Last November, engineers in the healthcare division of GE unveiled something called the "Light- Speed VCT", a scanner that can create a startlingly good three-dimensional image of a beating heart. This spring Staples, an American office-supplies retailer, will stock its shelves with a gadget called a "wordlock", a padlock that uses words instead of numbers. The connection In each case, the firm’s customers have played a big part in designing the product.
How does innovation happen The familiar story involves scientist in academic institutes and R&D labs. But lately, corporate practice has begun to challenge this old-fashioned notion. Open-source software development is already well-known. Less so is the fact that Bell, an American bicycle-helmet maker, has collected hundreds of ideas for new products from its customers, and is putting several of them into production. Not only is the customer king: now he is market-research head, R&D chief
A. benefit from customer innovation.
B. challenge academic institutes and R&D labs.
C. are pioneers in adopting customer innovation.
D. are predominant in new products research.

[填空题]What categories are there based on digital division

[单项选择]Electrical engineers have repeatedly demonstrated that the best solid-state amplifiers are indistinguishable from the best vacuum-tube amplifiers with respect to the characteristics commonly measured in evaluating the quality of an amplifier’s musical reproduction. Therefore, those music lovers who insist that recorded music sounds better when played with the best vacuum-tube amplifier than when played with the best solid-state amplifier must be imagining the difference in quality that they claim to bear.
Which one of the following, if true, most seriously weakens the argument
A. Many people cannot tell from listening to it whether a recording is being played with a very good solid-state amplifier or a very good vacuum-tube amplifier.
B. The range of variation with respect to the quality of musical reproduction is greater for vacuum-tube amplifiers than for solid-state amplifiers.
C. Some of the characteristics that are important in determining how music sounds to a listener cannot be measured.
D. Solid-state amplifiers are more compact, use less power, and generate less heat than vacuum-tube amplifiers that produce a comparable volume of sound.
E. (E) Some vacuum-tube amplifiers are clearly superior to some solid-state amplifiers with respect to the characteristics commonly measured in the laboratory to evaluate the quality of an amplifier’s musical reproduction.
