The Internet is becoming more and more important in our life. You can get a lot of information, make friends. share your ideas, send emails and chat at any time or anywhere. However, imagine you receive an email 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(大写) letters? Was he or she angry, or did that person just forget to turn off the ‘Cap lock’ on the computer? The fact is, using all capital letters in an email means that people shout online. Virginia Shea’ s book, Netiquette, lists some ways of communicating(交流) properly 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 write anything that you wouldn’t say to someone’s face. Also, remember that the receiver cannot hear your voice, or see the expression(表情)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 . Don’t use information that someone else has written, and say it’s yours. Don’t read other people’s email—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 do try to write well. Send polite, well-written email messages to others. If you’re not sure about how to spell a word or which phrase to use, look it up. There are lots of helpful books and websites.

◆It’s OK to share your ideas online like chat rooms or message boards, but don’t argue(争吵) with people . ‘Flame wars’ in online discussions can be interesting to read, but are often unfair(不公平) to other members of the group. Share your ideas, but remember that fighting on or offline is just not correct.

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