I can tap my smartphone and a cab will arrive almost immediately. Another tap will tell me the latest news, value my share portfolio or give me route directions to my next meeting. As a result, I do not need to stand on a street corner vainly trying to hail a taxi to the theatre, lose myself in London streets. The changes that have occurred in the past decade have, from an economic perspective, increased at virtually no cost the efficiency of household production.
The data framework within which economic analysis is conducted is largely the product of the second world war. In the 1930s American economist Simon Kuznets began to elaborate a system of national accounts. That work was given impetus when the war led governments to take control of important sectors of economic activity. It was soon realized that this required far better data than had previously existed, which in turn raised the challenge of how best to structure such information.
Household production—women’ s work as homemakers—did not have much of a look-in; that was not the front line against fascism. The joke about the man who reduced national income by marrying his housekeeper, so that a market transaction became part of household production, was once a mandatory part of every introductory course on national income accounting but has
succumbed to
political correctness.
Technological advance has always enhanced household as well as business efficiency. Our domestic productivity has benefited from washing machines, vacuum cleaners and central heating, and before that from electric light and automobiles. But at least these things were partially accounted for: from an economic perspective a car is a faster and cheaper horse. Statisticians in principle incorporated these improvements in the efficiency of consumer goods into their measurement of productivity, though in practice they did not try very hard.
But the technological advances of the past decade seem to have increased the efficiency of households, rather than the efficiency of businesses, to an unusual extent. An ereader in the pocket replaces a roomful of books, and all the world’ s music is streamed to my computer. We look at aggregate statistics and worry about the slowdown in growth and productivity. But the evidence of our eyes seems to tell a different story.
It can be implied from the first paragraph that______.
选项
A、a new smartphone is created
B、the new smartphone has changed people’ s life
C、there are many changes in the past decade
D、economically speaking, the changes have improved the efficiency of household production
答案
D
解析
推断题。根据题干关键词the first paragraph定位至第一段。根据第一段的最后一 句The changes that have occurred in the past decade have,from an economic perspective, increased at virtually no cost the efficiency of household production。此句意为“从经济学视 角看,这些发生在过去十年的变化,几乎在没有任何成本的情况下提高了家庭生产的效 率。”可知D项“从经济角度来说,这些变化提高了家庭生产率”,符合题意,为正确答案。 A项“一种新型的智能手机被创造”,B项“新型智能手机改变了人们的生活”和C项“在 过去的十年产生了许多变化”都是对第一段表面文字的描述。而首段之所以描述智能手 机对人们生活产生的影响均是为了说明最后一句:这些变化对家庭生产率的影响。故前 三项均不正确。
