    My name is George．I'm from England．Now I'm studying in Germany．I get to school at 7：30 every morning．I find many of my schoolmates come to school by bike．  ①   

    This is an interesting thing for me．In England people usually drive，take a bus or walk somewhere，for example，to school．In Germany, I often see people，even people over eighty years old going somewhere by bike．It makes me think：  ②   

My father gives the answer．We are living in Northern Germany．It is very flat(平坦的).So it is easy for people here to go somewhere quickly by bike .And it's cheaper than(比…….便宜)going by car or by bus．Also,it's good for the environment(环境)．

    I like riding bikes now．   ③    When I go back to England，I will ride more and ask my friends to ride with me．I think they will like tiding bikes，too．

    Earth Hour started at 7:30 p.m. on March 31,2007 in Sydney, Australia. More than 2.2 million homes and businesses turned off their lights for an hour.

    A year later, March 29,Earth Hour 2008 became a global(全球的)activity.50 million people in 35 countries took part in it.

    On March 28, 2009, more than2100 cities in 88 countries joined in it. And the idea “Earth hour” came to China. What were people doing during the Earth Hour? Here are some people's answers:

    Ann: I'm a university student. I invited some of my friends to go out. During the Earth Hour, we were having a candle light concert on the playground. We also talked about the happy times we spent in the university.

    Julie: I turned off the lights in my house and went for a walk during the Earth Hour. It was a little strange to walk in the dark. But I think it is exciting and meaningful.

If you receive an e-mail that looks something like this:

    ARE YOU GOING TO CLASS TODAY? How does reading this message make you feel? Why did the sender use all capital letters(大写字母)? Was he or she angry, or did that person just forget to turn off the 'Cap Lock' on the computer? The fact is, this e-mail is usually the way that people shout online. Knowing when and when not to use capital letters is just one example of online etiquette(礼仪) —often called 'netiquette'. Virginia Shea's book, Netiquette, lists a basic set of dos and don'ts for communicating suitably with others on the Internet. Following are some of her suggestions.

    First, always remember that you are sending messages to a real person, not just to a computer. Don't type anything that you wouldn't say to someone's face. Also, remember that the person who receives your message cannot hear the tone of your voice, or see the expression on your face, so make sure your meaning is clear.

    Don't do anything online that you wouldn't do in real life. Don't take anything without paying for it, unless it's free. Don't use information that someone else has written, and say it's yours. Don't read other people's e-mail—you wouldn't open your next-door neighbor's mailbox and open their mail, right? Do share your knowledge of the Internet with others. It's a big place with lots of information, and there are many new things to discover.

    Remember that people judge(判断) you by your words as well as your actions, so try to write well. Good writing skills, as well as correct grammar and spelling, matter(有关系). Send polite, well-written e-mail messages to others. If you're uncertain about how to spell a word or which phrases to use, look it up. There are lots of helpful books and websites.

    It's okay to show your ideas online in forums(论坛) like chat room or message boards, but don't start arguments with people. 'Flame wars' in online discussions can be interesting to read, but are often unfair to other members of the group. Express your opinions, but remember that fighting online or offline is just not suitable.

    When you're online, just as in 'real' life, try to respect(尊重) other people's space, privacy and feelings. Remember, you are not the only one travelling on this highway!

    Zhang Zhouchen, a sixth grader, has published two novels in English.“Most people often read to learn English, but my secret is to write ”he said. "Reading is a way of taking in. But only when you use it for writing can you master it completely. “

    Zhang began writing his first novel at the end of 2014. He didn't mean to publish it at first. But a special experience made him change his mind the next year. He was chosen by his school to be a volunteer for a Hope Primary School. Every volunteer was asked to bring a gift for children and Zhang brought a football. "But I was surprised to find that there was no football field at this school, "he said. “So I had a wish to help them build a football field.

    How to achieve that? The novel came into Zhang's mind suddenly. By organizing the book sale, he got 100,000 yuan. He then spent it building a football field. Then he got about 130, 000 yuan by selling his second novel. He used the money to build a football field in another school.

    “I can never forget the smiles on the faces of the children who were having fun playing football, said Zhang. "It encourages me to help more poor children enjoy the joy of football.
