1 . Watford and her family have lived in Curtis Bay, Baltimore for generations. Her community has faced environmental injustice. Heavy industries continued to move in her community. As a result, her neighbors have had to live with serious respiratory (呼吸的) problems.
When she knew a plan to build the nation’s largest trash-burning incinerator (焚化炉) less than a mile away from her high school, she realized she had to take action. The incinerator was being sold wrongly as clean, renewable energy equipment but actually it would be a source of brain-damaging chemicals and would release 200 million tons of greenhouse gases per year, both worse than coal burning. Watford felt she had a responsibility to warn her community to work together to shut this plant down.
She co-founded Free Your Voice (FYV), a 10-person student organization devoted to community rights and social justice. Together, they decided to start a campaign to take down Energy Answers, the incinerator’s developer. They went door-to-door talking to neighbors and organizing protests.
When it was discovered that Baltimore City Public Schools (BCPS) was going to be a customer of Energy Answers, the organization fought with the board and presented their case, urging BCPS to withdraw from the project. BCPS was convinced to cancel their contract, which in turn inspired 22 other customers to do the same. Without any financial gain, Energy Answers had no market to move forward with its plan.
Watford continues to work with Curtis Bay residents toward fair development. They have a vision for the future which includes building a zero-waste movement, a solar farm, and green jobs. She wants the entire human family to join the fight for environmental justice because survival as a species depends on our ability to take action.

3 . From airplanes to apartments, most spaces are now designed with sound-absorbing materials that help decrease various sounds of everyday life. But most of the sound-absorbing materials that can cancel out human voices, traffic noise and music are made from plastic foams (泡沫) that aren’t easily recycled or degraded. Now, researchers reporting in ACS Sustainable Chemistry & Engineering have created a biodegradable film (薄膜) obtained from seaweed, which effectively absorbs sounds in this range.
Controlling and optimizing the way sound moves throughout a room is the key to creating functional spaces. Foam sound-absorbing panels are a common solution, and they come in a variety of materials and thicknesses tailored to specific sound requirements. Most of these foams, however, are made from a type of plastic material and other chemical substances that are obtained from natural oil or petrol. To avoid petrochemicals, researchers have explored more renewable sources and biodegradable sound-absorbing alternatives. But many current options are made from plant fibers that don’t effectively decrease noises in the most useful range of sound frequencies, or they are too thick or difficult to produce. So, Chindam’s team wanted to develop a biodegradable material from a plant, which would be simple to produce and could absorb a range of sounds.
The team created films of agar (琼脂), a material that comes from seaweed, along with other additives developed from plants and varied the thickness of the films. After running the materials through a battery of tests, the researchers measured how well the films reduced sound across a range of frequencies. To do this, the team created a sound tube in which a speaker is placed at one end, and the test film is fitted over the other end. Microphones in the middle of the tube measured the amount of sound sent by the speaker and the amount of sound reflected off the film. These experiments showed that the films with many small holes made with the highest concentrations of agar had the greatest sound-absorbing qualities and performed similarly to traditional sound-absorbing foams. The researchers plan to explore ways to change the agar films to give them other desirable properties, such as flame resistance, and will explore other biologically obtained film materials.

| D．Seaweed: a Better Sound-absorbing Underwater Plant |
4 . A new study led by researchers at the Yale School of Public Health finds air pollution may negatively impact standardized test scores. Using data from the North Carolina Education Research Data Center, the researchers tracked 2.8 million public school students in North Carolina from 2001 to 2018 and measured their exposure to PM2.5 found in polluted air. While previous research has shown negative effects on academic performance, it has relied on relatively small or less representative samples. “The biggest strength of this study is that we tracked every student in North Carolina in those years, for the whole time period that they were in the public schools,” said Emma Zang, coauthor of the study.
The study also finds that test scores of ethnic minorities and girls are disproportionately (不成比例地) impacted by PM2.5 levels. “Females and ethnic minorities face sexism and racism,” said Zang. “There are a lot of policies that are not friendly towards them. So, when they’re exposed to the same level of air pollution, they don’t have the resources to lessen the negative influences.” More privileged populations, however, might have more resources that allow them to live in a better environment, such as in houses with air purifiers.
“The level of PM2.5 pollution in the US is relatively low, but students living in areas below the current air quality standard of annual PM2.5 concentration are still negatively impacted by air pollution when it comes to their test scores,” said Zang. “We should aim to strengthen the annual PM2.5 standard to better protect our children.”
Air pollution is known to contribute to disease and death, and it also negatively affects students’ academic performance even at low levels of pollution. The subsequent studies, the researchers said, would involve looking at whether the findings hold true in different areas, and also the reasons behind the ethnic and sexual differences.
1. What’s the greatest advantage of the study?| A．Tracking each student for 18 years. | B．Collecting more comprehensive data. |
| C．Measuring students’ PM2.5 exposure precisely. | D．Building links between air pollution and test scores. |
| A．benefit from current policies on PM2.5 pollution |
| B．have the lowest test scores due to their identities |
| C．lack resources to reduce the impact of air pollution |
| D．suffer from educational inequalities owing to their background |
| A．Offering a suggestion. | B．Raising a doubt. |
| C．Making a comparison. | D．Giving a prediction. |
| A．Applicability of the findings to other regions. | B．Ways to address racial and sexual differences. |
| C．Long-term impacts of air pollution on children. | D．Establishment of PM2.5 standard fit for children. |
5 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.
Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.
By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”
Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.
1. What initially caused Burrows to pick up roadside garbage?| A．He wanted to kill time by picking up litter. |
| B．He aimed to raise fund for soldiers with PTSD. |
| C．He felt annoyed to see the increasing rubbish. |
| D．He received the assignment from his employer. |
| A．It resulted in his embarrassment. | B．It increased his sense of isolation. |
| C．It worsened his stress and anxiety. | D．It brought him comfort and relief. |
| A．He feared being teased for his action. |
| B．He was lacking in advanced cleanup tools. |
| C．He was unsure about the group’s development. |

Damon Carson calls himself a matchmaker (媒人) of the never-ending waste of American society, trying not to pair people with people, but things with people.
In the late 1990s, Carson was on break from business school in Vail, Colorado, when he discovered the vast world of waste. He began thinking about creating a secondhand store that would sell old materials and keep them out of being wasted. As a result, in 2010, his company, Repurposed Materials appeared.
For nearly ten years, his company, Repurposed Materials, has not been looking to recycle the waste he gets — breaking it down to make something new — but rather finding new homes for thrown-away goods in their original forms.
Carson, a husband and father of three adult children, is far from wasteful. Frugal is how he describes himself. The clothes he’s wearing all came from a charity shop; his truck was bought with 290, 000 kilometers driven.
“Why break something down, why melt something down, if it still has value?” he asks. An old oil-field pipe might be melted down and turned into a car bumper, but it still takes an amount of power to finish the complete change. Why not leave it as a steel pipe? Why not turn it into a fence post on a farm? The only cost is transport.
American industrial facilities create and throw about 7.6 billion tons of unwanted industrial materials every year. For the moment, Carson’s unique business finds new lives for millions of kilograms of industrial waste every year.

9 . For years, twice a day Aadya Joshi walked past a dump filled with smelly rubbish in her neighbourhood of south Mumbai on her way to and from school. Originally it was meant to be the garden of the local police station. When she was 15, during her summer holidays, Joshi decided to do something about it. “I walked into the police station and was like, ‘Can I please clean your garden?’” recalls Joshi. “It took three or four weeks to eventually convince them that I was not going to give up halfway and leave them with more work.”
The plot of land covers an area of 60 square meters, about a quarter of a tennis court. But, over the course of four Sundays in the summer, with help of local residents, Joshi did more than clear it. She replanted it with native Indian plants and trees. Joshi said, “The first day that we cleaned up I made the mistake of not wearing gloves and I was sick for two weeks.”
The idea for native planting came from Joshi’s reading on the Miyawaki method of afforestation (植树造林) and the work of University of Delaware ecologist Douglas Tallamy. These both argue that planting the right trees can have a significant impact on restoring insect and animal biodiversity. The results in Mumbai were instantaneous: monkeys now hang out at the police station, and butterflies and birds have made the garden their home.
After creating the garden, Joshi developed a database of 2,000 plants unique to the Indian subcontinent and last year was awarded the annual Children’s Climate prize, founded by Swedish energy company Telge Energi. Her advice for others looking to follow in her footsteps: “If you bite off more than you can chew in the beginning, you will be stuck and lose motivation,” she says. “But something small, like your neighbourhood police station, it’s very manageable.”

10 . Coral reefs are the rainforests of the ocean. They exist on vast scales and are equally important havens of biodiversity. Reefs occupy 0.1% of the oceans.
Corals are useful to people. Without the protection which reefs afford from crashing waves, low-lying islands such as the Maldives would have flooded long ago, and a billion people would lose food or income. However, reefs are under threat from rising sea temperatures. Heat causes the algae (海藻) with which corals are living together to generate toxins (毒素) that force those coral to leave.
Research groups around the world are coming up with plans of action to see if that will help, such as identifying naturally heat-resistant corals and cross-breeding such corals to create a new type.
Doubters doubt humanity will get its act together in time to make much difference.
| A．This can cause a coral’s death. |
| B．But there are grounds for optimism. |
| C．And they host a quarter of marine species. |
| D．Coral’s global ecosystem services are worth up to $10trn a year. |
| E．This mix of natural activity and human intervention is important. |
| F．This research can also be brought to bear on trying to save entire ecosystems. |
| G．However, the assisted evolution of corals does not meet with universal enthusiasm. |
