Every few years, humpback whales come to the water area in San Luis Obispo, California, for a few days while migrating, which attracts hundreds of visitors and whale lovers. In November 2020, over 20 whales were around, feeding on silverfish. Each one is huge, about 15 metres long.
At that time, I lived nearby and I was always crazy about whales so I invited my friend Liz Cottriel to go out on a ship to check them out the next morning.
“No way,” Liz hesitated. She was scared of whales and sharks, and was worried that the ship would overturn while we were in it. But I told her there was nothing to worry about and we probably would have an unforgettable experience.
Convinced, Liz joined me and we set off at 8:30 the next morning. For the first half hour we didn’t see anything. Then I spotted two pairs of whales, swimming towards us at fast speed. Though it was the first time we had seen the large creatures at such a close distance, we intended not to turn around immediately we met them. Instead, we chose to wait for their approaching.
One of the whales breached (跃出水面), then went down and hit the water really hard, leaving what looks like a layer of oil and also large waves.The boat started rocking wildly. At that moment, we realized it was too close.
All of a sudden, a large group of fish started jumping out of the water into our ship. Their movement sounded like cracking glass around us. I was terrified. Then I felt our ship lifted out of the water – about two metres, we later learned. I figured the whale was going to drag us down somehow, and I had no idea how deep we’d be sucked underwater.

2 . There are an extremely large number of ants worldwide. Each individual ant hardly weigh anything, but together they weigh almost the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops or around the poles. For animals their size, ants have been surprisingly successful, largely due to their wonderful social behavior.
In groups that range in size from a few hundred to tens of millions, they organize their lives with a clear distribution of labor. Even more amazing is how they achieve this level of organization. While we use sound and sight to communicate, ants depend mostly on pheromone (信息素), which is a kind of chemical released by individuals and smelled or tasted by fellow members of a group. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an ant comes under attack or is dying, it sends out an alarm pheromone to warn the whole group to prepare for a defensive fight.
In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will take on an animal much larger than themselves, attacking in large groups and beating their target. They show so much devotion to their group that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.
United and devoted, these little creatures have survived on the earth for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a united intelligence greater than you would expect from one small individual ant.

3 . Flash droughts (突发性干旱) develop fast, and when they hit at the wrong time, they can ruin a region’s agriculture. They are also becoming increasingly common as the planet warms. In a study published in the journal Communication Earth &Environment, we found that the risk of flash droughts, which can develop in a few weeks, is on pace to 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 ravage will also rise. A flash drought in the Dakotas and Montana in 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 reinforce themselves, with some help from the warming climate. When the weather is hot and dry, soil loses water rapidly. Dry air extracts moisture from the land, and rising temperature can increase this evaporative 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 (排放物) 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, respectively, by the final decades of this century. Globally, the largest projected 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.

4 . The polar research vessel (船舰) RRS Sir David Attenborough, which will always be thought of by some as Boaty McBoatface, is currently on an Antarctic task to find out how sea ice influences the cycle of nutrients and carbon in the world’s oceans.
The 12 researchers on board are using autonomous underwater vehicles to explore huge areas of free-floating sea ice. This will help us better understand how climate change is impacting organisms from microscopic plankton (浮游生物) to penguins and orcas. .
Last week, the vessel collected samples from around the A23a mega iceberg (a scientific term) . The largest iceberg in existence is almost 4, 000 sq km, equal to an area twice the size of Greater London, weighing close to a trillion metric tonnes and towering up to 1, 312 feet above the sea.
It originally broke away from a main ice shelf connected to Antarctica in 1986, but had remained stuck against the seabed ever since. Until last month. Now, A23a is drifting into the Southern Ocean.
Of course, one iceberg floating into warmer waters and melting is just the tip of the iceberg when it comes to the climate crisis. At COP28, billions and billions were promised to fund global I climate solutions, especially in developing nations. More than 130 countries agreed to deal with emissions in agriculture, with 118 promising to triple renewables too.
But more needs to be done. Forget the A23a iceberg being a threat to shipping, it’s a sign we may be all sunk.

5 . There are well-documented mental health benefits to pet ownership, as much research has shown. Indeed, we know there are some physical benefits as well, as dog owners tend to have more active lifestyles. Yet when it comes to conditions like allergies (过敏), we tend to think of pet ownership as exacerbating, not alleviating them.
Hence, a recent study published in the journal PLOS One might come as a surprise. The study, published Wednesday, found that children raised with cats and dogs early in life had a 13 to 16 % lower risk of developing all food allergies than those who did not own pets.
The researchers engaged in a detailed survey, studying 65,000 children. They found that children who were exposed to dogs either during fetal (胎儿) development, or up to the age of 3 years old were less likely to have nut, milk and egg allergies.
This wasn’t true for other pets that weren’t cats and dogs. Indeed, the same research found that children exposed to hamsters during this same period had an increased risk of nut allergies. Yet children who were exposed to cats during their early years were likewise less likely to develop specific allergies — namely, allergies to wheat, soybean and egg.
While the study is not the final word on the issue — the researchers note “further studies using oral food challenges are required to more accurately assess the incident of food allergies” — it reinforces preexisting research on the seemingly funny ways that cats influence human development.
In addition to adding to the growing body of scientific literature about pets and human health, the PLOS One also reinforces earlier research about the role of the environment in developing allergies. The research repeatedly found that exposure to farmyard dirt, dust and the various fine hairs that fly off animals helps children in their breathing system development.

7 . Workers continue to search the ruins of a large earthquake that hit Morocco Friday. Officials say almost 2,500 were killed in the quake, but that they expect that number will rise. The United Nations said the magnitude 6.8 earthquake affected 300,000 people. The damage was great because the starting point of the shaking was not far below the ground.
It is the strongest quake to hit the North African nation since 1900. And, it is reported to be the country’s deadliest since 1960, when at least 12,000 people were killed in and near the city of Agadir.
So far, Morocco has accepted support from four countries — Spain, Qatar, Great Britain and the United Arab Emirates. Other nations have offered help as well. Groups from the Moroccan army left Monday from Amizmiz to move into the small mountain villages. Heavy equipment was sent to clear the roads and both visitors and local people lined up to give blood.
Many people continued to sleep outside, fearing smaller earthquakes that often follow a major one. In the village of Imgdal, women and children gathered outside and some kept warm around an open fire on Monday morning.
On a road near the town of Adassil, near the epicenter (震中), one rescue worker, Ayman Koait, was trying to clear the rocks that were restraining trucks from getting by. He said other roads were in bad shape. “We’re trying to open them, too,” said Ayman Koait.
People said they dug through the ruins of their homes looking for relatives. They also moved rocks and walls looking for important items.
Many of the homes are made from wood, rock and mud, which made them fall easily when the ground started shaking. One military (军方的) worker said “it is difficult to pull people out alive” because the walls turned into ruins and did not leave any space for air.
1. Why was the earthquake so serious?| A．It happened close to the ground. | B．It broke out at midnight. |

8 . Cruise through many neighborhoods or parks around the world, and you will find no shortage of well-mowed expanses of grass. Lawns (草坪) do look attractive.
Why did lawns become so popular?
What environmental problems are lawns causing?
Lawns are homogenizing the environment, not only in terms of biodiversity but also visually. You compare countries’ and cities’ urban landscapes around the world, and they look exactly the same.
You have to find your own local solution. We can take inspiration from the natural plant communities around us. In suburban and rural areas, that might mean having a meadow or prairie. In other places, it might be a savanna like environment or mountain plants. You can have a “grass-free” lawn; with only low-growing plants that create the same effect as a lawn, and you can walk on it.
How can we persuade people to adopt these alternatives?
When people see them, they appreciate them and like them.
| A．So it is all about education. |
| B．What are these alternatives? |
| C．And it is understandable fondness. |
| D．What are the inspirations of lawns? |
| E．However, they choke out biodiversity. |
| F．Lawns came to be seen as a symbol of civilization and a way of life. |
| G．Lawn upkeep takes resources, fertilizer and pesticide that enter groundwater and runoff water. |
9 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.
Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.
In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.
Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

10 . Usain Bolt burned about 10kcal of energy to win his gold during the 200 metre spring final at the Olympic Games, which could roughly power an old 60W light bulb for 11 minutes. If you could make use of all the power generated by all the athletes during the Games, you would still be nowhere close to reaching the 29.5 billion Watts consumed overall by the athletes, spectators and organizers over the event. We take sport for granted, but do we ever consider its cost to the planet?
From the water required to maintain the golf course during The Masters tournament to the hundreds of flights it takes to bring football fans to a World Cup, major sports events are not helping much in the fight against global heating. What’s more, there is a lack of recognition within sport of its responsibilities and little discussion about possible solutions.
This is strange, given that the effect works both ways: the climate crisis is not just affected by sports, but it is already having a negative impact on many sports. When ice-climber Will Gadd set out to conquer the world’s glaciers, he didn’t realize it would become a race against climate change. “I thought glaciers are there forever.” When he arrived at the summit, Gadd was shocked: “The ice…wasn’t there. The things I planned to climb were gone.”
Global heating is noticeable in other sports. Amy Steel played professional netball until she suffered from heatstroke after playing in 39℃ conditions and unfortunately, the damage was permanent. Not only that, but extreme weather events made more frequent as a result of global heating mean sporting events are more often delayed or canceled. This has cost sport billions in potential earnings.
Yet sport can be a powerful motivator: it can unite whole nations behind its teams. Could sport have a role to play in driving climate awareness? Will Gadd and Amy Steel are among many athletes who think so? One thing is certain. Sport must put climate change at the top of its agenda and decarbonize at a Usain Bolt-like pace to make a difference.
