1 . Cows produce much methane, the world’s second worst greenhouse gas, as they breakdown the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to their food.
Recently, the researchers from the University of California studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to know the amount of the methane the cows were giving off. They added a small amount of seaweed to the cows’ food.
The consequences were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given. Even the worst-polluting cows produced 33%less methane. Over the five months, the scientists didn’t see any signs that the cows’ stomachs were getting used to the seaweed and starting to produce more methane again. What’s more, the cows that were fed seaweed gained just as much weight as the other cows.
But there are still some big problems with the idea of feeding cows seaweed. For one thing, there’s not adequate seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed. A bigger problem is that for most of their lives, cows live in the fields, where they eat grass. That means there’s no chance to feed them seaweed every day.
Still, as the study shows, something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.

3 . In the rich countries of the West, the electric vehicle revolution is well underway. Climate-conscious consumers drive Teslas or Polestars for reasons of morality and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.
Yet a glance under the hood (引擎盖) of these vehicles reveals a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries, containing almost 300 pounds of lead in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leak into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable but deadly business.
Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an extraordinary scale. The numerous ways lead enters air, water, soil, and homes across the developing world — and the enormous damage it does to human health, wealth, and welfare — causes one of the biggest environmental crises in the world yet receives little attention.
The World Bank estimates that lead kills 5. 5 million people per year, which would make it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is extraordinary, as is its contribution to global inequality — our research on the cognitive effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.
But unlike many challenges faced by developing countries, lead poisoning is a problem that is fixable with some attention and a relatively modest financial investment. Better monitoring, research, and rules can help protect children all over the world from the dreadful effects of lead poisoning and reduce the massive global costs it brings.

4 . At one time or another, we have all wished that our animals could speak to us. But our pets do use another form of communication to tell us what they are thinking — body language. Sometimes this form of communication is easy to understand, but in some instances it can be much more complex.
Animals communicate in a variety of ways using their ears, eyes, mouth, tail, degree of muscle tension and posture. When figuring out what an animal is trying to say to us, we have to look at their overall behavior as well as what the different parts of their body are doing. We also need to consider their environment and what may be causing them to act as they are.
A wagging (摇动的) tail, for example, doesn’t always mean a happy dog. If the dog’s tail is wagging at the same time that their body is loose and their owner has just gotten home, it’s safe to assume that this is a happy dog. If the dog’s tail is between their legs and wagging while their body is bending low, ears are pulled back and they are licking their lips, this dog is more anxious and fearful. Our pets’ body language doesn’t just send us messages; our own body language sends them messages, too. It’s important to avoid staring directly at an animal or approaching them head-on — they can interpret these actions as threatening. It’s best to approach them sideways and to use your peripheral vision to look at them. Instead of leaning over an animal or reaching out toward them — which can also be seen as threatening — let them approach you when they’re comfortable.
While animals can’t speak to us using our language, they do communicate with us constantly through their body language — it’s up to us to pay attention and listen to what they’re telling us!

| B．People can understand it easily and clearly. |
| C．It occurs when animals communicate with humans. |
| D．People can respond to the needs of animals through it. |
| A．Straight. | B．Surrounding. | C．Tough. | D．Unique. |

| B．Difference Between Various Body Language |

As The Jungle Book song Bear Necessities goes, “forget about your worries and your conflict” can be a little bit difficult when you find yourself face to face with a real bear.
Bears are common in the Northern Hemisphere. As human habitats stretch toward the wilderness, more and more animals cross their paths with those of humans. This can lead to dangerous encounters especially when precautions are not in place. In these situations, keeping your distance is still the best advice.
According to the National Park Service, one should also remain calm as bears, more often than not, are not really willing to attack you. Once in a standoff (对峙), avoid making sudden moves or loud noises as these can trigger aggression. 7-year-old Huxley did exactly what he was told when he encountered a massive bear.
It was a Sunny morning. Huxley was wandering on his way home when a big hulking (笨重的) figure emerges from behind him. A hurried glance backward, he knew it was a black bear. The bear approached cautiously at first, probably sizing up the figure in front of him. A second later, perhaps judging that Huxley was no match for it, the bear burst into a full sprint (冲刺) and ran its way toward the boy.
At first, Huxley was really frightened. However, he knew it was impossible to run or fight with the big beast. In the moment of crisis, he remembered his mother reminds him regularly about these possible encounters. She tells him that if Huxley finds himself face to face with a bear and there are no adults around, he should remain calm.
Huxley calmed down at thinking of this. He stared at the bear down without any movement. This might have been the reason why the young bear stopped dead in its tracks. They faced each other motionless, and there was only a foot distance between them.

8 . Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says, “I like to see what’s on the other side of the hill.” She has gone almost everywhere to do that.
In 1988, at the age of 50, she became the first woman to travel alone to the North Pole. She pulled her own sled piled with 160 pounds of supplies, and during her trip no one brought her fresh supplies. Accompanied only by her dog Charlie, she survived cold weather and meetings with polar bears. In fact, Charlie saved her life when one of them attacked her. Near the end of her trip, a forceful wind blew away the majority of her supplies. The last week of the trip, she survived on a handful of nuts and a little water each day.
Helen goes to challenging places not only for adventure, but also for education. Before her Arctic journey, she started a website called Adventure Classroom. On the site, she shares her adventures in order to motivate (激发) students. She explains, “Although kids often see the world in a negative way, without hope for their future, we work to inspire them to set goals, plan for success and never give up.”
Helen grew up in New Zealand. Her parents were athletes and mountain climbers. Following her parents’ example, she climbed her first mountain at 9. Later, she climbed the highest mountains in North and South America, the former USSR and New Zealand.
In 1996, she took on another challenge — the Sahara Desert. She and her husband, Bill, walked 2,400 miles across it! In 2001, she and Bill traveled on foot from west to east through the Gobi Desert in Mongolia. They hope to travel to Sichuan and Tibet in China to study pandas this year.
Helen plans to continue taking trips. She’ll use her explorations, writing, photography and environmental work to create programs for her Adventure Classroom website. She wants to inspire her students never to stop facing challenges!

9 . It’s been more than 60 years since Jane Goodall started her pioneering work. In 1960, she was chosen to go to what is now Tanzania and study the little-known world of chimpanzees. Since then, Goodall has received many awards and honorary degrees as a world-famous conservationist (自然环境保护主义者). Now, Goodall has received an unusual honor. She is becoming a toy — a Barbie doll.
Goodall may not have expected to become a Barbie at 88 years old — but it’s not just any doll, it’s made out of recycled plastic. And Barbie is partnering with the Jane Goodall Foundation and its Roots & Shoots program which inspires young people to protect animals and the environment.
“You know, the main message is that every day you live, you make an influence on the planet and you get to choose what sort of influence you make,” Goodall said.
“There was a little boy of 7 in Burundi, and I had given a talk to the school and he came up to me and said, ‘If I pick out a piece of trash every day, it will make a difference, won’t it?’ And I said, ‘Yes it will. And suppose you persuade (劝说) 10 of your friends to pick up a piece of rubbish every day.’ He said, ‘Oh, that would really make a difference and then they could all get 10 of their friends, couldn’t they?’ Goodall said, “So, that’s it. The cumulative (积累的) effect of small actions can lead to big change.”
She’s been inspiring young people for decades, but now, newer generations will get to know Jane Goodall. “I sincerely hope that it will help to create more interest in the natural world,” she said about the Barbie. “Because hopefully, you know, they’ll learn more about me through the doll. And that will get them interested. It doesn’t really matter if they have a career in conservation, as long as they pay attention to conservation in their daily lives.”

It was a chilly autumn evening. Sarah, a tired businesswoman, left her workplace and drove home. When she turned a corner, she spotted a puppy in the middle of the road. The dog was muddy and trembling. His eyes held a glimmer of both hope and despair. Sarah couldn’t ignore the poor puppy. Approaching him cautiously, she coaxed (哄) him and brought him home.
Over the next few days, Sarah tried her best to look for the dog’s owner, but in vain. It seemed that the dog had been abandoned, with no collar or tags to identify its owner.
She determined to take care of the dog, which she named Max. She kept him in the backyard, feeding him, providing water and watching him chase his tail in the yard. The puppy trusted in her slowly with Sarah’s gentle care and patience. Sarah had a happy feeling she never had before.
As days passed, Sarah became more comfortable with Max’s presence. When she was working, Max would sit calmly by her side. When she woke up in the morning, Max would sit near her bed with a playful bark, demanding his daily walk. The early morning air was cool, and the rising sun cast a warm glow on them. Sarah realized that Max had been a great comfort to her.
As days turned into weeks, Sarah grew more attached to Max. She found herself looking forward to coming home every day, excited to see her furry friend waiting at the door. Then, she would lovingly prepare Max delicious meals. His eyes, once filled with sadness, now sparkled with gratitude. He would eagerly follow her around the house wherever she went. Max became more than just a pet; he became a loyal friend and a source of happiness for Sarah, who had discovered a newfound balance between her career and personal life. They became inseparable.
One evening, as Sarah and Max were out for their regular evening walk, something unexpected happened. A social media post attracted her attention. A lady named Emma was anxiously looking for her missing dog, Buddy.
