For those consuming Asian food, using chopsticks is almost second nature. About 20 to 33 percent of people in the world use chopsticks     1    a daily basis. Not all of those are disposable (一次性的),     2    no doubt many are.

Felix Bock, a student at the University of British Columbia, was eager to find a way     3     (recycle) wood from construction projects, and he had a particular interest in bamboo. One day he noticed a drawer in his friend’s house filled with disposable bamboo chopsticks, and an idea hit     4    .

He decided to give     5    second life to disposable chopsticks by making them into home     6    (decoration) or other accessories (配件). He told the idea to restaurant owners,     7    (convince) them to install recycling bins in their restaurants. He cleaned the chopsticks, pressed them into square pieces and coated them with glue. The square pieces were then     8     (creative) arranged into household and office products. Bock’s company, called Chop Value, has repurposed chopsticks into desktops, cutting boards and even table games.

Since 2016 when the company     9    (found), Chop Value has rescued billions of chopsticks from landfills. Instead of an economy of the typical take-make-dispose model, Chop Value seeks to create one     10    transforms waste into a usable resource.

Rising sea levels are threatening coastlines in China, for example in     1    (city) such as Shanghai, Tianjin and Guangzhou.     2     sea levels rise by one meter, more than 92,000 square kilometers of China’s coast could be flooded. This could possibly force 67 million people     3    (move) away. Almost two-thirds of the ice in Asia’s glaciers (冰川) could disappear if average global temperature rises beyond 1.5℃ by the end of the century. If that happens, the impacts     4     China will be felt in many areas, from water availability, to agriculture, and to biological surroundings. The good news is     5     China is becoming a global leader on climate action. For example, over the last five years, China     6    (use) more solar and wind energy than any other country in the world. China is also the     7    (large) clean energy investor in the world — spending $130 billion in new energy in recent years. The development of electric vehicles is particularly inspiring in China. More than 50 percent of electric vehicles in the world     8    (sell) in China every year. And China is now a world leader in the     9    (develop) of clean energy technologies. Ecological civilization has become the cornerstone (基石) of China’s long-term development strategy, much like climate action is     10     important part of the 17 Sustainable Development Goals.

Situated on the outskirts of Hangzhou in East China’s Zhejiang province, Xixi National Wetland Park is the first national wetland park in China. For the abundant ecological    1    (resource), natural unaffected scenery and deep cultural influence here, it is the only natural wetland park combining agricultural wetland    2    cultural wetland in China now.

When    3    (visit) the Xixi National Wetland Park on March 31, 2020, President Xi Jinping pointed out that the value of the wetlands lies in their    4    (origin) ecology, and that environmental protection should be prioritized (优先) in the wetlands.

With an area of 11.5 square kilometers, the park    5    (cover) by streams, ponds, lakes. With a large number of trees    6    (plant) in the shallows, the wetland is a natural system for providing clean water and producing oxygen,    7    makes it the “green lungs of Hangzhou” as well as    8    great platform for bird watching, scientific research and education.

In recent years, the wetland park    9    (develop) scientifically and has been playing vital role in the development of Hangzhou, a place properly    10    (name) “Paradise on Earth”

Today, I made a trip to observe Tibetan antelopes. I was struck by their beauty when I watched them moving slowly across the green grass. Also I was reminded     1     the danger they are in. They are being hunted     2     (illegal) for their valuable fur.

My guide Zhaxi told me     3     1980s and 1990s were bad times for the Tibetan antelope,     4     population dropped sharply because of shooting and habitat loss. Luckily, the government     5    (take) effective measures to save this species. Zhaxi and other volunteers watched over the antelopes to keep     6    (they) safe from attacks. Finally, with all of the     7     (effort), the antelope population has recovered and in June 2015, the Tibetan antelope     8     (remove) from the endangered species list. However, the government does not intend     9     (stop) the protection programmes, because the threats to the Tibetan antelope have not yet disappeared.

There is a long way to go to protect wildlife. Only when we learn to exist in harmony with nature can we stop     10     (be) a threat to wildlife and to our planet.

Rainbow-colored rubbish is the colorful waste created by a Swedish city with a unique cycling system. Like many cities in Sweden, Eskilstuna has an    1     ( impress) recycling record.It    2    (meet) the EU' 2020 target of recycling 50% of waste many years ago. People are expected to sort their household waste    3     seven separate categories, including food and metal. But    4    really makes the system stand out is the bright color code.

Thanks to those bright colors, scanners can select the bags and separate them    5    (efficient). The food waste in green bags is processed on site into slurry (浆) to make biogas,     6     powers the city's buses. One of the    7    (benefit) of this method is that there is less cross-pollution, so more of the recycled waste can actually be used    8    (make) new things.

Eskilstuna is committed to sending zero waste from its citizens to landfill(垃圾填埋场). Waste that can't be recycled    9    ( burn)at a local plant to produce electricity.   As countries around the world try to improve their recycling rates, some may look to Eskilstuna as    10         example to follow---as long as they think they can persuade their citizens to get busy sorting waste at home.

10 . Today, Mount Qomolangma’s peak is not a lonely place any more. Over 3500 people have    1     (successful) climbed the mountain over the past years. Meanwhile, climbers have complained about    2    (wait) for hours in the bottlenecks.

In fact, the dangerous    3    (crowd) aren't the only problem. All those climbers need     4    (bring) a lot of gear (装置) and much of them ends up being left on the mountains, becoming the world's    5     (tall) rubbish dump.

But the good news is    6     some mountaineers are overtaking it to clean up Qomolangma. Mountaineers Paul and Eberhard are part of Eco Everest Expedition which has been cleaning up rubbish since 2008. So far they    7    (collect)over 13 tons of garbage.

Some of that rubbish is even being used for    8     higher purpose. As part of the Mount Everest 8844 Art Project. a group of 15 artists Nepal collected 1.5 tons of garbage. They’ve changed the cans and oxygen tanks into 74 piece of art that are exhibited    9    Nepal’s capital. Part of the profit from sales    10     (be) available for the Everest Pakeers Association which has helped ole rubbish of the mountain.
