问题     In 1997, devotees of home electronics eagerly awaited the DVD player, a new device that could play movies without videotape, and with greater clarity. It caught on even faster than CD music players and within four years, DVD movies surpassed VHS tapes in sales. The DVDs success is just one example of a historic shift from analog to digital technologies. They began with computing and are now spreading to industries from banking to publishing. Products and services are shedding the limits of their physical form to become encoded information that never degrades, can be reproduced perfectly and distributed around the world in minutes, or less.
    Another example is photography: by the end of this year, the number of images captured digitally each day is expected to surpass the number of images captured on film. With digital cameras and other devices linked to personal computers, we can collect vast amounts of data, which fortunately takes up little or no closet space. Today’s average personal computer has a hard drive that can store 300 times more information than a decade ago. Technologies, such as broadband e-commerce, are expected to be the primary means of delivering entertainment and media by the end of this decade. Even life itself is increasingly digitized. The human genome, the recipe for our genetic makeup, has been mapped and encoded and researchers are harnessing the power of computing to accelerate the development of new, lifesaving drugs.
    The implications of this broad, digital revolution are enormous, although they tend to be over-shadowed by the struggles of high-tech industries to recover from the go-go years of the 1990s. Those struggles are real, yet there are reasons for optimism about a return to robust economic growth and job creation in the next several years. The digital innovations(创新)of the past two decades continue to bear fruit, so stay tuned for good news--digitally, of course.
The author implies that excitement over the digital revolution may be hindered by _______.
选项 A、ignorance of the technology
B、robust economic growth
C、the economic realities of its practicality
D、economic problems of hi-tech companies
答案D
解析 推理判断题。题干中的hindered“阻碍”暗示了the digital revolution的背后除了excitement之外，还有不如意的地方。关键词digital revolution出现在第二段第一句，前半句总结上文，说明数字技术革命好的一面；后半句用although引导，则应该是不好的一面。over-shadowed与hindered意义相近，也就是说，the struggles of high-tech industries对数字技术革命造成了负面影响，而the struggles的目的是recover from the go- go years of the 1990s，也就是下句中的a return to robust economic growth，归根结底是这些高科技企业的经济问题。因此，选项D符合题意。
