1 . The rechargeable lithium-ion (锂离子) battery market is worth more than ＄50 billion. Lithium-ion batteries, whose demand continues to go up day by day, are used in a wide range of electronic devices. They are made of four main components, and cathode (阴极) is one of them. The cathode’s active material type is what determines the capacity of a battery.
A recent study, led by Wang Yan, a material scientist of Worcester Polytechnic Institute, finds that lithium-ion batteries made with recycled cathodes work better than those with new cathodes.
“The battery industry is expected to grow sharply in the next decade. This high demand has led companies to go to extremes, like increasing deep-sea mining, to gain access to the minerals used in lithium-ion batteries,” Wang said. “Mining minerals will have environmental impacts. Recycling spent lithium-ion batteries offers a way out.”
But until now, the prospect of using recycled materials in lithium-ion batteries has some manufacturers (制造商) worrying that it could impact performance. Thus, lithium-ion batteries are still not widely recycled. Aware of decreasing resources and environmental impact, Wang and other researchers set out to find a way to make recycling lithium-ion batteries economically practical. Through experiments, they could recover more than 90% of the key metals from spent batteries. These recovered metals became the basis of the new recycled battery’s cathode’s active material.
In tests between Wang’s team’s recycled batteries and brand-new batteries of the same composition, the recycled batteries outperform the new ones in their ability to maintain capacity. It took 11,600 charge cycles for recycled cathode batteries to lose 30 percent of their original capacity. That was about 50 percent better than the 7,600 observed cycles for new cathode batteries, the team reported. Those thousands of extra cycles could translate into years of better battery performance, even after repeated use and recharging.

2 . Michael Gonsalves, a chef of Golden Oak at Disney World, has a cuisine concept rooted in fresh, locally-sourced ingredients that originated from childhood harvesting produce from their family garden with his mom to eventually leading kitchens at Walt Disney World Resorts to employ a sustainable model.
“Truly the whole process starts with menu planning,” he said. Creating one dish leads into the creation of many more through the end-to-end use of products. As chefs, they are always searching for the best ingredients. It is then their focus to ensure they appreciate and respect all that go into each and every one of them. For example, they source chicken that is naturally grown and fed on a natural plant forward diet, no hormones (激素) or additives — that’s used in many ways throughout menus from a simple grilled chicken breast to bone soup. Nothing goes to waste.
When they do have waste, even if minimal, they shift it from landfills to transform it into compost (堆肥) that’s then used across the Walt Disney World property. They also support Second Harvest, a local community food bank where healthy produce, prepared, but not served, meals eatable for human consumption are donated. Disney also works with pig farmers when they can’t distribute foods past the point of safety for human consumption. Besides, wildlife reservations love to get the meat because tigers and wild cats can still eat that.
Their operations are “on a path to a sustainable zero waste kitchen of tomorrow” where chefs learn the full-life cycle of plants from seed to plate and gain a better understanding and appreciation for the product and their craft.
Golden Oak at Disney has millions of bees that produce up to 300 pounds of honey per year, plus those bees help with cross pollination (授粉) of their gardens on a daily basis. They advocate a culture that helps develop not only the quality of food, but an appreciation for nature.

3 . The science of why insects gather around lights at night has never been nailed down. Popular theories propose that moths and other insects navigate (导航) by the moon and mistake lamps for moonlight, or that the insects fly towards light to escape coming danger. Now researchers believe they have a more convincing answer: contrary to current theories, insects are not attracted to light from far away, but become trapped if they fly close to an artificial light source.
According to Dr Sam Fabian, study co-author and Imperial College London entomologist, moths and many other insects that fly at night evolved to tilt (倾斜) their backs to wherever is brightest. For hundreds of millions of years, this was the sky rather than the ground. The trick told insects which way was up and ensured they flew level. But then came artificial lighting. Moths found themselves tilting their backs to street lamps. This caused them to circle around the lamps endlessly, the insects trapped by their evolution.
Fabian and his colleagues filmed insect flight paths around lights in the lab. The videos reveal that time and again, moths and dragonflies turned their backs to artificial lights, which appeared to greatly change their flight paths. If the light is above them, they might start orbiting it, but if it’s behind them, they start tilting backwards and end up flying in circles or diving toward the ground.
Researchers have long warned that light pollution is a big driving force in the dramatic decline in insect populations. Moths and other insects that become trapped around lamps become easily caught by bats. The artificial lighting can also fool them into thinking it is daytime, causing them to bed down and skip a night’s feeding.
There are, Fabian believes, helpful lessons from the research. “What this tells us is that the direction of artificial light matters. Could we change lighting environments to not trap insects? For we’re facing a massive decline in insects around the world, and artificial light at night is one of the factors that could potentially be leading to this decline,” Fabian said.

4 . For the first time, United Nations members have agreed on a unified treaty (协议) to protect biodiversity on the high seas, representing a turning point for vast stretches of the planet where conservation has previously been held back by a confusing patchwork (拼凑)of laws.
The UN Convention on the Law of the Sea came into force in 1994, before marine biodiversity was a well-established concept. An updated framework to protect marine life in the regions outside national boundary waters, known as the high seas, had been in discussions for more than 20 years, but previous efforts to reach an agreement had repeatedly failed. The unified treaty, which applies to nearly half the planet’s surface, was reached late on Saturday.
UN Secretary-General Antonio Guterres welcomes the finalization of the text of the United Nations Ocean Treaty, his spokesman said on Saturday. “This breakthrough, which covers nearly two-thirds of the ocean, marks the culmination of nearly two decades of work and builds on the legacy (遗产)of the United Nations Convention on the Law of the Sea,” a statement said.
Nichola Clark, an ocean expert at the Pew Charitable Trusts called the long-awaited treaty text “a once-in-a-generation opportunity to protect the oceans-a major win for biodiversity”. The treaty will create a new body to manage the conservation of ocean life and establish marine-protected are-as on the high seas. Clark said that’s critical to achieving the UN Biodiversity Conference’s recent promise to protect 30 percent of the planet’s waters, for conservation. The treaty also establishes ground rules for conducting environmental impact assessments for commercial activities in the oceans.
Treaty negotiations were initially anticipated to conclude on Friday, but stretched through the night into Saturday. The making of the treaty represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany’s environment minister.

5 . I’ve been in an 18-year love-hate relationship with a black walnut tree.
It’s a unique tree. In late September or early October, falling fruits as hard as baseballs threaten the skulls (头骨) of you, your children, your neighbors and those that reside next door to them. Umbrellas in the yard are a must while dining in early August, and as for me, I wear my bike helmet while working in the garden.
The black walnut also releases a chemical substance through its roots as a competitive strategy. It’s poisonous to several common plants. There have been many new plant varieties that I brought home with hopes that maybe the black walnut would accept them, but they failed to flourish.
What does work are native plants that naturally grow in the area. Native plants are important to have around since they provide beneficial pollinators (传粉者) like birds, bees and butterflies with seeds and contribute to a healthy and biodiverse environment. Native plants for this area are generally easy to grow, so they experience less stress.
Have I thought of getting rid of this giant pain in my tiny backyard? Yes, however, getting rid of this tree standing at 50 feet with an 87-inch trunk is next to impossible. It’s also protected under the law. Rightfully so. Trees are important to the urban forest and for all of those that inhabit it.
Sometimes I think about my life without the black walnut. I can’t imagine a spring without the birds who arrive every year and loudly sing their songs before dawn. I’d miss falling asleep on lazy weekend afternoons as I look up into its leaves.
Every spring, I wonder what the season holds: What are the chances of being knocked unconscious while barbecuing? Like any good relationship, I’ll never be pleased. I’m stuck with this tree, so I’ll listen to its needs and give it the space it requires. In return, my walnut offers a habitat for wildlife and a reminder.

6 . Scientists have shown how plants can protect themselves against genetic (基因的) damage caused by environmental stresses. The growing tips of plant roots and shoots have an in-built mechanism (机制) that spells cell death if DNA damage is detected, avoiding passing on faulty DNA.
Plants have small populations of stem cells (干细胞) at the tips of their roots and shoots, which enable them to continuously grow and produce new tissues throughout their lifetime. These stem cells serve as ancestors for plant tissues and organs. However, any genetic faults present in the stem cells will continue to exist and be passed on permanently throughout the plant’s life, which could last thousands of years.
Given the critical role of stem cells and their exposure to potentially dangerous environments at the growing tips of roots and shoots, safeguards are necessary to prevent stem cell faults from becoming fixed. Researchers Nick Fulcher and Robert Sablowski, funded by the Biotechnology and Biological Sciences Research Council, aimed to uncover these protective mechanisms. Through experiments involving X-rays and chemicals, they discovered that stem cells were more sensitive to DNA damage compared to other cells.
When DNA damage occurs, the cells have the capacity to detect it and cause programmed cells to die, preventing the propagation of the damaged genetic code to the rest of the plant tissues. This process has similarities to the safeguard mechanism found in animal cells, which has been broadly studied due to its relevance in preventing cancer.
The identification of a similar protective system in plants is of great interest in the field of plant development. It also helps scientists develop plants that can better handle environmental stress. So knowledge of how plants deal with these stresses is of fundamental significance to agricultural science’s response to climate change.

8 . You look up at the sky on a clear and dark night, you’ll see more stars than your eyes can count. Most of these stars have planets, similar to our own, orbiting them. With so many celestial bodies floating out in space, you can’t help but question whether other forms of life exist in the universe. And if that’s the case, is it possible to contact them?
Science is still somewhat divided on this issue. Currently, no evidence exists to suggest that intelligent life exists elsewhere in the universe. Yet with an estimated one trillion planets in our galaxy alone, it seems highly likely that Earthlings aren’t the only intelligent creatures out there. Some claim that life can only develop under perfect circumstances, and Earth is perhaps the only example of this. Other scientists object to this claim, and point out that even on Earth, life can find a way under the most extreme circumstances.
Some people believe that aliens have already visited our planet, but this information is being kept secret by governments. The most famous incident of this kind occurred in Roswell, New Mexico in 1947. On that date, many residents reported seeing an unusual flying disc streak through the sky, before it crashed in a field. When the military heard about the crash, they quickly sealed off the area. A few hours later, the army base announced that it had recovered a flying disk. Shortly after, this statement was retracted and it was said that it was a weather balloon that crashed. However, years later one local mortician even claimed that the military had him secretly perform an autopsy on a dead alien body.
Others believe that there certainly are other life forms out there, but the distance between us is too great. Even if we could somehow create a spaceship that travels at the speed of light, it would still probably take several lifetimes to reach them. Then again, we might never have to do this if aliens reach us first.
1. Why do some scientists think there is life on other planets?| A．Because an unusual flying disc was ever witnessed. |
| B．Because life exists despite extreme conditions as those on the Earth do. |
| C．Because the government’s statement seemed suspicious. |
| D．Because there are a great number of planets in the universe. |
| A．Examined again to guarantee the correctness. | B．Emphasized again to persuade people. |
| C．Formally taken back what has been said. | D．Seriously criticized due to poor evidence |
| A．Are we alone in the universe? | B．Is it possible to contact aliens? |
| C．Intelligent life in the universe. | D．Planets floating out in space. |
| A．Objective. | B．Humorous. | C．Cautious. | D．Anxious. |
When I arrived home from school, night was falling. A call came from the public: a bird of unknown species was being attacked by a group of noisy children in his front garden. He scared them off and grabbed their victim. I immediately called for my classmate Jack to the spot.
We were standing in front of a stranger’s house in an unfamiliar street, rescue box in hand. My head full of instructions to follow. “The bird would be our first test as a volunteer wildlife rescuer!” Jack said excitedly. We had completed the two-day intensive training course the previous month and learned the basic skills of rescuing animals in various situations.
But we were anxious, too. After all, it was the first time for us to rescue a bird. Would I be able to transfer the bird neatly into my rescue box? Many worries flashed in my mind. Sensing my unease about the act ahead, Jack said, “These things are pretty easy to deal with!”
I was wondering what kind of bird it was when a kind-looking man appeared and led us inside to see our very first patient. I lifted the edge of the shoe box very slightly to see an angry-looking bird standing to attention on very thin and long legs, together with a slice of banana and a small dish of water. He didn’t know its true name but the folks called the creature Red Fan. “It’s eaten some banana,” said the man proudly. The poor soul seemed rather nervous, so l decided not to grab it by hand but just transfer the whole shoe box into my rescue box.
Back home, we could only see some minor injuries in the left wing, but there was no blood on its feathers. Jack managed to treat the injuries with some iodophor (碘伏药水). We assessed its condition to find out if it was appropriate to release the bird the next day. How could we help it spend the night peacefully? We hadn’t seen this species of bird before, let alone its habits.
