| Imagine you receive an e-mail that looks something like this: ARE YOU GOING TO CLASS TODAY? How does 1 this message make you feel? 2 did the sender use all capital letters? Was he or she angry, or did that person just 3 to turn off the "Caps Lock (大写的)" on the computer? This e-mail "sounds" like the 4 is shouting because using all capital letters in an e-mail is usually the way that people shout 5 . Knowing when and where not to use capital letters is just one 6 of online manners. Don't do anything on line that you wouldn't do in 7 life. Don't use information that 8 else has written, and 9 it's yours. Do share your knowledge of the 10 with others. | ||||
