1 . 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.”

2 . 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.

3 . The Man Who Ate his Boots is a fascinating account of expeditions that went wrong. The book examines the 19th century search for a route to Asia by way of the Northwest Passage through the Arctic Ocean. Author Anthony Brandt describes the many attempts by both land and sea that ended in failure and tragedy, including the 1845 expedition led by Sir John Franklin. Brandt shows how these brave, yet sometimes foolish, explorers could have avoided starvation, frostbite, and even death if they had copied the survival techniques of the local Inuit people. Some of the more surprising details the book reveals include:

IGLOOS The explorers, despite repeatedly watching the Inuit build igloos, insisted on using canvas tents. Tents freeze in sub-zero temperatures and give little protection to anyone inside them. If they had learned to build igloos, the explorers would have been warm even in the worst Arctic weather.

SEALSKIN If the explorers had worn sealskin and furs like the Inuit, they wouldn’t have suffered from the frostbite that was common among them, but rare among the Inuit.

DOG TEAMS Why didn’t the British use dog teams to pull their sleds? Pulling sleds themselves was a tradition among many explorers right into the early 20th century. It cost Scott and his men their lives on their return from the South Pole in 1912.

The British did get something right, however, when Captain Edward Parry grew salad vegetables in boxes on board his ship. It was known that fresh vegetables and fresh meat prevented scurvy (坏血病)，although at that time the reason for this (vitamin C) had not been discovered. Parry’s men wouldn’t have been as healthy if they hadn’t eaten the salads.

1. In The Man Who Ate his Boots’ the author mainly ________.

A．introduces some foolish explorers

B．focuses on some unsuccessful expeditions

C．analyzes the Inuit people’s survival techniques

D．explores the advances in equipment used for expeditions

2. According to Anthony Brandt, what should the explorers have done?

A．They should have learned more about how seals survived in cold water.

B．They should have set up more canvas tents to keep themselves warm.

C．They should have helped the Inuit people build igloos.

D．They should have used dogs to pull the sleds for them.

3. It can be inferred from the passage that________.

A．Edward Parry found a way to prevent scurvy by accident

B．Edward Parry’s successful voyage was a rare case at that time

C．Edward Parry was the first captain that grew salad vegetables on board

D．Edward Parry’s men could have been more healthy if they took vitamin C

Is rental fashion the future?

With a cost-of-living crisis and climate awareness sitting heavily at the forefront of our minds, many of us are having to make choices about what we    1    . Fashion is one of them. As of 2021, UK households    2    approximately 57.3 billion British pounds on clothing, significantly contributing to the very real effects of climate change that can be felt around the world.

Even the fastest of fashion retailers are taking note; this summer, BooHoo announced that they will be    3     a returns fee to try and help customers reflect on overshopping habits. Meanwhile, Love Island teamed up with eBay as their official partner for 2022’s series,     4     avoiding their usual tie-ins.

However, there will still be times where a new item feels like a    5    treat: to attend a wedding, to suit the requirements of a job interview, for that much-needed; confidence    6    on a date. For those who love to shop, getting oneself completely out of retail seems a little like a punishment, taking away yet another source of joy during already-undesirable times.

So here comes rental fashion. The set-up is simple. Rent three, five or ten items and swap (替换) every month, with prices starting from £39 a month for a three-item. In the case of any accidents, do not fear     7    and light damages (think broken zips and small stains) are accounted for in the pricing, as is laundry. If you fall in love, there are options to keep certain items longer, or if you’re not in the market for anything new, your     8    can be easily paused or cancelled.

At the end of each cycle, you’ll receive an email reminding you to choose your next box. With a three-item return, items can be returned at a local drop-off point, whilst bigger parcels will be     9    when the team make their next delivery. Think of it a kind of clothing library, where items are rotated in and out of your life instead of     10     dust.

5 . How to save planet earth

Have you ever held a product in your hands and considered the existential weight of your purchase? Beyond each price tag hides a ripple effect. It expands from soil to water ways, grocery aisle to kitchen plates, factories to fulfillment centers and mail slots to landfills. This global impact has become less hidden in the past decade, and ignoring the people downstream from us has grown increasingly difficult.

We’re more aware than ever of the mark our consumption leaves on planet Earth, which now sustains nearly 8 billion people. Somehow, humans are still pumping more than 30 gig a tons of carbon dioxide(CO₂)per year into the atmosphere, despite the mountain of evidence that CO₂ is the top contributor to greenhouse gases causing global warming.     1    We know we need to do better, but we feel helpless and overwhelmed. Let’s call this the eco-essential crisis; it applies on a deeply personal level for most environmentally aware humans, and on a global scale.

Climate journalist and author Tatiana Schlossberg says even a simple trip to the supermarket can feel paralyzing in 2021. “I want to buy the local thing, but it’s not organic. Or, maybe it’s in a plastic box,” she says. In her 2019 book Inconspicuous Consumption, she ventures way beyond the store aisle and into the web of less apparent ways that humans are damaging Earth. For example, your internet use is tied to extensive carbon emissions and energy consumption.     2     The world is more complicated than that.

In fact, being a good citizen on planet Earth with climate concerns, you’ve likely asked or agonized over this question: What should I do?     3     So, we took this question to five people who have immersed their careers, research and writing in the realities of climate science.

One of their most consistent insights may surprise you: Consumer responsibility misses the mark. “One of the major failings of the environmental movement is having everyone focus on these small things that everyone can do.” says Ayana Elizabeth Johnson-a marine biologist and co-host of the podcast How to Save a Planet.     4     There are just more meaningful and long-lasting ways to expend your energy in the climate fight. Most of them involve organization and collective action.

“Individuals join together to collectively have far more power changing the system than they can as individuals,” says Anthony Leiserowitz, director of the Yale Program on Climate Change Communication.

A．That doesn’t mean it’s none of your business.

B．these experts propose other key steps that every human can take toward a better future.

C．Similar challenge apply to use of plastics and consumption of meat and other goods.

D．Part of the challenge with the environmental movement is the astonishing list of things we need to change.

E．The solution to this problem, however, is not for you to stop using the internet, according to Schlossberg.

F．It’s easy to get lost in the storm of supposed answers around social media, the latest data sets and “ego-friendly” marketing campaigns.

6 . Otters, are cute, this no one can deny. They have big eyes, short and flat noses and claws (爪子) like tiny hands. They look even cuter when they wear hats and throw food balls into their mouths as if they were bar snacks, like Takechiyo, a pet otter in Japan. Documenting Takechiyo’s funny behavior has earned his owner nearly 230,000 followers on Instagram, a photo-sharing app.

Takechiyo’s fame reflects a craze across east and South-East Asia for keeping the cute creatures as pets. Enthusiasts in Japan visit cafés where they pay to hug them; Indonesian owners parade their pets around on leads or go swimming with them, then share their pictures online. But these enjoyable photos mask a trade that is doing a lot of damage. Even before they became fashionable companions for humans, Asia’s wild otters faced plenty of threats. Their habitats are disappearing. They have long been hunted for their coats, or killed by farmers who wish to prevent them consuming fishes. The pet trade, which began picking up in the early 2000s but appeared to speed up a few years ago, has made things worse. The numbers of wild Asian small-clawed otters and smooth-coated otters, two species that are in highest demand, have declined by at least 30% in the three decades to 2019.

The international agreement that governs trade in wildlife, known as CITES, now prohibits cross-border trade in these species. But laws banning ownership are often poorly implemented, as in Thailand, or full of holes, as in Indonesia. And the otter-keeping craze has been dramatically improved by the internet, says Vincent Nijman of Oxford Brookes University. In 2017 TRAFFIC, a British charity that monitors the wildlife trade, spent nearly five months looking at Facebook and other social-media sites in five South-East Asian countries. During that time, it found around 1,000 otters advertised for sale online.

In any case, otters do not even make particularly good pets. Every year the Jakarta Animal Aid Network, a charity in Indonesia’s capital, receives some ten otters from people who have struggled to look after them. Faizul Duha, the founder of an Indonesian otter-owners’ group, admits that his two animals emit a “very specific” (read: fishy) smell. They bite humans and chew on furniture. Their scream can be heard blocks away. And their cages need cleaning every two-to-three hours. That is how often they empty their bowels (肠道).

7 . Because of the politics and history of Africa, wild animals there, which are interested in finding food and water not in politics, are in trouble. In the past, there were no borders between African countries, and the animals could travel freely according to the season or the weather. However, in the 19th and 20th centuries, the continent was divided up into colonies and then into nations. Fences were put up along the borders, so the animals could no longer move about freely.

Some countries decided to protect their animals by creating national parks. Kruger National Park, created in South Africa in 1926, was one of the first. By the end of the twentieth century, it had become an important tourist attraction and a home for many kinds of animals. Among these, there were about 9,000 elephants, too many for the space in the park. It was not possible to let any elephants leave the park, however. They would be killed by hunters, or they might damage property or hurt people. South African park officials began to look for other solutions to the elephant problem.

As early as 1990, the governments of South Africa and Mozambique had begun talking about forming a new park together. In 1997, Zimbabwe agreed to add some of its land to the park. A new park would combine the Kruger National Park with parks in Mozambique and Zimbabwe. There would be no national border fences within the park, so that elephants and other animals from the crowded Kruger Park could move to areas of Mozambique and Zimbabwe. This new “transfrontier” park would cover 13,150 square miles (35,000 square kilometers). The idea of a transfrontier park interested several international agencies, which gave money and technical assistance to Mozambique to help build its part of the park.

In April 2001, the new park was opened, with new borders and a new name: The Great Limpopo Transfrontier Park. A border gate was opened between Kruger National Park and Mozambique, and seven elephants were allowed through. They were the first of 1,000 elephants that would be transferred to the world’s greatest animal park.

1. The passage begins with________.

A．a common sense	B．a fact
C．a mysteries event	D．a theory

2. Which of the following was a problem facing Kruger National Park?

A．It was not big enough to hold all its elephants.

B．A lot of hunters slipped in to hunt animals.

C．As the first national park in Africa, it was not well designed.

D．Too much tourism did great damage to it.

3. Which of the following can be inferred from the passage about the new park?

A．It is divided into three parts by fences along borders.

B．It is built mainly for elephants rather than other animals.

C．It is located across the border of South Africa and Mozambique.

D．It is the result of a talk between Mozambique and some international agencies.

4. The passage talks mainly about________.

A．how international aid has functioned in Africa

B．how the Kruger National Park will save its elephants

C．how three African countries cooperated to make a new park

D．how many African animals have suffered because of natural disasters

8 . Bringing Mosquitoes Under Control

Every year, hundreds of thousands of people die of mosquito-borne diseases like malaria and dengue fever. Drug treatments are ________, and, despite decades of effort, vaccines have, for many of these diseases, proven to be difficult to develop.

It is better, then, to stop these infections happening in the first place by ________ doing away with the mosquitoes that carry the diseases. CRISPR-Cas9, a new and powerful genetic-engineering process, could help to do just that.

Craig Montell, of the University of California, and his colleagues have used CRISPR to ________ an existing control method called the sterile insect technique (SIT), which involves releasing lots of sterilized (绝育的) males into the wild. Females that mate with these males produce no young. ________ releases can reduce populations dramatically. SIT has been used in North America to eliminate screwworm flies, an agricultural pest.

SIT has been tried on mosquitoes, too, but with less ________. One reason seems to be the side-effects of the procedure. To sterilize them, males are exposed to poisonous chemicals. This works, but it damages them in other ways, too. The result can be sickly individuals that ________ to compete in the mating game with wild mosquitoes.

Montell and his colleagues hoped that CRISPR might offer a(n) ________. Their first step was to look for genes which affect fertility (可繁殖性) in mosquitoes. They began their hunt in fruit flies and ended up focusing on a gene that, when ________, made male fruit flies sterile. The gene was present in a similar form in their target mosquito species, Aedes aegypti, which passes on, among other illnesses, yellow fever, dengue and the Zika virus. Disabling the ________ gene in male Aedes likewise left them infertile. ________, the genetic changes involved did not appear to affect the engineered mosquitoes in any other way. On every measure of ________, they performed as well as wild mosquitoes.

________ the details are not fully understood, once female mosquitoes have mated a few times, they become unwilling to do so again. Mating with an infertile male is, therefore, not only fruitless in itself, but should also leave a female less interested in ________ males.

There is more work to be done before field trials, but having established the ________, Montell is excited to see where the work might lead. That the engineered males leave no young means that there are fewer worries surrounding any ________ consequences which might arise from the release of millions of genetically edited creatures into the environment. And that the target gene is found in both fruit flies and Aedes suggests it is likely to exist in other disease-carrying mosquitoes, too.

9 . French adventurer-scientist Roland Bourdeix has a grand vision for how to preserve a thousand or more genetic varieties of coconut trees. Imagine, as he does, turning dozens or hundreds of remote Pacific islands into coconut sanctuaries. Each island would contain just a few varieties of these trees.

But why? Are coconut trees, the source of oil and newly trendy coconut water, somehow in danger?

Not exactly. At least not for now. There are plenty of coconut palms all over the tropics, and coconut production has been slowly growing. But that masks a potential long-term problem, says Stephan Weise, Deputy Director General for Research at Bioversity International in Rome. Most coconut production comes from a small part of the coconut’s gene pool (基因库). Producers rely on a handful of high-producing varieties or hybrids (杂交品种). Those commercial varieties are slowly overwhelming (压倒)traditional varieties that people in the tropics have grown thousands of years. Those are the storehouse of the coconut’s genetic diversity: All of the colors, shapes, tastes, and survival tools that this species possesses — and may need again someday.

Conserving (保护)such diversity in agricultural crops is a familiar problem, but the situation with coconuts is a little bit different, Weise says.

First of all, scientists can’t yet preserve a particular kind of coconuts in refrigerated “gene banks,” as they do with standard seeds. They can’t dry, freeze, and preserve coconuts for decades. Instead, coconuts have to be preserved as living trees, growing outside.

This leads to the second problem. Coconut varieties growing in the open air often won’t reproduce themselves successfully. Their flowers pick up pollen (花粉)from other trees nearby, which often turn out to be commercial varieties or hybrids. And when that happens, some genes may be lost altogether.

So what’s the secret to preserving these coconuts? For starters, scientists have set up a dozen open-air coconut gene banks. They’re reproducing each variety through careful hand-pollination of the trees. But Weise says that’s expensive and labor-intensive.

This brings us back to Roland Bourdeix’s crazy-sounding idea. The key to preserving coconut biodiversity more cheaply, he thinks, is isolation. And there’s no more isolated place than a lonely Pacific island. Just convince people on one of these islands to plant coconut trees from a single variety, and the problem is practically solved. He’s found several islands where the inhabitants are willing to help turn his vision into reality. One of them is well-known already: The Tetiaroa Atoll in French Polynesia, an idyllic retreat once owned by Marlon Brando.

1. Why is it important to preserve the traditional varieties of coconut?

A．The traditional varieties are more commercial.

B．They can help explain the history of people living in the tropics.

C．They contain genetic diversity.

D．It can help the tourism on remote Pacific islands.

2. How do scientists usually conserve agricultural crops?

A．They freeze them.	B．They hand-pollinate them.
C．They grow them out of labs.	D．They mix them with other breeds.

3. Why are Pacific islands ideal for the conservation of coconut trees?

A．They are owned by celebrities, which can help promote public awareness of the issue.

B．They are among the most isolated places in the world.

C．The inhabitants on the islands are innocent enough to be deceived.

D．The labor on those islands is cheaper.

4. The best title for the article can be _________.

A．A Crazy Gardener

B．Remote Islands for Preserving Coconut Genes

C．Advantages of Traditional Coconut Trees

D．Loss of Coconut Genes

Throughout history, people have fought bitter wars over political ideology, national sovereignty and religious expression. How much more     1     will these conflicts be when people fight over the Earth’s most indispensable resource water? We may find out in the not-too-distant future if projections about the     2     of water in the Middle East and other regions prove correct.

Less than three percent of the planet’s     3     is fresh water, and almost two-thirds of this amount is     4     in ice caps, glaciers, and underground aquifers too deep or too remote to access. In her book, Pillars of Sand-Can the Irrigation Miracle Last, Sandra Postel outlines three forces that     5     tension and conflict over freshwater. Using up the water “resource pie”. In India, the world’s second-most populous nation, with over 1 billion inhabitants, the rate of groundwater     6     is twice that of recharge, a deficit higher than in any other country. Although water is a renewable resource, it is not a(n)     7     one. The freshwater available today for more than 6 billion people is no greater than it was 2,000 years ago, when global population was approximately 200 million. (The current U.S. population is 287 million.)

Global     8     accounts for about 70% of all freshwater use. In five of the world’s most water-stressed, controversial areas the Aral Sea region, the Ganges, the Jordan, the Nileland and Tigris-Euphrates population increases of up to 75% are projected by 2025. With the fastest rate of growth in the world, the population of Palestinian territory will more than     9     over the next generation. Most experts agree that, because of geography, population     10     and politics, water wars are most likely to break out in the Middle East, a region where the amount of available freshwater per capita will decrease by about 50% over the next generation.
