1 . It may come as a surprise that the fashion industry is one of the most polluting industries in the world, especially when it comes to carbon emissions and water usage.     1     Clothing production releases 10% of worldwide carbon emissions. Although cotton is often offered as a more sustainable material, one cotton shirt requires 2, 700 liters of water to make, which is enough for one person to drink eight cups per day for 2.5 years.

    2     However, it’s undeniable that sustainable companies like Reformation and Organic Basics are out of most people’s price ranges. Fast-fashion clothing companies have the advantage of low prices, and when it comes down to it, most people will choose low prices over sustainability. So, how can people buy sustainable clothing when it’s not affordable?    3    

Actually, there are other ways to practice sustainable habits. Of course, the best way to limit waste is to not buy any new clothes. For example, saving up to buy more sustainable clothes and then wearing them for many years is healthier for the environment and your wallet.     4     Then you can combine them with your statement pieces to get a variety of new outfits that still feel stylish and don’t generate waste. Certainly, buying second-hand clothing is also a great option.

With ever-changing fashion trends moving at breakneck speed, consumers are easily persuaded into buying latest designs to stay stylish and sustainable.     5     Honestly, it’s unnecessary. Wearing what makes you feel confident will make you look good, and the earth will thank you for your efforts.

A．The reality is frightening.

B．However, trend is hard to keep up.

C．They have no choice but to follow suit.

D．They can’t, and moreover, they don’t have to.

E．A similar resolution is to own some basic pieces.

F．Sustainable fashion has been on the rise in recent years.

G．Industrial development is pursued at the price of pollution.

2 . 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.

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.

2. How did collecting roadside garbage affect Burrows’ PTSD?

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.

3. What concerned Burrows when he started Truckers Cleaning Up Britain?

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.

D．He worried about the local council’s disapproval.

4. What can be a suitable title for the text?

A．A Joyful Volunteer Experience	B．A Trucker’s Cleanup Initiative
C．A Fighting Hero against PTSD	D．A Platform for Environmentalists

6 . When most kids go to the beach, they’re too focused on making sandcastles and splashing around to notice litter, but several years ago, for 7-year-old Cash Daniels, noticing a plastic straw sparked a lifelong passion for saving the planet.

Cash, who is now known as the “conservation kid”, has always loved nature. He grew up fishing along the Chattanooga River, after all! But once he learned that 80 percent of all trash from land and rivers ends up in the ocean, he couldn’t sit back.

He started with cleanups along the river, something that quickly went from a family affair to a community effort with volunteers and neighbors. In 2019, Cash, together with a Canadian conservationist, Ella Galaski-Rossen, started a nonprofit called the Cleanup Kids. Despite living in different countries, they managed to create educational videos on their YouTube channel. “We hope to be a really big nonprofit that eliminates plastic in the U. S. and Canada,” Cash said. “We want to inform kids and adults in the landlocked states on how their actions are connected to the water and the ocean,” Cash said.

Cash was selected as one of America’s top 10 youth volunteers of 2021 by the Prudential Spirit of Community Awards. He also earned the title of National Honoree, where he received a$5,000 grant to go to a nonprofit of his choice, and he became the first person to win the Youth Conservationist Award two years in a row from the Tennessee Wildlife Federation.

“I want to travel the world, teach others, and help them feel connected to the ocean. Because if you are connected to the ocean-if you love it and what lives in it—you’ll want to protect it,” he said. “This is my fun, and it becomes more fun with every new discovery.”

1. Which can replace the underlined words “sit back” in paragraph 2?

A．Fall asleep.	B．Lose heart.
C．Turn a blind eye.	D．Lend a hand.

2. What is the purpose of starting the Cleanup Kids?

A．To recycle waste plastics.

B．To make instructive videos.

C．To spread marine knowledge.

D．To appeal for ocean protection.

9 . 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.

1. What is paragraph two mainly about?

A．Carson’s school lessons.

B．Carson’s journey to Colorado.

C．The start of Carson’s business.

D．The serious waste of materials.

2. What is Repurposed Materials aimed at?

A．Marketing wastes to people in need.

B．Breaking down the wasted goods.

C．Manufacturing industrial products.

D．Recycling the thrown-away stuffs.

3. How does Carson describe his life?

A．Economical.

B．Poetic.

C．Tough.

D．Risky.

4. What can we learn from Carson?

A．Well began, half done.

B．Innovative thinking counts.

C．One is never too old to learn.

D．Hard work will pay back.
