[单项选择]Email has brought the art of letter writing back to life, but some experts think the 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 dramatically changing the way we interact and build relationships. These are a few of the recently recognized features of email, say experts, that 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 at American University. She says the poor spelling, grammar, punctuation and sentence structure of emails reflect a growing unconcern to the way we write.
Baron argues that we should not forgive and forget the poor writing often shown in emails. "The more we use email and its tasteless writing, the more it becomes the normal way of writing," the professor says.
A. will reinforce our critical awareness.
B. will lead to failed relationship
C. will affect your intelligence and capabilities.
D. will not replace formal writing.
