[单项选择]In the early days of the inbox, it afforded the naive human organism a certain pleasure to receive an e-mail. So a note or two of greetings whistled through the lonely day. Thanks to e-mail, the eloquence of a moribund letter-writing culture received a rejuvenating jolt of immediacy. As late as the late 1990s and early 2000s, during the last days of dial-up, it still felt nice to send and receive the occasional squib, to play a game of catch with some friends. Sometimes you would even forward a joke, a practice that nowadays seems a crime.

It’s the old story: the new efficient technology ends up costing far more time than it ever saves, because it breeds new expectations of what a person can possibly do. So commuters in their fast cars spend hours each day in slow traffic, and then at the office they read and send e-mail.
Correct e-mailing practice does not exist. The true mood of the form is s
A. briskness.
B. accuracy.
C. willingness.
D. preoccupation.
