1 . Countless stories have portrayed the deep connection between humans and horses, such as classic literary works Black Beauty and The Chronicles of Narnia. However, the extent to which horses comprehend their human companions remains a mystery. Recent research has shown that horses can distinguish between human expressions of happiness and sadness conveyed through facial movements or vocal tones.

The researchers brought 28 horses into a room one by one, each wearing heart rate monitors as their actions were recorded. The horse faced two screens playing two different videos: one showed a happy person and the other a sad person. A voice was played at the same time, sounding happy or sad.

When the picture and voice didn’t match—for example, if the voice was sad but the picture showed a happy person—the horse seemed puzzled and looked for a longer time, compared to the one that did match, as if it knew something didn’t make sense. “You could imagine that they have a particular box in their mind labeled ‘human sadness’ containing the characteristics of both a sad face and a sad voice, and that when we are sad, they expect what we say to match how we look,” said Doctoral Researcher Océane Liehrmann of the University of Turku, in Finland.

The researchers also saw that horses were more attentive to the screen displaying the happy face. They looked at it more often and for a longer time and their heart rates increased when they heard a happy voice and decreased when they heard a sad voice as well.

It is possible that the horses might have associated happy human expressions with positive memories from their past. Another theory is that seeing a happy person could actually make a horse feel happier—a process known as emotional contagion. “We don’t know whether horses themselves understand what it is to be sad. It is possible that they learn it means something for a human,” said Liehrmann.

1. How did the researchers carry out the experiment?

A．By comparing different horses’ expressions.

B．By monitoring horses’ odd behavior in the lab.

C．By summarizing the characteristics of the horses.

D．By observing horses’ reaction to human emotions.

2. What can we learn from the result of the research?

A．Horses had a preference for happy people.	B．Horses were too nervous about the videos.
C．Horses recognized people’s identity quickly.	D．Horses looked excited at a voice of sadness.

3. What does the underlined word “contagion” probably mean in the last paragraph?

A．Support.

B．Influence.

C．Outbreak.

D．Control.

4. Which of the following is a suitable title for the text?

A．Humans Impact Horses Hugely	B．Horses Dislike Sorrowful People
C．Humans and Horses Interact Closely	D．Horses Know When You are Happy

2 . Concrete has served as the foundation stone of the construction industry for hundreds of years. However, the process of producing concrete is one of the most environmentally unfriendly processes in the world. In the process, not only is carbon dioxide (二氧化碳) released into the air by the energy used to heat the limestone, but the limestone itself also gives out a huge amount of the element.

Luckily, a number of start-ups throughout the world are using creative thinking to make the construction industry a whole lot more friendly for the planet.

A Canadian company called CarbonCure, has found a way to inject (注入) concrete with carbon dioxide itself. Not only does this trap the carbon dioxide into the concrete, keeping it from running away into the atmosphere, but it also creates a super strong material called calcium carbonate, which reduces the total amount of concrete that needs to be used.

California-based Brimstone, is creating carbon-negative concrete by doing away with limestone entirely and instead using silicate rock, a material that does not release carbon dioxide when heated. Instead, the process produces magnesium (镁) , which absorbs carbon dioxide, as the basis for their concrete.

Additionally, researchers at Australia’s RMIT University have recently released a study showing that adding coffee grounds instead of sand to concrete could make it much stronger, reducing both the amount of sand used, as well as the amount of concrete that would need to be used in the final product.

The biggest barrier at this point is convincing members of the industry that the new types of concrete are safe to be used, according to Stacy Smedley, director at a nonprofit focused on decarbonizing construction.

Hopefully these new solutions to the environmental problems of concrete will soon be widely adopted. Given the significant part the construction industry has in releasing carbon dioxide into the atmosphere, great improvements can be made when more environmentally-friendly materials are used.

1. What is the environmental issue associated with traditional concrete production?

A．The high demand for energy.	B．The processing of waste materials.
C．The mass release of carbon dioxide.	D．The use of non-renewable resources.

2. How does CarbonCure deal with the environmental impact of concrete production?

A．By using silicate rock as the basis.	B．By putting carbon dioxide into concrete.
C．By replacing sand with coffee grounds.	D．By absorbing carbon dioxide with magnesium.

3. According to Smedley, what is the major challenge facing these solutions?

A．Difficulty in making profits.	B．Convincing the public of the convenience.
C．Lack of funding for research.	D．Removing the industry members’ safety concerns.

4. What is the author’s purpose in writing the text?

A．To promote an alternative to concrete.	B．To advocate environmental protection.
C．To introduce new ways to produce concrete.	D．To emphasize the significance of creativity.

I was eight years old and wasn’t aware of all the arrangements being made for our journey as a family to London in 1950. My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.

Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.

We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.   

We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.

4 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.

Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.

In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.

Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

5 . Every year, as the surface water temperature off the United States mid-Atlantic coast rises steadily from late spring through the summer, a pocket of uncharacteristically cool and crisp water gets trapped at the bottom of the ocean. Packed with nutrients this thick band of cold water, known as the mid-Atlantic cold pool, is a vital home for shellfish species. Extending at its seasonal peak from Nantucket, Massachusetts, to Cape Hatteras, North Carolina, the cold poll creates a diverse ecosystem ranging from algae(海藻)to fish — and some of the most valuable shellfish fisheries in the United States.

Now, however, two pressures have scientists worrying about whether the cold pool will last. The first is no surprise: climate change. Over the past five decades, climates change has destabilized the cold pool, causing it to warm and shrink. Compared with 1968, the cold pool is now 13℃ warmer and has lost more than one-third of its area.

The second concern is 1ess certain. In 2023, the US federal government approved plans to install(安装)98 wind turbines(涡轮机)off the New Jersey coast, covering an area of more than 300 square kilometers. Yet putting so many turbines to the seafloor could have unexpected consequences for the cold pool. That’s why Travis Miles, a researcher at New Jersey’s Rutgers University, and his colleagues are investigating. So far, Miles and his colleagues can’t definitively say what will happen to the cold pool, saying more research is needed to assess how climate change and offshore wind, together, could affect the cold pool. However, their initial analyses suggest the cold pool should be fine — at least in normal conditions.

New Jersey’s offshore wind plans are strongly opposed mainly by fossil fuel-industry funded efforts. Miles worries that an overabundance of caution or fear of potential impacts, including on the cold pool, might slow down the development of renewable energy. “...it’s quite clear that climate change is far more damaging than installing wind farms,” he says. “I don’t think any scientist would argue with that.”

1. What do we know about the mid-Atlantic cold pool?

A．It forms in early spring.	B．It’s a band of cold near-bottom water.
C．It serves as a habitat of most sea species.	D．It extends from Nantucket to New Jersey.

2. What does the underlined word “shrink” in paragraph 2 mean?

A．Break down.

B．Get polluted.

C．Dry up.

D．Become smaller.

3. Miles’ attitude toward installing wind farms can be described as ______.

A．supportive

B．dismissive

C．overcautious

D．skeptical

4. What is the best title for the text?

A．The Cold Pool Plays a Role on species

B．Opinions Divide on Offshore Wind Farms

C．Scientists Eye Potential Risks to the Cold Pool

D．Renewable Energy Helps to Race Against Climate Change

6 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.

In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.

The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.

They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.

So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

1. What does the author describe in paragraph 1?

A．An amazing autumn game.	B．A common sight in gardens.
C．A hot attraction in the north.	D．An extreme weather event.

2. What is the received wisdom?

A．Fallen leaves need not be cleared.

B．Fallen leaves protect shorter grass.

C．Fallen leaves block photosynthesis.

D．Fallen leaves are hard to break down.

A．it ruins city image	B．it breaks gardening rules
C．it affects local economy	D．it causes ecological damage

4. What’s the author’s attitude to Wisconsin University’s study?

A．Doubtful.

B．Positive.

Tomatoes: The Real Magical Fruit

“Fresh tomato plants! Straight out of the ground! 50 cents each!” I shouted in the school hall. In my hands, I carried a shoebox with little tomato plants. Their homes were plastic bottles, without the top half. Most people ignored my product, but some handed me 50 cents and picked out a 2-week-old baby tomato plant.

About a month before this, I started gardening. I pulled up grass in my little garden for several days in a row. Satisfied with my work, I continued to the second step — begging my dad to take me to the supermarket. He agreed!

When my dad turned off the engine and opened the door, I practically skipped inside the supermarket. We headed straight for the garden center. I picked up planters, seeds and dirt. My dad helped and showed me the best dirt and tomato plant types to get. We got to the register, and my dad, knowing what would happen, helped me pay.

As soon as I got home, I began to plant them in my garden. The following days witnessed my visits to the garden and my parents were amazed by my devotion to my new-found love.

Then was the part where I met my problem — I planted too many tomato seeds. I realized this all too late, about 10 days later when they all started sprouting (发芽) up and I counted 45 tomato plants. A few days went by and then I ended up with 85 tomato plants.

I did what all high schoolers would do when they messed up — I asked people around. I even got a notebook to write down their suggestions. Sadly, I got the same answer from most people, “Just let them die.” WHAT?! Let my beautiful plants die? They had so much potential! They could make 20 — 30 tomatoes per plant! We were talking about the possibility of around 2,550 tomatoes!

9 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.

Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.

By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”

Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.

1. What initially caused Burrows to pick up roadside garbage?

A．He wanted to kill time by picking up litter.

B．He aimed to raise fund for soldiers with PTSD.

C．He felt annoyed to see the increasing rubbish.

D．He received the assignment from his employer.

2. How did collecting roadside garbage affect Burrows’ PTSD?

A．It resulted in his embarrassment.	B．It increased his sense of isolation.
C．It worsened his stress and anxiety.	D．It brought him comfort and relief.

3. What concerned Burrows when he started Truckers Cleaning Up Britain?

A．He feared being teased for his action.

B．He was lacking in advanced cleanup tools.

C．He was unsure about the group’s development.

D．He worried about the local council’s disapproval.

4. What can be a suitable title for the text?

A．A Joyful Volunteer Experience	B．A Trucker’s Cleanup Initiative
C．A Fighting Hero against PTSD	D．A Platform for Environmentalists

10 . After spending 589 days picking up litter or rubbish at one of Los Angeles County’s most popular hiking spots, 20-year-old Edgar McGregor says the park is clean of waste.

McGregor’s journey was sparked by an Olympic dream. When he learned Los Angeles would be hosting the 2028 summer games, he worried that its national forest with litter everywhere would become a “global embarrassment” and took it upon himself to start cleaning.

McGregor decided to start with Eaton Canyon, the closest of the Angeles National Forest parks to where he lives. It has miles of crisscrossing trails, popular waterfalls, eleven storm drains, seven homeless encampments, five entrances, four parking lots and more than two miles of streambeds. At the beginning, he thought that cleaning the park would take 10 to 20 days. It took 589 days.

On his largest solo cleanup day, McGregor spent 300 minutes clearing an area less than one acre in size. He filled a previously empty dumpster (垃圾箱) with more than 1,000 pounds of trash. He ventured out in extreme weather, including during the state’s record heat wave in September, after a January snowstorm, and even while the other side of the park was actively on fire.!

After months of park cleanliness, McGregor noticed several weeks ago that he was running out of locations to clean-even the spots that were usually reliable sources of litter were mostly empty.

“Not worrying about litterbugs and simply immersing myself in this work has made me more excited than ever to go out every single day and pick up,” McGregor said “There is nothing more satisfying than seeing brand new animals return to your park after months of cleaning up. I highly encourage anyone with any spare time to give this mission a shot. Your parks need you.”

1. Why did McGregor decide to pick up trash in Los Angeles?

A．To raise money for wildlife there.

B．To improve its global image.

C．To qualify it for the Olympic Games.

D．To make good use of the waste.

2. What is paragraph 3 mainly about?

A．The route of the cleanup.

B．The park’s recycling system.

C．The challenges of the cleanup.

D．The popularity of Eaton Canyon.

3. What does McGregor probably think of his work?

A．Demanding.	B．Disturbing.
C．Discouraging.	D．Rewarding.

4. What can we learn from McGregor’s story?

A．Nothing is impossible to a willing heart.

B．A man can be destroyed but not defeated.

C．The secret of getting ahead is getting started.

D．Life is what happens to you while you’re busy making other plans.
