Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the rivers, or on the grassland, you should know that your sport of choice might have great influence on the environment.
② Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all kinds of harmful things and a lot of energy are used to keep its courses(球场)，This leads to serious environmental problems. For example, in Portugal and Spain, golf is considered to be the most important reason for water shortage(短缺）io some areas.
③ There are many environment-friendly sports. Power walking is one of them that you could do today. You don't need anything special but a good pair of shoes; and you don't have to worry about nature and your money. Simple and free, power walking -can also keep you fit. If you often walk, it will be good for your heart and bones.
④Nowadays more and more people choose to play "green sports". They play sports outdoors, in the countryside or other open spaces. There is no special things needed. And best of all, it's free.

    I love to write! Ever since I was a five-year-old girl, I wrote stories in my notebooks and on small pieces of paper. I told stories to my friends. As a grown-up, I have written over 100 books! That's a lot! As a teacher, it's my goal to encourage all of my students to love to write.

    Writing is easy if you're careful enough, I told them. Everyone I meet is a possible character.

    Everything I see or do is a possible scene in a book. Start looking around you. You'll be amazed at what you discover.

    Anyone can be a writer. You just put your pencil on your paper and write what you like to read, step by step:

    ● Create great characters. If you know your characters well, they'll write the story for you.

    ● Interest the reader right at the beginning. You can start your stories with dialogue or action. If you can make the reader ask questions, then he has to keep reading to find out the answers.

    ● Follow the steps. The steps for every story are almost the same: Introduce the characters and the conflict(争端);things get worse; all seems lost; the hero saves the day!

    ● Balance is the key.

    Remember, when writing, it doesn't hurt to add some humor(幽默).

    My name is Jerry Zhang, and I am a father of two young daughters -- one is about four years old and the other is only about one.我来自中国，现在住在美国。

    One day, my older daughter, Madison, told me she didn't want to be Chinese. Those days she was quite interested in the book characters (角色) Madeline and Eloise. She asked me all the time why she was Chinese and they weren't, and how she could have yellow or red hair like them.

    This made me look for books with Asian (亚洲的) characters for Madison to read. However, I only found a few, and they were heavily cultural (文化的) and Madison didn't connect herself with any of the characters in them. And she wash' t interested in them at all Then she told me again that she didn't want to be Chinese, and it made me sad.

    In most of the books for children in the US, the characters look like Americans. There are over 17 million Asians and Asians and Americans in this count, but few of them have Asian faces. I think it's important for Asian children to see themselves in books as interesting and clever kids.

    So I created (创作) a book for Madison. Pepper Zhang in the book is an Asian girl. Her imagination (想象) takes her on a trip to creativity and art I want my children to know that being Chinese or being Asian is a great thing too.

    On her way home from school the other day, Yang Xi found people looking at her with strange expressions.The 15-year-old Shandong girl felt embarrassed, but she knew they were looking at her school uniform.

    There were some pictures and words on the back, such as“Dear Yang Xi, I will miss you after graduation.”Her friends did it in class.And Yang wrote something on her friends' uniforms too after class.

    Like Yang, many students now use the school uniform as if it were a piece of white paper and draw on it.They draw pictures of their favorite singers,athletes and cartoon characters and so on.“I think  (1)   (wear) a school uniform with graffiti is a kind of campus fashion,”said Yang.

    ①As a matter of fact, most schools have strict rules that require students not to draw on uniforms. Otherwise, they will be punished (惩罚).They may be told to clean their uniform or more seriously, to buy a new one.

    ②However,it seems that some students are not afraid of the rules and punishment.“I think there are at least 100 students with  (2)   (paint) uniforms in my school.They walk around the campus ‘proudly'.I wonder if they care whether they will be punished at all,”said Li Fei,13 of Fujian.

    Li Yong,14 of Heilongjiang, had his own view.“I have seen cartoon figures such as Naruto(火影忍者) and Doraemon(哆啦 A梦) that students draw on their uniforms.They are really beautiful and creative.I think graffiti can make students become creative,”said Li.“But it's better not to draw on uniforms.”

    Although he doesn't think his school uniform looks good, Li would never draw on it.It's a strict school rule there, after all.I have to follow the rules.”
