Well, no gain without pain, they say. But what about pain without gain？ Everywhere you go in America, you hear tales of corporate revival. What is harder to establish is whether the productivity revolution that businessmen assume they are presiding over is for real.
The official statistics are mildly discouraging. They show that, if you lump manufacturing and services together, productivity has grown on average by 1.2% since 1987. That is somewhat faster than the average during the previous decade. And since 1991, productivity has increased by about 2% a year, which is more than twice the 1978-1987 average. The trouble is that part of the recent acceleration is due to the usual rebound that occurs at this point in a business cycle, and so is not conclusiv
e evidence of a revival in the underlying trend. There is, as Robert Rubin, the treasury secretary, says, a “disjunction” between the mass of business anecdote that points to a leap in productivity and the picture reflected by the statistics.
Some of this can be easily explained. New ways of organizing the workplace—all that re-engineering and downsizing—are only one contribution to the overall productivity of an economy, which is driven by many other factors such as joint investment in equipment and machinery, new technology, and investment in education and training. Moreover, most of the changes that companies make are intended to keep them profitable, and this need not always mean increasing productivity: switching to new markets or improving quality can matter just as much.
Two other explanations are more speculative. First, some of the business restructuring of recent years may have been ineptly done. Second, even if it was well done, it may have spread much less widely than people suppose.
Leonard Schlesinger, a Harvard academic and former chief executive of Au Bong Pain, a rapidly growing chain of bakery cafes, says that much “re-engineering” has been crude. In many cases, he believes, the loss of revenue has been greater than the reductions in cost. His colleague, Michael Beer, says that far too many companies have applied re-engineering in a mechanistic fashion, chopping out costs without giving sufficient thought to long term profitability. BBDO’s Al Rosenshine is blunter. He dismisses a lot of the work of re-engineering consultants as mere rubbish—“the worst sort of ambulance cashing.”

[A] not as good as it seems

SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：M. Annie, is family life in Britain very different from that in your country？
W. No, I don't think so. But I have noticed a few differences.
M. Oh, such as what？
W. Well, the family unit seems to be smaller here than in my country. For you, the family is simply Mum, Dad and the children.
M. You have a more extended family circle？
W. Yes. It's quite common in my country to have a grandmother and an unmarried aunt or uncle living in as part of the family. And we wouldn't dream of sending an elderly relative to an old persons' home.
M. You take care of elderly relatives yourselves, I gather.
W.. Yes. We haven't got all your welfare services and it's the family's duty to look after an elderly parent.
M. What about hospitality？ Do you think English families do a lot of entertaining？
W. Yes, but in a rather formal way. You don't like people to "drop in" without a previous invitation, do you？ In my country it's quite usual to drop in on friends and relatives.
M: Have you ever lived in with an English family？
W. Yes. I was an au pair girl for a year, helping with the housework. I learned a lot about English family life then. I'd never realized how fond the Englishman is of his home and family, his garden and his pets.
M. Did you enjoy living in with the family'？
W: Oh, yes. They were very kind. Everybody helped with the washing up, including the children, and we always found time to sip tea and watch television in the evenings !
What is an extended family according to the woman？
A．A family with father, mother and the children.
B．A family with a lot of friends dropping in.
C．A family with elderly and unmarried relatives.
D．A family with in-laws and married siblings.

C．encouraging
D．on the way to complete recovery
A.Ag(T+D)、Au(T+N1)和Au(T+N2)
B. Au(T+D)、Ag(T+N1)和Au(T+N2)
C. Au(T+D)、Au(T+N1)和Au(T+N2)
D. Au(T+D)、Au(T+N1)和Ag(T+N2)
(Au
|Au) = 1.68V(Au
|Au) = 1.50V，(Fe|Fe
) = 0.77V 则反应：2Fe+ Au= 2Fe+ Au的平衡常数
