Computer people talk a lot about the need for other people to become "computer literate", in other words, to learn to understand computers. Not all experts agree, however, that this is a good idea. One pioneer, in particular, who disagrees is David Tebbutt, the founder of computer-town UK. Although many people see this as a successful attempt to bring people closer to the computer, David does not see it that way. He says that Computer-town UK was formed just for the opposite reason, to bring computers to the people and make them "people-literate". David first got the idea when he visited one of America’’s best-known computer figures, Bob Albrecht. In a small university town in Northern California, Albrecht had started a project called Computer-town USA in the local library, and the local children used to call round every Wednesday to borrow some time on the computers there, instead of borrowing library books. Albrecht was always on hand to answer any questions and to help the children discover about computers in their own way. Over there, in Britain, Computer-towns have taken off in a big way, and there are now about 40 scattered over the country. David Tebbutt thinks they are most successful when tied to a computer club. He insists there is a vast and important difference between the two, although they complement each other. The clubs cater for the enthusiasts, with some computer knowledge already, who get together and eventually form an expert computer group. This frightens away non-experts, who are happier going to computer-towns where there are computers available for them to experiment on, with experts available to encourage them and answer any questions; they are not told what to do, they find out. David Tebbutt finds it interesting to see the two different approaches working side by side. The computer experts have to learn not to tell people about computers, but have to be able to explain the answers to the questions that people really want to know. In some Computer-towns there are question sessions, rather like radio phone-ins, where the experts listen to a lot of questions and they try to work out some structure to answer them. People are not having to learn computer jargons, but the experts are having to translate computer mysteries into easily understood terms; the computers are becoming "people-literate".When a computer-town is tied to a computer club, the experts play the role of the ________of the non-experts.

A.question raisers

B.authoritative teachers

C.encouraging instructors

D.partners to work on some programs

答案：C

解析：这是分析推理题。我们在第四、第五段都看到有关专家的作用的句子，例如：第四段中有“非专业人士则热衷于来到电脑城……旁边还有专家鼓励他们并回答各种问题。没人要求他们用电脑来完成什么，他们自己发掘计算机的用途”。第五段又提及：“电脑专家必须……能够解释人们确实想了解的问题……普通人无需学习电脑术语，而专家必须将神秘的计算机知识用人们耳熟能详的方式阐述”。这两段的内容都表明计算机专家在电脑城里的角色是鼓励他人使用电脑，并提供浅显易懂的解释。所以答案是C。
