1 . The green, natural forest absorbs carbon dioxide from the air through photo- synthesis (光合作用). There is another way of dealing with the climate crisis. That is setting up fields of dark-colored solar panels (太阳能电池板), also known as “solar forests”, which replace power stations that use fossil fuels such as coal and gas to make electricity, thus mitigating harmful emissions (排放) of greenhouse gases.
But since they are both relatively dark, they absorb a lot of solar radiation. Some of the energy is used for photosynthesis in natural forests or to produce electricity in “solar forests”, but most returns to the atmosphere, heating it up. Then what would be the more effective land use option in terms of the climate crisis: planting a forest, or building solar panels? This issue has long been debated by decision-makers around the world. Now, we may have an answer, thanks to a new study.
First, the researchers compared the impact of a forest on the climate crisis in a dry area to that of a solar farm in a similar environment. The researchers found that the albedo effect (反射效应) of both of these “forests” was similar, but that the absorption or prevention of carbon emissions was very different. It turns out that it takes 2.5 years for the heat emitted by solar farms to be balanced by the carbon emissions that are avoided, thanks to the energy they produce. In the case of a natural forest of similar size, it would take more than 100 years of photosynthesis to balance its heating effect.
The researchers also studied how the heating-cooling relationship changed in other climates and found that in more humid environments, the heating effect of planting large numbers of trees is smaller. And the break-even point is reached within 15 to 18 years.
“In dry places, building solar forests seems far more effective in addressing the climate crisis. Meanwhile, forests absorb about a third of annual carbon emissions and play a vital role in the global rain cycle, in maintaining biodiversity and in many other environmental and social contexts. Preventing them from being cut down and planting more trees in humid areas are of great significance,” explains one of the researchers in the study.

2 . As I was standing in a long line to get into the grocery store waiting to buy fruits and vegetables, I realized I could turn my backyard into a garden.
Before you start your work, think about the space you’re changing. Is your space a yard? A rooftop? How much sunlight does it get? Watch out for the temperature and find out which plants adapt well in your region.
Set the stage with healthy soil. It’s full of billions of bacteria and helps plant roots grow. Then consider the structure of the soil. Different plants require different soil.
Should I plant seeds or transplants? In general, a seed is like a baby. It needs tons of care, but not everyone knows how to get it to survive. Transplants are for starters.
With a little planning, I was able to watch three adorable baby trees take root in my yard. One of them recently had its first fruit — sweet little peaches. The yard has totally transformed too.
| A．It used to be a junkyard. |
| B．Just create a vision based on your location. |
| C．You can start a garden in pots or containers. |
| D．You can buy your garden soil at a hardware (五金) store. |
| E．It enables me to grow my own food and save waiting time. |
| F．Carrots want sandier soil, so their roots can more easily grow. |
| G．They are plants that are a few inches high grown in small pots. |
When I was a kid, my parents and I lived near the forest. They often told me that our family was a team that needed to work together for the household to function smoothly. There was always an abundance of work to do — cooking, cleaning, and walking dogs. I volunteered to walk our dog, Max, who had been adopted one month before. I never dared let this giant dog off the lead (牵狗绳), just in case he took off.
One morning, we were walking along in the forest when Max started pulling on the lead. At first, I was able to hold on despite the wet ground from a recent shower. But the more I tried to stop him pulling, the more it turned into a tug of war. And thanks to the slippery ground, I lost.
Pulling his lead, Max shot off like a bullet, leaving me screaming behind. I chased him but lost my footing and fell face-first into some mud. I stumbled (踉跄) to my feet, but looking ahead, I found him running back towards me. I thought he was going to stop and give me his “Sorry” look. But instead, the dog shot past me and returned after a while.
As soon as we got home, my mother immediately attended to Max with a warm towel and a doggy treat. I thought seeing me stumbling and covered in mud, I would also get a warm cup of tea and a motherly kiss. Instead, I got a very loud lecture about letting the dog loose in the forest.
I felt frustrated. It wasn’t fair that she didn’t understand how difficult it was to control Max. I fought back, “Stop lecturing me! Why is everything my fault?” With these words, I stormed into my bedroom and slammed the door shut.
In the evening, I heard my mother call Max and take him out. It wasn’t long before I heard my mother screaming and the door opening again.

___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________My parents were always against me owning my own pet, afraid of the mess it would make or that I would quickly lose interest in taking care of it, but we made a compromise: I could volunteer at a local pet shelter on the weekends to test my sense of responsibility and dedication. That was how I first came to volunteer at the Avondale pet shelter and—more importantly—where I met my future best friend, Chocolate.
One hot August afternoon, my boss Charlie told me that they were bringing in a young black Labrador Retriever and that I’d be its primary caretaker. An hour after our conversation and in came Chocolate—a beautiful dog with shining brown fur and amazing blue eyes. At about 3 months old, I expected him to be a lot more energetic and playful, but he immediately backed and lay down at the back of his pen (围栏).
I asked Charlie what was the matter with him. He replied that Chocolate had a genetic problem which caused him to be born with a short tail, leading potential owners to think there was something wrong with him; so the breeder felt that they had no choice but to give up the puppy to the shelter.
He was overlooked and underappreciated. I felt very angry at the thought that an otherwise healthy dog could be thrown away so easily. At the same time, I felt a deep sympathy for this dog who had been cheated out of the love and attention he deserved. It was at this moment that I resolved to give Chocolate as much love and attention as I could while working as a volunteer.
Although Chocolate was reluctant and shy at first. eventually through enough treats and play he slowly came around and warmed up to me. Soon enough, whenever I came around his pen to let him out for his turn of walks and play, Chocolate was always excited and jumping with joy.

Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.
Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).
Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.
Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.
The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.

6 . In the Seychelles archipelago (塞舌尔群岛) in East Africa, flooding and erosion (侵蚀) caused by rising sea level pose an incoming threat to the country’s many low-lying islands. At the same time its mangrove forests (红树林), which serve as a vital aspect against these impacts, are disappearing: Approximately 70% of Seychelles mangroves have been destroyed since the late 1700s due to human-driven development and agriculture as well as soil erosion from sea-level rise.
Today the Seychelles Government is working with local community leaders to restore the mangroves, and not just for protection against rising sealevel. Research shows that these forests can store about 2.5 million tonnes of CO2 (equal to taking 500,000 cars off the road for a year), directly helping to fight climate change. They also provide a breeding ground for fisheries, a sector that contributes one-fifth of the country’s GDP, benefiting local communities’ livelihood and helping to protect the islands’ lively biodiversity (多样性).
While the concept of using nature to benefit both lives and lands is by no means new, global interest in “nature-based solutions” has skyrocketed in recent years. Many now see nature-based solutions as a key approach for addressing not only climate change but a range of social, environmental and economic challenges — from biodiversity loss, food security and air pollution to disease control and declining local economies.
Yet there remains widespread debate about what exactly constitutes a nature-based solution as well as how to best include these strategies into broader climate and conservation efforts. This indetermination has contributed to significant under-investment: It’s estimated that to limit temperature rise to below 1.5 degrees C (degrees F), hold back biodiversity loss and control land degradation (恶化), annual investments in nature-based approaches must be three times by 2030.
As nature-based solutions continue to rise on the global agenda, building a more consistent understanding around the concept and its implications will be key to raising support for effective, extensive solutions that benefit both people and the planet.

9 . Both ants and human beings respond to isolation in similar ways. In isolated individuals of both species, researchers have observed that the immune system is less efficient.
Humans and other social mammals will experience high levels of stress when they are isolated from the group, which has a negative effect on both well-being and physical health. Isolated people tend to become anxious, depressed, lonely, and more subject to addictions. They will also have a weaker immune system, and the isolation will impact their health negatively overall. While these effects have been well studied in humans and mice, relatively little is known about how isolation affects social insects.
Ants are extremely social. They will live their entire lives as part of the same colony (群体) and their survival will be entirely dependent on their nest mates. This social function is so important to them that worker ants will abandon their reproductive capacity and devote themselves to tending to the needs of the queen and the colony.
Researchers paid attention to ants of the Temnothorax nylanderi, which is a European species that will create colonies inside acorns (橡实) and sticks. These colonies consist of a few dozen workers, and the researchers took individual members and isolated them for various periods of time, from an hour to 28 days. The study revealed three key aspects of the effects of isolation.
When the isolated workers were returned to the colony, they showed less interest in other adult ants, and instead chose to spend more time with the brood (幼雏). They were also less interested in cleaning themselves, which is a behavior noticed in most social animals that are isolated. This behavior increased the risk of parasite (寄生虫) infections. The third observation was related to the gene activity of the isolated individuals — genes that were responsible for stress response and immune system function were less active. Once again, this is something observed across all social animals. What this research tells us is that social behavior is something extremely ancient and it could be traced back to a very old common ancestor between animal and insect species.

10 . A new study suggests that pollution of all kinds kills nearly 9 million people worldwide each year. Air pollution from industrial processes and the expansion of cities accounted for about 75% of the deaths, researchers found. The study was based on examinations of worldwide death rates and pollution levels.
The study separated traditional pollutants from modern pollutants. Examples of traditional pollutants are indoor smoke or wastewater. Modern pollutants include air pollution from vehicles or industrial activities and poisonous chemicals. The researchers found that deaths from traditional pollutants are dropping worldwide. But they remain a major problem in Africa and some other developing countries. In some countries, state programs to cut indoor air pollution and improvements in sanitation (卫生) have helped reduce death rates. In Ethiopia and Nigeria, for example, such efforts cut deaths by two-thirds between 2000 and 2019, the study found.
Modern kinds of pollution are rising in most countries, especially developing ones, the researchers said. Deaths caused by modern pollutants — heavy metals, agricultural chemicals and carbon emissions—are “skyrocketing,” said study co-writer Rachael Kupka. She heads the New York-based Global Alliance on Health and Pollution. Kupka said deaths linked to modern pollutants had risen 66% since 2000.
“Nine million deaths is a lot of deaths,” Philip Landrigan told The Associated Press about the study’s results. He is director of the Global Public Health Program at Boston College in Massachusetts. “The bad news is that it’s not decreasing,” Landrigan added. “We’re making gains in the easy stuff, and we’re seeing the more difficult stuff, outdoor industrial air pollution and chemical pollution, still going up.”
The study makes several suggestions for ways to cut the number of deaths. These include creating better recording and reporting methods and stronger government policies to reduce pollution linked to industrial activities and vehicle emissions.
“We absolutely know how to solve pollution problems,” said the study co-author Richard Fuller. “What’s missing is political will.”
