Electronic MailDuring the past few years,scientists all over the world have suddenly found themselves pro-ductively engaged in task they once spent their lives avoiding—writing,any kind of writing,but particularly letter writing. Encouraged by electronic mail'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 communication these days,are the route to colleagues in distant countries,shared data,bulletin boards and electronic journals.Any-one with a personal computer,a modern and the software to link computers over telephone lines can sign on.An estimated five million scientists have done so with more joining every day,most of them communicating through a bundle of interconnected domestic and foreign routes known col-lectively as the Internet,or net.E-mail 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 conven-iently asynchronous（异步的）( Writer 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 communication.Jeremy Bernstein,the physicist and science writer,once called E-mail the physicist's umbili-cal cord（脐带）.Later other people,too,have been discovering its connective virtues. Physi-cists are using it;college students are using it;everybody is using it;and as a sign that it has come of age,the New Yorker has celebrated its liberating presence with a cartoon—an apprecia-tive dog seated at a keyboard,saying happily,“on the Internet,nobody knows you're a dog.” Why is a dog sitting before a computer keyboard in a cartoon published by New Yorkers?A: Even dogs are interested in the computer.B: E-mail has become very popular.C: Dogs are liberated from their usual duties.D: E-mai deprives dogs of their owners' love.

第一篇Electronic TeachingThe potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize" the school of tomorrow".Televised lessons will originate from a central building having perhaps four or five master studios.The lessons will be carried into classrooms all over a city,or even an entire country.After a televised lesson has been given,the classroom teacher will take over for the all important"follow-up"period.The students will ask any troublesome questions,and difficult points will be cleared up through discussion.The teacher in the classroom will have additional electronic tools.On the teacher's desk,the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape players.The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students' levels of ability.For instance,while the class as a whole studies history,each student will receive an individual history lesson,directed to his par-ticular level of ability.Should question arise,the students will be able to talk directly to the teacher on individual intercoms without disturbing the rest of the class.In this way,the teacher will be able to conduct as many as three classes at the same time.With the rapid development of computer science,students will be aided with specially prepared multi-media software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teachers' and get the score instantly.They will get certificates or diplomas if they pass all the required examinations.Experts believe that this type of education will be very popular in the years ahead.Computer teaching will help the study in the following ways except that_________.A:teachers can give and collect homework using electronic mail systemB:examinations can be conducted on computers better than on paperC:test scores can be obtained soon after the test is takenD:certificates or diplomas are required if the students want to pass the tests

问答题Practice 9 Electronic mail, or e-mail, is a method of transmitting message through a computer network. Business communication by e-mail is basically the same as writing on paper. Although e-mail tends to be a more immediate and personal form of communication, the formal style, tone and language of a business letter should still be employed. Try to avoid long and complicated words and sentences in your e-mail as to make the message easy to read. Keep paragraphs short and use line spaces between paragraphs.
