roponents of IT arguedQ22 to Q25:
Most pre-1990 literature on busi-
nesses’ use of information technology
(IT)—defined as any form of computer-
Line based information system—focused on
(5) spectacular IT successes and reflected
a general optimism concerning IT’s poten-
tial as a resource for creating competitive
advantage. But toward the end of the
1980’s, some economists spoke of a
(10) “productivity paradox”: despite huge IT
investments, most notably in the service
sectors, productivity stagnated. In the
retail industry, for example, in which IT
had been widely adopted during the
(15) 1980’s, productivity (average output per
hour) rose at an average annual rate of
1.1 percent between 1973 and 1989, com-
pared with 2.4 percent in the preceding
25-year period. roponents of IT argued
(20) that it takes both time and a critical mass
of investment for IT to yield benefits, and
some suggested that growth figures for
the 1990’s proved these benefits were
finally being realized. They also argued
(25) that measures of productivity ignore what
would have happened without investments
in IT—productivity gains might have been
even lower. There were even claims that
IT had improved the performance of the
(30) service sector significantly, although mac-
roeconomic measures of productivity did
not reflect the improvement.
But some observers questioned why,
if IT had conferred economic value, it did
(35) not produce direct competitive advantages
for individual firms. Resource-based
theory offers an answer, asserting that,
in general, firms gain competitive advan-
tages by accumulating resources that are
(40) economically valuable, relatively scarce,
and not easily replicated. According to
a recent study of retail firms, which con-
firmed that IT has become pervasive
and relatively easy to acquire, IT by
(45) itself appeared to have conferred little
advantage. In fact, though little evidence
of any direct effect was found, the fre-
quent negative correlations between IT
and performance suggested that IT had
(50) probably weakened some firms’ compet-
itive positions. However, firms’ human
resources, in and of themselves, did
explain improved performance, and
some firms gained IT-related advan-
(55) tages by merging IT with complementary
resources, particularly human resources.
The findings support the notion, founded
in resource-based theory, that competi-
tive advantages do not arise from easily
(60) replicated resources, no matter how
impressive or economically valuable
they may be, but from complex, intan-
gible resources.
Q25:
According to the passage, most pre-1990 literature on businesses’ use of IT included which of the following?
答案是； E，但是文中第一段第一句话就说：
Most pre-1990 literature on busi-nesses’ use of information technology (IT)—defined as any form of computer- based information system—focused on spectacular IT successes and reflected a general optimism concerning IT’s potential as a resource for creating competitive advantage.
可见E不对阿。请教！
IT’s potential as a resource for creating competitive advantage.
可见E很对阿。请教！
According to the passage, most pre-1990 literature on businesses’ use of IT included which of the following?
推荐方式方法没有提到。
肯定没有两方面都说，否则就不会吃惊的发现“productivity paradox”
人力资源哪个是第2段内容，是后来的研究，不是1990年前的研究成果排除。
没有警告，否则也不会有“productivity paradox”。警告都是后来发现问题才可能警告的。
