Located at the western part of Hangzhou, just under 5km away from the West Lake, Xixi National Wetland Park distinguishes itself as     1     exceptional urban place. This park is a pioneering example of how urban life combines agriculture with culture, making it a     2     (real) unique destination. Along with Xihu and Xiling famous, respectively, for their natural scenery    3     cultural heritage, Xixi National Wetland Park is one of the celebrated “Three Xi’s of Hangzhou”.

    4    (cover) a vast area, the park consists of three causeways(堤道) and features ten famous sights. Nearly 70% of the park is occupied by river ports, ponds and small lakes,     5     explains a wetland environment. These waterways cross the park, dividing it into distinct     6     (section): the east, the west, and the central part.

So far, the government     7     (establish) ecological protection zones as well as a sightseeing zone.     8     addition, visitors can explore the Wetland Science Exhibition Hall at the park’s main entrance conveniently.

The Xixi wetlands is an area of unmatched peace and quiet — filled with history and natural     9     (beautiful). The only true thing that can be said of the Xixi wetlands     10     (be) that if you haven’t seen them, you haven’t really seen Hangzhou.

Twin giant pandas have been born at a breeding (繁殖) center in southwestern China,    1    is a sign of progress for the endangered species as they struggle for survival due to occupation on their land by agriculture    2    industry.

The male and female baby pandas, born on Tuesday at the Qinling Panda Research Center in Shaanxi Province, are the second pair of twins born to    3     (they) mother, Qin Qin. She was also born at the center and    4     (previous) gave birth to twin females in 2020.

Chinese researchers for years have been working    5     (promote) the population of the animals, which reproduce rarely in the wild and rely    6    a diet of bamboo in the    7     (mountain) of southwestern China.

The efforts have paid off, with some captive-bred pandas being released into the wild. The population of wild pandas    8     (increase) over the past few years,    9     (reach) an estimated 1,800. About 500 others live in zoos and reserves, while the    10     (major) live in the mountainous, heavily forested province of Sichuan.

On February 16, 1861, a big earthquake struck Sumatra, an Indonesian island. The earthquake shook the western side of the island,     1     (cause ) a tsunami. That wall of water poured onto shore, destroying towns and taking thousands of    2     (life) .

Recently, though, a team of scientists discovered that another earthquake occurred before this deadly event. According to the record, that earthquake     3     (start) in 1829 and lasted for 32 years but no one felt even one shake. This kind of slow-moving earthquake    4     (call) “silent earthquakes” because no instrument can find them. Scientists have only begun discovering them because    5     the advances in GPS technology in the last twenty years.

    6     (find) out what is going on under the ground, scientists need to study earthquakes. Every earthquake, either small     7     big, can teach scientists something about how much the ground will shake in the future. Unluckily, no one can predict (预测) when an earthquake will hit. Scientists just have to prepare to study all earthquakes    8     hit.

But silent earthquakes like the one in Sumatra change the game for scientists. These silent earthquakes happen all over    9     world. Sometimes, a silent earthquake happens just before a regular one, both of which might be related. By studying silent earthquakes, scientists hope to better understand regular earthquakes and    10    (possible) predict them.

I was one of the people     1     work on Qinghai-Tibet Railway, which was completed by overcoming the most difficult engineering challenges to protect the delicate ecosystem.     2    (allow) animals to move safely and freely, thirty-three     3    (passage) have been built. To prevent damage to wetlands and grasslands, 675 bridges, which is about 160 kilometers in     4    (long), were built and 140,000 square meters of wetlands     5    (move) to protect its distinct ecosystem. Tanggula Station, which     6    (locate) at over 5,000 meters above sea level, is the highest railway station in the world. To keep us     7    (health), several oxygen-making stations were constructed. To protect Cuona Lake     8     construction waste, a twenty-kilometre wall was built. Thanks to     9     efforts, passengers, who have been attracted by the Qinghai-Tibet Plateau, have been enjoying these     10    (impress) landscape.

Peru     1     (lie) on the Pacific coast of South America with three main     2     (area): the land running along the coast, the Andes Mountains, and the Amazon rainforest. In the 1400s and 1500s, Peru was the centre of the     3     (power) ancient Inca Empire, whose emperor lived in the site Machu Picchu. In the 16th century, Spain took control     4     Peru. In Amazon Rainforest, you take     5     boat to reach your accommodation. Three days will witness the unique plants and animals there.     6     (walk) on the path through the Andes Mountains leads to Machu Picchu. You’ll     7     (amaze) by this destination.     8     (especial) amazing is the Incas’ dry stone method of building. Stones are cut in exact sizes     9     (hold) walls together other than the perfect fit. In Cusco, you must admire architecture. In Lake Titicaca, both the island     10     the local homes are made of water plants from the lake.

China has the world’s largest number of world natural heritage (遗产) sites. The country is now home     1     14 world natural heritage sites and four mixed sites,     2     are famous for both cultural and natural features, both leading the world in terms of quantity, the administration said. These heritage sites     3     (effective) protected China’s representative geological relics, mountains, forests and lakes, along with the rare and     4     (endanger) animal and plant species, the administration said Friday at     5     news meeting about cultural and natural heritage day, which falls on June 8 every year. In the past few years, the country     6     (increase) legal, and technological support of the protection of its world natural heritage, establishing a     7     (manage) system with Chinese characteristics. China’s world heritage has contributed to the country’ economic development     8     presented its image to the world. These areas have also played an important role in the protection of cultural relics, intangible cultural heritage and historic cities, towns and villages,     9     (bring) in over 14 billion yuan in average annual tourism income for     10     (local).
