You probably don't think about soil often, but the following report may help you learn about science of soil.

What is soil made of?

Soil is made of sediments (沉积物) and humus(腐殖质). Sediment is small pieces of rock broken down over time by rain, ice, and wind. Sediment is often found in water. Humus comes from decayed(腐烂的) plants and animals. It helps give plants a lot of the food they need to grow.

How does soil form?

Over centuries, rock breaks down into very small pieces.

The rock pieces mix with humus.

The humus gets thicker and thicker over time. Soil is formed(形成)l

How are soils different?

Soils can be different colors and have different textures(质感). Texture is how the surface of an object feels. Color and texture are two features(特征) of soil.

    From the time each of my children started school, I packed their lunches. And in each lunch I packed, I included a note. Often written on a piece of small paper, it might be a thank-you for an unusual moment, a reminder of something we were happily expecting, or a bit of encouragement for the coming test or sporting event.

    In early grade school they loved their notes. But as children grow older they become self-conscious（有自我意识的）, and by the time he reached high school, my older son, Marc, informed me he no longer enjoyed my daily notes. Telling him that he no longer needed to read them but I still needed to write them, I continued until the day he graduated.

    Six years after high school graduation, Marc called and asked if he could move home for a couple of months. He had spent those years well, graduation from college, completing two internship（实习）in Washington, D.C., and finally, becoming a technical assistant in Sacramento. However, he had lived away from home except for short holiday visits. With his younger sister leaving for college, I was especially happy to have Marc back. Since I was still making lunch for his younger brother, I packed one of Marc, too. Imagine my surprise when I got a call from my 24-year-old son, asking about his lunch.

    “Did I do something wrong? Don't you love me any longer, Mom?” he asked.

    “Of course I love you, dear!” I laughingly said. “What's wrong?”

    “My note, Mom,” he answered. “Where's my note?”

    Peng Liyiian, First Lady of China, made a speech in English at the United Nations on September 26, 2015. She talked about education and shared her Chinese dream with the world.

    Peng began her speech with a story of her father. Her father grew up in a small village in China. In those days, not many villagers could read, so her father opened a night school to teach them. With his help, many people learned to write their names and read newspapers for the first time. And many women were able to teach their children how to read. Peng's father's love for education influenced her deeply. She was lucky enough to have a good education. Later, she followed her father's footsteps and became a professor of music.

    Education is important, but still, some children in China can't go to school. Peng hopes that all children can have a good education, and that is her Chinese dream.

    World Music Day is a music festival. It's on June 21st every year.

    In 1976, an American musician, Joel Cohen, suggested the idea of an all­night music celebration. He wanted the festival to happen on the longest day of the year. The idea was adopted(采用)by French Music and Dance director (舞蹈总监) Maurice Fleuret in 1981 and first took place in 1982 in France. Then the idea quickly spread(展开)to over one hundred cities around the world. The idea behind World Music Day is to promote(推广)music. This happens in two different ways. The first way is that people play their music and perform in the streets. The second way is to hold free concerts.

    Many of us can't live without music. World Music Day is more than just a festival. It's also a meeting place and a good time to put the music from each country together. The festival is popular with people in the world, and more and more people join in it.
