In recent years, shared vegetable plots have been springing up in the city’s suburban districts, as more people turn to farming to escape the pressure of city life. A shared ecological farm in Beijing is a typical example, which     1     (come) with shared vegetable plots, barbecue pits, and leisure areas.“In my previous companies,     2     my colleagues would always discuss about was food quality and how much they liked organic produce,” says the founder. “This has partly made farming popular because people can see for     3     (they) where their vegetables come from and be assured of the quality.”

Mount Qomolangma, the world's highest mountain, is many things to many people. Adventure seekers and     1     （profession）climbers climb the mountain, again and again,       2     (consider) it to be an achievement. It     3     (report) that 2019 saw more than 60,000 people visit it. Imagine the amount of garbage that must have been collected.

A new gallery in Nepal is going to showcase artwork made from the garbage     4     has been removed from the mountain. The Sagarmatha Next Center, a visitors' center next to the base camp, will be hosting the gallery as a way     5     (draw) attention to the large amount of garbage left there.

Artists will create artwork using the garbage that the climbers often leave behind, including     6     (use) oxygen bottles, torn tents, ropes, broken ladders, cans and plastic wrappers. They will also teach locals how to turn it into     7     (piece) of art.

“We want to showcase how you can transform waste to precious art     8     provide employment and income,” Project director Tommy Gustafsson said. “We hope to change people's opinions about the garbage and manage it," he added.

The gallery is set to have a "soft opening" for locals in the spring. It     9     (display) artwork to raise environmental awareness and sell souvenirs. The money     10     the sale will go to conservation in the area, Gustafsson said.

Sustainable Coastlines Hawaii is a nonprofit organization devoted to     1     (keep) the state’s coastlines clean. It has been working to reduce the effects of     2     (pollute) and climate change since 2010. The program     3     (begin) when eight young people came together to discuss a problem that troubled them: trash littering Hawaii’s beaches.

“We grew from eight to twelve, and now we have over 35,000 volunteers,” Caitlyn McCall,     4     servesas a volunteer at the organization, told me in an interview.

The nonprofit’s office     5       (locate) in Kaimuki, a neighborhood in Honolulu. More than 30 coordinators are based there. They focus on three major     6     (program): sustainable events, cleanups and education. The group has organized 240 cleanups, prevented an estimated 600,000 pounds of trash from ending up in the ocean, and educated 45,000 children.

The next step for the program is     7     (carry) out their sustainability courses with Hawaii’s Department of Education. As of now, a team from the nonprofit will visit a local school to talk with students about     8     (environment) sustainability.     9     team educates kids about the lifecycle of household products, their effects on marine life, and how the items we buy can end up on our shores.

Sustainable Coastlines Hawaii also hosts free cleanups for schools. “Climate change is a concerning subject for young people,” McCall said. “We want to equip students     10     the knowledge and tools they need to feel empowered to make a change.”

Electric vehicles (EVs) are a strong weapon in the world’s efforts     1     global warming, But the effects of EVs depend on which country you are in, new research shows.

The researchers compared gas emissions (排放) caused by charging an EV to drive 100 kilometers with the emissions     2     (come) from an average gasoline car driven the same     3     ( distant).

Countries     4     charging an electric vehicle is     5     (clean) than driving a gasoline-powered car use a lot of hydroelectric (水电), nuclear or solar power. Data suggests that an electric vehicle in Poland actually     6     (create) more carbon emissions because its electric system depends so much on coal. In other European countries, however, EVs result in reduced emissions.

Germany creates a lot of electricity from the sun and wind. But they do not add to the electricity system     7     (equal) throughout the day. For this reason, the amount of carbon emissions saved by driving an EV depends on the time of day when it     8     (charge). Charging in the afternoon, when there is more sun and wind, saves 16 to 18 percent more carbon than at night when electricity systems are more likely     9     (use) gas or coal.

The gap in emissions between electric and gasoline powered vehicles has narrowed in recent years. In Europe, carmakers have been required to meet EU carbon reduction standards. They have made their gasoline engines more fuel-efficient. As     10     result, the carbon emissions of new gasoline-powered cars in Europe fell by an average of 25 percent between 2006 and 2016.
