Save the world's trees

    "When it comes tothe Earth, there is no time to waste." says the Earth Day Network. And that isright. Protecting our environment is very important, and World Earth Day wascreated in 1970 to ask more people to protect our environment. On April 22, peoplearound the world celebrate Earth Day.

Every year thereis a special topic, and this year it is "Trees for the Earth", so Earth Daythis year will be all about planting trees. They are planning to plant 7.8billion trees within the next five years.

That's a biggoal, and you might wonder why trees are so important. Because they can take incarbon dioxide (CO₂) and protect the air quality(质量). CO₂ isa chemical in our atmosphere, but humans make too much of it. Each person makesabout 2.3 tons a year, which is bad for the environment.

Well guess what!Planting new trees is important because people cut down a huge number of trees.Last year, there were 3 trillion trees in the world, about 139 billion inChina. But according to China Daily, the world's total number has been almostcut in half since human civilization(文明) began. That's because 15billion trees are cut down every year.

So we need toplant more to make up for（弥补）the ones we lost. One treecan take in 21. 8 kilograms of CO₂ per year. And it's still one ofthe cheapest and best ways to get rid of CO₂.

    But don't forget that we can also help the environment by cutting down on how much energy(能源) or water we useevery day. Every little thing helps.

School Lunches from around the World

   Do you wonder what children are eating for lunch across the world? Take a look at different school lunches and learn something about kids'school lives across the world.

   In Japan, 99% of elementary school(小学)students and 82% of junior high school students eat kyushoku (school lunch). It includes a bottle of milk, a bowl of rice, usually some types of fish, a salad, some kinds of soup, usually with tofu and vegetables, and a piece of fruit.

   In the United States kids have hamburgers and chips for lunch. Those school lunches are making the kids so fat that many are unable to meet the physical fitness standards(标准). The good news is that Improving Nutrition(营养) for American's Children Act was recently passed. That will help to make school lunches more nutritional(有营养的).

   In Beijing, school lunches are usually provided from home. A food service worker picks up the fresh meals from home and sends them to schools.

Information Card

    When Paul was a boy growing up in Utah, he happened to live near a copper smelter, and the chemicals that poured out had made a wasteland out of what used to be a beautiful forest. One day a young visitor looked at this wasteland and called it an awful area. Paul knocked him down. From then on, something happened inside him.

    Years later, Paul was back in the area, and he went to the smelter office. He asked if they had any plans or if they would let him try to bring the trees back. The answer from that big industry was "No".

    Paul then went to college to study the science of plants. He told the teacher about his plans. Unfortunately his teacher says, "It will be a waste of your time to try to do it." Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn't get his idea accepted.

    Paul later got married and had some kids. But this dream would not die. And then one night he did what he could with what he had. Under the cover of darkness, he went to secretly into the wasteland and started planting.

Every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against the common sense. Slowly rabbits appeared. Later the company actually hired Paul to do what he was already doing.

    Now the place is covered with fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him so many years until his hair turned white, but he managed to keep that impossible promise he made to himself as a child.

Do you often see ants? If the weather is warm, you may see them under the stones. If it is cold, many ants will be in their house under the ground.

Most of the ants are workers. They have lots of work to do. They look for food and take care of the young ants. Each family of ants has a queen ant. The queen doesn't work at all. She is important because she lays eggs. These eggs will become new ants.

There are many kinds of ants in America. One kind of these is very strong. They can kill and eat elephants. They move in groups. They eat all the animals they meet while moving on their way. When these ants come near, people leave their homes.

My name is Lin Tao. I'm eleven. I'm a student. The girl in a hat is my sister. Her name is Lin Ying. She's eleven, too. We're twins. We look the same. We're in the same class. We are good students. We like our family.
