On a hot September afternoon, Peter and his friend Isabel were on their way to the library. When they passed by Tubman park, Isabel suggested cutting through it to get to the library. As they entered the park, the sight of the swings (秋千) and the merry-go-round brought back a flood of memories of their childhood spent there. But now everything looked so old, sad, and dirty. Litter lay on the ground next to an overflowing trash bin. There were still young schoolchildren playing there but they had to avoid the trash that littered the playground. A little boy told them that the city took the other trash cans away and the remaining one never got emptied often.
As they headed toward the library, the two high school students wrinkled their forehead. In the library, they encountered Mrs. Evans, their kind-hearted fifth-grade teacher, retired yet still passionate. Mrs. Evans listened as Isabel and Peter eagerly explained what they’d seen. Finally, she recommended them to go to the City Hall to voice their concerns.
The next day, Isabel and Peter went into the building of the City Hall but were met with an impatient officer. They were informed that the city couldn’t help with their problem due to a tight budget. Discouraged, they left and turned to Mrs. Evans for help.
Under her guidance, they decided to ask Go Green, a non-profit organization whose goal is to protect the environment, for help. “This group is good at raising money for projects just like yours, ” said Mrs. Evans. She promised to arrange them to present their ideas to Go Green. Hearing this, their face lit up.
Two main tasks remained ahead: researching ways to clean up the park and preparing a convincing presentation. As Isabel was good at researching while Peter always had a talent for speaking, they cooperated quite well. Isabel learned from a science magazine that a new type of trash bin can squeeze the trash down without being emptied often, which saves time, money, and energy. Based on this, Peter practiced his presentation over and over again.

3 . Eradajere Oleita thinks she may have a partial solution for two of our county’s longstanding 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 in 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 clean the chip bags in soapy hot water, they slice then open, lay them fat, and iron them together.
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 Detroil News.
Since its start in 2020, the Chip Bag Project has collected more than 80,000 chip bags and, as of last December, created 110 sleeping bags.
Sure, it would be simpler to raise the money to buy new seeping 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 committed to making an impact not only socially, but environmentally,” she says.
And, of course, there’s the symbolism of salvaging bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental injustice and poverty often go hand in hand. As Oleita told hourdetroit com: “I think it’s time to show connections between all of these issues.”

4 . Wildlife workers in Florida are feeding manatees to keep them from starving.
Manatees are huge sea mammals that can be as long as 4 meters when grown.
But Florida’s manatees have been on the US government’s list of endangered animals since 1967. Most threats to manatees come from humans. One of the biggest problems facing the creatures are boats.
But now manatees are facing a new challenge: they can't get enough to eat. Many of the beds of sea grass that manatees depend upon have been killed by human-caused pollution. Sea grass began to disappear around 2011. Warming seas, combined with polluted water and fertilizers that have washed off of farmlands, have created huge growths of algae on the ocean’s surface.
Last year, 1,101 manatees died from starving.
So last December, wildlife experts came up with a plan to get emergency food to the manatees. They decided to feed them green vegetables like lettuce and cabbage. Long term, Florida is working to help restore sea grass beds. But that will take time.
| A．That was a record. |
| B．They can weigh up to 590 kilograms. |
| C．The feeding station has been very successful. |
| D．With protection, manatees managed to bounce back. |
| E．It blocks the sunlight that allows the sea grass to grow. |
| F．But feeding these massive sea creatures takes a lot of food. |
| G．Research needs to be done to determine what food would be best. |
5 . Saturn (土星) is famous for its lovely rings, but a new study suggests the planet has spent most of its 4.5 billion years without them. That’s because the rings are likely only 10 million to 100million years old, according to a newly published report in the journal Science that’s based on findings from NASA’s Cassini probe (探测器).
Cassini spent some 13 years orbiting Saturn before diving and impacting into its atmosphere. During its final orbits, the spacecraft dove between the planet and its rings. That let scientists measure the gravitational effect of the rings and get a good estimate of the ring material's mass. What they found is that it’s only about 40 percent of the mass of Saturn’s moon Mimas. This small mass suggests that the rings are relatively young.
“There’s no huge amount of massive material hidden in the rings that we can’t see,” says Philip Nicholoson, a planetary scientist,“The rings are almost pure ice.” He says the relative youthfulness of Satum’s ring system is something that scientists have come to suspect only recently. “It was easier to believe that it formed at the same time as Saturn and its satellites did,” Nicholson says. “It’s hard to understand how they could have formed that recently.” It’s possible that the rings are the remains of a comet (彗星) or some other icy object that made a chance encounter with Saturn and got torn up, he says. Or, perhaps one of Saturn’s icy moons got whacked by an impact with a large comet.
Whatever happened, it’s looking more and more likely that Saturn’s splendid rings are a temporary phenomenon that humans are lucky to get to see at all. Previous measurements from Cassini helped show that the rings may be disappearing at a rapid speed, as dusty ice particles (颗粒) get pulled down to Saturn by its gravity. In another 100 million years, Saturn’s most unique feature might be gone.
1. How did scientists estimate the ring material’s mass?| A．By analyzing the age of the rings. |
| B．By timing Cassini’s orbiting Saturn. |
| C．By recording Cassini’s flying speed. |
| D．By measuring the gravitational effect of the rings. |

| C．They came into being when Saturn formed. |
| D．They are a natural phenomenon of all planets. |
| A．Crashed. | B．Separated. | C．Absorbed. | D．Pulled. |
| A．Saturn Put Rings on It Relatively Recently |
| B．How Saturn’s Rings Formed Came to Light Finally |
| C．NASA Detected Icy Object in Saturn’s Rings Recently |
| D．When Saturn’s Rings Will Disappear Is Being Dug into |

8 . Eyes are said to be the window to the soul — but researchers at Google see them as indicators of a person’s health. A study suggests that Google’s computers can predict whether someone is at risk of a heart attack by analyzing a photograph of their retina (视网膜).
The research relied on a convolutional neural network, a type of deep-learning algorithm (算法) that is transforming how biologists analyse images. Google’s approach is part of a wave of new deep-learning applications that are making image processing easier and could even identify overlooked biological phenomena.
The approach took off in the tech sector around 2012, but scientists struggled to apply the networks to biology, in part because of cultural differences between fields. “Take a group of smart biologists and put them in a room of smart computer scientists and they will talk two different languages to each other, and have different mindsets,” says Daphne Koller, chief computing officer at Calico.
However, through years of study, some scientists have seen a shift that has never happened before in how well machine learning can accomplish biological tasks that have to do with imaging. Others are most excited by the idea that analysing images with convolutional neural networks could unknowingly reveal unnoticeable biological phenomena, encouraging biologists to ask questions they might not have considered before.
Such discoveries could help to advance disease research. If deep learning can reveal markers of cancer in an individual cell, it could help to bring about new assumptions about how cancer spreads.
Other machine-learning experts in biology have set their sights on new frontiers, now that convolutional neural networks are taking flight for image processing. “Imaging is important, but so is chemistry and molecular (分子) data,” says Alex Wolf, a computational biologist. Wolf hopes to improve neural networks so that they can analyse gene expression. “I think there will be a very big breakthrough in the next few years,” he says.

Shrieking Toad and Dancing Ant
Kids got nicknames at a summer camp, and mine is Shrieking Toad (尖叫的蛤蟆). I guess it was my fault that I couldn't get a cool one.
A bunch of us campers were on our first nature walk. When we broke for lunch, we sat down on logs. I was on my nuts when a tree frog dropped onto my shirt from the branches above. I shrieked. It was totally unconscious and I didn't even know I could make a sound like that. Most kids forgot about it except Stan. Whenever I walked by, he'd shout, “Shrieking Toad, show us how you can hop!” I corrected him that it had been an eastern gray tree frog, not a toad, but that just made things worse.
Three days later, Counselor Matt announced we would be paired for a treasure hunt. Excited whispers spread through the camp. But when he read “Jay and Stan” as a team, my nerves got completely fried. Stan shouted, “Great! Shrieking Toad!” Then he called to the group, and I went red at what came out of his mouth. “Guys, if mosquitoes are bugging you, ask Shrieking Toad to eat them. Toads love bugs!” Kids roared with laughter.
After all the teams wandered off, Stan and I were alone. Then I had a great idea, surprising myself that I hadn't thought of it earlier. I suggested we split up so as to have a better chance of finding treasures. “Yeah, I'd better do what I'm toad (told).” Stan laughed and set off.
Ten minutes later, I heard something that reminded me of myself a few days ago. I ran toward the sound. I never would have believed it if I hadn't seen it with my own eyes. Stan was jumping around near a mud pool like a monkey, shrieking and yelling something that sounded like “Dance! Dance!” Seeing him scratching at his body and hitting at his clothes made me realize what he was really saying: “Ants! Ants!”

10 . The capital of a country is often a very populated city where much history has been made due to the high-level political and economic functions that occur there. However, sometimes government leaders decide to move the capital from one city to another. Capital relocation has been done hundreds of times throughout history. The ancient Egyptians, Romans, and Chinese changed their capital frequently.
Some countries choose new capitals that are more easily defended in a time of invasion (侵略) or war. Some new capitals are planned and built in previously undeveloped areas to promote development. Countries sometimes change their capital because they expect some type of political, social, or economic benefit. They hope and expect that the new capitals will surely develop into cultural treasure and hopefully make the country a more stable place.
Here are capital relocations that have occurred in approximately the last few centuries.
