well-roasted coffee bean.But the Starbucks Coffee Co.leader was undoubtedly the first to turn thatdream into a billion dollar retail business.Schultz's adventure started in 1981 when he traveled from New York to Seattle to check out apopular coffee bean store called "Starbucks".It had been buying many of the Hammarplast Swedishdrip coffeemakers(滴滤式煮咖啡壶)he was selling.There was that great smell,sure,but what caused him to fall in love with the business was thecare the Starbucks owners put into choosing and roasting the beans.He was also impressed with theowners'devotion to educating the public about the wonders of the coffee.It took Schultz a year to convince the Starbucks owners to hire him.When they finally madehim director of marketing and operations in 1982,he had another idea.This one occurred in Italy,when Schultz noticed the coffee bars that existed on almost every block.He learned that they notonly served excellent espressos(蒸馏咖啡)，they also served as meeting places or public squares,and there were 200,000 of them in the country.But when he came back to Seattle,the Starbucks owners resisted Schultz's plans to serve coffeein the stores,saying the restaurant business was competitive,and it was costly to hire waiters.Afterall,economic benefits were their primary motivator.Frustrated,Schultz quit and started his owncoffee-bar business in 1985,named"II Giornale".It was successful,and two years later,the originalStarbucks management sold its Starbucks retail unit to Schultz for $3.8 million.As the company began to expand rapidly in the 1990s,Schultz always said that the main goalwas "to serve a great cup of coffee".Asked about the secret of his success,Schultz told us theprinciples:"Don't be threatened by people smarter than you.Compromise anything but your corevalues.”24.What caused Schultz to join the Starbucks?A.The pleasant smell of its coffee bean.B His strong desire to improve himself.C.The owners'impressive work attitude.D.His eagerness to sell more coffeemakers.25.Which of the following can best describe Schultz's personality?A.Committed and generous.B.Sociable and helpful.C.Motivated and considerate.D.Determined and creative.26.Why did the Starbucks owners refuse to serve coffee in the stores?A.Many coffee bars had existed in SeattleB.People preferred tasting coffee at home.C.Workforce was insufficient in the market.D.They tried to avoid high cost of labor force.27.What does Schultz think contributes to his success?A.Learning from smarter people.B.Sticking to his own core values.C.Keeping his business a secret.D.Remembering a set of principles.《新高考学科基地秘卷》命题高三英语·共10页，第4页
