There are forests and rivers, mountains and fields.     2    .

There are many different plants. Some are large. Some are small.     3    . There are different animals on Earth too. Some live on the land. Some fly in the sky. Some live under the water.

There are also many people like you and me on Earth. The Earth provides us with air, water and food. It is our home.

Today, there is a lot of pollution.     4    . This pollutes the air. We put our rubbish into the sea and under the ground. This pollutes the Earth and kills animals and plants.

We must stop doing these things.     5    .

【推荐2】Masks (口罩) that help save lives during COVID-19 bring a great danger to wild animals. Single-use (一次性的) masks have been thrown away across the streets, waterways and beaches. They are harmful to the environment and the animals.

In Malaysia, monkeys have been found biting the straps (带子) of used masks in the mountains, which may cause them to lose their breath or even die. There is a similar case. In Britain, a sea gull’s legs have been found tangled (缠住的) by the mask for almost one week.

It is thought that the biggest influence may be in the water. More than 1.5 billion masks made their way into the world’s oceans last year, resulting in around 6,200 tons of plastic pollution in the oceans, which may enter the food chains and influence the whole ecosystem.

Scientists suggest that the public should use and deal with single-use masks properly and cut the straps to reduce the risk (风险) of animals eating them. People are also encouraged to use washable masks.

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 boost the risk of lung cancer.

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 wastewater, 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.

【推荐1】A child's world is the world of playing. They love being outside in the open air, running after each other, and swinging on playground equipment.

But children at St. James Children's School also add to that fun by watching worms and picking up trash（垃圾） in the schoolyard. Inside, they learn to save water and electricity. They also recycle and reuse useful things. And every spring they get the soil ready to plant flowers and vegetables in the school’s garden.

Rebecca Boker teaches the children the importance of taking care of the Earth. "If children learn it early on, it will become part of their daily lives. It should be something that everyone does." said Boker “Every day at St. James is Earth Day. Most books in the classrooms and the library contain materials that encourage children to do something to protect the environment and the Earth.”

"This is their home. You are visitors in their home. So it is your job to respect their home just like you want others to respect your home and treat your home nicely."

At St. James, children observe（观察） the growth of plants from seeds to flowers in cups kept in the classroom. Then they watch the plants grow after placing them in the garden. The students also observe the life of butterflies and other insects and learn about rain and sea life.

St. James also has a special rain garden when many recycled materials are used. For example, there are rugs（小地毯） made of recycled tires in all the classrooms.

But do these very young children really get the message that their teachers try to express? Ms. Boker says yes.

"Oh they do. They totally understand."

【推荐3】Tea is an important part of Chinese tradition. Tea has a very close relationship to Chinese culture.

It is said that Chinese tea was discovered by King Shen Nong. People say that he lived 5,000 years ago. One summer day, while he was visiting a faraway part of his country, he felt very thirsty.

The servant(仆人) began to make water hot enough to turn into gas (气体) for him to drink. Dried leaves from a near plant fell into the water. The king drank some, and found it could make him feel less tired. Also as a scientist, Shen Nong was interested in the new drink. And so, tea was created in 2737 BC.

Drinking tea has many advantages. It makes people feel less tired, clears heat inside the human body and helps people lose weight. As you add a cup of tea to your daily life, please check the following helpful advice.

◆Drink it hot. Tea oxidizes (氧化) quickly, so it is suggested that you drink it hot.

◆Do not drink too much strong tea. It will probably be harmful to your stomach and make you feel sick if you make the tea too strong.

◆ The best time to drink tea is between meals. It may not make you have a strong wish to eat when your stomach is full.

◆Do not drink tea with medicine. It may change the medical result. You can drink tea two hours after you take medicine.

◆ Green tea is the best choice for office workers. Why? Because green tea helps stop the bad result of the computer.
