Yahoo, MSN and AOL offer software that allows users to have real-time conversations in text windows online. Instant messages are typed so fast that users dont slow down to change into capital letters, add punctuation, or write complete words. As a result, new word abbreviations and IM slang are being made up faster than a high-speed modem.,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-3,Keyboard Nation3 A typical instant-messaging conversation lasts morethan a half hour, includes three or more friends and often includes friends from different places. More than one inthree IM users say they use it every day. Nearly half of online teenagers believe that the Internet has improved their friendships. Its a quick, easy way to keep in touch.4 Twelve-year-old Gabbi Lewin said that shes on instant messenger almost every day. She says that without it, “there would be no way to communicate. Our parents are on the phone all the time.”,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-4,5 Thirteen-year-old Steven Mintz likes messaging betterthan the phone “because I can talk to more people at once.” Chatting online is also a good way to keep up with friends who live far away. Children dont have to worry about the phone bill. Wrong Message?6 Instant messaging does not always help develop afriendship. Sometimes, children use it to show angry feelings. Such children arent really trying to be mean. Often its just easier to say something online than in person. Eleven year-old Oliver Davies says, “I can express my feelings more easily with IM, without the guilty feeling of saying it face-to face.”,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-5,7 Many parents and teachers think childrens instantmessaging habits are taking their attention away from more important things. Julia Long says that when her son, Taylor, 13, “is waiting for a beep, its hard (for him) to stay focused on homework or any kind of family activity.”8 Teachers get upset when Internet slang and emoticons (faces made with punctuation marks) appear in childrens writing. Words that have troubled young writers, including “its” and “its,” now have been joined by “u, ” “r” and “wuz.”,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-6,9 Childrens safety may also be a problem. Staying connected is fine, but an online friendship with a stranger is not. Many parents monitor instant messaging, either by limiting time online or by keeping the computer in a common area. IM Not So Bad 10 Researchers who study children and the Internet say instant messaging isnt getting in the way of real life. They note that new technology often produces old fears.” Its similar to what was said in the 1980s about video games and in the 1960s about television. There was this worry that children would do nothing else.”,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-7,11 Even parents and teachers who dont like IM have to admit that at least children are writing. And their typing skills are improving. Is it at the expense of proper English? “Not so long as they learn the difference between formal and conversational English,” says Naomi Baron, a professor of linguistics.,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A-8,12 “Language has always changed, and it always will,” says Baron. “It must change as the things we do and the things we meet change.” Thats good news!,Text A,Comprehension,Words and Expressions,Vocabulary Building,Text Study,Text A- Comprehension1,A.
