By the end of the century, if not sooner, the world’s oceans will be bluer and greener due 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, which 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 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, which can easily affect phytoplankton growth.
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. 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.
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. Dutkiewicz said, “The change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

【推荐1】The climate change has become an issue that no one can escape from. If the world wants to limit climate change, water shortage and pollution, we all need to choose “flexitarian” diets, say scientists.
This means eating mainly plant-based food, which is one of three key steps towards a sustainable future for all in 2050, they say. Food waste will need to be halved and farming practices will also have to improve, according to the study. Without action, the impacts of the food system could increase by up to 90%. Fast on the heels of the landmark report of the Intergovernmental Panel on Climate Change(IPCC) comes this new study on how food production and consumption impact major threats to the planet.
The authors say that the food system has a number of significant environmental impacts including being a major driver of climate change, providing freshwater and reducing pollution through over use of nitrogen (氮) and phosphorus (磷).
The study says that thanks to the population and income growth expected between 2010 and2050, these impacts could grow between 50%~90%. This could push our world beyond its geographic boundaries. So when it comes to climate change, the authors looked at what they called a “flexitarian diet”.
“We can eat a range of healthy diets but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant-based,’’ said lead author Dr. Marco Springmann from the University of Oxford.
“You can go from a diet that has small amounts of animal products; some might call it a Mediterranean-based diet; we call it a flexitarian diet. We tried to stay with the most conservative one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week,” he added.
If the world moved to this type of diet, the study found that greenhouse gas emissions (排放) from agriculture would be reduced by more than half.
1. What benefit will the new diets bring to the world?A.The animals will be saved. | B.People will need more water. |
C.The climate change will stop. | D.The pollution will be controlled |
A.Eat animal products every meal. |

【推荐2】China officially informed the World Trade Organization on Tuesday that it will ban the import of 24 different types of solid waste by the end of this year as part of a campaign to deal with environmental pollution and protect people’s health.
In response to growing public concerns over the potential environmental and health danger caused by the increasing amounts of solid waste imported into the country for recycling and treatment, China passed a special law in 1995 to control imports of waste materials, such as plastics, slag from steelmaking, unsorted scrap paper and discarded textile materials.
A year later, the country published a list for solid waste imports and began implementing a permit system to control the import volumes and types of waste imported.
However, due to the lack of effective supervision(监管) and the failure of relevant departments to fulfill their duties, solid waste imports have not been effectively controlled.
So far, China is the world’s largest importer of solid waste. According to the Ministry of Environmental Protection, China imported 7.3 million metric tons of plastic waste worth $3.7 billion in 2016, accounting for 56 percent of global imports of solid waste.
Correct recycling of solid waste materials is an important part of the global economy, and moderate imports of scrap plastic, scrap paper and scrap rubber products, such as vehicle tires, can to some extent, make up for China's shortage of various raw materials.
However, the lack of supervision has resulted in the country’s severe soil and environmental worsening.
Given that China’s continuing efforts to push for industrial transformation and upgrading have resulted in a noticeable decline in the demand for the materials recycled from solid waste imports. It is right for the country to restrict such imports for the sake of the environment and public health, and to better adapt to the changed industrial structure.
1. Why will China ban the import of some waste materials?A.The amount of imported solid waste is increasing. |
B.The demand for imported solid waste is in decline. |
C.Some solid waste has damaged the environment and public health. |

【推荐3】Washing machines are one of the greatest inventions of the last few centuries.They have made life easier. Unfortunately, washing machines also contribute to the environmental issues of energy use and micro-plastics flowing into the oceans. That is why the washing machine manufacturer (制造商), Samsung, and the outdoor-wear company, Patagonia, are working together to make a change.
For Patagonia, the issue of micro-plastics has been on its mind for years — its woolen jackets release many microfibers. As for Samsung, new requirements throughout the world have forced many producers to start thinking about ways to help reduce the number of micro-plastics. There are currently more than 14 million tons of micro-plastics floating in the oceans. Though people previously think of things such as plastic bottles and fishing lines when it comes to plastics in the ocean, thousands of micro-plastics are released into seas with every wash.
The issue is a sort of catch-22. In order to reduce energy costs, manufacturers try to make their machines more efficient. These machines use hotter water and are designed to create more friction (摩擦) between the clothing in the machine. However, both of these things lead to the release of more micro-plastics. So, using Patagonia clothes as test cases, Samsung came up with a two-fold solution: One is a technology called Eco-bubbles, which creates more bubbles to make the detergent (洗涤剂) more powerful, and the other is a water purifier that can filter (过滤) out more micro-plastics.
The cooperation between the two companies is proof of how complicated protecting the environment can be. On the one hand, clothing that is well-constructed and durable is a weapon in the fight against fast fashion. On the other hand, the material used to make those clothes and the way they are washed can also add pollutants to the environment.The same goes for washing machines. There is no one-size-fits-all solution. The fight against climate change requires creative thinking and learning how to attack a problem from many angles. This will certainly lead to even more strange and fruitful cooperation between the environmentally conscious companies.

Where there has been coffee, there has been the coffeehouse. From the 15th century Middle Eastern establishments where men gathered to listen to music, play chess, and hear recitations from works of literature, to Paris' Cafe le Procope where luminaries of the French Enlightenment such as Voltaire, Rousseau, and Diderot came to enjoy a hot cup of joe, coffeehouses have traditionally served as centers of social interaction, places where people can come to relax, chat, and exchange ideas.
The modern coffee shop is modeled on the espresso and pastry-centered Italian coffeehouses that arose with the establishment of Italian-American immigrant communities in major US cities such as New York City's Little Italy and Greenwich Village, Boston's North End, and San Francisco's North Beach. New York coffee shops were often frequented by the Beats in the 1950's. It wasn't long before Seattle and other parts of the Pacific Northwest were developing coffee shops as part of a thriving counterculture scene. The Seattle-based Starbucks took this model and brought it into mainstream culture.
Although coffeehouses today continue to serve their traditional purpose as lively social hubs in many communities, they have noticeably adapted to the times. Rediscovering their purpose as centers of information exchange and communication, many coffee shops now provide their customers with internet access and newspapers. It has become extremely common to see someone sitting at a Starbucks listening to music or surfing the web on his or her laptop. Coffee stores today also maintain a fairly identifiable, yet unique aesthetic: wooden furniture and plush couches, paintings and murals drawn on walls, and soft-lighting combine to give coffee shops the cozy feeling of a home away from home.
Today, big business retail coffee shops are expanding quickly all over the world. Starbucks alone has stores in over 40 countries and plans to add more. Despite its popularity, Starbucks has been criticized and labeled by many as a blood-sucking corporate machine, driving smaller coffee shops out of business through unfair practices. This has even spawned an anti-corporate coffee counterculture, with those subscribing to this culture boycotting big business coffee chains. Increasingly popular coffee stores such as The Coffee Bean and Tea Leaf are also giving Starbucks some stiff competition. In any case, it seems pretty clear that coffee has weaved itself into the fabric of our consumer-oriented culture.

【推荐2】The entire country struggled with the never-before-seen heat of the July 2022 heatwave, but for the disabled, the heat hit even harder. The climate crisis is a threat to everyone’s health, but according to a report in 2021, people with disabilities are more vulnerable to the extreme weather events and natural disasters that result from the climate crisis.
Professor Kristie Ebi of the Centre for Health and the Global at the University of Washington, described the topic of heatwaves and disabled people as being an important issue. “Groups at higher risk during periods of high temperature include people with chronic (慢性的) medical conditions, people who take certain medications that can reduce the ability of the body to sweat, and the disabled”, notes Ebi, going on to describe the different threats that heatwaves pose to different types of disabilities. Ebi notes the difficulty people with mobility issues or blindness may have with accessing services, such as cooling shelters. Ebi also comments on the importance of making those with learning disabilities or deaf people know the dangers of high temperatures. “Some studies suggest higher rates of suicide and other mental health issues during heatwaves, requiring targeted help for those with mental disabilities,” she added.
Ailsa Speak, a disability and lifestyle blogger, experiences uncontrollable movements in the heat due to her cerebral palsy (脑瘫). “As you can imagine, when my involuntary movements increase, I get even hotter. It’s just a painful circle really.”
In the absence of a concrete set of plans for people with disabilities during the climate crisis and extreme weather events, people with disabilities continue to be at increased risk of heat-related disease.
To prevent future death and destruction, the Climate Change Committee (CCC), an independent organization tackling climate change, advocates for adaptation planning, as the temperature is set to rise further due to the climate crisis and global warming. The CCC’s 2022 report on the health risks of overheating offers adaptation options to the government to ensure that buildings are fit for future climate change. Nevertheless, the publication does not offer specific advice about people with disabilities and overheating, which thus remains to be discussed promptly and thoroughly.
1. The underlined word “vulnerable” in Paragraph 1 possibly means .A.preventive | B.delicate | C.experienced | D.adaptable |
A.Heatwaves make people with chronic diseases suffer most. |
B.The mentally disabled have no access to cooling shelters. |

【推荐3】We’ve all been in a position where life gets busy, schedules are difficult to coordinate and connecting with friends feels harder than ever. With some friendships, we may lose touch and want to reconnect. However,the more time that passes, the more uncertain it can feel if they want to hear from us.
A recent study published in the Journal of Personality and Social Psychology says it’s time to reach out. Researchers found numerous benefits when reaching out to friends and old acquaintances. Especially if you’re unsure of how well they’ll receive hearing from you. The study, led by Dr Peggy Liu, is called The Surprise of Reaching Out: Appreciated More Than We Think. In the study, researchers posed the question: Do people accurately understand how much other people value being reached out to by someone in their social circle? To answer this question, researchers carried out 13 experiments with more than 5,900 participants. In the experiments, researchers measured how much people estimated their friends or acquaintances would appreciate them reaching out versus how much those on the receiving end did appreciate it. They also examined different forms of communication-phone calls, texts, emails, notes or even small gifts—and their impact.
Over the series of experiments, experts discovered a similar trend: those reaching out significantly underestimated how much their friends would appreciate hearing from them. Plus, the more unexpected the communication was, the more the friend on the receiving end appreciated it. “People are fundamentally social beings and enjoy connecting with others,” the researchers wrote.
In fact, what made these moments of reaching out so impactful was the effort they showed—no matter the form of communication. Dr Amie Gordon, a social psychologist at the University of Michigan, emphasises the importance of small moments and making efforts in relationships in a Psychology Today article. “In a busy life, these little moments might feel just like that—little moments that don’t really matter ... But each moment we ignore is a missed opportunity to connect and build up an emotional bank of positive moments.”
The science is clear—people appreciate the effort we put into our friendships. And we greatly underestimate it. One phenomenon that may explain why those who reached out underestimated their positive impact is because of “the liking gap”. Psychologist Terri Apter writes in Psychology Today that the liking gap is a tendency to “how we often underestimate other’s responses to us”, and the reality that other people like us more than we may think.
