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 on their machines to record a program: they don’t use it because they’ve found it far too hard to operate.
    So why do manufacturer 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 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 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 per cent of the features correctly 90 per cent of the time.
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 细节题。本题考查对第一段的理解，要求找出作者难以操作VCR的原因。作者一开始就指出"Video recorders…often seem unnecessarily difficult to use"，消费者发现有些功能"…far too hard to operate"，作者在第二段的开头提出了问题"So why do manufacturer keep on designing and producing VCRs that are awkward to use if the problems are so obvious?"，因此"VCR操作起来远比技术人员预期的要困难"是正确答案。"他忽视了使用定时器的重要性"与"他没有经过培训就使用VCR"与文意明显不符。作者在第二段确实提到"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"，但在第三段又说。Why can’t you have features that are easy use?"，可见作者不反对多功能，而是强调使用方便，所以"VCR有太多不必要的功能"不是作者的原意。
