Imagine mountains wrapped in silver water,     1     (shine) in the spring sun. Summer     2     (see) the mountain s turn bright green with growing rice. During autumn, these same mountains are gold, and in winter they are covered in     3     (sheet) of white frost. These are the colours of the Longji Rice Terraces.

These terraces were built by the local Zhuang and Yao people,     4     whom Guangxi is home.     5     (start) in the Yuan Dynasty, work on the terraces took hundreds of years, until its     6     (complete) in the early Qing Dynasty. Reaching as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top.

So why did these people go to so much trouble to turn the entire mountains     7     terraces? Firstly, there are few large, flat areas of land in the region.     8     (build) the terraces therefore meant that they could increase the areas in     9     they could grow rice. Secondly, although the region has plenty of rain, the mountains are steep and the soil is shallow. The flat terraces catch the rainwater and prevent the soil from     10     (be) washed away.

Peru is a country on the Pacific coast of South America,    1    includes three main areas: narrow, dry, flat land    2    (run) along the coast, the Andes Mountains, and the Amazon rainforest. In the high plain area is Lake Titicaca, the highest lake in the world, on which boats can travel. Peru has abundant plants from desert grasses    3    vast areas of jungle.

Peru    4    (take) control of by Spain in the 16th century until 1821. So Spanish is    5    (official) spoken in Peru. The ancient Inca capital, Cusco, is a popular destination for the    6    (tour) as it is close to the famous Inca ruins of the city of Machu Picchu.

There are two especially interesting things    7    (admire) about the Inca civilization. The first is the roads and paths they built to connect    8    (they) important cities. Second, the Inca built wonderful cities,    9    there were no markets in these cities. One of the interesting    10    (question) of history is how the Inca lived without shopping.

At Zhongshuge, a bookstore and library in Yangzhou，China, the books go on forever, or at least, that's    1    it looks like. When you walk into Zhongshuge，you're surrounded on all sides by endless books. They fill the ceiling, walls, and floor，some even    2    (appear) to be challenging gravity.

How does this magical bookshop do it?    3    arehitectural studio called X+ Living designed the internal structure of Zhongshuge. The shelves    4    (arrange) in are shapes，creating the tunnel-like appearance. The floor is covered with black mirrors, reflecting the shelves above and creating the visual effect that the bookshelves continue down past the floor on    5    you're standing. And there you have it：the rows of books never end.

As it turns out, the store's design has more    6    (significant) than just fun. Yangzhou is full    7    canals and rivers，and in history many of China's literary greats    8    (draw) inspiration from the flowing water. X + Living, therefore, integrated this concept with Zhongshuge, and tried to create the feel of being    9    (complete) involved in a “river“ of books. They highlighted that feeling with the zigzag shape on the ceiling, which,    10    (reflect) on the floor, “flows“ throughout the store like a river.

    1     (locate) in the north-east of Italy, Venice is known as “The Floating City”. It is made up of over 100 small islands, which are connected by waterways and bridges.     2     (fortunate), water is also putting Venice in great danger. Saltwater is slowly damaging the bases of Venice’s buildings. The Floating City is, in fact, sinking.

More problems are caused by floods,     3     usually hit the city each winter. But these floods could now be a thing of the past thanks to a new flood     4     (prevent) project. Venice lies in     5     middle of a lagoon, and rain and strong winds cause seawater to travel through the natural gaps to Venice. Dozens of gates     6     (build) to hold back the sea until now. Each of these gates is 20 meters wide,     7     the longest about 30 meters long. In the event of a big rise in the water level, the gates will be raised     8     (separate) the city from the sea.

But only time will tell     9     this project is the right solution. The important thing is that action is being taken to protect this unique city for future generations. And if it works, it means a longer,     10     (dry) future for Venice.

China’s Liangzhu Archaeological Site     1    (declare) on the list of World Heritage sites on Saturday by UNESCO’s World Heritage Committee during its 43^rd session in Baku, the capital of Azerbaijan.

The site,     2    is located in Yuhang District in Hangzhou City in China’s eastern Zhejiang Province, showcases the civilization of prehistoric rice agriculture between 3,300 B.C.     3     2,300 B.C. The ruins of ancient Liangzhu city were discovered in 2007, and then large dam sites     4    (surround) the Liangzhu ancient city were unearthed continuously after 2009. It was     5     (official) submitted to UNESCO in 2019, hoping to win     6     (recognize) as a World Cultural Heritage Site. The site     7     (include) archaeological remains and unearthed cultural relics of the Liangzhu Ancient City as well as a wetland that covers     8     area of 908. 89 hectares in a plain river network. It is also found that the Liangzhu ancestors started to use characters about 5 ,000 years ago, 1 ,000 years     9     (early) than previously thought, according to Colin Renfrew, a retired professor of archaeology at the University of Cambridge.

The World Heritage Committee added Liangzhu to the UNESCO list    10     (encourage) better protection of the site, considered to be of “outstanding universal value” to humanity.
