【推荐1】By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
What can we learn from the passage?

【推荐2】How to Improve Climate Literacy
Climate literacy is the ability to identify, understand and explain information associated with climate science.
Over the past few years, many young people and educators have pushed for the inclusion of climate literacy in national curricula. So what are the best ways in which this can be embedded within already packed school timetables?
True climate literacy must address not only the science of climate change, but also issues of climate (in)justice, including how climate change affects people and places unevenly and contributes to inequalities within and across nations.
One way to do this is through visual storytelling. Storytelling, often involving drawings and paintings, has been used by human communities to pass on knowledge or tales of caution for at least 30,000 years — as you can see from the cave painting.
One effect of storytelling is its ability to create cognitive dissonance: the mental conflict and discomfort felt when a person’s behaviour isn’t in line with their beliefs. Stories that demonstrate the consequences of not acting eco-consciously — especially if those consequences are shown visually — can be a good way to do this, leading to individuals being more likely to take climate action in their own lives or by confronting corporate activities.
A.Therefore, the teachers we worked with remarked that lessons are typically focused on the physical processes of climate change. |
B.However, at present, much of climate change education is focused on the physical aspects of climate change, often at a global scale. |
C.The next stages of our research will reflect how a separated community has come together through this journey towards climate literacy. |
D.Being climate literate allows individuals to become active participants in the fight against climate change. |
E.This collective psychological distancing means many fail to recognise the urgency of the climate crisis. |
【推荐1】Despite being connected online, no matter what state you’re from, each city still retains its own language and slang. At my public high school in Los Angeles, we had our own secret language. A party was a “yart”. A beer was a “brewsky”. If I tried to use these words in front of anyone that didn’t live in Los Angeles, they would have no idea what was going on. When I came to college and used these words around my roommate from the East Coast, she would look at me with a blank stare.
Teenagers are often blamed for pulling apart standard linguistic patterns. The way my parents used to talk isn’t the same way that teenagers talk now. But it reflects the dynamic nature of language, which evolves over time due to various influences, including generational shifts and technological advancements. Teenagers, at an age when they are actively exploring their identity and seeking to differentiate themselves from previous generations, often play a significant role in this evolution.
It’s interesting to note that people around the world all have different terms for everyday things. Last year, I came across a British show called Love Island, which is a reality show that mixes people from different parts of the U. K. in a “villa”(another word Americans don’t typically say) for about eight weeks. As a bystander, the way they talked felt so elegant and fun, but to them, it was just normal.
Whether the way we talk is regional or from online, the soul of communication lies in its power to connect people, foster understanding, and facilitate interactions that shape our personal and social lives. I have often found it’s the way we connect with the people we live around.
Why does the author mention the British show in paragraph 3?A.To demonstrate worldwide language diversity. |
B.To speak highly of British English. |
C.To recommend a reality show. |
D.To introduce everyday expressions in Britain. |
【推荐2】Exploring Earth's bodies of water has brought more awareness to the importance of protecting oceans and the animal life that calls them home. British sculptor Jason deCaires Taylor,whose artwork can be seen in multiple underwater attractions around the world, feels this is key. “Most people just see the surface of the ocean and it is hard to think of something so plain and enormous as fragile. We don't regard our oceans as sacred(神圣的)and we should.”
What is the author's attitude towards underwater tourism?
A.Neutral. | B.Supportive. | C.Cautious. | D.Disapproving. |

【推荐1】Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.

【推荐2】When Mexican scientist of the evolution of animal behavior, Laura Cuaya, moved to Hungary for her postdoctoral studies in Budapest, she brought her pet dog, Kun-kun, along for the ride. Cuaya couldn’t help noticing how locals warmed to dogs. This prompted her naturally curious scientific mind to start asking questions. “Here people are talking all the time to Kun-kun, but I always wonder if Kun-kun can recognize that people in Budapest speak Hungarian, not Spanish?” So she set out to find an answer through a scientific study.
Cuaya and her colleagues decided to use brain images from MRI scanning to shed light on her hunch. They worked with dogs of various ages that had, until the experiment, only heard their owners speak just one of the two languages, Spanish or Hungarian. Not surprisingly, getting the dogs to happily take part in the experiment took some creative coaxing and animal training! The researchers first needed to teach Kun-kun and her 17 fellow participating dogs including a labradoodle, a golden retriever and Australian shepherds, to lie still in a brain scanner. Their pet parents were always present, and they could leave the scanner at any point.
The research team played children’s book classic The Little Prince in both Spanish and Hungarian while scanning the dogs’ brains with an MRI machine. They were looking for evidence that their brains reacted differently to a familiar and unfamiliar language. The researchers also played scrambled versions of the story to find out if dogs could distinguish between speech and non-speech.
The images reveal that dogs’ brains show different patterns of activity for an unfamiliar language than for a familiar one—the first time anyone has proved, researchers say, that a non-human brain can distinguish between two languages. This means that the sounds and rhythms of a familiar language are accessible to non-humans.
Interestingly, the team also found that the brains of older dogs were more skilled at detecting speech “suggesting a role for the amount of language exposure”. They suggest that dogs have refined their ability to distinguish between human languages over the long process of domestication.
Which of the following can be the best title?
A.Dogs Can Tell Foreign Languages | B.Dog Brains Have Different Patterns |
C.Old Dogs Know More About Human Speech | D.Dogs Can Differ Speech From Non-Speech |
【推荐3】On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation-not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats: in recent times, they've also built houses on stilts (支柱) in coastal waters. "They are simply a stranger to the land," said Rodney C. Jubilado, a University of Hawaii researcher who studies the Bajau.

Ways to Help Your Community Stay Quiet
Noise pollution isn’t just annoying. It can also cause psychological problems. If you want to cut back on the noise polution in your life, taking some measures together with your community will help you and your family feel happier and healthier.
Use your car horn(喇叭)only when necessary, as a way to let someone know you are around the corner.
The terrible sound of a car’s engine is never welcome, so make sure you are not the one causing noise pollution in your community and spring to get your car repaired. Keeping your car in good, quiet working order will be appreciated by everyone who lives near you.
Keep your music down.
It might sound beautiful to you, but respect the fact that others might not feel the same way. Don’t just assume that your neighbours want to hear your favourite opera as much as you do.
Communities with more trees are quieter than those without them, since large, leafy trees can help absorb noise, so such a project is always worth your effort.
A. Don’t use your car horn unnecessarily.
B. Stay away from the noisy streets.
C.Keep your car in good working order.
D.Take part in a community tree-planting project.
A. These homes can easily collapse during earthquakes or slip and slide downhill in landslides, especially after heavy rain.
B. On the top of that, there is the added aspect of global warming. This has mainly been caused by the huge amount of carbon dioxide produced by factories and vehicles.
C. The reason why nature is beginning to turn on us is that overpopulation. The population of the world is growing at the rate of 10,000 people an hour, nearly 90 million a year.
D. The destruction of the world’s forests plays a part, too. As a result, a hotter ocean causes stronger winds. Atlantic hurricanes are 40% stronger now than they were 30 years ago.
E. Most of the growth is in the developing world. Poor people in agricultural areas often move to the cities. They build homes from whatever materials they can find.
【推荐3】We live in a town with three beaches. There are two parts less than 10 minutes’ walk from home where neighborhood children gather to play. However, what my children want to do after school is pick up a screen — any screen — and stare at it for hours. They are not alone. Today’s children spend an average of four and a half hours a day looking at screens, split between watching television and using the Internet.
In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend. A couple of years ago film-maker David Bond realised that his children, then aged five and three, were attached to screens to the point where he was able to say “chocolate” into his three-year-old son’s ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself “marketing director from Nature”. He documented his journey as he set about treating nature as a brand to be marketed to young people. The result was Project Wild Thing, a film which charts the birth of the World Network, a group of organisations with the common goal of getting children out into nature.
“Just five more minutes outdoors can make a difference,” David Bond says. “There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven, then being outdoors will be on habit for life.” His own children have got into the habit of playing outside now: “We just send them out into the garden and tell them not to come back in for a while.”
Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it. Let us get them out and let them play.
