It shrinks time and distance between scientific collaborators，in part because it is conveniently asynchronous(异步的)(Writers can type while their colleagues acmss time zones sleep;their message will be waiting.).If it is not yet speeding discoveries，it is certainly accelerating munication.        Jeremy Bernstein，the physicist and science writer，once called E-mail the Dhysicist，s umbilical cord(脐带).Later other people，t00，have been discovering its connective virtues.Physicists are using it;college students are using it;everybody is using it;and as a sign that it has e of age，the New Yorker has celebrated its liberating presence with a cartoon—an appreciative dog seated at a keyboard，saying happily，“on the Internet，nobody knows you’re a dog.”1.[不定向选择题]What does the sentence“If it is not yet speeding discoveries.it is certainly accelerating conmunication”most probably mean?A.The quick speed of correspondence may have ill effects on discoveries.

D.It shrinks time for munication and accelerates discoveries. 2.[不定向选择题]Why is a dog sitting before a puter keyboard in a cartoon published by the New Yorkers?A.Even dogs are interested in the puter.
