Every Wednesday at 7 pm, a group of running enthusiasts from different countries gather at a bar in Shanghai before setting     1     on their 5-kilometer run. But this is no ordinary run. These people     2     (arm) with trash (垃圾) bags. The members of this group don’t simply run for the sake of good health. They do it for the sake of the Earth     3    well.

Called “plogging”, this new fitness activity originated in Sweden in 2016 and was introduced to Shanghai in 2018. The term is a combination of the words “jogging” and “plocka upp”,     4     means “pick up” in Swedish.

By the summer of 2018, just a few months after Trash Running China was founded,     5     (it) WeChat group had grown to include more than 400 runners. To make the activity more fun for both     6     (newcomer) and regular ploggers, Trash Running China also     7     (frequent) organizes longer weekend runs in the suburban areas. “We want more people to hold small ‘plogging’ groups and have a     8     (responsible) to organize trash running activities in their own neighborhoods,” says Eisenring, who founded Trash Running China. “ ‘Plogging’ is a way     9     (know) the people and the city a bit more,” says Robbin Trebbe, one of the     10     (late) runners to join the group.

Like all big cities, Paris has a traffic problem: lots of cars, traffic jams and pollution from exhaust fumes (废气). So since 2007, the city     1     (begin) a plan to improve the situation.

Under the Velib scheme (公共自行车计划), people can take a bicycle, use it as long as they want, and then leave it at the same or another bicycle station. The first half hour is free,     2     if you don’t return it after 30 minutes, you have to pay. It is only 1 a day or 29 a year. The bicycles are as heavy as 25 kilograms, and they’re all grey and have    3    (basket). There are a large number of them in the city, and the bicycle stations are more than the subway stations!

Paris isn’t the first city     4     (operate)a scheme like this. Not everybody thinks it’s a great idea. One Parisian (巴黎人) said, “These bicycles are only suitable     5     short journeys. If people want to travel across the city, they won’t use a bicycle-they’ll still use their cars.”

A city spokesman said, “The bicycle scheme won’t solve all our traffic problems, but it might work in    6    (reduce) air pollution. Traffic, together with factory fumes,           7     (be) a big problem. Global warming and dramatic climate changes are becoming more and more serious,     8    is partly because rain-forests are    9    (gradual) disappearing. And it’s also because there’s so much pollution. There aren’t any simple answers to traffic problems and pollution in cities, but the bicycles might help people lead a healthier life. Unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get even       10     (bad).”

A       1     (library) in Indonesia’s Java island is lending books to children in exchange for trash they collect in a novel way to clean up the environment and get the kids to read more. Each weekday Raden rides her three wheeler with books       2     (pack) up at the back for children in Muntang village in exchange   for   plastic cups, bags and other waste.

She told Reuters she is helping cultivate reading in the kids as well make them aware     3    the environment. As soon as she shows up, little children, many of whom     4     (accompany) by their mothers, surround her “Trash Library” and clamour for the books.

They are all carrying trash bags and Raden’s three-wheeler quickly fills up with them as the books fly out. She’s happy the kids are going to spend     5     (little) time on online games as a result. “Let us build a culture of literacy from young age to mitigate the harm of the online world,” Raden said. “We should also take care of our waste in order to fight climate change and     6    (save) the earth from trash,” Raden said.

She collects about 100 kg of waste     7     week, which is then sorted out by her       8     (colleague) and sent for recycling or sold. She has a stock of 6,000 books to lend and wants to take the mobile service to     9    (neighbour) areas as well.

The literacy rate (识字率) for above-15-year-olds in Indonesia is around 96 percent,     10    a September report by the World Bank warned that the pandemic will leave more than 80% of 15-year-olds below the minimum reading proficiency level(熟练程度).

Today, Mount Qomolangma’s peak is not a lonely place any more. Over 3,500 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 to bring a lot of gear (设备), much of which ends up     4    (leave) on the mountain. It is becoming the world’s     5    (tall) rubbish dump.

But the good news is     6     some mountaineers have started 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 8848 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage. They’ve changed the cans and oxygen tanks     9     74 pieces of art that have already been exhibited in Nepal’s capital. Part of the profit from sales     10    (be) available for the Everest Peakers Association which has helped collect rubbish off the mountain.

Located in Erdos, North China’s Inner Mongolia Autonomous Region, Kubuqi Desert is the     1     (close) desert to China’s capital Beijing.

It was once known     2     “the sea of death”. However, in the past 30 years, the government, social organizations and local farmers and herdsmen     3     (work) together to control the desertification in Kubuqi desert.

Historically. Kubuqi was a rich city filled with water and grass. But due to climate change and over-exploitation from humans, the farmlands     4     (final) turned to desert over 2.000 years.

Controlling desertification was the only way out for people still living in Kubuqi. With the first highway going through the desert     5     (build) in 1999. People started planting trees in the whole desert. It was common for planted trees to die. But the next year, people just continued to plant more trees. Their hard work inspired the term “ Kubuqi spirit ”,     6     （ encourage）local people to move forward with great efforts.

Over three decades, tree planting technology saw continuous     7     (develop) in Kubuqi. Now workers can plant a tree in just ten     8     （ second）, and their survival rate is over 80 percent.

The 102,000 residents in the desert have enjoyed the benefits of managing desertification. Meng Keda,     9     family has lived deep in the Kubuqi Desert for generations, began a tourism business in 2006. He had     10     income of 300.000 yuan last year.
