1 . Why do Dogs Roll in the Grass?

If your dog is anything like mine, she loves rolling around in a patch of grass any chance she gets. And it always makes me happy to watch my dog, Nala, have the time of her life.     1    . Is she cooling off? Is she just super happy? What could it be?

To find out why Nala and so many other dogs like to stop, drop and roll, I reached out to Dr. Stephanie Austin, a veterinarian at Bond Vetin New York City, who explained that dogs can roll in the grass for several reasons!     2    

She’s enjoying a smell.     3    . “They are picking up on hundreds of scents that we can’t even comprehend!” Dr. Austin said. “Sometimes they want to enjoy a scent they’ve found in the grass and will roll around in it to do just that.”

She’s covering up her own scent. According to Dr. Austin, there’s another smelly reason why your pup may be rolling around in that patch of grass. “They want to smell like the environment so they don’t scare off their prey,” Dr. Austin said.

She’s cooling off.     4    , that grass may look extra appealing to your dog. It might even be a little wet from a sprinkler—the perfect combo for your dog to cool off.

    5     Your dog may also just be relaxed and having fun—and rolling on her back is away to show it!

She’s scratching an itch. “It’s good to exclude any allergies and make sure your dog isn’t rolling a ton to scratch a constantly itchy back or side, but otherwise, it’s probably normal that she’s having a good time,” Dr. Austin said.

If you notice your dog rolling around in the grass, it’s probably just her having the best time ever.

A．She is stretching

B．She’s having fun

C．If it’s boring for your dog

D．If it’s a particularly hot day

E．But I’ve always wondered why she actually does it

F．Here are some common explanations behind this behavior

G．It’s important to remember how powerful your dog’s nose is

4 . Eradajere Oleita thinks she may have a solution to two of our country’s long-lasting problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than throw your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.

Chip eaters drop off their empty bags from Doritos, Lay’s, and other favorites at two locations in Detroit: a print shop and a clothing store, where Oleita and her volunteer helpers collect them. After they sanitize the chip bags in soapy hot water, they slice them open, lay them flat, and iron them together. They use padding and liners from old coats to line the insides.

It takes about four hours to sew a sleeping bag, and each takes around 150 to 300 chip bags, depending on whether they’ re single-serve or family size. The result is a sleeping bag that is “waterproof, lightweight, and easy to carry around,” Oleita told the Detroit News.

Since its start in 2020, the Chip Bag Project has collected more than 800,000 chip bags and, as of last December, created 110 sleeping bags.

Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita-whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life-and her fellow volunteers. “We are dedicated to making an impact not only socially, but environmentally,” she says.

7 . It has been more than 40 years since anyone spotted a Japanese river otter (水獭). And the once common Tangtze River dolphins have either disappeared or are very rarely seen.     1     But the advancement of technology could mean that the extinction of other species is not a given (必然).

A huge challenge scientists and conservationists encounter is tracking species facing extinction in order to help them.     2    . One example is the Maui dolphin, one of the rarest and most threatened dolphins in the ocean. Familiar with their summer behavior, researchers knew that there were just 54 of these mammals living off the coast of New Zealand.     3    . After four years of developing, testing and fundraising, these scientists received permission to use a drone with AI that tracked the dolphins no matter the season. The result was the extension of a marine safety place to protect their habitat.

    4    , AI is being used to enhance traditional methods of preventing hunting. Cameras record any boats that try to enter the park on Lake Itezhi-Tezhi, an illegal entry point. AI immediately detects this activity and alerts park rangers, who deal with the illegal hunters.

In Brazil, AI quickly analyzed over 150, 000 satellite images, revealing that the world’s largest tropical wetlands lost 74 percent of its surface water.     5    

The use of AI has helped to accelerate action and increase conservationists’ ability to protect the natural world for generations to come.

A．Give animals on the edge of extinction a fighting chance to survive

B．In Zambia’s Kafue National Park, home to more than 6, 000 elephants

C．Not until that revelation (揭露) were authorities aware of how desperate the situation was

D．Saving them was challenging because their whereabouts (行踪) were relatively unknown

E．These are just a few of the species that have been listed as extinct or locally extinct in recent years

F．However, because of weather conditions, researchers knew next to nothing about their winter behavior

G．This is where AI has brought about a revolution in the way data on these species is collected and analyzed

10 . Working at a commercial bank in New York City in the mid-2010s, Anna Sacks sensed a lack of meaning in her life. She wanted to do something more fulfilling.

Some people seeking meaning might read a self-help book, or perhaps volunteer a few hours a week. Sacks packed up her life and moved to Connecticut for three months to participate in Adamah, a farming program that focuses on sustainable living and growing sustainable food. Returning to New York, Sacks carried with her a newfound purpose and a set of skills to turn her dreams into reality.

“One of the things that really stuck with me from Adamah was how little waste they produced and how they handled the waste they did have, mostly through composting,” she says. “And I just thought, ‘Why aren’t we doing that here? What is actually in all those bags and recycling bins at the roadsides?’”

The Adamah program opened Sacks’s eyes to the damage consumer culture is doing and the need to find solutions. So in 2016, she started working with a food rescue program, and in 2017, she found her true calling—what she calls “trash walking”.

During walks around her neighborhood, Sacks, 31, picked through trash to look for reusable items. Soon her trash walks expanded to include recycling bins in big companies. Surprisingly, she discovered really great stuff—like clothing and food—all of which she documents on Instagram and TikTok.

Under the name The Trash Walker, Sacks quickly gained popularity for her educational, funny, and surprising videos that highlight the problems with consumerism and share information about how to live a more sustainable lifestyle. “The root issue is overproduction, which leads to over-consumption, which leads to a large amount of waste,” she says.

Sacks is one of the most influential climate change activists on social media today. The lesson from her trash walking isn’t just that we need to produce less stuff. It’s that we need to stop throwing perfectly good items in the trash too.

1. What motivated Anna Sacks to get involved in Adamah?

A．A self-help book she read.	B．Her job at a commercial bank.
C．Her desire for a meaningful life.	D．The volunteer experience she had.

2. What did Anna Sacks find impressive about Adamah?

C．To advertise her food rescue program.	D．To handle the damage by consumer culture.

4. What does the author advocate to reduce waste?

A．Raising prices on products.	B．Collecting second-hand items.
