Earth's oceans are changing color and climate breakdown is probably to blame, according to a research.The deep blue sea is actually becoming steadily greener over time, according to the study, with areas in the low latitudes(纬度) near the equator especially affected.
“The reason why we care about this is not that we care about the color, but that the color is a reflection of the changes in the state of the ecosystem,” said BB Cael, a scientist and author of the study published in Nature.
The previous research focused on changes in the greenness of the ocean to learn about trends in the changing climate.But Cael's team pored_over 20 years of observations by NASA's ModisAqua satellite, a comprehensive database, and looked for patterns of change in the ocean's color through a fuller color spectrum(色谱) including red and blue.
The changes have been detected in over 56% of the world's oceans.In most areas there's a clear “greening effect”, Cael said, but he added that there are also places where red or blue colorings are rising or falling.“These are not massive ecosystemdestroying changes.They may be mild,” said Cael.“But this gives us an additional piece of evidence that human activity is likely affecting large parts of the global biosphere(生物圈) in a way that we haven't been able to understand.”
Although this discovery firmly documents another consequence of a changing climate, what is not yet clear is how strong these changes are and what is happening inside the ocean to cause them, according to Michael J Behrenfeld, a researcher of ocean productivity, who was not involved in the research.
NASA will be launching an advanced satellite mission in January 2024 called Pace which will also measure hundreds of colors in the ocean instead of a handful, progressing studies like these further.“Making more meaningful inferences about what the changes actually are is definitely a big next step,” said Cael.
1.Why should attention be drawn to the changing color of oceans?
A.It reflects ecosystem changes.
B.It causes climate breakdown.
C.Human activities are affected.
D.Low latitude areas are influenced.
2.What does the underlined phrase “pored_over” in Paragraph 3 probably mean?
A.Copied. B.Covered.
C.Studied. D.Borrowed.
3.What is Michael's attitude towards the discovery?
A.Unclear. B.Dismissive.
C.Objective. D.Indifferent.
4.What is the last paragraph mainly about?
A.Pace's function.
B.Cael's suggestions.
C.Meaningful inferences.
D.NASA's further research plans.
【语篇解读】本文是一篇说明文。研究表明,海洋的颜色正在变化。文章介绍了海洋颜色发生变化的原因及其给我们的启示。
1.A [解析]细节理解题。根据第二段中的“The reason why we care about this is not that we care about the color, but that the color is a reflection of the changes in the state of the ecosystem”可知,关注颜色是因为颜色反映了生态系统状态的变化。故选A。

(2025·广西河池模拟)Boomerang kids refer to adult children who return to their parents' homes after moving out. In July 2020, 52% of young adults in the US lived with one or both of their parents—the highest percentage the US has seen since 1940. In the UK, the number of single, 20 to 34yearolds living with their parents went up by 55% from 2008 to 2017.
There are many reasons for young people to move back home, says Hipplewith, a family expert. The primary reason is the high cost of living. Everything is so expensive. Staying home means financial support from family as they prepare for starting a career. Usually being a boomeranger is just a transitional period. But it still may last many months or even years to enable boomerangers to establish themselves in a career without worrying about things like rents.
For many, a return to home after living away can feel like a regression(倒退) and loss of recently won independence. “For example, you learn to become an adult in university,” says Hipplewith. “You have friends. You can do what you want to do. But now you're coming back under someone else's rule.” This can come with anxiety. Still, there are benefits to the boomerangers, say experts. Many of these adults are finding the increased ability to do work they find meaningful, rather than take a job that simply pays the bills. Socially, boomerang kids also have a good opportunity to strengthen relationships with their parents.
In many cultures, moving away from home has traditionally been considered a crucial step in becoming an adult. Now it's time to change the idea. Adulthood is really just being old enough to take responsibilities; that doesn't go away if you move in with parents again. Hipplewith hopes that as being a boomeranger becomes more common, young adults will feel less pressure to follow traditional expectations of moving out. He encourages young people to view a return to home as “sane decisionmaking”.
5.How does the author lead in the topic of the text?
A.By analyzing reasons.
B.By raising a viewpoint.
C.By telling the difference.
D.By presenting a phenomenon.
6.What is the basic cause of young adults' living at home?
A.To buy something expensive.
B.To look after family members.
C.To hunt for the right career easily.
D.To reduce economic pressure.
7.Why do young people probably feel anxious about returning home?
A.Because of the limit of keeping in with friends.
B.Because of the loss of independence.
C.Because of many years of staying at home.
D.Because of the anxiety about the future life.
8.What does the underlined word “sane” mean in the last paragraph?
A.Stupid. B.Rapid.
C.Reasonable. D.Independent.
【语篇解读】本文是一篇说明文。近年来在一些西方国家,很多年轻人选择做“回巢族”,本文就此现象分析了背后的原因及其利弊。
5.D [解析]推理判断题。根据第一段可推知,作者通过呈现英、美两国的数据揭示回巢现象,引出话题。故选D。
6.D [解析]细节理解题。根据第二段中的“There are many reasons for young people to move back home, says Hipplewith, a family expert. The primary reason is the high cost of living.Everything is so expensive.”可知,年轻人回巢的主要目的是减轻经济方面的压力。故选D。
7.B [解析]细节理解题。根据第三段中的“For many, a return to home after living away can feel like ... come with anxiety.”可知,年轻人可能感到焦虑是因为重返家里这件事让他们失去了独立性,不能随心所欲了。故选B。
8.C [解析]词义猜测题。根据画线词所在句的上文“Adulthood is really just being old enough to take responsibilities; that doesn't go away if you move in with parents again.”可知,成年这件事不会因为搬回家与父母同住而改变,我们应该理智地看待回巢这件事;再结合画线词的上文He encourages young people to view a return to home as可推知,Hipplewith觉得回巢实际上是合乎情理的决定,画线词的意思应该是“合乎情理的,明智的”,与reasonable的意思最为接近。故选C。
