It's the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell phones. They want to log on to their micro blogs to check the interesting things that have happened in the last hour.
　　Since last year, the trend of micro blogging has swept the country. Recent surveys shows that most students in middle schools have a micro blog and some even update their blogs over five times per day.
　　"We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Andy Liang, 14. "If you do not know about them, you are out of the loop."
　　It is also a great place for students to let out stress. "My parents always ask me to study all the time, and encourage me before exams, but it really adds pressure," said Simon Zhang, 15. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."
　　But parents are worried that micro blogging could be a waste of time. Some misleading messages may even cause danger to kids, they said.
　　Mr. Shen, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about micro blogging. Maybe it can become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, thus leading to better communication and solutions to problems," he said. He also gives some tips for kids.
　　—Don't micro blog for more than one hour a day.
　　—Never micro blog in class.
　　—Try to talk face to face with people from time to time.
　　—Be critical. Don't trust all the messages on a micro blog.

    We spoke to three students from around the world about different national holidays．There are different customs (习俗) for each festival．

    “It'll be Chinese New Year soon．Before it we'll clean the house and decorate(装饰) it for good luck．Every shop is going to close for a few days and we'll go out a lot to celebrate in the streets．We might go and see the lion and dragon dances in the city center．I love this festival．”

    Wendy, 16, Sydney, Australia

    “Australia Day is on 26th January and it's an important holiday here．We always have a Monday off, so we celebrate for three days．My parents and I go to the countryside for a picnic and friends always come over．Many people go to beach parties or street parties and there's lots of music and dancing．What fun!”

    Amy, 14, New York, the USA

    “The first Thanksgiving Day was hundreds years ago when Europeans who came to America thanked God for his help．It's still a very important day for families to be together．This year we're going to visit my parents and we'll eat a delicious meal of turkey．Thanksgiving Day is on the fourth Thursday in November every year．”

When I was about 12 years old,I had an enemy(敌人), a girl who liked to tell me about my weak points. Week by week, her list of the weak points became 1 - I was very short, and I wasn't a good student! I talked too much, and so on. I tried to stand all of these as long as I could. Finally, I became very 2 . I ran to my father with tears in my eyes.

 He listened to me 3 , and then asked, "Are the things that she said true or not? Jane, have you ever thought about what you' re really like? Now you have that girl's 4 . Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things that she said. "

I did as he told me. To my great 5 , I found that half of the things were true but the others I couldn't agree with. Some of them I couldn't 6 , like being very short, but many of them I could. I wanted to change the bad things. And for the first time I knew something about myself in a very clear way.

I brought the list back to my father. He didn't 7 it." That's just for you, "he said, "You know the 8 about yourself better than everybody else, but sometimes others' words are also important, so you have to learn how to 9 and not just close your cars in anger and feel hurt. When something that is said about you is true, you' ll find that it will be helpful to you. "I have remembered my father's 10 at many important moments. Now I don't think that girl is my enemy any longer, because she made me to be a better one.
