Sending E-mails to Professors

One student skipped class and then sent the professor an e-mail {{U}}(51) {{/U}} for copies of her teaching notes.
Another {{U}}(52) {{/U}} that she was late for a Monday class because she was recovering from drinking too much at a wild weekend party.
At colleges and universities in the US, e-mail has made professors more approachable(平易近人 ). But many say it has made them too accessible, {{U}}(53) {{/U}} boundaries that traditionally kept students at a healthy distance.
These days, professors say, students seem to view them as available {{U}}(54) {{/U}} the clock, sending a steady stream of informal e-mails.
"The tone that they take in e-mails is pretty astounding(令人吃惊的)." said Michael Kessler, an assistant dean at Georgetown University. "They'll {{U}}(55) {{/U}} you to help: 'I need to know this. '"
"There's a fine {{U}}(56) {{/U}} between meeting their needs and at the same time maintaining a level of legitimacy (正统性) as an {{U}}(57) {{/U}} who is in charge. "
Christopher Dede, a professor at the Harvard Graduate School of Education, said {{U}}(58) {{/U}} show that students no longer defer to (听从) their professors, perhaps because they realize that professors' {{U}}(59) {{/U}} could rapidly become outdated.
"The deference was driven by the notion {{U}}(60) {{/U}} that professors were all-knowing sources of deep knowledge. " Dede said, and that notion has weakened {{U}}(61) {{/U}}.
For junior faculty members, e-mails bring new tension into their work, some say, as they struggle with how to {{U}}(62) {{/U}}. Their job prospects, they realize, may rest in part on student evaluations of their accessibility.
College students say e-mail makes {{U}}(63) {{/U}} easier to ask questions and helps them learn.
But they seem unaware that what they write in e-mails could have negative effects on {{U}}(64) {{/U}} them, said Alexandra Lahav, and associate professor of Law at the University of Connecticut.
She recalled an e-mail message from a student saying that he planned to miss class so he could play with his son. Professor Lahav did not respond.
"Such e-mails can have consequences. " she said. "Students don't understand that {{U}}(65) {{/U}} they say in e-mail can make them seem unprofessional, and could result in a bad recommendation. "
