2 . Nuclear pollution has long been a global concern, with major accidents like those at Three Mile Island, Chernobyl, and Fukushima highlighting the serious health and environmental risks associated with nuclear disasters. These incidents not only caused immediate health issues such as radiation sickness and increased cancer rates but also led to long-term environmental damage and genetic mutations in affected populations. Consequently, nuclear pollution remains a significant worry for governments, academics, and society worldwide.
When nuclear accidents occur near coastlines, the marine environment becomes a key point due to the vital role oceans play in climate regulation, food security, and supporting billions of livelihoods globally. In recent years, escalating threats to marine ecosystems from mounting ocean pollution have spurred increased public awareness of marine environmental protection. Studies have shown that human activities pose a significant threat to marine environments, emphasizing the need for improved environmental governance and measures to address environmental risks.
Following the Fukushima nuclear disaster in 2011, efforts to cool the reactors by injecting seawater led to the accumulation of a vast amount of nuclear waste within the Fukushima Nuclear Power Plant’s water storage tower. Despite attempts to manage this waste, the Japanese government’s decision to discharge nearly 1.26 million tons of nuclear wastewater into the Pacific Ocean over the next 40 years has faced opposition from neighboring countries, Japanese residents, and international environmental organizations.
This discharge poses substantial risks to marine life, fisheries, and human health. Radioactive isotopes (放射性同位素) such as tritium, carbon-14, cobalt-60, and strontium-90 present in the wastewater can accumulate in marine organisms, ultimately affecting human populations through the food chain. Therefore, further research and mitigation measures to address the wide-ranging consequences of nuclear pollution on the environment and human health are urgently needed.
In conclusion, while nuclear power may offer benefits, the potential risks, as highlighted by incidents like Fukushima, underscore the importance of stringent safety measures and thorough consideration of environmental impacts.

3 . Water companies have pumped waste water into Britain’s seas and rivers for more than nine million hours since 2016, new data suggests. The figure is an increase of 2,553% over five years, according to Environment Agency (EA) data, so the EA warned holidaymakers to avoid dozens of beaches across England and Wales this week.
Untreated waste water was spotted pouring into the sea near Bexhill, East Sussex on Wednesday. On Saturday, the red flags were removed, meaning the water was officially considered safe to bathe in. The beach, however, was nearly deserted.
Rachel Streeter moved to Bexhill in 2007 to enjoy wild swimming and the beach. “Flies actually flew above the surface of the water as well as the waste water. It’s quite horrible,” she said. Rachel says her friends and family have all become sick after swimming. Her 79-year-old mother went for a swim last week and fell ill with “a severe bacterial infection (感染)”.
Businesses say they are being affected by it too. Cliff Meadon, who runs business in the sea, says he has lost “thousands” pounds over the last two years due to water pollution. “We’ve been on the water with groups when we’ve had to come in as the waste comes out,” he said.
In Hastings people were advised not to swim due to a pollution risk this week. Beaches in Normans Bay as well as Bexhill were closed but have now reopened.
Southern Water argued that the water company had not been deliberately (故意的) pouring untreated water into the sea. A spokesperson for the company said, “This week’s heavy rain has fallen onto dry ground that can’t absorb surface run-off, meaning that more rain than usual has entered our waterway networks. This led to some overflows, spilling some untreated water into the sea.”
Southern Water was fined £90 million last year for widespread pollution after sending out more than 6,000 untreated waste water.

4 . REDUCING WATER POLLUTION IN THE LI RIVER
The beautiful Li River and its amazing surrounding scenery is one of the most well-known tourist destinations in Chinas Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects on the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.
Previously, water quality in the Li River had suffered greatly from an increasing volume of tourists, many of whom frequently threw garbage into the river. Many tour boats contributed to the problem too. Kitchens on board were using lots of oil. which was often thrown into the water. The growth in tourism also meant the local population rose rapidly, as well as the number of commercial and industrial enterprises. Water pollution levels increased, with more household and commercial waste ending up in the river. In order to feed more people, more chemicals were used to increase crop production. These chemicals led to severe water quality issues, causing a decrease in the number of fish species. Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore the rivers original beauty
A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation. The collection and transport of household waste was also improved. Dozens of polluting enterprises were closed or moved. The local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental awareness and encourage greater use of clean energy. At the same time, they started to carry out inspections regularly and fine tourist organisations for abuses. With these measures, it is believed that the beauty of the Li River will be preserved for generations to come.
In addition, the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives, such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, Chinas waterways are heading towards a clean and sustainable future.

6 . There are a lot of chemicals that can cause indoor air pollution. A recent project conducted has found over 900 different substances in our home are related to it. Many researchers have already examined the causes of indoor air pollution.
It has been proved that different kinds of chemicals can be released by building materials and new furniture. Everything from painting and decorating products, bathroom cleaners and beauty products can contain these chemicals.
As a research from Denmark has highlighted, cooking, particularly roasting can damage our body. Roast dinners contain many potentially harmful pollutants.
As far as cooking emissions are concerned, no one is suggesting switching to takeaways.

7 . A carbon capturing device, called Orca, began operating in Iceland in September. The machine was invented and made by a Swiss company called Climeworks. The name comes from the Icelandic word orka which means energy.
Orca can pull carbon dioxide out of the air and send it deep into the ground, where it is turned into stone. The device is made up of four sections which look like giant air conditioners stacked together. Each section contains 12 large fans that suck air from outside into steel compartments.
Inside, the air passes through a filter (过滤器) which gathers the carbon dioxide. It is then heated to a high temperature so the carbon dioxide can be collected from the filter. Then, the carbon dioxide is mixed with water and put deep in the ground into a type of rock called basalt. Basalt causes the carbon dioxide mixture to turn into stone after two or three years.
Orca is an experimental device. It was built to demonstrate that it is possible to permanently remove carbon dioxide from the atmosphere. It can remove 4, 000 metric tons of carbon dioxide from the air each year. That’s about the same amount as the emissions produced by 850 cars in a year. In order to remove enough carbon dioxide to make a big difference to global warming, much larger devices like Orca would have to be built in many countries around the world.
Some environmental activists say governments should spend more time and money on reducing the amount of greenhouse gas we produce each year, instead of investing in carbon capture methods. But others say that, in order for countries to meet their goal of net zero emissions by 2050, they will need to do both: reduce new emissions and remove the carbon dioxide already in the air.
How does Orca work?
a. Sucking the air. b. Collecting the carbon dioxide.
c. Mixing with water. d. Filtering and heating.
e. Putting into the ground.

8 . Composite image of Europe and North Africa at night, 2016. Credit: NASA Earth Observatory images by Joshua Stevens, using Suomi NPP VIIRS data from Miguel Román, NASA’s Goddard Space Flight Center. Artificial light is often seen as a sign of progress: the march of civilization shines a light in the dark; it takes back the night; it illuminates. But a chorus of scientists and advocates argues that unnaturally bright nights are bad not just for astronomers but also for nocturnal (夜间活动的) animals and even for human health.
Now research shows the night is getting even brighter. From 2012 to 2016 the earth’s artificially lit area expanded by an estimated 2.2 percent a year (map), according to a study published last November in Science Advances. Even that increase may understate the problem, however. The measurement excludes light from most of the energy-efficient LED lamps that have been replacing sodium-vapor technology in cities all over the world, says lead study author Christopher Kyba, a postdoctoral researcher at the German Research Center for Geosciences in Potsdam.
The new data came from a NASA satellite instrument called the Visible Infrared Imaging Radiometer Suite (VIIRS). It can measure long-wavelengths of light, such as those produced by traditional yellow-and-orange sodium-vapor street lamps. But VIIRS cannot see the short-wavelength blue light produced by white LEDs. This light has been shown to disrupt human sleep cycles and nocturnal animals’ behavior.

The team believes the ongoing switch to LEDs caused already bright countries such as Italy, the Netherlands, Spain and the U.S. To register as having stable levels of illumination in the VIIRS data. In contrast, most nations in South America, Africa and Asia brightened, suggesting increases in the use of traditional lighting. Australia actually appeared to lose lit area—but the researchers say that is because wildfires skewed the data.
“The fact that VIIRS finds an increase (in many countries), despite its blindness in the part of the spectrum that increased more, is very sad,” says FabioFalchi, a researcher at Italy’s Light Pollution Science and Technology Institute, who did not participate in the study. In 2016 Falchi, along with Kyba and several other members of his research team, published a global atlas of artificial lighting that showed one third of the world’s population currently lives under skies too bright to see the Milky Way at night.
The data also cast doubt on the idea that the LED lighting revolution will lead to energy cost savings. Between 2012 and 2016 the median nation pumped out 15 percent more long-wavelength light as its GDP increased by 13 percent. And overall, countries’ total light production correlated with their GDP. In other words, Kyba says, “we buy as much light as we are willing to spend money on.”

| B．Artificial light is often seen as a sign of progress. |
| C．The increase in GDP is due to the increase in light. |

9 . Ocean Noise Pollution
Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝) measured in water are different from those measured on land. A noise of 120 decibels on land causes pain to human ears. In water, a decibel level of 195 would have the same effect.
Some scientists have proposed setting a noise limit of 120 decibels in oceans. They have observed that noises above that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed (流血) and become infected (感染).
Many researchers whose work depends on ocean sounds object to a limit of 120 decibels. They say such a limit is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
1. According to the passage, which of the following is increasingly dangerous to sea creatures?| A．The sound of a car. |
| B．The sound of voices. |
| C．Manmade noise pollution. |
| D．The sound of steps. |

| A．They won’t be confused by noises. |
| B．They are deaf to noises. |
| C．Their ability to reproduce will be lowered by high level noises. |
| D．Their hearing will be damaged by high level noises. |
| A．They will work hard to reduce ocean noise pollution. |
| B．They will protect animals from harmful noises. |
| C．They will try to set a limit of 120 decibels. |
| D．They will study the effect of ocean noise pollution. |
10 . Around 40 million tonnes of electronic waste, known as e-waste, is produced every year. This includes electrical or electronic equipment that has been discarded. But where does it all go? In the US alone, 100 million mobile phones, 41 million computers and over 20 million televisions are thrown into landfills in a year. Even for standard waste this is a big headache, because any materials that are buried in the ground can’t be easily recovered and recycled. Recycling electronics can save energy and means that less of Earth’s natural resources need to be mined.
Failing to recycle e-waste is extremely damaging the environment due to the nature of the materials used in modern devices. While heavy metals and chemicals improve a device’s safety and user experience, these components become poisonous if they’re not dealt with properly. Your old phones, Gameboys, kettles, microwaves and more can end up in landfills, leaking their harmful contents into the soil, water and air. Not only does this kill wildlife and destroy ecosystems, but the accumulation of poison can impact human health too. As heavy metals and chemicals flow into lakes and rivers, drinking water becomes polluted. These poisons spread through the soil, impacting the health of crops and animals that people also rely on.
In some western countries, e-waste isn’t hidden out of sight in landfills but is burnt in giant, open junkyards. They even ship waste electronics to other countries to deal with, and this often ends up in dumps across Africa and Asia. Workers in these places are exposed to polluted lands and chemical gas.
It is urgent that we should reduce the damaging and unsustainable side of e-waste production. Rare earth metals, some plastics and chemicals can be fed into the next generation of electronics. The steps to proper recycling of e-waste are extensive and need large investment, but more and more countries around the world are turning to e-waste recycling.
