3 . People flood into cities for understandable reasons: more job opportunities, more cultural diversity and larger communities. Yet living in a concrete-walled, green-poor, urban environment takes away from our-very essence our fundamental need to be close to nature. We can’t quite break the link with our evolutionary (进化的) past and part ways with our origins. Surrounding ourselves with walls and ‘screens, we tend to pay a price, often with our health and quality of life.
In Japan, a populous country with vast expanses of green forests, an ancient tradition, known as shinrin-yoku, or forest bathing, tries to balance out the pressure from urban living. It’s the practice of spending prolonged periods of time with trees to gain from their many health benefits. In a book hitting shelves this month, Forest Bathing: How Trees Can Help You Find Health and Happiness, Dr. Qing Li, the world’s foremost expert in forest medicine, introduces readers to the valuable practice of forest bathing. The book features more than 100 color photographs of forests around the world. One may reject this kind of book as yet less convincing, but the point is that Li has not just practiced forest bathing, but has also studied its impact on people’s health through numerous scientific studies. He has data to support his claims, collected in a long list of expert-reviewed articles at the end of the book.
The book lists studies that consistently show-a substantial, reduction of stress hormones (应激激素). Essential tree oils found in forest air increase energy levels by more than 30 percent and improve a general state of well-being, including improvement in sleep.
Scientific results apart, the, concept of forest bathing shouldn’t be so surprising. Who hasn’t felt an inner sense of well-being when walking along a quiet forest path? Stepping into a forest, away from the artificial sounds and smells of urban life, does feel like pushing a life reset button, reestablishing a connection with our deepest needs.
To celebrate this wonderful book and. what seems to be a rediscovery of forest bathing in our life, I’m going to go now—to take: my forest bath.

4 . Dozens of dolphins swam out of the polluted waters of Haifa Harbor on Tuesday. This was the first time that dolphins had visited this crowded Mediterranean Port, and researchers were surprised by the unexpected event.
Between 40 and 50 of the dolphins appeared in the busy port on Tuesday morning, obviously drawn by the fish-rich waters of Haifa Bay.
However, the bay is also full of harmful chemicals. Avia d Sheinin, professor of Haifa University’s Maritime Studies Department, said he didn’t think the dolphins were harmed by the pollution, but that he hoped they would swim back to the sea soon. “It seems that they are quite relaxed. They don’t seem to be stressed,” he said.
Haifa Bay is lined by chemical companies that have been pouring poisonous waste into the water for decades. While pollution levels have dropped in recent years, the water is still considered a health hazard, whispering warnings to those who draw near.
“There are lots of fishes in Haifa Port. Unfortunately, we couldn’t tell the dolphins that the fish are not healthy, and I don’t know what the result will be,” he told Israel Army Radio.
Hundreds of Haifa residents gathered around Haifa Bay to see the interesting sight, and researchers said this provided a rare chance to film and study the rough-toothed dolphins. In addition to the dozens of dolphins which swam into the port on Tuesday, a similar number stayed outside the breakwater (防波堤). Later Tuesday the dolphins left the port but remained near the entrance and Israel’s coastguard was patrolling (巡逻) the area to try to make sure the dolphins didn’t re-enter the poisonous waters.
Relatively little is known about rough-toothed dolphins, which are usually found in deep and warm tropical waters.

I can count a dozen friends, all in the 1950s, who adopted a puppy. Actually, I did, too. Last year, I was suddenly consumed by the urgent desire to acquire a seven-week-old Australian shepherd. For one thing, this breed is one of the most energetic on the planet, whereas I am bookish, lazy, and middle-aged.
My trouble with dogs is that I never have the remotest clue what they want, and they never seem to have the slightest idea of what I’m saying to them. He was highly alert, yet unable to grasp a single thing. Kevin’s entire communicative gestures — whether he wanted food, exercise, permission to jump on the sofa, a toy, or, who knows, a conversation about the electric bill — consisted of walking up to me and staring. He did this about 50 times a day, just staring brightly without moving a muscle, and after years of living together, I still didn’t know what he wanted. We coexisted in a state of profound mutual (相互的) incomprehension.
“Sometimes I think,” I wrote in my journal, “it doesn’t matter that I don’t know what he wants, because we have nothing in common. Whatever he wants will be something I don’t want. He probably wants me to go outside and chase squirrels. I don’t want to.”
But one afternoon, there was only Kevin and I at home. My husband was on business abroad for several days and my son was also abroad attending college. I enjoyed my favorite book leisurely while Kevin had a rest or stared at me as usual. It suddenly began to thunder aloud and soon rained cats and dogs. I dashed out of the front-door to fetch the vegetables in my parking lot. The wind was so strong that the front-door just slammed loudly, closed, after I made my way out. Worse still, when I came back with the rescued vegetables, I found the keys were not with me. There was also no backup (备份) of the keys outside my house.

6 . Flora was playing with her new dog Stitch, while wearing a favourite second-hand sweater. Stitch jumped up and grabbed her sleeve-and tore several holes in it with her sharp teeth.
Flora wasn’t about to throw the item out. “I can’t bring myself to throw away nice clothing just because of a hole, ”she explains. She decided to tackle a new skill repairing. She began by reading a book called Make Do and Repair, about the innovative ways to avoid waste.
Instead of tying to make the repair as small as possible, she turned to “visible fixing, ”a fashion in repairing clothes that leaves an intentionally obvious fix. She added flowers, or other small designs to damaged clothes. “Every time you do a repair, it’s like getting a new piece of clothing, ”says Flora.
Sadly, we have been in the habit of replacing things instead of repairing them—and the garbage is piling up. Worldwide, we throw out 92 million tonnes of fabric every year.
The good news is that fixing things can help solve the waste problem. It’s part of a larger shift toward a circular economy -the idea that instead of throwing out items once they are broken or out of date, we reuse or repair them, keeping them out of the waste yard for as long as possible.
There was a time when people fixed things themselves or called their local repair shop, But as more items were produced and prices dropped, replacing even a big appliance became more convenient.
That’s changing, in part due to information now available online. The popular how-to site iFixit. com has enabled more than 100 million repairs.
“Companies have been designing products that break easily or become outdated quickly, forcing consumers to buy new ones or purchase upgrades. We’re now seeing some producers show interest in making it possible for users to repair things. Some companies are selling official parts and sharing their repair guides through iFixit. IFixit has grown into a database with over 100, 000 repair manuals. We have this vision of a world where repair is the expectation for all things that are made, ”says Chamberlain, director of iFixit.
1. Why did Flora read a book?| A．For innovation. | B．For repairing skills. |
| C．For a better life. | D．For dog-raising information. |
| A．People’s habit. | B．Repairing quality. |

7 . To protect people living in areas that are likely to suffer flooding and rising sea levels, a group of architects has designed a floating home.
The project is a collaboration between British architect firm Grimshaw and Dutch manufacturer Concrete Valley. Currently at the design stage, the home will be constructed using a concrete and glass framework, which sits on a floating pontoon structure. In the event of a tidal surge or flooding, the pontoon rises with the water level to keep the home safe. Fitted with solar panels and heat exchangers, the water home will be able to produce their own electricity during power cuts, in the event of a storm.
Other firms are exploring floating homes, too. In the UK, Baca Architects has partnered with manufacturer Floating Homes. Their design was originally an entry to a competition to reduce London’s housing shortage, and has since been turned into a prototype. Baca Architects is exploring ways to provide practical, affordable, flood-resistant additional city housing, which could occupy unnecessary docks, canals and other waterways throughout London, director Richard Coutts told the Guardian.
As the planet’s atmosphere warms, areas such as the Arctic are melting fast, contributing to rising sea levels and higher risk of flooding. The ocean is already reclaiming land in some parts of the world. With the global population set to reach 9.8 billion people by mid-century, extreme flooding could further add pressure to limited land, water, food and other resources. These challenges are at the heart of the Virtual Ocean Dialogues, an initiative by the World Economic Forum and Friends of Ocean Action. The online event provides a forum for more than 50 world leaders to address the most pressing challenges facing our oceans and develop ways to protect them.
While floating homes may be a common feature in parts of Asia and other developing regions, they are emerging as a way to relieve overcrowding and protect people in busy cities and urban areas which are likely to suffer from flooding.

9 . A recent report revealed that, in the US alone, 27 million tons of plastic ended up in landfills in 2018, but only 3. 1 million tons were recycled. Worldwide the numbers are similarly bad, with just 9% of plastic being recycled. The statistics are even worse for certain types of plastic. For example, out of 80,000 tons of polystyrene(聚苯乙烯) containers generated in the United States, only a small amount (less than 5,000 tons) was recycled.
Now, researchers at The University of Queensland have found a species of worm with an appetite for polystyrene could be the key to plastic recycling on a mass scale. The superworm can eat through polystyrene, thanks to a bacterial enzyme(酶) in their gut. To study how superworms react to purely plastic food, researchers broke up 135 of the creatures into three teams: one was fed only wheat bran(麸皮), another was fed only plastics, and the third was given nothing.
“We found the bran-fed worms have been significantly healthier than the plastic-fed or starved worms, more than doubling their weight over the three weeks they have been monitored. Though the plastic-fed worms made less impressive gains, they still put on more weight than the starved worms,” Dr. Rinke said.“This suggests the worms can get energy from plastics, most likely with the help of their gut microbes.”
Researchers used a technique called metagenomics to find several encoded enzymes with the ability to degrade(降低) polystyrene. The long-term goal is to engineer enzymes to degrade plastic waste in recycling plants.
“Superworms are like mini recycling plants, eating the polystyrene and then feeding it to the bacteria in their gut,”Dr. Rink e said. It’s hoped this bio-upcycling will promote plastic waste recycling and reduce landfills. Researchers said they aim to grow the gut bacteria in the lab and further test its ability to degrade polystyrene. Then they can look into how to upscale this process to a level required for an entire recycling plant.

10 . Cats and many other animals, including most dogs, can reflect light from their eyes. That’s why cats’ eyes will usually shine brightly in photos taken in a dimly lit room or glow when lightened in the dark by a flashlight or a car’s headlights.
Species whose eyes glow have evolved to see better in low light because they either forage or need to look out for predators (天敌) throughout the night, or they do most of their hunting at dawn and dusk. In fact, domesticated cats can see in conditions that are only 16% as bright as what people require.
Cats accomplish this because their pupils (瞳孔) — the openings that appear black in the middle of their eyes that widen and narrow in response to light conditions—are special. Pupils operate like windows, with bigger ones letting more light into the eye. And a cat’s pupils can become up to 50% larger than human pupils in dim light. They also have a higher number of a specific type of light-sensing cell in the back of their eyes than we do. These cells, called rods (杆细胞), catch low-level light. In addition to having large pupils and lots of rods, cats have something people don’t: a tapetum lucidum (荧光膜), a Latin medical term that translates to “bright or shining tapestry”. The tapetum lucidum is also known as “eyeshine”.
It’s located in the back of the eye behind the retina (视网膜) — a thin layer of tissue that receives light, converts the light to an electrical signal and sends this signal to the brain to interpret the image．
A cat’s tapetum lucidum is made up of cells with crystals that, like a mirror, reflect light back to the retina. This gives the retina a second chance to absorb more light.
In cats, the tapetum most often glows yellow-green or yellow-orange, but the color varies, just like their irises (虹膜) — the colorful part of their eye, which can be green, yellow, blue or golden. Variation in tapetum color is not unique to cats and can be found in lots of species.
