Silk. The word itself is beautiful. The story of silk starts in China over 4,000 years ago. It is said that a cocoon(茧)fell into a woman’s tea cup. It then opened into a single thread(线). This was an important discovery. The Chinese learned they could use the cocoons of silkworms(蚕)to make clothes, both beautiful to look at and soft to touch.

Making silk was a secret in China for many years. In other countries, silk was hardly seen and valuable. Often it was worth more than gold. By the year 1 A.D., silk was sold as far west as Rome, and all along the Silk Road. It connected China with places in the Middle East and Europe. Thanks to the Silk Road, the communication between China and West was greatly improved. Centuries later, in 1522, the Spanish brought silkworms to Mexico.

Now people around the world still make many beautiful things from silk. But silk isn’t only beautiful. It looks delicate, but it’s very strong. For example, it has been used to make bicycle tires(轮胎). Silk is also light and warm. This makes it great for clothes like winter jackets.

All of this comes from a little silkworm. That is the wonder of silk.

My name is Philippe and my wife’s name is Sophie. Recently we were faced with a difficult situation while travelling by car in the mountains. It was a long ride and we were tired. Just as we wanted to rest for a short time, the engine(发动机)made a strange, loud noise and then stopped working.

The sun was just setting and the air was getting cooler. We were in a place far away, with no houses in sight. We started to hear the cries of wild animals, so Sophie was nervous. We didn’t have much food and it was getting colder, and darker.

A couple of hours passed. Suddenly, the headlights from another car appeared in the dark. A stranger got out of the car. He looked unfriendly at first, until his mouth opened with a wide, friendly smile. He asked us to get into the car with him. He had such a kind face, and we knew we could count on him.

He drove us to a village, where his cousin lived. His cousin offered us tea and local foods. Everyone was excited to have unexpected guests. Later that evening, when we prepared to leave and thanked our new friends, I couldn’t believe the reply from the cousin: “No, we thank you for coming into our home.”

I will never forget the kindness we received on that day because we turned to a complete stranger for help.

“Without music, life would be a mistake,” famous German philosopher(哲学家)Friendrich Nietzsche said over a century ago. Music is a big part of our lives. But in recent years, some US schools have cut music classes to control budgets(预算).

For example, Chicago public schools hurt arts education when it fired over 1,000 teachers. Among them, 10 percent of the teachers taught art or music, according to The Washington Times. In fact, this is not just a problem in the US. In other countries, such as China and the UK, music classes are not thought to be as important as ones like science, math and history. That’s partly because music is not seen as a very important life skill, and it isn’t tested. Many students are busy with schoolwork, so parents and students choose to focus on subjects that are tested more often.

However, learning music is beneficial(有益的)in many ways.

When playing music, you need different abilities to work together. It is not as simple as it looks, according to Kenneth Guilmartin of Music Together, an early childhood music development program. For example, when playing the piano, people see music notes and decode(解码)them in their brains. They also use their fingers to make sounds. You need to deal with all these things at the same time.

Music has a special connection with science as well. You can see that many scientists are good at playing music: Einstein played the violin, and German physicist Max Planck was talented in playing the piano.

D.Playing the piano needs people to see music notes.

We all know that we need water to live. Up to 75% of our bodies is water and we need to drink water every day to be healthy! So what will happen to the Earth’s water if global warming (全球变暖)gets worse?

About 71% of the Earth’s surface is covered with water. When the temperature of the Earth rises, the temperature of the water rises, too. Higher water temperatures will kill the underwater plants and tiny fish. But it’s not just the fish! Higher temperatures also have an influence on animals on land. Some scientists think that because of global warming, two thirds of the world’s polar bears will never be seen on our planet by 2050.

Global warming makes the weather change, too. In some places, there will be less rain. This will cause deserts to be larger. In other places, the rain will become very strong and heavy, so we will have less farmland and not enough food for humans.

Global warming is a big problem. But we can help by making small changes like turning off the water, lights, and TV when we aren’t using them!
