1 . The production of the cement (水泥) used in concrete is a major contributor to worldwide CO2 emissions. Since we use it a lot in building things, this is a serious problem. But there’s good news: Scientists have made a new kind of concrete that can trap CO2 instead of letting it out. It is a greener way to build things.
The concrete is made by D Company, cooperating with other companies, and is named G-concrete. Here’s how it’s made: A special cement mixture is placed in a curing chamber (养护室) and CO2 is then pumped into the chamber to be absorbed. The absorbed CO2 is then stuck inside the concrete, and will not be released. Crucially, it’s also just as strong as regular concrete.
“Generally, concrete hardens through a chemical reaction between cement and water,” the company explains. “But in G-concrete, over half the cement is replaced with a material we call γ-C2S. Instead of reacting with water, γ-C2S reacts with the CO2 in the air to harden. After mixing the materials needed to create G-concrete, the concrete can be placed in a location with high CO2 levels so it can absorb the CO2 and harden, trapping the gas inside. For example, a thermal power plant (发电厂) or other facilities that produce carbon-heavy waste gases can redirect the gases into a special chamber, where concrete products made with G-concrete can be placed to absorb the CO2 in the gases.”
Obviously, greener concrete is a good thing in itself. And under the right conditions, this could be used to create net-zero buildings, but if it’s not affordable and practical to produce, it’s not going to be widely adopted.
On that note, signs are actually quite hopeful. A representative of the company told us that the cost of producing G-concrete is about three times higher than standard concrete currently used. Work is being undertaken on further reducing this cost and the company believes it will become a lot more affordable in the near future.

2 . Resting on a branch in the dark is a Xingu screech owl with piercing eyes. Created by British artist Sarah Ball, the artwork refers to the scientific name of this species only found in the indigenous Xingu region of Brazil. The striking work is unique not just for its subject matter, but for how it was made: It was created with ash (灰烬) left behind after wildfires in the Amazon rainforest.
It’s part of a project called “From the Ashes”, an exhibition that ran in February in London. “Featuring 29 indigenous and non-indigenous artists, all the works were created using ink, colour and pastels produced from ash and charcoal (木炭),” said Migrate Art, the London-based social enterprise (企业) that created the project, whose goal is to help fix damage from the fires by raising money.
In March, the artworks were auctioned (拍卖) in London with estimates for individual pieces ranging from £2,000 to over £50,000, according to Simon Butler, founder of MigrateArt. “We keep 20% of what we make. The rest of it goes to the indigenous Xingu community, primarily for firefighting equipment,” he said.
Butler visited the Amazon rainforest two years ago. Witnessing the areas of the forest that had been burnt down, which he described as a “red desert that looked like the end of the world”, motivated him to create change through art. He collected the burnt remains of the rainforest, and shipped it back to London to be made into art materials. The materials were then sent to artists around the world. British artist Piers Secunda used black ink to create a painting titled Smoke In The Jungle. The collection also includes works made by members of the indigenous community.
“The sale of my work to help the Xingu Reserve buy firefighting equipment to extinguish Amazon fires is the best use of my time and resources that I can imagine,” said Secunda. “These art advocacy actions are grains of sand which build a pile. For now, the pile is small, but it is growing and will become substantial.”

Growing up in a coastal town in San Francisco, Christian had a special love for the ocean and its creatures. He had always found joy in the rhythmic tides and the ocean waves against the shore. The salty wind and the cries of the seagulls (海鸥) had been like a comforting song to him during his childhood.
However, all these changed over the years. Every time he wandered along the familiar stretch of sand, his heart sank. The once charming beach was now littered with plastic bags, bottles and other wastes, a distinctive contrast to the natural beauty that had always absorbed him.
The sight was a painful reminder of the harm the locals were bringing to the very land where he was growing up. Christian felt a deep sense of loss and responsibility. Previously, he had seen the news reports about the severe effects of plastic pollution on the oceans, and the images of sea creatures stuck in plastic wastes haunted (萦绕于脑际) him.
Determined to make a change, Christian decided to take action. He knew he couldn’t solve this problem alone, but he could start something that might grow into a powerful movement. With the passion and belief of a young man who loved his ocean and his land deeply, he founded an organization called Waves of Change. The early days presented challenges in calling on volunteers.
He began by reaching out to the students in his school. He shared the shocking reality of the polluted beaches and the urgent need to reduce plastic litter. To his delight, gradually more and more schoolmates started showing interest in the organization and many were eager to join in the cause. They were all too familiar with the beauty of the ocean and were equally saddened by the damage they had witnessed. As high school students, Christian and other members properly allocates (分配) time to balance the cause and their academic work.

Mobile phones and Personal Digital Assistants have varied precious metals and plastic. When we choose to recycle mobile phones and other such devices, it not only helps to conserve the valued resources within, but it also reduces greenhouse gas emissions that occur during manufacturing and processing.
The U. K. produces about 55 pounds of e-waste per person. Mary Creagh MP, Chair of the Environmental Audit, mentions that the household e-waste, which makes up a large number of cell phones, is piling up in a “tsunami of e-waste”.
Most Europeans change their cell phone every 18 to 24 months. The next time you have a new phone, don’t throw your old one anywhere or slide it into a drawer to gather dust. Either recycle it or if it still does its job well, consider donating it to a program that serves essential technology to low-income groups and individuals. There are also some recycling programs that work with community organizations and schools to collect unused cell phones as fundraising projects.
Apple accepts taking back the old iPhones to recycle and reuse them through its Renew pro-gram. In 2015, Apple recycled 90 million pounds of electronic waste. The composition thus recovered includes 23 million pounds of steel, 13 million pounds of plastic, and nearly 12 million pounds of glass. There were some high-value recovered materials too—2.9 million pounds of copper (铜), 6.6 pounds of silver, and 2.2 pounds of gold!
We live in threatening times when our planet is subject to risks that shouldn’t be ignored. With the decreasing metal reserves, the valuable metals inside cell phones are more precious than ever.
Let’s walk the talk and not just crawl when it comes to protecting our natural resources. Every human being on the planet has a responsibility to do their part in stopping e-waste by choosing to recycle mobile phones.
1. What can we know about e-waste from Mary Creagh MP’s statement?| A．It is alarming in amount. | B．It is kept in people's houses. |
| C．It is made up of cell phones. | D．It is mainly produced in the U. K. |
| A．Sell it to raise funds. | B．Put it in a secret place. |
| C．Keep it to continue its job. | D．Give it away for a worthy cause. |
| A．To warn us of the decrease in metal. |

7 . A new study suggests classic paintings by well-known Impressionists Joseph Turner and Claude Monet may have been influenced by air pollution during the Industrial Revolution.
Scientists don’t know exactly how polluted the cities were during that time for lack of data. However, researchers say that examining the works of Turner and Monet can give a picture of long-term environmental change with the air pollution.
The study, published in Proceedings of the National Academy of Sciences by authors from Harvard and Sorbonne universities, analyzed 60 oil paintings by Turner from 1796 to 1850 and 38 paintings by Monet from 1864 to 1901. Scientists successfully measured painters’ representation (再现) of nature, focusing on the colors as well as differences in local weather patterns which influenced coloring. They significantly found that paintings composed in Britain generally feature a greyer blue sky than works in other parts of Europe.
Researchers particularly believe changes in local sulfur dioxide (二氧化硫) emissions from burning coal may explain changes in the color contrast and intensity (亮度) of Turner’s and Monet’s works, even after taking into account the artistic trends and subject matter of the time.
Generally, artists can historically accurately represent their environment. Turner and Monet were chosen because they are famous for their landscape and cityscape paintings and also because they were active during the Industrial Revolution, when air pollution grew at a rate never seen before.
Additionally, researchers say that since the air in London was much polluted, the cities would appear grey and dull to the eyes as well as in photographs. By comparing the paintings of Turner and Monet to photos from the era, they were able to determine the painting works were definitely influenced by the change in emissions.

8 . Chaudhary quietly weaves together lengths of ropes, binding them with grass collected from the riverbank. She skillfully shapes the materials into a jewelry box. Meanwhile, she’s instructing a group of women to work out the materials. The ropes used were once the lifeline for climbers tackling Nepal’s mountains and were then discarded (扔掉). They are now finding new life, transformed by skilled hands into items to sell.
Acharya, working with the cleaning campaign, owns a waste processing business in Kathmandu, also an advocate for sustainable waste management. “Aluminum and other metal waste go through the recycling process, but we found no way to recycle ropes and gas cans,” she says. It struck her that the non-recyclable waste could be reused, but it wasn’t until she met Maya Rai that a solution emerged. Rai, leading Nepal Knotcraft Centre, helped connect Acharya with Chaudhary’s team of craftswomen in hopes of turning the mountain waste into economic opportunity. “While this seems insignificant compared to waste in the mountains, it’s a start. We aim to connect local expertise, mountain waste and local economy,” says Acharya, proudly displaying a mat made from ropes left on Mt. Qomolangma by climbers. Her goal is to ensure that no waste collected from mountains ends up in a landfill again.
Finished crafts are sold at outlets and exhibitions. The craftswomen are paid according to how many items they make and sell. With flexible hours, the project gives women an opportunity to earn money even as they maintain household responsibilities.
Eventually, Acharya hopes to expand the program to involve more women and process more waste. But progress has been slow. “We still have not found a sustainable business plan to make crafts in large quantities, ”she says. Now, she is searching for cooperators to make a model that serves not only the mountain but the communities. “After all, we are trying to craft a sustainable future.”
Each rope turned into a decorative item is a way to help local women earn a living and keep mountains clean.

9 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.
But hair possesses useful qualities and it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks,
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.
“Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier, “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.
Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氪), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes-for oil and soil, ” Hama says.
1. What can the mat made of human hair do?| A．Clear the sea of oil. | B．Improve soil. |
| C．Take in harmful gas. | D．Prevent oil leaks. |
| A．Its color and strength. | B．Its length and amount |
| C．Its structure and component. | D．Its weight and flexibility. |
| A．To state a fact. | B．To support a point. |
| C．To make a comparison. | D．To clarify a concept. |
| A．Unclear. | B．Optimistic. | C．Doubtful. | D．Negative. |
