　　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 the Internet or cellphones. To newcomers, it can look like a completely foreign language.

　　School teachers 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 Nurnberg, 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 Milroy says, for centuries, it is believed without exception that young people are harming the language. And 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 tell their pupils that text messaging is for fun, but that learning to write proper English is a must for their future."
