1 . 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.

A new study found that light pollution is making the night sky brighter and the stars dimmer. Man-made lighting is the main cause, making the night sky about 10 percent brighter each year.
The result was a much faster rate of change than scientists had estimated. The research team gave an example to explain the result. If a child is born where 250 stars can be seen on a clear night, by the time that child turns 18, only 100 stars will be seen.
The researchers said they had hoped to see improvements in light pollution in recent years, because many urban centers have changed their lighting to be more energy-efficient. Towns and cities are replacing older streetlights with modern LEDS that are more carefully directed downwards, where the light is useful.
The hope was that if the light was better directed, the situation would get better. But there are many types of lighting — streetlights, decorative, advertising. So, with all these things combined — and possibly more lighting overall, we are making sky brightness worse. The relatively low cost of LED lighting is also contributing to the problem, that is, the cheaper and better the lighting, the higher society’s addiction to light.
Consequently, light pollution leads to a loss of universal human experience, a source of inspiration for art, science, literature. It also affects the routine of human as well as other forms of life. Migratory songbirds normally use starlight to position where they are in the sky at night. And when sea turtle babies hatch, they use light to position toward the ocean — light pollution is a huge deal for them.
1. What causes light pollution?2. What are the negative effects of light pollution?
3. Please decide which part is false in the following statement, then underline it and explain why.
The sky brightness becomes worse because of more modern types of lighting being used and the lack of LED lighting.
4. Besides light pollution, what do you think is the most serious pollution in life? And explain its effects. (In about 40 words)
Japan started releasing nuclear-contaminated water into the Pacific Ocean on August 24th and will continue to do so for at least 30 years. In the face of strong questioning and opposition from the international community, Japan plays word games by referring to the discharged “nuclear-contaminated water” as “treated nuclear wastewater”.
However, the two are fundamentally different. Nuclear wastewater refers to the wastewater produced during the normal, daily operation of a nuclear power plant, such as large quantities of water used to cool down the reactor of the plant. Because the water doesn’t touch radioactive substances (放射性物质) in the nuclear reactor, it can be flushed out after strict processing.
Nuclear-contaminated water refers to cooling water that comes into direct contact with radioactive materials inside the reactor when the reactor is breached after a nuclear accident. The cooling water becomes contaminated with highly radioactive substances, thus becoming nuclear-contaminated water.
The Fukushima nuclear power plant experienced a major incident in 2011, bringing water into contact with radioactive substances. The Japanese side’s conflation (混淆) of this with wastewater from normal operations is a deceptive attempt to hide the truth. The Japanese side claims that the multi-nuclide treatment system ALPS is used to treat nuclear contaminated water, and that the treated water is safe and even meets drinking water standards. However, such statements fail to alleviate public concerns. Japan has yet to address major international concerns, such as the long-term reliability of the purification facility, the authenticity and accuracy of the nuclear-contaminated water data, and the effectiveness if the monitoring arrangement. This is extremely selfish and irresponsible, as the discharge will spread the risks of nuclear contamination to the rest of the world.
1. How does the Japanese mislead the international community?2. In what way nuclear-contaminated water is different from nuclear wastewater.
3. Please decide which part is false in the following statement, then underline it and explain why.
Japan’s deceptive attempts to hide the truth alleviate public concerns over the long-term reliability of the purification facility, etc.
4. How is Japan’s dumping nuclear-contaminated water related to you? (In about 40 words)
White sand beaches of the Cocos Islands, which are known as a gorgeous tourist destination surrounded by greenish blue water, have now been filled with plastic wastes.
Jennifer Lavers, a marine scientist, went to these tropical islands with her research team. Knowing that lots of beaches were polluted by plastic wastes, the team conducted a careful scientific examination on the coast, only to find the problem caused by pieces of trash humans left was worse than expected.
Not all plastics are to blame. They are necessary in places like hospitals and airplanes, and make our vehicles lighter and more efficient. However, other plastics, especially disposable(一次性的) plastics, account for the growing mess on the beaches. Islands all over the world are jammed with plastics. And the Cocos Islands are no exception.
Apparently, demand for disposable plastics must be reduced greatly. “Why don’t we carry around bags that we can use over and over again?” asked Richard Gross, a chemist who researches innovative ways to make more sustainable plastics. “Let’s carry around reusable lunch boxes. We should understand how serious the situation is.”
Although it is important for individuals to make an effort to avoid using disposable plastics, it is also generally believed that only with international rules can such a deep-rooted, common, and worldwide scourge(灾害) be tackled.
However, the U. N., which engages in dealing with accelerating climate change and public health crises, obviously isn’t paying enough attention to calling for international action on plastic pollution. As a result, billions of plastic products will still be produced every year, many of which will end up in the ocean.
It requires the greatest effort of all time to control plastic pollution in modern society. No matter how tall the hurdles(栏架) are, something has to be done.
1. What did Jennifer Lavers and her research team find?2. What kinds of plastics lead to the increasing wastes on the beaches?
3. Please decide which part is false in the following statement, then underline it and explain why.
Individual efforts and international rules are both required to tackle the plastic pollution, and the U. N. pays much attention to calling for international action.

Fashion's Melt Down
Throwaway culture is trashing the planet-but one young chemical engineer has her own way to turn it over．
Fast fashion has changed the way we dress．We buy more clothes, more often-but we wear them less．Alina Bassi, founder of Kleiderly, wants to give our clothing waste another chance at a useful life．
Bassi has always cared about the threat of climate change, but she actually started her career in the oil industry．After a few years, she landed at bio-bean, a startup that turned waste coffee grounds into products that could be burnt for heat and fuel．After a year, Bassi was keen to branch out-used coffee grounds are not the biggest threat facing the planet．Instead, she poured her efforts into tackling a much bigger global polluter: the fashion industry．
According to the Ellen MacArthur Foundation, we produce 100 billion items of clothing per year, and this is set to double by 2050．But they don't last long enough to offset（抵消）the carbon cost of producing the material, creating the clothes, and then shipping them to customers．"It makes no sense that we have such a high carbon footprint for something so short-lived," Bassi says．
Using the principles of a circular economy, Bassi has developed a low-energy, multi-stage process to turn clothing fibres into an alternative to oil-based plastic．This new plastic can then be used by manufacturers in their existing machines, so that your old T-shirts and jeans will become different products instead of clothes, such as clothing hangers, or even furniture．
Fashion companies have some other ways to reduce fashion waste, from creating clothes designed to last, to recycling the fabric to make more clothing．But "a problem this big needs multiple solutions," Bassi says．"We think about the multiple lives of a product and how we can keep reusing it instead of letting it fall into landfills or incinerators（焚化炉）,"she says．
1. Why did Bassi switch her focus to the fashion industry?2. Please paraphrase the underlined sentence in your own words．
3. Please decide which part is false in the following statement, then underline it and explain why．
Kleiderly can change old jackets and trousers into a new material, which can be used to make more clothing．
4. Please briefly present your own solution（s）to the throwaway problem in daily life．（about 40 words）
