1 . Walking or running outdoors, people usually see rubbish all over the ground. Well, some people are doing something about it.
A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community(社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish.
Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community.
Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories.
As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.
| A．And that is how plogging was born! |
| B．In other words, plogging is equal parts of exercise and community service. |
| C．There are people all around the world doing this. |
| D．They are plogging! |
| E．You get to know your neighbors. |
| F．And plogging does good to your mental health. |
| G．Usual jogging burns about 235 calories. |
2 . While pedaling hard on a bike, do you feel like you are saving the planet? Or do you just feel out of breath? In fact, cycling is now considered one of the ultimate weapons humanity can use in the fight against climate change.
The United Nations General Assembly passed a resolution in March supporting bicycles as a tool for dealing with climate change. The resolution calls on member states to “integrate the bicycle into public transportation, in urban and rural settings in developing and developed countries”, with all 193 members of the UN unanimously (一致同意地) adopting the resolution.
This decision has received a positive response from numerous groups in support of cycling and environmental awareness internationally. “It is an important step toward the recognition of cycling as an important mode of transport,” said the European Cyclists’ Federation.
The resolution from the UN comes at a time when climate change has returned to the center of global attention. On Feb 28, the UN published a new report assessing recent climate change trends. The report warns that the global average temperature will rise by 1.5 C above pre-industrial levels (1850-1900), with more than 40 percent of the world’s population being “highly vulnerable” to these temperature changes.
In May 2020, bike sales in Spain increased 22-fold (22倍) compared with 2019. In London, large parts of the city are being closed off to cars so that people can walk and cycle safely. Cities like Berlin and Montreal have also added new, wider bike lanes.
More importantly, the resolution focuses on bike-sharing services, which could be seen as recognition of China’s bike-sharing success, noted CGTN.
China has some of the largest bike-sharing systems in the world. The country has more than 360 cities with dockless (无桩的) bike-sharing systems, with nearly 20 million bicycles for an average 47 million trips each day, according to China’s Ministry of Transport. This transportation option that produces zero emissions reduces the amount of CO2 released into the atmosphere by 4.8 million tons every year, according to a 2020 report from the World Resources Institute.
1. According to the first paragraph, when cycling you may feel________ .| A．relaxed | B．proud | C．anxious | D．nervous |

3 . A major new facility to pull CO2 out of the atmosphere has started operating in Iceland, which is a boost to an emerging technology that experts say could eventually play an important role in reducing greenhouse gases.
The plant in southwest Iceland is the biggest of its kind, its builder says. It is able to capture(捕获) 900 tons of CO2 every year but it needs heat and electricity to work. It is using energy produced from waste and is built on the roof of a waste incineration plant, and through the burning of rubbish, energy is generated.
Human-sized fans are built into a series of boxes. They take CO2 out of the air, catching it in spongelike filters(过滤器). The filters are blasted with heat, freeing the gas, which is then mixed with water and pumped deep into deep underground basalt caves(玄武岩洞穴), where over time it turns into dark-gray stone. Pumping CO2 into the ground is just one way to deal with it. The makers are also selling the gas to be used again. The CO2 can be captured just a few 100 miles away. It is pumped through an underground pipeline directly into a greenhouse. Vegetables and plants love CO2 and higher concentrations of the gas within the greenhouse improve the growth of plants.
By 2050, humanity will need to pull nearly a billion metric tons of CO2 from the atmosphere every year through direct air capture technology to achieve carbon neutral goals, according to International Energy Agency recommendations. The plant in Iceland will be able to capture 4, 000 metric tons annually — just a small amount of what will be necessary, but one that Climeworks, the company that built it, says can grow rapidly as efficiency improves and costs decrease.
“This is a market that does not yet exist, but a market that urgently needs to be built,” said Christoph Gebald who co-founded Climeworks. “This plant that we have here is really the blueprint to further increase the size and really industrialize.”

4 . Japanese researchers placed electronic devices(装置)on seals(海豹)in Antarctic waters to collect surprising information about the environment there. Japan’s National Institute of Polar Research started the research project in 2017. The team recently reported its results in a study in the publication Limnology and Oceanography.
Eight Weddell seals were fitted with the devices,which have antennas(天线)to send electronic signals.The 580-gram monitoring devices were attached(缚上;系上)to the animals’heads. They were designed to measure data such as water temperatures and sea salt levels.
Investigative teams on ships have difficulty reaching important research areas in Antarctica. These include areas along continental shelf formations where ice is attached to the shore, the National Institute of Polar Research said in a statement. Nobuo Kokubun led the project. Since the seals are active year-round, Kokubun added, “I thought we should have them collect the data.”
He told Reuters that the research also helps scientists follow the seals’ behaviors and learn about their relationship to the environment. “During the summer, we can go to Antarctica on icebreakers to conduct actual research activities, so that we can collect data there.” Kokubun said. ”But during the winter. such things cannot be done in so many places.“
Information gathered from the seals showed that one of the animals traveled as far as 633kilometers from Japan’s Showa Station in Antarctica. Another dove to a depth of 700 meters.Kokubun said the scientists learned from the data that warm seawater from the upper levels of the open sea reached Antarctica from March through the winter of 2017. The water flowed below the ice, bringing in sea creatures like Antarctic krill, an important food for seals.
Kokubun and his team plan to keep finding new ways to further examine the effects of climate change on Antarctic coastal areas. Next, he hopes to make the device small enough to fit on other animals at the South Pole, such as penguins,“The advantage with penguins is that they come back to the same place and we can collect data from them immediately,”Kokubun said.

5 . Zhang Fan, 36, a movie visual effects designer who returned to Beijing from New Zealand for work last year, was surprised by the improvement to the city’s air quality. “I remember the smell in the air and the frequent smoggy days before I left in 2013, after getting a job offer from a film company in New Zealand, ” he said. Last year, a Chinese company offered Zhang a more promising position, so he returned, saying that he could find more opportunities in his line of work in Beijing than elsewhere. In addition to rapid economic development in the Chinese capital, he said the most impressive change is the local air quality. “People discussed air pollution a lot when I was in Beijing previously. Now, it seems that the topic has disappeared completely, as every day is good in terms of air quality,” Zhang said. “The sky in Beijing these days is so clear. ”
On Jan. 4, the municipal authorities in Beijing announced a comprehensive success in improving air quality, with the city’s annual average concentration of PM2. 5 in the air, falling to 33 micrograms per cubic meter, and ozone (臭氧) concentration dropping to 149 mcg per cu m last year.
Yu Jianhua, spokesman for the Beijing Municipal Ecology and Environment Bureau, said at a news conference, “This is a milestone for Beijing’s hard work in fighting air pollution and also means that the city has met its air quality target outlined in the 14th Five-Year Plan(2021-25) ahead of schedule. Beijing has demonstrated to the world over the past 20 years that a mega city with a rapidly increasing GDP, vehicle count, population and energy consumption can move forward to cut air pollution effectively. The PM2.5 reduction over the past few years has surpassed that of developed countries during the same period.
According to the Bureau, the city’s average concentration of PM2.5 dropped by 63 percent last year from 2013, an average annual reduction of about 8 percent. The city experienced 288 days of good air quality last year—up from 112 days in 2013—and just eight days of heavy air pollution. This achievement is clear to see and exciting, but it has not been easy work.
1. Why did Zhang Fan returned to Beijing?| A．He was tired of his life abroad. | B．He has a deep affection for the city. |
| C．The city’s air quality has improved. | D．A golden chance was offered to him. |

6 . Kenya has been at the forefront of the global war on plastic since 2017, when officials outlawed plastic bags. In 2020, the government raised the demand with a ban on single-use plastics. Unfortunately, tons of industrial and consumer plastic waste continue to get poured into landfills daily. However, if 29-year-old Nzambi Matee has her way, the unsightly plastic garbage mountain will soon be transformed into colorful bricks.
The materials engineer’s search for an effective solution to controlling plastic pollution began in 2017, when she set up a small lab in her backyard. It took her nine months to produce the first brick and even longer to convince a partner to help build the machinery to make them.
She says, “I wanted to use my education in applied physics and materials engineering to do something about plastic waste pollution. But I was very clear the solution had to be practical, sustainable and affordable. The best way to do this was by channeling the waste into the construction space and finding the most efficient and affordable material to build homes.”
Her company, Gjenge Makers, now hires 112 people and produces over 1,500 bricks a day, which are made using a mix of plastic products that can’t be reprocessed or recycled. The collected plastic is obtained directly from factories or picked by hired locals from landfills and mixed with sand, heated at very high temperatures, and compressed (压缩) into bricks that vary in color and thickness. The resulting product is stronger, lighter, and about 30 percent cheaper than traditional concrete (混凝土) bricks. Most importantly, it helps repurpose the lowest quality of plastic.
Matee, recognized as one of the Young Champions of the Earth 2020 — the United Nations’ highest environmental honor — is far from done. Her dream is to reduce rubbish by increasing production and expanding her offerings. She says, “The more we recycle plastic, the more we produce affordable housing…the more we create more employment for the youth.”

7 . As time goes on, people have come to realize the importance of protecting the environment. But they can’t deal with everything by themselves. Take small steps, and you can make a difference.
●Think Green. Think about the environment as you live your life. If you turn off lights and TV when leaving the room, you’ll save energy. If you take shorter showers, you will save water.
●Shop Green. Shopping is fun, but buying things you don’t need is wasteful and even bad for the earth. Before you buy something, ask yourself how much you will use it, and whenever possible, buy things locally made instead of those shipped from far away.
●Dress Green. What really matters is not the colour. It’s how the clothes were made. So look for products made from environmentally friendly(环保的)materials.
●Study Green. What’s better than learning about the environment? Save it while you learn. It can be as simple as using both sides of a piece of paper before you recycle it.
1. What does the writer want us to do?| A．Know some facts. | B．Deal with everything at once. |

8 . From littering the highest mountain peak to the deepest sea, we have messed up the environment and not left a single spot clean. Plastic pollution was also the theme for the last year’s Environment Day, but has anything changed?
With a “hope” to change things, a 150 feet long and 12 feet high “Wall of Hope” has been constructed using 15,000 discarded bottles collected from various sources such as streets and roads in Mussoorie and the surrounding region, which encourages the tourists to keep the surroundings clean.
Mussoorie attracts armies of visitors from neighboring cities every month so that it sometimes gets choked by over-tourism. But then, people hardly paid attention to the “saving the environment” cried these days. So, in order to convey this message in a meaningful and beautiful way, the locals of Mussoorie came up with this unique concept to remind travelers of the litter they leave behind.
The wall was built by over 50 volunteers that are basically school and college students who stepped forward to help bring this idea to life. For establishing this, plastic bottles of different shapes, sizes, and colors have been collected and fixed in this wall. Seeing their tireless efforts, the village locals also joined in later to help turn this project into a success story and then it spread like wildfire. They are actually admiring this new addition to the landscapes of Mussoorie, saying that the town looks even more beautiful now!
The wall was designed by Subodh Kerkar, founder of the private art gallery Museum of Goa. Talking to Hindustan Times, Kerkar said, “The wall will draw structural strength from steel pillars (柱子) being fixed two feet deep into the ground. The structure is completely rain and wind proof. I hope the wall will inspire a sense of beauty and will add color to the peaceful background of the hills.”

9 . Angela Pozzi didn’t like seeing plastic trash washing up on the shore near her home in Bandon, Oregon. She wanted to unite her community to clean it up, so she started an organization and called it Washed Ashore: Art to Save the Sea.
Volunteers help clean up Oregon’s 300 miles of shoreline. Then, using only plastics from the beach cleanup, Ms Pozzi and her staff and many, many volunteers create sculptures of sea animals. Ms Pozzi says, “I want to create sculptures that, hopefully, will make people consider their plastic purchases and be aware of how so much plastic ends up in the oceans.”
Since 2010, more than 10,000 volunteers have collected 21 tons of trash and helped create more than 70 works of art. Four traveling exhibits have displayed the sculptures in more than 18 places. Shedd Aquarium in Chicago, Illinois, hosted an exhibit through September 2018.
People have used plastics to create life-saving medical devices, inexpensive containers and gadgets, and toys, of course. But unlike wood, cotton, and other natural materials, plastics don’t break down into anything useful to other living things. Instead, they stay for years in landfills, waterways, and the oceans. The materials are harmful to some sea animals, such as turtles, sea lions, and birds. Some of these creatures eat plastic objects that look like food. Others become entangled (被缠住) in plastic nets or packaging.
Ms Pozzi gives credit to everyone who helps. “One person didn’t create these sculptures,” she says. “Some people have picked up the plastic; others have sorted the items by color. Still others have washed each piece of plastic trash. Volunteers have drilled holes or helped to make the small wire-stitched panels, while others welded (焊接) the giant frames. I do the heads and detail work, and my staff and I take all the pieces everyone contributes to finish the work.” Says Ms Pozzi, “Until we run out of plastic on the beach, the work will continue.”

10 . Puppies can be taught. So can human children, though not for the first couple of years. Now, in the hope of fighting climate change, Dr Jan Langbein, of the Fredrich-Loweffler-Institut in Germany, and his colleagues hope they can train cows to use the toilet, too.
Cow pee（尿）contains a nitrogen-rich substance that, when broken down by enzymes（酶）, is transformed into ammonia（氨）. Bacteria in the soil, in turn, transform that ammonia into nitrous oxide, a greenhouse gas. Collecting and treating cow pee before the ammonia can be produced might, therefore, seem like a good idea. But it has proved difficult in the past without limiting the cows to small areas, which is bad for their welfare.
As Dr Langbein describes in Current Biology, this confusing problem could be solved if cows could be persuaded to voluntarily relieve themselves in a toilet. He has developed a three-stage process to help cows master toilet training. The first job was to establish the toilet. Calves（小牛）were limited to a toilet and rewarded with treats after peeing in it. Next, they were given the freedom to wander around a path outside the toilet. Peeing in the toilet were rewarded; those in the path were gently punished with a spray of water. Finally, the path was extended, to allow the animals to practice self-control over a greater distance.
Of the 16 calves involved in the training process, 11 were considered successfully toilet-trained by the end of it. Their overall performance, say the researchers, was almost comparable to that of human children. The animals managed to pee in the toilet around 77% of the time.
The next step, says Dr Langbein, is to see if cattle on a working farm can be similarly trained. Whether farmers will be keen is another question. Building toilets and training animals costs time and money, after all. But when it comes to climate change, every little helps.
