1 . Many of the world’s islands were previously unexplored places, but over time, people have come to these places with far-reaching effects, including deforestation, over-hunting and the introduction of invasive species. _______, most of the bird species disappeared.

While the death of many birds since the 1500s has been _______, our knowledge of the fate of species before this relies on fossils (化石), and these records are limited because birds’ lightweight bones are _______ over time. This conceals the true _______ of global extinctions.

Researchers now believe 1,430 bird species — almost 12 per cent — have died out over modern human history since around 130,000 years ago, with the vast majority of them becoming extinct directly or indirectly _______ human activity.

The study, led by the UK Centre for Ecology & Hydrology (UKCEH) and published in Nature Communications, used statistical modelling to _______ the undiscovered bird extinctions.

Lead author Dr Rob Cooke, an ecological modeler at UKCEH, says:“Our study demonstrates there has been a far higher _______ impact on diversity than previously recognized. Humans quickly destroyed bird populations through habitat loss, over-exploitation, and the introduction of rats, pigs, and dogs, which attacked the birds’ nests, and _______ with birds for food. We show that many species became extinct before written records and left no _______, lost from history.”

Dr Søren Faurby of the University of Gothenburg, a co-author of the study, adds: “These historic extinctions have had a major impact on the current biodiversity crisis. The world may not only have lost many fascinating birds but also their varied ________ roles, which are likely to have included key functions such as pollination (授粉). This will have had knock-on effects on ecosystems, so, ________ bird extinctions, we will have lost a lot of plants and animals that ________ these species for survival.”

Observations and fossils show 640 bird species have been driven extinct — 90 per cent of these on islands ________ by people. These ________ from the iconic (标志性的) Dodo of Mauritius to the Great Auk of the North Atlantic to the lesser-known Saint Helena Giant Hoopoe. But the researchers estimate there have been further 790 unknown extinctions, meaning a total of 1,430 lost species — leaving just under 11,000 today. Therefore, from the perspective of protecting species ________, the protection of birds is an urgent issue for mankind.

2 . The misery of my bike commute in Calgary, Alberta, is the river valley hill. It’s not particularly steep, but at about a mile long, I rarely climbed up without arriving with sweat. Studies have shown the prospect of arriving at work sweaty is one of the biggest _________ to getting would-be bike commuters out of their cars. That’s especially true in a city like Los Angeles, where _________ may face long routes , hills or hot streets with a lack of shade.

“Pedelec”, or pedal electric-assisted bikes like the one I rode, can end that worry. They look and act like traditional bicycles, but their motors make pedaling much easier when required. Sometimes called the most energy-efficient motorized mode of transportation ever built, they’re also incredibly green. The biggest barrier may be the outdated attitude that sees bikes only as a recreational athletic opportunity rather than a practical _________ option.

At a time when cities across North America are struggling to combat crippling traffic and reduce climate emissions, e-bikes have the _________ to ease the both problems. And yet ridership has yet to truly _______.About 152,000 e-bikes were sold last year in the U.S., a figure that would be more than 5 million if Americans used them at the same rate as western Europeans.   

Many of the barriers to e-bike _________in North America are legislative. Patchwork rules treat e-bikes more like mopeds than traditional pedal bikes in some jurisdictions,meaning they are _______from bike lanes and from boarding public transportation.

Few places on the continent, _________, are better poised to break through barriers than California. Legislation was approved last year to encourage e-bike use, by legally differentiating the cycles from mopeds. In an attempt to head off worries about turbocharged machines flying down sidewalks and bike lanes at unsafe speeds, the law classifies bikes into different tiers to _______ lower-speed e-bikes, which top out at 20 mph, from faster-moving “speed pedelecs”, which are restricted from protected bike paths.

Amid these legislative ________, e-bikes have become more accessible to consumer. Finding them in bike shops isn’t as __________ as it once was, and their cost has fallen as the price of lithium-ion batteries has dropped. Today, a decent e-bike, while still __________, is comparable in price to a high-end mountain bike. After years of ____________over mixing pedal and motor power, cycling advocacy organizations also are finally throwing their support behind e-bikes. Dave Snyder, the executive director of the California Bicycle Coalition, __________ the state’s new legislation based partly on the __________that e-bikes help out those who“just can’t ride as far or as fast as they need to”.

3 . Global surface temperatures last month were 2.25 degrees warmer than the 20th century average of 60.1 degrees, breaking previous records, from August 2016, by more than half a degree, according to NOAA researchers. “That to me is a really huge _______ from one record to the next,” said Ellen Bartow, a physical scientist with NOAA’S National Centers for Environmental Information.

The report _______ what millions of people have experienced in recent months, including record-breaking heatwaves that have touched almost every corner of the globe. Asia, Africa, North America and South America had their warmest August on record, as did the Arctic, Europe and Oceania — a region that _______ Australia - had their second-warmest August on record, the report said.

It wasn’t just the land that _______ : August set a record for the highest monthly sea surface temperature abnormally—1.85 degrees above average. The warming oceans _______experiencing its fourth continuous month with the _______ shrinking sea ice, with Antarctica sea ice extent on record. Globally, sea ice extent in August was about 550,000 square miles less than the previous record low, set in August 2019.

“We’ve seen unheard-of warmth in the global ocean, and that’s definitely alarming because its effects _______ beyond just the scope of the ocean,” Bartow-Gillies said. “Not only are you _______ marine habitats, but you’re affecting storm creation, you’re creating more instability in some areas, and you’re creating flooding events in other areas. There’s a whole host of _______ that come along with these warmer ocean surface temperatures that we’re seeing.”

In fact, the report comes after a series of severe natural ________ that span the globe. This week, a Mediterranean storm caused serious flooding in Libya, killing more than 11,000 people. In Canada, wildfires burned through more than 42 million acres of forests this summer, and several are still burning. ________ global warming was not the singular cause of any of these disasters, heating of the Earth continues to ________ the likelihood of extreme weather events and wildfire worldwide.

“The scientific evidence is ________ —we will continue to see more climate records and more intense and frequent extreme weather events impacting society and ecosystems, until we stop ________ greenhouse gases,” read a statement from Samantha Burgess, deputy director of the European Union’s Copernicus Climate Change Service, which also ________ that this summer was the hottest on record.

4 . Sea levels along coastlines in the United States will rise about one foot by 2050, with larger increases on the East and Gulf coasts, according to a comprehensive new report by climate scientists.

Oceans have already risen about one foot in the last century, as climate change melts glaciers (冰川) and ice caps around the world. But the pace is ______ scientists warn, and the next 30 years will see the same amount of sea level rise as the previous 100.

The report gives the most concrete and certain sea level ______ ever published for the U.S. And advances in computer models and real-world information about rising seas make it possible to see the future more ______ than ever.

Sea level rise ______ dramatically for different parts of the U.S. coast. The ocean is not like a bucket of water that rises at the same time as more liquid is ______. Ocean ______ push more water into some areas than others. Ice in different regions melts at different rates. In many parts of the world, sea level rise is ______ because coastal land is sinking.

The new report adds up all those factors to give ______ estimates for different parts of the U.S. The authors predict about a foot and a half of sea level rise for the Gulf Coast by 2050, with particular hot spots from Texas to Mississippi, where exploitation of underground oil, gas and drinking water is causing the land to rapidly _____ into the rising ocean water. There are ______ hot spots in the Mid-Atlantic region, including Annapolis, Md. and Norfolk, Va. Overall, the East Coast is ______ to experience a little more than a foot of sea level rise in the next 30 years.

Sea level rise is happening more ______ on the West Coast, including much of southern and western Alaska, the report finds. The authors predict about six inches of sea level rise by 2050.

William Sweet, a sea level rise expert with the National Oceanic and Atmospheric Administration (NOAA) and one of the authors of the new report, says cities that are not yet flooded should ______ now. Quickening sea level rise may require that humans ______ where and how we build homes, offices, roads and anything else that is better dry than wet. Right now, development in flood-prone (易发洪水的) areas is increasing, despite climate change.

Beyond 2050, the report makes clear that humans have a ______: reduce greenhouse gas emissions and control sea level rise, or keep burning fossil fuels and face oceans that are two, three or even 10 feet higher than today.

5 . The Amazon is warming three times faster than the global average

It is perhaps the most ironic symbol of the life on our planet. The Amazon is the world’s largest and most bio-diverse tropical rainforest and a huge trap for carbon dioxide. The harms of _________ in this vital resource are old news. But now, the time on the clock is running out. It seems that the world’s biggest rainforest is about to turn into the world’s biggest environmental _________. “We are about to collapse,” says Luciana Gati at Brazil’s National Institute for Space Research. “We are in a(n) _________, we need action now.”

Gati has spent years _________ the Amazon from the air. She believes we are as little as five years from a point of no return, where rainforest begins to turn into dry land. It is also the point at which billions of tons of carbon would be _________ into the atmosphere. “It’s a nightmare,” she says.

That nightmare situation is the well-known Amazon _________ point, where the ecosystem can no longer cope with the damage of the forest cutting. Like a domino game, one brick falling will _________ the whole tower to collapse in a heap.

Warnings that this is approaching have now taken on extreme urgency. The rate of deforestation has increased sharply and is fast approaching the theoretical _________. In September, a group of more than 200 experts, including Gatti, released an assessment of the situation. The conclusion: we are on the _________ of disaster.

Scientists first began to seriously worry about a potential Amazon tipping point in about 2000, when some studies warned that a combination of climate change and deforestation could cause the rainforest to __________.

A few years later, a team of Brazilian scientists put numbers on it. They __________ that in central, southern and eastern parts of the Amazon, a loss of 40% of the forest cover from pre-industrial levels, or 3°C warming would reduce rainfall so much that the rest of the forest would die of __________ and turn into a dry land in less than a decade.

The scientists have since __________ that prediction, partly due to the global warming that has happened since 2000. The Amazon is already 1.2°C warmer than it was in pre-industrial times and is warming three times faster than the global __________. At that rate of warming, between 20 and 25% deforestation would be enough to dry up the land and destroy the Amazon completely.

“Either way, we would be wise not to exceed 20%”, says a scientist, “for the commonsense reason that there is no point in __________   the precise point of limit by tipping it.”

6 . In Mumbai, there’s the ceaseless clamor of car homes as drivers edge through traffic. There’s pounding and buzzing from the construction of office towers and apartment blocks. Drumbeats and trumpet melodies spill out from weddings and countless festivals. And it’s all topped off by bellowing (大声吼叫的) street vendors and garbage trucks blasting Bollywood songs. Living in Mumbai requires a huge ______ for noise.

When Sumaira Abdulali began campaigning against noise pollution in India’s financial capital two decades ago, friends, acquaintances and even her lawyers insisted it was ______ . “People told me it’s foolish to even try, because Indians love noise,” she says. “We’re a noisy country.”

But in 2003, Abdulali won a lawsuit seeking to ______ environmental rules that had allowed loud music late into the night during a festival. ______ , the victory led to a ban on loudspeakers within 100 meters of schools, hospitals, courts and places of worship. And she has since won more than a dozen other actions both on her own and via the Awaaz Foundation (awaaz means “noise” in Hindi), which she launched in 2006.

The World Health Organization warns that noise is a top threat to human ______ , affecting not only hearing but also sleep, brain development and cardiovascular health. Abdulali claims Mumbai is the world’s ______ city. A study led by Ritesh Vijay, an expert from India’s National Environmental Engineering Research Institute, did find that noise levels in Mumbai and surrounding areas in 2020 dramatically exceed legal limits.

In recent years, the battle against noise has become increasingly ______ , with Abdulali often facing powerful interests who consider it an inevitable byproduct of growth. With increasing ______ , ever more people are exposed to continuous noise. In a rapidly expanding city such as Mumbai, with a population topping 12 million, demand for housing puts noise rules ______ development plans. Although sound barriers are required for construction projects, they’re expensive, so developers ______ installing them.

Traffic is a tougher problem. Noise on the road can reach 110 decibels (分贝) — a level that can lead to permanent hearing damage after just 15 minutes of exposure, according to the US Centers for Disease Control and Prevention. Luckily, ______ can help in the fight, Vijay says. He suggests devices that measure horn use, which would let officials offer ______ drivers rewards like deductions (扣除) on car insurance. Dynamic signaling, where sensors linked to stoplights detect traffic density, would improve vehicle flow and ______   the urge to resort to horns, he says. Local government also ______ . Mumbai decreed (颁布) India’s first “No-Honking” day in 2008, with police handing out booklets to raise awareness about traffic noise and imposing fines up to 1,000 rupees ($12) on offending motorists.

Far more important is the longer-term impact of the day-to-day noise, so that’s where Vijay believes activists should focus their energy. “In India we celebrate festivals with lots of noise,” he says. “But our ______ noise itself is beyond the allowed limit.”

7 . The Grey’s Anatomy doctors are navigating the patients that have kept them on our screens for some 400 episodes of the show. But in this episode, for the first time, the _______ to the drama is the very real issue of climate change. It’s a relatively rare example of the many kinds of climate-related storylines that are typically missing from _______ TV and film worlds. Social scientists argue that climate is a topic that belongs in many kinds of on-screen stories, not just the _______ climate-disaster thriller.

But can seeing the realities of climate change affecting characters on the screen help us relate _______ to the unfolding climate crisis – to cope better, or even change our behavior?

Non-profit storytelling consultancy Good Energy believes it can. It is among a small but growing number of organizations _______ far more TV and film scripts to _______ climate-related storylines. In April 2022, it released its Good Energy Playbook, a set of guidelines for embedding climate change into any on-screen story. It joins other initiatives in drawing attention to the need for film and TV to _______ the numerous ways climate change leaves its mark on our everyday lives.

The Good Energy Playbook’s suggestions are appropriately wide-ranging: characters with climate anxiety and those fighting against injustice; utopian (乌托邦的) narratives that explore climate solutions; storylines that quietly _______ climate references into their characters’ worlds.

The playbook was created by Good Energy founder Anna Jane Joyner, “It started as a personal _______, where I just got on the phone with as many screenwriters as I could,” she says. She quickly learned that writers wanted to talk about climate, but “didn’t really have the support and toolset to be able to do it”.

Many research studies looked at the impact introducing climate stories had on viewers, and found it prompted greater concern about climate change. It also ________ people’s understanding of it and made them more likely to take action to reduce their emissions. ________, science tells us that stories have a power that hard facts often don’t. Research has long established that the human brain finds it easier to understand and remember information delivered as a ________, and has even found that stories can influence behavior.

Climate stories, then, seem like a pretty good idea. But these sorts of narratives have been few and far between. Julie Doyle, professor of media at the University of Brighton in the UK, says climate change has ________ for years to get into any form of fictional film or TV representation. “There’s been a silence around it,” she says.

It’s time to break the climate silence, says Doyle. “Mainstream media has tended to follow rather than lead, and it would be great if mainstream media could lead this.” Day-to-day mentions of climate change in media are especially important because, while blockbuster climate films can have a positive impact on awareness and action, the effect is sadly __________. People can feel inspired to take action in the moment, but the feeling __________ in a matter of weeks.

8 . Climate experts have warned about the many ways a warming planet can negatively affect human health. ________ global temperatures are predicted to increase by 1.5℃ by the 2030s, that risk is becoming increasingly real.

One long-held prediction that appears to be coming true — according to the results of a study recently published in Nature Scientific Reports — is how climate change might enhance ________ of bacteria that thrive and spread through warm sea waters and cause an infection with a particularly high ________ rate.

Vibrio vulnificus (创伤弧菌) flourishes in salty or brackish waters above 68℉. Infections are currently rare in the U.S., but that’s likely to change. Using 30 years of data on infections, scientists at the University of East Anglia in the U.K. found that Vibrio vulnificusis ________ from its historic Gulf Coast range, with more Northern states reporting infections as waters become warmer.

“We’re seeing the core ________ of infections extending to areas that traditionally have very few and very rare cases,” says Elizabeth Archer, a Ph.D. researcher and ________ author of the study. “But these areas are now coming into the main area of infections.”

Based on the latest data on how much the world’s water and air temperatures will rise, the scientists predict that by 2081, Vibrio vulnificus infections could reach every state along the U.S. East Coast. Currently, only about 80 cases are reported in the U.S. each year; by 2081, that could go up to over three-fold, the authors say.

Such a proliferation could have serious health consequences. Vibrio vulnificus kills approximately 20% of the healthy people it infects, and 50% of those with weakened immune systems. There is little evidence that antibiotics can ________ the infection, but doctors may prescribe them in some cases. People can get infected either by eating raw shellfish like oysters or by exposing small ________ to waters where the bacteria live, which can lead to serious skin infections.

Warming sea temperatures aren’t the only reasons behind the rise of Vibrio vulnificus. Hotter air also draws more people to the coasts and bays, bringing them into closer contact with the bacteria.

“The bacteria are part of the natural marine environment, so I don’t think we can ________ it from the environment,” says Archer. “It’s more about mitigating infections by increasing ________ of the risk.”

To alert people to the growing threat, ________ systems are needed to track when concentrations of bacteria start to rise, similar to currently available pollen and pollution alarm.

Vbrio vulnificus is so ________ to temperature changes that concentrations could bloom after even a day of warmer water, so consistent monitoring and alerts are critical, says Iain Lake, professor of environmental epidemiology at University of East Anglia and senior author of the paper.

Lake says the expansion of Vibrio vulnificus is concerning for public health since the bacteria are now invading waters closer to heavily ________ areas, such as New York and Philadelphia. “Everyone can get a Vibrio vulnificus infection,” he says. “But the more ________ there is between warmer waters and people, the more the bacteria can move into populations ________ the elderly and those with other health conditions, who are more vulnerable to infections.”

9 . The part of the environmental movement that draws my firm’s attention is the design of buildings. Today, thousands of people come to ________ building conferences, and the idea that buildings can be good for people and the environment will be increasingly ________ in years to come. Back in 1984 we discovered that most manufactured products for decoration weren’t designed for ________ use. The “energy-efficient” sealed commercial buildings constructed after the 1970s energy crisis ________ indoor air quality problems caused by materials such as paint, wall covering and carpet. So for 20 years, we’ve been looking for ways to make these materials ________   for people and the planet.

Home builders can now use materials, such as green paints, that release significantly ________   amounts of chemical compounds, which people believe don’t ________ the quality of the air.   ________, our basic design strategy is focused not simply on being “less bad” but on creating ________ healthful materials that can be either safely returned to the soil or ________ by industry again and again. For example, the world’s largest carpet manufacturer has already ________ a carpet that is fully and safely recyclable.

Look at it this way: no one ________ to create a building that destroy the planet. But our current industrial systems are basically causing these conditions, whether we like it or not. So   ________ of simply trying to reduce the damage, we are ________ a positive approach. We’re giving people high-quality, healthful products and an opportunity to make choices that have a ________   effect on the world. It is not just the building industry, either. Entire cities are taking these environmentally positive approaches to design, planning and building.

10 . After five long years, it appears California’s drought is finally becoming less severe. _______ a recent string of storms, more than a third of the state has now welcomed healthy precipitation (降水量), and California’s snowpack—a(n) _______ source of water as the year progresses—has reached nearly twice its seasonal average in some parts of the Sierra Nevada. That’s a dramatic improvement over last summer, when literally every inch of the state _______ drought conditions. It’s also welcome news for Californians, who have faced a series of water _______ since Governor Jerry Brown declared a state of emergency in early 2014. Farmers have been forced to spend heavily to maintain production.

The state’s water struggles, _______, are far from over. For one, nobody knows for sure how long these rains will last. Although recent precipitation has been _______—in some places more than 80 inches—the accuracy of storm forecasting remains _______ beyond a week. Californians know this all too well: last year, experts projected a “Godzilla” El Niño that would bring record levels of precipitation. It never _______. “Will six weeks from now be wet?” asks Jeanine Jones, California’s interstate water-resources manager. “The skill in that kind of forecasting is just not there.”

_______, a storm slowdown is a very real possibility—and it could leave California without enough water to make it through the dry summer. ________, when that happens, the state has turned to groundwater stored in natural rock formations deep beneath the earth’s surface. But those ________ remain used up after years of drought; restoring them could take years in some places, says Jones.

The quick inrush of water has also created a(n) ________ balancing act for water managers. Keeping surface reservoirs (水库) filled to the edge protects against the possibility of a sudden dry spell, but it also

________ the risk of flooding if and when future storms hit. To that end, water managers opened the Sacramento Weir floodgates earlier this month to pour reservoir water into nearby fields after ________ showed local water levels would likely continue to rise. That’s a calculation that will be made across the state in the coming months.

For now, though, Jones is focused on planning and ensuring the state’s water supply whatever may happen. “We’re halfway through our wettest season, and conditions have been encouraging,” she says. “I would say we’re ________ optimistic.”
