Plastic pollution has long been a problem, but now it has got to a new height.
Micro-plastics, plastic particles (颗粒) less than 5 millimeters, have been found on Mount Qomolangma as high as 8,440 meters above sea level, according to a recent study in One Earth, “These are the highest micro-plastics ever discovered so far,” lead writer Imogen Napper from the University of Plymouth, UK, said.
Scientists collected snow and water samples from 19 different locations from 4,200 meters above sea level all the way up to the top of Mount Qomolangma. They found micro-plastics in all the water samples and part of the snow samples. The most polluted sample was from the Base Camp in Nepal, where there are many human activities. It had 79 particles of micro-plastics per liter (升) of snow.
But how can they get there? The answer is human activities. It is climbers who bring plastic products to the mountain. Even if they don’t litter, just walking for 20 minutes or opening a bottle of water can send micro plastics into the environment.
The plastic pollution has reached the most distant places on Earth. Researchers even found a plastic bag at the deepest point in the world’s oceans—the Mariana Tench (里业纳海沟). The bag is the same as the ones commonly used in stores.
Even covered in ice, the Arctic is still polluted by plastic. A 2020 report in Nature suggests that there are 2,000 to 17,000 plastic particles per cubic meter in Arctic ice (冰芯), and between 0 to 18 plastic particles per cubic meter from the water under the ice. Experts think micro-plastics may be transported by air and then reach the North Pole in snowfall.
We don’t know the potential (潜在的) problems these plastic particles would bring to the environment and our health, said a scientist. Then what can we do? We need to turn to high technology, like using new environment-friendly materials instead of plastic when possible.

We all get bored from time to time. For most of us, boredom (无聊) is not fun.
In the past, boredom was a part of life.
It’s not that kids in the past enjoyed boredom. Just like now, people thought of it as a bad thing. The difference is that today, boredom is a lot easier to avoid (避免).
Being bored can make people get into bad habits, such as eating too much junk food.
However, if boredom is so bad, then why do some scientists say we need more of it? Well, it has something to do with our brain (大脑). Our brain needs a rest as much as our body does.
A.We have so many things to do when we’re bored. |
B.Brothers and sisters are more likely to fight when bored. |
C.But for some scientists, it sounds like a gift. |
D.When we’re bored, we’re letting our brain get some rest. |

Rivers are important. One of the most important rivers in the UK is the River Thames. It is 346 km long and it is the deepest (最深的) river in Britain. But the longest river in the UK is the River Severn. It is 354 km long.
Rivers are important to plants (植物). Many of them grow by rivers. Some animals also make their homes on the river banks. They get food from rivers. In Africa, animals such as lions and elephants go to rivers for water.
Rivers also give people food to eat and water to drink. What’s more, they give people chances (机会) to live a better life. People can go to other places by boat. Rivers give water to farms. People can build a dam (修建大坝) across a river. Then people can use the water to make electricity (电).
But there are problems with rivers. One of the problems is that rivers are getting dirty. Another is that people use too much water from rivers. We should learn about the importance of rivers.

【推荐3】One cool April 22 morning, people started the day as usual. Yet it was not a normal day. What’s so special about April 22? The answer is because it is Earth Day. People all over the world celebrate this important day. The idea of having a special day to celebrate Earth began in the 1960s. Life was very different then.
On April 22, 1970, twenty million Americans joined the first Earth Day activities. This showed that people really want to do something for the environment. Since then laws have been passed to protect the air, water, land, and animals. The vehicles (汽车) such as cars and buses you ride in must pass tests to make sure they don't cause too much pollution. Thanks to it, cars today give out about half as many bad chemicals as they did in the past.
Now the celebration has spread to other countries. More than 175 countries take part each year. Every April 22, millions of people get together to clean and protect the Earth.
A.They also celebrate how far we have come. |
B.It's healthy enough for birds, fish, and other animals. |
C.As a result, the air we breathe is cleaner than it once was. |
D.Few people talked or even thought about the environment. |
E.Rivers and lakes are also cleaner today than they were before. |
F.Many animals near and in the river come back again after that. |
Polluted air from cars, planes and factories is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog(烟雾). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
1. Rules are not enough, every person must help to fight pollution.

Transport is one of the biggest contributors(促成物)to haze. When, where, how, why and what you drive all affect air quality (质量). When one drives to work for one year, he uses as much energy as a bus rider uses in 10 years. So walk or ride your bicycle to work or school whenever possible. If necessary, you can use public transport instead of your car. Each person using public transport for a year instead of a car can save nearly a ton of pollutants, including CO2, from going into the air.
Carpooling (拼车) is another way to reduce carbon emissions (排放). Carpooling is the sharing of car journeys so that more than one person travels in a car. It immediately reduces your car’s emissions by half.
Lots of our energy supply comes from burning coal, another contributor to haze. By cutting down your electricity use, you are cutting down on haze. So you may try to reduce your use of electricity by turning off lights, using your air conditioner wisely during the summer months, or updating (更新) your electrical appliances (电器) to low-energy models. For example, you can use energy-saving lamps that require less energy and last 10 times longer than common bulbs.
1. Who should play an important role in reducing haze?
A.City cleaners. |
B.Common people. |
C.Local governments. |
A.try not to drive so much |
B.give up driving cars |
C.improve our cars |

【推荐3】Shashiyu was once a poor village in Hebei Province, but now it has changed into a rich and livable place.
In the 1940s, villagers in Shashiyu had little food and few clothes, but they had a strong wish for a better life. Zhang Guishun, encouraged his villagers to do their best to pull themselves out of poverty, “In the ancient Chinese story, why can’t we? Nobody was born to be poor?” Hearing his words, the villagers decided to make a difference.
Led by the Communist Party of China (中国共产党), the villagers carried water and soil to their village from faraway places to improve their land. From 1966 to 1971 ,they reclaimed(开垦) lots of land and greatly improved their life.
However, the village encountered a new problem two decades later as the environment became heavily polluted by chemical plants (化工厂) and mine refineries (冶炼厂), and villagers started grape cultivation, which soon became a main industry in Shashiyu.
In 2009, the city-level government invested over 1 million yuan ($152.723) to change the village’s exhibition hall into a museum in memory of development efforts made by earlier generations. After 10 years, the village was called “National Forest Village”.
Zhang said that the village started a yearly tourism festival in 2015 to attract travelers to pick grapes. “The grapes could be sold at a better price once Shashiyu becomes famous through this festival. Our villagers can then live even better lives,” he said.
