3 . Wildlife populations around the world are facing dramatic declines, according to new figures that have led environmental campaigners to call for urgent action to rescue the natural world. The 2022 Living Planet Index (LPI), produced by the Zoological Society of London (ZSL), reveals that studied populations of mammals, birds, reptiles (爬行动物) and fish have seen an average decline of 69 per cent since 1970, faster than previous predictions. The LPI tracked global biodiversity between 1970 and 2018, based on the monitoring of 31,821 populations of 5230 vertebrate (脊椎动物) species. Mark Wright of WWF says the degree of decline is destructive and continues to worsen. “We are not seeing any really positive signs that we are beginning to bend the curve of nature,” he says.

Freshwater vertebrates have been among the hardest-hit populations, with monitored populations showing an average decline of 83 per cent since 1970. The Amazon pink river dolphin, for example, has experienced a 65 per cent decline in its population between 1994 and 2016. Meanwhile, some of the most biodiverse regions of the world are seeing the steepest falls in wildlife, with the Caribbean and central and south America seeing average wildlife population declined by 94 per cent since 1970. Habitat loss and reduction is the largest driver of wildlife loss in all regions around the world, followed by species overexploitation by hunting, fishing or poaching (偷猎).

In December, governments from around the world will gather in Montreal, Canada, for the COP15 Biodiversity Framework, a much-delayed summit that aims to agree on a set of new targets intended to prevent the loss of animals, plants and habitats globally by 2030. “This is a once-in-a-decade opportunity that’s coming up,” says Robin Freeman of ZSL. He says it is vital that governments use the summit to agree on “meaningful, well measurable targets and goals”. “We need governments to take action to ensure that those goals deal with the complicated combined threats of climate change and biodiversity, in order for us to see a meaningful action,” says Freeman. But some researchers are critical of the LPI’s use of a headline figure of decline, warning it is easy to be misunderstood.

The findings don’t mean all species or populations worldwide are in decline. In fact, approximately half the populations show a stable or increasing trend, and half show a declining trend. “I think a more appropriate and useful way to look at it is to focus on specific species or populations,” says Hannah Ritchie at Our World in Data. But Wright says the LPI is a useful tool that reflects the findings of other biodiversity indicators. “All of those show they all scream there is something going really very badly wrong,” says Wright.

4 . At Cleveland Bridge, in Bath, a long line of traffic is building up. Although the Georgian structure was praised for its handsome Greek Revival style by Nikolaus Pevsner, an architectural master, it was built for horses, not cars. Repairs will close the bridge for several months, causing bigger jams and more pollution in a city where air quality is already a cause of concern.

Bath is an extreme example of a tradeoff faced by much of the country. Britain has the oldest housing stock in Europe, with one in five homes more than 100 years old. Period features are prized and often protected by law. Yet as efforts to cut carbon emissions intensify, they are clashing with attempts to preserve heritage. It is a “delicate balance” says Wera Hobhouse, Bath’s MP “What is the public benefit of dealing with the climate emergency, versus protecting a heritage asset?”

Two years ago, Bath was among the first British cities to declare a “climate emergency” when it also promised to go carbon-neutral by 2030. Yet Bath also wants-and is legally required to preserve its heritage. With Roman remains and Georgian streets that spread across the Avon Valley in shades of honey and butter, the city is designated a world heritage site by UNESCO. About 60% of it is further protected by the government as a conservation area, more than 5.000 of Bath’s buildings-nearly 10% of the total-are listed as being of special architectural or historical interest, making it a criminal offence to alter them without permission.

Many of the features that make Bath’s Georgian buildings so delicate also make them leaky. Buildings of traditional construction make up 30% of Bath’s housing stock but account for 40% of domestic carbon emissions, according to the Centre for Sustainable Energy, a charity. British homes are rated for energy efficiency on a scale from A to G; most traditional buildings in the city are an F or G.

Transport is another area where climate and heritage clash. Bath’s 17t-century streets lack room for bike lanes. Joanna Wright was recently booted out of her role as Bath’s climate chief after proposing that North Road, which leads to the university, should be closed to traffic. In two years she was unable to install any on-street electric-vehicle charging points, partly because of the “nightmare" of getting permission to dig up old pavements.

All this means going carbon neutral by 2030 looks hard, but the city is at least beginning to make compromises. In March it launched the first “clean-air zone” outside London, charging drivers to enter central Bath. A trial has made 160 electric motoreycles available to hire. And local opinion seems to be shifting in favour of sustainability. “The discussion has moved dramatically towards considering the climate emergency,” says Ms. Hobhouse.

1. What problem does Bath face?

A．It is getting more and more crowded due to the repairs that are under way.

B．Its historical significance makes it hard to reform it into an eco-friendly city.

C．It refuses to admit that the climate emergency is already a cause of concern.

D．Its promise to go carbon-neutral by 2030 wins no support from the city residents.

2. The percentage mentioned in the underlined sentence (paragraph 4) is intended to _________.

A．question the validity of the A-G scale

B．highlight the long history of Bath’s buildings

C．emphasize the buildings are not energy efficient

D．illustrate the features that Bath’s buildings share

3. It can be inferred from paragraph 5 that Joanna Wright _________.

A．failed to perform her duties well

B．managed to dig up some old pavements

C．succeeded in building bike lanes in Bath

D．removed charging points from Bath’s streets

4. What can be inferred from the passage?

A．Wera Hobhouse doesn’t care much about the public benefit.

B．Traditional buildings in Bath are not accessible to tourists now.

C．Local people in Bath used to favour heritage over sustainability.

D．Bath has been leading the way in constructing a carbon-neutral city.

6 . Farmers in southern Italy are cultivating tropical fruits like avocados and mangos. Tropical creatures such as the rabbitfish are ____ in Mediterranean nets. And the winemakers in southern France are worried that their grapes may become extinct. Fifty years ago all this would have been _____ , but since the early 1980s rising temperatures have forced some farmers to ____ grapes for some tropical fruits.

Italy and France have long been proud of their cuisines. Both countries jealously ____ the rules that say   only ham made in Parma, a province in northern Italy can be called “Prosciutto di Parma”, and only fizzy wine made in Champagne can be called champagne.

Roquefort, that most ____ of blue cheeses, was given special protection by the parliament of Toulouse in 1550. The fact of having been grown somewhere famous has traditionally been seen as a guarantee of ____ .

But climate change could ____ that. Take polenta(意大利玉米糊), a popular Italian dish consisting almost entirely of ground corn. High temperatures and drier weather have already reduced corn yields in southern Italy.

If this pattern continues and spreads ____ , will Italian polenta-makers have to order their corn from elsewhere? And what about durum wheat, which grows ____ in Mediterranean lands and is used to make pasta, flatbreads and couscous? Modelling suggests that durum yields will sharply fall there if the temperature keeps on rising.

So should we worry about the future of spaghetti? Gabriele Cola, a researcher at Milan University, is   ___ about the short term. “I don’t see crops at serious risk, because farming is more ____ and technologically capable, so it can always respond to changes,” he says.

Increased irrigation(灌溉) can ____ the effects of drought. Scientists may also breed more resistant varieties of crops. But ____ deeper change seems likely. If temperatures continue to rise, farmers in northern   Europe may find they can grow southern staples( 主食 ); polenta may ____ northern Europe. Meanwhile, the Italian southerner may also have to ____ if tropical fruits continue to spread there.

7 . Do animals have feelings?

People often assign feelings to animals. That zoo polar bear’s vacant stare must mean he’s sad. The uh-oh expression a dog flashes after knocking over the garbage indicates shame. But scientists haven’t determined whether these human-like expressions really mean anything. After all, it’s very difficult to read a dog’s mind.

Scientists believe that certain brain cells in humans called spindle cells (棱形细胞) are responsible for human social behavior and the interplay between thoughts and feelings. Studies have revealed that chimpanzee, dolphin and whale brains also possess spindle cells.     1    

Even animals that don’t have spindle cells, such as dogs, have shown behaviors that can suggest a human-like social sense.     2     Scientists report that this shows dogs are sensitive to human social cues and are able to correctly interpret them. Still, this only proves that dogs know how to find food, not that they have feelings.

Observations of apes have also revealed behavior that appears to represent various human-like desires. In some tests, chimpanzees demonstrate what looks like altruism (利他主义) helping their own kind and even other species without the expectation of a reward.

    3     In a recent study, a Barnard College researcher tested dogs to see if their guilty looks were linked to actual bad behavior. Dogs were tempted with a treat and told by their owners not to eat it. The dog’s owners weren’t allowed to see whether their pets had eaten the treat or not, but were told either that they did or that they didn’t, and were then instructed to scold the dogs that disobeyed. The experimenters noted that scolded dogs showed a guilty look whether or not they had actually done wrong.

    4     A guilty look suggests a feeling of guilt in a human but not necessarily in a dog, according to the Barnard research. Similarly, even apparent empathy (共情) behavior might not actually mean these feelings are present in the brains of animals.

A．Although these are all animals that can act people-like, the presence of these cells does not mean that the animals have feelings.

B．Anyone who claims to know what animals feel doesn’t have science on their side.

C．In recent experiments, dogs have shown that they know to follow a human’s pointed finger to find a food treat.

D．Many people think that empathy is a special emotion only humans show.

E．Other experiments have cast doubt that animal behavior can reliably signify an underlying feeling.

F．This illustrates the difficulty in accurately interpreting animal behavior as a marker of human-like feelings.

Should we be rewilding more land?

Every day in the US, 6,000 acres of open land are cleared for various purposes such as farming, housing, roads, and others. This has led to concerns among scientists     1     believe that losing more open land can harm the planet. Natural habitats such as untouched forests, grasslands, and waterways provide numerous benefits     2     wildlife habitats, clean water, and reduced air pollution. To counter this trend, efforts are underway     3     the world to return animals and plants to certain areas. However, some people argue that rewilding is     4     expensive and risky process that may not work and could cause harm.

Despite the potential risks, rewilding can help slow down climate change by restoring forests that absorb harmful gases like carbon dioxide. It can also prevent species from     5    (die) out and reset natural ecosystems. For example, gray wolves     6    (reintroduce) in Yellowstone National Park in 1995, after being hunted to extinction there. The wolves reduced the booming population of elks (麋鹿),     7     gave the plants the elks ate a chance to thrive and serve as habitat for animals like beavers and birds.

    8     its environmental benefits, rewilding can also provide jobs for workers and scientists and attract visitors to an area. Despite the potential concerns and risks     9    (associate) with rewilding, it is an important tool for protecting the planet and its diverse ecosystems. As such, efforts     10     be made to ensure that rewilding projects are conducted responsibly and with careful consideration of their potential impact on the environment.

9 . Greening the blue

Is there a “natural” way to enhance the potential of the oceans to lock away climate-warming CO₂? Planting more trees on land can help draw down more CO₂ from the atmosphere—the basis of many plans for carbon credits that companies buy to offset their emissions (抵消其排放).     1     Seaweed forests and saltmarshes (盐碱滩) are common examples.

Some regard the potential for this “blue carbon” as huge, although as yet there is no mechanism for integrating it into carbon offsetting plans. John Virdin of Duke University in North Carolina says, “    2    ” He adds, “You have to go out and measure all the carbon that’s there, you have to show that it’s not going to be lost, you have to keep monitoring it.” Virdin and others have proposed extending an existing land-based plan called REDD + (reducing emissions from deforestation and forest degradation) to the ocean, but that is an idea whose ship has yet to sail.

    3     In March, the UK government’s climate adviser, the Climate Change Committee, found that restoring and creating seagrass and saltmarsh ecosystems in the country would only lock away a small amount of CO₂, removing “well below” 1 million tonnes a year. Nonetheless, these are efficient carbon stores according to the committee.     4    

A．Using the oceans as a solution to climate change is hardly a new idea.

B．There is still some doubt about how big the marine offsetting effect might be.

C．It’s really hard to turn blue carbon conservation and restoration into carbon credits that you can sell.

D．Something similar might work in the oceans, by stimulating the growth of marine and coastal ecosystems.

E．And conserving them is important given how much fishing and other activities have degraded them.

F．The big objection to all these plans is the possibility of negative environmental side effects.

Meet the Islands

Located 86 km north-east of Bougainville in the South Pacific, the Carteret Islands of Papua New Guinea are composed of low-lying islands     1     (distribute) in a horseshoe shape, with a total land area of 0.6 square kilometers and a maximum elevation of 1.5 meters above sea level.

The Carteret Islands are believed     2     (inhabit) for more than one thousand years. Few places are as calm, peaceful and beautiful as the seaside here on a calm day. People are very     3     (welcome), gentle, and calm. There’s no phone network, shops, computers, roads, cars, or motorbikes. Food is cooked on open fires. People here live sustainably. They don’t overfish or pollute, making no contribution to the warming of our planet. However, they are feeling the consequences of the climate change.

Now, as the land     4     (swallow) by the rising sea, the islanders are faced with an uncertain future. Storms and high tides wash away homes, destroy vegetable gardens and pollute fresh water supplies. The trees on the island are also being impacted by the saltwater. The beach exists     5     fertile soil once did.     6     the coral and seagrasses die, so do the breeding areas for fish. Many seawalls have been built     7     with little success. The islands have gradually become uninhabitable.

The Carteret islanders are labelled as the world’s first official climate-change refugees, as they are forced to abandon their homelands     8     food shortages, rising sea levels, sinking shorelines, and the dangers of storms and tides. In front of     9     is the choice whether to stay and watch the islands shrink and slowly disappear or try to rebuild their community somewhere else. Yet, the relocation is not a move embraced by most, and some are unhappy living away from their home, and have returned after struggling to adapt. On the other hand, relocation will be a great challenge to the preservation of the identity and culture of the Carteret islanders.

The Carteret Islanders’ story illustrates how small island states and coastal communities fall victim     10     rising sea levels caused by climate change. The Carteret Islanders, with a carbon footprint among the lowest in the world, will be among the first to have to leave their homes because of rising seas caused by emissions from other nations.
