1 . At first, the grains of rice that Ingo Potrykus held in his fingers did not seem at all _________, but inside, these grains were not white, as ordinary rice is, but a very pale yellow — thanks to beta-carotene (胡萝卜素), a building block for vitamin A.

For more than a decade Potrykus had _________ creating a golden rice that could improve the lives of millions of the poorest people in the world, strengthening their eyesight and their _________ disease.

_________ imagining golden rice was one thing and creating one quite another. Year after year, Potrykus and his colleagues ran into one _________ after another until success finally came in the spring of 1999.

At that point, he tackled an even greater challenge. The golden grains _________ pieces of DNA borrowed from bacteria and flowers. It was what some would call Frankenfood, a product of genetic engineering. As such, it _________ a web of hopes and fears.

The debate began the moment genetically engineered crops (GM crops) were first sold in the 1990s, and it has _________ ever since. First to start major protests against biotechnology were European environmentalists and consumer-advocacy groups. They were soon followed by their U.S. counterparts (相对应的人事物).

The hostility is _________. Most of the GM crops __________ so far have been developed to produce a plant that is not harmed by chemicals used to kill weeds (杂草) in the fields. These genetically engineered crops are often sold by the same large, multinational corporations that __________ the weed-killing chemicals that farmers spray on their fields. Consumers have become suspicious (怀疑的).

The benefits did seem small __________ golden rice was developed. It is the first strong example of a GM crop that may __________ not just the farmers who grow it but also the consumers who eat it. In this case, those include at least a million children who die every year because they are weakened by vitamin-A deficiency (缺乏) and an additional 350,000 who go blind.

Many people __________ poverty and hunger look at golden rice and see it as evidence that GM crops can be made to serve the greater public good. They see a critical role for GM crops in feeding the world’s ever-increasing population. As former U.S. President Jimmy Carter put it, “Responsible biotechnology is not the enemy; __________ is.”

A police training academy in Liaoning province is looking for permanent homes for over 50 canines (警犬) that failed the exam to join the official canine team.

The 54 dogs, most of     1     did not qualify to work with the police team, will be auctioned (拍卖) on July 7. The animals were considered unfit for the force     2     not meeting the police’s strict size, strength, personality, or age requirements.

According to the auction’s rules, the starting bid for each dog is 200 yuan but participants     3     first watch a video about their favoured animal before being able to bid (出价) . They are also required to take them home the same day and sign a written commitment     4     (state) that they will follow the local regulations and will not resell the dogs or transfer ownership.

“The owner must treat the adopted dog kindly and feed and manage it properly     5     its natural death, and shoulder full responsibility     6     they fail to fulfill this promise,” the announcement reads.

On its website, details of the animals     7     (download) over 60, 000 times, while the web page has attracted over 150, 000 views.

Following the attention     8     (draw) online, a police officer reminds people     9     (follow) local guidelines on raising these breeds. He says some cities do not allow people to keep large-sized dogs, while     10     require dogs to be micro chipped for “civilized dog-raising”. In short, do not be hot-headed. Think carefully before you bid.

3 . Conservationists go to war over whether humans are the measure of nature’s value. New Conservationists argue such trade-offs are necessary in this human dominated era. And they support “re-wilding”, a concept originally proposed by Soule where people reduce economic growth and withdraw from landscapes, which then return to nature.

New Conservationists believe the withdrawal could happen together with economic growth. The California-based Breakthrough Institute believes in a future where most people live in cities and rely less on natural resources for economic growth.

They would get food from industrial agriculture, including genetically modified foods, desalination intensified meat production and aquaculture (水产养殖), all of which have a smaller land footprint. And they would get their energy from renewables and natural gas.

Driving these profound shifts would be greater efficiency of production, where more products could be manufactured from fewer inputs. And some unsustainable commodities would be replaced in the market by other, greener ones-natural gas for coal, for instance, explained Michael Heisenberg., president of the Breakthrough Institute. Nature would, in essence, be decoupled from the economy.

And then he added a warning: “We are not suggesting decoupling as the pattern to save the world, or that it solves all the problems.”

Cynics (悲观者) may say all this sounds too utopian, but Breakthrough maintains the world is already on this path toward decoupling. Nowhere is this more evident than in the United Sates, according to Iddo Wernick, a research scholar at the Rockefeller University, who has examined the nation’s use of 100 main commodities.

Wernick and his colleagues looked at data carefully from the U.S. Geological Survey National Minerals Information Center, which keeps a record of commodities used from 1900 through the present day. They found that the use of 36 commodities (sand, iron ore, cotton etc.) in the U. S. Economy had peaked.

Another 53 commodities (nitrogen, timber, beef, etc.) are being used more efficiently per dollar value of gross domestic product than in the pre-1970s era. Their use would peak soon, Wernick said.

Only 11 commodities (industrial diamond, indium, chicken, etc.) are increasing in use (Greenwire, Nov. 6), and most of these are employed by industries in small quantities to improve systems processes. Chicken use is rising because people are eating less beef, a desirable development since poultry cultivation has a smaller environmental footprint.

The numbers show the United States has not intensified resource consumption since the 1970s even while increasing its GDP and population, said Jesse Ausubel of the Rockefeller University.

“It seems like the 20th-century expectation we had, we were always assuming the future involved greater consumption of resources,” Ausubel said. “But what we are seeing in the developed countries is, of course, peaks.”

“It was a wave of water,” says Oulimata Sambe. She points out the still-sodden(湿透的) armchairs, muddy wardrobe and the water stain a metre and a half up the wall in her small house in Ngor, a fishing village within Dakar, the capital of Senegal. “I had two grandkids on my bed, I had to     1     them out of the window,” she adds. Not faraway, underpasses on Dakar’s scenic corniche(滨海路) became car-    2     lakes. Just weeks earlier another downpour had turned quiet streets in Dakar into raging rivers and collapsed a section of motorway.

    3     events regularly occur across the region. Recent flooding and landslides also killed eight people in Freetown, the capital of Sierra Leone. In June flooding killed 12 people in Abidjan, the commercial capital of Ivory Coast. Floods in Lagos, Nigeria’s commercial capital,     4     another seven lives. Even when they are not deadly, city floods ruin lives and livelihoods. Storm water recently flooded the biggest textile(纺织业) market in Kano, a city in northern Nigeria, destroying hundreds of thousands of dollars’ worth of     5    .

Unusually heavy rains have become     6     more common over the past 30 years, leaving huge numbers of people at risk. In places this is partly because of deforestation. A recent study by Christopher Taylor of the UK Centre for Ecology and Hydrology, a research institute, and his coauthors found that afternoon     7     in deforested parts of coastal west Africa happen twice as often compared with 30 years ago. Their frequency went up by only about a third in places that kept their forests.

Yet     8     flooding of cities in west Africa is not only caused by heavier rain. Unplanned urbanization is also to blame. As cities have grown, builders have thrown up concrete walls with little     9     about providing drainage, making it harder for water to find a clear path to the sea. As ever larger areas have been paved over, there has been less exposed soil into which water can gently     10     away. And as cites get more packed with new arrivals, their few functioning drains get overwhelmed or clogged.

5 . 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.

This past July was the hottest recorded month in human history. Heat waves smashed temperature records worldwide and even brought summer temperatures to Chile and Argentina during the Southern Hemisphere’s winter. It’s more than just a matter of sweaty discomfort. In the U.S. alone, it kills more people each year than floods, tornadoes and hurricanes combined. As climate change worsens, access to     1     cooled spaces is rapidly becoming a health necessity.

Yet standard air-conditioning systems have     2     us in a vicious cycle: the hotter it is, the more people use the AC—and the more energy is used as a result. Nicole Miranda, an engineer researching sustainable cooling at the University of Oxford says: “it’s not only a vicious cycle, but it’s a(n)     3     one.” According to 2018 data from the International Energy Agency (IEA), the worldwide annual energy demand from cooling is     4     to more than triple by 2050.

It’s becoming increasingly clear that humans cannot outrun climate change with the same air-conditioning technology we’ve been using. One well-known problem with current AC systems is their reliance on refrigerant     5    , many of which are potential greenhouse gases. About 80 percent of a standard AC unit’s climate-warming emissions currently come from the energy used to     6     it, says Nihar Shah, director of the Global Cooling Efficiency Program at Lawrence Berkeley National Laboratory.

Standard air-conditioning systems     7     cool and dehumidify through a relatively inefficient mechanism: in order to condense water out of the air, they overcool that air past the point of comfort. Many new designs therefore separate the dehumidification and cooling processes, which avoids the need to overcool.

Even with some of the best technologies available, the gains in     8     alone might not be enough to offset the widely expected increase in air-conditioning use. It will not work to simply replace every     9     air conditioner with a better model and call it a day. Instead, a truly cooler future will have to     10     other strategies that rely on urban planning and building design to minimize the need for cooling in the first place.

American authorities arrested Masphal Kry, an official in Cambodia’s forestry administration, last November when he was heading to an international meeting about trade regulations for endangered species in Panama. Prosecutors accused him of conspiring with a smuggling ring. The contraband (违禁品): monkeys,     1     long-tailed macaques. His     2     allegedly grabbed wild macaques in Cambodia’s national parks and bribed officials to label them as captive-bred. Fake papers allowed Vanny Bio Research, a Cambodian pharma company, to ship these unfortunate primates (灵长类动物) to America for use in research. Mr Kry is facing trial in Florida’s Southern District Court. The federal government funds seven National Primate Research Centres (NPRCs), which     3     in total around 20,000 primates, not only macaques but also baboons and marmosets. These centres then     4     primates to labs across America. NPRCs have fulfilled only a third of requests for untested-on macaques in 2021 and prices have soared. Before the covid-19 pandemic a rhesus macaque cost $8,000; by 2022 they had     5     $24,000. Another species, long-tail macaques, is probably per pound currently the most expensive     6     wildlife, says Lisa Jones-Engel, a science adviser at PETA, an animal-rights group.

Getting lab monkeys from abroad became harder during the pandemic. Chinese authorities banned the export of all primates in early 2020. The Chinese government wanted to     7     the country’s wildlife trade, which is thought to encourage the     8     of pathogens—like sars-cov-2—from animals to humans.

That forced American companies to rely on less     9     South-East Asian suppliers. Many scientists believe poaching is prevalent across Cambodia. In February, the Department of Justice subpoenaed Charles River over 1,000 juvenile macaques the pharmaceutical company had bought from Cambodia; the DoJ suspected they were     10     in the wild then exported. These primates are now in Texas and Maryland but also in dilemma: they cannot be tested on, nor can they be flown back to Cambodia.

9 . 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.”

The illegal ivory trade (象牙贸易) has been a major problem in Africa for decades. Poachers (偷猎者) and hunters have killed hundreds of thousands of elephants to obtain this precious material. Now the areas in which they do it are taking action. The International Union for Conservation (保护) of Nature (IUCN) announced on Dec 3 that key states     1     poaching takes place have made a promise to stop the ivory trade and protect Africa’s elephants.

Recently, top officials and experts from 30 states met to discuss how to protect Africa elephants. The conference,     2     (organize) by the IUCN and the government of Botswana, was held in Gaborone, Botswana’s capital city.

In     3    1980s, as many as 1 million elephants across Africa were killed for ivory. The ivory     4     (use) to make jewelry and other items. This continued until 1989,     5     the convention (大会) on International Trade in Species voted to ban all trade in ivory. Then, elephants’ population slowly began to increase.

According to the IUCN, 2011 saw the highest levels of poaching and illegal ivory trading in at least 16 years. Around 25,000 elephants were killed in Africa that year. “With an estimated 22,000 elephants illegally     6     (kill) in 2012, we continue to face a critical situation,” said John E. Scanlon, CITES Secretary- General.

At the meeting, key Africa states where elephants make     7     home agreed to develop a “zero-tolerance approach” to poaching. The deal calls for tough sentences for poachers and hunters, and increased cooperation between states where poaching and hunting is a big problem. All participants at the conference agreed to sign the deal. With these states     8     (come) together, there may be hope for elephants.
