Questions 1~5 are based on the following passage: （10 分） How did a peddler of cheap shirts and fishing rods become the mightiest corporation in America? The short version of Wal -Mart’s rise to glory goes something like this：in 1979 it racked up billion dollars in sales；by 1993 it did that much business in a week ；by 2001 it could do it in a day . It’s a shocking tale — one that propelled Wal -Mart from rural Arkansas，where it was founded in 1962，to the top of the Fortune 500．Sam Walton ，Wal-Mart’s founder，pushed sales growth continuously while squeezing cost s with sophisticated information technology ．He exhorted employees to sell better with the “ten -foot rule” （greet customers if they are that close ）．He was ，in other words，an early evangelist for the first commandment of today’s economy ：service rules ．Wal-Mart ，in fact ，is the first service company to rise to the top of the Fortune 500．When Fortune first published its list of the largest companies in America in 1995，Wal-Mart didn’t even exist ．That year General Motors was America’s biggest company，and in every year that followed，either GM or another mighty industrial ，Exxon，was No．1. Wal-Mart’s achievement caps a bigger economic shift — from producing goods to providing services．Manufacturing’s share of U．S．employment peaked in 1953，at 35% ．It has been declining steadily since ．In the decade that will end in 2010，the Bureau of Labor Statistics figures that goods-producing industries will create 1.3 million new jobs，compared to 20 million for service industries ．To look at it another way，today there are about four times a s many people working in service jobs as in other kinds of jobs ．And even within manufacturing，services are an increasingly large share of operations . As America got richer，consumption got more complicated ．With more income to throw around ，people started spending more on services — movies and travel，mortgages to buy houses ，insurance to protect those houses ，the occasional weekend s at a luxury hotel ．Fortune calls this a shift in the demand pattern ．Over the next few years，only three of the ten fastest-growing oc cupations （software engineers ，nurses ，and computer support ）pay middle-class salaries．The rest could be called Wal-Mart kinds of jobs — cashiers，retail assistants，food service ，and so on ．In short ，the service economy is delivering more good jobs than ever before.In 1993, W al-Mart could have a sales volume of two billion dollars in ______.
