resulting spread of bad English does more harm than good.Email is a form of communication that is changing, for the worse, the way we write and use language, say some communication researchers.It is also changing the way we interact(交流) and build relationship.These are a few of the recently recognized features of email, say experts, which should cause individuals and organizations to rethink the way they use email.“Email has increased the spread of careless writing habits， ”says Naomi Baron, a professor of linguistics (语言学) at an American university.She says the poor spelling, grammar, punctuation and sentence structure of emails reflect(反映) a growing unconcern about the way we write.Baron argues that we shouldnt forgive and forget the poor writing often shown in email.“The more we use email and its tasteless writing, the more it becomes the normal way of writing， ” the professor says.Others say that despite its poor writing, email has finished what several generations of English teachers couldnt：it has made writing fashionable again.“Email is a critical new communication technology.” says Ian Lancashire, a professor of English at Toronto University.“It fills the gap between spoken language and the formal methods of writing that existed before email.It is the purest form of written speech.”Lancashire says email has the mysterious ability to get people who are usually scared by writing to get their thoughts flowing easily onto a blank screen.He says this is because of emails close similarity to speech.“Its like a circle of four or five people around a campfire， ” he says.Still, he accepts that this newfound freedom to express themselves often gets people into trouble.Emails sent in a day almost exceed (超过) the number of letters mailed in a year.But more people are recognizing the content of a typical email message is not often exact.【语篇解读】本文是说明文。文章介绍了电子邮件使写信这种古老而传统的沟通方式又恢复了生机，但用电子邮件写信也带来了一些新的问题，专家们对此也有不同的看法。1.From what Baron says in the third
