     My summer hols wr CWOT. B4, we used 2 go 2 NY 2C my bro, his CF & thr 3:-@ kids FTF ILNY,

its gr8.   

     Can you understand this sentence? If you can't, don't feel too bad: neither could the middle school teacher

in England who received this as homework. This is Netspeak: the language of computerized communication

found on Internet or cellphones. To newcomers, it can look like a completely foreign language.So, what is

the "translation" of the sentence above? My summer holidays were a complete waste of time. Before, we

used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face. I love

New York; it's great.   

     Schoolteachers and parents say this new form of writing is harming (破坏)the English language.

Increasing spelling and grammatical mistakes can be seen in students' writing. They fear the language could

become corrupted (面目全非的).   

     Everyone should just relax, say linguists (语言学家). They believe Netspeak is in fact more of a good

thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language

use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford

University, agrees."People get better at writing by writing," he says, "Kids who are now doing text messaging,

e-mail, and instant messages will write at least as well as, and possibly better than, their parents."   

     Linguist James Millroy says, for centuries, it is believed without exception that young people are harming

the language. And you can bet your bottom dollar that when today's teenagers become tomorrow's parents,

they too will think this way. Milroy argues that languages do not and cannot become"corrupted"; they simply

change to meet the new needs.   

     However, Netspeakers do agree that it is important to teach young people how to speak and write Standard

English. Cynthia McVey says, "I can understand Netspeak worries teachers and it's important that they get

across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their

future."   

     Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn't use text

language in my homework. Texting is just for fun"
