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 word "they" (Line 6, Para. 1) refers to______.
选项 A、the tiny silicon chips
B、the letters written on paper
C、the postmen, clerks and secretaries
D、the routine tasks performed by the postmen
答案C
解析 词义推断题。they所在的句子是第1段倒数第2句，本句中两个they的指代是一样的，因此，只要找到第一个they的指代就能找到答案了。根据本段倒数第3句中“Not only postmen but also clerks and secretarieswill vanish”及倒数第2句中的“All the routine tasks they perform…”可推断，they是指上一句中的postmen，clerks和secretaries。
