1 . Many news reports focus on climate change these days. Extreme heat, wildfires, floods, homeless polar bears... How do you feel when reading worrying news about climate change? You may believe that people are becoming insensitive to the warming planet, accepting that it is only getting worse.
A research team at Pennsylvania State University, US, reported otherwise. To record how the news can impact people’s emotions, participants were first exposed to negative news stories about climate change for three days. They then continued to read negative news headlines for seven days. In the first three days, the participants experienced greater fear and less hope, which can potentially hurt an audience’s belief that they can do anything to tackle the problem.
However, during the seven-day-long exposure, the fear peaked and then held steady (稳定的). “We saw the opposite pattern in our second study. The more exposure people had to these threatening news stories each day, the more likely they are to think that they can make a difference in tackling climate change,” Christofer Skurka, the paper’s lead author told the Pennsylvania State University website.
According to the researchers, one possibility is that when the public hears about climate change threats, they may convince themselves that they have control over the situation. They will then believe that their actions may make a difference.
Knowing that everyone is able to help is only the first step. According to a study that analyzed information from 430 different studies, what motivates people the most to change their behavior is social comparison. For example, if a person’s neighbors follow a low-carbon lifestyle, such as driving electric cars, the person may feel social pressure and become more likely to follow this behavior. This happens because people usually judge their own behavior and follow social norms (规范). Another effective motivation is providing financial rewards to consumers, helping them save money.
“There are so many routes to our goals,” Matthew Goldberg, the co-author of the study, told Scientific American. As Goldberg pointed out, future research like this can help policymakers decide how best to encourage people to ward more climate-friendly habits.

2 . On Christmas Eve, a team of reindeer (驯鹿) will help Santa Claus deliver gifts to children all around the world. The reindeer, led by their fearless leader Rudolph, won’t be the only ones doing something special. Back in the highest Arctic, their cousins have a remarkable ability changing their eye color.
During the summer months, when the days are long and the sun is bright, reindeer’s tapetum lucidum (荧光膜), a mirror-like layer at the back of their eye, appears golden, which helps bounce the majority of light off the eyes, effectively acting like a pair of natural sunglasses. As winter comes, and the days become shorter and darker, the tapetum lucidum turns blue to absorb more light, allowing reindeer to improve their night vision and see clear in low light conditions.
With these adaptations, reindeer can adapt and thrive in one of the harshest environments on Earth. Unlike humans, reindeer can see well into the shorter Ultra Violet (UV) range. This UV vision enables them to spot food and predators more effectively in the snowy landscape. Lichens, a key part of their winter diet, absorb UV, so they show up dark against UV-reflecting white snow. Wolf and polar bear fur also absorb UV, so instead of disappearing against snow they pop out in high contrast, allowing reindeer to spot potential threats from a distance.
Reindeer change their eyes by adjusting their tapetum lucidum, which is made of collagen fibers. In winter, the collagen fibers become packed tighter, causing the tapetum lucidum to mainly reflect blue light. This change happens when reindeer dilate their pupils (瞳孔). In summer, the reindeer’s pupils return to a smaller size, which helps reindeer reduce the amount of light entering the eye.
But their unique adaptation may hurt them. Today, the increasing use of artificial lighting, especially during the winter months, poses a potential threat to their sensitive eyes. It can make reindeer lose their way, affecting their ability to survive in their challenging environment. So it is crucial for us to be mindful of our use of electricity and make efforts to minimize light pollution to ensure the well-being and survival of these magnificent creatures.

As a human in the 21st-century industrialized world, there’s a good chance that microplastics are pumping around in your veins(静脉), as indicated by a small first-of-its-kind study in Environment International.
According to a report on the study, scientists from Vrije University Amsterdam recently developed a method to

5 . Naturalist Enzo Suma, who is now 40, lives in Puglia, a region in southern Italy whose long coastline faces the Adriatic Sea. Floating waste accumulates in this relatively enclosed part of the Mediterranean, unlike the open ocean, where the waste tends to be spread over a vast area. Feeling concerned about that, Suma makes it a habit to pick up the washed-up waste along the shore, especially after big winter storms.
One day, Suma was walking along the beach near his home when he discovered a bottle of Coke. Suma noticed on the bottle that the price, clearly printed on the bottom, was in lire, a currency (货币) that hadn’t been used in Italy since it was replaced by the euro in 2002. Could a plastic container have well survived in the Mediterranean, he wondered, for about two decades?
That led him to founding the Archeoplastica museum. It has a collection of about 500 unique pieces recovered from Italian shores and the Coke bottle is the first one of them. All collection demonstrates the unsettling life force of plastic waste in the environment. “Seeing that a product people may have used 30, 40, or 50 years ago remains still unchanged, you’ll feel different. It’s a great shock,” Suma said to a reporter. So Suma often exhibits selected pieces from the Archeoplastica collection at local schools around his hometown of Ostuni.
“The playful side of the work allows you to arrive at the less beautiful side of things,” Suma acknowledged. “Plastic is a kind of useful substance. But it’s unthinkable that a water bottle, made from a material designed to last so long, can be used for just a few days—or even minutes—before becoming garbage. Clean the beaches. Clean the oceans. Recycle. But if we are still throwing out plastics, none of those are going to be long-term solutions.”

6 . A newly published study shows that chess players perform objectively worse and — make more suboptimal (次最优的) moves when there is more fine particulate matter (颗粒物) in the air.
“We find that when individuals are exposed to higher levels of air pollution, they make more mistakes, and they make larger mistakes,” says Juan Palacios, a co-author of a newly published paper detailing the study’s findings.
Scholars have produced many studies exploring the effects of air pollution on cognition. The current study adds to that literature by analyzing the subject in a particularly controlled setting. The scholars used three web-connected sensors inside the tournament venue to measure carbon dioxide, PM2.5 concentrations, and temperature, all of which, can, be affected by external conditions, even in an indoor setting.
To evaluate the matter of performance of players, meanwhile, the scholars used software programs that assess each move made in each chess match, identify optimal decisions, and flag significant errors. During the tournaments, the researchers examined and ruled out alternate potential explanations for the dip in player performance, such as increased noise. They also found that carbon dioxide and temperature changes did not correspond to performance changes. Ultimately, the analysis confirms that the findings are driven by the direct exposure to air particles.
The researchers also found that when air pollution was worse, the chess, players performed even more poorly when under time constraints. The tourmament rules required that 40 moves had to be made within 110 minutes; for moves 31-40 in all, the matches, an air pollution, increase of 10 micro-grams per cubic meter led to an increased probability of error of 3.2 percent, with the magnitude of those errors increasing by 17.3 percent. And while the focus of this particular study is tightly focused on chess players, the findings have strong implications for high-skilled office workers.

7 . We all have an idea about the common types of environmental problems. However, light pollution may be a new term to many of us. But, the fact is that it does affect mankind, other living forms and the environment as a whole.
What is light pollution? It presents all forms of misused man-made light. The obvious cause of light pollution is the use of outdoor lighting products improperly. It can be office lighting, car headlights, station lights, streetlights and many more.
Light pollution is harmful to both animals and plants. Upon studies, it is found that obvious effects are observed in the behaviour of animals that are active at night. Needless to mention, bright light at night makes it difficult for these animals to hunt, wander and perform their regular activities. Light pollution is directly or indirectly responsible for causing several diseases. Its effects are related to disturbance in the physical rhythm (节奏). It contributes to risks of developing cancerous cells. So, it’s nothing less than a threat to human health.
You have already seen the negative effects of light pollution on animals and human health. Apart from this, the actual cost of misused light is about millions of dollars every year. It also leads to the release of greenhouse gases and global warming. After all, coal or gas is used for producing electricity.
While outdoor lighting and using man-made lighting products are part of our modern lifestyle, some simple ways will surely help in reducing light pollution. For example, while installing (安装) outdoor lighting, make sure that they are pointed downwards. Also, use only the required lighting equipment for both home and offices. Believe it or not, many people living in the urban areas cannot view clear sky and stars at night. Let’s contribute our part in reducing the pollution.

B.It contributes to most cancers. |
C.It is a negative fruit of light technology. |
D.It affects animals’ behavior during the day. |

A.Citizens should be banned to install outdoor lighting. |
B.Only simple ways can help reduce light pollution. |
C.There is no clear sky or stars over the urban areas. |
D.Light pollution needs to be dealt with urgently. |
8 . There are many kinds of pollution, which can be classified by environment, including air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollution, such as noise pollution, light pollution and plastic pollution. Pollution of all kinds may not only have negative effects on the environment and wildlife, but also do harm to human health and well-being.
Although environmental pollution can be caused by natural events such as forest fires and active volcanoes, use of the word “pollution” generally means that the wastes have an anthropocentric source—that is, a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place. Indeed, ancient human settlements are frequently recognized by their wastes, Pollution was not a serious problem as long as there was enough space available for each individual or group. However, with the establishment of permanent settlements by great numbers of people, pollution became a problem, and it has remained one ever since.
By the middle of the 20th century, an awareness of the need to protect air, water, and land environments from pollution had developed among the general public. In particular, the publication in 1962 of Rachel Carson’s book Silent Spring focused attention on environmental damage caused by improper use of pesticides such as DDT. In response, major pieces of environmental law and regulation were passed in many countries to control the environmental pollution.
Great efforts are made to limit the release of harmful substances into the environment. Unfortunately, attempts at pollution control are surpassed by the scale of the problem, especially in less-developed countries. Noxious levels of air pollution are common in large cities. To control the pollution completely, we still have a long way to go.

9 . Conifers (针叶树) are generally better than broad-leaved trees at purifying air from pollutants. But deciduous (落叶的) trees may be better at taking in particle-bound pollution. A new study led by the University of Gothenburg shows that the best trees for air purification depend on the type of pollutants involved.
Trees and other greener in cities provide many benefits that are important for the well-being of residents. Leaves and needled on trees filter air pollutants and reduce exposure to poisonous substance in the air. But which trees purify the air most effectively? Researchers from the University of Gothenburg have collected leaves and needle from eleven different trees growing in the same place in the Gothenburg Botanical Garden (GBG) to analyse which cub-stances they have absorbed.
“This tree collection provided a unique opportunity to test many different species of trees with similar environmental conditions and exposure to air pollutants,” said Jenny Klingberg, a researcher of the GBG
A total of 32 different pollutants were analysed, some of which are bound to articles of various sizes. Others are gaseous. This project has focused on paths (多环芳烃). In cities, traffic is the biggest source of these pollutants, which are released due to incomplete burning in engines.
“Our analysis show that different species of trees have different abilities to absorb air pollutants. Conifers generally absorb morn gaseous paths than broad-leaved trees. Another advantage of conifers is that they also act as air purifies in winter, when air pollution is usually at its highest,” said Jenny Klingberg.
“This study contributes to improving our understanding of the ability of trees to clean the air and which species are best at absorbing air pollutants,” said Jenny Klingberg. This known-edge is important for urban planning when designing sustainable cities. While trees and green-era can contribute to better air quality in cities, at the end of the day, the most important measure is to reduce emissions.
1. Which is the determining factor in choosing the most suitable tries to purify air?A.Air quality. | B.Geographical location. | C.The height of plants. | D.The kind of pollutants. |
A.To compare their shapes. | B.To create a tree collection. |

A.Decreasing emissions. | B.Planting more conifers. |
C.Raising public awareness. | D.Designing sustainable cities. |
10 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”
Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.
The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.
“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.
