1 . In films and TV shows, police officers study fingerprints to catch bad guys. Now, conservationists (people who work to protect animals and the environment) are using a similar method to deal with the illegal overfishing of sharks.
Overfishing is when too many of a particular type of fish are caught, putting that species in danger. Many sharks are killed because of a high demand — and high price — for their fins. In some countries they are used to make shark fin soup, which some people believe is good for health. Around 100 species of sharks are protected by CITES — the Convention on International Trade in Endangered Species of Wild Fauna and Flora, which is an agreement between 184 countries that protects wildlife that is sold.
CITES has teams of people who visit ports and fish factories to look for evidence of protected species being illegally caught and sold. The idea is to punish those responsible and stop it happening, but finding evidence is difficult and can take a long time. Often, fish are sold before teams arrive and if a fish is cut up ready for sale, it’s hard to tell which species it was.
Scientists have come up with a process that studies “fish dust” — tiny traces of fish that get left on the floor at ports and factories, even after the fish have gone. Using a process called metabarcoding, they examine the DNA in it and can tell if the DNA is from a protected species. The scientists tested the method in Indonesia, where many sharks are caught and sold. They studied dust from seven sites and found evidence of 61 shark species — more than 80% of them CITES-protected. Dr. Andhika Prasetyo, the scientist who led the research, hopes the new method could soon be helping to protect endangered sea life.

2 . Unless you’ve been faithfully bringing reusable shopping bags to the store, you probably grab the plastic bags waiting for customers at the checkout. You’re not alone.
About 100 billion plastic bags are used in the U. S. each year. Unfortunately, single-use plastic bags have serious consequences once our trip to the store is over. Less than 10% of plastic bags used in the U. S. are recycled, leaving the rest to end up in landfills (垃圾填埋场), and polluting soil, oceans and other natural habitats.
To fight pollution and other environmental problems, major companies are taking steps to get rid of the use of plastic shopping bags. If you’re a frequent customer at Walmart, don’t be surprised if you notice the plastic bags disappearing over the next few months. Last summer, Walmart announced its goal to be a zero-waste company — meaning no more plastic bags.
But Walmart has announced its Beyond the Bag, an initiative (倡议) working to explore reusable options and “reimagine” the plastic bag. Target and CVS are also on board as founding partners of Beyond the Bag, and so far, the three brands have invested $15 million to come up with a brand-new bag design.
The initiative also started the Beyond the Bag challenge, giving innovators (创新者) a chance to share their ideas. The challenge ran throughout the summer of 2020, and nine winners from over 450 submissions were selected. From a station supplying reusable bag in-store to a new and improved paper bag, the winning designs cover a lot of bases. Each product now has the chance to be tested with funding from the initiative.
While a final replacement for plastic bags at Walmart has yet to be decided, there’s a more sustainable future on the horizon. And if you want to start reducing your use of plastic bags right now, check out our list of reusable bags to bring on your next shopping trip.

4 . In an effort to help out important insects like bees and butterflies, bus stops across the United Kingdom (UK) are getting living roofs. Small gardens on bus shelter roofs are being planted with flowers chosen to help support the struggling insects. The gardens provide much-needed islands of nature in a man-made environment of a city.
Humans count on bees and other “pollinators (授粉者)” like butterflies to help grow plants, such as flowers and trees. But with humans taking over more and more land for cities, roads and farms, more natural areas have disappeared. The Wildlife Trusts, a group which works to protect wildlife in the UK, says that 97% of England’s wildflower fields have been lost since World War II and the insect numbers there have dropped by 50% since 1970. Bee bus stops are a small step toward supporting these important insects.
The advertising company Clear Channel is working with The Wildlife Trusts and city governments to set up bee bus stops in cities across the UK. Bee bus stops are like ordinary bus shelters, but small gardens have been added to the roofs. The gardens are filled with flowers and plants chosen to attract bees and butterflies. The company plans to set up 1,000 bee bus stops in the UK.
Clear Channel already has bee bus stop programs in several countries in Europe. In the Netherlands, the city of Utrecht has 300 bee bus stops. Research shows that these bus stops—along with many other steps taken to support pollinators—may be helping. After decades of dropping numbers, bee populations in the Netherlands seem to have become more stable over the last few years.
The little gardens can also help to slightly lower city temperatures. Even though the bus shelter gardens are small, together they add up to a much larger area. Thirzah McSherry, who works for The Wildlife Trusts, says, “We’re living through a nature and climate crisis and we need to use every tool we’ve got to deal with it.”
1. Why are bee bus stop gardens being built in the UK?| A．To beautify the city. | B．To improve urban farming. |
| C．To solve the environmental pollution. | D．To provide shelters for pollinating insects. |
| A．Losses of forests. | B．Climate changes. |
| C．Human activities. | D．Natural disasters. |
| A．By analyzing the data. | B．By making a comparison. |
| C．By showing similar examples. | D．By presenting its bright future. |
| A．The urban environment is getting worse. |
| B．The United Kingdom is building bee bus stops. |
| C．City should build larger gardens for the insects. |
| D．The bee bus stop is the best way to save the city. |
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.

Not much happens in the sleepy village of Colaton Raleigh, where almost half of the residents are retired, so local walkers were horrified when they discovered 100 ancient beech trees were cut down.
Residents in the east Devon community are saddened by the loss of the beloved trees, which were cut down by a government agency without consulting the community or council. They were located in a special conservation area and site of special scientific interest, and were home to lots of local plants and animals.
An application was made by a local landowner to the Forestry Commission, a branch of the Department for Environment, Food and Rural Affairs. It would not comment on individual cases, but said all decisions were taken in line with its standards. Alan Pearce, a local tree manager, said, “It certainly ought to be a fairly wide consultation because it’s part of our heritage. Once they’re gone you’re talking about 200 years to regrow. The stumps (树桩) look, nearly all of them, perfectly sound and solid. I can’t see they can say they were diseased or dying. We’re meant to be planting trees, not felling (砍) them.”
He said people were “absolutely horrified”, with one walker in tears over the felling, which he suggested may have been taken to improve grassland in the nearby field.
Resident Fiona Carroll said, “Many people walk in this area as it is part of a large expanse of heathland and they are at a loss as to why this has been allowed to happen. These were valuable landscape and wildlife trees situated along an extensive ancient Devon bank. The roots had grown into large supporting structures giving many a distinctive look.”
Ewan Macdonald, a research fellow at the University of Oxford, who studies how people engage with the environment, said he was not surprised the felling had caused such an emotional reaction because of the way people connected with trees. He said, “It highlights how intrinsically (内在地) bound up things like trees, the environment and conservation are with our culture.”

7 . Every tropical (热带的) forest looks different, particularly in the eyes of an ecologist, and Peter Ellis has been lucky enough to visit a fair few. One in particular holds a special place in his heart: the rain forests of Gabon. He first visited as a Peace Corps volunteer. “It completely changed the way I think about conservation and our relationship with nature,” he says.
These days, Ellis is the global director of natural climate solutions science at the US-based conservation organization — The Nature Conservancy, where he’s presently investigating the role that logging (cutting down trees) can play in tropical forests. Logging for forest conservation may sound contradictory, and it often is. But logging in a tropical forest looks different to the practices we might expect to see. “We might imagine it as a wasteland of stumps (树桩) after a clear cut,” says Ellis. Instead, only a few trees are actually removed. A sustainably logged forest is the one that remains a breathing, rich, tropical rain forest full of trees and wildlife, thus helping keep a large part of the biodiversity while ensuring that more damaging industries don’t take its place. It can also provide a means of basic livelihood for the local people.
The two years that Ellis spent in the Gabon rain forests opened his eyes to a different method of land management. “The locals took me out into the forest and taught me the names, usages and spiritual significance of all the trees and other plants in the forest,” he says. “Science is about exact, designed experiments, but it’s also about asking the right questions. And the people who live in those places and protect the ecosystem are more likely to help us learn what the right questions to ask are.”
Tropical forests are essential to our planet’s future as they support high levels of biodiversity and act as crucial carbon sinks (碳储存器). “We need to honour, and protect them so that they can do their job to help save us all” says Ellis.

8 . Ten years ago, environmental journalist Ben Goldfarb was on a reporting trip about wildlife conservation. When he was shown around some new animal crossing structures near, Missoula, these new bridges and tunnels intrigued him. He was attracted by these beautiful human-built structures and inspired to write a book. Crossings: How Road Ecology Is Shaping the Future of Our Planet has now been published.
Through expert interviews, in-depth research and convincing analysis, Goldfarh brings to life the deadly consequences our 40 million miles of roadways have had and are having on the natural world and the creatures that inhabit it. A million animals are killed by cars each day in the US alone. Road salt pollutes lakes and rivers. And there's the barrier effect-the steady stream of traffic that prevents animals from migrating (迁徙) all together and finding habitats. Goldfarb writes that noise pollution is the most worrisome among all the road's ecological disasters. Both the engine noise and the tire noise greatly impact ecological environment.
Figures on deaths and disruptions (扰乱) are disheartening, but Goldfarb vividly describes how scientists are actively working on meaningful improvements to help animals and roads better coexist, such as wildlife crossings, from passages in Canada's Banff National Park to the famous Liberty Canyon Overpass in Los, Angeles. Another example is that in India, they built a new highway through a tiger reserve so that animals can come and go underneath the lifted freeway. Of course, that made the project more expensive, but it's ecologically the right thing to do.
Crossings is a truly important and landmark book on a subject whose full impacts continue to be disregarded or underestimated in considering conservation efforts. The book is a sympathetic, heart-warming guide to exploring the issues of wildlife survival and our own.

9 . As a committed citizen, I would never exchange the industrial style of my home city of Wolverhampton, UK, for a view of rolling hills and valleys, let alone rainforests or mountain peaks. For me, the glories of untamed nature feel a planet away.
Wilderness with Simon Reeve, a four-part BBC travel documentary, aims to fill this gap. Reeve and his crew seek out corners of our rapidly urbanizing globe so far relatively untouched by humanity.
Travelling across rainforests and ice fields, deserts and oceans, including the Pacific Ocean’s Coral Triangle, and Patagonia, they reveal the pressures there and how we might protect them from us.
Travel programmes have a rather worrying relationship with conservation, predicated as they are on “selling” a destination. When it comes to the places least influenced by humans, I realize that travelogues can lead to mass tourism and damage.
Happily, based on its first episode (集), Wilderness with Simon Reeve seems more about finding a balance between “right” and “wrong” kinds of tourism. In this episode, we visit the Congo basin, home to the world’s second-largest tropical forest, which stretches for more than 2 million square kilometers across central Africa. The three-week journey begins along the Republic of the Congo’s Motaba river in search of the Baku, hunter-gatherers who live in the jungle. After an old-fashioned knees-up to welcome Reeve, several young Baku men agree to take a camera as they climb 20 metres into the top of the tree. One man puts his arm into a beehive (蜂箱) and collects the honey.
This is just one example of the extraordinary nature in the Congo rainforest. For me, it showed the joy and surprise I felt learning about this region and its people, who aren’t treated as guardians of mysterious knowledge, but as an adaptable, responsible community moving with the times.
All told, the first episode is informative and entertaining. I still have reservations about the impact of such travel shows on conservation, but the series makes a strong case that the first step to preserving an ecosystem is to see its value.
1. What does the underlined word “untamed” in Paragraph I probably mean?| A．Wild. | B．Unpredictable. | C．Distinctive. | D．Complex. |
| A．To promote tourism in remote areas. |
| B．To encourage people to move to urban areas. |
| C．To show the beauty of rainforests and ice fields. |
| D．To raise awareness about the value of untouched nature. |
| A．Friendly but poor. | B．Honest and generous. |
| C．Curious but backward. | D．Adaptable and trustworthy. |
| A．An introduction to a book. | B．A review of a travel documentary. |
| C．A guidebook to a tourist destination. | D．An essay on influence of mass tourism. |
10 . The California sea otter (海獭), once hunted to the edge of extinction, has staged a thrilling comeback in the last century. Now, scientists have discovered that the otters’ success story has led to something just as remarkable: the restoration of their declining coastal marsh (沼泽) habitat.
Elkhorn Slough, a coastal marsh within Monterey Bay, had been experiencing severe damage. The root cause was a growing population of shore crabs, which fed heavily on the marsh plants, weakening the structural integrity of the habitat. Coastal marshes like these are not only natural defenses against storm waves but also serve as important carbon storage areas and water-cleaning systems.
The conservation-driven comeback of the sea otter has been crucial. California’s coastlines were once alive with sea otters. Sadly, they were nearly wiped out at the hands of fur traders. In the 1980s, conservation efforts aided these otters in re-occupying large areas of their former range. Now, Elkhorn Slough has the highest concentration of sea otters in California, with a population of about 100. By naturally feasting on crabs, the otters have helped a significant regrowth of plant life. Brent Hughes, a scientist working alongside Angelini, led a three-year study. Their findings were clear: in areas with sea otters, crab numbers fell markedly. This led to a resurgence in plant growth, which in turn stabilized the soil and lowered the rate of soil washing away.
As the sea otter population continues to restore, their positive impact on coastal ecosystems is likely to increase. It not only showcases the sea otter as a central species—a species that has a significant effect on its natural environment—but also highlights the essential nature of top predators (捕食者) in preserving ecological harmony. “My honest reaction was—this could become a classic in the literature,” says scientist Lekelia Jenkins. She reveals marsh restoration also helps people by reducing flooding. “Suddenly, sea otters go from just cute things we like to something that can protect our livelihoods and our properties.”
What does the underlined word “resurgence” in paragraph 3 mean?| A．Barrier. |
| B．Advancement. |
| C．Expansion. |
| D．Revival. |
