Passage One

Questions 21 to 25 are based on the following passage.

①Many of today’s most trusted sales techniques were invented over a century ago by a young merchant named Eaton in Toronto.21 When he was young, Eaton worked briefly with his brothers in small-town stores. In 1869, he set up his own shop in downtown Toronto. He had many competitors, but he was also ambitious and had a plan for success. He offered a unique style. of trade, but as was expected, all the other shopkeepers laughed at him, believing he would eventually fail. However, Eaton was not a man to be easily defeated; he came up with（To bring forth or discover ） a brand new notion of business – “Goods satisfactory, or money refunded.(to give back)” He sold all his goods at fixed prices and only for cash.23

②With a sharp sense of what the public wanted, he went out of the way(To inconvenience oneself in doing something beyond what is required.不怕麻烦地：超出要求之外做某事而使自己麻烦) to meet their needs. His business grew rapidly. He set up new branches and started mail order service that allowed people to buy from a list of his goods.

③Eaton’s list—advertisements of his day—was the first of its kind. It was distributed and read all over the country. It was the only way to access good-quality goods at reasonable prices for people living far away from big cites.25 It became part of their life. They even called it The Wishing Book. The secret of the list’s success was that Eaton gained the respect of these customers22; they trusted him for good prices and quality goods. Probably because he remembered his miserable early days in Ireland, Eaton thought much of the welfare of his employees: better working conditions, shorter weekday（除了周日或者除了周六周日）hours than his competitors and Saturday afternoons off in the summer. In all this, he was a leader.
