Encouraged by electronic mail39。s surprisingly high speed, convenience and economy, people who never before touched the stuff are regularly, skillfully, even cheerfully tapping out a great deal of correspondence.　　Electronic networks, woven into the fabric of scientific munication these days, are the route to colleagues in distant countries, shared data, bulletin boards and electronic journals. Anyone with a personal puter, a modem and the software to link puters over telephone lines can sign on. An estimated five million scientists have done so with more joining every day, most of them municating through a bundle of interconnected domestic and foreign routes known collectively as the Internet, or net.　　Email is starting to edge out the fax, the telephone, overnight mail, and of course, land mail. It shrinks time and distance between scientific collaborators, in part because it is conveniently asynchronous (writers can type while their colleagues across time zones sleep。 their message will be waiting). If it is not yet speeding discoveries, it is certainly accelerating munication.　　Jeremy Bernstei, the physicist and science writer, once called Email the physicist39。s umbilical cord. Lately other people, too, 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 cartoonan appreciative dog seated at a keyboard, saying happily, “On the Internet, nobody knows you39。re a dog.”　　41　The reasons given below about the popularity of Email can be found in the passage EXCEPT __________.　　A　direct and reliable　　B　timesaving in delivery　　C　moneysaving　　D　available at any time　　42　How is the Internet or net explained in the passage? __________　　A　Electronic routes used to read home and international journals.　　B　Electronic routes used to fax or correspond overnight.　　C　Electronic routes waiting for correspondence while one is sleeping.　　D　Electronic routes connected among millions of users, home and abroad.　　43　What does the sentence “If it is not yet speeding discoveries, it is certainly accelerating munication” most probably mean? __________　　A　The quick speed of correspondence may have illeffects on discoveries.　　B　Although it does not speed up correspondence, it helps make discoveries.　　C　It quickens mutual munication even if it does not accelerate discoveries.　　D　It shrinks time for munication and accelerates discoveries.　　44　What does the sentence “On the Internet, nobody knows you39。re a dog.”imply in the last paragraph? __________　　A　Even dogs are interested in the puter.　　B　Email has bee very popular.　　C　Dogs are liberated from their usual duties.　　D　Email deprives dogs of their owners39。 love.　　45　What will happen to fax, land mail, overnight mail, etc. according to the writer? __________　　A　Their functions cannot be replaced by Email.　　B　They will coexist with Email for a long time.　　C　Less and less people will use them.　　D　They will play a supplementary function to Email.　　31.
