问题     Video recorders and photocopiers(复印机), 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 YV, and after months of practice l 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 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 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 pubic trials would quickly reveal many design mistakes. In an ideal world, there would be some ways of controlling quality such ms 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.
One of the reasons why VCRs are so difficult to use is that ______.
选项 A、the desirers are often insensitive to the operational complexities of their machines
B、the range of features provided is unlimited
C、there is no ideal way of controlling quality
D、their designers often ignore the complaints of their uses
答案A
解析 细节题。本题问的是：VCR难以使用的一个原因是______。根据第2段第1句“First，the problems we notice are not obvious to technically minded designers with years of experience and trained to understand how appliances work”，可知我们注意到的问题对有着多年经验和受过电器工作原理培训的专业设计师来说并不是什么问题，设计师对机器操作的复杂性早已很熟练，因而他们对此并不敏感，故选A 。
