       Imagine 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? Was he or she
angry, or did that person just forget to turn off the 'Caps Lock' on the computer? The fact is, this e-mail
'sounds' like the writer is shouting because using all capital letters in an 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 (规矩) often
called netiquette. Virginia Shea's book, Netiquette, lists a basic set of dos and don'ts for communicating
(交流) rightly with others online. 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 think about you by your words as well as your actions, so do try to write well.
Good writing skills, as well as correct grammar and spelling, do matter. Send polite, well-written e-mail
messages to others. If you're uncertain about how to spell a word or which phrase to use, look it up. There
are lots of helpful books and websites.
        It's okay to express your opinions online in forums like chat rooms or message boards, for example
"MSN" or "QQ", but don't start arguments with people. 'Flame wars' (网上论争) in online discussions can
be interesting to read, but are often unfair (不公平) to other members of the group. Express your ideas, but
remember that fighting (打架) on or offline is just not right. 
        When you're online, just as in 'real' life, try to respect other people's space, privacy, and feelings.
Remember, you're not the only one traveling on this highway!
