年12月大学英语四级考试真题答案 篇2
among the more colorful characters of leadville’s golden age were h.a.w.tabor and his second wife, elizabeth mccourt, better known as “baby doe”. their history is fast becoming one of the legends of the old west. horace austin warner tabor was a school teacher in vermont. with his first wife and two children he left vermont by covered wagon in to homestead in kansas. perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in colorado mines. at any rate, a few years later he moved west to the small colorado mining camp known as california gulch, which he later renamed leadville when he became its leading citizen. “great deposits of lead are sure to be found here.” he said.
as it turned out, it was silver, not lead, that was to make leadville’s fortune and wealth. tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco.『it was his custom to “grubstake” prospective miners, in other words, to supply them with food and supplies, or“grub”, while they looked for ore, in return for which he would get a share in the mine if one was discovered.』①he did this for a number of years, but no one that he aided ever found anything of value.
finally one day in the year , so the story goes, two miners came in and asked for “grub”. tabor had decided to quit supplying it because he had lost too much money that way. these were persistent, however, and tabor was too busy to argue with the “oh help yourself. one more time won’t make any difference,” he said and went on selling shoes and hats to other customers. the two miners took $17 worth of supplies, in return for which they gave tabor a one-third interest in their findings. they picked a barren place on the mountain side and began to dig. after nine days they struck a rich vein of silver. tabor bought the shares of the other two men, and so the mine belonged to him alone. this mine, known as the “pittsburgh mine,” made 1 for tabor in return for his $17 investment.
later tabor bought the matchless mine on another barren hillside just outside the town for $ . this turned out to be even more fabulous than the pittsburgh, yielding $35 worth of silver per day at one time. leadville grew. tabor became its first mayor, and later became lieutenant governor of the state.
