Video recorders and photocopiers, even ticket machines on the railways, ofte

问题     Video recorders and photocopiers, even ticket machines on the railways, often seem unnecessarily difficult to use. Last December I bought myself a video cassette recorder (VCR) described as "simple to use". In the first three weeks I failed repeatedly to program the machine to record from the TV, and after months of practice I still made mistakes. I am not alone. According to a survey last year by Ferguson, the British manufacturer, more than one in four VCR owners never use the timer (定时器) on their machines to record a programme: they don’t use it because they’ve found it far too hard to operate.
    So why do manufacturers keep on designing and producing VCRS that are awkward to use if the problems are so obvious? First, the problems we notice are not obvious to technically minded (有技术思想的) designers with years of experience and trained to understand how appliances work. Secondly, designers tend to add one or two features at a time to each model, whereas you or I face all a machine’s features at once. Thirdly, although finding problems in a finished product is easy, it is too late by then to do anything about the design. Finally, if manufacturers can get away with selling products that are difficult to use, it is not worth the effort of any one of them to make improvements.
    Some manufacturers say they concentrate on providing a wide range of features rather than on making the machines easy to use. But that gives rise to the question, "Why can’t you have features that are easy to use?" The answer is you can.
    Good design practice is a mixture of specific procedures and general principles. For a start, designers should build an original model of the machine and try it out on typical members of the public—not on colleagues in the development laboratory. Simple public trials would quickly reveal many design mistakes. In an ideal world, there would be some ways of controlling quality such as that the VCR must be redesigned repeatedly until, say, 90 percent of users can work 90 percent of the features correctly 90 percent of the time. [br] The author had trouble operating his VCR because______.
选项 A、he had neglected the importance of using the timer
B、the machine had far more technical features than necessary
C、he had set about using it without proper training
D、its operation was far more difficult than the designer intended it to be
答案 D
解析 本题问作者在操作他的卡式录放机时有困难的原因是什么。此题是道具体细节问题。利用查阅式阅读法，我们可以在文章第一段中找到相关信息。作者在文章开头以其亲身经历抱怨卡式录放机难于操作。作者说他买的卡式录放机用着不顺手，这并不稀奇，连厂家调查也表明四分之一以上的人从不使用某些功能，因为太难操作了。因此，本题的正确答案应是D“卡式录放机操作起来远比设计人员预期的要难”。
