1 . Sometimes it seems hard to try to make an impact on this world of ours. Often, students and their communities can begin by focusing on environmental changes. By making pretty simple changes schools can impact the earth in a positive way.
Use Less Paper
Start a Recycling Club
Encourage students who are enthusiastic about environmental causes to take the lead in your school by starting a recycling club. This group can be in charge of making sure each classroom has a recycling bin and helping collect the recyclables on a weekly basis.
Make Eco-Friendly Purchases (购买)
Schools can encourage students to make purchases unharmful to the earth.
Students are looking for a way to be a positive force in this world.
| A．Schools can easily save trees by finding ways to use less paper. |
| B．Districts can also offer students access to online textbooks and workbooks. |
| C．Here are a few ways to inspire your school to help protect our environment. |
| D．This group can also help sort cafeteria packaging so more of it can be recycled. |
| E．With minor changes as mentioned above, schools can help students achieve that. |
| F．Removing as many plastic school supplies as possible can have a massive impact. |
| G．Then students and teachers can expand this greenery by working together to build a garden. |
2 . For millions of years, sea turtles (海龟) have been making the great journey from Costa Rican beaches to the ocean.
Female sea turtles come to shore to nest (筑巢) on the same beach where they were born. Scientists are not sure how sea turtles remember where they were born, but they believe that sea turtles can use the Earth’s magnetic field (磁场) to help them find their way back. Mother sea turtles usually nest every two to three years, but they might lay two or three nests in one year.
Unlike most animals, the temperature inside the nest determines whether the turtles will be male or female. Warmer nests produce more female turtles. It can take from six weeks to two months for baby turtles to appear from the nest. Once they sense cooler nighttime temperatures, they will begin their perilous journey towards the sea. The little turtles’ journey to the ocean isn’t a leisurely walk on the beach. In fact,on some beaches, only 10 percent of them make it to the ocean.
Natural hunters are not the only threat to sea turtles. Humans and their activities have also severely reduced the number of sea turtles in the oceans. Fishing activities, boat traffic, artificial (人工的) lighting, and pollution are making the trip from beach to ocean difficult. Due to a variety of these threats, six out of seven sea turtle species worldwide are considered endangered or threatened.
While sea turtles may face several threats to their survival, there are many opportunities for humans to help them. For example, avoid fishing in waters that are known to have sea turtles. If you do accidentally hook (钓) a turtle, do not remove the hook. Instead, call local wildlife authorities to help with removal. Lights draw baby turtles away from the ocean. Turn off your lights at night when you are near a sea turtle nesting area. Another way to help sea turtles is to reduce your plastic use. Plastic litter is among the number one causes of deaths of sea turtles. Last, get involved with sea turtle protection efforts.

3 . After taking a few steps back, Hadj Benhalima rushed toward the building, pushed himself upward with his foot against the wall and stretched out his arm. At the peak of his jump, he flipped off a light switch, and the bright lights of a nearby barbershop went off immediately.
This is what Hadj and his friends have been doing for the past two years: swinging around Paris and switching off wasteful shop signs at night, in an effort to fight against light pollution and save energy. And they are all enthusiastic about Parkour — a sport that consists of running and jumping over urban obstacles.
While climbing other people’s property to turn off their lights may strike some as a form of trespassing (非法入侵), the Parkour athletes insist their activities are only about enforcing seldom-respected rules.
More than a decade ago, Paris City Hall issued orders requiring stores to turn off all signs and window displays from 1 am to 6 am, but they are widely ignored with little consequence. “for 10 years there has been no follow-up, no control, no punishment,” said Anne-Marie Ducroux, the head of the National Association for the Protection of the Sky and the Night Environment.
That is why Hadj and his friends have taken matters into their own hands. The group often gathers in the so-called Golden Triangle neighborhood, in western Paris, which is the center of French luxury.
Enforcing the orders in place of the authorities certainly enters a legal grey area. But the Parkour athletes say all the police officers they have met during their rounds have allowed their action — as long as it causes no damage.
And it seems that their efforts have produced the desired result, because Hadj says he has noticed that in recent months, several shops have stopped leaving their lights on after his group targeted them. He hopes others will follow suit. “At least, I’ll sleep better,” he said.

Meagan and her close friend Samantha, both school teachers, lived together in an apartment in Denver. On mornings when Samantha had class, Meagan would help to watch her 2-year-old daughter, Hannah. Also part of the household was Meagan’s pet, Willie, a particularly intelligent and chatty parrot.
Willie was indeed funny and a good talker. In addition to some vocabulary learned from Meagan, he became a great mimic (会模仿的动物) of cats, dogs, and chickens. Plus, he could sing along to the radio. The bird was a nice playmate for the little girl, and he always knew how to lift her spirits. The bird was more than just a pet; he was a member of the family.
One day, with Samantha at school, Hannah had comfortably positioned herself in front of morning cartoons while Meagan was busy cooking in the kitchen, preparing the little girl her favorite breakfast treat, an apple pie. When Meagan was done baking the apple pie, she placed it at the center of the kitchen table to cool. She looked at Hannah and, confident the child was fully engaged with the TV, walked out of the kitchen quickly to use the bathroom.
Meagan was gone maybe 30 seconds. And suddenly, she heard the bird going crazy, screaming loudly. She heard two very distinct words from the parrot’s mouth. “Mama! Baby!” Repeated over and over again. “Mama! Baby! Mama! Baby!”
Meagan ran out of the bathroom to find Hannah in the kitchen, holding the partly eaten apple pie, fighting for breath, her face and lips a terrifying shade of blue. And Willie was still screaming loudly.Hannah had climbed up on a chair, gotten the apple pie from the kitchen table and was clearly choking on it.
注意: 1.续写词数应为150左右；2.请按如下格式在相应位置作答。
With a pounding heart, Meagan grabbed Hannah immediately.

Flash droughts develop fast, and when they hit at the wrong time, they can ruin a region’s agriculture. They’re also becoming increasingly common as the planet warms. In a study published in the journal Communications Earth& Environment, we found that the risk of flash droughts, which can develop in just a few weeks, is on the rise in every major agricultural region around the world in the coming decades.
In North America and Europe, cropland that had a 32% annual chance of a flash drought a few years ago could have a greater chance of a flash drought by the final decades of this century. That result would put food production, energy, and water supplies under increasing pressure. The cost of change will also rise. A flash drought in the Dakotas and Montana 2017 caused $2.6 billion in agricultural damage in America alone.
All droughts begin when rainfall stops. What’s interesting about flash droughts is how fast they strengthen themselves, with some help from the warming climate. When the weather is hot and dry, soil loses moisture rapidly. Dry air extracts moisture from the land, and rising temperatures can increase this evaporative (蒸发的) demand. The lack of rain during a flash drought can further contribute to the feedback processes. Under these conditions, crops and vegetation begin to die much more quickly than they do during typical long-term droughts.
In our study, we used climate models and data from the past 170 years to assess the drought risks ahead under three conditions for how quickly the world takes action to slow the pace of global warming. If greenhouse gas emissions from vehicles, power plants, and other human sources continue at a high rate, we found that cropland in much of North America and Europe would have a 53% annual chance of flash droughts, by the final decades of this century. Globally, the largest increases in flash droughts would be in Europe and the Amazon. Slowing emissions can reduce the risk significantly, but we found flash droughts would still increase by about 6% worldwide under low emission conditions.

6 . In 2014, an art student from university went to Beijing Zoo. Little did he know that a chance encounter with corals (珊瑚) there would start a lifelong passion. Until today, Xu Yitang, a Beijing native, has settled in Hainan province, where he serves as a coral conservationist. For Xu, who had been studying Peking Opera since childhood, becoming a coral conservationist was an unexpected turn of events.
After he first saw corals at the zoo, he began to frequent the local market to learn about coral farming from sellers of coral products. He also learned diving and underwater photography to get a closer look at corals for research purposes. Each day, he spends several hours diving deep under the waves to observe and document the growth and development of the creatures and shares photos and videos of corals on social media platforms. His goal was to raise awareness and knowledge about corals, so that people can learn how to protect them effectively.
As he studied deeper into the creature, he learned that corals are known as “underwater gardens” of the ocean, providing a home for a quarter of all ocean life. Unfortunately, with the strengthening of the greenhouse effect, rising sea temperatures have led to coral bleaching (白化). Xu felt an increasing sense of urgency and responsibility to protect them.
While pursuing his passion to protect corals, he met his life partner, Liu Xiwen, through their shared hobby of diving in Hainan. “Unlike many young people who care about their dress and appearance, he is simply focused on protecting corals,” says Liu about Xu.“Despite his skin injury from spending long hours in the seawater, his attitude is different from what I’ve seen in most young people in Beijing, and it’s attractive to me.”

9 . Slobodchikoff, a biologist who has spent years working to better understand the calls of dogs, used that knowledge to help people who were having trouble with their pets.
A man reported his dog wanted to bite him. So Slobodchikoff went to the man’s house. He watched as the owner walked over to the dog, towered over the pet and then said, “Good dog!” in a low-pitched(音高) voice. “The dog ran into a corner,” Slobodchikoff recalled. The owner had scared the dog. Slobodchikoff recommended that the man should do the opposite. The owner took that advice—and ended up developing a great relationship with his pet.
Not everyone has the time to study dog communications or the money to bring in an expert. Slobodchikoff thinks tech could help. He thinks a cell phone app or device that you could point at a dog. This would record video and audio(音频) of a dog’s behavior and then upload it.An artificial intelligence(AI)system would later analyze it.
The AI “ would translate this for you into English or any other language,” says Slobodchikoff. The result, he explains, may be something like “‘I’m hungry’ or ‘I need to go outside to pee’ or ‘I want to go for a walk.’”
To train the AI system, Slobodchikoff planned to get data directly from pet dogs, but for some reason, he hasn’t yet restarted the project to date, but hopes to soon.
Search an app store for a pet translator and you’ll find plenty. Some are completely unscientific and silly. MeowTalk, however, is a cat-translation app based on an AI model. In 2021, its creators reported that the AI model achieved 90 percent accuracy at identifying nine different emotional states in meows. These included angry, happy, hunting, pain and rest. The app picks conversational phrases based on these emotions, like “nice to see you,” or “let me rest.”
People who have tried the app say it doesn’t always work well. But better translations of barks and meows may be just around the corner.
