When you think of the Arctic (北极), you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on earth. We have polluted the deepest oceans with plastic rubbish. “And now.” CNN says, “it’s the Arctic’s turn.”
German scientists have recently found microplastics in Arctic snow. Microplastics are pieces of plastic smaller than 5 millimeters. Sadly, the scientists found 1,800 pieces of microplastics per liter of (每升) snow.
How is plastic pollution reaching the Arctic?
According to scientists, it’s clear that most of the microplastics in the snow come from the air. They fall off the plastic objects and are moved by the wind, just like dust. They mix with ice in the air and fall to the ground as snow. Finding these plastics in Arctic snow means that we may breathe them in.
Are they bad for us? Scientists cannot answer this question for now, according to the WHO. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, which can be bad for our health. What’s more, earlier studies have shown that microplastics may contribute to lung cancer risk.
Microplastics have also been found in rivers and oceans around the world. Earlier research has found that they flow over long distances and into our oceans, hurting ecosystems along the way. They start in our waste water, then flow into rivers and out to the sea, where they are eaten by sea animals. If people then eat these animals, it means that we’re eating the plastic as well.

Pollution turns the air a gray color. It is very dirty. It is not good for people to breathe this dirty air.
In order to keep pollution down the state makes cars take a test every two years. This test checks to make sure the cars do not pollute the air. If a car does not pass the test the owner cannot register (登记) it.
Some car owners drive their cars even though they cannot pass the test. This is against the law. It is also very bad for the air.
People wanted to find a way to get these cars off the road. A program was started that seems to be helping. This program buys cars that cannot pass the tests or will help pay for repairs.
In order to qualify for the program a car must be drivable and the owner cannot make over a certain amount of money. This program has been helping people by giving them money to help buy better cars or fixing their old ones. It has also been helping to cut down on pollution.

【推荐2】Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage（损害；毁坏）. They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” gradually（逐渐地）destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country’s trees had been damaged by the year 1986.
Time and time again there are serious accidents that pollute the air. In 1986 there was a serious accident at a nuclear power station in Russia. A cloud of radiation flew across the whole Europe. It is said that 125,000 people died in Russia as a result of illness caused by this accident.
In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured (受伤的). Many of the injured lost their sight.

【推荐3】April 22nd is World Earth Day. It’s a day that tells us to care about our planet. The Earth faces a lot of problems.
Global warming is a very big problem in the world. It makes the Earth hot and changes the climate（气候）. It also makes the sea level（海平面）rise. If the sea level keeps rising, some places such as the Maldives, St Petersburg in Russia, and Bangkok in Thailand, may disappear under water in just a few years.
Another serious problem is water pollution. We can only use 3% of the Earth’s water. But people throw rubbish and pour dirty water into rivers and the sea. Almost 884 million people don’t have clean water to drink.
Besides, humans are using up natural resources（资源）. According to BP（英国石油公司）, there will be no coal to use on the Earth by 2158 and oil will dry up by 2050.
It’s everyone’s duty to save the Earth.

【推荐2】Eating in space is different from eating on the earth. The food that astronauts carry with them does not look like the food you eat. Some food is carried in closed bags.

He “ shoots ” hot or cold water into the food bag with a special gun. He eats the food that come in bite sizes. The astronauts puts a whole piece in his mouth at once. There can be no crumbs（碎屑）. Crumbs would float around the spaceship and get in the way. Meat and cake often come in bite sized pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth.

【推荐3】Lu Xun is one of the greatest Chinese writers of the 20th century. Besides his famous stories, he also wrote many influential articles about the living conditions of Chinese people.
Born in 1881 to a wealthy family, Lu Xun had a happy childhood. In 1893, however, his grandfather, a senior government official, was put into prison for taking money. At the same time, his father became seriously ill. From that time on, his family were no longer accepted by their relatives and friends. These early experiences greatly influenced his writing.
By the time Lu Xun arrived in Nanjing to study at university in 1899, he already believed that Chinese society had to change and become modern. In 1902 he went to study in Japan. There, he began writing articles for several Chinese student magazines. He showed a gift for writing and translating and he even wrote several books, although none was popular. He returned to China in 1909 because he was in need of money.
After working for several years as a teacher in Beijing, Lu Xun again returned to writing. In 1918, he wrote his famous short story Diary of a Madman. It was the first Chinese novel published using the everyday language that people spoke, which helped make it a great success. This, together with his novel The True Story of Ah Q （1921）, made Lu Xun a leading Chinese writer.
Although successful, Lu Xun still worried greatly about China’s future. In 1926, he moved to Shanghai and gave up writing stories in order to devote himself to what he called “pen warfare”. He then only wrote articles which called on the people to fight against the government. For this, the government stopped him from publishing any more books. He was forced to write his articles using false names.
Since his death in 1936, Lu Xun’s importance and influence have grown. Today, many of his writings are included in school textbooks and his works are read by millions around the world.
