1 . Whether due to genuine concern for the environment or the widespread criticism of plastic among consumers, many companies have invested heavily in reducing their use of plastic packaging, which may indeed have a positive environmental impact. But another trend that’s grown out of the anti-plastic movement is a lot less positive: overpackaging. More and more brands have begun adding unnecessary paper packaging on top of plastic packaging in order to make their products look more environmentally friendly, without actually reducing plastic waste.

Unfortunately, there’s a very good reason companies are adopting this clearly problematic approach. Through a series of eight studies with more than 4,000 participants, we found that consumers will accept a product’s packaging as more environmentally friendly if it’s plastic with an additional layer of paper than if the product is visibly packaged in identical plastic packaging but without the paper. These perceptions (认知) in turn make consumers both more likely to buy a product, and willing to pay more for it.

Part of what makes this overpackaging trend particularly harmful is that it is much valued by consumers who reported engaging in more eco-friendly behaviors. They were more likely to view overpackaged products as environmentally friendly. As a result, the very consumers who are most interested in pushing companies to make sustainable choices are likely unintentionally encouraging the environmentally harmful practice of overpackaging.

The good news is, overpackaging isn’t the only way to signal sustainability and attract such consumers. In our studies, we found that instead of additional paper packaging, simply adding a minimal packaging sticker to plastic packaging could clarify the misperception that overpackaged products are more sustainable, Especially for products for which plastic is necessary to ensure safe transportation and lengthen shelf life, this kind of clear messaging can help reduce consumers, discrimination against the responsible use of plastic packaging.

Of course, minimal packaging stickers certainly should only be used if a brand has actually ensured that it is using the minimal possible packaging, ideally under the supervision of a trade organization or regulatory body that maintains clear, consistent standards.

Chinese netizens recently expressed     1     (amaze) at a map online clearly marking the country’s historic relics (文物). The map     2     (make) by Wu Yunjie, who was born in the 1990s.     3     (interest) in history, Wu would often spend his spare time travelling around the country, when he was in college, and     4     (explore) ancient sites.

In 2020, he started collecting information on cultural relics and uploaded the data to the mapping software. As many historical sites in rural areas cannot be located     5     (specific) , Wu did a lot of field research. “The job is rather difficult     6     I have much joy in it．I’m happy to make people more aware of the huge and rich historical heritage (遗产) from China’s long history,” he said.

Now, the map     7     (include) nearly 10,000 relics or museums. Many valuable temples, bridges and towers     8     have been lost in the country are also shown on the map. One post online said “The ancient tower around my house on the map! I can’t wait to visit     9    .”

However, in Wu’s eyes, the map is just     10     step forward, as it records a very small part of the cultural relics in the country, and he still has a long way to go.

3 . An adult African elephant consumes about 223 liters of water and 3,080 pounds of roots, grass and fruit daily. That’s like having 634 cans of soda and 1,200 hamburgers every day. This keeps them moving thousands of miles across Africa each year. Elephants usually migrate between March and May. Females live in groups with their children, and quickly run out of the food supply. They hit the road in search of food. Male elephants live alone, so they don’t use resources as quickly as the females. Instead, they migrate during their mating cycle. When the females pack their trunks, so do the males.

During migration, elephants face short water supplies and extremely high temperatures. But people are their number-one problem. Poachers (偷猎者) kill 35,000 elephants each year for ivory. Many African farmers build fences (栅栏) to protect crops and cattle, which might block regular migration paths. Traffic roads affect elephant migration, too. During one study of 28 elephants in Central Africa, only one female crossed an unprotected road.

Scientists, wildlife organizations and governments cooperate to find solutions for Africa’s elephants. “To unlock the secret of where elephants move and how they move, we place collars (项圈) with a satellite unit inside,” Dr. Michael Chase says. GPS collars help map which routes elephants use most so that countries can establish protected elephant passages.

Locals come in as well. James Isiche, East Africa Director of the International Fund for Animal Welfare says, “We have got the community on our side by a project; they’ve agreed to partner with us to conserve elephants.” The local community run wildlife parks to attract tourists. “This project helps us take care of both the wildlife and our cows,” says Sikira, a tribal elder in Maasai, Kenya. Protecting elephant migration routes allows these gentle giants to survive.

4 . An impressive invention made by a 17-year-old teenager, called Anna Du, is helping to clean up small pieces of plastic from the ocean.

While walking along her local beaches in Massachusetts, the young student began collecting waste plastic bags and bottles. But what she noticed was a large number of tiny pieces of plastic or microplastics that were impossible to pick up. At just 12 years old, Du set out to solve the problem. After testing a few prototypes(原型)in her backyard, she invented a remotely operated vehicle that uses the infrared camera(红外摄像机)to detect microplastics on the ocean floor. More recently, Du has also created a simulation(模拟)model that uses artificial intelligence to predict where microplastics are located.

Du’s robot invention has earned her awards at top science fairs in the US, and she’s now a nationally recognized advocate for microplastic awareness and pollution prevention. “When I first started doing science fairs, I had no idea that a young girl without lots of money and just a little advanced engineering knowledge could make a difference in the world. I’ve learned that I truly love working on a problem that’s so much larger than me,” Du said.

Du has also released a new book to help spread the word not only about the dangers of microplastics but also about the ways to relieve the problem. Titled Microplastics &Me, the book follows Du’s own story of how she went from worrying about the environment to designing award-winning solutions. Writing for kids her own age, the young girl alerts her readers to the threat of microplastic pollution and urges them to care about the environment. The book hopes to encourage young students to get into science, technology, engineering and math(STEM)subjects and to inspire a new generation of inventors and engineers. What’s more, Du has even raised more than $7,000 to distribute the book free to kids and libraries in high-need communities.

5 . Washing machines are one of the greatest inventions of the last few centuries.They have made life easier. Unfortunately, washing machines also contribute to the environmental issues of energy use and micro-plastics flowing into the oceans. That is why the washing machine manufacturer (制造商), Samsung, and the outdoor-wear company, Patagonia, are working together to make a change.

For Patagonia, the issue of micro-plastics has been on its mind for years — its woolen jackets release many microfibers. As for Samsung, new requirements throughout the world have forced many producers to start thinking about ways to help reduce the number of micro-plastics. There are currently more than 14 million tons of micro-plastics floating in the oceans. Though people previously think of things such as plastic bottles and fishing lines when it comes to plastics in the ocean, thousands of micro-plastics are released into seas with every wash.

The issue is a sort of catch-22. In order to reduce energy costs, manufacturers try to make their machines more efficient. These machines use hotter water and are designed to create more friction (摩擦) between the clothing in the machine. However, both of these things lead to the release of more micro-plastics. So, using Patagonia clothes as test cases, Samsung came up with a two-fold solution: One is a technology called Eco-bubbles, which creates more bubbles to make the detergent (洗涤剂) more powerful, and the other is a water purifier that can filter (过滤) out more micro-plastics.

The cooperation between the two companies is proof of how complicated protecting the environment can be. On the one hand, clothing that is well-constructed and durable is a weapon in the fight against fast fashion. On the other hand, the material used to make those clothes and the way they are washed can also add pollutants to the environment.The same goes for washing machines. There is no one-size-fits-all solution. The fight against climate change requires creative thinking and learning how to attack a problem from many angles. This will certainly lead to even more strange and fruitful cooperation between the environmentally conscious companies.

1. What is Samsung’s purpose in partnering the outdoor clothing company?

A．To limit the use of micro-plastics.

B．To solve the issue of energy waste.

C．To find a solution to micro-plastic pollution.

D．To produce high-efficiency washing machines.

2. What does the underlined word “catch-22” in paragraph 3 refer to?

A．A tricky situation.	B．A questionable fact.
C．A possible dream.	D．A practical method.

3. Which of the following will reduce the release of micro-plastics during washing?

A．Using hotter water.

B．Creating more friction.

C．Using powerful detergents.

D．Adding a water purifier to washing machines.

4. What does the cooperation between the two companies show?

A．The difficulty in fighting against fast fashion.

B．The complexity of environment conservation.

C．The influence of humans’ active action.

D．The importance of creative thinking.

6 . Re-purposing diapers to make building materials would reduce the amount of garbage that goes to a landfill. It could also make homes more affordable. Maybe giving used diapers a new use could help tackle both problems.

Building material—especially those that are used for strengthening structures — are often expensive. They’re often the biggest hurdle to making homes affordable. So researchers have previously investigated unusual materials that could save costs. These materials included many that would otherwise pile up as waste, such as fly ash.

“There is a big need in developing countries such as the Southeast Asian nation, Indonesia. There, demand for low-cost housing outstrips what’s available. The number of people in Indonesia’s cities has climbed by about 4 percent per year in the last 30 years. By 2025, more than two-thirds of Indonesians are expected to live in urban areas. Indonesia’s population boom is intensifying the demand for housing,” says Siswanti Zuraida, an environmental engineer in Indonesia.

“Despite the need for more affordable housing, there are significant problems that stand in the way of adopting diapers,” Zuraida says. Used diapers contain wood pulp, cotton and plastic, which are potentially useful building materials. Diapers plastic components would have to be separated from the organic fibers, a complicated recycling process currently available only in developed nations. And Indonesia’s building regulations restrict together-materials to bricks, wood, steel and concrete (which is used to hold bricks together) — materials that also bear a high cost in terms of carbon emissions.

But reusing diapers might not be that environmentally friendly, especially on a large scale. “It’s tricky to separate dirty diapers from waste and disinfect them. So it would take a lot of energy to recycle diapers. It’s maybe worthwhile to start thinking about ways to replace single-use diapers with something less frequently thrown away,” says Christof Schrofl, a chemist who works at Technische Universität Dresden in Germany.

1. Which statement describes the idea of re-purposing diapers best?

A．No pains, no gains.	B．Waste not, want not.

A．It is illegal to use diapers as building material in Indonesia.

B．Making building materials has little effect on climate warming.

C．The plastic components in diapers can make buildings stronger.

D．Developed countries have difficulty separating organic fibers on diapers.

4. What is Schrofl’s attitude towards reusing diapers?

A．Indifferent

B．Supportive.

C．Admiring.

D．Objective.

7 . Johannes Fritz, an Austrian biologist, needed to come up with a plan again if he was going to prevent his rare and beloved birds from going extinct.

To survive the European winter, the northern bald ibis needs to migrate south for the winter over the Alps. But shifting climate patterns have delayed when the birds begin to migrate and they are now reaching the mountains too late to make it over the peaks, locking them in an icy death trap. Determined to save them, he decided to teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. He was confident that he could succeed in this daring, unconventional plan.

Some 400 years ago, the Europeans hunted these birds without stopping and devoured the last in the wild, causing the birds to disappear entirely from the wild. When Mr. Fritz was born 56 years ago, the northern bald ibis could be found in Europe only in captivity (圈养).

Mr.Fritz has spent his career reintroducing the birds into the wild. Through years of trial and error, he learned to fly like a bird. He modified (改装) a lightweight aircraft so it would fly at speeds slow enough for the birds to keep up. In 2004, he led the first flock from Austria to Italy, and has since led more migrations. But the route he originally taught the ibises does not work successfully. With climate change warming the area where the birds summer, they now start their migration at the end of October instead of the end of September. The trip is expected to take about six weeks, “Still, we’re optimistic that it’ll work,” said Mr. Fritz.

His family and colleagues witnessed the risks he was taking. “But the unavoidable risks are necessary,” Mr. Fritz said. “It’s not so much a job, but my life’s purpose.”

1. What was Johannes Fritz’s plan?

A．To shorten bald ibises’ migration route.

B．To lead bald ibises to migrate on a new route.

C．To better the climate patterns for bald ibises.

D．To find out a safer destination for bald ibises.

2. What does the underlined word “devoured” in paragraph 3 mean?

A．Destroyed.

B．Abused.

C．Released.

D．Raised.

3. Why was Mr. Fritz’s initial route for the birds ineffective?

A．Owing to the long time it consumes.

B．For the slow speed of his modified aircraft.

C．Because of the toughness along the first route.

D．Due to higher temperatures in the summer habitat.

4. Which of the following can best describe Mr. Fritz?

A．Honest.

B．Innovative.

C．Straightforward.

D．Demanding.

8 . People flood into cities for understandable reasons: more job opportunities, more cultural diversity and larger communities. Yet living in a concrete-walled, green-poor, urban environment takes away from our-very essence our fundamental need to be close to nature. We can’t quite break the link with our evolutionary (进化的) past and part ways with our origins. Surrounding ourselves with walls and ‘screens, we tend to pay a price, often with our health and quality of life.

In Japan, a populous country with vast expanses of green forests, an ancient tradition, known as shinrin-yoku, or forest bathing, tries to balance out the pressure from urban living. It’s the practice of spending prolonged periods of time with trees to gain from their many health benefits. In a book hitting shelves this month, Forest Bathing: How Trees Can Help You Find Health and Happiness, Dr. Qing Li, the world’s foremost expert in forest medicine, introduces readers to the valuable practice of forest bathing. The book features more than 100 color photographs of forests around the world. One may reject this kind of book as yet less convincing, but the point is that Li has not just practiced forest bathing, but has also studied its impact on people’s health through numerous scientific studies. He has data to support his claims, collected in a long list of expert-reviewed articles at the end of the book.

The book lists studies that consistently show-a substantial, reduction of stress hormones (应激激素). Essential tree oils found in forest air increase energy levels by more than 30 percent and improve a general state of well-being, including improvement in sleep.

Scientific results apart, the, concept of forest bathing shouldn’t be so surprising. Who hasn’t felt an inner sense of well-being when walking along a quiet forest path? Stepping into a forest, away from the artificial sounds and smells of urban life, does feel like pushing a life reset button, reestablishing a connection with our deepest needs.

To celebrate this wonderful book and. what seems to be a rediscovery of forest bathing in our life, I’m going to go now—to take: my forest bath.

9 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The Great Wall of China is a series of fortifications (防御工事) built along an east-to-west line across the historical northern borders of China.

In 221 BC, Emperor Qin Shihuang     1     (order) the walls of the Qin, Zhao and Yan kingdoms in the north to be joined after he united China. The new wall stretched (延伸) from Lintao to Liaodong, with a total     2     (long) of over 20, 000 li.

With the rise of the Tang Dynasty, the Great Wall lost     3     (important) as a fortification. During the Song Dynasty, the Chinese     4       (force) to withdraw (撤退) under threat from the Liao and Jin peoples in the north,     5     took over many areas on both sides of the Great Wall. The powerful Yuan Dynasty     6       (establish) by Genghis Khan finally controlled all of China.

The Great Wall became again a military fortification for Mongolians. It was during the Ming Dynasty that the Wall took on     7     (it) present form. At that time, it stretched some 6, 300 kilometers from the Yalujiang River in the east to Jiayuguan Pass in the west, and is known     8     the Ten Thousand Li Wall.

Today, the Great Wall is     9       (general) recognized as one of the most impressive     10       (wonder) in the world. It is the only man-made structure that is visible from space.

10 . A compost (堆肥) program at the Wesley School in Los Angeles is helping kindergarten through eighth grade students to teach them ways to solve human-driven climate change. For the past year, 5, 200 pounds of food waste from the school has gone into compost containers rather than a landfill where it would just break down and produce planet-warming gases.

The school workers could have easily thrown the food waste into a city-provided green bin (垃圾箱) . But taking it out of sight, which would have been easier, would have missed the point, says science teacher Johnna Hampton. “When it’s invisible like that, they don’t see it, but they know it doesn’t sink in (心安) .”

When sixth grader Finn saw the finished compost pile, it sank in. “That’s my orange chicken in there,” he says. “That’s not just like any food. Somewhere in there is my food.”

The school will use the compost on plants around campus. Some will be offered to families that want to use it at home, and whatever is left will be donated.

Fifth grader Sloan felt so encouraged by the school’s compost program she decided to take climate action outside of school. Along with several other fifth graders, Sloane says, “We did a lemonade stand at our friend’s house and we made over $200, and we donated it.” They also helped create a petition (请愿) to replace the plastic forks and spoons in the school cafeteria with compostable ones.

Fifth grader Kingston was excited to learn his food waste will help grow new food on campus. “It feels good that you’re doing something that helps the planet, instead of just sitting and watching it get destroyed,” he says.

Jennifer Silverstein, an expert on climate, says the school’s compost program checks a lot of the boxes for effective, positive climate education to help youth understand the crisis of human-caused climate change.

1. What is the purpose of the compost program?

A．To prevent wasting food.	B．To deal with climate change.
