that a number of other     5     (threaten) species are not being protected by the panda umbrella.

Panda conservation, on its own,     6     (be) a success up to now. In the 1980s, pandas had very little protection in the wild and were thought to add up to around just 1,100 individuals. In the 1990s, China began to     7     (active) conserve wild populations. Eventually sixty-seven panda-specific protected areas     8     (represent) 70 percent of the species’ range were established.

All of those efforts focused simply not on other species,     9     on China’s national animal. Dr. Wang began to question the umbrella species narrative and carried out research, only     10     (find) that panda conservation had not helped large carnivores in China.
