Ohio—Lake Erie, the smallest of North America's five Great Lakes, supplies fresh drinking water to an estimated 11 million people in Ohio, Michigan and southern Ontario province, Canada.

Yet sometimes pollution, bath from industrial waste and farm-chemical run-off, leaves large areas of the lake covered in half-meter-thick layers of green slime. Scientists blame a lot of chemicals entering the water, which has caused pollution.

To find out where these extra nutrients come from, the Ohio Department of Natural Resources has been studying data from its network of 14 water-quality monitoring stations installed along the rivers that flow into the Lake Erie basin.

At one point, water from the small stream is diverted into a pipe where it is pumped into the testing station.

We'll have 'a sample a day, year-round every day so that really pins down what the chemistry is like," says Dave Baker of Ohio's Heidelberg University, who takes charge of the monitoring stations for the Department of Natural Resources.

The U.S. Environmental Protection Agency, the federal government's pollution watchdog, requires point sources, such as factories, to monitor and report their discharges. So Baker is looking for where the other sources of pollution come from.

"If there are problems in Lake Erie, we want to know where it's coming from and make sure we're putting resources to solve the problem properly," Baker says.

In this case, a primary source of the pollution turns out to be chemical fertilizer that turn off farmland during rainstorms.

Because farmers believe fertilizers are essential to high crop yields, they would like to use them. However, the USDA's Natural Resource Conservation Service isn't asking them to abandon farm chemicals, but rather to use them more sparingly so they don't run off the land when it rains.

Another technique for reducing farm chemical pollution of Lake Erie is cover-crop farming. After the harvest, farmers plant a second quick-growing crop to reduce erosion. The deep-rooted plants, such as rye or turnips, help to cover the soil, allowing worms and fungi to work their magic and helping the soil to absorb more water and nutrients.

【推荐1】Delhi has been the centre of a succession of mighty empires and powerful kingdoms in India. Numerous ruins scattered throughout the territory offer a constant reminder of the area's history, which makes the city always be a fascinating place for tourists.

With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem.

Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has become an annual public-health emergency despite government vows to solve the problem.

Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.

New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coal-based power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states. Fireworks and firecrackers to celebrate the Hindu festival of Diwali then arrives, leaving Delhi the world's most polluted city.

The city's air quality index, which measures a mix of dangerous pollutants, registered an average score of 494 Sunday. That is the highest 24-hour average since Nov. 6, 2016, when it hit 497, according to data measured by the Central Pollution Control Board.

1. Which of the following is true?
A.Diwali, one of the festivals in India, is not important to Idians.
B.The index of the recent air pollution is not the worst in the history.
C.Dehli, once a constant reminder of the area’s history, has shrunk.
D.The government did nothing to protect its citizens against the pollution.
2. Who may not complain about the serious air pollution?

文章大意:这是一篇说明文。文章讲述了光污染形成的原因以及造成的负面影响。
【推荐2】阅读下面短文,根据文章内容及题目要求回答问题。

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.

文章大意:本文是一篇说明文。主要介绍的是个人防护装备的处置不当造成医疗废物的累积和垃圾乱扔,从而破坏生态环境。

【推荐3】During the pandemic, masks and other forms of personal protective equipment (PPE) have become familiar fixtures of our daily lives. They have helped ensure the safety of ourselves and our loved ones. Yet, the improper disposal of PPE has contributed to a hazardous trend — the accumulation of medical waste and the littering of our planet.

Every month, we use nearly 129 billion masks. In a recent report, the United Nations found that from March 2020 to November 2021, around 87,000 tons of used masks and gloves have become non-disposable waste.

This is very worrying, as the waste traps animals and affects the health of our communities. When not properly discarded (丢弃), PPE waste may be blown into local rivers and streams or mistaken by birds as materials for building nests. It is harmful to the environment because most PPE is made from plastic fibers. These fibers can never fully degrade, and instead, break down into microplastics and nanoplastics that linger in our oceans.

At present, many healthcare facilities do not have systems that can deal with the increasing amount of medical waste. As a result, facilities have resorted to burning medical waste. This can put healthcare workers at a higher risk of catching the disease, and communities near landfills (废弃物品填埋场) can be influenced by the poisonous air from the burn pits.

Instead of traditional masks, the United Nations recommends using safe, biodegradable masks or washable cloth masks as an alternative. Sealing used masks and gloves in a separate bag and cutting mask straps before throwing them away can also prevent PPE from ending up in unintended locations, such as sewage systems on streets.

However, it is important to note that masks should not be placed in household recycling bins because most garbage collection systems in cities are unable to dispose of the materials. Ultimately, knowing how to responsibly discard our PPE can help us not only protect the environment but also ourselves and other individuals in our community.

1. What does the underlined word “hazardous” in Paragraph 1 mean?
A.Welcome.B.Clear.C.Dangerous.D.Gradual.
2. What do we know about medical waste?
A.Its amount is decreasing on an annual basis.
B.Its fibers can permanently stay in the ecosystem.
C.It can be burned by healthcare workers without pollution.
D.It can be degraded by the majority of healthcare facilities.
3. What can we learn from the recommendations from the UN?
A.The components of the used masks should be recycled.
B.The used masks should be mixed with household trash.
C.The raw material of traditional masks should be reconsidered.
D.The community should build sewage systems to collect used masks.
4. What is the purpose of the text?
A.To appeal to people to recycle.B.To explain a social phenomenon.
C.To stress the importance of PPE.D.To introduce an environmental problem.
