问题     Hardly a week goes by without some advance in technology that would have seemed incredible 50 years ago. And we can expect the rate of change to accelerate rather than slow down within our lifetime. The developments in technology are bound to have a dramatic effect on the future work. By 2020, new technology will have revolutionized communications. People will be transmitting more messages down telephone lines that previously have been sent by post. Not only postmen but also clerks and secretaries will vanish in a paper-free society. All the routine tasks they perform will be carried on a tiny silicon chip so that they will be as obsolete (已废弃的) as the horse and cart after the invention of the motor car. One change will make thousands, if not millions, redundant.
    Even people in traditional professions, where expert knowledge has been the key, are unlikely to escape the effects of new technology. Instead of going to a solicitor, you might go to a computer which is programmed with all the most up-to-date legal information. Doctors, too, will find that an electronic competitor will be able to carry out a much quicker and more accurate diagnosis and recommend more efficient courses of treatment. In education, teachers will be largely replaced by teaching machines far more knowledgeable than any human being. Most learning will take place in the home via video conferencing. Children will still go to school though, until another place is created where they can make friends and develop social skills.
The writer expects that by 2020 new technology will have revolutionized communications and______.
选项 A、people needn’t telephone each other
B、the present postal system will have disappeared
C、people will no longer send letters
D、the postmen will have been replaced by silicon chip
答案B
解析 事实细节题。本题考查对比处。作者在第1段第5句中通过previously将过去与现在作对比，指出现在传递消息的途径与过去不一样了，由此可判断B为正确选项。本题最具干扰性的是选项C，第1段倒数第3句提到以后邮递员将会消失，但这并不意味着人们不再写信和寄信，以后可能会有新的送信方式，因此选项C是不对的。
