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.

Hua Weiguang,     1     retired teacher from Tongliao, Inner Mongolia Autonomous Region, is a photography enthusiast.

A decade ago, the arrival of tree planters     2     (catch) Hua’s attention and the photos of the tree planters     3     (take) by Hua are evidence of the     4     (remark) transformation of the land. In those photos, hats, scarves and goggles, for the workers fighting desertification, are basic necessities to protect them     5     the wind and sand. There was no way to avoid the brutal summer heat in the land so the workers had to lie down on the ground or curl up in the narrow shade of their cars to cool off. And they also had to eat their lunch amid the blowing sands, taking in the small pieces of sand with their food.

“    6     we don’t fool the tree, it won’t fool you. You take it     7     (serious), and then it behaves in the same way to you. You put efforts to make it live, and the tree lives up to your     8     (expect),” the planters say.

China’s forest resources have increased by over 70 million hectares in the past decade,     9     (rank) first in the world. One tree after another, a green Great Wall has been built. Brush by brush, a green field     10     (paint) over the yellow sandy land up to now.

Giant Amazonian lily pads(睡莲叶) are the world’s largest and strongest floating plants and the giant Amazonian water lily has long fascinated scientists, architects and artists for    1    (it) beauty and sheer size. Yet how the lily’s leaves are able to grow as large as 10 feet across, strong enough to support the    2    (weigh) of a small child,    3    (remain) a mystery—till now. “    4    we showed through our experiments and modeling was that these leaves are uniquely strong and have great opportunities    5    (enable) them to grow really big,” says Thorogood, from a team of British and French scientists. In fact, the giant lily    6    (discover) by British explorers in South America in 1801 and symbolized the British Empire. But it became more than    7    symbol as botanists repeatedly attempted to grow it at home. The British gardener and architect Joseph Paxton was the first to    8     (success) grow the giant water lily. It inspired his design of the Crystal Palace, a London landmark of cast iron and glass that was built for the Great Exhibition of 1851. “Nature was the engineer,” Paxton said. “Nature has provided the leaf    9    special structures and supports that I,    10    (borrow) from it, have adopted in this building.”
