According to a new survey, students' safety has become a big problem. Nearly 50% of students say they are worried about robbery on the way to and from school. Now in main big cities in China, some schools have taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.

      Chen Haoyu, a teacher at Beijing No. 25 Middle School, gives young students advice on how to deal with danger.

★If you are robbed

     Keep calm. lf you can not cry for help or run away. Give the robber your money. Try to remember what the robber looks like and tell the police later.

★If you are in a traffic accident

     If a car hits you. You should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. This is because you don't know how seriously you are hurt

★If it is raining hard and there is lighting

    Don't stay in high places and stay away from trees.

★When there is a fire

    Get away as fast as yon can. Put wet things on your body and try to find an exit. Do not take the lift.

★If someone is drowning

     If you can't swim, don't get into the water. Cry out for help.

      Remember that danger is never as far away as you think. Take care of yourself at all time!

    Alsten Chase has written a book about Yellowstone National Park. He is worried about the damage the fires can do to the park. He is also concerned(关心) about the park rules. These rules say that nature should decide what happens to the park. Alsten also writes that the elk herd(马鹿群) has grown too big. The elks walk on the riverbanks. They eat the new grass and roots of baby trees. The beavers(河狸) need the trees to build dams(坝).

    The dams raise the water levels. Higher water levels put more water into the soil. Wet soil helps plants grow faster. The plants offer homes and food to other animals.

    Chase thinks that the park rules would work only in a park with natural settings. He believes that Yellowstone has had an artificial(人为的) setting for a long time. The native people left. The wolves were taken away and other animals were removed. The areas of land were fenced off(隔开) and other animals added. He thinks the park rules that let herds grow too big and the fires are hurting the nature of the park.

    The park manager thinks the rules are good and that the park will be fine. Chase thinks the way the people run the park should be changed.

On our second day in China, we had already been asked to join the school for supper. Nervous and unsure of the food and table manners, we politely agreed. Coming to China, the thing I was most nervous about was the food, and now my first dining experience would be with the school staff. 

In Chinese culture the most important person sits facing the door. When plates of food started arriving, I wished I had practiced my chopstick skills before arriving in China. 

Chinese culture is all about being hospitable (好 客 的 ). This means ordering lots of food and encouraging you to keep eating. It also means drinking wine or tea. You'll never have an empty glass. 

It's polite to try everything, but if you know me, you would know l don't eat everything. Fresh fish? Sure, an entire fish on the plate staring at you while you pick at it. Not for me. Snails with their shell crushed and cooked into a meal?No thanks!The lung of a pig? I'll pass. It seems that the Chinese really eat everything!

The Chinese people are friendly. They want to learn about you and teach you about their culture. They like to ask questions, and it is polite to ask them many questions and keep the conversation going. 

Every day I'm pushed out of my comfort zone (舒 适 区 ). But for the most part, I discover something I really enjoy. The experience itself is quite amazing, I've learned a lot, yet there's still so much to learn. It surely is different from my culture and way of living, but being in their shoes and seeing life through their eyes has really helped me to understand. And I look forward to discovering more!

It's well-known that silk was discovered in China. It's wonderfully strong, light and soft. As one of the best materials for clothes, silk has a perfect look and feel that no other materials can match. 

There is a story about how silk was discovered. Lei Zu, the wife of Huang Di, was having tea under a mulberry tree when a silkworm cocoon(蚕茧)fell into her cup. As she tried to take the cocoon out, it started to unwind(展开)and the "line" seemed endless. She realized that the strong line could be used to make clothes. Then Lei Zu taught her people how to raise silkworms and how to get silk In this way, the silk industry was born. 

For hundreds of years after that, silk was only used by rich people. It was a symbol of identity and status(身份和地位). With the development of the silk industry, more silk was produced. It was no longer just for rich people. In the Han Dynasty, silk was transported as far away as Spain, Rome and many other counties. The trade road was famously known as the Silk Road, which connected China with the rest of the world

Today, silk can be used for many kinds of things, not just for clothes, bus also for paintings, writing brushes, kites and even fishing nets. Wherever silk goes around the world, it is always warmly received. 

 There is an old opera in Wenzhou. It is called Ou Opera or Wenzhou Opera. {#blank#}1{#/blank#}. It is more than 300 years old.

 Ou Opera has nice music. {#blank#}2{#/blank#} People usually use suona and erhu when they sing. Actors usually use Wenzhou dialect (方言) to tell stories. {#blank#}3{#/blank#} Sometimes, the stories are very funny.

{#blank#}4{#/blank#} More and more people from all over the world come to watch it. Ou Opera is a kind of traditional art in Wenzhou. As Wenzhou people, it's important to keep and share it.
