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 DVD’s success is just on 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, tile 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(基因组), 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 passage is based on the author’s ______.
选项 A、experience of the changes
B、admiration of the changes
C、hope for changes
D、analysis of the changes
答案B
解析 观点题，文章第一段以DVD为例，引出对a historic shift from analog to digital technologies的赞叹；第二段以photography为例，说明了数字产品的优势以及生活数字化的好处；第三段第一句话后半句虽然谈及负面影响，但作者主要强调digital revolution的优势。由此可见，作者在文章中主要表达了自己对数字技术变革的赞赏，因此选B。尽管文章结尾对the digital innovations寄予了很大期望，但这并不是作者在本文中想要表达的主要态度，因此可以排除干扰选项C。
